[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] At present, there are two main simulation methods for the all-electronic computer interlocking system. One is to use a PC to simulate the CAN data of the all-electronic board and send it to the host module of the all-electronic interlocking system. This method cannot test and verify the actual configuration on site, and the data flow is inconsistent with the actual application. The other is to use the same CAN module as the on-site ratio for simulation. This method can realize the test and verification of the actual configuration on site and the data flow, but the scalability and flexibility are poor. To this end, the present application provides a simulation test for a full-electronic computer interlocking system, which can improve the reliability and flexibility of the simulation test of the full-electronic computer interlocking system.

[0053] In the simulation test scheme of the fully electronic computer interlocking system of this application, the system framework used can be found in Figure 1 As shown, it may specifically include a fully electronic logic control host 01 , a communication plug-in 02 and a fully electronic simulation machine 03 .

[0054] Specifically, for the communication plug-in 02, it should be noted that the CAN interface of the communication plug-in 02 is connected to the full electronic logic control host 01, and the Socket interface of the communication plug-in 02 is connected to the full electronic simulator 03. Among them, the communication plug-in 02 includes a communication configuration component, a CAN-Socket protocol conversion component, and a fault injection component. Through the communication configuration component, communication configuration can be performed in the communication plug-in, so that the communication configuration of the full electronic logic control host includes but is not limited to the CAN number, CAN communication quantity, baud rate, communication mode, etc. For the CAN-Socket protocol conversion component, the CAN-Socket protocol conversion component can realize protocol conversion between CAN data and Ethernet data, that is, the communication plug-in 02 and the full electronic logic control host 01 use the CAN protocol to communicate, and the communication plug-in 02 and the full electronic simulator 03 use the Sockte protocol to communicate. For the fault injection component, the fault injection component can query in the preset fault type mapping table according to the CAN communication fault instruction issued by the human-machine interface in the full electronic simulator 03, and transmit the corresponding fault information to the full electronic logic control host 01 through the CAN communication method.

[0055] The fully electronic simulator 03 includes an execution unit simulation component, a trackside equipment simulation component, a fault selection component, and a human-machine interface. The execution unit simulation component can simulate the running state of the fully electronic board. It receives the control signal parameters in the Socket frame format sent by the communication plug-in 02, and converts the control signal parameters into control signal instructions, and then simulates the driving instructions of the fully electronic board according to the control signal instructions; and simulates the response and recovery state of the fully electronic board according to the driving instructions, and feeds back the executed device status signal to the communication plug-in 02 through the device status signal parameters in the Socket frame format. At the same time, fault injection of the fully electronic board can also be performed.

[0056] The trackside equipment simulation component is used to simulate the operating status of the trackside equipment. It receives control instructions from the execution unit simulation component, simulates the operating status of the trackside equipment according to the control instructions, and displays the operating status of the trackside equipment in the human-machine interface of the full electronic simulator 03. In addition, the operating status of the trackside equipment will be fed back to the execution unit simulation component, or receive control commands from the human-machine interface, simulate the operating status of the trackside equipment, and feed the operating status of the trackside equipment back to the execution unit simulation component. At the same time, fault injection of the trackside equipment can be performed.

[0057] As for the human-machine interface, the human-machine interface is used to display the operating status of the full electronic board simulated by the execution unit simulation component and the operating status of the trackside equipment simulated by the trackside equipment simulation component, and can modify the operating status of the full electronic board simulated by the execution unit simulation component and the operating status of the trackside equipment simulated by the trackside equipment simulation component, and display the status and mismatch information of the communication link between the full electronic logic control host 01 and the communication plug-in 02 and the full electronic simulation machine 03, and display the CAN communication fault instruction option.

[0058] See also Figure 2 As shown, the embodiment of the present invention discloses a simulation test method for a fully electronic computer interlocking system, comprising:

[0059] Step S11, add a communication plug-in in the all-electronic computer interlocking system, the CAN end being connected to the all-electronic logic control host and the Socket end being connected to the all-electronic simulation machine, and configure the communication plug-in based on the all-electronic IO (i.e., Input / Output) allocation table; the all-electronic IO allocation table is a table containing the point information of the all-electronic board and the communication address corresponding to the all-electronic board.

