At present, the automation level (Grade of Automation, goA) of the full-automatic unmanned is divided into five levels of GoA 0-GoA 4, when the full-automatic unmanned meets the GoA4 level, a driver is not on duty in a cab of a train during driving, and when a line is abnormal, a dispatcher of a central dispatching workstation is required to remotely execute operation so as to perform fault removal and operation recovery.

In view of the above problems, the present application provides a method and an apparatus for testing a remote driving restriction mode of a train, which mainly aims to realize a method for testing a train to apply for an RRM mode and execute an RRM function when the train loses positioning due to an abnormal line and cannot continue full-automatic unmanned driving.
In order to solve the technical problems, the application provides the following scheme:

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
With the continuous development of technology, urban rail transit also advances towards intelligentization and automation, such as full-automatic unmanned technologies (Full Automaitc Mode, FAM), and full-automatic unmanned technologies have become an indispensible development trend of future urban rail transit. At present, the automation level (Gradeof Automation, goA) of the full-automatic unmanned is divided into five levels of GoA 0-GoA 4, when the full-automatic unmanned meets the GoA4 level, a driver is not on duty in a cab of a train during driving, and when a line is abnormal, a dispatcher of a central dispatching workstation is required to remotely execute operation so as to perform fault removal and operation recovery.
When the train loses position due to abnormal line, the train cannot continue full-automatic unmanned operation, so that the train can enter a remote limit driving mode (RemoteRestricted train operating mode, RRM) which is a degraded full-automatic operation mode for ensuring the safe operation of the train, and the fault removal and the recovery operation can be carried out in the RRM mode. However, before the system is put into use, in order to ensure the safe execution of the function, a test is required first, but the existing test methods are all related to the test conditions when manual driving loses positioning, and no test method for applying RRM mode and executing RRM function by the train when the train loses positioning due to abnormal line is present. Therefore, the application provides a test method for a train remote limit driving mode. The specific implementation steps are shown in fig. 1, including:
101. and under the condition of beacon fault test, acquiring beacon variable information.
In this step, the route of the train on the running line can be determined according to the interlock, at this time, the train normally runs in the section in the FAM mode, and when the train normally runs in the FAM mode, the train communication network is normal, the train performs continuous train-ground wireless bidirectional communication, the rear train tracks the front train according to the automatic protection position (Automatic Protection, AP) of the front train, that is, the position of the rear end, and the AP rear end of the front train moves according to the displacement of the train, thereby shortening the safe running interval of the train. In this process, the in-vehicle Controller (CarborneController, CC) and the Zone Controller (ZC) periodically communicate with each other.
Specifically, when the CC runs on the train, the beacon on the line can be continuously read to obtain the positioning Of the train, the positioning report Of the train is sent to the ZC, the ZC can calculate the End Of Authority (EOA) in real time by combining the positioning report through the trackside information provided by the interlocking, the trackside information and the calculated EOA are sent to the vehicle-mounted CC, and then the CC sends the positioning report Of the train to the ZC according to the EOA provided by the ZC, so that the information interaction between the ZC and the CC is completed.
The number of beacons that are simulated to be lost may then be determined in front of the train's travel route based on the length of the track that the train is traveling and the principle of beacon installation, after which the simulated train continuously loses a corresponding number of beacons. Further, in a specified communication period, that is, a communication period between the ZC and the CC, the vehicle-mounted CC may continuously read the beacon, so that the vehicle-mounted CC may also read the beacon variable information after simulating to continuously lose a plurality of beacons in this step. Therefore, the execution subject of the present application is an in-vehicle CC.
102. Under the condition of train stopping fault test, determining the restarting condition of the vehicle-mounted controller.
Step 102 and step 101 are in parallel relation, and are both one of test cases of a train remote limiting driving mode, in this step, the train is stopped in a section in a FAM mode, and meanwhile, the train stops in a non-memory positioning area of the stopping section, namely, a train stopping fault, at this time, a dispatcher can remotely restart the vehicle-mounted CC on a central dispatching workstation, so that the restart condition of the vehicle-mounted controller can be determined in this step.
103. And determining whether the beacon variable information is that a plurality of beacons are continuously lost, and whether the restarting condition of the vehicle-mounted controller is that the restarting is completed.
After the beacon variable information is obtained in the steps 101 and 102 and the restarting condition of the vehicle-mounted controller is determined, the vehicle-mounted CC can determine whether the read beacon variable information is a normal beacon or a plurality of beacons are continuously lost in the step; meanwhile, the vehicle-mounted CC can also confirm the restarting condition.
If the beacon variable information read by the vehicle-mounted CC is a plurality of beacons which are continuously lost under the condition of beacon fault test; step 104 may be performed if the on-board controller completes the restart in the event of a train stop failure test.
104. And determining that the train loses positioning information, and controlling the train to switch from the full-automatic unmanned mode to the remote limiting driving mode.
Under the condition of beacon fault test, the variable information of the beacons read by the vehicle-mounted CC is that a plurality of beacons are continuously lost; under the condition of train stopping fault test, the vehicle-mounted controller completes restarting, and the train can be considered to lose positioning information under both conditions.
