Abstract
Description
Technical Field
[0001] The present application relates to the field of train control technology, and in particular to a method for testing a vehicle-mounted device in a guidance mode, a device for testing a vehicle-mounted device in a guidance mode, an electronic device, a computer-readable storage medium, and a computer program product. Background Art
[0002] Suburban railway is a rail transit system between national railway and urban rail transit. Suburban railway signal system (STCS) can be flexibly configured into Chinese Train Control System Level 2 and Automatic Train Operation (CTCS-2+ATO) with automatic return function, Communication Based Train Control System (CBTC) system or CTCS-2+CBTC multi-mode signal system according to the line operation characteristics. The train control modes of CTCS-2 train control on-board equipment include full monitoring, partial monitoring, guidance, visual driving, shunting, isolation and standby. The guidance mode is a mode in which the train control on-board equipment controls the train according to the maximum speed limit of 40km / h after establishing the guidance route when entering or leaving the station. In the guidance mode, the train control on-board equipment is responsible for monitoring the maximum operating speed of the train, and the driver is responsible for driving the train and making corresponding treatment according to the ground conditions to ensure that the train does not enter the dangerous area.
[0003] For the test of CTCS-2 train control on-board equipment under STCS in the guidance mode, at present, the main method is to send HB code to the on-board equipment, and then determine whether the on-board equipment monitors the train operation according to the speed limit of 40km / h. The driver needs to press the alert button every 50s or 200m. If the driver does not press the alert button, the train continues to run for 60s or 300m, and determine whether the on-board equipment triggers emergency braking, allowing the speed to drop to 0 and controlling the train to stop. And after the driver presses the alert button, determine whether the on-board equipment allows the speed to be restored to 40km / h. According to this process, if one of the judgments is no, it is determined that the CTCS-2 train control on-board equipment under STCS has not passed the test in the guidance mode. If all are judged as yes, it is determined that the CTCS-2 train control on-board equipment under STCS has passed the test in the guidance mode.
[0004] However, the above method can only perform a rough test on the on-board equipment of the CTCS-2 train control under STCS in the guidance mode, but cannot perform an accurate test on the on-board equipment, which increases the safety risk of the on-board equipment and reduces the safety of train operation. Summary of the invention

[0006] In order to solve the above technical problems, the embodiments of the present application provide the following technical solutions:
[0007] A first aspect of the present application provides a testing method for an on-board device in a guidance mode, the method is applied to the on-board device, the on-board device is installed on a train, and the method comprises: sending a first target code to the on-board device, the on-board device is a train control on-board device of CTCS-2 under STCS, and the first target code is used to characterize that the guidance signal is open; judging whether the on-board device generates and displays a fixed mode curve with a ceiling at a preset speed; if so, sending a second target code to the on-board device, the second target code is used to characterize that an abnormality has occurred in the operation of the train; judging whether the on-board device generates and displays a target distance mode curve with a stop at a preset position ahead and a ceiling at a preset speed; if so, determining that the on-board device has passed the test in the guidance mode; if at least one of the two judgments is no, determining that the on-board device has not passed the test in the guidance mode.
[0008] Compared with the prior art, the first aspect of the present application provides a method for testing on-board equipment in a guidance mode, which determines that after the on-board equipment generates and displays a fixed mode curve with a ceiling at a preset speed in the guidance mode, the relevant codes for other driving conditions continue to be input into the on-board equipment, thereby determining whether the on-board equipment can be correctly controlled in various situations encountered in the guidance mode based on the target distance mode curve generated and displayed by the on-board equipment for parking at a preset position ahead and with the ceiling at a preset speed, thereby achieving accurate testing of the on-board equipment in the guidance mode, reducing the safety risks of the on-board equipment, and improving the safety of train operation.
[0009] In some changed implementation modes of the first aspect of the present application, the second target code includes multiple types of codes; sending the second target code to the vehicle-mounted device includes: sending each second target code to the vehicle-mounted device in sequence; judging whether the vehicle-mounted device generates and displays a target distance mode curve for parking at a preset position in front and a preset speed for the roof, including: judging whether the vehicle-mounted device generates and displays a target distance mode curve for parking at a preset position in front and a preset speed for the roof in sequence.
[0010] Inputting the relevant codes under various driving conditions into the on-board device can test the accuracy of the on-board device in handling various driving conditions, increase the test scenarios under the on-board device guidance mode, and realize more accurate testing under the on-board device guidance mode.
