Mining intrinsically safe computer remote terminal system

Abstract

The invention relates to a mining intrinsically safe computer remote terminal system, comprising a ground transmitting device, an underground receiving device and an intrinsically safe power supply. The ground transmitting device and the underground receiving device are connected with each other via optical fibers; the intrinsically safe power supply comprises an AC / DC switch module, an uninterruptible power supply module, a first DC / DC conversion module and a second DC / DC conversion module. The AC / DC switch module is connected with the input ends of the uninterruptible power supply module, the first DC / DC conversion module and the second DC / DC conversion module through circuits; the output end of the uninterruptible power supply module is connected with the ground transmitting device and the underground receiving device through circuits; the first DC / DC conversion module is connected with the ground transmitting device through circuits. The output end of the second DC / DC conversion module is connected with the underground receiving device through circuits. Compared with the prior art, the mining intrinsically safe computer remote terminal system of the invention is safe, reliable, small in volume, light in weight, convenient for carrying and flexible in application by using an intrinsic safety and explosion prevention technology.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to an intrinsically safe computer remote terminal system for mining. Background technique [0002] The safe production of coal mines not only affects the development of society and economy, but also relates to the personal safety of production personnel and social stability; at present, the voice dispatching system and data information transmission system in most coal mining areas in my country use independent channels For transmission, it is necessary to set up a group of independent optical cables or optical fibers separately, and each has an independent interface standard, which is difficult to be compatible; therefore, the information transmission rate of the communication system is low, the efficiency is poor, the reliability is not high, and the transmission cost is high, which not only limits the The development of the coal mining industry has caused many safety hazard...

Problems solved by technology

[0002] The safe production of coal mines not only affects the development of society and economy, but also relates to the personal safety of production personnel and social stability; at present, the voice dispatching system and data information transmission system in most coal mining areas in my country use independent channels For transmission, it is necessary to set up a group of independent optical cables or optical fibers separately, and each has an independent interface standard, which is difficult to be compatible; therefore, the information transmission rate of the communication system is low, the efficiency is poor, the reliability is not high, and the transmission cost is high, which not only limits the The development of the coal mining industry, and there are many safety hazards in the production process

[0003] The modern production of coal mines needs to establish a complete set of management systems based on computers. Therefore, computers are often used in various systems in underground coal mines. However, at the present stage, most of the existing mining computer equipment is installed in explosion-proof boxes. The computer is bulky and heavy, which is not conducive to carrying, maintenance and system update, and is expensive, which is an urgent problem to be solved at this stage
