Abstract

The invention provides a water level and flow monitoring system and method for an urban drainage pipe network, wherein the system comprises a monitoring terminal which is used for monitoring water area information, a telemetering communication terminal which is in communication connection with the monitoring terminal, a communication unit which is in communication connection with the telemetering communication terminal, a database server which is in communication connection with the communication unit, a system display platform which is in communication connection with the database server, and a power supply equipment which is connected with the telemetering communication terminal. Compared with the prior art, the water level and flow monitoring system and method for the urban drainage pipe network have the advantages of being high in adaptability, high in accuracy, low in time delay, easy to install and capable of achieving automatic early warning.

Description

technical field [0001] The invention relates to the technical field of water body monitoring, in particular to a system and method for monitoring the water level and flow of urban drainage pipe networks. Background technique [0002] Water level and flow monitoring are important monitoring indicators for rivers, rivers, reservoirs and other water bodies, which are of great significance. In the prior art, conventional water level and flow monitoring methods include sensor monitoring, water gauge manual monitoring and Parshall tank measurement. Among them, sensor monitoring can automatically collect analog quantities representing water level and flow, and then convert the analog quantities into water level and flow data through certain circuits and algorithms. [0003] According to the different analog quantities collected, water level and flow sensors can be divided into float sensors, pressure sensors, ultrasonic sensors and other forms. The float type water level gauge is...

AI Technical Summary

Problems solved by technology

The float type water level gauge is relatively cheap and has strong applicability, but when measuring the water level, a separate water level gauge room must be built for it, and the cost of the house even exceeds the cost of the water level sensor

In addition, the pressure sensor is greatly affected by the change of water quality, and needs to be checked and adjusted frequently, which brings difficulties to operation and maintenance; while the ultrasonic water level sensor is above the open channel, there are many external disturbances, and the measured water level often drifts.

On the other hand, the manual monitoring method is time-consuming and labor-intensive. Parshall flume needs to be modified and finalized, which obviously does not meet the site environment of most drainage pipe networks, nor can it meet the requirements of intelligent and automatic water level monitoring.

The water level monitoring method in the prior art has problems such as outdated monitoring means, high monitoring cost, and inaccurate monitoring data, which is not conducive to the further development of water level and flow monitoring work
