[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The signal test system and method of the present application will be described below. Figures 1-3 The signal test system and method of the present application will be described below.

[0035] Figure 1 The present application provides a signal test system, which comprises at least two test platforms 110 and a platform interaction interface 120.

[0036] Each test platform 110 is connected with a vehicle on-board controller (VOBC), each VOBC controls a simulation train corresponding to the test platform 110 connected with the VOBC, and the at least two test platforms are interconnected.

[0037] In this embodiment, one VOBC can realize independent control of one test platform 110, for example, the test platform 110A is used for simulation test of a simulation train a, and the test platform 110B is used for simulation test of a simulation train b, wherein the test platform 110A is connected with VOBC1, the test platform 110B is connected with VOBC2, VOBC1 only controls the running state of the simulation train a, and VOBC2 only controls the running state of the simulation train b.

[0038] In this embodiment, the running state of the simulation train includes vehicle speed, turnout direction on a train operation line, state of a balise on the train operation line, or axle counting occupation or clearing state, etc.

[0039] The platform interaction interface 120 is used for transmitting turnout direction information and balise message information on a train operation line corresponding to a second test platform to a first test platform in the case that a simulation train corresponding to the first test platform travels on the train operation line corresponding to the second test platform, and transmitting axle counting state information of the simulation train corresponding to the first test platform passing through an axle counting section to the second test platform, wherein the first test platform and the second test platform belong to the at least two test platforms 110.

[0040] In this embodiment, the simulation train corresponding to the test platform 110 can run on the train operation line, or can run on the train operation line corresponding to other test platforms 110, but the VOBC corresponding to the test platform 110 has only control right to the running state of the simulation train corresponding to the test platform 110, and the interaction information is transmitted between the test platforms 110 through the platform interaction interface 120 to realize real-time monitoring of the train running on the train operation line corresponding to different platforms.

[0041] In this embodiment, one platform interaction interface 120 is corresponding to any two test platforms 110, when the simulation train corresponding to the test platform 110 runs on the train operation line corresponding to other test platforms 110, the other test platforms 110 can send the turnout state, balise message information and the like on the train operation line to the platform through the platform interaction interface 120; the platform can inform the other test platforms of the axle counting state of the simulation train on the train operation line corresponding to the other platform, so as to realize information interaction between different test platforms 110.

[0042] The signal test system of the embodiment of the application realizes independent control of each VOBC on the simulation train corresponding to each test platform, and the platform interaction interface is arranged to ensure information interaction between different test platforms and support signal system test, thereby reducing the development and debugging workload of the adaptation software of the manufacturer and improving the signal system test efficiency.

[0043] In some embodiments, each test platform 110 comprises: a train simulation module, the train simulation module being used to provide a simulation train and a train operation line; and an interlocking trackside device simulation module, the interlocking trackside device module being used to monitor the turnout opening direction information, balise message and axle counting state information corresponding to the simulation train running on the train operation line.

[0044] In this embodiment, the interlocking trackside device module can adopt the existing implementation mode of each manufacturer, such as relay, Ethernet axle counting and full electronic, and the principle of independent control of the simulation train in the train simulation module mainly includes the following scenes:

[0045] (1) The VOBC of each manufacturer runs on the train line of the manufacturer;

[0046] In this case, the train is directly monitored by the VOBC on the train operation state, and information interaction is not needed between different test platforms.

[0047] (2) The simulation train a of the test platform of the A manufacturer runs on the train operation line c of the test platform of the B manufacturer;

[0048] The simulation train needs to travel according to a predetermined path on the line, and the path is determined by the opening of the turnout, and the test platform of the B manufacturer needs to inform the test platform of the A manufacturer of all the turnout states of the line of the B manufacturer, so that the simulation train a can travel along the predetermined path when traveling on the running line c (the test platform of the A manufacturer contains the electronic map corresponding to the running line c).

[0049] (2) During the travel of the simulation train a on the running line c, the balise message passed by the simulation train is sent to the ATP (Automatic Train Protection, train automatic protection subsystem). The passive balise can be pre-configured by the test platform of the A manufacturer, but the message of the active balise is variable, and the test platform of the B manufacturer needs to inform the test platform of the A manufacturer of all the active balise messages of the running line c, so that the simulation train a sends the message to the ATP according to the actual selection of the running line c when traveling on the running line c.

[0050] (3) During the travel of the simulation train a on the running line c, the occupation or clearing of the axle counting section on the running line c will be triggered, and the test platform of the A manufacturer needs to inform the occupation of the axle counting of the simulation train a on the running line c, so that the test platform of the B manufacturer sends the occupation information to the CI.

