[0041] To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all of the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0042] In addition, the term "and / or" herein merely describes an associated relationship between associated objects, indicating that there can be three relationships, for example, A and / or B, which can represent three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0043] The full electronic computer interlocking system (Full electronic computer interlocking) is a new generation of computer interlocking system. The object controller (Object controller) is a sub-module of the full electronic interlocking system and is an execution unit of the interlocking. The traditional relay combination is miniaturized, on-board, and electronic, integrated on each control type board card, and the state of the outdoor signal equipment is collected and controlled commands are output externally.

[0044] The interlocking system is the most basic guarantee for safe and efficient train operation. The execution unit of the full electronic interlocking replaces the traditional relay interface, and the collection and driving of the signal equipment are realized by electronic devices. In the code variable layer of logical operation, the aging of electronic devices and environmental changes can easily affect the jump of the collection value. In the case of coincidence in many cases, the operation result is output to the signal equipment, which may cause danger. Therefore, the test must include the collection and driving of the real equipment, and the simulation software cannot be directly used to simulate the input and output.

[0045] The full electronic interlocking test platform is an environment built entirely by simulation software, mainly used for developers to debug and analyze problems. During indoor integrated testing, a real full electronic interlocking test platform needs to be built, including real cabinets, execution units using real OC cabinets, trackside devices using simulation trackside to simulate (using simulation IO to bridge the signal equipment state of the trackside to the simulation tooling, OC collecting the point position on the simulation tooling, and only one real device for each signal and switch machine), and local workstations.

[0046] During indoor integrated testing or engineering indoor testing, a complete test platform composed of real devices cannot be completely built, mainly due to the limitation of OC. Because there are not enough board cards to support the collection and driving of the input and output of each station during the testing phase, and when a fault occurs in a certain board card of the OC cabinet, the entire interlocking centralized area cannot be tested.

[0047] In summary, in the existing test scheme, a complete test platform cannot be built.

[0048] In the present disclosure, an electronic interlocking simulation test method, system, device and storage medium are provided. The OC execution board is simulated by using simulation execution board software to meet the processing requirements of the device deployed by the wayside device simulation software and the host device, solve the problem that the number of board cards in the OC cabinet is not enough or fails to build a complete test platform, and realize remote connection of the host device and the device deployed by the wayside device simulation software based on the data conversion function between the CAN FD data and the Ethernet data of the data conversion device. Therefore, based on simulation software simulation and Ethernet long-distance communication, a reliable and stable test platform can be built.

[0049] The technical solutions provided by the embodiments of the present disclosure are described below with reference to the drawings.

[0050] Figure 1 is a structural block diagram of an electronic interlocking simulation test system provided by an embodiment of the present disclosure, as Figure 1 shown, the electronic interlocking simulation test system can specifically include:

[0051] The host device 101 is configured to send a control signal to the device 105 deployed by the wayside device simulation software through the data conversion device.

[0052] The data conversion device 102 is configured to receive the control signal in the Ethernet frame format sent by the host device based on the data conversion between the CAN FD data and the Ethernet data, and send the control signal in the Ethernet frame format to the device deployed by the simulation execution board software through the switch 103.

[0053] The device 104 deployed by the simulation execution board software is configured to convert the control signal into a first target signal meeting the processing requirements of the wayside device simulation software, and send the first target signal to the device 105 deployed by the wayside device simulation software, so that the wayside device simulation software simulates the corresponding function according to the target signal.

[0054] The device 104 deployed by the simulation execution board software is further configured to receive a state signal in the Ethernet frame format fed back by the device deployed by the wayside device simulation software after simulating the function, convert the state signal into a second target signal meeting the processing requirements of the host device, and send the second target signal to the data conversion device through the switch 103.

[0055] The data conversion device 102 is further configured to convert the second target signal into a third target signal in the CAN FD frame format based on the data conversion between the CAN FD data and the Ethernet data, and send the third target signal to the host device, so that the host device analyzes the third target signal.

[0056] Because in the electronic interlocking simulation test system in the present disclosure, the OC execution board can use simulation software for simulation, the problem that the number of board cards in the OC cabinet is insufficient or fails to cause a complete test platform to be built is solved, and the main control equipment and the simulation software deployed equipment of the wayside equipment communicate through Ethernet to ensure the stability of long-distance communication. Therefore, based on simulation software simulation and Ethernet long-distance communication, a reliable and stable test platform can be built.

