Mining intrinsic safety type wireless pressure acquiring and transmitting substation

Abstract

The invention relates to a mining intrinsic safety type wireless pressure acquiring and transmitting substation. The mining intrinsic safety type wireless pressure acquiring and transmitting substation comprises a box, wherein the box comprises a front cover and a base, wherein a substation body is fixed in the base; observation and operation buttons are arranged on the front cover; cable guiding-in devices are arranged on two sides of the base; an antenna is arranged on the base; the substation body consists of a mainboard, a BM200N concentrator, an MAS205 exchanger and an OLED module; a WaveMesh protocol is arranged in the BM200N concentration; and the mainboard consists of an MSP microcontroller, a storage module, an RS485 module, an Ethernet-to-serial port module and an ISO modem module. By the WaveMesh communication technology, the mining intrinsic safety type wireless pressure acquiring and transmitting substation can still work normally if part of nodes paralyze in a network, and is suitable for an underground severe environment; a point-to-point route between each two nodes can be established, wireless route equipment under the mine can be reduced, the mining intrinsic safety type wireless pressure acquiring and transmitting substation has the advantages of large specific handling capacity and short data transmission delayed time, and the problem of low acquiring efficiency under the mine can further be solved effectively.

Description

technical field [0001] The invention relates to a pressure acquisition and transmission substation, in particular to a mining intrinsically safe wireless pressure acquisition and transmission substation. Background technique [0002] Coal mining can include several stages of coal mining, fully mechanized caving, tunneling, and back mining. However, the coal mine fully mechanized mining face is the most accident-prone stage in the process of coal mining, and the main impact on safety production is its comprehensive The pressure of the hydraulic support on the mining face; the collection frequency of the mine pressure detection equipment used in coal mine collection in general coal mines is low, but the monitoring equipment cannot collect the instantaneous periodic pressure and impact low pressure when this situation occurs Among them, most of the collection sub-stations mainly sold in the coal mining industry on the market can only collect data from wired sensors; most of the...
