Abstract

The invention discloses a sewage treatment engineering monitoring system based on a wireless sensor network. The sewage treatment engineering monitoring system comprises a plurality of wireless monitoring substations, a wireless transmission system and a wireless monitoring master station, wherein the wireless monitoring substations are used for collecting relative information of field apparatuses of the sewage treatment engineering; the data and commands required to be transferred by the monitoring system are communicated through the wireless transmission system; the wireless monitoring master station comprises a monitoring software, a server, a client and an Ethernet switch; and the client and the server exchange data through the Ethernet switch, and the server is mainly used for storing and managing the data of the whole sewage disposal plant. Compared with a traditional PLC (Programmable Logic Controller) control system, the system has stronger data processing capacity and larger system storage volume; and each data collecting module has an independent controller, so that the system has a strong reliability. Compared with the traditional wired transmission systems, the wireless transmission system is utilized, so that the system has the advantages of low cost and convenience for mounting and debugging, etc.

Description

technical field [0001] The invention relates to the technical field of sewage treatment control, in particular to a sewage treatment project monitoring system based on a wireless transmission network. Background technique [0002] With the development of economy and the progress of society, people pay more and more attention to environmental problems, especially water pollution, which has become the most important resource and environmental problem in the world today, and has attracted people's attention day by day. All countries in the world regard water as a precious resource to research, develop, utilize and protect. With the continuous acceleration of urbanization in our country, the discharge of urban sewage is increasing year by year, and industrial wastewater and urban and rural domestic sewage are discharged into rivers, rivers, lakes, seas and soil in large quantities, making the water quality of surface water and groundwater worsening. Seriously restricts economic...
