In the process of coal mining,the occurrence of coal mine accidents are offten the result of rock stress change in coal mine alley,to solve these problems,reseach was done to improve the power of the transmitting module and the sensitivity of the receiving module.Intermediate-frequency transformer and CX20106A chip designed by SONY company were used to design the circuit.Thus a new design had been implenented,which had low cost,better precision and stability.
