Abstract
The invention discloses a ZC safety protection method for evacuating passengers when an unmanned train abnormally opens a door, which comprises the following steps: defining in the database of ZCs: a personnel evacuation activation region and a corresponding personnel evacuation protection region; unexpected door opening occurs in the stop state of the train, and a passenger protection request is sent to ZC by CC; the ZC judges a personnel evacuation activation region where the current train is located according to the passenger protection request and the position of the train, and activates the corresponding personnel evacuation protection region; and the ZC takes the activated personnel evacuation protection area as a reserved or authorized barrier to all communicated trains to prevent the trains from moving. The invention establishes a protection area to ensure the safety of other running trains and evacuating passengers in the uplink and downlink directions.
Description
Technical Field
The invention relates to the field of rail transit, in particular to a Zone Controller (ZC) safety protection method in the process of evacuating passengers when an unmanned train is abnormally opened.
Background
In the conventional CBTC (Communication Based Train Control) system, when a Train is stationary, a door of the Train is opened to evacuate people after the Train stops due to smoke, fire and the like. Other trains pass through the evacuation area in the uplink and downlink directions, and safety risks exist when passengers escape.
Disclosure of Invention
The invention aims to provide a ZC safety protection method for evacuating passengers when an unmanned train is abnormally opened, which is used for establishing a protection area and ensuring the safety of other running trains and evacuated passengers in the uplink and downlink directions.
The technical scheme for realizing the purpose is as follows:
the ZC safety protection method for evacuating passengers when the unmanned train opens the door abnormally comprises the following steps:
defining in the database of ZCs: a personnel evacuation activation region and a corresponding personnel evacuation protection region;
unexpected door opening occurs in the stop state of the train, and a passenger protection request is sent to ZC by CC;
the ZC judges a personnel evacuation activation region where the current train is located according to the passenger protection request and the position of the train, and activates the corresponding personnel evacuation protection region;
and the ZC takes the activated personnel evacuation protection area as a reserved or authorized barrier to all communicated trains to prevent the trains from moving.
Preferably, the method further comprises the following steps:
after the personnel evacuation protection area is activated, the ZC sends the activated personnel evacuation protection area to the central control system;
after finishing dispersing passengers in the personnel evacuation protection area, the ZC cancels the activation of the personnel evacuation protection area according to a command of canceling the passenger evacuation protection of the central control system.
Preferably, when the ZC determines that the current train is in the personnel evacuation activation region, the ZC performs comprehensive judgment by combining the passenger protection request, the train position and the trackside database.
Preferably, the ZC cancels activation of the people evacuation protection zone according to a command to cancel passenger evacuation protection and a secondary confirmation command of the central control system.
Preferably, in the database of ZC, a personnel evacuation activation area and a personnel evacuation protection area are defined on a track area on the train traveling route.
The invention has the beneficial effects that: in the invention, a CC (Car Controller) sends a personnel protection request to a ZC (ZC), and the ZC establishes a certain protection zone according to the request of a train. The protection zone is used as an authorized barrier of other controlled trains/uncontrolled trains, thereby ensuring the safety of other running trains and evacuating passengers in the uplink and downlink directions. And on the central control system, the personnel evacuation protection interval can be clearly seen, and the influence on which operation trains is caused.
Drawings
FIG. 1 is a flow chart of the ZC safeguard method for passenger evacuation when an unmanned train is abnormally opened according to the invention;
fig. 2 is a case where the personnel evacuation activation area and the personnel evacuation protection area are consistent in the present invention;
fig. 3 shows a situation in which the people evacuation activation area and the people evacuation protection area do not coincide in the present invention.
Detailed Description
The invention will be further explained with reference to the drawings.
Referring to fig. 1, the ZC safety protection method for passenger evacuation when an unmanned train opens an door abnormally according to the present invention includes the following steps:
step one, defining in a database of a ZC: people evacuation activation zone and corresponding people evacuation protection zone, namely: a personnel evacuation activation area and a personnel evacuation protection area are defined on a track area on a train running route. As shown in fig. 2 and fig. 3, the situation is that the people evacuation activation region and the people evacuation protection region are consistent, and the situation is that the people evacuation activation region and the people evacuation protection region are inconsistent. In fig. 3, a region 1 is a person evacuation activation region, and a region 2 is a person evacuation protection region.
Step two, unexpected door opening occurs in the stop state of the Train, the CC generates a passenger protection request to the ZC in the Train under the protection of ATP (automatic Train protection) generally.
And step three, the ZC judges the personnel evacuation activation area where the current train is located according to the passenger protection request and the position of the train and by combining a trackside database, and activates the corresponding personnel evacuation protection area.
And step four, the ZC takes the activated personnel evacuation protection area as a reserved or authorized barrier to all the communication trains of the ZC to prevent the trains from moving.
And step five, after the personnel evacuation protection area is activated, the ZC sends the activated personnel evacuation protection area to the central control system.
And step six, after the passengers in the personnel evacuation protection area are completely evacuated, the ZC cancels the activation of the personnel evacuation protection area according to the command of canceling the passenger evacuation protection of the central control system. In particular, it can be provided that: the ZC can cancel the second confirmation command. The method and the device prevent the release of the personnel evacuation protection interval which is not released due to the mistaken command of the scheduling personnel.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
