Problems solved by technology

At the same time, there must be perfect backup braking measures, because trams are generally equipped with a braking control system, once a failure occurs, it means that "all" braking systems have failed, so there must be a perfect backup braking system measures to secure parking

Abstract

The invention relates to an urban tram braking system. The system comprises a braking instruction generation system, a braking control system and an anti-skid system, wherein the braking instruction generation system comprises a braking electronic control unit (BECU) and a braking control unit (BCU) and sends a braking instruction to the BECU; the BECU calculates required braking force according to the braking instruction and loading force detected by a loading pressure sensor and provides the braking force for a traction control unit; the traction control unit feeds a dynamic braking force signal back to the BECU; the BECU calculates air braking force which is needed to be supplemented and controls the BCU to generate braking cylinder pressure so as to realize braking control; the braking instruction generation system is provided with a driver controller, an emergency braking switch and a logic control unit connected with the emergency braking switch; the anti-skid system comprises a speed sensor arranged on a wheel axle and an anti-skid exhaust valve arranged on a braking cylinder pipe; the speed sensor detects a speed signal and transmits the speed signal to the BECU; and the BECU controls the action of the anti-skid exhaust valve according to the speed signal.

Description

technical field [0001] The invention relates to a braking control device for electric vehicles, in particular to a braking system for trams comprising a braking command generating system, a braking control system and an anti-skid system. Background technique [0002] Looking at all modern metropolises in the world, all of them take the development of urban rail transit as the foundation. Through the combination of urban rail transit and inter-city rail transit, railway trunk line passenger transport, road passenger transport, port shipping, and air transport, a large and convenient transportation network is formed, which is the model of modern large-scale transportation and the development direction of our country. [0003] With the rapid development of economy, our country has entered into the accelerated development stage of urbanization and urban transportation. With its advantages of large capacity, high efficiency, and low pollution, urban rail transit has quickly beco...
