Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to an integrated platform door controller simulation system and method. Background Technology

[0002] With the continuous upgrading of urban rail signaling systems, the various interfaces between urban rail signaling systems and integrated platform door controllers have placed higher demands on timeliness and maintainability while ensuring system safety and reliability.

[0003] Currently, various simulation software programs targeting different interfaces operate independently, with varying operation methods and interface designs. However, during testing, it is necessary to simultaneously analyze the output data of all software programs to verify the accuracy of the tests. This results in lengthy and complex operation steps, negatively impacting testing efficiency. Furthermore, the lack of a dedicated testing platform with multiple hardware interfaces prevents centralized and unified hardware interface integration testing. Simulation software programs targeting different interfaces typically employ independent data configuration modes, failing to effectively reuse configuration files with common attributes, thus increasing the workload of data configuration and test verification. When adding external interface simulations, the inability to quickly expand based on the existing simulation system necessitates the development of independent interface simulation modules, leading to a continuous increase in the number of simulation software programs and further complicating testing and usage. The test control unit operates independently from each simulation software program, making it difficult to efficiently coordinate the entire testing process and quickly and accurately verify the correctness of test results.

[0004] To conduct complete, accurate, and efficient functional testing of an integrated platform door controller based on a 2x2 safety platform that achieves a safety integrity level of SIL4, it is necessary to design and develop simulation software architecture. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0040] The following is combined with Figures 1-9 The present invention describes an integrated platform door controller simulation system.

[0041] Please refer to Figure 1 , Figure 1 This is a boundary diagram of the integrated platform door controller simulation system provided in this embodiment of the invention. Figure 1 As shown, the system includes: an operation control display terminal 1, a general-purpose hardware interface platform 2, and at least two Ethernet switches ( Figure 1 (Not shown in the image).

[0042] The operation control display terminal 1 is equipped with multiple simulation modules, which are used to simulate the logical functions of the corresponding core equipment in the urban rail signaling system.

[0043] Optionally, the multiple simulation modules include at least two of the following: a simulated Door Control Unit (DCU) module, a simulated Power System module, a simulated Integrated Backup Panel (IBP) module, a simulated Platform Screen Doors Local Control Panel (PSL) module, a simulated Gap Detection module, a simulated Vehicle On-Board Controller (VOBC) module, a simulated Computer Interlocking (CI) module, a simulated Integrated Supervisory Control System (ISCS) module, and a simulated Input / Output (IO) Relay module.

[0044] The general-purpose hardware interface platform 2 is equipped with multiple hardware interfaces, enabling centralized and unified hardware interface integration testing. Optionally, the multiple hardware interfaces include at least two of the following: a Controller Area Network (CAN) bus interface, a serial port, and an I / O hardwired interface. The general-purpose hardware interface platform 2 also has an Ethernet interface for Ethernet communication connection with the operation control display terminal 1.

[0045] At least two Ethernet switches are used to establish redundant multi-network connections between the operation control display terminal 1 and the general-purpose hardware interface platform 2, and to connect the integrated platform door controller 3 and the integrated platform door controller monitoring unit 4 to the operation control display terminal 1 for communication. The general-purpose hardware interface platform 2 is used to communicate with the integrated platform door controller 3 and the integrated platform door controller monitoring unit 4 through corresponding hardware interfaces.

[0046] Optionally, the operation control display terminal 1 and the general hardware interface platform 2 are connected via two Ethernet switches for dual-network redundancy. When communication data packets are too long, the application autonomously performs network data packet splitting and reassembly. This embodiment is not limited to this; four Ethernet switches can also be used for four-network redundancy.

[0047] The operation control display terminal 1 is used to provide an operation control display interface for the simulation test process (e.g., real-time modification of the status of associated equipment, drive-and-collection linkage control of equipment status, sending and pausing communication data, and fault injection control, real-time display of internal equipment status, real-time display of the status of external interface channels and main / standby status, real-time display of the status of the entire station area, etc., with the equipment being the smallest control unit within the software). Based on the read common basic configuration data and the configuration data of each simulation module, the basic functions of each simulation module are initialized, and the communication process between each simulation module and the integrated platform door controller 3 and the integrated platform door controller monitoring unit 4 is simulated and tested.