[0011] In some modified implementations of the first aspect of the present application, the second target code includes HU code, NULL code, JC code (27.9 Hz) and LOCK code (25.7 Hz).
[0012] Since the HU code, NULL code, JC code (27.9 Hz) and LOCK code (25.7 Hz) can concisely and comprehensively characterize various situations in the guidance mode, using the HU code, NULL code, JC code (27.9 Hz) and LOCK code (25.7 Hz) to test the vehicle-mounted equipment can improve the test efficiency of the vehicle-mounted equipment in the guidance mode.
[0013] In some modified implementations of the first aspect of the present application, before determining whether the on-board device generates and displays a target distance pattern curve for stopping at a preset position ahead and with the roof at a preset speed, the method also includes: controlling the on-board device to obtain a CTCS-1 package from the front transponder; determining whether the on-board device generates and displays a target distance pattern curve for stopping at a preset position ahead and with the roof at a preset speed, including: if the CTCS-1 package is obtained, determining the target signal based on the CTCS-1 package, and determining whether the on-board device generates and displays a target distance pattern curve for stopping at the target signal ahead and with the roof at a preset speed; if the CTCS-1 package is not obtained, determining whether the on-board device generates a fixed pattern curve with the roof at a preset speed and traveling a preset distance.
[0014] Since the on-board equipment controls driving based on the data in the transponder CTCS-1 package, by inputting CTCS-1 packages with different contents into the on-board equipment and generating a speed distance control curve based on the CTCS-1 package by the on-board equipment, it is possible to enrich the test scenarios in the on-board equipment guidance mode and achieve more accurate testing in the on-board equipment guidance mode.
[0015] In some modified implementations of the first aspect of the present application, the target signal is determined based on the CTCS-1 package, and it is determined whether the on-board equipment generates and displays a target distance mode curve for stopping at the target signal ahead and the ceiling at a preset speed, including: when NID_SIGNAL=0 in the CTCS-1 package, it is determined that there is no target signal, and it is determined whether the on-board equipment generates and displays a target distance mode curve for stopping at the insulating joint ahead and the ceiling at a preset speed; when NID_SIGNAL=1 in the CTCS-1 package, it is determined that the target signal is an entry signal, and it is determined whether the on-board equipment generates and displays a target distance mode curve for stopping at the entry signal ahead and the ceiling at a preset speed; when NID_SIGNAL=2 in the CTCS-1 package, it is determined that the target signal is an exit signal without an active transponder, and it is determined whether the on-board equipment generates and displays a target distance mode curve for stopping at the insulating joint ahead and the ceiling at a preset speed. Display the target distance mode curve for stopping at the exit signal without an active transponder in front and the preset speed of the ceiling; when NID_SIGNAL=3 in the CTCS-1 package, determine that the target signal is a through signal, and judge whether the on-board equipment generates and displays the target distance mode curve for stopping at the through signal in front and the preset speed of the ceiling; when NID_SIGNAL=4 in the CTCS-1 package, determine that the target signal is an approach signal, and judge whether the on-board equipment generates and displays the target distance mode curve for stopping at the approach signal in front and the preset speed of the ceiling; when NID_SIGNAL=7 in the CTCS-1 package, determine that the target signal is an exit signal with an active transponder, and judge whether the on-board equipment generates and displays the target distance mode curve for stopping at the exit signal with an active transponder in front and the preset speed of the ceiling.
[0016] Since different values of NID_SIGNAL in the CTCS-1 package can characterize various specific signal machines involved in the guidance mode, by comparing the specific values of NID_SIGNAL and the speed distance control curve generated by the on-board equipment, the guidance mode of the on-board equipment can be tested simply and more comprehensively, thereby improving the accuracy and efficiency of the on-board equipment guidance mode test.
[0017] In some modified implementations of the first aspect of the present application, after determining whether the on-board equipment generates a fixed mode curve with a ceiling of a preset speed and a preset distance, the method also includes: determining whether the train travels at a speed lower than a preset speed within a preset distance, and determining whether the on-board equipment outputs maximum common braking after the train passes the preset distance.
[0018] After the on-board equipment generates the speed distance control curve, by judging whether the train travels below the preset speed within the preset distance, and whether the on-board equipment outputs braking after the preset distance, it is possible to further detect whether the on-board equipment controls the train travel according to the generated curve, thereby improving the comprehensiveness of the test in the on-board equipment guidance mode.
