[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0014] An embodiment of the present application provides a rail transit test system, which includes an automatic control module and a forwarding server. The automatic control module can obtain target test train information from the forwarding server and communicate with the target test train, so as to control the target test train to run according to the acquired running speed and position information to realize the test of the target test train.

[0015] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0016] Please refer to Figure 1 , Figure 1 A schematic diagram of a rail transit test system provided in an embodiment of the present application.

[0017] like Figure 1 As shown, the rail transit test system includes an automatic control module and a forwarding server, and the forwarding server is communicatively connected with the automatic control module so that the automatic control module can obtain information from the forwarding server.

[0018] Exemplarily, the forwarding server stores multiple train information so that the automatic control module obtains the train information and tests the train corresponding to the train information. Specifically, the automatic control module obtains the target test train information in the forwarding server and establishes a communication connection with the target test train according to the target test train information.

[0019] For example, the automatic control module obtains the driving plan and operation diagram information from the forwarding server, and determines the target test train information corresponding to the target test train to be tested based on the driving plan and operation diagram information, thereby establishing a communication connection with the target test train based on the target test train information.

[0020] In some embodiments, the automatic control module is further used to determine whether to establish a communication connection with the target test train based on the target test train information and the interface information between the automatic control module and the onboard equipment of the target test train.

[0021] Exemplarily, during the process of establishing communication between the automatic control module and the target test train, if the automatic control module determines that the communication connection is completed, optionally, based on the target test train information and the interface information between the automatic control module and the on-board equipment of the target test train, it is verified whether the automatic control module has successfully established a communication connection with the target test train.

[0022] It can be understood that the target test train information includes information corresponding to the on-board equipment on the target test train. Therefore, it is possible to determine whether to establish a communication connection with the on-board equipment of the target test train based on the information corresponding to the on-board equipment included in the target test train information and the interface information obtained by the automatic control module after establishing the connection.

[0023] The automatic control module is also used to determine the running speed of the target test train according to the acquired station configuration data, and to obtain the location information of the target test train, and to determine the target section occupancy instruction to be sent to the forwarding server according to the location information, so that the forwarding server can determine whether the target section is in an occupied state; thereby, when the target section is in a cleared state, the target test train can run in the target section for testing.

[0024] For example, the configuration data of the station yard includes platform information, the distance between stations, and the preset stop time, so as to determine the running speed of the target test train according to the distance between stations and the preset stop time. 1 =60m1, then the target test train running speed between the stations is v 1 =S / T s , where T s Used to indicate the time required to pass between stations.

[0025] It is understandable that the target test train arrives at each station at a corresponding time point, and in the actual operation scenario of the train, the stop time at each station will be different. Therefore, the stop time at each station and the running speed between stations can be adjusted to simulate the current situation of changes in stop time due to changes in passenger flow during peak and valley stages, so as to achieve a more realistic test result.

[0026] In some embodiments, determining the running speed according to the acquired station configuration data includes: determining the corresponding running speed of the target test train between target stations according to the acquired stop duration and the distance between target stations.

[0027] Specifically, the stop time is used to indicate the actual stop time, with the preset stop time as t 1 =60m1, the actual stop time is t 2 =60(m1+m2) as an example, if the distance between the target stations is S=v 1 T S , then the corresponding running speed between target stations is v 2 =S / (T S -60m2) so that the running speed of the target test train between target stations can be adjusted according to the actual stop time.

[0028] In the specific implementation process, it is determined whether the target interval running speed calculated above meets the conditions according to the preset speed threshold to avoid overspeeding of the train between stations.

[0029] For example, when the calculated running speed between the target stations is less than or equal to the preset speed threshold, it is determined whether the running speed meets the conditions, and the target test train is controlled to run at the running speed; if the calculated running speed between the target stations is greater than the preset speed threshold, it is determined that the running speed is overspeeding, and the target test train is controlled to run at the preset speed threshold.

[0030] The automatic control module can also determine the target section occupancy instruction to be sent to the forwarding server based on the location information of the target test train. It can be understood that the target section occupancy instruction is used to indicate the need to enter the target section, thereby determining whether the target section is occupied by other trains and avoiding other trains from entering.

