Abstract

The invention provides an emergency communication command, positioning and sensing system. The system comprises communication base stations, wireless communication terminals, wireless sensors, positioning tags and a server. The communication base stations and the wireless sensors provide wireless grid network networking and signal coverage for the system. A broad-band wireless local area network is formed among the communication base stations and broad-band wireless access is provided. A narrowband sensing network is formed among the wireless sensors and narrow-band wireless access is provided. IPV6/6Lowpan protocol networking is used between the communication base stations and the wireless sensors. The server is connected with any one communication base station. Each wireless communication terminal accesses the communication base stations through the broad-band wireless local area network. Each positioning tag communicates with the communication base stations or the wireless sensors through the narrowband sensing network. The server issues monitoring information to the wireless sensors and the positioning tags through the communication base stations. By using the emergency communication command, positioning and sensing system provided in the invention, a narrow-band low-power-consumption advantage and a broad-band wireless communication capability of a sensing network are possessed simultaneously.
