RIASSUNTO
The Zigbee network isssued in this paper is used to monitor the enviroment parameters of acquiculture water. Each sensor node of the network, which is composed of various sensors and a Zigbee chip CC2430, could measure temperature, velocity of flow, pH value, content of ammoniacal nitrogen etc. A GPRS module is used to complete data exchanging between remote monitoring center and the wireless sensor network. This system is an application in acquiculture field. Through an algorithm based on neural BP network and D-S Evidence Theory, this system could diagnose the type of water enviroment parameter abnormity automatically.
