Embodiment 1

[0021] See figure 1 ,

[0022] The invention is divided into a signal collection part, a crossing part, a signal transmission and sending part, and a mining area crossing monitoring center part.

[0023] The signal acquisition part is mainly used to collect train approaching and leaving signals, and provide decision-making signals for automatically retracting and retracting guardrails. At present, there are vibration sensors, radio frequency sensors, GPS+ARM+GPRS, video monitoring equipment or pedal switches in the crossing system to detect incoming vehicle signals, each of which has its own advantages and disadvantages. The signal acquisition part of this system is composed of 4 magnetoelectric sensors, which are respectively placed in pairs on the inner side of the railway crossing rails in the mining area on both sides of the crossing. When a train passes by the device, the magnetoelectric sensor can detect the incoming train signal, and after passing through the amplifie...

Abstract

The invention discloses a mine railway crossing monitoring system based on GPRS (general packet radio service) communication. The mine railway crossing monitoring system based on the GPRS communication mainly consists of at least one group of magnetic-electric sensors, a signal processing circuit, a single chip computer, a GPRS double-frequency module and a main control mechanism, wherein two magnetic-electric sensors form one group of the magnetic-electric sensors and are symmetrically and respectively arranged on the inner side of each steel rail at the crossing of a mine railway by utilizing the axial line of the mine railway as an axis of symmetry. The signal processing circuit, the single chip computer, the GPRS double-frequency module and the main control mechanism are connected with the magnetic-electric sensors in sequence. The mine railway crossing monitoring system based on the GPRS communication has the advantage of realizing the automation and the informatization of the safety management of the railway crossing.

Description

technical field [0001] The invention relates to railway monitoring, in particular to a mine area railway crossing monitoring system based on GPRS communication. Background technique [0002] The railway in the mining area is the intermediate link connecting the national railway and the mining area, and is an important part of the railway transportation network. According to relevant statistics, at present, there are more than 20,000 kilometers of railways in domestic mining areas, and there are usually many crossings along the lines. Because most of the crossings are distributed in mining enterprises far away from the urban area, and the number and dispersion of crossings are long, and the crossing operations of various transportation tools in the mining area and the unfixed flow of vehicles and personnel make the mining area The safety management of railway crossings has become a very prominent problem. Therefore all levels of mining area management departments cannot tim...
