Collector shoe arcing warning intelligent measurement and control device, 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 electric collector shoe arcing, 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 catenary rail power supply. Metro vehicles using catenary rail power supply are more widely used. When the subway vehicle is powered by the contact rail, when the contact rail is laid, there will be a discontinuous area at the railway track switch. After long-term operation of subway vehicles, the gap between the collector shoe and the contact rail will increase due to the vibration and wear of the vehicle. And when the subway vehicle passes through the critical area of ​​the contact rail discontinuity area. At...

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
