I. Overview

The water cycle on the earth mainly includes two forms, natural cycle and artificial cycle. The natural cycle process is: seawater evaporation -> rainfall -> rainwater drainage -> entering the sea; the man-made cycle process is: seawater evaporation -> rainfall -> water intake from water sources -> water purification -> water delivery -> water use -> sewage drainage -> Sewage treatment -> entering the sea. In China, after decades of development, the infrastructure and application experience in water intake, water purification, water delivery, water use, and sewage treatment in the two major cycle processes have been relatively rich, and they can basically deal with extreme emergencies. At the drainage level, the ability to deal with extreme situations needs to be strengthened, mainly including two common drainage problems.

1. Poor drainage. In recent years, many places have experienced floods that have not been seen in decades. Poor drainage in urban areas has led to water intrusion into houses, submerged cars, and endangering the safety of pedestrians in most cities. In addition, black and smelly water bodies in urban areas caused by poor drainage and imperfect drainage engineering construction are also everywhere in the city.

2. Drainage transition, all rainfall is drained away. When there is no rainfall for several months, drought is serious, affecting the normal operation of the city.

In order to solve the above problems, the country has formulated a series of related policies for sponge cities and black and smelly water bodies. Implementation plans include: sponge city construction, treatment of black and odorous water bodies, dredging of drainage pipe networks, rainwater and sewage combined and diversion measures, elimination of industrial direct discharge and illegal discharge, treatment of misconnected and misplaced pipe networks, and re-optimization of drainage and water storage projects according to the drainage needs of urban development. facility. Through the implementation of the above plans, we can ensure the normal operation of cities and new rural areas, completely solve the problem of major rains, floods and droughts, or reduce the occurrence of such events and reduce the degree of losses. In the process of discovering drainage problems, formulating drainage project construction requirements and evaluating the optimization effect of drainage facilities, monitoring of drainage flow, water level and related parameters is an indispensable and important link.

2. Equipment functions

The drainage pipe network flow monitoring system is responsible for monitoring the flow, flow rate, water level, and water temperature during the drainage process. It can be customized to monitor water quality pH, conductivity, turbidity and other parameters.

The drainage pipe network flow monitoring system consists of the following main parts:

1. Flow velocity flow measurement sensor: usually an ultrasonic Doppler flow velocity flowmeter;

2. Pipe network host: its function is to provide long-term power supply and implement power management for sensors to achieve low power

Consumption, built-in DTU realizes data conversion and transmission from industrial bus to Ethernet.

3. Cloud platform: Provides project site management, receives monitoring data, stores display and downloads.

4. Installation accessories: special bracket for flow meter installation, pipe network host installation bracket, flow card, supporting debugging tools, etc.
