Intelligent real-time monitoring and warning system for rainwater situation

Intelligent real-time monitoring and warning system for rainwater situation， In recent years, a large amount of water accumulated at low-lying places of roads, overpasses, tunnels and subway entrances caused by heavy rainfall has occurred from time to time, which has brought a lot of inconvenience to people's travel and life. The river water level and reservoir water level rise sharply caused by rainstorm, and even cause heavy losses of people's lives and property in serious cases. The Implementation Opinions of the General Office on Strengthening Urban Flood Control point out that "establishing and improving the urban perception and collaborative information platform, integrating relevant information on flood control and drainage management from various departments, and deploying necessary intelligent perception terminal devices at key nodes of drainage facilities and flood prone areas to meet the functional needs of daily management, flood control scheduling, emergency rescue, etc.

Monitoring of urban waterlogging and waterloggingEarly warning systems are widely used in meteorology, water conservancy, and urban areasmanagement、Traffic managementRainwater research, reservoirs, hydrologysuperviseApplication and research of measurement stations and other departments.

How to control urban waterlogging has become an urgent need. With years of experience in scientific and technological flood prevention and drainage warning research and development, and the comprehensive use of advanced technologies such as the Internet of Things, cloud computing, big data, and automation control, a set of urban waterlogging perception and coordination systems has been created, which integrates real-time monitoring, automatic uploading, warning release, command and decision-making, and analysis and summary. This has achieved the goal of urban waterlogging preventionUrgent dispatchReal time, visibility, intelligence, and sharingThe goal is to establish a business that runs through the entire process of pre flood, mid flood, and post flood for urban flood prevention and control workSupport system.

The urban waterlogging monitoring and early warning system targets the entire urban flood control and drainage management system, forming real-time monitoring and early warning for multiple flood control and drainage scenarios Sensing of various devices such as rain gauges, water level gauges, electronic water gauges, flow meters, and water flow rate sensors, utilizing remote communication through transmission equipment Function: Summarize data to the monitoring center for data aggregation, integration, and analysis, and build multiple intelligent applications suitable for management. Once abnormalities are detected, they are promptly alerted through sound and light alarm lights, high pitched speakers, etcVarious methods such as LED intelligence boards, phone and text message notifications are used to issue warnings, provide timely reminders, evacuate or manage and dispatch. finally formedperception-Transmission Monitoring Warning EvacuationThe complete flood prevention and drainage management loop effectively ensures the safety of people's lives and property, and enhances the government's information technology level for flood prevention.

1、 Monitoring of Rainfall

Rainfall is the direct cause of urban flooding, and heavy rain is a severe test of a city's drainage system. Effective monitoring of rainfall can enable early perception of the flood prevention and drainage situation in the region, enabling timely response. The system uses high-precision stainless steel tipping bucket rain gauges to monitor rain conditions in real time, with a resolution of0.1mm/0.2mm/0.5mm, And automatically calculate the minute rainfall, hour rainfall, daily rainfall, monthly rainfall, annual rainfall, total rainfall, etc., and remotely transmit them to the regulatory platform of the government regulatory department through 4G/Ethernet, providing data basis for the analysis and decision-making of the management department.

2、 Monitoring of accumulated water (roads, tunnels, subways, garages, overpasses, culverts)

Heavy rainfall is most likely to cause a large amount of water accumulation on urban roads, tunnels, subways, garages, overpasses, and subway stations, seriously affecting people's normal lives and transportation. In addition to monitoring rainfall, real-time monitoring of water accumulation status is also necessary to facilitate flood control departments to grasp the water accumulation situation in various places and handle traffic dispatch in a timely manner.

Electronic water gauges can be used for monitoring water accumulation in urban roads, tunnels, subways, garages, overpasses, and subway stations. Electronic water gauges have the characteristics of high accuracy and maintenance free. Install the electronic water gauge in a suitable location, such as at intersections, bridgeheads, tunnel entrances, subway entrances, garage entrances, and other prominent locationsLED display screens, high pitched speakers, alarm lights, etc. When there is excessive water accumulation, the water level data is uploaded to the management platform in real-time through the cloud configuration screen (telemetry integrated machine), informing relevant management departments to respond in a timely manner; On the other hand, it is remotely transmitted to the position of the LED screen intelligence board, displaying the current water depth in real time, and cooperating with high pitched speakers for real-time broadcasting, warning lights, and other methods to remind pedestrians and vehicles not to pass. Remote linkage control of water pump pumping operation and lifting rod is possible, and the system is equipped with high-definition cameras to promptly report the water accumulation and level situation on site.

3、 Monitoring of water level, flow velocity, and flow rate (drainage stations, flood discharge outlets, reservoirs, rivers, lakes)

When the rainfall is too heavy and the urban drainage is not timely, a large amount of accumulated water flows into the river through drainage stations and spillway outlets, causing the river and reservoir to rise rapidly in a short period of time. When the river water rises above the riverbank, it will seriously threaten the personal and property safety of residents, buildings, etc. next to the river. So water level monitoring of rivers is particularly important, which can effectively prevent the occurrence of flood season disasters.

The system uses an input type liquid level gauge/Ultrasonic water level gauge/radar water level gauge, Doppler ultrasonic flowmeter, flow velocity sensor, water quality sensor and other monitoring equipment, real-time monitoring of river water level, water flow rate, flow velocity and other data. Powered by solar energy and lithium batteries, the system can achieve long-term continuous online monitoring 24/7 without power or human supervision. The cloud configuration screen (telemetry integrated machine) remotely uploads data information, and the management personnel can set the upper limit threshold of the water level. If the threshold is exceeded, an automatic alarm will be triggered to remind the management personnel to take emergency measures to avoid danger in a timely manner.