[0031] In some embodiments, the target section occupancy instruction to be sent to the forwarding server is determined based on the position information, including: if the position of the target test train determined based on the position information and the starting position of the target section are less than or equal to a first preset distance threshold, the target section occupancy instruction to be sent to the forwarding server is determined.

[0032] Exemplarily, if the position of the target test train and the starting position of the target section are less than or equal to a first preset threshold, it is determined that the target test train is about to enter the target section, and thus the target section station instruction is determined and sent to the forwarding server.

[0033] In the specific implementation process, the automatic control module obtains the kilometer mark information of the target test train through the on-board equipment of the target test train to determine the position of the target test train according to the kilometer mark information. For example, the target test train needs to pass through multiple sections, and the lengths of at least two sections are different. For example, the length of the first section is 1000km, the length of the second section is 1500km, and the second section is the target section; when the kilometer mark information calculation starting point of the target test train coincides with the starting position of the first section, and the first preset threshold is 5m, if the kilometer mark information obtained is 999.005km, it is determined that the starting position of the target test train and the second section is less than or equal to the first preset threshold, and it is determined that the target test train is about to enter the second section, and the occupancy information of the second section is sent to the forwarding server to determine the position of the target test train through the kilometer mark information and the section length, and determine whether the target test train enters the target section. At the same time, the automatic control module sends corresponding instructions to the forwarding server to write data to realize the automatic occupation operation of the target section.

[0034] In some embodiments, after receiving the target section occupancy instruction, the forwarding server determines whether the target section is in a clearing state. If the target section is in a clearing state, it sends an entry instruction to the automatic control module so that the automatic control module controls the target test train to enter the target section, thereby enabling the target test train to run at the operating speed in the target section.

[0035] It can be understood that after receiving the target section occupation instruction, the forwarding server determines whether the target section is occupied. If the target section is not occupied, that is, the target section is in a cleared state, an entry instruction allowing entry is sent to the automatic control module, so that the automatic control module controls the target test train to enter the target section and realize the running car.

[0036] At the same time, the forwarding server also changes the target section to an occupied state to prevent other trains from entering.

[0037] In some embodiments, the forwarding server is further configured to send a stop entry instruction to the automatic control module when determining that the target section is in an occupied state, so that the automatic control module controls the target test train to stop entering the target section.

[0038] It can be understood that after the forwarding server receives the target section occupancy instruction, if it is determined that the target section is in an occupied state, a stop entry instruction is sent to the automatic control module so that the automatic control module controls the target test train to stop entering the target section, thereby realizing automatic occupancy of the section, avoiding manual adjustment, and improving the accuracy and efficiency of the test.

[0039] In some embodiments, the automatic control module is also used to determine the target section clearing instruction and send it to the forwarding server when the distance between the position of the target test train and the end position of the target section is greater than a second preset distance threshold, so that the forwarding server changes the status of the target section to a clearing status, wherein the second preset distance threshold is greater than the first preset distance threshold.

[0040] Optionally, the position of the target test train is determined based on the kilometer landmark information of the target test train.

[0041] In the specific implementation process, take the example that the length of the first section is 1000km, the length of the second section is 1500km, the second section is the target section, and the second preset distance threshold is 45m; it can be understood that the end position of the second section can be determined to be 2500km through the above values. If the kilometer mark information obtained is 2500.046km, the distance between the position of the target test train and the end position of the target section is determined to be 46m, which is greater than the second preset distance threshold. The target test train is determined to leave the target section, and a target section clearing instruction is sent to the forwarding server, so that the forwarding server changes the state of the target section to the clearing state when receiving the target section clearing instruction, thereby completing the automated section occupancy and clearing operations.

[0042] It can be understood that when the target section is in a cleared state, the automatic control module can control the target test train to enter the target section and run at a running speed in the target section, thereby realizing a running car test of the target test train.

[0043] See also Figure 2 , Figure 2 A practical scenario diagram of a rail transit test system provided in one embodiment of the present application.

[0044] In some embodiments, the rail transit test system also includes a train monitoring module, which is communicatively connected to the automatic control module; the automatic control module is also used to determine the completion status of the preset operation plan based on the preset operation plan corresponding to the target test train obtained by the train monitoring module, and the running state of the target test train; if it is determined that the target test train has completed the preset operation plan, the target test train is controlled to perform a terminal change operation.

