[0045] In order to make the objects, technical solutions and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the present application with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based upon the embodiments in the present application, all other embodiments obtained by those ordinarily skilled in the art without creative effort should fall into the scope of the present application.
[0046] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mounting", "connection", "linking" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal connection of two elements. For those ordinarily skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.
[0047] Figure 1 is a flowchart of the test method of the vehicle-mounted ATP system provided by the present application. The following will describe the test method of the vehicle-mounted ATP system provided by the present application with reference to Figure 1 The test method of the vehicle-mounted ATP system provided by the present application will be described as shown in the following. Figure 1 The method comprises the following steps.
[0048] Specifically, based upon the observation and detection of the track circuit and the train operation, and by neglecting the secondary factors and undetectable variables, the track circuit and the train operation can be described by mathematical method, so that the simulation model of the track circuit and the simulation model of the train operation can be obtained.
[0049] The method comprises the following steps.
[0050] Specifically, the train operation parameters can be used to define the train operation, for example, the departure place, the destination place, the driving speed and the acceleration of a certain section of the train.
[0051] Before the simulation operation of the train, the train operation parameters can be determined in advance. The train operation parameters can be determined by referring to the operation parameters during the actual operation of the train.
[0052] Based upon the established simulation model of the track circuit and the simulation model of the train operation, according to the predetermined train operation parameters, the simulation operation of the train can be performed, so as to simulate the scenario that the train operates on the track corresponding to the track circuit according to the predetermined train operation parameters.
[0053] Step 103, sending information of the target track circuit to the on-board ATP system of the train based on the simulation running data of the train.
[0054] Specifically, the simulation running data of the train can describe the running state of the train in the simulation running process, including real-time speed or real-time position information of the train in the simulation running process, etc.
[0055] It should be noted that the real-time position information of the train in the simulation running process can refer to the real-time position information of the front end of the train head.
[0056] The simulation running data of the train can be obtained by real-time monitoring of the simulation running train.
[0057] Based on the simulation running data of the train, the occupation of the track circuit can be determined, for example, whether the track corresponding to any track circuit is occupied by the train.
[0058] The track circuit related to the occupation of the track circuit described above can be taken as the target track circuit, for example, the track circuit corresponding to the track where the train is located at the current time can be taken as the target track circuit, or the track circuit corresponding to the next track or the previous track of the track where the train is located at the current time in the running direction of the train, etc.
[0059] After determining the target track circuit based on the simulation running data of the train, the information of the target track circuit can be sent to the on-board ATP system.
[0060] It should be noted that the information of the track circuit can be used to describe the track circuit, for example, the information of the track circuit can include the carrier frequency information of the track circuit, and can also include the movement authority information of the track circuit.
[0061] Specifically, the track circuit can have 8 carrier frequencies, for example, 1700Hz, 2000Hz, 2300Hz or 2600Hz, etc. In order to realize inter-district transmission of signals, the carrier frequencies of any two adjacent track circuits are different. The carrier frequency information of the track circuit can include the carrier frequency of the track circuit.
[0062] It should be noted that in the actual running process of the train, the movement authority information needs to be periodically sent to the on-board ATP system of the train, so that the on-board ATP system can control the train according to the received movement authority information. The tester can also set abnormal faults for different movement authority information. In the simulation running of the train in the embodiment of the present application, the movement authority attribute can be given to each track circuit. Therefore, the information of the track circuit can also include the movement authority information of the track circuit.
[0063] It should be noted that the moving authorization information of the track circuit can include: code identification, line ID, area ID, track circuit ID, running direction, line speed limit, door opening information, target distance, and shield door state.
[0064] The code identification includes normal state and special command identification.
[0065] The line ID can be used to identify different lines.
[0066] The area ID can be used to identify different control areas in the same running line.
[0067] The track circuit ID can be used to identify different track circuits in the same control area of the track circuit.
[0068] The running direction includes the uplink direction and the downlink direction.
[0069] The line speed limit can have multiple speed limit levels.
[0070] The door opening information includes door opening prohibition, left door permission, right door permission, and simultaneous permission of both sides of the door.