[0019] In some modified implementations of the first aspect of the present application, before sending the second target code to the on-board device, the method also includes: controlling the train to travel beyond a first defined speed, determining whether the on-board device outputs an alarm, and determining whether the alarm is lifted after the train driver controls the train to decelerate to below the first defined speed for a preset time, and the first defined speed is greater than the preset speed; and / or determining whether the on-board device reminds the driver to confirm after each fixed distance and fixed time the train has traveled, and determining whether the train is traveling normally after the driver presses the confirmation key, and determining whether the on-board device outputs emergency braking and displays guidance to confirm timed braking after the driver does not press the confirmation key, and then determining whether the on-board device redisplays the ceiling as a preset after the driver presses the alert key. A fixed mode curve of a set speed; and / or, controlling the train to travel beyond a second defined speed, determining whether the on-board equipment outputs maximum common braking, and determining whether the on-board equipment outputs relief common braking after the on-board equipment outputs maximum common braking and the train speed is less than a preset speed, and then determining whether the on-board equipment continues to output maximum common braking to stop after the train driver does not press the relief key, and controlling the train to travel beyond a third defined speed after the train driver presses the relief key, determining whether the on-board equipment outputs emergency braking, and determining whether the on-board equipment outputs relief emergency braking after the on-board equipment outputs emergency braking and stops, the second defined speed and the third defined speed are both greater than the preset speed, and the third defined speed is greater than the second defined speed.
[0020] By controlling the train to overspeed and restore to normal speed to check the response of the on-board equipment, and by checking the interaction between the on-board equipment and the driver in the guidance mode, and by controlling the train to overspeed twice in a row to check the braking condition of the on-board equipment, various details in the guidance mode can be applied to the on-board equipment, making the test of the on-board equipment in the guidance mode more refined and achieving more accurate testing in the guidance mode of the on-board equipment.

[0033] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.
[0034] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0035] Currently, there is no accurate testing method for CTCS-2 train control onboard equipment under STCS in guidance mode.
[0036] In view of this, the embodiments of the present application provide a method for testing a vehicle-mounted device in a guide mode, a test device for a vehicle-mounted device in a guide mode, an electronic device, a computer-readable storage medium, and a computer program product. For the vehicle-mounted device, in the guide mode, in addition to using conventional codes to test the vehicle-mounted device, the vehicle-mounted device is also tested using codes corresponding to various situations that may occur in the guide mode. In this way, the test scenarios of the vehicle-mounted device can be enriched, and accurate testing of the vehicle-mounted device in the guide mode can be achieved.
[0037] First, the application scenario of the testing method of the vehicle-mounted device in the guidance mode provided in the embodiment of the present application is described.
[0038] Figure 1This is a schematic diagram of the application scenario architecture of the test method of the vehicle-mounted device in the guidance mode in the embodiment of the present application, see Figure 1 As shown, the architecture may include: a train 11 .
[0039] In the train 11 , onboard equipment 111 is installed.
[0040] The on-board device 111 is used to control the running of the train 11. Before the on-board device 111 is officially put into use in the train 11, it is necessary to first perform a functional test on the on-board device 111. One of the functional tests is to test whether the on-board device 111 can correctly guide the train 11 to run in the guidance mode. The method provided in the embodiment of the present application is to test the guidance mode of the on-board device 111.
[0041] It should be noted here that the various data, devices and processing processes involved in the embodiments of the present application have been authorized in advance by the relevant parties and are legal and compliant.
[0042] Next, the testing method of the vehicle-mounted device in the guidance mode provided in the embodiment of the present application is described in detail.
[0043] Figure 2 The process diagram of the test method of the vehicle-mounted device in the guidance mode in the embodiment of the present application is as follows Figure 1 , see Figure 2 As shown, the method may include:
[0044] S21: Send a first target code to the on-board equipment, which is the train control on-board equipment of CTCS-2 under STCS. The first target code is used to indicate that the guidance signal is open.
[0045] STCS is an improvement on CTCS-2 based on the operation characteristics of urban rail lines, and has the ability to interconnect with CTCS-2. The train control onboard equipment of CTCS-2 under STCS is installed in the train and can control the train running in the urban rail. Before the onboard equipment is officially put into the train to run on the urban rail, the guidance mode of the onboard equipment needs to be tested first.