[0045] Exemplarily, the train monitoring module stores a preset operation plan and bound vehicle information. The automatic control module can obtain the above information stored in the train monitoring module and establish communication with the target test train according to the test requirements, determine the operating speed of the target train and determine the target section to control the target test train. After determining that the target test train has completed the preset operation plan, the target test train is controlled to perform an end-changing operation to realize the automatic CN150-22010PI end-changing operation of the train, so as to control the target test train to execute the next trip plan, thereby completing the automatic switching process of the train between different service numbers with the same number, thereby improving the efficiency of the test.

[0046] Optionally, the train monitoring module sends the preset operation plan corresponding to the train to the forwarding server so that the forwarding server stores the preset operation plan, so that the automatic control module can obtain the preset operation plan of the train from the forwarding server.

[0047] During the specific implementation process, the automatic control module determines whether the target test train has completed the kilometer mileage in the preset operation plan based on the acquired kilometer mark information. If it is determined that the target train has completed the kilometer mileage in the preset operation plan and that the operating speed of the target test train is zero, the target test train is controlled to perform the end change operation.

[0048] In some embodiments, the automatic control module is further used to control the target test train to stop at the target station according to the parking time corresponding to the target station, and control the target test train to start after the parking time has passed.

[0049] At present, most simulation and actual use environments use the automatic train operation system (Automatic Train Operation) to remind the driver to perform departure operations through departure indicator lights and TOD. The driver needs to manually press a button to complete the departure operation, and manually control the train's running speed to complete the vehicle's start and stop process. Therefore, when the train needs to perform long-term running tests as planned, this test method will greatly reduce the efficiency of the running test. Therefore, a large amount of manpower will be required during the test process, and factors such as unexpected operational risks and human intervention will be introduced. The automatic control module of the rail transit test system of the present application can automatically calculate the parking time, and after the preset parking time, start the target test train based on the preset acceleration and run at the target running speed when the target test train reaches the target running speed to complete the train automatic parking and start operations, saving labor costs, reducing operational risk factors, and improving test efficiency.

[0050] In some embodiments, the automatic control module is further used to traverse the beacons acquired during the operation of the target test train; and determine the missed detection rate of the beacons based on the traversal results.

[0051] Understandably, when the target test train is a tram, the operating environment of the tram is relatively harsh compared to the subway. Most of its track circuits are laid on the ground, and are always facing high and low temperature changes, wind, sand, soil and rocks, rain, acid and alkali corrosion and other harsh conditions. Therefore, problems such as beacon or loop equipment operation failures often occur. When the beacon loop fails, the positioning accuracy of the train will be greatly reduced. This affects the train monitoring module's ability to track the real-time position of the train, resulting in the phenomenon that the train's arrival time is uncontrollable. Based on this, the current test method generally implements the test of missed beacons by shielding one or more beacons.

[0052] Since a conventional station contains 4 to 8 beacons, and a train operation plan contains at least 30 stations, that is, during a train operation, it will pass through at least 200 to 240 signal devices, and the number of beacons increases exponentially with the increase in stations. If the current test method is used, it is easy to cause missed tests or repeated tests during the traversal process. Therefore, assuming that the missed test rate of a single beacon is 1%, and the missed test rate of two consecutive beacons is 2%, the following statistics are made:

[0053]

[0054]

[0055] To this end, the automatic control module can loop through the beacons according to the test requirements. Specifically, it loops through the statements corresponding to the beacons to complete the traversal test of all beacons, and logs and displays the traversal results to facilitate users to view them visually. This solves the problems of missed tests and retests in the manual test process. At the same time, it improves the execution efficiency of the tram beacon test process.

[0056] The rail transit test system provided by the above embodiment establishes a communication connection with the target test train through the automatic control module, and determines the running speed of the target test train according to the acquired configuration data and determines the target section to be used according to the location information of the target test train. When the forwarding server determines that the target section is in a clearing state, the automatic control module can control the target test train to perform a running car test in the target section according to the determined running speed. There is no need to manually adjust the running speed of the train and there is no need to manually control the occupancy and clearing status of the section, thereby avoiding the problem of speed mutation that occurs when the running speed of the train is manually adjusted, realizing automated running car testing, and thus improving the efficiency and convenience of the test.