When the beacon variable information read by the vehicle-mounted CC is that a plurality of beacons are continuously lost, the vehicle-mounted CC triggers the emergency braking of the train, the train stops in an interval and is out of position, at the moment, the train cannot continue to run in a full-automatic unmanned mode, and the train needs to be converted into a remote limiting driving mode; after the vehicle-mounted controller is restarted and the related devices of the train are subjected to self-inspection, the train loses positioning, cannot continue to run in a full-automatic unmanned mode and needs to be converted into a remote limiting driving mode.
It should be noted that the two test cases are in parallel relationship, but the operation flow of the train in the full-automatic unmanned mode to the remote limiting driving mode is the same in the two test cases.
Based on the implementation manner of fig. 1, it can be seen that the method for testing the remote driving limiting mode of the train provided by the application is divided into two testing cases, one is a testing case when a beacon is lost, namely a beacon fault, and the other is a testing case when the train stops, wherein the train stops when the train stops, and the train does not stop in a memory section. Because beacon variable information is generated under the condition of beacon fault or normal, the beacon variable information can be acquired firstly under the condition of beacon fault test of the application; meanwhile, because the vehicle-mounted controller should restart when the train stops, under the test condition of the train stop fault, the restart condition of the vehicle-mounted controller can be obtained, then whether the beacon variable information is a plurality of continuously lost beacons or not can be determined, whether the restart condition of the vehicle-mounted controller is restart completion or not can be determined, if the beacon variable information is a plurality of continuously lost beacons under the test condition of the beacon fault, the vehicle-mounted controller can be determined to lose positioning information under the test condition of the train stop fault and restart completion, and the train can be controlled to enter a remote limiting driving mode, so that the test of the remote limiting driving mode of the train is completed. After the train loses positioning information caused by different abnormal scenes, the condition that the train enters a remote driving limiting mode is covered, and the testing quality is ensured on the basis of improving the testing integrity.
Further, as a refinement and expansion of the embodiment shown in fig. 1, the embodiment of the present application further provides another method for testing a remote limited driving mode of a train, as shown in fig. 2, which specifically includes the following steps:
201. and under the condition of beacon fault test, acquiring beacon variable information.
202. Under the condition of train stopping fault test, determining the restarting condition of the vehicle-mounted controller.
203. And determining whether beacon variable information is a plurality of beacons which are continuously lost and whether the restarting condition of the vehicle-mounted controller is that the restarting is completed.
The implementation manners of step 201 to step 203 are the same as those of step 101 to step 103, and the same technical effects can be achieved, so that the same technical problems are solved, and the description thereof will not be repeated here.
204. And determining that the train loses positioning information, and controlling the train to switch from the full-automatic unmanned mode to the remote limiting driving mode.
In this step, the vehicle-mounted CC may send the train loss positioning information to the ZC, and after receiving the train loss positioning information, the ZC may obtain the stimulus device detection state and the maximum movement authorization endpoint (designated authorization endpoint) in the train running direction, and then may calculate the safety positioning information of the train according to the stimulus device detection state and the maximum movement authorization endpoint in the train running direction, and provide safety protection for the train. After the ZC calculates the safety positioning information of the train and puts forward the safety protection, the ZC can send the safety positioning information to the vehicle-mounted CC, and the CC can obtain the safety protection at the same time.
Meanwhile, the vehicle-mounted CC can send the train loss positioning information to the central dispatching workstation, and the central dispatching workstation can alarm the train loss positioning application after finishing the train loss positioning information, authorize the train to enter a remote limiting driving mode and send authorization information to the vehicle-mounted CC.
After receiving the safety positioning information of the train and the authorization information of the central dispatching workstation, the vehicle-mounted CC can send a mode signal for entering a remote driving limiting mode to the train according to the safety positioning information of the train and the authorization information of the central dispatching workstation, and after receiving the mode signal, the train can be switched to the remote driving limiting mode in a full-automatic unmanned mode. And when the train enters the remote limit driving mode, the vehicle-mounted CC can feed back that the train has entered the RRM mode to the central dispatching station.
Meanwhile, the current driving mode of the train is displayed as an RRM mode on a human-machine interface unit (Driver-Machine Interface, DMI).
205. When the train runs at a specified speed in the remote limit driving mode, a continued operation mode of the train is determined.
When the train is switched to the remote driving limiting mode, the train can run at a specified speed in the remote driving limiting mode, the optimal speed can be lower than 25KM/h, and during running, the vehicle-mounted CC can read the repositioning beacons in the running direction of the train again, obtain a reading result and determine the continuous running mode of the train according to the reading result.
When the reading result is that the relocation beacon is successfully read, the vehicle-mounted CC acquires the current location of the train and sends the current location to the zone controller, the zone controller ZC calculates a target movement authorization terminal of the train according to the current location, namely a new movement authorization terminal, the ZC can send the movement authorization terminal to the vehicle-mounted CC after calculating the new movement authorization terminal, and the process can be understood as a new round of communication between the CC and the ZC. The vehicle-mounted CC can send a mode signal for entering a full-automatic unmanned mode to the train according to the target movement authorization terminal point, the train can enter the full-automatic unmanned mode after receiving the mode signal, and continuously operates to the next platform for accurate parking in the full-automatic unmanned mode, and the vehicle door and the shielding door are automatically opened.
When the reading result is that the repositioning beacon is not successfully read, the train can be controlled to continue to run to the next station in the RRM mode, a driver enters a cab after stopping at the next station, the door and the shielding door are manually intervened to open, and the train is withdrawn from operation after the completion of the passenger.