[0051] The signal test system of the embodiment of the application analyzes the train control right and obtains core information related to testing as interactive information between platforms by setting the train simulation module and the interlocking trackside equipment simulation module, fully utilizes the existing mature function modules, and avoids other problems caused by large-scale modification.

[0052] In some embodiments, the signal test system further comprises a VOBC interface and a CI interface, wherein the VOBC interface is used for data interaction between the at least two test platforms 110 and the corresponding VOBC, and the CI interface is used for data interaction between the at least two test platforms 110 and the corresponding CI.

[0053] In this embodiment, the test platform 110 establishes a communication connection with the VOBC through the VOBC interface to realize data interaction; for example, the test platform 110 sends the pulse signal corresponding to the train travel speed to the VOBC, or sends the balise message data to the VOBC, and can also send the I / O output information (train door opening and closing state or train acceleration and deceleration, etc.) to the VOBC.

[0054] In this embodiment, the test platform 110 establishes a communication connection with the interlocking through the CI (Computer Interlocking, interlocking) interface; for example, the test platform 110 interacts with the interlocking through the relay.

[0055] Figure 2 This is the second schematic diagram of the signal testing system provided by the present invention. Figure 2 In the illustrated embodiment, test platform A (corresponding to test platform-A) interacts with the VOBC of the test object A through the VOBC interface and with the interlock through the CI interface. Similarly, test platform B (corresponding to test platform-B) interacts with the VOBC of the test object B through the VOBC interface and with the interlock through the CI interface. Furthermore, there is an information exchange process between test platform-A and test platform-B.

[0056] The signal testing system of this invention establishes communication connections with real-world VOBV and CI by setting up VOBC and CI interfaces respectively, thereby improving the signal system testing process.

[0057] The signal testing system provided by the present invention is described below. The signal testing system described below can be referred to in correspondence with the signal testing method described above.

[0058] Figure 3 This is a flowchart illustrating the signal testing method provided by the present invention, as shown below. Figure 3 As shown, this signal testing method includes the following steps:

[0059] Step 310: With at least two test platforms interconnected, acquire the turnout direction information, transponder message information and axle count status information recorded by each test platform. Each test platform is connected to an on-board controller (VOBC), and each VOBC controls a simulated train corresponding to a test platform connected to the VOBC.

[0060] In this step, each test platform corresponds to a Vehicle On-Board Controller (VOBC), and each VOBC controls a simulated train corresponding to one test platform.

[0061] In this embodiment, an on-board controller (VOBC) can independently control a test platform. For example, test platform A is used for simulation testing of train type a, and test platform B is used for simulation testing of train type b. Test platform A is connected to VOBC1, and test platform B is connected to VOBC2. VOBC1 only controls the operating status of the simulated train a, and VOBC2 only controls the operating status of the simulated train b.

[0062] In this embodiment, the operating status of the simulated train includes the train speed, the direction of the switches on the train route, the status of the transponders on the train route, or the occupancy or clearing status of the axle counters, etc.

[0063] In step 320, the turnout opening direction information and balise message information on the train operation line corresponding to the second test platform are transmitted to the first test platform, and the axle counting state information of the simulated train passing through the axle counting section corresponding to the first test platform is transmitted to the second test platform, so as to perform signal testing by the first test platform and the second test platform. The first test platform and the second test platform belong to at least two test platforms.

[0064] In this step, a platform interaction interface can be arranged between the two test platforms. The platform interaction interface is used to receive the turnout opening direction information and balise message information sent by the second test platform through the platform interaction interface when the simulated train corresponding to the first test platform runs on the train operation line corresponding to the second test platform, so as to ensure the normal operation of the train. The second test platform receives the axle counting state information sent by the first test platform through the platform interaction interface. The purpose is to inform the interlocking of the second test platform of the axle counting occupation caused by the train.

[0065] In this embodiment, the simulated train corresponding to the test platform can run on the train operation line corresponding to the test platform or on the train operation line corresponding to other test platforms. However, the VOBC corresponding to the test platform has only control right for the running state of the simulated train corresponding to the test platform. The platform interaction interfaces are arranged between the test platforms to realize real-time monitoring of the train running on the train operation line corresponding to different test platforms.

[0066] In this embodiment, a platform interaction interface is arranged between any two test platforms. When the simulated train corresponding to the test platform runs on the train operation line corresponding to other test platforms, the other test platforms can send the turnout state and balise message information on the train operation line to the test platform through the platform interaction interface. The test platform can inform the other test platforms of the axle counting occupation state of the simulated train on the train operation line corresponding to the other test platforms, so as to realize information interaction between different test platforms.