[0046] When the vehicle-mounted device is in the guidance mode, it generally mainly involves the first target code. The first target code here is used to indicate that the guidance signal is open. In practical applications, the first target code may be an HB code. In view of the fact that railway signal rules may be adjusted over time and the actual situation of railway operations, the first target code only needs to be able to instruct the vehicle-mounted device to enter the guidance mode. The specific content of the first target code is not limited here.
[0047] The first target code may be sent to the on-board device by a signal machine in the automatic block section, or may be manually input into the on-board device. The specific method of sending the first target code to the on-board device may be determined according to actual conditions and is not limited here.
[0048] When the first target code is input into the vehicle-mounted device, the vehicle-mounted device will enter the guidance mode under normal circumstances, and perform corresponding operations in the guidance mode.
[0049] S22: Determine whether the vehicle-mounted device generates and displays a fixed mode curve of the ceiling at a preset speed. If yes, execute S23; if no, execute S26.
[0050] After the vehicle-mounted device enters the guidance mode, under normal circumstances, the vehicle-mounted device will generate and display a fixed mode curve with the roof at a preset speed. If it is detected that the vehicle-mounted device generates and displays a fixed mode curve with the roof at a preset speed, it means that the vehicle-mounted device has entered the guidance mode and is operating normally in the guidance mode. If it is not detected that the vehicle-mounted device generates a fixed mode curve with the roof at a preset speed, or the vehicle-mounted device does not display a fixed mode curve with the roof at a preset speed, it means that the vehicle-mounted device has not successfully entered the guidance mode, or an abnormality has occurred in the guidance mode.
[0051] The preset speed here can generally be 40km / h. As time goes by and the railway operation rules are adjusted, the preset speed may change accordingly. The specific value of the preset speed can be matched with the ceiling limit in the current vehicle equipment guidance mode, and is not limited here.
[0052] S23: Send a second target code to the on-board equipment, where the second target code is used to indicate that an abnormality has occurred in the train operation.
[0053] When it is determined that the vehicle-mounted device generates and displays a fixed mode curve for the ceiling at a preset speed, it means that the response of the vehicle-mounted device based on the conventional code in the guidance mode is normal. At this time, the codes corresponding to other situations involved in the guidance mode can be further input into the vehicle-mounted device to determine whether the response of the vehicle-mounted device to various scenarios in the guidance mode is normal.
[0054] The codes corresponding to other situations involved in the guidance mode are the second target codes here. In practical applications, the second target code can be HU code, NULL code, JC code (27.9Hz) and LOCK code (25.7Hz), etc. The specific content of the second target code is not limited here as long as it can reflect the various situations encountered by the train in the guidance mode.
[0055] Similar to S21, the second target code can also be sent to the on-board equipment by the signal machine in the automatic block section, or can be manually input into the on-board equipment.
[0056] After the on-board device receives the second target code, it will normally respond based on the second target code.
[0057] S24: Determine whether the vehicle-mounted device generates and displays a target distance mode curve for parking at a preset position ahead and a preset speed at the ceiling. If yes, execute S25; if no, execute S26.
[0058] When the guidance mode function of the vehicle-mounted device is normal, after receiving the second target code, the parking position will be further restricted based on the fixed mode curve with the ceiling at the preset speed, that is, a target distance mode curve for parking at the preset position in front and the ceiling at the preset speed is generated and displayed. If it is detected that the vehicle-mounted device generates and displays a target distance mode curve for parking at the preset position in front and the ceiling at the preset speed, it means that the vehicle-mounted device responds normally to other situations in the guidance mode. If it is not detected that the vehicle-mounted device generates a target distance mode curve for parking at the preset position in front and the ceiling at the preset speed, or the vehicle-mounted device does not display a target distance mode curve for parking at the preset position in front and the ceiling at the preset speed, it means that the vehicle-mounted device responds abnormally to other situations in the guidance mode.
[0059] S25: Determine whether the vehicle-mounted device passes the test in the guidance mode.
[0060] When it is determined that the vehicle-mounted device generates and displays the target distance mode curve for parking at the preset position ahead and the ceiling being the preset speed, it indicates that the vehicle-mounted device responds normally to various driving conditions in the guidance mode. At this point, it can be determined that the vehicle-mounted device has passed the test in the guidance mode.
[0061] S26: Determine that the vehicle-mounted device fails the test in the guidance mode.
[0062] When it is determined that the vehicle-mounted device does not generate or display a fixed mode curve with the roof at a preset speed, or when it is determined that the vehicle-mounted device does not generate or display a target distance mode curve for parking at a preset position ahead and the roof at a preset speed, it indicates that the vehicle-mounted device does not respond normally based on a certain driving scenario in the guidance mode. At this point, it can be determined that the vehicle-mounted device has failed the test in the guidance mode.
