Description
Technical Field
The invention relates to the field of vehicle engineering, in particular to a train control method, device and system.
Background
The rail train is used as a main carrying vehicle in many cities due to the advantages of high driving punctuality rate, large passenger capacity and the like. A control system for a rail train generally comprises: the system comprises automatic train monitoring equipment, computer interlocking equipment, a zone controller, turnout equipment, axle counting equipment and a train operation protection device. The axle counting device is arranged on a train track, and the closed-loop sensor arranged on the train track is adopted to detect the number of passing pairs of train wheels, so that the occupied detection of the track is provided. And the axle counting equipment is connected with the computer interlocking equipment and is used for sending the track occupation detection result to the computer interlocking equipment.
The number of the zone controllers is multiple, and each zone controller is used for monitoring the train position in the jurisdiction area. The train operation protective devices arranged on the trains are in data communication with the zone controllers within the range of the trains, so that train position information is sent to the zone controllers. The regional controller sequences according to the position information sent by all trains in the jurisdiction region, then generates movement authorization information for each train and sends the movement authorization information to the corresponding train, so that the train operation protection device in the train adjusts the running speed of the train according to the movement authorization information, and the like, and the distance between the train operation protection device and the front and rear trains is ensured to be within a safe distance. The automatic train monitoring equipment is respectively connected with the computer interlocking equipment and the zone controller and is used for carrying out comprehensive processing according to train position information sent by the zone controller and train track occupation information sent by the computer interlocking equipment and then sending a command to the computer interlocking equipment to control the turnout equipment to act.
In the conventional control system, since there are a plurality of trains in the jurisdiction area of each zone controller, the real-time communication and operation contents of the zone controllers are more, and the operation capability of the zone controllers is called as a bottleneck of the control system. The number of trains that each zone controller can control is limited, and the number of zone controllers can be increased in order to ensure rapid and accurate monitoring of train positions. However, the problem is that the train passes through a plurality of jurisdictions during the running process, and train handover operation is performed between the area controllers in adjacent jurisdictions, so that the function of the control system is complex.
In addition, all train position information needs to be sent to the regional controller by the train operation protective devices in all trains, and after all trains in the jurisdiction area of the regional controller are sequenced, the regional controller generates movement authorization information for each train and then sends the movement authorization information to each train. Since a certain time is consumed for signal transmission, the zone controller generates the movement authorization information for each train, and a certain time is consumed, so that the processing efficiency of the control system is poor.

The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Example one
The embodiment provides a train control method, which can be executed by a train control device in a train operation protection device and can be realized in a software and/or hardware mode. The train operation protection devices are arranged on the trains, and the train operation protection devices arranged on the trains are connected with the regional integrated controller. Fig. 1 is a flowchart of a train control method according to an embodiment of the present invention. As shown in fig. 1, the train control method provided in this embodiment includes the following steps:
In this embodiment, a positioning device is provided on the current train, and is used to obtain the position information of the current train in real time. The positioning device may send the position information to the train operation guard.
And then, the train operation protection device can send the acquired current train position information to the regional integrated controller. The sending process may be periodically and actively sent by the train operation protective device, or may be sent to the regional centralized controller after receiving the location information request message sent by the regional centralized controller.
The regional centralized controller receives train position information sent by each train and train track occupation information generated by the axle counting equipment, and acquires the position information of each train. And the regional centralized controller sequences the trains according to the position information of the trains and generates a sequencing result. And then the regional centralized controller sends the sequencing result to the train operation protection device of the current train communicated with the regional centralized controller. The sequencing result comprises the running sequence of each train and the identity information of each train.
The regional centralized controller needs to be in communication connection with all trains, and the train operation protective devices in all trains send position information to the regional centralized controller so that the regional centralized controller sequences all trains. When a certain train loses communication connection with the regional centralized controller, the regional centralized controller can search train track occupation information sent by the axle counting device at the corresponding position according to the position information sent by the train in the last period, and accordingly, whether the train runs through the train track where the axle counting device is located is judged, the approximate position of the train is further known, and therefore the train sequencing is completed.
And 102, extracting the identity information of the front train adjacent to the current train from the sequencing result acquired by the regional centralized controller by the train operation protection device.
The sequencing result sent by the regional centralized controller contains the running sequence of each train and the identity information of each train. The identity information of the train can be train identification, communication address and the like, so that the train operation protection device in the current train can communicate with the front train according to the identity information.
And the train operation protection device of the current train extracts the identity information of the front train adjacent to the train operation protection device from the sequencing result.
And 103, communicating the train operation protection device with the corresponding front train according to the identity information of the front train to acquire the position information of the front train.
And the train operation protection device communicates with the corresponding front train according to the front train identity information to acquire the position information of the front train.

And step 104, controlling the current train to run and keep a safe distance with the front train by the train running protection device according to the current train position information and the position information of the front train.
The train operation protection device can control the running speed by combining the position information of the train operation protection device with the position information of the front train so as to keep a safe distance with the front train.

According to the technical scheme, the current train is communicated with the adjacent front trains to obtain the position information of the front trains, and then the trains are controlled to run according to the position information of the front trains, which is equivalent to the fact that the process of generating the movement authorization information in the prior art is executed by the train running protection device in the current train, and the movement authorization information is not generated by the regional integrated controller, so that the burden of the regional integrated controller is reduced, and the efficiency of the whole system is improved. Therefore, only one area centralized controller is needed in the whole train control system, one area centralized controller is communicated with all trains and sequences all the trains, and the problem that the system function is complex due to train handover between the area controllers in the prior art caused by the fact that trains cross areas is further solved.
In addition, compared with a mode of obtaining the location information in a centralized manner through a zone controller in the prior art, in this embodiment, the zone centralized controller only sequences trains, and the trains are directly communicated through train identity information included in a sequencing result to obtain the location information of adjacent trains, and do not need to be processed once through the zone controller, so that the communication speed is higher, and the speed of processing the location information is higher.
