Abstract: Mine sensors play an important role in sensing parameters of coal mine underground environment,and its the stability and accuracy lay the foundation for environmental parameter acquisition. In order to ensure their stability and reliability, a mine sensor's verification system based on C#, ACCESS is proposed, which depends on AQ 6203—2006, AQ 6207—2007 and other relevant national and industry standards of mine sensors. By using multichannel and multi-window to verify gas, temperature, pressure and other mine sensors, besides, this system is also capable of reports printing and managing, which has good stability and high efficiency in real applications.