[0063] From the above content, it can be seen that the testing method of the on-board equipment in the guidance mode provided in the embodiment of the present application, after determining that the on-board equipment generates and displays a fixed mode curve with the ceiling at a preset speed in the guidance mode, continues to input relevant codes for other driving conditions into the on-board equipment, thereby determining whether the on-board equipment can be correctly controlled in various situations encountered in the guidance mode according to the target distance mode curve generated and displayed by the on-board equipment to stop at a preset position in front and the ceiling at a preset speed, thereby achieving accurate testing of the on-board equipment in the guidance mode, reducing the safety risks of the on-board equipment, and improving the safety of train operation.
[0064] Furthermore, as a Figure 2 As a refinement and extension of the method shown, an embodiment of the present application also provides a method for testing a vehicle-mounted device in a guidance mode.
[0065] Figure 3 The process diagram of the test method of the vehicle-mounted device in the guidance mode in the embodiment of the present application is as follows Figure 2 , see Figure 3 As shown, the method may include:
[0066] S31: Sending a first target code to the vehicle-mounted device.
[0067] When it is necessary to perform a functional test on the guidance mode of the on-board equipment, first select the best test line according to the actual situation, then install the on-board equipment to be tested on the train, and then make the train run on the test line.
[0068] The train runs in full mode, with SBI speed less than 45km / h. The onboard equipment is turned on and switched to partial mode. At this point, the test of the onboard equipment in the guide mode begins.
[0069] Send HB code to the vehicle device. If the guidance mode function of the vehicle device is normal, the vehicle device will respond to the HB code and generate and display the fixed mode curve with the roof at 40km / h. If the guidance mode function of the vehicle device is abnormal, the vehicle device will not respond to the HB code, that is, it will not generate or display the fixed mode curve with the roof at 40km / h.
[0070] S32: Determine whether the vehicle-mounted device generates and displays a fixed mode curve of the ceiling at a preset speed. If yes, execute S33; if no, execute S311.
[0071] When making a specific judgment, it can be checked whether the speed distance control curve of the ceiling at the preset speed is displayed in the device management interface (DMI) of the vehicle-mounted device. If yes, it is determined that the vehicle-mounted device generates and displays the fixed mode curve of the ceiling at the preset speed, and then it is determined that the vehicle-mounted device successfully enters the guidance mode, and further testing in the guidance mode can be continued. If not, it is determined that the vehicle-mounted device does not generate or display the fixed mode curve of the ceiling at the preset speed, and then it is determined that the vehicle-mounted device does not successfully enter the guidance mode, and it is directly determined that the guidance mode test of the vehicle-mounted device is abnormal.
[0072] S33: Control the train to travel beyond the first defined speed, determine whether the onboard equipment outputs an alarm, and determine whether the alarm is released after the train driver controls the train to decelerate to below the first defined speed for a preset time, and the first defined speed is greater than the preset speed. If both are yes, execute S34, if at least one is no, execute S311.
[0073] After the on-board equipment enters the guidance mode, continue to test the on-board equipment's response to the train speeding in the guidance mode and its response after the driver takes control.
[0074] Specifically, a speed limit instruction can be input into the on-board device. The speed limit instruction is used to control the train to travel to a specified speed. The specified speed is greater than the first defined speed. And the first defined speed is greater than the preset speed. In other words, the on-board device controls the train to travel beyond the preset speed of the ceiling in the fixed mode curve. For example: the on-board device controls the train to travel at a speed exceeding 42km / h. The first defined speed here can be determined according to actual needs, as long as it is greater than the preset speed, and is not specifically limited here.
[0075] If the onboard equipment outputs an alarm when the train exceeds the first defined speed, it means that the onboard equipment responds normally to the train's overspeeding in the guidance mode, and the next test can be performed. If the onboard equipment does not output an alarm, it means that the onboard equipment responds abnormally to the train's overspeeding in the guidance mode, and the test abnormality and the abnormality are directly reported.
[0076] In practical applications, the alarm output by the vehicle-mounted device may be an audible and visual alarm or a vibration alarm. The specific form of the alarm output by the vehicle-mounted device is not limited here.
