In recent years, global climate change has led to frequent extreme weather events, and the problem of urban waterlogging has become increasingly serious. In recent years, many places on the mainland have suffered heavy rainfall that is rare in history, causing serious losses. Take the recent floods in Meizhou, Guangdong Province, for example, causing direct economic losses of up to 4.7 billion yuan. Similar incidents are not uncommon across the country, highlighting the urgency of urban flood prevention and drainage work.
In the face of such a severe situation, how to effectively prevent and respond to urban waterlogging has become the top priority of local governments and water affairs departments. In this context, the online monitoring station of water accumulation launched by Yifan Technology came into being, providing an intelligent solution for urban flood control and drainage work.
Sekisui Online Monitoring Station: System Overview
The Sekisui online monitoring station is a set of intelligent equipment that integrates a variety of advanced sensors and communication technologies. It mainly provides real-time monitoring and early warning for urban roads, sunken overpasses and other water-prone points. The system consists of the following main components:
1. Water level monitoring station: the core component of the system, which can accurately measure the depth of water accumulation.
2. Rainfall monitoring station: collect rainfall information and record extreme weather conditions such as short-term heavy rainfall.
3. Data transmission unit: Real-time data transmission through 4G/5G or NB-IoT and other technologies.
4. Central control platform: summarize and analyze data and provide decision support.
Application scenarios and effect analysis
- The application scenarios of the Sekisui online monitoring station are wide, mainly including:
- Monitoring of water accumulation on urban roads
- Early warning of water accumulation on sunken overpasses
- River water level monitoring
- Pumping station operation monitoring
- Flash flood warning in a mountainous city
- Intelligent linkage with urban drainage network system
Typical application results
In some cities that have deployed online monitoring stations for water accumulation, the system has shown significant flood control effects:
1. Early warning time: The system can issue early warning at the early stage of water accumulation, and find problems 30-60 minutes earlier than the traditional manual inspection method on average.
2. Shortened disposal time: Due to the timely and accurate information on water accumulation, the response speed of the flood control department has been significantly improved, and the disposal time has been shortened by about 1 hour on average.
3. Reduction of economic losses: Through timely warning and rapid disposal, cities that adopt the system have reduced their economic losses related to water accumulation during the flood season by an average of 40-50%.
4. Improvement of citizen satisfaction: The deployment of the system has made the problem of urban water accumulation faster and improved the satisfaction of citizens with the city's flood control ability.
Multi-scenario applications
1. In coastal cities, the system is used to monitor road water accumulation during typhoons to inform traffic control and evacuation decisions.
2. In mountainous cities, the improved system is used for flash flood early warning, which provides an important reference for the prevention and control of geological disasters by monitoring the water level and rainfall of mountain rivers.
3. In large-scale urban complexes, the system is linked with the drainage pumping station to realize the intelligent cooperation between the water accumulation point and the surrounding drainage facilities, and further improve the drainage efficiency.
These applications demonstrate the adaptability and effectiveness of the online monitoring station in different environments. As the system is deployed and used in more cities, it is expected that more success cases and application data will be accumulated to further validate and improve the system functionality.
Big Data Application and Urban Management Optimization
Yifan water accumulation online monitoring station is not only a data collection tool, but also an important source of urban flood control big data. With long-term monitoring data, city managers can:
1. Analyze the law and characteristics of urban water accumulation
2. Optimize the design of urban drainage systems
3. Formulate a more scientific flood prevention plan
For example, in one city, a two-year analysis of water monitoring data found a number of irrational drainage network designs. Based on these findings, the city developed a targeted renovation plan to upgrade the drainage network in some key areas. This initiative is expected to increase the city's overall drainage capacity by 20-30%, which is expected to significantly reduce the occurrence of waterlogging events.
System Benefits
1. Strong real-time monitoring ability: 24-hour uninterrupted monitoring
2. High accuracy of early warning: based on accurate data and advanced prediction models
3. Wide range of application: it can be extended to a variety of water environments
4. High degree of intelligence: automatically analyze data and trigger early warning
5. Strong scalability: it can be connected with other city management systems
Challenges and solutions
Despite the bright future, the system still faces a number of challenges:
1. The initial investment cost is high
Solution: Adopt a step-by-step implementation strategy and prioritize coverage of key areas
2. Data Security
Solution: Use high-strength encryption technology to strictly manage data access rights
3. High system maintenance requirements
Solution: Develop a self-diagnosis function and train a professional maintenance team
Public participation: Build a national flood control network
To increase public participation, it is recommended that:
1. Develop a citizen version of the app to provide real-time water accumulation information and safe route planning
2. Add a reporting function to the App to allow citizens to participate in the identification of stagnant water points
3. Hold regular lectures and drills on flood prevention knowledge to raise public awareness of disaster prevention
epilogue
As a new tool for smart flood control, the online monitoring station of water accumulation under Yifan Technology is providing new ideas and methods for urban water control. It not only improves the efficiency and accuracy of urban flood control, but also provides strong support for the intelligence and refinement of urban water environment management.
With the continuous advancement of technology and the expansion of applications, such systems will play an increasingly important role in building resilient cities and addressing the challenges of climate change. All localities should strengthen the construction and application of such online monitoring and early warning systems, and at the same time strengthen publicity and education for the public, enhance disaster prevention awareness and self-rescue capabilities, and jointly build safer and more livable smart cities.
