All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
FIG. 1 is a schematic flow chart of a testing method of a vehicle-mounted ATP system provided by the present invention. The testing method of the vehicle-mounted ATP system of the invention is described below with reference to FIG. 1. As shown in fig. 1, the method includes: step 101, establishing a track circuit simulation model and a train operation simulation model.
Specifically, the operation of the track circuit and the train can be described mathematically based on the observation and detection of the operation of the track circuit and the train, while ignoring secondary factors and undetectable variables, so that a simplified approximation of a simulation model of the track circuit and a simulation model of the operation of the train can be obtained.
And 102, performing simulated operation on the train according to the predetermined train operation parameters based on the track circuit simulation model and the train operation simulation model.
In particular, train operating parameters may be used to define the operation of the train, such as: the departure point, the destination point, the speed at which the train travels, the acceleration of a certain section, and the like.
Train operation parameters may be predetermined prior to performing the simulated operation of the train. The train operation parameters may be determined with reference to the operation parameters of the train in actual operation.
Based on the established track circuit simulation model and the train operation simulation model, the train can be subjected to simulated operation according to the predetermined train operation parameters, and a scene that the train operates on the track corresponding to the track circuit according to the predetermined train operation parameters is simulated.
And 103, transmitting the information of the target track circuit to a vehicle-mounted ATP system of the train based on the simulated operation data of the train.
Specifically, the simulation operation data of the train may describe the operation state of the train in the simulation operation process, including: real-time speed or real-time position information of the train in the simulation running process and the like.
It should be noted that the real-time position information of the train in the simulation operation process may refer to the real-time position information of the head of the train.
The simulation operation data of the train can be obtained by monitoring the simulation operation train in real time.
Based on the simulated operating data of the train, the occupancy of the track circuit can be determined, for example: it can be determined whether the track corresponding to any track circuit is occupied by a train.
The track circuit associated with the occupancy of the track circuit described above may be taken as the target track circuit, for example: the track circuit corresponding to the track where the train is located at the current moment can be used as a target track circuit; alternatively, the track circuit corresponding to the next track or the previous track of the current train track may be used.
After the target track circuit is determined based on the simulated operation data of the train, information of the target track circuit may be transmitted to the on-board ATP system.
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 may include carrier frequency information of the track circuit and may also include mobile authorization information of the track circuit.
Specifically, the track circuit may have 8 carrier frequencies, for example: 1700Hz, 2000Hz, 2300Hz or 2600Hz, etc. For the purpose of signal handover, the carrier frequencies of any two adjacent track circuits are different. The carrier frequency information of the track circuit may include a carrier frequency of the track circuit.
It should be noted that, during the actual running process of the train, the movement authorization information needs to be periodically sent to the vehicle-mounted ATP system of the train, so that the vehicle-mounted ATP system can control the train according to the received movement authorization information. The tester can also perform abnormal fault setting aiming at different mobile authorization information. In the embodiment of the invention, when the train is subjected to simulation operation, the movement authorization attribute can be given to each track circuit. Therefore, the information of the track circuit may further include movement authorization information of the track circuit.
It should be noted that the movement authorization information of the track circuit may include: the system comprises a code identification, a line ID, an area ID, a track circuit ID, a running direction, a line speed limit, door opening information, a target distance, a shielding door state and the like.
And the coded identification comprises a normal state identification and a special command identification.
The line ID may be used to identify different lines.
The zone IDs may be used to identify different control zones within the same operating line.
The track circuit ID may be used to identify different track circuits within the same control area of the track circuit.
The running direction includes an up direction and a down direction.
The line speed limit can have various speed limit grades.
And door opening information including door forbidding, left door allowing, right door allowing and double-sided door allowing.
The target distance refers to the number of track sections (including the current track) between the current track of the train and the absolute stop signal or the track occupied in front of the train.
It should be noted that, in actual operation, the vehicle-mounted ATP system realizes information interaction with ground devices such as a track circuit through CAN bus communication. In the embodiment of the invention, the information of the target track circuit is sent to the vehicle-mounted ATP system through CAN bus communication.
