Design of a Mine-used Wireless Search and Rescue Apparatus

The paper put forward a design scheme of mine-used wireless search and rescue apparatus and introduced circuit design of hardware and realizing flow of software of the apparatus in details. The apparatus uses LPC2136 microcontroller and CC2520 wireless transceiver chip with simple periphery circuits and low power consumption, and can locate position of underground personnel according to information collected by marking card of personnel, which provides an excellent resolution for underground search and rescue.
