Locomotive positioning communication system

Abstract

The invention relates to a mining locomotive positioning communication system, which comprises underground equipment and ground equipment, and is characterized in that the underground equipment comprises a mining multimedia communication access gateway, a mining locomotive positioning communication substation, an intrinsically safe identification card, an optical fiber and a power supply; the ground equipment comprises a locomotive positioning mainframe, a locomotive positioning software, a network exchange and a power supply; the mining locomotive positioning communication substation reads the identification information of the intrinsically safe identification card through a RFID (radio frequency identification devices) wireless network, and is interconnected with the mining multimedia communication access gateway through the wireless network to transmit the positioning information of the identification card to the network; the locomotive positioning mainframe is connected with the mining multimedia communication access gateway through the network exchange. The mining locomotive positioning communication system of the invention has a simple structure and high positioning accuracy, is convenient to allocate, operate and maintain, and meets the current requirements of underground locomotive positioning, signal light control and locomotive management.

Description

technical field [0001] The invention relates to a mine communication system, in particular to a mine locomotive positioning communication system. Background technique [0002] Coal is an important energy source in my country, accounting for about 70% of primary energy. More than 95% of my country's coal mines are underground mining. Poor coal storage conditions, deep mining depths, gas, coal dust, floods, fires, rock bursts, and geothermal heat have plagued the healthy development of the coal industry. high-risk industries. Analyzing the reasons, there are not only problems such as chaotic management, low quality of personnel, insufficient security investment, weak scientific research, but also backward communication equipment in coal mines. [0003] Coal mine underground is a special working environment. Therefore, the mine communication system is different from the general ground mobile communication system, and has the following characteristics: [0004] (1) Intrinsical...

AI Technical Summary

Problems solved by technology

[0005] (2) Large transmission attenuation

Therefore, the volume of communication equipment cannot be very large

[0007] (4) Low transmit power

[0013] It can be seen that the existing technology applied to the locomotive positioning in coal mines not only fails to fully meet the requirements of high-precision real-time positioning, but also has not simultaneously realized signal light control, real-time uploading of locomotive operating electrical parameters, video monitoring, industrial Ethernet interconnection, etc. Function