And 104, acquiring a response result of the vehicle-mounted ATP system responding to the information of the target track circuit, and acquiring a 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.
Specifically, after receiving the information of the target track circuit, the vehicle-mounted ATP system may respond based on the information of the target track circuit, for example: controlling the speed of the train or starting the braking of the train, and the like.
The response result of the on-board ATP system in response to the information of the target track circuit may be acquired in various ways, for example: the response result of the vehicle-mounted ATP system can be obtained by monitoring the control instruction sent by the vehicle-mounted ATP system in real time; alternatively, the response result of the on-board ATP system may be determined by analyzing simulated operation data of the train.
The expected operation corresponding to the information of the track circuit may refer to an operation that should be completed after the on-board ATP system receives the information of the track circuit. The information of the track circuit corresponds to a desired operation which is preset.
After the response result of the vehicle-mounted ATP system in response to the information of the target track circuit is obtained, the response result may be compared with the expected operation corresponding to the information of the target track circuit, and whether the response result is the same as the expected operation corresponding to the information of the target track circuit may be determined.
If the response result is judged to be the same as the expected operation corresponding to the information of the target track circuit, a test result that the vehicle-mounted ATP system is normal in function can be obtained.
If the response result is judged to be different from the expected operation corresponding to the information of the target track circuit, the test result of the abnormal function of the vehicle-mounted ATP system can be obtained.
According to the embodiment of the invention, after the information of the target track circuit is sent to the vehicle-mounted ATP system of the train based on the simulation operation data of the simulation operation of the train, the test result of the vehicle-mounted ATP system is obtained based on the expected operation of the response result of the vehicle-mounted ATP system responding to the information of the target track circuit and the information of the target track circuit, the vehicle-mounted ATP system can be tested under the condition that the real objects such as the train, the track circuit and the like are not called, and the test process is lower in cost and more efficient.
Based on the content of each embodiment, the transmitting the information of the target track circuit to the on-board ATP system of the train based on the simulated operation data of the train specifically includes: and under the condition that the train is determined not to enter the target running section according to the simulated running data of the train, transmitting the movement authorization information of the target track circuit to the vehicle-mounted ATP system at intervals of a first target time period.
And the target track circuit is a track circuit corresponding to the track where the train is located at the current moment.
The target travel interval may be a travel interval obtained by extending a preset distance to two adjacent track circuits on both sides of a boundary between any two adjacent track circuits, with the boundary being a midpoint. The preset distance may be determined according to actual conditions, for example: the predetermined distance may be between 3 and 5 meters, preferably 3.8 meters. The specific value of the preset distance is not limited in the embodiment of the invention.
The fact that the train enters the target driving interval and drives in the target driving interval can indicate that the train is about to enter the next track of the current track from the current track or just enters the current track from the previous track of the current track in the driving direction of the train.
Whether the train enters the target driving interval or not can be determined according to the simulated operation data of the train.
It should be noted that, whether the train enters the target driving interval or not in the embodiment of the present invention may refer to whether the head of the train enters the target driving interval or not.
If the train is determined not to enter the target running section, the track circuit corresponding to the track where the train is located at the current moment can be used as the target track circuit, and the movement authorization information of the track circuit corresponding to the track where the train is located at the current moment can be sent to the vehicle-mounted ATP system every other first target time period.
The vehicle-mounted ATP system can respond according to the received movement authorization information of the track circuit corresponding to the track where the train is located at the current moment.
It should be noted that the first target time period may be determined according to actual situations, for example: the first target time period may be between 300 milliseconds and 800 milliseconds, preferably 500 milliseconds. In the embodiment of the present invention, specific values of the first target time period are not limited.
According to the embodiment of the invention, the movement authorization information of the track circuit corresponding to the track where the train is located at the current moment is sent to the vehicle-mounted ATP system every fixed period under the condition that the train does not enter the target running interval, and the vehicle-mounted ATP system controls the train in response to the movement authorization information of the track circuit corresponding to the track where the train is located at the current moment, so that the vehicle-mounted ATP system is tested according to the response result of the vehicle-mounted ATP system, and the test process is simpler and more efficient.
