Abstract. This The integrated power system(IPS) to be used in future ships will be a big leap in the building of ship power platforms, representing the prospective direction of in the development of ship power systems. A centralized control console with PLC(Programmable Logic Control) and touch screen has been designed for the propulsion subsystem of the vessel integrated power system. The centralized control console is mainly used to monitor the operations of the propulsion motor and propulsion inverter and to make remote control communications with the propulsion display and control console of energy management. This paper has made a detailed description of its hardware, software and communication, and given full account of the PLC program as well as the process of the start-up, speed regulation and shutdown performed by the propulsion subsystem under local or remote control. The site tests prove that the designed centralized control console can effectively monitor the running conditions of the propulsion subsystem and improve the digitalization, intelligent capability, stability and reliability of the vessel integrated power system, which will be of reference value to the research on ship automatic management and long-distance monitoring. Introduction The vessel integrated power system(VIPS) is an integral system which will generates electricity and supplies it to daily service loads, propulsion system and shipboard devices. Thus, it is possible to make a unified and centralized control of power generation, power distribution, power consumption, electric propulsion, and other electrical devices. The news type system is regarded as a major breakthrough in the development of ship power platform, making the tread towards the state-of-the-art ship power system. It has also drawn wide attention of the world's navies consensus[1-2]. Because of its high efficiency, good reliability, high automation and low-cost maintenance, the electric propulsion system as one of the ship’s power systems is becoming a main contemporary large surface ships. Now, the system of this kind have been used in the ships newly built by developed countries. Furthermore, the ship electric propulsion subsystem is a key module of the VIPS because it can converter the DC energy form the rectified generator into the variable frequency AC power needed to drive the induction motor and then change it into the mechanical energy required for driving the propeller through the induction propulsion motors . With a growing improvement in the electrification and automation of ships, the centralized monitoring and management systems which can meet all the parameter indexes are becoming more and more important in the ship’s entire system. A good monitoring system can greatly reduce labor intensity, increase working efficiency, improve the stability, security and reliability of the ship in operation, and enhance its combat effectiveness [3-4]. The PLC (programmable logic control) and the touch screen are much better than the computer control system in stability and anti-interference under harsh marine conditions. As the touch screen has such advantages as easy operation, robustness, fast response and less space, it has been widely used in the field of industrial control. Moreover, the use of it has led to the settlement of many problems the computer cannot solve. Its software is characterized by powerful function, short development cycle, simple operation, easy maintenance. With a combination of display, operation and debugging and data storage, it is obviously superior to other display devices [5-7]. All rights reserved.

(ID: 130.203.136.75, Pennsylvania State University, University Park, USA-17/05/16,03:29:30) 348 Advances in Mechatronics, Automation and Applied Information Technologies In view of the electric propulsion subsystem, this paper has designed a propulsion subsystem control console based on ABB's AC500-series PLC and Kinco Automation company’s MT5720-series touch screen. The control console is mainly used for the local monitoring of the operating state of the propulsion motors and propulsion drivers and the communication with the energy management propulsion display and control units (remote control) of the IPS. Based on Modbus TCP / IP protocol, the control console incorporates the propulsion motor, PLC, two touch screens and the programming debugging interface into a network via Ethernet, with the special features of fast remote-access speed, strong real-time performance, high system security and low cost. And it is very easy to debug at an initial stage. The PLC and the main controller of propulsion driver adopt a flexible ASCII free communication protocol which can imitate any known messages and communicate with the energy management display and control units using Modbus RTU protocol, which is almost a serial communication preferential protocol. Modbus RTU protocol is simple, its hardware is cheap, and it’s strong in compatibility, so that it is easy to develop and implement. Hardware design of propulsion subsystem control console The propulsion subsystem control console include the host computer with touch screens and the lower computer with PLC. Because the propulsion subsystem needs to monitor and control many parameters, it is difficult to display all the key information on a single page. If the status monitoring and control is conducted on one touch screen, there is need for switching many over, which will affect the real-time and accurate monitoring and control. For this reason, the host computer is fitted with two touch screens—one mainly responsible for monitoring and recording the operating state of the propulsion subsystem and the other for controlling the subsystem. The propulsion subsystem control console is shown in the figure below.

