Research of Overrun Gas-data Wireless Transmission System Based on nRF905

摘要：

According to deficiencies existing in current coal mine monitoring system, this paper puts forward overrun gas-data wireless transmission system developed by STC12C5412AD and nRF905.System hardware structure is expounded. The overrun gas signal detecting is designed, as well as the processing of data launching and receiving. By the experiment, at 915MHz frequency, the systems straight-line communication distance can reach 160 meters in a mine underground transportation roadway. The system has stable data transmission and strong anti-jamming ability.
