Abstract
The invention relates to an intelligent coal seam gas pressure tester, which can effectively solve the problems of an instrument for testing the pressure and pressure change law of coal seam gas. A pressure sensor is arranged in a pressure testing room of the conventional pressure testing pipe and is used for transmitting a signal to a singlechip through a data line, and the singlechip is analyzed by using a computer, so that the pressure parameter and pressure change law parameter of coal seam gas can be obtained, and measured parameters are safe and reliable. The pressure tester plays an important role in guiding safe production of coal mines. The pressure tester has a simple, novel and unique structure, saves a large amount labor force and time, is an innovation in the coal mine industry, and has large social benefit and economic benefit when being popularized and applied.
Description
Technical field
The present invention relates to the safety of coal mines field, particularly a kind of Intelligent coal seam gas pressure tester.
Background technology
At present, the original gas pressure in test coal seam, colliery, countries in the world is to the coal seam drilling, setting of casing, and the setting pressure table, employment goes the variation of observed pressure table to test the original gas pressure in coal seam.This method of testing can not real time record gas pressure situation of change, and can vary with each individual during test and can cause error, a kind of Intelligent coal seam gas pressure tester of being badly in need of a kind of energy real-time monitored and can recording.
Summary of the invention
For above-mentioned situation, purpose of the present invention is exactly to be to provide a kind of novel tester, and this instrument is that it can realize real-time monitored and record gas pressure and the parameter situation of change such as gas pressure.
The invention reside in its pressure measuring chamber setting pressure sensor in the innermost end of traditional piezometer tube, and the information exchange that sensor is accepted crosses data wire and interface is passed to single-chip microcomputer, single-chip microcomputer is preserved the information of sensor and record.By the time manometric reading decay alarm device is reported to the police, and the technician takes off single-chip microcomputer, puts into computer analysis.Namely know gas permeation speed in gas pressure in coal seam, gas pressure situation of change, coal seam, simultaneously 13 connect the gas flow that flow meter can survey in instrument connection and can calculate the permeability coefficient in coal seam by flow.This instrument has improved the accuracy of coal-bed gas pressure greatly, significant to instructing Safety of Coal Mine Production.Also having reduced simultaneously the safety that testing cost has improved the people, is an innovation greatly of coal mine gas parameter testing, applies and has great social effect and economic implications
