Current-receiving conversion automatic control method of metro vehicle

Abstract

The invention relates to a current-receiving conversion automatic control method of a metro vehicle. The method comprises the following steps that the feasibility of switch is judged by TCMS accordingto vehicle location information; the vehicle activation, zero speed signal and current current-receiving enable signal are combined to give an operational interface by TCMS; an instruction is given to the LCU after driver's operation, and the LCU can complete the current-receiving conversion according to the specified process (including descending a boot or bow, descending a pantograph / current-receiving boot to judge the position, selecting the pantograph / current-receiving boot mode, enabling the pantograph / current-receiving boot to judge, ascending the pantograph / current-receiving boot, ascending the pantograph / current-receiving boot to judge the position, judging the high voltage, enabling assistant inverse and the like). If the previous conditions aren't met in the conversion process,the conversion process is interrupted, and two current-receiving modes in the conversion process have strict interlocking logic so as to ensure the safety of the vehicle current receiving. According to the scheme, the operation is simple, the conversion process is timely and reliable, and the efficiency of vehicles in and out of the warehouse is improved.

Description

technical field [0001] The invention relates to a flow receiving conversion control method, and belongs to the technical field of subway vehicle train network control systems. Background technique [0002] At present, the current receiving methods of subway vehicles are mainly pantograph and current receiving shoes. Usually, the vehicles only use one current receiving method, and the catenary power supply can run through the whole line, but the three-rail power supply method is limited to the depot due to safety considerations. Usually, the three-rail system is no longer arranged, so the trains in the depot need to be powered by the trolley lines. This method requires manual operation, and the operation is cumbersome. When entering and leaving the depot, the cooperation of the people under the train is required. In addition, there are also cases where the trolley lines break due to the driver’s mistaken movement of the train. [0003] Some subway vehicles will consider batte...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to comprehensively consider the safety in the operation process from the specific position of current receiving conversion, high voltage isolation, conversion process, current receiving state judgment, etc., and the driver needs to follow a fixed operation process, the vehicle circuit design is relatively complicated, and the operation process is cumbersome

It is difficult to control each time node in this process. Due to the influence of the unfixed action time of mechanical devices, the maximum time-consuming situation of each process operation needs to be considered, which affects the time for vehicles to enter and leave the warehouse, and the efficiency of receiving and dispatching vehicles is low.
