| Summary: | This paper proposes a Zigbee network-based real-time indoor personnel location system based on wireless sensor network through research and comparison of existing location solutions and according to the chemical plant personnel location requirements, so as to master the distribution of plant personnel at any time and improve the efficiency of accident rescue at the time of disaster and daily production management, which solves the problems such as complex, high cost and poor real-time performance in the existing location system. The functions of gateway, reference node and blind nodes of the personnel location system were implemented and verified experimentally. The experimental results show that the expected results have been achieved for the nodes in terms of communication distance, ranging precision, low power consumption and small size, meeting the requirements of real-time location tracking of indoor personnel.
