[0036] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the accompanying drawings of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0037] The present application will be described below with reference to the accompanying drawings. Figures 1-3 The train safety operation method and device of the platform area of the present application are described.
[0038] Figure 1 is a flowchart of a train safety operation method provided by the present application, as shown in Figure 1 the train safety operation method is applied to an automatic train protection system ATP, and includes the following steps:
[0039] Step 110, obtaining a first safety envelope of a train running in a full automatic mode FAM or a peristaltic mode CAM, the safety envelope including safety position information of the train.
[0040] In this step, the safety position information of the train includes a minimum safety front end, a maximum safety front end, a minimum safety rear end, a maximum safety rear end, a predicted safety rear end and a predicted safety front end.
[0041] In this embodiment, when the train is running in a normal section in the FAM or CAM mode, the on-board ATP (Automatic Train Protection) calculates the safety envelope of the train according to normal conditions.
[0042] Step 120, sending the first safety envelope to a zone controller ZC, and receiving a train movement authority corresponding to the first safety envelope sent by the ZC.
[0043] In this step, the onboard ATP sends the calculated safe position of the train to the ZC (Zone Controller), and the ZC calculates the movement authorization (MA) for the train.
[0044] In this embodiment, ZC can calculate the MA of the following train in real time based on the first security envelope sent, with the calculated minimum safe back end of this train as the endpoint of the movement authorization.
[0045] Step 130: When the train's safety envelope enters the platform area, add a target envelope to the target location information in the first safety envelope to obtain a second safety envelope; wherein, the target location information includes the location information of the maximum safe front end and the location information of the maximum safe back end in the first safety envelope, and the target envelope is determined based on the train's running speed, train deceleration rate, train length, platform length, and the location of the operating stop.
[0046] In this step, the target envelope can be the front envelope.
[0047] In this step, the determination of the target envelope is related to the train's operating status and the train's operating route. For example, it is related to the train's operating speed, communication delay, whether there are obstacles on the operating route, and whether it exceeds the range of two adjacent axles in the train's operating section. It is also related to the train's deceleration rate, train length, platform length, and the location of the operating stop.
[0048] In this embodiment, the range corresponding to the second safety envelope of the train shall not exceed the occupied range of the two adjacent axles in the current section of the train.
[0049] In this embodiment, after obtaining the second safety envelope, the distance between the maximum safe front end and the maximum safe back end (minimum safe front end and minimum safe back end) of the train is consistent with the actual length of the train. The actual position of the train head is sufficiently far from the movement authorization endpoint calculated by ZC, thereby ensuring that the train does not cause dangerous consequences due to overstepping the signal and ensuring the safety of train operation.
[0050] In this embodiment, when the train is at a station, the target envelope can be set at the maximum safe front end and the maximum safe back end of the train. When the train performs a backward jump, the target envelope can be set at the minimum safe front end and the minimum safe back end of the train. That is, by flexibly setting the target envelope at different safe ends of the train, the movement authorization calculated by ZC is always within the safe range.
[0051] In some embodiments, the train safety envelope during the backward jump can be enhanced by adding a "rear envelope" to ensure the safety of the train and the following trains during the jump while maximizing operational efficiency.
[0052] Figure 2 is a schematic diagram of safety envelope calculation in a train entering a station process provided by the present application, in which Figure 2 In the embodiment shown, when the train enters the platform, the first safety envelope of the train is formed by the minimum safety rear end and the maximum safety front end of the train, wherein the positioning uncertainty is respectively between the minimum safety front end and the maximum safety front end of the train and between the minimum safety rear end and the maximum safety rear end of the train, a new front envelope (i.e. a target envelope) is added at the positions of the maximum safety rear end and the maximum safety front end to form a new maximum safety rear end and a new maximum safety front end; the third safety envelope is formed from the minimum safety rear end to the new maximum safety front end.
[0053] The station area train safety operation method provided by the embodiment of the present application can increase the safety of train entering and stopping in the station, reduce the probability of accidents caused by train entering the signal, and improve the safety of train operation by changing the safety envelope calculation method in the process of entering the station.