[0060] In this embodiment, the all-electronic IO allocation table covers important contents such as the position information of the all-electronic boards and the communication addresses corresponding to each all-electronic board. The position information of the all-electronic boards specifies the location of key nodes such as signal input or output in the system on specific boards, such as the signal points on the turnout board that control the action of the turnout switch machine, and the points on the signal board that correspond to different light display controls. The communication addresses corresponding to the all-electronic boards enable the corresponding data to accurately find the corresponding all-electronic boards in the entire all-electronic computer interlocking system, thereby realizing efficient information transmission.

[0061] Therefore, it can be understood that the data receiving source, the first destination IP address and the first port number for communicating with the all-electronic simulation machine are configured for the Socket end of the communication plug-in based on the all-electronic IO allocation table. Specifically, the determination of the first destination IP address is the specific location identifier of the all-electronic simulation machine in the network, and different port numbers correspond to different functional components on the all-electronic simulation machine. The first port number is configured to ensure that the data can accurately enter the corresponding processing flow.

[0062] At the same time, the CAN number is configured for the CAN end of the communication plug-in based on the all-electronic IO allocation table. It should be noted that the CAN number is unique in the CAN communication network of the entire all-electronic computer interlocking system, and it can accurately distinguish different communication links and different device connections. Therefore, each related device has a different CAN number. When the CAN end of the communication plug-in is configured with an accurate CAN number, it can be accurately integrated into the entire CAN communication network and communicate with the all-electronic logic control host accordingly.

[0063] Step S12, configuring the fully electronic simulation machine based on the fully electronic IO allocation table and the fully electronic cabinet assembly to obtain a configured fully electronic simulation machine; the fully electronic cabinet assembly is a collection of fully electronic cabinets, each of which contains information on fully electronic boards.

[0064] Similarly, in this embodiment, not only the communication plug-in needs to be configured, but also the full electronic simulation machine needs to be configured. For the configuration of the full electronic simulation machine, specifically, the data receiving source, the second destination IP address and the second port number for communicating with the communication plug-in are configured for the Socket end of the full electronic simulation machine based on the full electronic IO allocation table.

[0065] At the same time, based on the full electronic cabinet assembly, the cabinet number, group box number, board number and communication address corresponding to the CAN number of the full electronic board are configured for the full electronic simulation machine. Among them, since each full electronic cabinet contains the information of the full electronic board, the cabinet number, group box number and board number corresponding to the full electronic board can be configured according to the full electronic cabinet assembly. Specifically, the determination of the cabinet number enables the full electronic simulation machine to logically correspond to the actual physical cabinet layout and clarify the cabinet location of each board. The configuration of the group box number further refines the location information of the board, which is convenient for rapid positioning and management of the board. The setting of the board number gives each board a unique identity, which can be accurately identified and controlled in the entire system.

[0066] Step S13: When the communication link between the all-electronic logic control host, the communication plug-in and the configured all-electronic simulation machine has been successfully established, the control command issued by the system host computer is obtained through the all-electronic logic control host.

[0067] It should be noted that in this embodiment, in the simulation test process of the all-electronic computer interlocking system, the successful establishment of the communication link is the prerequisite for ensuring the smooth implementation of subsequent tests and operations. Therefore, after completing the corresponding configuration of the communication plug-in and the all-electronic simulator, it is first necessary to judge the communication link status between the all-electronic logic control host, the communication plug-in and the configured all-electronic simulator.

[0068] If the communication link between the three is successfully established, it means that the communication architecture of the system has been initially built and has the basic conditions for receiving and executing instructions. At this point, the fully electronic logic control host can obtain the control commands issued by the system host computer.

[0069] However, when the communication link between the all-electronic logic control host, the communication plug-in, and the configured all-electronic simulation machine is not successfully established, the communication link is not established icon is displayed in the human-machine interface of the all-electronic simulation machine, indicating that the communication configuration information between the all-electronic logic control host and the communication plug-in does not match, and the mismatch information is displayed, and the step of configuring the communication plug-in based on the all-electronic IO allocation table is jumped again until the communication link is successfully established. It is understandable that when the communication link is not successfully established, this indicates that there may be a problem with the current configuration. At this time, in order to ensure that the system can operate normally, it is necessary to immediately jump back to the step of configuring the communication plug-in based on the all-electronic IO allocation table.

