Sewage monitoring network structure based on wireless sensor network

The invention discloses a sewage monitoring network structure based on a wireless sensor network, comprising a monitoring center, a plurality of sewage parameter monitoring systems and a sewage treatment process monitoring system, wherein the sewage parameter monitoring systems are connected with the monitoring center by the wireless sensor network and is based on a ZigBee network; each sewage parameter monitoring system and the sewage treatment process monitoring system respectively comprise a communication module, a base station and sensor nodes; the communication module communicates with the wireless sensor network; the base station communicates with the communication module; the sensor nodes are connected with the base station; the base station is used for receiving and fusing data transmitted from the sensor nodes and outputting the data to the communication module; and the sensor nodes are used for monitoring parameters of sewage or the sewage treatment process, and transmittingthe monitored data to the base station by the ZigBee network; and each sensor node comprises a ZigBee module. In the sewage monitoring network structure, by utilizing a wireless sensor technology, the environmental accidents can be found in time, the occurrence and the development of the accidents can be monitored and estimated and then emergency strategies and measures can be made.