[0057] Figure 2 is a flowchart of an electronic interlocking simulation test method provided by an embodiment of the present disclosure, which is implemented based on the test system in Figure 1

[0058] As shown in Figure 2 , the electronic interlocking simulation test method can include two-way data transmission, i.e., the main control equipment sends signals to the simulation software deployed equipment of the wayside equipment and the simulation software deployed equipment of the wayside equipment sends signals to the main control equipment, which can specifically include:

[0059] S201: using a data conversion device, based on data conversion between CAN FD data and Ethernet data, receiving an Ethernet frame format control signal sent by the main control equipment, and sending the Ethernet frame format control signal to the simulation execution board software deployed equipment through a switch.

[0060] S202: based on the simulation execution board software deployed equipment, converting the control signal into a first target signal meeting the processing requirements of the wayside equipment simulation software, and sending the first target signal to the simulation software deployed equipment of the wayside equipment, so that the wayside equipment simulation software simulates the corresponding function according to the target signal.

[0061] S203: based on the simulation execution board software deployed equipment, receiving an Ethernet frame format state signal fed back by the simulation function executed by the simulation software deployed equipment of the wayside equipment, converting the state signal into a second target signal meeting the processing requirements of the main control equipment, and sending the second target signal to the data conversion device through the switch.

[0062] S204: using the data conversion device, based on data conversion between CAN FD data and Ethernet data, converting the second target signal into a CAN FD frame format third target signal, and sending the third target signal to the main control equipment for analysis by the main control equipment.

[0063] ​Because in the electronic interlocking simulation test method provided in the present disclosure, the OC execution board can use simulation software for simulation, the problem that the number of board cards in the OC cabinet is insufficient or a fault occurs to cause a complete test platform to be unable to be built is solved. Moreover, the inventor considers that the CAN FD communication mode has the problem of being unable to communicate remotely and can only communicate at close range, but actual situation tests are rarely performed near the cabinet, so the device deployed by the simulation software of the host device and the wayside device communicates remotely through Ethernet to ensure the stability of remote communication. Therefore, based on simulation software simulation and Ethernet remote communication, a reliable and stable test platform can be built for testing before the program is run on actual devices.

[0064] In addition, because the present solution is in the initial stage when the program is just written and has not been tested, the test method of the present disclosure can be performed in a laboratory or studio, and the wayside device can be replaced by simulation software, but in the actual environment test process, the wayside device is the real device in the test site.

[0065] It needs to be further explained that the wayside device simulated by the simulation software of the wayside device can be a turnout, a signal machine and the like. Corresponding to the turnout, the signal machine and the like, the simulation execution board software can simulate a turnout board, a signal machine board and the like, for converting the data format that the wayside device can process and the data format that the host device can process, such as analog-digital conversion and the like.

[0066] In one embodiment, in order to ensure the timeliness and safety of the control signal in the form of an Ethernet frame format sent by the host device in S201, the process of receiving the control signal in the form of an Ethernet frame format sent by the host device in S201 can be specifically using a data conversion device to receive the control signal in the form of a CAN FD frame format sent by the host device; then adding an SFP protocol header, an Ethernet header and an Ethernet trailer in the control signal in the form of a CAN FD frame to generate the control signal in the form of an Ethernet frame format.

[0067] In combination with Figure 3 , in the specific process of generating the control signal in the form of an Ethernet frame format, the control signal in the form of a CAN FD frame format can include pillow information, a frame ID and frame information, then the SFP protocol header is added in the frame information, and finally the Ethernet header and the Ethernet trailer are added to generate the control signal in the form of an Ethernet frame format.

[0068] In a specific example, through the inventor's actual test, the communication cycle of the interlocking host and the master device (host board) is 300 ms, and the host board has a window period for receiving data, that is, the data is received within 40 ms, and if the time exceeds this period, packet loss or incomplete reception may occur. In the present disclosure, the control signal in the Ethernet frame format sent by the host board has an SFP protocol header, and the frame format is as shown in Figure 3 The device deployed by the simulation execution board software stores the received data in the cache area, and the SFP takes out the received data in the two-by-two voting platform processing micro-period, compares the sequence number and identifier contained in the SFP header, and gives the latest one to the application when the data is the same. The data received outside the SFP tolerance period is discarded, thereby ensuring the timeliness and reliability of the data.

[0069] In the above embodiment, the CAN FD data is converted into Ethernet data by using the data conversion device to realize subsequent long-distance transmission through Ethernet, and the use of the SFP protocol can also ensure the reliability and timeliness of the data.

