A monitoring and control system for urban drainage network based on big data

Abstract

The invention discloses a big data-based urban drainage network monitoring control system. The big data-based urban drainage network monitoring control system comprises a man-machine interaction module, an alarming module, an external source weather module, a data storage module, a pipe and pump station information base, an analyzing module, a flow sensor, a pump station, a pump station monitoringmodule, a pump station water level monitoring module, an inspection well water level monitoring module and a valve front end. The big data-based urban drainage network monitoring control system can analyze and compute water drainage in an urban drainage network through the analyzing module to adjust the drainage velocity of the pump station in work and reduce the start-stop frequency of the pumpstation, and meanwhile, timely empty a water collecting well through the connected external source weather module to improve the water storage capacity of the drainage network in rain and reduce the possibility of urban flooding; besides, by analyzing the water flow in drainage pipes through the analyzing module, the big data-based urban drainage network monitoring control system can help timely discover damaged or blocked section and implement dredging, maintenance and replacement operation to ensure normal operation of an urban drainage system.

Description

technical field [0001] The invention belongs to the technical field of urban drainage, and in particular relates to a big data-based urban drainage network monitoring and control system. Background technique [0002] Urban drainage system is an important part of urban infrastructure. It not only undertakes the tasks of urban flood control, drainage, and domestic and industrial production sewage discharge, but also is related to urban environment and urban water safety. Urban drainage system mainly includes pipelines and pumping stations. Facilities such as gates, sewage plants, etc., collect domestic sewage, industrial sewage and rainwater in the city, and transport them through pipelines. The pump station pumps the water from the low place to the high place, and transports the sewage to the sewage treatment plant for treatment. [0003] With the construction of the city, the network of drainage pipes is becoming more and more complicated, and the service time of the drainag...

AI Technical Summary

Problems solved by technology

[0003] With the construction of the city, the network of drainage pipes is becoming more and more complicated, and the service time of the drainage pipes is limited. The main reason is that the staff check and repair the drainage line through the inspection well, which will consume a lot of manpower and material resources, and the location of the damaged pipeline cannot be found in time. The urban drainage system needs to be replaced and expanded due to urban construction and aging of the pipeline; due to urban drainage The pipelines in the system cannot be buried deeply, so a pumping station is needed to raise the height of rainwater or sewage, so that the rainwater or sewage can be smoothly discharged to the sewage treatment plant or water body. In the prior art, the pumping station works according to the water level when it is working. When the water level in the collection well where the station is located reaches the preset value, it will start working or shut down. When a large amount of rainwater or sewage is discharged into the collection well, the power of the pump station cannot be controlled according to the real-time displacement. The pump station starts and stops frequently. cause damage to oneself and reduce the effective service life, in order to solve this problem, the present invention provides the following technical solutions