[0054] In some embodiments, after receiving the train movement authorization corresponding to the first safety envelope sent by the ZC, the method further includes: in the case that the train performs a backward jump operation, adding a target envelope to the position information of the minimum safety front end and the position information of the minimum safety rear end in the first safety envelope to obtain a third safety envelope; determining the movement authorization of the subsequent train based on the third safety envelope.
[0055] In this embodiment, the target envelope can also be a rear envelope.
[0056] In this embodiment, when the train passes a certain distance from the warning post, the train will perform a backward jump operation. During the jump process, the on-board ATP will add a "rear envelope" to the position information of the minimum safety rear end and the minimum safety front end based on the first safety envelope to obtain a third safety envelope. The on-board ATP sends the calculated position information to the ZC, and the ZC calculates the MA of the subsequent train with the calculated minimum safety rear end of the train as the end point of the movement authorization to ensure that the train can jump without danger and also ensure the operation efficiency of the subsequent train.
[0057] Figure 3 is a schematic diagram of safety envelope calculation in a train jump process provided by the present application, in which Figure 3In the shown embodiment, when the train performs the backward jump operation at the platform, the first safety envelope of the train is formed by the minimum safety rear end and the maximum safety front end of the train, and the positioning uncertainty is between the minimum safety rear end and the maximum safety front end and between the minimum safety front end and the maximum safety front end, respectively, a new rear end envelope (i.e., a target envelope) is added at the position of the minimum safety rear end and the minimum safety front end to form a new minimum safety rear end and a new minimum safety front end, and the new minimum safety rear end to the maximum safety front end forms a third safety envelope.
[0058] In this embodiment, the range of the third safety envelope does not exceed the measurement range of the two adjacent axles in front of and behind the area where the platform is located.
[0059] The platform area train safety operation method provided by the embodiment of the application adds a target envelope to the position information of the minimum safety front end and the position information of the minimum safety rear end in the first safety envelope when the train performs the backward jump operation, obtains a third safety envelope, and calculates the movement authority of the subsequent train according to the third safety envelope, so as to ensure the safety of the train when performing the backward jump operation.
[0060] In some embodiments, after the second safety envelope is obtained, the method includes: canceling the equipment of the protection section outside the platform area.
[0061] It can be understood that, when the safety envelope of the train after entering the station is too small, in order to prevent the train from advancing into the signal and causing dangerous consequences, a separate protection section can be additionally arranged outside the platform, and the protection section is locked when the entry route of the train is opened.
[0062] In this embodiment, the new front end envelope or rear end envelope is added on the basis of the first safety envelope, so that the new safety envelope exceeds the actual length of the train, so that the actual train head position has a sufficient distance from the movement authority end point calculated by the ZC, thereby ensuring that the train does not cause dangerous consequences due to advancing into the signal, and at this time, the protection section outside the platform is canceled, thereby reducing the use amount of the axle counter equipment, and further improving the operation efficiency to a certain extent.
[0063] The platform area train safety operation method provided by the embodiment of the application cancels the equipment of the protection section outside the platform area after the second safety envelope is obtained, thereby reducing the use amount of the axle counter equipment and improving the train operation efficiency.
[0064] In some embodiments, after the second safety envelope is obtained, the method further includes: clearing the second safety envelope when the train is parked and stable; or, after the third safety envelope is obtained, the method further includes: clearing the third safety envelope when the train is parked and stable.
[0065] In the embodiment, the train entering the station and stopping and the train performing the jump when the train fails to align with the mark are all possible situations of safety accidents, and therefore the first safety envelope of the train is updated according to the above situations, and the updated safety envelope is cleared when the train leaves the platform track, so as to meet the safety requirements of the train running on different platform tracks.
[0066] In the embodiment, when the train stops and stabilizes, the previous second safety envelope or third safety envelope is cleared, and when the train restarts, the train is calculated according to the first safety envelope calculation method of the ATP until the next platform track is entered, the second safety envelope or the third safety is reacquired, and the processing is repeated in turn.
[0067] The platform area train safety operation method provided by the embodiment of the application clears the second safety envelope or the third safety envelope when the train stops and stabilizes after the updated train movement authority is obtained, so as to meet the safety requirements of the train running on different platform tracks, and the safety of the train in automatic driving is improved.