[0048] The following section provides a detailed explanation of the workflow and communication protocols of the operation control display terminal and the general hardware interface platform, as well as the communication methods of each simulation module.

[0049] In one embodiment, such as Figure 2 As shown, the workflow of the operation control display terminal may include steps 201-206.

[0050] Step 201: Initialize the internal state of each simulation module and redirect the internal state of each simulation module to the safe side.

[0051] Step 202: Read the common basic configuration data and the configuration data of each simulation module, and initialize the basic functions of each simulation module.

[0052] Specifically, first, common basic configuration data is read. Next, after reading the common basic configuration data, the configuration data of each simulation module is traversed. Then, based on the common basic configuration data and the configuration data of each simulation module, the basic functions of each simulation module are initialized. Since the common basic configuration data with shared attributes is reused when initializing the basic functions of each simulation module, the workload of data configuration and testing verification can be reduced.

[0053] Step 203: Start the threads of each simulation module.

[0054] Step 204: Utilize the threads of each simulation module to poll and receive various non-Ethernet interface data forwarded by the general hardware interface platform, as well as Ethernet interface data sent by the integrated platform door controller and the integrated platform door controller monitoring unit, and distribute them to each simulation module for logical processing.

[0055] Specifically, the threads of each simulation module periodically poll to receive non-Ethernet interface data (i.e., various types of non-Ethernet interface data forwarded by the general hardware interface platform) and external Ethernet data (i.e., Ethernet interface data sent by the integrated platform door controller and the integrated platform door controller monitoring unit), and distribute them to each simulation module for logical processing.

[0056] Step 205: After the logic processing is completed, send the corresponding non-Ethernet interface data to the general hardware interface platform, and send the corresponding Ethernet interface data to the integrated platform door controller or the integrated platform door controller monitoring unit.

[0057] Specifically, after the logic processing is completed, the corresponding non-Ethernet interface data (e.g., periodic and non-periodic representation data and operation control data information) is immediately sent to the general hardware interface platform, and the corresponding Ethernet interface data (e.g., protocol data information) is sent to the integrated platform door controller or the integrated platform door controller monitoring unit.

[0058] Step 206: Refresh the station layout graphics and update the operation control display interface in real time.

[0059] In one embodiment, the general-purpose hardware interface platform further includes multiple hardware interface modules, such as... Figure 3 As shown, the workflow of the general hardware interface platform may include steps 301-305.

[0060] Step 301: Initialize the internal state of each hardware interface module and redirect the internal state of each hardware interface module to the security side.

[0061] Specifically, the hardware interface module is a functional module within a general-purpose hardware interface platform responsible for processing the corresponding hardware interface data, such as an RS485 interface module or a CAN bus interface module.

[0062] Step 302: Initialize each hardware interface and start the threads of each hardware interface module.

[0063] Specifically, each hardware interface is opened and enabled, and the threads of each hardware interface module are started, such as RS485 thread, CAN thread, etc.

[0064] Step 303: Receive non-Ethernet data from each simulation module sent by the operation control display terminal, and distribute it to the threads of each hardware interface module for logical processing.

[0065] For example, simulated DCU status data is distributed to the CAN thread, and simulated power system status data is distributed to the RS485 thread.

[0066] It should be noted that the simulated IO relay drive data is directly driven externally through the IO interface.

[0067] Step 304: Receive non-Ethernet data sent by the integrated platform door controller or the integrated platform door controller monitoring unit, and forward it to the operation control display terminal.

[0068] Step 305: After the logic processing is completed, send the corresponding non-Ethernet data to the integrated platform door controller or the integrated platform door controller monitoring unit.

[0069] The communication protocol between the operation control display terminal and the general hardware interface platform is shown in Table 1.

[0070] Table 1

[0071] The key internal states of the platform include primary / backup status, operating status of each hardware interface channel, and interrupt information.