[0067] The signal testing method of the embodiment of the application realizes independent control of each VOBC on the simulated train corresponding to each test platform, and the platform interaction interfaces are arranged to realize information interaction between different test platforms and support signal system testing. The workload of the adaptation software development and debugging of manufacturers is reduced, and the signal system testing efficiency is improved.

[0068] In some embodiments, each test platform stores the turnout index, active balise index and axle counting index of the simulated train corresponding to the test platform.

[0069] In this embodiment, the turnout index content can be set according to user requirements, for example, the turnouts on the train route can be numbered according to the route from the starting point to the end point, and the train route has n turnouts, each turnout index has a length of 2 bytes, and the opening direction of each turnout can be set by the following numbers: 0x55 represents the turnout positioning, 0xAA represents the turnout reverse positioning, and 0xCC represents the turnout four opening.

[0070] In this embodiment, the active transponder index content can be set according to user requirements, for example, the number of active transponders set on the train route is m, and the active transponder message corresponds to m transponders; the active transponder index content includes the number of active transponders (2 bytes, indicating the number of all active transponders m on the line), and the length of the m active transponder messages is 128 bytes, corresponding to the decoded message of 1023 bits.

[0071] In this embodiment, the axle counter index content can be set according to user requirements; for example, the number of axle counters set on the train route is k, and each axle counter corresponds to an axle counter state, so that a total of k axle counter states are counted; the axle counter index content includes: the number of axle counters (2 bytes, indicating that a total of k axle counters are counted on other test platforms), each axle counter state occupies 1 byte, and the axle counter state includes clearing and occupation, wherein the clearing state of the axle counter is represented by 0xBB, and the occupation state is represented by 0x66.

[0072] The signal test method of the embodiment of the application can flexibly set and test the core information based on the train model by storing the turnout index, the active transponder index and the axle counter index on each test platform.

[0073] In some embodiments, the sequence of the turnout index between at least two test platforms is consistent, the sequence of the active transponder index between at least two test platforms is consistent, and the sequence of the axle counter index between at least two test platforms is consistent.

[0074] In this embodiment, when the simulation train of the test platform runs on the line of other test platforms, the message information generated by the train passing through the transponder or the opening direction of the turnout on the running route needs to be sent to the test platform by other test platforms, and the axle counter occupation state of the simulation train on the running line also needs to be sent to other test platforms, and in this process, since the test platforms all store the turnout index, the active transponder index and the axle counter index, and the sequence of the turnout index between two test platforms is consistent, the sequence of the active transponder index between two test platforms is consistent, and the sequence of the axle counter index between two test platforms is consistent, only the length or the information of the corresponding index needs to be sent, and the turnout ID, the active transponder ID and the axle counter ID can be added without simplifying the communication content.

[0075] The signal test method of the embodiment of the present application can reduce the information interaction content between the test platforms and improve the information transmission efficiency by keeping the turnout index consistent between the at least two test platforms, keeping the active transponder index sequence consistent, and keeping the axle counter index sequence consistent.

[0076] In some embodiments, the state information of the axle counter includes occupancy information or clearance information of the axle counter, the turnout opening direction information and the transponder message information of the train operation line corresponding to the second test platform are transmitted to the first test platform, and after the state information of the axle counter in the axle counter section through which the simulated train corresponding to the first test platform passes is transmitted to the second test platform, the method further includes: obtaining actual clearance information of the axle counter based on the clearance information of the axle counter and the train clearance information corresponding to the second test platform; or obtaining actual occupancy information of the axle counter based on the occupancy information of the axle counter and the train occupancy information corresponding to the second test platform.

[0077] In this embodiment, when the simulated train a on the test platform A drives on the operation line c on the test platform B, the test platform A and the test platform B perform information interaction through the platform interaction interface, and the test platform B can receive the axle counter clearance information sent by the test platform A, at this time, the axle counter occupancy information of the train a on the line needs to be comprehensively judged in combination with the axle counter clearance information sent by other test platforms and the occupancy of the train on the B side.

[0078] In some embodiments, only the axle counter state information sent by other test platforms cannot accurately predict the train occupancy or clearance on the train operation line of the test platform.

[0079] The signal test method of the embodiment of the present application can comprehensively judge the axle counter occupancy / clearance when the train runs by combining the axle counter occupancy / clearance information sent by other test platforms and the train occupancy / clearance on the operation line of the test platform, thereby improving the accuracy of the axle counter occupancy / clearance judgment.
