Ⅰ.Summary of case

In recent years, some enterprises do not treat sewage, direct discharge to all levels of river, resulting in serious water pollution, water environment deterioration in most areas of the water quality of the water shortage. For governments at all levels and the departments of water administration increased the water management and water conservation, water conservation planning and forecasting of water environmental capacity and pollution reduction, the implementation of water pollution total amount control, need for online monitoring of river water quality, monitoring data including pH, total phosphorus, dissolved oxygen, conductivity, turbidity, UV - seven parameters of COD, ammonia nitrogen, which can evaluate the river water quality, determine if it is polluted, and the nature and degree of pollution, so as to take effective measures in a timely manner

A town in wuxi, as companies and city discharges sewage at random and non standard drainage, causing serious pollution, surface water environment quality present deteriorating trend, but the place of pollution sources and drainage canals of water quality monitoring is still in the stage of manual monitoring, time low coverage, lack of scientific and representative sample, it is difficult to reflect the enterprise and the urban sewage of continuous change. Therefore, the local government is looking for an effective, practical and advanced monitoring system and solution. In order to strengthen environmental monitoring, it is imperative to establish an online monitoring system for wastewater and improve water quality monitoring capability.

Diffuse way science and technology development in the Yangtze river delta region and the wisdom to build capacity in one industrial Internet service providers, according to the requirements of the town, using edge computing technology, the Internet of things collocation Mantoo cloud network connected to the remote measurement and control system control cabinet, for its collection of water quality parameters is developed by automatic data collection, processing, saving and remote communication functions as one of the river water quality monitoring system cloud platform. The system can realize automatic sampling of river water quality and on-line monitoring of main pollution factors. Automatic transmission of monitoring data; Water quality parameters are automatically collected, processed, stored and transmitted by monitoring points, and data are collected, sorted out and comprehensively analyzed in the computer control center of the central station. It not only saves a lot of manpower and material resources, reduces the operation cost, but also shortens the monitoring time and realizes the real-time monitoring of sewage.

Ⅲ.System function

※Data call and test: the normal real-time data is collected according to the set time division. The call and test function can realize the real-time recall of monitoring data, and 4G wireless communication is adopted.

※Real-time data display: local host and remote host, mobile terminal data synchronous real-time display

※GIS map display: visually display the location, name, status and real-time monitoring data of monitoring points

※Abnormal alarm: when the device status and communication are abnormal, or the monitoring data exceeds the limit, the alarm will be given in the form of icon color change flashing and text report

※Data query: can customize the query conditions for historical data, alarm data, login and communication log, operation log query

※Data statistics: conduct statistics, analysis and summary for 

instantaneous data and cumulative data, and generate curves and bar charts

※Report generation: support the generation of daily report, monthly report and annual report for all monitoring data and alarm information and support printout

※System management: various system parameter setting, user authority management, external data interface management.

Ⅴ.Introduction to hardware products

Product introduction:

Mantoo cloud network remote measurement and control system control cabinet through the RS485 interface technology to collect the data of each sensor, through the 4G network directly uploaded diffuse cloud real-time view, once the data limit, on-site equipment failure, the remote control terminal will appear alarm information, remind personnel maintenance.

Sensor selection:

Monitoring instruments, especially on-line health monitoring instruments and equipment should be selected according to the monitoring items. The selection of sensors should be based on the principle of advanced technology, economic and reasonable, reliable and applicable performance, long-term stability and meeting the monitoring requirements.

Ⅶ.The customer evaluation

The online water quality monitoring system provided by mantu technology plays an important role in environmental protection and water quality monitoring in our region. Water quality monitoring in the river is the most worried about the theft of discharge, the impact of an hour of enterprise drainage on the water quality may be three months of substandard, and the system in each sewage point monitoring water quality, and video linkage, when the water quality exceeded the first time trigger alarm, and video evidence, the phenomenon of theft discharge is basically eliminated. Every week, every month and every year, we can also automatically generate environmental reports to help us reproduce the green mountains and green rivers.
