Problems solved by technology

The planned water distribution method is easy to operate and quick to operate, but its management is extensive and the operating cost remains high. With the deterioration of the water quality of the water distribution source, its water quality guarantee function is becoming more and more difficult to realize. Therefore, there is an urgent need for a smart water distribution system for rivers. The system solves the above problems

Embodiment 1

[0028] A city river water distribution project, the river has a total length of 4km, an average width of 15m, and an average depth of 2m. The existing water distribution facilities have a water distribution capacity of 20,000m 3 / d, the source of water distribution comes from the upper reaches of the river; as the upstream water quality tends to deteriorate, the purification effect of water distribution on the river is getting worse and worse, so the water distribution system of the river is intelligently transformed and constructed. 15,000 m were allocated for renovation and construction 3 / d's ceramic membrane filtration device, hydrological water quality online monitor, PLC control system, data transmission module and intelligent water distribution control platform. The online monitoring system monitors parameters such as pH, turbidity, and dissolved oxygen in the river, and transmits the data to the PLC controller. The PLC controller transmits the monitoring data to the se...

Embodiment 2

[0030] For a river water distribution project in a certain city, the river has a total length of 1.8km, an average width of 12m, and an average depth of 1.5m. The transparency of the original river water body is about 0.3m. In order to improve the water quality, a new intelligent water distribution and purification system has been built, which is equipped with 5,000 m 3 / d's sand filter device, hydrological water quality online monitor, PLC control system, data transmission module and intelligent water distribution control platform.

[0031] The intelligent water distribution and purification system monitors the pH, turbidity, dissolved oxygen and other parameters in the river online, and transmits the data to the PLC controller. The PLC controller transmits the monitoring data to the server equipped with the intelligent water distribution control platform through the wireless transmission module. The intelligent water distribution control platform analyzes and judges the moni...

Abstract

The invention relates to an intelligent riverway water distribution method and system. The intelligent riverway water distribution method and system aim to effectively guarantee water quality of rivers in cities. According to the technical scheme, the intelligent riverway water distribution method comprises the following steps that (1) a hydrology-water quality online monitoring device and a water distribution purification device are mounted; (2) the hydrology-water quality online monitoring device and the water distribution purification device are connected with a PLC; (3) the PLC sends received data to a server; (4) an intelligent water distribution control platform makes a judgment according to hydrology-water quality monitoring results; (5) the PLC controls the water distribution purification device according to control signals. The intelligent riverway water distribution system comprises the hydrology-water quality online monitoring device, the water distribution purification device, the PLC, a data transmission module and the server. The hydrology-water quality online monitoring device and the water distribution purification device are connected with the PLC respectively, and the PLC is connected with the server.

Description

technical field [0001] The invention relates to the fields of ecological management and environmental protection engineering, in particular to a river intelligent water distribution method and a river intelligent water distribution system. Background technique [0002] With economic development, China's urbanization process is accelerating. Along with urban expansion and population growth, many environmental problems have also arisen, such as the pollution of urban inland rivers. Taking Hangzhou as an example, there are 470 (segments) of rivers in the Hangzhou Ring Expressway, with a total length of 1,000 kilometers and a water surface area of ​​26 square kilometers. About 50% of the rivers in the urban area of ​​Hangzhou are inferior to Class V. Due to the poor self-purification ability of urban inland rivers, the main All rivers rely on water distribution to maintain water quality. Relevant statistics show that six water distribution pump stations have been set up in a ce...
