During the rainy summer season, flood prevention and control have become the main tasks, so it is essential to deploy flood prevention facilities in advance for cities.
In order to cope with the severe pressure of flood control in the flood season, a command system for flood control and typhoon prevention in Shanghai has realized the real-time monitoring and disposal of rainstorm early warning, ponding forecast, ponding change, emergency disposal, etc. through the use of camera and sensor monitoring technology. For example, cameras are used for water accumulation monitoring, while over 5000 sensors are used for online monitoring of the situation.
The system runs 24 hours a day and monitors in real-time. After receiving the backend alarm, relevant departments will immediately dispatch personnel to the scene for disposal.
In the past, the rise in water level was only detected passively, for example, when citizens discovered it and reported it to the hotline, the disposal situation was not connected to the internet. At present, the city has installed more than 5000 various types of neural sensors, which transmit data to the background every 5 minutes, turning passive into active. For example, underpasses are often prone to water accumulation, and "electronic water gauges" have been installed in over 400 underpasses.
The application of sensor technology enables us to shift from passive to active during the flood season, allowing us to grasp the flood situation and take timely measures without leaving our homes, greatly reducing the severe pressure of flood prevention!
Electronic water gauge
Electronic water gauge is a hydrological detection device used to directly observe water levels. When the water level reaches the warning level, the sensor will automatically alert the system, and relevant departments will immediately arrange personnel to handle the situation upon receiving the information. When the accumulated water reaches the hazardous level, relevant data will be synchronously pushed to the public security department, road transportation department, etc., and multiple departments will work together.
Smart manhole cover&water level gauge
The smart manhole cover can remotely view parameters such as battery voltage, manhole cover angle, signal strength, water level, etc., achieving remote monitoring of the manhole cover status. When the manhole cover is opened, damaged, or misplaced, the manhole cover monitoring device can immediately sense and send an alarm to the management background, which is convenient for notifying the staff to repair and rescue in a timely manner, reducing the occurrence of danger.
When used in conjunction with an input type water level gauge, it can achieve monitoring of water level immersion. Once there is water accumulation on the road, it can promptly notify management personnel to carry out drainage and prevent road water accumulation and urban waterlogging.
Water immersion sensor
Installing water immersion sensors in areas prone to water accumulation can be used to detect the occurrence of water accumulation. Once water accumulation occurs, timely alarm can be triggered to reduce the losses caused by water accumulation. Water immersion sensors can be widely used in communication base stations, hotels, restaurants, computer rooms, libraries, archives, warehouses, equipment cabinets, and other places that require water accumulation alarms to avoid causing greater economic losses.
Rain gauge
The tipping bucket rain gauge collector integrates a high-precision RTC time module and a large capacity EEPROM storage device internally. Supports up to one month of rainfall information storage, which can be used in situations where rainfall monitoring is required.
Ultrasonic level gauge
Ultrasonic level gauge is an ultrasonic level gauge designed for monitoring the safety of engineering water bodies. It has the advantages of few accessories, easy installation, high-precision automatic observation data collection, and high reliability.
Real time monitoring of water levels in rivers, reservoirs, ponds, and other areas prone to breaches and floods using ultrasonic level gauges can effectively prevent and control the occurrence of flood disasters. Relevant departments can quickly deploy flood monitoring systems based on data feedback from ultrasonic sensors, improving monitoring efficiency and accuracy. The device can be installed on bridges, rivers, streams, and any place where remote monitoring systems need to be installed. The warning system will alert you that the water level is rising, so that the public and community can be protected from the threat of floods.
System for monitoring landslides and collapses
Continuous heavy rainfall can easily cause geological disasters such as landslides, collapses, and mudslides. Therefore, monitoring mountain displacement has become an essential task during the flood season.
AIS2000 from Huilian Technology is a sensor specifically designed to measure tilt angles, which can be used in monitoring systems for roadbed settlement, landslides, and collapses.
Through the monitoring system, real-time status information of monitoring projects can be effectively grasped, and disaster patterns can be analyzed based on monitoring data to effectively predict geological disasters. Early warnings can be given for possible disasters, and corresponding measures can be taken in a timely manner to ensure the safety of people's lives and property.
SSI100 is a high-precision settlement instrument developed by Huilian Technology, with a resolution of 0.1mm and an accuracy of 1mm, which has been highly recognized by many customers. The hydraulic settlement instrument is used for long-term monitoring of the settlement inside and outside of structures, and is widely used for monitoring the settlement deformation of dams, bridges, slopes, foundations, highway embankments, civil and industrial buildings, as well as backfill soil. The hydraulic settlement instrument is composed of silicon pressure sensors with supporting accessories, and can be deployed at a single point or multiple points for networking. The product output interface is RS232 or RS485 optional, which can be easily integrated into the user's environment. The product works with a wide voltage range, optional output rate, and is very flexible and convenient
Various sensors monitor in real-time and transmit data in a timely manner, issuing warnings in the first time, greatly expanding the guarantee capability of flood prevention and providing important support for people's safety.
In today's rapidly developing technology, sensor technology has made flood prevention and control smarter, which can be said to be invaluable!
