Embodiment 3

[0073] Embodiment 3: A method for detecting section status in a station by using gravity-inductive axle counting equipment in the station

[0074] A method for detecting the state of a section in a station using gravity-inductive axle counting equipment in a station. The method is to install a sensor unit composed of 3 to 7 gravity-inductive sensors on the rail at each axle counting point of the line to sense the gravity of the rail itself under the wheel gravity. The elastic stress changes under the load, and the wheel signal corresponding to the elastic stress change is generated. The wheel signal is transmitted to the signal processing unit of the wheel electronic detector for processing, and then converted into a pulse waveform, which is then transmitted to the Axle counting CPU unit; the axle counting CPU unit of the wheel electronic detector collects and counts the pulse waveform, compares the data information and calculates the train running information, and then sends t...

Abstract

The invention discloses a gravity inductive type axis-counting device and a method for detecting the state of a tract district thereof, relating to a railway transport management device and a management method thereof. The gravity inductive type axis-counting device comprises an axis detector, an axis-counting information processing system, an input-output subsystem and a power supply, wherein the axis detector is composed of a wheel electronic detector and a gravity inductive type sensor unit; the wheel electronic detector consists of an axis-counting CPU unit, a signal processing unit, a sensor power unit and a state detecting unit; the axis-counting information processing unit comprises a CPU unit, a communication unit, and an I/O unit; and the input-output subsystem consists of a dynamic drive assembly unit, a relay and a button. In the method, a wheel signal is detected by a gravity inductive type sensor arranged on a rail, and is transmitted to the wheel electronic detector and the axis-counting information processing unit for processing, thus judging the state of the tract district. The invention has the advantages of accurate detection result, high reliability, scientific method and capability of realizing automatic judgment on the idle and occupied states of the tract district.

Description

Technical field: [0001] The invention relates to a railway traffic management device and a management method thereof, in particular to a gravity-inductive axle counting device and a method for using it to detect the state of a track section. Background technique: [0002] The detection of the state of the track section is to detect each section of the track, so as to judge whether each section is in an occupied state or in an idle state. At present, the commonly used equipment for detecting the state of the track section is the track circuit. However, because the track circuit uses steel rails as the circuit channel, the insulation performance is not good, and the insulation performance of the line is very high. It is greatly affected by external interference, the condition of the ballast bed and the steel rail. When detecting the status of track sections, there are problems such as poor branching and "red light bands", which lead to misjudgment. There is no section track d...