[0072] The communication methods of each simulation module are shown in Table 2.

[0073] Table 2

[0074] The following is combined with Figure 4 The communication connections and communication processes of each simulation module are explained in detail.

[0075] In one embodiment, such as Figure 4 and Figure 5As shown, the simulated DCU module communicates with the general-purpose hardware interface platform through two Ethernet switches, and with the integrated platform screen door controller through a CAN bus interface and an IO hardwired interface. The uplink DCU information corresponding to N platform screen doors is represented as uplink DCU-1, uplink DCU-2, ..., uplink DCU-N, and the downlink DCU information corresponding to N platform screen doors is represented as downlink DCU-1, downlink DCU-2, ..., downlink DCU-N.

[0076] The general-purpose hardware interface platform is specifically used for: The integrated platform gate controller receives the first uplink DCU information and the first downlink DCU information corresponding to each platform gate periodically transmitted through two CAN bus physical channels using the CAN2.0B protocol, and forwards them to the simulated DCU module through the Ethernet dual-network channel; the first uplink DCU information includes the status query frame and parameter setting frame of the platform gate in the up direction, and the first downlink DCU information includes the status query frame and parameter setting frame of the platform gate in the down direction. The system receives variable-length status change information frames fed back aperiodically via the simulated DCU module through the Ethernet dual-network channel, or periodically fed back the second uplink DCU information and the second downlink DCU information corresponding to each platform door, and forwards them to the integrated platform door controller through two CAN bus physical channels. The second uplink DCU information includes the status information frame and response frame in the uplink direction of the platform door, and the second downlink DCU information includes the status information frame and response frame in the downlink direction of the platform door.

[0077] In this way, the simulated DCU module can communicate periodically with the integrated platform door controller through two CAN physical channels using the CAN2.0B protocol to simulate the up and down movement of the platform door.

[0078] In one embodiment, such as Figure 4 and Figure 6 As shown, the simulated power supply system module communicates with the general hardware interface platform through two Ethernet switches and with the integrated platform gate controller monitoring unit through a serial port (RS485 interface).

[0079] The general-purpose hardware interface platform is specifically used for: Receive clock synchronization request information sent by the integrated platform door controller monitoring unit via serial port; In response to the clock synchronization request, the fixed-length power supply synchronization clock information is sent non-periodically to the simulated power supply system module via the Ethernet dual-network channel; Receive fixed-length power status information frames periodically fed back by the simulated power system module through the Ethernet dual-network channel; The fixed-length power supply time synchronization information and fixed-length power supply status information frames are forwarded to the integrated platform door controller monitoring unit via serial port.

[0080] The simulated IO relay module communicates with the general hardware interface platform through two Ethernet switches and with the integrated platform door controller through the IO hardwire interface. The general-purpose hardware interface platform is specifically used for: It receives fixed-length IO relay input information frames periodically sent by the integrated platform door controller and forwards them to the simulated IO relay module through the Ethernet dual-network channel; It receives fixed-length IO relay output information frames periodically fed back from the simulated IO relay module and forwards them to the integrated platform door controller via the Ethernet dual-network channel.

[0081] The ISCS-like module communicates with the integrated platform door controller monitoring unit via an IO hardwired interface.

[0082] The ISCS-like module is used to receive comprehensive monitoring information sent by the integrated platform screen door controller monitoring unit; the comprehensive monitoring information includes the internal real-time status information of the integrated platform screen door controller, the platform screen door status of the DCU-like module, and the drive information of the IO relay-like module.

[0083] In one embodiment, such as Figure 4 and Figure 7 As shown, the simulated VOBC module communicates with the integrated platform screen door controller via two Ethernet switches. The simulated VOBC module and the integrated platform screen door controller communicate via a dual-network, dual-system protocol using the RSSP-I protocol. The simulated VOBC module is used to send control information to the integrated platform screen door controller using the Railway Signal Safety Protocol (RSSP) and to receive status information from the integrated platform screen door controller.

