Abstract

The invention discloses an intelligent mine pressure monitoring substation and a calibration method thereof. The intelligent mine pressure monitoring substation is composed of a singlechip microcomputer, a communication module RSM3485, an AD (Analog to Digital) conversion module, a liquid crystal module, an operation amplifier, a resistance bridge type stress sensor, a wireless data transmission module and an intelligent data collector, wherein the wireless data transmission module is a highly integrated half-duplex micropower module with ultralow power consumption and is embedded into a circuit between the singlechip microcomputer and the communication module RSM3485. According to the invention, an automatic calibration function is fulfilled through a software-simulation potentionmeter, and the precision is high up to more than grade 0.5.When the intelligent mine pressure monitoring substation is used, a miner light is prevented from being used for awakening, and the collection can be completed automatically as long as a worker walks through a side place about 10-15 meters away by taking a collector.

Description

technical field [0001] The invention relates to a mine pressure monitoring substation. Background technique [0002] At present, in coal mining, the roof pressure must be monitored for production safety. There are multiple mine pressure monitoring sub-stations (or mine pressure monitors) on the market at present, and mine pressure monitoring sub-stations relevant to the present invention are as figure 1 As shown, it is composed of single-chip microcomputer, communication module RSM3485, AD conversion module, liquid crystal module, operational amplifier module, calibration potentiometer and strain bridge pressure sensor. Its shortcomings are: 1. Two potentiometers need to be used for signal calibration. It is very troublesome to adjust the potentiometer bit by bit. Sometimes it takes 10 minutes and can only be adjusted to below level 2; and the potentiometer is mechanical Components will change due to vibration, temperature, and drop, and the long-term stability of the prod...
