A multi-point data acquisition device for truck air brake

Abstract

The invention discloses a truck air brake multi-point data acquisition device. The multi-point data acquisition device is arranged between a main valve and an intermediate of a truck and used for acquiring the pressure change situations of a train pipe, the upper stream of a brake cylinder and an auxiliary air cylinder of a truck air brake in the braking and easing processes. The multi-point data acquisition device is provided with a multi-point data acquisition body and a circuit board with pressure sensors. The circuit board is installed on the multi-point data acquisition body. A plurality of acquisition holes are formed in the multi-point data acquisition body. The multi-point data acquisition body is connected with a multi-point data acquisition base, and the multiple acquisition holes in the multi-point data acquisition body communicate with pressured air inside a braking system. The multiple pressure sensors on the circuit board are arranged in the corresponding acquisition holes. The circuit board converts the pressure value acquired by the multiple pressure sensors into digital signals which are stored in a memorizer of a truck-mounted device. The truck air brake multi-point data acquisition device is capable of providing reliable real-time data for searching unusual-brake trucks and easing poor trucks and trucks induced by train unexpected emergencies, and thus the truck running safety is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, in particular to a multi-point data acquisition device for air braking of freight cars. Background technique [0002] None of the existing train air brake systems is equipped with a device for collecting pressure changes at key points during the braking and release process of the vehicle air brake, resulting in the inability to automatically find the accidental braking vehicle in real time during vehicle operation and alleviate the failure. Vehicles and train accidents induce emergency vehicles. For vehicles with the above problems, after the vehicle brake valve is removed, the pressure changes at key points of the vehicle's air brake during braking and release are tested in the laboratory to determine whether the vehicle has corresponding problems. However, it is impossible to monitor the vehicles in operation in real time, so that there are certain safety hazards in the operation of v...