Propulsion subsystem control console is mainly composed of Emerson UPS power supply, two 15-inch Kinco touch screens MT5720T-DP, ABB's PLC modules including the CPU module PM592-ETH and CPU motherboard TB541-ETH, digital input/output modules DC532 and DC522, analog input/output modules AX522, serial communication expansion module CM574-RS, Ethernet communication extension module CM577-ETH, Ethernet hub, some relays, buttons and lights. Connections between external devices and the control console. The connections between the promote subsystem control console and the external devices are shown in Figure 2, in which a solid line represents the direction of energy flow. The connections between the control console and the external devices are described as following: ① Between the control console and the multi-pole rectifier generator there is an optical fiber communication line, which is used for the generator’s emergency drop-out when the propulsion subsystem breaks down; ② The connections between the control console and the medium voltage switchboard mainly involve the main switch controlled by switching-in and switching-off signals and the corresponding state feedback hard line, whose signal aims at ensuring that the main switch can trip off at the fastest speed when the propulsion subsystem fails; ③ The control console and the propulsion driver are mainly connected by an optical fiber communication line and a discharge-control-signal hard line; ④ The connection between the control console and the propulsion motor mainly depends on an Ethernet communication line; ⑤ The Figure 1.

Software design for propulsion subsystem control console Software functional design for control console. The monitoring software of the control console is centered on the control and real-time monitoring of the device parameters of the propulsion subsystem, with the characteristics of perfect function, simple operation and good visibility. The specific functions are described as follow. 1) Monitoring the operations of the propulsion motor and the inverter and making communications with the propulsion display and control units. 2) Fault detection, alarm and treatment. 3) The display, storage and printing of failure information. 4) Control function of propulsion subsystem. 5) Safety function. Control console software program design. Control console software consists of PLC control software and touch screen HMI software. PLC program perform the functions of external communication, data processing, logical judgment, control and storage. The touch-screen program gets direct access via Ethernet and modifies PLC variables to meet the needs for displaying, controlling and storing the information of the propulsion subsystem. PLC program design of control console. The programming software Control Builder Plus of ABB Company is selected for the PLC of the control console of propulsion subsystem. PLC program is based on the most popular programming system CoDeSys, using ST programming language. ST language is compiled in a free plain text mode, without any fixed format restrictions. Like C language, it is a highly-automated programming language. PLC program is mainly composed of the logical interlock parameter limitation subroutine, propulsion motor communication subroutine, propulsion inverter normal data transceiving subroutine, propulsion inverter fault data transceiving subroutine and propulsion inverter failure emergency stop subroutine. The top four procedures work in parallel in a fixed cycle mode. The running cycle is 10 ms. But the failure emergency-stop subroutine adopts a free-cycle operating pattern, in which the main switch can trip off at the fastest speed in case of failure or emergency. The program flow is shown in Figure 3. program start program start inverter in“local”mode system initial finish yes motor data instruction logical interlock request send subroutine parameter limitation motor feedback data subroutine receive subroutine program end propulsion motor data HMI display subroutine motor data upload to energy management subroutine beginning, end and length of messages meet demand yes inverter receive data save subroutine inverter fault data request propulsion inverter instruction send subroutine failure emergency inverter fault data stop receive subroutine subroutine beginning, end and length of fault data meet demand yes inverter Data HMI display subroutine control console/security cabinet Inverter Receive “main switching on”feedback ineffective signal yes Inverter can charge needs “charge”and“confirmation”signal program end Inverter without “comprehensive fault”、no discharge and emergency button release inverter fault data save subroutine yes motor control instruction send subroutine program end yes propulsion inverter data receive subroutine inverter data upload to energy inverter fault data HMI management subroutine display subroutine local local/remote local instruction receive subroutine remote remote