[0071] The target distance refers to the number of track sections between the current track of the train and the absolute stop signal or the front occupied track (including the current track).
[0072] It should be noted that the vehicle-mounted ATP system realizes information interaction with ground equipment such as track circuits through CAN bus communication in actual operation. In the embodiment of the present application, the information of the target track circuit is sent to the vehicle-mounted ATP system through CAN bus communication.
[0073] Step 104, obtaining the response result of the vehicle-mounted ATP system in response to the information of the target track circuit, and obtaining the test result of the vehicle-mounted ATP system based on the expected operation corresponding to the response result and the information of the target track circuit.
[0074] Specifically, after the vehicle-mounted ATP system receives the information of the target track circuit, it can respond based on the information of the target track circuit, for example: controlling the train speed or starting the train brake.
[0075] The response result of the vehicle-mounted ATP system in response to the information of the target track circuit can be obtained in various ways, for example: the response result of the vehicle-mounted ATP system can be obtained by monitoring the control instructions issued by the vehicle-mounted ATP system in real time; or the response result of the vehicle-mounted ATP system can be determined by analyzing the simulation running data of the train.
[0076] The expected operation corresponding to the information of the track circuit can refer to an operation that should be completed by the on-board ATP system after receiving the information of the track circuit. The expected operation corresponding to the information of the track circuit is preset.
[0077] After obtaining the response result of the on-board ATP system in response to the information of the target track circuit, the response result can be compared with the expected operation corresponding to the information of the target track circuit, to determine whether the response result is the same as the expected operation corresponding to the information of the target track circuit.
[0078] If it is determined that the response result is the same as the expected operation corresponding to the information of the target track circuit, a test result that the on-board ATP system functions normally can be obtained.
[0079] If it is determined that the response result is different from the expected operation corresponding to the information of the target track circuit, a test result that the on-board ATP system functions abnormally can be obtained.
[0080] The embodiment of the present application can obtain a test result of the on-board ATP system based on a response result of the on-board ATP system in response to the information of the target track circuit and an expected operation corresponding to the information of the target track circuit after sending the information of the target track circuit to the on-board ATP system of the train based on simulation running data of the train in simulation running, so that the on-board ATP system can be tested without calling real trains and track circuits, and the testing process is lower in cost and more efficient.
[0081] Based on the content of the above embodiments, the information of the target track circuit is sent to the on-board ATP system of the train based on simulation running data of the train, and specifically includes: in a case where it is determined according to the simulation running data of the train that the train does not enter a target running section, sending the movement authority information of the target track circuit to the on-board ATP system every first target time period.
[0082] The target track circuit is a track circuit corresponding to a track where the train is currently located.
[0083] The target running section can refer to a running section obtained by extending a preset distance to two adjacent track circuits on both sides of a midpoint at a junction of the two adjacent track circuits. The preset distance can be determined according to actual conditions, for example, the preset distance can be between 3 meters and 5 meters, and is preferably 3.8 meters. The specific value of the preset distance is not limited in the embodiment of the present application.
[0084] The train entering the target running section and running in the target running section can mean that the train is about to enter a next track from a current track, or has just entered the current track from a previous track in the direction of train running.
[0085] According to the simulation running data of the train, it can be determined whether the train enters the target running section.
[0086] It should be noted that, in the embodiment of the present application, whether the train enters the target running section can refer to whether the front end of the train head enters the target running section.
[0087] If it is determined that the train does not enter the target running section, the track circuit corresponding to the track where the train is currently located can be taken as the target track circuit, and the movement authority information of the track circuit corresponding to the track where the train is currently located can be sent to the on-board ATP system at a first target time interval.
[0088] The on-board ATP system can respond according to the received movement authority information of the track circuit corresponding to the track where the train is currently located.
[0089] It should be noted that the first target time interval can be determined according to actual conditions, for example, the first target time interval can be between 300 milliseconds and 800 milliseconds, and preferably 500 milliseconds. In the embodiment of the present application, the specific value of the first target time interval is not limited.
