Problems solved by technology

The object of the present invention is to provide a method and system for judging the direction of a locomotive in view of the above-mentioned deficiencies in the prior art, so as to realize the precise judgment of the running direction of the locomotive, and to avoid faults caused by misoperation of the direction handle by the driver during the running of the locomotive. During the remote wireless operation of heavy-duty locomotives, it solves the problem of parking for stand-alone operation, improving train operation safety and transportation efficiency

Embodiment Construction

[0042] Such as figure 1 As shown, the method for judging the direction of the locomotive includes:

[0043] Step 1, at the moment of starting the locomotive, the network control system 1 determines the direction signal F0 at the moment of starting the locomotive by acquiring the position signal of the direction handle 2;

[0044]Step 2, during the operation of the locomotive, the traction control unit 3 acquires the direction signal F1 when the locomotive is running and sends it to the network control system 1; the network control system 1 acquires the direction signal F2 corresponding to the position signal of the direction handle 2 when the locomotive is running ;

[0045] Step 3, the network control system 1 judges whether F1 and F2 are consistent, and if so, determines F2 as the direction signal when the locomotive is running; if not, determines F0 as the direction signal when the locomotive is running.

[0046] The above method can prevent the driver from mishandling th...

Abstract

The invention discloses a locomotive direction judgment method and system, and the method comprises the steps that a network control system determines a direction signal F0 of a locomotive at a starting moment by obtaining a position signal of a direction handle at the starting moment of the locomotive; in the running process of the locomotive, a traction control unit acquires a direction signal F1 during running of the locomotive and sends the direction signal F1 to the network control system; the network control system acquires a direction signal F2 corresponding to a direction handle position signal when the locomotive runs; the network control system judges whether F1 is consistent with F2 or not, and if YES, F2 is determined as a direction signal when the locomotive runs; and if NO, F0 is determined as a direction signal when the locomotive runs. Accurate judgment of the running direction of the locomotive can be achieved, faults caused by direction judgment errors due to misoperation of a direction handle by a driver in the running process of the locomotive are avoided, the problem that in the remote wireless running process of the heavy-load locomotive, parking is needed fordecompilation single-machine operation is solved, the parking probability is reduced, and the train running safety and the transportation efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a method and system for judging the direction of a locomotive. Background technique [0002] The running direction of the locomotive is the key signal for locomotive control, which is used for traction motor traction force, braking force, anti-skid and anti-idling control, etc. [0003] If the running direction judged by the locomotive is inconsistent with the actual running direction of the locomotive, it will cause overcurrent of the traction motor, overcurrent of the inverter, and even burnout of the traction motor and converter. Therefore, it is very important to ensure the correctness of locomotive direction judgment for locomotive control. [0004] At present, the judgment logic of the mainstream locomotive direction is as follows: [0005] 1) When the locomotive is started, the driver operates the direction handle on the control end to select the "forwar...
