Problems solved by technology

[0010] Based on the above requirements, the urban rail anti-skid control system must have high reliability for the control function, anti-skid monitoring function and anti-skid failure protection function. If the anti-skid control module has an abnormal anti-skid control, it may cause the air braking force to continue to decrease or even disappear. , thereby affecting vehicle safety
In the current anti-skid control system, functional circuits such as anti-skid failure protection and anti-skid valve drive are usually independent of each other. Each circuit is composed of discrete components. The reliability is not high; when a fault occurs, the location of the fault point cannot be realized, which is not conducive to the maintenance and repair of on-site equipment

Abstract

The invention discloses an anti-slide control device for an urban rail braking system. The anti-slide control device comprises a main control module and an anti-slide valve driving module, wherein the main control module is used for receiving a speed signal of an axle and a braking instruction, generating a corresponding valve driving signal, a control signal and a life signal, outputting the signals to the anti-slide valve driving module and judging an operation state of the anti-slide valve driving module according to a feedback signal, wherein the life signal is used for showing whether the operation is abnormal or not; the anti-slide valve driving module is used for driving an anti-slide valve and comprises a valve driving unit, an exhaust valve protecting unit and a relay unit control unit; the valve driving unit, the exhaust valve protecting unit and the relay unit control unit are connected with each other in sequence; the valve driving unit is used for receiving the valve driving signal, driving the anti-slide valve and transmitting the feedback signal; the exhaust valve protecting unit is used for outputting an anti-slide failure protection triggering signal; and the relay control unit is used for controlling an electric state of a relay. The anti-slide control device for the urban rail braking system, disclosed by the invention, is advantaged in that the structure of the device is simple and compact; reliability and safety in the anti-slide control are high; the device is flexible to control; and fault monitoring and positioning can be achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail braking, in particular to an anti-skid control device for an urban rail braking system. Background technique [0002] With the acceleration of the urbanization process, more and more people are looking for a more convenient and environmentally friendly way of travel. Urban rail transit is favored due to its convenience, greenness and environmental protection. The operation of urban national road trains is different from that of main line railway vehicles. It requires frequent starting, speed regulation and braking, which puts forward higher requirements on the performance of the vehicle braking system. In order to meet the actual needs of resource-saving and environment-friendly social construction, the braking system used in urban rail transit vehicles needs to use electric braking as much as possible, so that certain economic benefits can be generated through energy recovery, and It can redu...