[0070] Step S14: convert the first control signal parameter generated by the full electronic logic control host based on the control command into the second control signal parameter through the communication plug-in; the first control signal parameter and the second control signal parameter meet the communication protocol requirements of the CAN end and the Socket end respectively.

[0071] In this embodiment, when the all-electronic logic control host successfully obtains the control command issued by the system host computer, the system enters the simulation test phase. It should be noted that in the simulation test phase, the communication plug-in module communicates with the all-electronic logic control host using the CAN_FD (i.e., CAN with Flexible Data Rate, controller area network flexible data rate) protocol, and the communication plug-in module communicates with the all-electronic simulation machine using the Socket protocol.

[0072] It is understandable that, in the simulation test phase, after the system host sends a control command, the control command is converted into a first control signal parameter based on a preset logic algorithm through the fully electronic logic control host, and the first control signal parameter is sent to the communication plug-in. Among them, the first control signal parameter is a parameter in the CAN frame format, and the first control parameter matches the communication protocol of the CAN end.

[0073] Furthermore, in this embodiment, the first control signal parameter is converted into the second control signal parameter based on the preset CAN-Socket protocol by the communication plug-in, so as to send the second control signal parameter to the configured all-electronic simulator. That is, the communication plug-in receives the first control signal parameter from the all-electronic logic control host, and converts the first control signal parameter into the second control signal parameter that complies with the Socket end communication protocol according to the preset CAN-Socket protocol. In this conversion process, the communication plug-in needs to adjust the data in the first control signal parameter to obtain the second control signal parameter in the Socket format.

[0074] Step S15, after configuration, the fully electronic simulation machine determines the corresponding control signal instruction based on the second control signal parameter, and simulates the operating status of the fully electronic board and the trackside equipment based on the control signal instruction.

[0075] In this embodiment, after the communication plug-in sends the converted second control signal parameter to the configured all-electronic simulator, the configured all-electronic simulator converts the second control signal parameter to obtain the corresponding control signal instruction. Further, the operating state of the all-electronic board and trackside equipment is simulated using the control signal instruction to obtain a simulated operating state. Specifically, for all-electronic boards, such as turnout boards, signal boards, track circuit boards, scattered boards, and IO boards, etc., their working states in the actual railway signal interlocking system are simulated according to the control signal instruction. At the same time, for trackside equipment, such as actual turnouts, signal machines, track circuits, etc., the operating state can also be simulated based on the control signal instruction. In addition, in this simulation process, the all-electronic simulator needs to comprehensively consider various factors and conditions, such as the collaborative working relationship between different boards, the signal interaction mechanism between trackside equipment and boards, and the state change law of the system in different operating stages, so as to obtain a simulated operating state that truly reflects the operating conditions of the system. In addition, the simulated operating state of the all-electronic board and trackside equipment will be displayed in the human-machine interface of the all-electronic simulator.

[0076] Subsequently, in order to construct a complete signal feedback loop and perform subsequent processing, the fully electronic simulator converts the simulated operation state into a first state signal parameter through configuration, and sends the first state signal parameter to the communication plug-in, converts the first state signal parameter into a second state signal parameter through the communication plug-in, and sends the second state signal parameter to the fully electronic logic control host. Among them, the first state signal parameter and the second state signal parameter meet the communication protocol requirements of the CAN end and the Socket end respectively.

[0077] As can be seen from the above, the present application adds a communication plug-in to the fully electronic computer interlocking system and configures it according to the fully electronic IO allocation table, which contains the fully electronic board point information and the corresponding communication address. Based on this table and the fully electronic cabinet assembly, the fully electronic simulation machine is configured to obtain a configured simulation machine. If the communication link between the fully electronic logic control host, the communication plug-in and the configured simulation machine is successful, the fully electronic logic control host receives the control command of the system host computer, and the communication plug-in converts the first control signal parameter generated by the host according to the command into a second control signal parameter that complies with the Socket end protocol. The configured simulation machine determines the control signal instruction accordingly to simulate the operating status of the fully electronic board and the trackside equipment. In this way, the present application can effectively improve the reliability and flexibility of the simulation test of the fully electronic computer interlocking system, thereby improving the user experience.

