ZigBee wireless Ad Hoc network system and method for monitoring security of dam

Abstract

The invention discloses a ZigBee wireless Ad Hoc network system and a method for monitoring security of a dam, and belongs to the field of security monitoring and structural health diagnosis of water conservancy projects. The system consists of a data acquisition layer, a data transmission layer and a monitoring centre, mainly comprises a dam acquisition sensor, an information acquisition node, a routing node and a coordinator node of ZigBee network, a wireless transmission structure and a remote security monitoring centre. In the method, the remote security monitoring centre issues various operation instructions to the field ZigBee node of the dam and receives information from the field wireless node; the field ZigBee node mainly acquires and wirelessly transmits the dam information, connects neighboring nodes to realize networking function and responds to the control instruction sent by the monitoring centre. By changing the conventional wired security monitoring technology and structural health diagnosis technology of wiring, the invention has the characteristics of low cost, low power consumption, modularization design, high level of integration and strong function expandability.

Description
