Research of Initiative Personnel Orientation and Rescue System in Mine based on Synchronous Signal Sensei Technology
According to shortcomings of short-distance signal recognition, low signal transmission reliability, high rate of leakage reading and single function that exist in current underground personnel orientation system, a new system based on Synchronous Signal Sensei with initiative RFID technology has been designed. The systems hardware and software is detailed designed including its working principle. The initiative communication process is realized by the SoC chip of nRF9E5. An emergency alarm circuit is added to the identification card. Based on the analysis of characteristics of underground wireless communication, a deep research was done to synchronous signal sensei technology and its realization process in order to reduce power consumption. Signal transmission mechanism is improved to return the correct confirm signal for once a time. The test results show that the communication distance between the card and the wireless location substation can reach 80m with 10 dBm of transmission power and 433.6MHz of communication frequency.
