Problems solved by technology

If one set is idle due to interference and other factors, when the other set is occupied, it uses the idle result. Under this architecture, if a sensor loses the axle, the consequence may cause a serious safety hazard of the axle counting system losing the vehicle.

Embodiment Construction

[0022] Attached below figure 1 The redundant fault-tolerant axle counting processing device and its processing method of the present invention are described in detail.

[0023] A redundant fault-tolerant axle counting processing device, characterized in that: the processing device includes a wheel detection assembly, an axle counting assembly, and a section processing assembly; the wheel detection assembly includes sensors arranged at axle counting points on track sections, each The number of sensors on the axle counting point is two, which are respectively arranged on the two rails of the track; the axle counting assembly is used to process the wheel axle signals detected by the sensors and convert them into digital signals of the number of wheel axles; the area The segment processing component is used for processing the digital signal and comparing and judging whether the track segment is occupied or idle. The section information of the adjacent track sections is exchanged ...

Abstract

The invention relates to a redundant fault-tolerant axle counting processing device and a using method thereof. The processing device comprises a wheel detection component, an axle counting component and a sector processing component, wherein the wheel detection component comprises sensors arranged at the axle counting points on a track sector, two sensors are arranged at each axle counting point and arranged on two rails of a track, the axle counting component is used for processing wheel axle signals of wheels sensed by the sensors and converting the signals into digital signals about the number of wheel axles, and the sector processing component is used for processing the digital signals and judging whether the track sector is occupied or idle. The device has the advantages of being simple in structure, reasonable in design, safe, stable and reliable in operation, capable of being applied to complicated environments including subways and tramcars, and the like. By the adoption of the method, risks possibly caused by single-point axle missing and multiple axles are avoided, and unavailability caused by mistaken occupation due to single-point axle missing and multiple axles is avoided.

Description

technical field [0001] The invention relates to the technical field of railway axle counting systems, in particular to a redundant fault-tolerant axle counting processing device and a processing method thereof. Background technique [0002] In the process of railway traffic command, operation, and dispatching operations, in order to check the state of rail lines occupied by trains, track circuits are often used to check the vacancy and occupancy of track sections or turnout sections as the basic unit of railway signaling systems. However, the above-mentioned track circuits are used There are disadvantages such as easy short circuit, difficult construction, high failure rate and high maintenance cost. [0003] In recent years, the axle counting system has emerged. The axle counting system interprets the signal in the axle counting sensor as the number of driving axles, and transmits it to the host computer in the control room for calculation and processing, and calculates the...