[0090] In the embodiment of the present application, the movement authority information of the track circuit corresponding to the track where the train is currently located is sent to the on-board ATP system at a fixed interval when the train does not enter the target running section, and the on-board ATP system responds to the movement authority information of the track circuit corresponding to the track where the train is currently located to control the train, so that the on-board ATP system is tested according to the response result of the on-board ATP system, and the testing process is simpler and more efficient.
[0091] Based on the above embodiments, the information of the target track circuit is sent to the on-board ATP system of the train based on the simulation running data of the train, specifically including: in the case where it is determined that the train enters the target running section according to the simulation running data of the train, the movement authority information of the target track circuit corresponding to the target running section is alternately sent.
[0092] Specifically, the two adjacent track circuits involved in the target running section can be taken as the target track circuit corresponding to the target running section. After the train enters the target running section, the target track circuit corresponding to the target running section is the track circuit corresponding to the track where the train is currently located, and the track circuit corresponding to the next track or the previous track of the track where the train is currently located in the direction of train running.
[0093] According to the simulation running data of the train, it can be determined whether the train enters the target running section.
[0094] After determining that the train enters the target running section, the mobile authorization information of the target track circuit corresponding to the target running section can be alternately sent to the on-board ATP system every first target time period.
[0095] It should be noted that the CAN bus communication for information interaction with the on-board ATP system only includes one CAN bus channel, and therefore the mobile authorization information of the target track circuit corresponding to the target running section needs to be alternately sent.
[0096] It should be noted that the mobile authorization information of the target track circuit corresponding to the target running section can be alternately sent in various ways: for example, for the continuous 6 first target time periods, the continuous 3 first target time periods can be taken as a group, the mobile authorization information of the track circuit corresponding to the track where the train is currently located is sent in the first 3 first target time periods, and the mobile authorization information of the track circuit corresponding to the next track or the previous track of the track where the train is currently located in the train running direction is sent in the last 3 first target time periods; the mobile authorization information of the track circuit corresponding to the track where the train is currently located can also be sent in the first target time period before the train passes the midpoint of the target running section, the mobile authorization information of the track circuit corresponding to the next track of the track where the train is currently located in the train running direction is sent in the second target time period, the mobile authorization information of the track circuit corresponding to the track where the train is currently located is sent in the third target time period, the mobile authorization information of the track circuit corresponding to the next track of the track where the train is currently located in the train running direction is sent in the fourth target time period, and so on; after the train passes the midpoint of the target running section, the mobile authorization information of the track circuit corresponding to the track where the train is currently located is sent in the first target time period, the mobile authorization information of the track circuit corresponding to the previous track of the track where the train is currently located in the train running direction is sent in the second target time period, the mobile authorization information of the track circuit corresponding to the track where the train is currently located is sent in the third target time period, the mobile authorization information of the track circuit corresponding to the previous track of the track where the train is currently located in the train running direction is sent in the fourth target time period, and so on.
[0097] The on-board ATP system can respond according to the received mobile authorization information of the target track circuit corresponding to the target running section.
[0098] The embodiment of the present application can test the on-board ATP system according to the response result of the on-board ATP system, the on-board ATP system can obtain more movement authorization information when the train enters the target running section, and can control the train based on more movement authorization information, obtain more accurate response results of the on-board ATP system, and then can more accurately obtain the test results of the on-board ATP system.
[0099] Based on the content of each of the above embodiments, the information of the target track circuit is sent to the on-board ATP system of the train based on the simulation running data of the train, specifically including: sending the carrier frequency information of the target track circuit to the on-board ATP system when it is determined that the train passes any insulating joint according to the simulation running data of the train.
[0100] The insulating joint is located between the target track circuit and the last track circuit of the target track circuit in the train running direction.
[0101] Specifically, an insulating joint is arranged between any two adjacent track circuits. In the embodiment of the present application, the track circuit corresponding to the track where the train is currently located is taken as the target track circuit, and the insulating joint is located between the target track circuit and the last track circuit of the target track circuit in the train running direction.
[0102] The train passing any insulating joint can mean that the train has entered the next track of the current track from the current track.
[0103] For any insulating joint, it can be determined according to the simulation running data of the train whether the train passes the insulating joint.
[0104] It should be noted that whether the train passes the insulating joint can mean whether the front end of the train head passes the insulating joint.