[0077] After the on-board device outputs an alarm, the driver will see the alarm and then know that the train is speeding. At this time, the driver will decelerate the train to below the first defined speed. After determining that the train has decelerated to below the first defined speed for a preset time, determine whether the alarm of the on-board device is lifted. If it is determined to be lifted, it means that the on-board device responds normally to overspeed recovery, and the next test can be continued. If it is determined that it has not been lifted, it means that the on-board device responds abnormally to overspeed recovery, and the test abnormality and abnormality are directly reported.
[0078] The preset time here may be 2 seconds. The specific duration of the preset time may be determined according to actual needs and is not limited here.
[0079] S34: Determine whether the onboard equipment reminds the driver to confirm after each fixed distance and fixed time of the train, and determine whether the train is running normally after the driver presses the confirmation key, and determine whether the onboard equipment outputs emergency braking and displays guidance confirmation timeout braking after the driver does not press the confirmation key, and then determine whether the onboard equipment re-displays the fixed mode curve of the ceiling at the preset speed after the driver presses the alert key. If all are yes, execute S35, if at least one is no, execute S311.
[0080] The train runs at a speed limit lower than the preset speed. After each fixed distance and fixed time, the train prompts the driver to confirm through the DMI. If the driver presses the confirmation button and the onboard equipment continues to run normally, it means that the onboard equipment is normal and the next test can be continued. If the driver does not press the confirmation button, the onboard equipment outputs emergency braking and displays the guidance confirmation timeout braking, which means that the onboard equipment is normal and the test can continue. If the onboard equipment does not output emergency braking and displays the guidance confirmation timeout braking, it means that the onboard equipment is abnormal, and the test abnormality and abnormality are directly reported.
[0081] After the driver confirms the overtime braking based on the guidance and does not press the warning button, the on-board equipment will apply emergency braking to the train to stop it after the train has traveled a certain distance or a period of time.
[0082] After seeing the guidance to confirm the overtime braking, the driver pressed the alert button, and the on-board equipment re-displayed the fixed mode curve of the ceiling at the preset speed, indicating that the on-board equipment's function of alert release was normal and the next test could be continued. However, the on-board equipment did not re-display the fixed mode curve of the ceiling at the preset speed, indicating that the on-board equipment's function of alert release was abnormal, and the test abnormality and abnormality were directly reported.
[0083] In actual applications, the fixed distance may be 200m, and the fixed time may be 50s. The specific values of the fixed distance and the fixed time may be determined according to actual conditions and are not limited here. A distance may be 100m, i.e., the train runs to 300m. The certain time may be 10s, i.e., after the train runs for 60s. The specific values of the fixed distance, fixed time, certain distance, and certain time may be determined according to actual conditions and are not limited here.
[0084] S35: Control the train to travel beyond the second defined speed, determine whether the onboard equipment outputs the maximum common braking, and determine whether the onboard equipment outputs the relief common braking after the onboard equipment outputs the maximum common braking and the train speed is less than the preset speed, and then determine whether the onboard equipment continues to output the maximum common braking to stop after the train driver does not press the relief key, and control the train to travel beyond the third defined speed after the train driver presses the relief key, determine whether the onboard equipment outputs the emergency braking, and determine whether the onboard equipment outputs the relief emergency braking after the onboard equipment outputs the emergency braking and stops, the second defined speed and the third defined speed are both greater than the preset speed, and the third defined speed is greater than the second defined speed. If both are yes, execute S36, if at least one is no, execute S311.
[0085] By controlling the train to overspeed twice in succession and checking the response of the on-board equipment, it is possible to test whether there is any abnormality in the braking function of the on-board equipment for multiple overspeeding.
[0086] In practical applications, the second defined speed may be 45 km / h, and the third defined speed may be 50 km / h. The specific values of the second defined speed and the third defined speed may be determined according to actual conditions and are not limited here.
[0087] When the onboard equipment has normal braking function, if the train speed exceeds 45km / h, the onboard equipment will output the maximum common braking, and when the train speed is less than 40km / h, the DMI will be controlled to prompt the driver to release the common braking. If the driver presses the release button, the onboard equipment controls the train to continue running. If the driver does not press the release button, the onboard equipment continues to output the maximum common braking until the train stops.
[0088] After the driver presses the release button, while the train continues to run, if the train speed exceeds 50km / h, the onboard equipment will output emergency braking, and after the train stops, control the DMI to prompt the driver to release the emergency braking. If the driver presses the release button, the onboard equipment controls the train to continue running. If the driver does not press the release button, the onboard equipment continues to output the maximum common braking to control the train to stop.
