In view of the technical problems about power dissipation
miss rate and localization accuracy of existing mine personnel localization system
starting from the system architecture of wireless sensor network based on ZigBee communication technology
the key techniques of sensor terminal design
localization mechanism and wireless network topology were in-depth researched.In this paper
engineering realization of the sensor node design
localization algorithm and wireless networking technology were given
optimization of technology or improvement of strategies was proposed in each unit module.They can improve the comprehensive performance of the existing wireless sensor localization system.
