Boundary controlling position detector for charged trolley bus in station region

Abstract

The detector set includes left detecting sensor, right detecting sensor, station limit ground sensing source, rising bow ground sensing source and bracket of sensor. The said two sensors through bracket fixed on left end and right end of trolleybus body, and sensed signal through cable is transferred to control system inside trolleybus. The ground-sensing source as a strip shaped passive continuous wider metal piece is buried under roadway at certain place of stop station in advance. Rising bow ground sensing source as a passive metal piece is buried under roadway at station entrance. The detector set determines position of trolleybus within station area so as to prevent strickling line and strickling net from bow trolley and clear hazard.

Description

technical field [0001] The invention relates to a detection device for a trolleybus, in particular to a vehicle position detection and monitoring device for a rechargeable trolleybus in a station area as an urban public transport tool that stops during operation and correctly receives electricity for supplementary charging at a station area. Urban public transport engineering field. Background technique [0002] The rechargeable trolleybus in the station area used for urban public transportation uses large-capacity battery packs or supercapacitor energy storage as the power source for driving the motor, but due to limited energy storage, it still needs to Obtain electric energy intermittently to recharge the on-board battery pack or supercapacitor. The supplementary charging is carried out in the middle of the trolleybus operation line. The special trolley bus catenary for charging in the station area above the district road receives and feeds electricity, so the rechargeab...

Problems solved by technology

[0003] Although the trolleybus is charged in the parking and berth area of ​​the invention, and the trolleybus pantograph is fully automated in its lifting and charging process, but for most of the trolleybus parking stations, the roads in the station area are impossible. There are road shoulders on both sides, and the distance between the road shoulders on both sides needs to meet the requirements of the body width of the rechargeable trolleybus in the station area and the length of the pantograph conductive slide. Therefore, there will be: although the body of the tram The left side or a part of the rear of the car is still outside the boundary line of the traffic sign. The sensor on the trolley bus has received the signal to control the double-wire receiving pantograph on the roof to automatically rise. One of the double wires may still be conducting. In addition to the skateboard, at this time, when the tram stops at the station and continues to move forward, not only can it not be charged by current, but also the conductive skateboard will slide with a large lateral displacement relative to the catenary wire, and the friction resistance of the elastic sliding contact will laterally push the contact suspended in the state of the flexible cable The net wire, the result will affect the stable charging of the previous car in the station area, and may even lead to a scratching accident on the edge of the conductive slide plate that causes the pantograph of the car to elastically float

To sum up, the sensing source and power receiving switch device of this technology cannot give a bow-raising signal according to the correct parking space, and the operation safety of trolleybuses, pantographs, station catenary and other equipment is still subject to the driver's operating regulations, etc. Influenced by human factors, there are hidden dangers of equipment accidents, so the application of this technology still has deficiencies and defects to a certain extent