instruction receive subroutine propulsion inverter instruction send subroutine propulsion inverter instruction save subroutine program end program end receive main switch “switching on admissIon” effective signal yes Inverter send“main switching on”signal to medium voltage switchboard（2s pwm） yes inverter Receive“main switching on” Feedback signal yes with“confirmation”signal inverter“charge”signal can automaticall cancell Inverter give out “start-up”signal in local Inverter give out target speed in local Target speed in the range of -nmax~-nmin or nmin~nmax yes Inverter give out “confirmation”signal Motor rotating according target speed target speed=0 and actual speed less than +/-k rpm no yes Inverter automaticall stop Inverter give“main switching off”signal（2s pwm） Inverter receive “main switching on”Feedback Ineffective signal yes Inverter can discharge， need“discharge”and “confirmation”signal Discharge finish， cancell“discharge”signal， needs“confirmation”signal program end Figure 3. PLC flow chart of propulsion Figure 4. PLC local control process subsystem PLC local control program. The local control of the propulsion system refers to start-up, speed adjustment and stop. The control process is shown in Figure4. 350 Advances in Mechatronics, Automation and Applied Information Technologies Start-up: ① The control console is in the local operation mode. When the main switch is turned off, the inverter can be charged. ② After that, the main switch can be turned on and will disconnect the charging switch. ③ Given an effective target speed and a start-up signal, the inverter will start and the propulsion motor will run at the target speeds. Speed adjustment: The adjustment of speed aims at allowing the propulsion motor to run at the new target speed. Stop: ① With the given target speed as 0, the propulsion inverter will automatically stop after the actual speed of the motor is less than + /-k. ② The main switch will trip off after the shutdown of the inverter. At this time the inverter can discharge. ③ After the discharge is ended, the discharge instructions can be cancelled, with the stopped time over. PLC remote control procedures. The remote control of propulsion subsystem also can involves start-up, speed adjustment and stop. Its corresponding flow chart is shown in Figures 5~7. Start-up: ① The control console is in the remote control operating mode. After the remote control system give a signal requested for start-up, the propulsion inverter will start to be charged. ② After the charging is over, the control console will give a signal that the inverter is ready. When the remote system has received the signal, the main switch will automatically be on. ③ The charging switch will automatically be off after the control console receives the switching-in feedback of the main switch. ④ When the remote control system sets a given effective target speed and gives a start-up signal, the propulsion inverter will start and the propulsion motor will run at the target speed. Speed adjustment: The purpose of speed adjustment is to make the propulsion motor operate according to the new target speed. Stop: ① With the given target speed of the remote control system as 0, the inverter will automatically shut down after the actual motor speed of the motor is less than + /-k. ② The main switch will automatically be off after the remote control system receives the ineffective start-up signal. ③ The inverter will automatically discharge after the control console receives the effective switching-off feedback signal. ④ When the inverter finishes discharging, the discharge instructions will be cancelled automatically, with the stopped time over. program start remote system receive“remote feedback” signal yes inverter don`t have “comprehensive fault”and motor don`t have temperature high fault and emergency button release yes inverter receive remote system“start-up request”and “confirmation”signal yes inverter“charge” signal effective program start inverter feedback “inverter get ready”signal program start remote system receive “inverter get ready” signal in 180s no no yes remote system send “main switching on”signal to medium voltage switchboard（2s pwm） remote system “standby”button signal effective yes remote give target speed “fine speed up or down ” signal change target speed inverter receive no “main switching on feedback” signal yes inverter“charge” signal cancell start fail target speed in the range of -nmax~nmin or nmin~nmax yes inverter DC bus voltage greater than ux yes remote system give target speed=0, and“confirmation”signal start success inverter received “start”and“confirmation” signal yes motor rotating according target speed remote system adjust speed over yes program end remote system send “main switching off”signal to medium voltage switchboard motor speed reduce inverter receive “main switching off feedback” signal target speed=0 and actual speed less than +/-k rpm yes inverter“charge” signal effective