Mine locomotive running state detection method adopting railway vehicle axle counter

Abstract

The invention relates to a method for detecting mine locomotive running state, which adopts a railway vehicle axle counter. The device consists of a computer (4), a communicator (1), a control substation (2), the railway vehicle axle counter (3) and a signal machine (5). In the system, the technology is implemented by two ways: (1) embedded program way is used for realizing track locomotive axle counting detection algorithm; and (2) an axle counting interface circuit is based on the detection method. The axle counting detection algorithm is implemented in the control substation, formed by five parts which are a signal sampling and processing process, a direction processing process, an axle counting statistical process, a vehicle speed judging process and a vehicle locating process; RS232 bus communication is adopted between the computer and the communicator, FSK bus communication is adopted between the communicator and the control substation, and a two-wire current-mode interface is arranged between the control substation and the railway vehicle axle counter. The invention can be used for detecting and processing the dynamic-state operation process of atrack locomotive, and realizes the functions of direction judgment, speed measurement and calculation, data statistics and locomotive location.

Description

technical field [0001] The invention relates to multiple technical fields such as computer control technology, field bus communication technology, embedded system development technology, mine explosion-proof design technology, etc., and is mainly applied to the detection of the running state of rail locomotives in various mines. Background technique [0002] At present, the rail locomotive transportation system is still the main form of mine transportation. When performing signal block control, accurate locomotive positioning is usually the premise. At present, locomotive positioning sensors and locomotive positioning detection methods have more or less technical problems, which cannot fully meet the needs of rail transportation monitoring. For example: one is to use wiring or proximity switches for signal acquisition. There are many and cannot identify the driving direction, the number of wagons and the speed; the second is the infrared receiving method, which has poor anti...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the hidden safety problem of locomotive positioning detection technology in the above mine rail transportation, the present invention provides a mine locomotive running state detection technology using rail axle counters. This technology uses rail axle counters as the core sensor for locomotive positioning. It can not only judge the locomotive position, but also detect information such as vehicle speed, running direction, number of wagons, etc., making the interlocking calculation of system-level transportation dispatching signals more rigorous and reliable
