Abstract


In the coal mine safety monitoring system, as detected by the sensor is directly related to coal mine safety monitoring system reliability and sensitivity of the monitoring and control plays a decisive role . To ensure the mine gas sensor measurement accuracy , the sensor must be carried out according to certain requirements for periodic testing . The use of mine gas sensor calibration system test mine gas sensors, able to fully assess the measurement of mine gas sensor performance, making coal mine safety monitoring system to effectively play the role of monitoring and control . In this context, the development of mine gas sensor test system, which by the mine gas sensor calibration device and the host PC components. This topic in the study mine gas sensor test based on the principle , design verification device mine gas sensor gas loop control circuit based on microcontroller AT89S52 with host PC communication circuit and frequency measurement circuit . Where the frequency measurement is the core of the entire test system , widely used in the middle of this focus on the band measurement and other precision frequency measurement method, design and development and other precision frequency measurement hardware circuitry and software , so that the verification system throughout its test frequency range to achieve precision frequency measurement . In order to measure the frequency of remote data transmission and verification device on the host PC control using RS-485 communication protocol, developed a host PC and serial communication software verification device . Via serial communication software to the test showed that the PC interface , and the use of a PC powerful data processing capability of saving data to facilitate a more intuitive understanding of the staff certification status , the implementation of appropriate treatment and control. At present, the development of the mine gas sensor test system has been running laboratory testing and field trial results show that its simple operation, good stability, easy to maintain. The system data processing capability, test accuracy, anti-interference ability for mine gas sensor automatic verification provides a practical solution.