yes inverter“start-up” signal ineffective inverter “start-up feedback”signal ineffective yes inverter DC bus voltage greater than uy yes inverter “discharge” signal cancell program end program end Figure 6. The inverter Figure 7. The inverter speed-regulation process under stopping process under remote remote control control Design of touch screen monitor interface. The host computer of the control console uses Kinco HMIware programming software developed by Shanghai Kinco Automation Co Ltd. The software, which is a special HMI programming software developed for the MT4000/5000 series, has a powerful integrative development capability. It can be used to create the operator panels and configure operating parameters for HMI. It can also provide various necessary means ranging, from data acquisition to the creation and display of pictures for the design of HMI projects. According to the specific functions of monitoring software, the design of software includes the following monitoring interfaces. ①Main monitoring interface. The Main monitoring interface can intuitively display the working state of the entire propulsion subsystem, including the input voltage and output current in each channel of the inverter, the switching status and the rotating speed of the propulsion motor. ②Monitoring interface of propulsion inverter. This monitoring interface displays all the states of the propulsion inverter so that an operator will be able to have a complete grasp of the running state of the inverter. ③Monitoring interface of propulsion motor. This monitoring interface displays all the Figure 5. The inverter start-up process under remote control Advanced Materials Research Vols. 846-847 351 states of the propulsion motor so that an operator can know the running state of the motor thoroughly. ④ Failure recording interface. This interface can automatically keep the past fault information of the system on file for failure analysing, displaying the type of failures and the date and time when faults occured and ended. ⑤ Data trend chart. The formation of the data trend chart depends on a fixed-time display of continuously varying data, including the given rotational speed and actual speed of the propulsion motor, and the output excitation current and torque current of the propulsion inverter. ⑥ Operation log. The recording of all the information of the propulsion subsystem must be done by a local or remote-control operator so as be convenient for inquiry and check.⑦ System setting. The system setting means setting the system parameters, such as language, time and local IP. ⑧ Remote access interface. The touch screen has remote access capabilities. As soon as a user inputs IP on it, he will get access to the monitoring interface via a PC. ⑨ Log-in interface. For the control of the touch screen, a log-in password is set to prevent irrelevant personnel from wrong operation. Communication design of propulsion subsystem control console The PLC of the propulsion subsystem is responsible for communication with two Kinco touch screens, the main controller of propulsion inverter, the propulsion motor and the propulsion display and control units of energy management while the PLC of control console make communication with the external, as shown in Figure 8. external debugging port multi-pole rectifier generator Generator’s emergency drop-out signal Ethernet Energy management propulsion display and control units of IPS propulsion inverter control or feedback signal inverter discharge signal Serial RS485，Modbus RTU communication Ethernet HUB High speed fiber ring main controller of propulsion inverter Modbus TCP/IP communication Modbus TCP/IP communication Serial RS232，ASCII free communication Modbus TCP/IP communication HMI1 （control） Serial port serial RS485，Modbus RTU communication (standby） Serial Ethernet port Extended HMI0 （display） Serial port Serial port Ethernet AX522 port port CM574 CM577 analog -ETH input/ -RS Ethernet port output port port RS485 RS232 CPU PM592-ETH DC532 Ethernet port ABB-PLC Ethernet port Modbus TCP/IP communication DC522 digital digital input/ input/ output output serial RS485，Modbus RTU communication (standby） main switching control and state feedback signal medium voltage switchboard control console of propulsion subsystem Modbus TCP/IP communication propulsion motor Figure 8. Diagram of PLC in communication with external devices In Figure 8 , the thick solid line stands for the signal hard line, thin solid lines for the Ethernet communication lines, the dotted lines for optical fiber communication lines, and dashed lines for serial communication lines. The figure shows that PLC is connected with the two touch screens, the propulsion motor and the external debugging port by the Ethernet hub and communicates with the propulsion inverter and the propulsion display and control units respectively via serial ports RS232 and RS485. Besides, there is a standby serial port RS485 for the communication