Sewage monitoring network structure based on wireless sensor network

Abstract

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.

Description

technical field [0001] The invention relates to a sewage monitoring network structure, in particular to a sewage monitoring network structure based on a wireless sensor network. Background technique [0002] Water environmental monitoring is the basis of environmental protection, and its purpose is to provide scientific decision-making basis for environmental protection. Water environment monitoring is one of the important contents of the supervision of the environmental protection management department. At present, my country implements daily routine monitoring of large rivers, large rivers, coastal watersheds, ports, and bays. For pollution accidents such as red tides, oil spills, and major pollutant leakage, daily Conduct a monitoring. In the event of sudden water pollution accidents such as large rivers, large rivers, and large lakes, existing conventional methods cannot realize rapid, accurate, and dynamic monitoring and forecasting, making it difficult for environmenta...

Problems solved by technology

Due to the difficulty of wiring and the high cost of PSTN, the application range is limited. Although the use of GPRS for data transmission can overcome the shortcomings of wiring difficulties, its network operation and maintenance costs are high, and its network performance is not suitable for the requirements of data transmission networks. The structure and network operation also cannot be managed autonomously and must depend on the mobile phone operator

Furthermore, due to the construction requirements of laying cables and establishing monitoring sub-stations, PSTN and GPRS have the disadvantages of large impact on the original ecological environment, high system investment costs, and limited monitoring water area, and it is impossible to deploy large-scale monitoring sub-stations , Implement multi-point remote real-time monitoring for each small water area

In addition, since the terminal equipment cannot dynamically adjust the sleep mode, the energy consumption of operation is high, and the battery needs to be replaced or charged every short time, which is very inconvenient for remote areas, monitoring areas without power wiring, and large-area monitoring areas.
