Mine monitoring system detection , mine water sump water level downhole important safety parameters , therefore , the real-time monitoring of water storage level in preventing floods accident occurred , and is of great significance in disaster prevention and reduction . Mining inputs water level sensor is developed for the detection of coal mine water storage water level , it can be continuous level signal converted into standard frequency signal transmission to the host computer , and has a real-time display level value , overrun sound and light alarm , the frequency of the signal output and other functions. Need to set the underground water level sensor suitable for stationary use . In the analysis of the current market based on the existing water level sensor , the mine water level sensor design requirements of general technical conditions proposed overall design , and the theoretical basis of the system , method , hardware and software design to do a detailed discussion . Select the differential pressure sensing element, a one-chip microcomputer . AT89S52 as a central processing unit , by the signal amplifying circuit , A / D conversion , the digital display circuitry , sound and light alarm units of the circuit , the signal output circuit and the like . The software is designed with modular programming , software program written in C language . The main subroutines : the main program , the data acquisition subroutine , the subroutine of the data processing , the signal output subroutine , infrared remote subroutine . Effective anti-jamming measures were taken in the design of the hardware and software . Proof: The system has high reliability , strong function , there are broad prospects for the development and application of test and tested .
