Abstract

The invention relates to the technical field of railway locomotives, in particular to a locomotive anti-slip device based on a DSP (Digital Signal Processor). The device comprises a DSP, a wheel rotating speed sensor, a speed measuring radar and a sand scattering valve; and the wheel rotating speed sensor, the speed measuring radar and the sand scattering valve are electrically connected with the DSP. The DSP collects signals of the wheel rotating speed sensor and the speed measuring radar, and controls the opening and closing of the sand scattering valve after corresponding processing. The problem that existing manual sand scattering operation time is long can be solved, the labor intensity of a driver is reduced, and automatic, real-time and efficient monitoring and anti-slip are achieved.

Description

technical field [0001] The invention relates to the technical field of railway locomotives, in particular to a DSP-based locomotive anti-idling device. Background technique [0002] When the train is running on high slopes and curves, when it encounters rain, snow, frost, fog and the track surface is not clean, there will be idling in which the moving wheel of the locomotive rotates rapidly and the train does not move forward because the traction force of the moving wheel is greater than the adhesion force Phenomenon. The rotation speed of the moving wheel rises rapidly during idling. If left unchecked, it may exceed the construction speed for a few seconds or a long time. This will not only reduce the traction of the vehicle, but also cause serious scratches on the tread of the wheel set due to high-speed idling. At the same time, the rotor winding of the traction motor may also fly away and "sweep the bore" due to excessive centrifugal force, causing major accidents, so i...