[0078] See also Figure 3 As shown, in order to realize the fault injection of the all-electronic logic control host, the embodiment of the present application further provides a specific all-electronic computer interlocking system simulation test method, including:

[0079] Step S21: construct a preset fault type mapping table based on the CAN communication fault type, and save the preset fault type mapping table to the communication plug-in.

[0080] In this embodiment, the construction of the preset fault type mapping table requires the study of various CAN communication fault conditions that may occur in the fully electronic computer interlocking system. These fault types may cover a variety of situations such as short circuit, open circuit, signal interference, data transmission error, etc. of the communication line, and each fault type may have different degrees of impact on the normal operation of the system. By analyzing and classifying these fault types in detail, they are associated with the corresponding fault information to form a preset fault type mapping table.

[0081] After the construction is completed, this preset fault type mapping table is saved in the communication plug-in. The communication plug-in serves as a key communication bridge between the all-electronic logic control host and the all-electronic simulator, which can ensure that the fault information corresponding to the target fault instruction is accurately obtained during the subsequent fault injection test.

[0082] Step S22: When the target communication fault instruction is selected through the full electronic simulation machine, the target communication fault instruction is sent to the communication plug-in based on the Socket communication method.

[0083] When performing fault injection, the operator can select the target communication fault instruction on the operation interface provided by the full electronic simulator according to specific needs. Once the target communication fault instruction is selected, and because the data transmission between the communication plug-in and the full electronic simulator needs to be carried out through the Socket method, the full electronic simulator will send the target communication fault instruction to the communication plug-in based on the Socket communication method after configuration.

[0084] Step S23: query the fault information corresponding to the target communication fault instruction from the preset fault type mapping table through the communication plug-in, and transmit the fault information to the full electronic logic control host based on the CAN communication method.

[0085] In this embodiment, after receiving the target communication fault instruction issued by the fully electronic simulator, the communication plug-in will search and match in the preset fault type mapping table to query the fault information corresponding to the target communication fault instruction. Once the corresponding fault information is found, the communication plug-in will convert the fault information into a data packet format suitable for transmission in the CAN communication mode according to the communication protocol requirements of the fully electronic computer interlocking system, and transmit the fault information to the fully electronic logic control host through its CAN end.

[0086] Step S24: The fault information is identified by the fully electronic logic control host, and the obtained identification result is used to display the fault information accordingly in the system host computer to complete the fault injection of the fully electronic logic control host.

[0087] After receiving the fault information transmitted by the communication plug-in, the fully electronic logic control host immediately starts its internal fault identification program to identify the fault information accordingly. After completing the fault identification, the fully electronic logic control host will transmit the identification results to the system host computer through the communication link inside the system, and the system host computer can display the received fault information to a certain extent. The operator can understand the fault situation of the system in real time through the display interface of the host computer, and perform corresponding processing and decision-making according to the preset emergency plan and operating procedures, thereby completing the fault injection of the fully electronic logic control host.

[0088] As can be seen from the above, the present application constructs a preset fault type mapping table, selects the target communication fault instruction on the all-electronic simulation machine, and sends the target communication fault instruction to the communication plug-in through the Socket communication method, so that the communication plug-in queries the corresponding fault information according to the preset fault type mapping table, so as to transmit the fault information sent by the communication plug-in to the system host computer through the all-electronic logic control host, thereby realizing the fault injection of the all-electronic logic control host in the all-electronic computer interlocking system. This enables the system to expose potential problems during the simulation test phase. In this way, the present application provides a solid guarantee for the safe and stable operation of the all-electronic computer interlocking system, and effectively reduces the safety risks and the possibility of operation interruption caused by faults.

[0089] Accordingly, see Figure 4 As shown, the embodiment of the present application provides a full electronic computer interlocking system simulation test device, comprising:

[0090] The plug-in configuration module 11 is used to add a communication plug-in in the all-electronic computer interlocking system, the CAN end being connected to the all-electronic logic control host and the Socket end being connected to the all-electronic simulation machine, and to configure the communication plug-in based on the all-electronic IO allocation table; the all-electronic IO allocation table is a table containing the point information of the all-electronic board and the communication address corresponding to the all-electronic board;
