Sewage treatment monitoring system based on internet of things

Abstract

The invention provides a sewage treatment monitoring system based on an internet of things. The sewage treatment monitoring system based on the internet of things is simple in structure, low in cost and easy to install and maintain, and comprises a water quality sensor, field control equipment, a heterogeneous data receiver, a PLC / DCS controller, an ad-hoc network wireless node, a wired / wireless redundancy ring network, an operator station, a chart printer, an industrial Ethernet, an NOM server and a mobile client terminal. The sewage treatment monitoring system based on the internet of things can be compatible with multi-network protocol conversion, monitors various water quality sensors and control devices in real time through a wired / wires redundancy ring network node, performs analysis, early warning and precise control on the phenomena of equipment failures, excessive energy consumption, abnormal water quality and the like through cloud computing and large-data mining, and avoids equipment failures, water discharge beyond standards and the other major accidents. The sewage treatment monitoring system based on the internet of things is simple in network construction, low in cost and easy to install and maintain, and has good application prospects.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a sewage treatment monitoring system based on the Internet of Things Background technique [0002] The topic of water pollution is constantly being brought up, especially the problem of groundwater pollution. Farmers or entrepreneurs in Zhejiang Hangzhou, Wenzhou and other places have paid for the director of the Environmental Protection Bureau to swim in the river to arouse everyone's attention to the severity of water pollution. Although various environmental protection The bureau chief chose to remain silent or refuse, but the public's awareness of environmental protection has awakened, and their concern about water pollution has reached an unprecedented level. The increasing water pollution has brought unprecedented attention to the sewage treatment and recycling industry. In the past two years, the gross profit margin in various regions has remained at around 70%, and some region...

Problems solved by technology

In the application process of the existing technology, the PLC site and the sensor are arranged far away, and the sensor generally uses 4-20mA signal transmission and is connected through a special signal shielding cable, which brings difficulties in construction and maintenance; there are many types of wired network transmission methods and protocols. Such as RS485, DH+, TCP / IP, etc., often have the problem of incompatibility between interfaces of multiple manufacturers during the implementation process, which is also not conducive to further upgrading and expansion of the system; while the central control room is only responsible for data display and control, and has not achieved Intelligent level, unable to realize fault warning and forecast
