Water pollution degree to the traditional artificial detection efficiency is low, the problem of real-time monitoring capability is not strong, was designed and implemented based on web network to optimize the protocol of real-time online water quality pollution level automatic monitoring system, the system USES wireless sensor network node of regional water quality monitoring, via a wireless packet communication technology and broadband network for remote data transmission, the staff can realize real-time online web information query, water quality management and control, data collection and alarm prompt operation, water quality monitoring system based on web, improve the system scalability, ease of use, and real-time performance, etc. The system hardware includes sensor module, wireless communication module, MCU peripheral circuit, Ethernet interface module, etc; System software design of the web network optimization protocol, system monitoring platform, the remote parameter setting, driver, etc. Application of this system for pollution monitoring of water quality of Xi'an moat, 20 monitoring sensor node deployment, a monitoring station node, a remote web monitoring master station, respectively in monitoring the water pH value, the total phosphorus concentration TP, chemical oxygen demand (COD), ammonia nitrogen concentration and sampling time two days in a row, the simulation experiments show that this system has realized a 100% success rate of communication, network access speed is between 5 ~ 8 times of traditional network protocol, wireless sensor network and remote monitoring work stable and reliable, and communication rate meets the demand of real-time monitoring, suitable for urban water quality pollution degree of real-time online monitoring.