[0089] In the case of abnormal braking function of the on-board equipment, if the train speed exceeds 45km / h, the on-board equipment will not output the maximum common braking, or when the train speed is less than 40km / h, it will not control the DMI to prompt the driver to release the common braking. If the driver presses the release button, the on-board equipment will not control the train to continue running. If the driver does not press the release button, the on-board equipment will not continue to output the maximum common braking until the train stops.
[0090] After the driver presses the release button, while the train continues to run, if the train speed exceeds 50km / h, the onboard equipment will not output emergency braking, or after the train stops, it will not control the DMI to prompt the driver to release the emergency braking. If the driver presses the release button, the onboard equipment will not control the train to continue running. If the driver does not press the release button, the onboard equipment will not continue to output the maximum common braking to control the train to stop.
[0091] Therefore, through the above series of judgments, it is possible to test whether the on-board equipment reacts normally to the train speeding and whether the driver responds.
[0092] It should be noted that the above steps S33, S34, and S35 can be executed synchronously or asynchronously. The execution order of S33, S34, and S35 is not specifically limited here.
[0093] Next, the codes in various situations can be formally sent to the vehicle-mounted device to determine whether the speed distance control curve generated by the vehicle-mounted device for various codes is correct, thereby determining whether the speed distance control curve generation function of the vehicle-mounted device is normal.
[0094] The various codes here, ie, the second target code, may include multiple types of codes.
[0095] S36: Send each second target code to the vehicle-mounted device in sequence.
[0096] S37: Control the vehicle-mounted equipment to obtain the CTCS-1 packet from the front transponder.
[0097] Similar to each second target code, the different information contained in the CTCS-1 package can also characterize various situations of the vehicle-mounted device in the guidance mode. Therefore, through each second target code and any one or all of the CTCS-1 packages containing different information, it is possible to test whether the vehicle-mounted device responds correctly to various situations in the guidance mode.
[0098] When only each second target code is used, it is necessary to determine whether the vehicle-mounted device sequentially generates and displays a target distance mode curve for parking at a preset position ahead and the ceiling being a preset speed.
[0099] When only the CTCS-1 package containing different information is used, if the CTCS-1 package is obtained, it is necessary to determine the target signal based on the CTCS-1 package and determine whether the on-board equipment generates and displays a target distance mode curve for stopping at the target signal ahead and the ceiling being a preset speed. If the CTCS-1 package is not obtained, it is necessary to determine whether the on-board equipment generates a fixed mode curve for the ceiling being a preset speed and traveling a preset distance.
[0100] The following takes the use of each second target code and a CTCS-1 packet containing different information for testing as an example to illustrate the specific test process.
[0101] S38: If the CTCS-1 package is obtained, the target signal is determined based on the CTCS-1 package, and it is determined whether the vehicle-mounted device generates and displays the target distance mode curve of stopping at the target signal ahead and the ceiling being the preset speed based on each second target code; if the CTCS-1 package is not obtained, it is determined whether the vehicle-mounted device generates the fixed mode curve of the ceiling being the preset speed and the preset distance based on each second target code. If both are yes, execute S39; if at least one is no, execute S311.
[0102] In practical applications, the second target code may include HU code, NULL code, JC code (27.9 Hz) and LOCK code (25.7 Hz).
[0103] HU code, used to indicate timely parking measures.
[0104] NULL code, used to indicate invalidity.
[0105] The JC code (27.9 Hz) is used to represent the abnormal check code generated after the communication establishment fails, that is, the occupancy detection code.
[0106] LOCK code (25.7Hz), used to indicate the locked state.
[0107] NID_SIGNAL in the CTCS-1 packet can include 0, 1, 2, 3, 4, and 7. Different values represent different signal machines.
[0108] The combination of the second target code and the CTCS-1 package may include the following.
[0109] 1-1. The HU code + the front transponder defines a CTCS-1 packet, and NID_SIGNAL in the CTCS-1 packet is 0 (no signal).
[0110] If the HU code and CTCS-1 packet (NID_SIGNAL = 0) are sent to the vehicle-mounted device, the vehicle-mounted device will generate a target distance mode curve for parking at the front insulation joint and the roof at 40km / h under normal circumstances and display the curve on the DMI. If the vehicle-mounted device is abnormal, the target distance mode curve for parking at the front insulation joint and the roof at 40km / h will not be generated and displayed on the DMI.
