Wheel detection device with double sets of axle counters and its calculation method for axle counting

Abstract

The invention relates to a wheel detection device with double sets of axle counters and an axle counting calculation method. Two sets of axle counters are provided, and each set of axle counters is provided with two axle counting sensors. The sets of axle counters are respectively arranged at both ends of the track control area, and the two axle counting sensors of each set of axle counters are respectively fixedly installed in the inner rail waist or outer rail waist of the two rails at the location, and communicate with a controller. Control connections. Axle counting calculation method: by separately counting and comparing the four axle counting sensors of two sets of axle counting devices to determine the vehicle stay and entry and exit conditions in the control area. In order to clear; to ensure the accuracy of the counting shaft when individual sensors fail, and to improve the safety factor. The invention is suitable for the safety control of rail traffic, and has the advantages of simple structure, low cost, easy maintenance, accurate detection and stable performance.

Description

Technical field [0001] The invention belongs to a detection and control device for rail transit vehicles. Specifically, the axle counting sensor installed on the steel rail is used to calculate the number of axles entering and leaving the control area, so as to accurately control the safe passage of the vehicle and ensure the safety of driving. Background technique [0002] With the rapid development of rail transit and the improvement of automation control, the requirements for the management quality and strictness of vehicle operation are also getting higher and higher. Especially in some key control areas, it is necessary to precisely control and record the driving in and out of vehicles to ensure safe driving. In this work, the wheel detection device is a commonly used equipment. At present, in the axle counting system of the existing detection device, only one set of axle counting sensor is installed at each axle counting point. When a certain sensor fails, the measured res...

AI Technical Summary

Problems solved by technology

At present, in the axle counting system of the existing detection device, only one set of axle counting sensors is installed at each axle counting point. When a certain sensor fails, the measured results will be inaccurate, and the track section controlled by it will be inaccurate. Unable to accurately judge the entry and exit of vehicles, resulting in traffic interruption and even dangerous accidents