between PLC and touch screens. Communication between touch screens and PLC. Communications between PLC and two touch screens depends on industrial Ethernet based on Modbus TCP/IP mode, which is characterized by the openness of protocol, good compatibility with different devices remote access, distant diagnosis, high network speed, strong real-time performance, high system security and low cost. Compared with the serial RS485, Modbus TCP/IP allows many addresses to be used and makes the transmission rate reach the level of GB/s by use of the multi-master architecture. Although only restricted by the physical capability of the network, The number of slave stations of Modbus TCP network is usually 1024. As Kinco touch screen can not support the Ethernet communication protocol of ABB’s PLC temporarily, the general-purpose module Modbus TCP Slave is chosen and applied to PLC in the configuration of touch screens. Two touch screens HMI0 and HMI1 and PLC are connected together via the Ethernet Hub. HMI0 is used for displaying the operating states of the propulsion inverter and motor while HMI1 is used for the correlative control of the propulsion inverter and motor, the setting of parameters and the remote 352 Advances in Mechatronics, Automation and Applied Information Technologies control of energy management propulsion display and control units. Multiple master-slave modes are not allowed to be used generally in communication. Therefore, both touch screens can not serve as masters at the same time. Here, HMI0 is used a master and PLC0 as a slave. The self-defined protocol of Kinco Company is adopted for the communication between HMI0 and HMI1. The specific setting of communication refers to TABLE 1. It is worthy of note to set IP of the two touch screens and PLC in the same network segment. In order to improve the reliability of the control console, its PLC and two touch screens need a standby serial RS485, with master-slave communication schemes based on Modbus RTU protocol. TABLE I. THE SETTING COMMUNICATION BETWEEN TWO TOUCH SCREENS AND PLC Device name HMI0 HMI0 HMI1 PLC0 IP addresses 192.168.0.252 192.168.0.252 192.168.0.253 192.168.0.110 Port No. 502 2008 2008 502 Communication protocol Modbus TCP Kinco Kinco Modbus TCP Slave mode Master slave Communication between the control console PLC and the propulsion motor. The PLC and the security cabinet of propulsion motor use Ethernet based on Modbus TCP/IP protocol for master-slave communication, with the control console as a master and the security cabinet of the propulsion motor as a slave. The main purpose is to display the temperature, flow, pressure and power of the propulsion motor and conduct an on-and-off control of the solenoid valves. Since the Ethernet port owned by PLC has been used for the communication of two touch screens of the host computer, PLC functions as a slave. However, according to the Ethernet communication requirements, PLC should serve as a master for its communication with the security cabinet of the propulsion motor. Therefore, the Ethernet communication extension module CM577-ETH is used to extend the Ethernet communication port of PLC. The module has two Ethernet ports, either of which can be applied to communication with security cabinet based on Modbus TCP/IP. Thus, PLC acts as a master. For the convenience of debugging, the other Ethernet communication port of the module is connected to the Ethernet hub to make easy for a PC to have access to the security cabinet through Ethernet. Communication between the control console PLC and the propulsion inverter. The PLC and the main controller of the propulsion inverter use RS232 serial port for communication according to ASCII free protocol. The main purpose is to monitor and control each switching devices of the inverter and the system’s operation, faults, input voltage and output current and to implement a speed setting and display, on-and-off control, charge-and-discharge control as well as a set-up of the related control parameters. The advantages of ASCII free communication protocol including the capability of defining its own data format, great flexibility, strong customization and the ability to imitate any communication protocol with a message known. Its disadvantages refer to lower data transmission and poorer universality. As these is a lack of cyclic redundance check, the communication between the PLC and the main controller of the propulsion inverter by use of ASCII free communication protocol, the addition of messages at the beginning and the end of communication and the check of the length of messages can improve the reliability and correctness in the communication between the PLC and the main controller of propulsion inverter. Communications between the control console PLC and the energy management display and control units. The PLC and the energy management display and control units use RS485 serial port for master-slave communication according to