[0111] Specifically, you can check whether the ceiling speed limit of the curve displayed on the DMI is 40km / h, and whether the distance value (the distance to the front insulation joint) is the same as the distance value in the CTCS-1 package (the current distance to the front insulation joint) to determine whether the curve generated by the on-board equipment is correct. The judgment of whether the subsequent generated curve is correct is similar to this, and will not be repeated hereafter.
[0112] 1-2. The CTCS-1 package is defined in the HU code + the front transponder, and NID_SIGNAL=1 (entry signal) in the CTCS-1 package.
[0113] If the HU code and CTCS-1 packet (NID_SIGNAL = 1) are sent to the on-board equipment, the on-board equipment will generate a target distance pattern curve for stopping at the front station signal and the ceiling is 40km / h under normal circumstances, and display the curve on the DMI.

[0159] If the HU code is sent to the vehicle-mounted device, and the CTCS-1 package is not sent to the vehicle-mounted device or the specific value of NID_SIGNAL is not defined in the CTCS-1 package, the vehicle-mounted device will generate a fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) under normal circumstances, and display the curve on the DMI. If there is an abnormality in the vehicle-mounted device, the fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) will not be generated and displayed on the DMI.
[0160] The distance 1500m here is only a specific example, and can be adjusted to other specific values according to actual conditions, and is not limited here. The subsequent 1500m example is similar to this, and will not be explained separately hereafter.
[0161] 5-2. NULL code + undefined CTCS-1 packet in the front transponder.
[0162] If the NULL code is sent to the vehicle-mounted device, and the CTCS-1 package is not sent to the vehicle-mounted device or the specific value of NID_SIGNAL is not defined in the CTCS-1 package, the vehicle-mounted device will generate a fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) under normal circumstances, and display the curve on the DMI. If there is an abnormality in the vehicle-mounted device, the fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) will not be generated and displayed on the DMI.

[0164] If the JC code (27.9Hz) is sent to the vehicle-mounted device, and the CTCS-1 package is not sent to the vehicle-mounted device or the specific value of NID_SIGNAL is not defined in the CTCS-1 package, the vehicle-mounted device will generate a fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) under normal circumstances, and display the curve on the DMI. If there is an abnormality in the vehicle-mounted device, the fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) will not be generated and displayed on the DMI.
[0165] 5-4. LOCK code (25.7 Hz) + undefined CTCS-1 packet in the front transponder.
[0166] If the LOCK code (25.7Hz) is sent to the vehicle-mounted device, and the CTCS-1 package is not sent to the vehicle-mounted device or the specific value of NID_SIGNAL is not defined in the CTCS-1 package, the vehicle-mounted device will generate a fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) under normal circumstances, and display the curve on the DMI. If there is an abnormality in the vehicle-mounted device, the fixed mode curve with a ceiling of 40km / h and a distance of 1500m (calculated continuously from the beginning of the route) will not be generated and displayed on the DMI.
[0167] After the on-board equipment generates a fixed mode curve with a ceiling of a preset speed and a preset distance, it is necessary to further determine whether the on-board equipment controls the train to travel according to this speed and distance control curve to achieve a more comprehensive test.
[0168] S39: Determine whether the train travels at a speed lower than a preset speed within a preset distance, and determine whether the onboard equipment outputs maximum common braking after the train travels over the preset distance. If both are yes, execute S310, if at least one is no, execute S311.
[0169] After the on-board equipment generates a fixed mode curve with a ceiling of a preset speed and a preset distance, the on-board equipment will control the train to travel at a speed lower than the preset speed within the preset distance, and control the train to stop after traveling the preset distance under normal circumstances. If the on-board equipment is abnormal, the train will not be controlled to travel at a speed lower than the preset speed within the preset distance, or will not be controlled to stop after traveling the preset distance. Therefore, the on-board equipment can be used to determine whether the control of the train's running distance and speed based on the speed distance control curve is normal through the train's running status at different positions.
[0170] Continuing with the above example, after the onboard equipment generates a fixed mode curve with a ceiling of 40km / h and a distance of 1500m, the train is controlled to run at less than 40km / h within 1500m, and after exceeding 1500m, the maximum common braking is output to control the train to stop. At this time, it is possible to monitor whether the train runs at less than 40km / h within 1500m, and whether the train stops after exceeding 1500m, so as to determine whether the onboard equipment's control of the train's operation based on the curve is normal.
[0171] S310: Determine whether the vehicle-mounted device passes the test in the guidance mode.
