A control system and a control method for traction motors of motor train carriages

Abstract

The present invention provides a control system for traction motors in carriages of motor vehicles, which is characterized in that: it includes a locomotive control module and a plurality of carriage control modules; it also provides a control method according to the above control system, which is characterized in that: The module transmits the current speed signal to the head control module, the head control module processes all the received current speed signals and sends the compensated speed signal to the corresponding car control module, each car control module will compensate the speed signal, given The speed signal and the current speed signal are superimposed to obtain a speed deviation signal, and the speed of the traction motor is adjusted according to the speed deviation signal. Adopting the control system and method described in the present invention can effectively reduce and avoid the collision between carriages, thereby reducing the damage of connecting parts of the carriages and improving the safety performance of the train, and can be used for trains using different types of traction motors, which facilitates the flexibility of trains marshalling to improve the efficiency of train operation.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a control system and a control method for a traction motor of a train carriage. Background technique [0002] There is usually a bogie at both ends of each car of the motor car, and the two bogies are connected by an axle. There are two wheel sets on each bogie, and each wheel set has two wheels. The traction motor of the bullet train is installed on the bogie, the rotating shaft of the traction motor is connected with the wheel shaft on the bogie through the transmission, and each wheel pair is driven by a traction motor. Therefore, there are 4 traction motors driving the wheels of 4 wheel pairs in one bullet train carriage. In addition, there is a coupler connection between the carriages of the motor car. The coupler not only plays the role of connecting the carriages, but also keeps a certain distance between the carriages, and at the same time plays the role of transm...

Problems solved by technology

[0004] Aiming at the problem of the background technology, the present invention provides a control system for the traction motor of the train compartment, and also provides a control method for the above-mentioned control system, so as to solve the problem that the traction motors in the train compartments are out of sync due to the speed difference between the compartments and the traction motors. Collisions between carriages will damage the connecting parts of the carriages, increase operating costs, endanger the safety performance of the train, and affect the normal operation of the train