Modbus RTU protocol. Considering the distance is relatively long, the fiber-optic mode is used instead of the serial mode in communication, with the control console as a slave station and the energy management display and control units as a master station. In order to realize the functions of displaying the operations of the propulsion inverter and motor, adjusting the speed of the inverter and starting or stopping it, Modbus RTU protocol adopts a question-and-answer way in communication, with the advantages of simple mode, cheap hardware, strong universality, convenience, and easy development and implementation. The 16-bit CRC check can guarantee the correctness of communication. Now, Modbus RTU has almost become the most Advanced Materials Research Vols. 846-847 353 preferable serial communication protocol for the domestic PLC. It is more efficient than Modbus ASCII in communication at the same rate of baud. Communications between the control console PLC and other devices. As for the PLC program or items on the touch screen, the online debugging, uploading and downloading can be down through the Ethernet. The network is so practical as to make it convenient for an individual to have a quick access to the PLC and the touch screen. For example, it will take about 10 minutes to download the information on the touch screen via a serial port but less than half a minute to do so through Ethernet. The way of downloading the PLC information is similar, too. The data saved by PLC can also be acquired with remote access method through the Ethernet based FTP mode. More important control commands are directly connected with the PLC digital input/output module through the hardware. Moreover, there are hard lines which connect the control console, energy management propulsion display and control units, medium voltage distribution boards, rectifier generators and inverter cabinets respectively. Test results The application of the developed propulsion subsystem control console to controlling the propulsion motor and propulsion inverter has verified that the design of the control console is correct and feasible. The coaxial connection of the propulsion motor with hydraulic dynamometer, which is used to simulate the propeller load (with a linear relationship with the cubic of the speed), has resulted in the formation of a cubic relationship between the output shaft power of the propulsion motor and its rotating speed. Figures 9 show the sectional drawings of what are being displayed on the touch screens of the propulsion subsystem control console at the time of testing the propulsion motor together with the hydraulic dynamometer. nmax Motor full load， Speed nmax nmin -nmin -nmax (a) control interface (b) the given and measurement speed Corresponding Speed nmin Corresponding Speed -nmin Motor full load， Speed -nmax (c) exciting and torque currents Figure 9. The display of control interface of propulsion subsystem control console The control interface of the propulsion subsystem control console are mainly used to set the rotating speed, speed-up rate, speed-down rate, rotor resistance and flux parameters of the propulsion motor and to display the exciting current of the propulsion inverter. The prime mover of IPS is the gas turbine. It needs loading linearly while the load of the hydraulic dynamometer and the rotating speed of the propulsion motor form a cubic linear relationship. For linear loading, the rotating speed of the propulsion motor that is set by the propulsion inverter needs to form a subtriplicated relation with time. As shown in Figure 9(b), when the propulsion motor runs at -nmax ~ + nmax rpm, its actually-measured coincides well with the given speed. The control strategy of the propulsion inverter is the magnetic field vector orientation. In the forward-and-backward running test of the propulsion motor, the output field current id1 of the inverter remains stable; and it torque current iq1 will linearly increase with the rotating speed -nmax~-nmin and nmin~nmax cubic of the propulsion motor (Cubic speed refers to Figure 9(c)). When the speed of propulsion motor is in the range of -nmin~nmin, the load of the hydraulic dynamometer is small, iq1≈0 (iq1≈10000, corresponding to the full load of the propulsion system).

Summary Based on the PLC and touch screens, the propulsion subsystem control console has been designed in this paper, using the communication protocols based on Modbus TCP /IP, Modbus RTU and ASCII. The control console incorporates the propulsion motor, PLC, two touch screens and the programming debugging interface into a network by use of Ethernet. The network makes it convenient to do initial debugging. Through the field tests the vessel integrated power system, the design for the control console is proved to be correct and practicable. And the design methods and ideas of the propulsion subsystem control console can provide a reference for the automation and intelligence of future ships.
