I. case overview

With the development of economy, China's sewage discharge has been more and more large, has caused serious pollution of surface water, environmental quality shows a deteriorating trend. The traditional water quality data collection cannot obtain the accurate information of water pollution in the first time. The water quality monitoring methods used in the past are far from meeting the needs of environmental protection.

A large-scale horticultural exposition needs strict requirements on water quality, and requires high real-time monitoring, low cost, good stability, effective unified supervision of the region, and timely online monitoring and alarm.

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 demand, host of expo, using wireless remote acquisition and control technology, collocation of MT - SR411 intelligent measurement and control terminals, has developed for its collection nine parameter data acquisition, automatic control and transfinite alarm function for the integration of water quality on-line monitoring cloud platform system. This product helps the horticulture fair to realize the online monitoring of water quality and timely alarm, helping the fair to be held smoothly.

Ⅲ.System functions

Remote collection and monitoring: monitoring center software and mobile APP synchronize monitoring data, which is convenient for managers to check the site situation and equipment status at any time and anywhere, and remote program control pump, which is convenient for timely detection and treatment of problems.

Remote control: remote control of the submersible pump on and off, for water intake analysis.

Real-time monitoring: real-time monitoring of water quality changes, including permanganate, total phosphorus, total nitrogen, ammonia nitrogen, PH, dissolved oxygen, conductivity, turbidity, temperature and a total of nine parameters.

Real-time alarm: water quality alarm can be given after water quality exceeds the limit. Alarm methods include: software alarm and SMS alarm two kinds; Software alarm to alarm by sending alarm sound, SMS alarm to send alarm message to the relevant responsible person.

GIS function: GIS map can visually display the distribution of each water quality monitoring point and the water quality data monitored by the monitoring point.

Historical data query: the function of generating curve of historical data query is realized. By setting the time of year, month and day to generate curve, it is convenient for staff to conduct intuitive data analysis.

Historical data recording: to realize the statistical function of historical data, historical data can be generated by setting the time of year, month and day and imported into Excel.

Permission management: multi-user multi-permission distribution can be realized according to users, such as: super administrator, administrator, operator, monitor, headquarters monitor.
