Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] figure 1 It shows that Embodiment 1 of the present invention provides a method for judging the state of a signal machine in front of a CBTC-level train in interconnection, including:

[0044] S11. Receive train control information sent by the regional controller, where the train control information includes protection section validity information and train stop position information.

[0045] In this step, it should be noted that the on-board equipment controller communicates with the regional controller to receive train control information sent by the regional controller. In the embodiment of the present invention, the train control information needs to contain di...

Abstract

The invention provides a method for judging the state of a front annunciator of a train. The method includes the steps that train control information sent by a zone controller is received; traveling position information of the train is obtained; a first protection distance and a second protection distance are obtained according to protection zone section effectiveness information, the traveling position information and train stopping position information; and the state of the front annunciator of the train is judged according to the first protection distance and the second protection distance.The method and device for judging the state of the front annunciator of the train are provided, the protection zone section effectiveness information and the train stopping position information whichare sent by the zone controller are received, and the first protection distance and the second protection distance are obtained according to the protection zone section effectiveness information, thetraveling position information and the train stopping position information; and the state of the front annunciator of the train is judged according to the first protection distance and the second protection distance, and the purpose that the state of the front annunciator of the train can be accurately and quickly recognized in interconnection and intercommunication is achieved.

Description

technical field [0001] The invention relates to the technical field of rail train operation, in particular to a method for judging the state of a signal machine ahead of a train in interconnection. Background technique [0002] During the operation of the train, it is necessary to realize the function of the wrong departure of the on-board ATP red light, that is, when the train is running in CM, AM, AR mode, not in the open mode, the current speed is zero, and it is stopped at the parking point of the wrong departure of the red light , if it is judged that there is a red light ahead, set the trigger speed of the emergency brake to 0 to ensure that the train will not run through the red light. At the same time, it is necessary to realize the screening of parking spots by ATO, that is, if the train is in AM mode, whether the ATO stops at the section parking spot or not, it is necessary to judge the traffic light status of the signal machine ahead. If it is a green light, the ...