Based on the content of each embodiment, the transmitting the information of the target track circuit to the on-board ATP system of the train based on the simulated operation data of the train specifically includes: and under the condition that the train is determined to enter the target running section according to the simulated operation data of the train, alternately sending the movement authorization information of the target track circuit corresponding to the target running section.
Specifically, two adjacent track circuits related to the target travel section may be set as the target track circuit corresponding to the target travel section. After the train enters the target running interval, the target track circuit corresponding to the target running interval is the track circuit corresponding to the track where the train is located at the current moment, and the track circuit corresponding to the next track or the previous track of the track where the train is located at the current moment in the running direction of the train.
Whether the train enters the target driving interval or not can be determined according to the simulated operation data of the train.
After the train is determined to enter the target running section, the movement authorization information of the target track circuit corresponding to the target running section can be alternately sent to the vehicle-mounted ATP system every first target time period.
It should be noted that the CAN bus communication for information interaction with the vehicle-mounted ATP system only includes one CAN bus channel, and therefore, it is necessary to alternately transmit the movement authorization information of the target track circuit corresponding to the target travel section.
It should be noted that the movement authorization information of the target track circuit corresponding to the target travel section may be alternately transmitted in various manners: for example: for the continuous 6 first target time periods, 3 continuous first target time periods can be used as a group, the movement 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 movement authorization information of the track circuit corresponding to the next track or the previous track where the train is currently located in the train running direction is sent in the last 3 first target time periods; before the train passes through the middle point of the target running interval, the 1 st target time period sends the movement authorization information of the track circuit corresponding to the track where the train is currently located, the 2 nd target time period sends the movement authorization information of the track circuit corresponding to the track next to the track where the train is currently located in the running direction of the train, the 3 rd target time period sends the movement authorization information of the track circuit corresponding to the track where the train is currently located, the 4 th target time period sends the movement authorization information of the track circuit corresponding to the track next to the track where the train is currently located in the running direction of the train, and the like; after the train passes through the middle point of the target running section, the 1 st target time period sends the movement authorization information of the track circuit corresponding to the track where the train is currently located, the 2 nd target time period sends the movement authorization information of the track circuit corresponding to the previous track of the track where the train is currently located in the running direction of the train, the 3 rd target time period sends the movement authorization information of the track circuit corresponding to the track where the train is currently located, the 4 th target time period sends the movement authorization information of the track circuit corresponding to the previous track of the track where the train is currently located in the running direction of the train, and the like.
The vehicle-mounted ATP system can respond according to the received movement authorization information of the target track circuit corresponding to the target running section.
According to the embodiment of the invention, under the condition that the train enters the target running interval, the movement authorization information of two adjacent track circuits related to the target running interval is alternately sent to the vehicle-mounted ATP system at regular intervals, and the vehicle-mounted ATP system controls the train in response to the movement authorization information of the two adjacent track circuits related to the target running interval, so that the vehicle-mounted ATP system is tested according to the response result of the vehicle-mounted ATP system, the vehicle-mounted ATP system can acquire more movement authorization information under the condition that the train enters the target running interval, and can control the train based on more movement authorization information, so that the more accurate response result of the vehicle-mounted ATP system is acquired, and the test result of the vehicle-mounted ATP system can be acquired more accurately.

It should be noted that whether the train passes through the insulation joint may refer to whether the foremost end of the train head passes through the insulation joint.
If the train is determined to pass through the insulation section, the track circuit corresponding to the track where the train is located at the current moment can be used as the target track circuit, and the carrier frequency information of the target track circuit can be sent to the vehicle-mounted ATP system.
After receiving the carrier frequency information of the target track circuit, the vehicle-mounted ATP system may determine the position of the train based on the carrier frequency information, and use the position of the train determined by the vehicle-mounted ATP system based on the carrier frequency information as a response result of the vehicle-mounted ATP.
Specifically, the position of the train determined by the vehicle-mounted ATP system based on the carrier frequency information may be compared with the train simulation operation data, and it may be determined whether the position of the train determined by the vehicle-mounted ATP system based on the carrier frequency information is the same as the actual position of the train in the train simulation operation data.
