Problems solved by technology

[0005] B. The theoretical transmission rate of IEEE802.11b / g single-frequency 2.4G is 54Mbps, the uplink port is only 100M, and the maximum throughput is 20Mbps for one-way transmission and 26Mbps for two-way transmission. With the development of underground communication monitoring technology and the increase of equipment , the amount of data to be transmitted is also rising sharply, and traditional wireless access equipment can no longer meet the needs of modern underground communication
[0006] The intrinsically safe power supply used in the mine has clear requirements on the power consumption of the whole machine and the start-up impulse current (GB3836.4 intrinsically safe explosion-proof standard), and the power consumption of load equipment is generally not allowed to exceed 18W. This requirement limits most common wireless access The use of equipment in the mine

Description

technical field [0001] The invention belongs to the technical field of Ethernet equipment, and in particular relates to an intrinsically safe dual-frequency high-power wireless access equipment. Background technique [0002] Comprehensive automation of coal mines is the guarantee of high yield, high efficiency and safe production in coal mines, and the underground network platform of coal mines is the basis for realizing comprehensive automation of coal mines; at present, many coal mines in my country have established industrial Ethernet for underground coal mining equipment and underground environmental parameters Most of the schemes adopt the underground wired Ethernet method, which is arranged in the main roadway and cannot cover the entire underground; it cannot realize the monitoring of moving electromechanical equipment, such as coal shearers, locomotives, etc.; my country's coal mine comprehensive automation projects have no It can cover the fully mechanized mining face...
