Online monitoring of urban drainage network - guarding urban veins
With the development of the economy, the rise of high-rise buildings in the city, the dense crowds on the streets, and all kinds of restaurants. Office area, residential, carrying people's daily life. And what keeps the city running and balanced is the drainage network hidden underground in the city.
The urban drainage network is like a human vein, and it is necessary to maintain the normal vitality of people's daily life and daily travel. But they also carry a lot of pressure.
For example, the phenomenon of illegal discharge and leakage, unreasonable pipeline design, silt blockage, rain and sewage pipe network mixing and other problems, which will lead to the overflow of the water level of the pipe network and lead to urban waterlogging, affecting the safety of people's daily travel
There are blind spots in monitoring
The underground situation is complex, and the principle of radar flow determines that it is not suitable for the environment of this underground pipe network. The radar flowmeter adopts advanced plane microwave radar technology, which can only monitor the case of non-full pipe, and because of the principle, the radar flowmeter has a certain blind spot, once the water level reaches the blind spot, it will affect its measurement;
In addition, the radar beam angle may hit the inner wall of the underground in the case of narrow space in the pipeline and improper installation, which will affect the measurement accuracy. Severe results that cannot be measured. This is a major pain point of radar, and it is also a difficult point that cannot be overcome at present.
So how to realize the urban pipe network under the full pipe and non-full pipe, and at the same time avoid a series of drawbacks brought by the installation location and method?
The "IP68 telemetry terminal system + SCJ-LL01 Doppler ultrasonic flowmeter of the water meter gives you the answer
Diagram of the pipe network monitoring system
This Doppler ultrasonic flowmeter has an accuracy of 1%, the water level can be measured when the water level is higher than 3cm, and the internal integrated pressure water level meter can be measured with both full and non-full pipes, without blind spots, and is suitable for various types of pipelines. With the telemetry terminal system, it integrates power supply collection and transmission, which can realize the function of real-time data collection and remote transmission, and give early warning according to the water level amplitude, so that the relevant departments can take corresponding measures in time to ensure the safety of people's daily travel.
