Abstract:  Aimed at the defects of current compressed air self-rescue device, such as deep colour which is difficult is be found out in underground, loud noise, poor air purification, unable to solve the communications between surface and underground, we try to optimize and ameliorate the device combined with its original principles in this paper. Based on theoretical analysis, experimental study and CAD software, combined with ZigBee wireless communication protocol, we designed a new and advanced air self-rescue device, which containing LED warning lights, buzzer and high-reflective fluorescent material, achieving the functions of automated warning and starting, and underground communication network in urgency. The basic performance tests of the processed products show that the device parameters are suitable for human adaptability and can be used for underground emergency. The results provide a reasonable solution for workers to rescue themselves in emergency in underground mining.