[0105] If it is determined that the train passes the insulating joint, the track circuit corresponding to the track where the train is currently located can be taken as the target track circuit, and the carrier frequency information of the target track circuit is sent to the on-board ATP system.
[0106] After the on-board ATP system receives the carrier frequency information of the target track circuit, the position of the train can be determined based on the above carrier frequency information, and the position of the train determined by the on-board ATP system based on the above carrier frequency information is taken as the response result of the on-board ATP.
[0107] Specifically, the position of the train determined by the on-board ATP system based on the carrier frequency information can be compared with the train simulation running data to determine whether the position of the train determined by the on-board ATP system based on the carrier frequency information is the same as the actual position of the train in the train simulation running data.
[0108] If it is determined that the position of the train determined by the on-board ATP system based on the carrier frequency information is the same as the actual position of the train in the train simulation running data, a test result that the positioning function of the on-board ATP system is normal can be obtained.
[0109] If it is determined that the position of the train determined by the on-board ATP system based on the carrier frequency information is different from the actual position of the train in the train simulation running data, a test result that the positioning function of the on-board ATP system is abnormal can be obtained.
[0110] According to the embodiment of the present application, after the train passes through any insulating joint, the carrier frequency information of the track circuit corresponding to the track where the train is currently located is sent to the on-board ATP system, and the on-board ATP system responds to the carrier frequency information of the track circuit corresponding to the track where the train is currently located to position the train, so that the positioning function of the on-board ATP system can be tested, and the testing process is simpler and more efficient.
[0111] Based on the content of the above embodiments, the response result of the on-board ATP system in response to the information of the target track circuit is obtained, and based on the response result and the expected operation corresponding to the information of the target track circuit, the test result of the on-board ATP system is obtained, specifically including: in the case where the simulation running data of the train is accurate, the response result of the on-board ATP system in response to the information of the target track circuit is obtained.
[0112] Specifically, when the on-board ATP system is tested based on the simulation running data of the train, in the case where the simulation running data of the train is accurate, it can be ensured that the test result of the on-board ATP system obtained is accurate.
[0113] Before obtaining the response result of the on-board ATP system according to the information of the target track circuit, it can be determined whether the simulation running data of the train is accurate. In the case where the simulation running data of the train is accurate, the response result of the on-board ATP system according to the information of the target track circuit is obtained, and based on the response result and the expected operation corresponding to the target track circuit, the test result of the on-board ATP system is obtained.
[0114] The accuracy of the simulation running data of the train can be verified in various ways, for example: the simulation running data of the train can be compared with preset simulation running parameters to determine whether the simulation running data of the train is accurate.
[0115] Based on the response result and the expected operation corresponding to the information of the target track circuit, a test result of the on-board ATP system is obtained.
[0116] Specifically, after obtaining the response result of the on-board ATP system in response to the information of the target track circuit, based on the response result and the expected operation corresponding to the information of the target track circuit, the test result of the on-board ATP system is obtained.
[0117] The embodiment of the present application can more accurately obtain the test result of the on-board ATP system by determining that the simulation running data of the train is accurate, and based on the response result of the on-board ATP system in response to the information of the target track circuit and the expected operation corresponding to the information of the target track circuit.
[0118] Based on the content of the above embodiments, the simulation running data of the train is determined to be accurate, and specifically includes: receiving a query instruction sent by the on-board ATP system every second target time period.
[0119] Specifically, the on-board ATP can send the query instruction through CAN bus communication every second target time period.
[0120] In response to the query instruction, it is determined whether the simulation running of the train is in a normal state.
[0121] For any query instruction, after receiving the query instruction, it is determined whether the simulation running of the train is in a normal state in response to the query instruction.
[0122] It should be noted that the second target time period can be determined according to actual conditions, for example, the first target time period can be between 500 milliseconds and 1 second. The specific value of the first target time period in the embodiment of the present application is not limited.
[0123] In the case that the simulation running of the train is in a normal state, information indicating that the simulation running data of the train is accurate is returned to the on-board ATP system, so that the on-board ATP system responds to the received information of the target track circuit.