[0084] In one embodiment, such as Figure 4 and Figure 8 As shown, the simulated CI module communicates with the integrated platform screen door controller via two Ethernet switches. The simulated CI module and the integrated platform screen door controller use the RSSP-I protocol for dual-network, dual-system communication. The simulated CI module and the integrated platform screen door controller periodically exchange platform screen door status-related information using the railway signal safety protocol.

[0085] In one embodiment, such as Figure 4 and Figure 9As shown, the simulated gap detection module communicates with the integrated platform screen door controller via two Ethernet switches, and also via an I / O hardwired interface. The simulated gap detection module and the integrated platform screen door controller use the RSSP-I protocol for dual-network, dual-system communication. The simulated gap detection module is used to send uplink and downlink gap detection status information to the integrated platform screen door controller using railway signal safety protocols, and to receive command and control information from the integrated platform screen door controller.

[0086] In one embodiment, the simulated IBP module and the simulated PSL module are respectively connected to the general hardware interface platform via two Ethernet switches, and are respectively connected to the integrated platform door controller via IO hardwired interfaces.

[0087] It should be noted that the relays used in the simulated IBP module, simulated PSL module, simulated gap detection module, simulated DCU module, and other related application categories are all implemented via I / O hard wiring. The relay hardware wiring and the sequence of relay drivers should strictly adhere to the relay sequence in the driver table provided in the design.

[0088] On the one hand, integrating all simulation modules into the same operation and control display terminal, and using a unified operation and control display interface for operation, control, and display, can improve testing efficiency. When additional external interface simulations are needed, only the corresponding simulation module needs to be added to quickly expand functionality. On the other hand, since the operation and control display terminal 1 uses common basic configuration data when initializing the basic functions of each simulation module, it can effectively reuse common basic configuration data with common attributes, thereby reducing the workload of data configuration and test verification.

[0089] Furthermore, the operation control display terminal 1 and the general-purpose hardware interface platform 2 can work together to implement complete test logic, efficiently coordinating the entire test process and quickly and accurately verifying the correctness of test results. By rationally dividing the hardware interface and Ethernet interface, the test architecture composed of the operation control display terminal 1 and the general-purpose hardware interface platform 2 can highly reproduce the real environment and achieve accurate simulation testing.

[0090] The integrated platform screen door controller simulation system provided in this invention includes: an operation control display terminal, a general-purpose hardware interface platform, and two Ethernet switches. The operation control display terminal has multiple simulation modules, which simulate the logical functions of corresponding core equipment in the urban rail signaling system. The operation control display terminal provides an operation control display interface for the simulation testing process. That is, integrating all simulation modules within the same operation control display terminal and using a unified operation control display interface for operation, control, and display improves testing efficiency. When additional external interface simulations are needed, only the corresponding simulation module needs to be added to quickly expand functionality. The general-purpose hardware interface platform has multiple hardware interfaces. That is, a general-purpose hardware interface platform with multiple hardware interfaces is provided, enabling centralized and unified hardware interface integration testing. The operation control display terminal initializes the basic functions of each simulation module based on read common basic configuration data and the configuration data of each simulation module, and performs simulation testing on the communication process between each simulation module and the integrated platform screen door controller and the integrated platform screen door controller monitoring unit. That is, common basic configuration data with shared attributes can be effectively reused, thereby reducing the workload of data configuration and testing verification. Furthermore, the operation control display terminal and the general hardware interface platform can work together to implement complete test logic, efficiently coordinating the entire test process and quickly and accurately verifying the correctness of test results. The operation control display terminal and the general hardware interface platform are connected via two Ethernet switches for dual-network redundancy. The integrated platform door controller and the integrated platform door controller monitoring unit communicate with the operation control display terminal through two Ethernet switches and with the general hardware interface platform through corresponding hardware interfaces. That is, by rationally dividing the hardware interfaces and Ethernet interfaces, the test architecture formed by the operation control display terminal and the general hardware interface platform can highly replicate the real environment, achieving accurate simulation testing. Therefore, the integrated platform door controller simulation system provided in this embodiment of the invention can perform complete, accurate, and efficient functional testing of the integrated platform door controller.
