Collector shoe arc discharge early warning intelligent measurement and control device, and subway vehicle and control method thereof

Abstract

The invention discloses a collector shoe arc discharge early warning intelligent measurement and control device, and a subway vehicle and a control method thereof. The collector shoe arc discharge early warning intelligent measurement and control device comprises a main control computer, a temperature sensor, a humidity sensor, a speed sensor and an image collector. The temperature sensor is electrically connected with the main control computer and is used for detecting the air temperature outside a subway vehicle; the humidity sensor is electrically connected with the main control computer and is used for detecting the air humidity outside the subway vehicle; the speed sensor is electrically connected with the main control computer and is used for detecting the speed of the subway vehicle; and the image collector is in communication connection with the main control computer and is used for collecting images of a collector shoe and a contact rail of a subway vehicle, and the main control computer is further in communication connection with the vehicle-mounted microcomputer of the subway vehicle and is used for obtaining the voltage and the current of the collector shoe. The phenomenon of arc discharge of the collector shoe is reduced or avoided, so that the driving safety and reliability of the subway vehicle are improved.

Description

Technical field [0001] The invention relates to the technical field of subway vehicles, in particular to an intelligent measurement and control device for early warning of arcing of a collector shoe, a subway vehicle and a control method thereof. Background technique [0002] At present, subway vehicles are a common means of transportation for people's daily travel. The power supply methods of subway vehicles are divided into two types: catenary power supply and contact rail power supply. Metro vehicles using contact rail power supply are more widely used. When the subway vehicle uses contact rails for power supply, there will be discontinuities at the railway turnouts when the contact rails are laid. After long-term operation of subway vehicles, the gap between the collector shoe and the contact rail will increase due to vehicle vibration and wear. And when the subway vehicle passes through the critical area of ​​the discontinuous area of ​​the contact rail. At this time, if t...

AI Technical Summary

Problems solved by technology

At this time, if the vehicle speed is fast, the air humidity is high, and the gap between the collector shoe and the contact rail of the subway vehicle is large, it is easy to cause arcing between the collector shoe and the contact rail, and then the collector shoe and contact rail The contact rail is burned, which leads to the reduction of the operation reliability of the subway vehicle and the large economic loss