[0124] Specifically, after determining that the simulation running of the train is in a normal state, information indicating that the simulation running data of the train is accurate can be immediately returned to the on-board ATP system. After the on-board ATP system receives the above information indicating that the simulation running data of the train is accurate, it can respond based on the received information of the target track circuit.
[0125] It should be noted that after the on-board ATP system receives the above information indicating that the simulation running data of the train is accurate, a count value indicating that the simulation running data of the train is accurate can also be increased by 1.
[0126] It should be noted that the information indicating whether the simulation running data of the train is accurate can also be actively sent to the vehicle-mounted ATP system.
[0127] The response result of the vehicle-mounted ATP system responding to the information of the target track circuit is acquired.
[0128] Specifically, after the vehicle-mounted ATP system responds based on the received information of the target track circuit, the response result of the vehicle-mounted ATP system according to the information of the target track circuit can be acquired.
[0129] After the simulation running of the train is determined to be in a normal state by responding to the query instruction sent by the vehicle-mounted ATP system every second target time period, the information indicating that the simulation running data of the train is accurate is returned to the vehicle-mounted ATP system, so that the vehicle-mounted ATP system can respond based on the received information of the target track circuit, and further acquire the test result of the vehicle-mounted ATP system based on the response result of the vehicle-mounted ATP system according to the information of the target track circuit, and ensure that the simulation running data of the train is accurate during the test of the vehicle-mounted ATP system, and more accurately obtain the test result of the vehicle-mounted ATP system.
[0130] Based on the content of each of the above embodiments, after the information of the target track circuit is sent to the vehicle-mounted ATP system of the train based on the simulation running data of the train, the identification of the target track circuit is recorded.
[0131] Specifically, after the information of the target track circuit is sent to the vehicle-mounted ATP system of the train, the identification of the target track circuit can be recorded, so that the driving path of the train can be acquired based on the recorded identification of each target track circuit.
[0132] The embodiment of the present application can provide a data basis for subsequent test analysis by recording the identification of the target track circuit.
[0133] In order to facilitate the understanding of the vehicle-mounted ATP system test method of the present application, the following describes the sending of the information of the target track circuit to the vehicle-mounted ATP system of the train based on the simulation running data of the train in each embodiment of the present application through an example.
[0134] Figure 2 is one of the simulation running schematic diagrams of the train in the vehicle-mounted ATP system test method provided by the present application. As shown in Figure 2 The simulation path includes three track circuits, and the three track circuits correspond to track circuit 203, track circuit 204 and track circuit 205 arranged in sequence, respectively. An insulating joint 202 is arranged between any two track circuits. The departure location of the train is the first insulating joint 202. When the train 201 is located at the departure location, the carrier frequency information a of the track circuit 203 can be sent to the vehicle-mounted ATP system, and the sending is only once.
[0135] Figure 3 Figure 2 is a schematic diagram of a second train simulation running in a method for testing a vehicle-mounted ATP system according to the present application. As shown in the figure, the train enters a target running section 301. The target running section 301 corresponds to a target track circuit, which can be track circuit 203 and track circuit 204. Figure 3
[0136] During the running of the train in the target running section 301, the track circuit 203 and the track circuit 204 can alternately send the movement authority information to the vehicle-mounted ATP system.
[0137] It should be noted that during the running of the train, the movement authority information of the track circuit corresponding to the track where the train is currently located can be sent to the vehicle-mounted ATP system every first target time period, when it is determined that the train has not entered the target running section 301.
[0138] Figure 4 Figure 3 is a schematic diagram of a third train simulation running in a method for testing a vehicle-mounted ATP system according to the present application. As shown in the figure, the train passes through the insulating joint 202, and the track circuit corresponding to the track where the train is currently located is the track circuit 204. Figure 4
[0139] The carrier frequency information b of the track circuit 204 corresponding to the track where the train is currently located can be sent to the vehicle-mounted ATP system immediately after the train passes through the insulating joint 202, and only once.
[0140] Figure 5 Figure 4 is a schematic diagram of a fourth train simulation running in a method for testing a vehicle-mounted ATP system according to the present application. As shown in the figure, the destination of the train is at the last insulating joint 202. Figure 5
