Background Overview
Affected by various factors such as China’s special natural geographic environment, extreme disastrous weather, economic and social activities, etc., China’s floods are serious, and sudden local extreme heavy rainfall triggers frequent mountain torrent disasters, mountain torrents, landslides and geological disasters It has the characteristics of suddenness, fast flow rate, large flow, large material capacity and strong destructive power. Once it occurs, it will cause serious harm to the national economy and people's lives and property.
In order to improve the monitoring and early warning capabilities of mountain torrents, and to strengthen the rapid response capabilities when disasters occur, the State Council approved the Ministry of Water Resources to issue the "National Mountain Flood Disaster Prevention Plan" to "speed up the implementation of mountain torrent disaster prevention and control plans, strengthen the construction of monitoring and early warning systems, and establish grassroots Defence organization system and improve mountain torrent disaster defense capabilities", and the establishment of a mountain torrent disaster early warning system is an important non-engineering measure for the country to prevent and control mountain torrent disasters.
Program requirements The
mountain torrent disaster monitoring and early warning system is an important non-engineering measure for the prevention and control of mountain torrent disasters. It integrates information collection, transmission, analysis, and early warning. It realizes the timely and accurate upload and distribution of early warning information, so as to make possible disaster areas Able to take timely measures to minimize personnel and property losses.
System composition The
mountain torrent disaster monitoring and early warning system is composed of front-end data collection equipment, power supply equipment, transmission equipment, monitoring center and mobile APP. The front-end data collection host passes the collected video images, water level, rainfall, water temperature, air pressure and other data through 2G /3G/4G/5G/NB-IOT and other wireless methods are transmitted to the monitoring center. The monitoring center software can display and analyze the data collected by the front-end equipment. The mobile APP can view the current rainfall information and water level information in real time, and will send out when there is an alarm. Early warning information reminds relevant commanders to prepare for rescue work.
System features
Real-time data: Real-time collection of rainfall information, and real-time rainfall information sent to the mountain torrent business platform, so that flood control staff can obtain information in time, and provide support for mountain torrent early warning and decision-making.
Automatic alarm function: real-time monitoring of rainwater data, when the monitoring data exceeds the threshold, the simple rain alarm will send out an early warning bell to realize the early warning alarm directly to people and increase the transfer time of the masses.
Strong stability: The early warning system uses a variety of communication methods to integrate and use, and it can still work normally under the conditions of network or power outages, ensuring uninterrupted monitoring of mountain torrent disasters, and protecting people's lives and property.
Diversified early warning methods: manual early warning, sound early warning, SMS early warning, broadcast early warning, all-round early warning means allow early warning information to be communicated to everyone.
Project value The
mountain torrent disaster monitoring and early warning system is designed from the demand level, combined with mountain torrent prevention and flood control, and provides multi-level information display services. Taking the pre-plan as the main line and event-driven, through the activation of boundary conditions of the monitoring data and the pre-plan, the automatic analysis of the early warning response level and the next work deployment, and the information linkage of the provincial, city, county, and township flood control information platform to achieve flood control The rapid and effective development of services such as, drought relief, and wind protection, while customizing different information service products to meet the needs of integrated flood control business management.