[0070] In addition, in order to ensure the safety of the test system, before receiving the CAN FD frame format control signal sent by the master device, the method comprises: two master devices generate two groups of CAN FD frame format comparison control signals, wherein each group of CAN FD frame format comparison control signals includes two signals; any one of the two master devices compares the two groups of CAN FD frame format comparison control signals generated based on the two-by-two voting method; in the case that the two groups of CAN FD frame format comparison control signals are the same, any one group of CAN FD frame format comparison control signal is taken as the CAN FD frame format control signal. In the present disclosure, by adopting the two-by-two voting data acquisition method, the effects of double system redundancy, data synchronization and voting, and fault self-closing can be realized.

[0071] In the process of S203, because the device deployed with the simulation execution board software and the device deployed with the trackside device simulation software are transmitted through Ethernet, that is, the second target signal sent by the device deployed with the simulation execution board software is only to convert the state signal fed back by the device deployed with the trackside device simulation software in the form of an Ethernet frame into data conforming to the processing requirements of the host device, and the state signal is also in the form of an Ethernet frame, in order to enable the second target signal to be transmitted to the host device in the form of a CAN FD frame, in an embodiment, in S204, a data conversion device can be used to receive the second target signal sent by the device deployed with the simulation execution board software; then in the second target signal, the SFP protocol header, the Ethernet header, and the Ethernet trailer are deleted, and a third target signal in the form of a CAN FD frame is generated. In turn, the Ethernet data fed back by the device deployed with the trackside device simulation software can be converted into a CAN FD frame, so as to realize subsequent transmission of the data fed back by the trackside device simulation software to the host device through CAN FD communication.

[0072] In order to use limited boards to target multiple cases, that is, use a set of simulation execution board software to target multiple test cases, in an embodiment, a test switching request input by a user can be received, wherein the test switching request includes a target trackside device to be tested; then parameters in the simulation execution board software are adjusted according to the test switching request, and a modified simulation execution board software is generated, so as to establish a test link between the host device and the target trackside device based on the modified simulation execution board software. The above modification of the simulation test platform by modifying the parameters of the simulation execution board software can be reused for testing other stations without changing the hard-wired connection in actual application, thereby greatly saving the time of test personnel to build a platform and avoiding the tediousness of changing lines when a test environment is used for testing other stations.

[0073] In addition, in actual operation, there may be a case where an OC cabinet contains a large number of execution boards, at which time the amount of data sent by the host board and each execution board to the data conversion device (CAN box) is large, and therefore the data forwarding capability of the data conversion device needs to be tested, so as to ensure that subsequent testing can be performed normally and the conversion capability of the data conversion device in the actual environment can support normal operation. In an embodiment, a preset test data and a test algorithm can be used to test the conversion capability of the data conversion device, which includes a data amount stress test and a transmission rate stress test, so as to ensure that the host board and the execution board or the simulation execution board software can communicate normally in the case where the execution board in the OC cabinet is fully configured.

[0074] Because the host device communicates with the trackside device simulation software deployed device through Ethernet in the present disclosure, the host device can be connected with multiple simulation execution board software deployed devices to establish a star topology of the host device and the multiple simulation execution board software deployed devices, for realizing the connection of the host device and the multiple simulation execution board software corresponding trackside devices. That is, in the actual test process, the host device can form a star topology with multiple execution board cards to realize long-distance connection test and control of the host device on multiple devices.

[0075] In the electronic interlocking simulation test method provided by the present disclosure, the execution board card lacking in the OC part can use simulation software to realize its function, in addition, the CAN FD to Ethernet data access switch is used to make the host board communicate with the simulation execution board card, to ensure the stability of long-distance communication, and the SFP security redundancy layer protocol is used, to further ensure the timeliness and security of data.

[0076] Moreover, the simulation test platform built uses few board cards to test the collection and driving of real board cards, and the rest of the board cards can all be replaced by simulation execution boards (simulation software), so that after the test platform is built, only the configuration of the simulation execution board software needs to be modified, and the rest of the related parameters or function data packets are replaced, to realize the environment building of different stations, so that a test platform can be built without modifying the hardware circuit and all the board cards required by the interlocking central station, which increases the reusability of the environment and greatly reduces the time of test personnel building the test platform.

[0077] In addition, the test method of the present disclosure can be for the initial version of the program just written, that is, the program that has not been actually verified, and the test method can be for the test method in the laboratory or studio.
