Smart water conservancy construction dynamic monitoring and early warning solution
1. Industry background
Reservoir dams, as important water conservancy project hubs, exert huge engineering benefits. Reservoir dams not only make great contributions to flood control and flood control and ensure safety, but they also take care of the important tasks of farmland irrigation, power generation, and drinking water for people and animals. However, water conservancy dams and reservoirs themselves have potential risks. In harsh geological environments and complex climatic conditions, the stability of dams and slopes will be severely tested. For example, excessive water levels, flash floods, earthquakes, etc. can easily lead to disasters. In order to improve the safe operation and management of reservoirs, the government has introduced corresponding policies and measures. At the same time, it is currently necessary to use a variety of intelligence and informatization to manage reservoirs and provide real-time early warning of the danger of reservoir instability and landslides. How to use advanced technologies such as the Internet, cloud computing, and GIS to improve the management efficiency and social service level of the water conservancy department and promote the construction of water conservancy informatization brings new challenges to the video monitoring of the stability of reservoirs and dams.
2. System plan
Current reservoir management has problems such as scattered sites, high safety hazards, remote locations, unchanged traffic, network cabling, lack of information and data, and few management personnel and inadequate supervision. The SkeyeVSS reservoir video surveillance system sets up multiple video surveillance points at the reservoir water outlet and commanding heights to monitor reservoir water conditions, dam safety, and reservoir environment video to monitor reservoir data in real time, improving safety management efficiency. The system is mainly composed of data collection, data transmission, data processing, reservoir management platform and application systems.
3. System functions
1. Real-time video recording
Set up monitoring points at the dam outlet and the commanding heights of the reservoir to monitor the water outflow from the reservoir, install PTZ cameras to monitor the water surface of the reservoir, and prevent non-reservoir managers from entering the reservoir control area; set up water level monitoring points to monitor the water level of the reservoir , to grasp the storage capacity of the reservoir. Real-time monitoring of water color, floating objects, abnormal conditions, etc. in the reservoir makes management more timely and efficient. The following picture shows a reservoir management platform in Chengdu:
2. Voice intercom and shouting
Through the voice intercom function, the command and dispatch announcement of the work site can be realized, as well as the communication and intercom with the reservoir management personnel. Specifically, it includes: supporting direct announcement between the platform and the equipment; direct announcement to non-staff members who are close to the reservoir area. Persuading people to leave acts as a deterrent. It also supports voice intercom connected to GB/T28181 protocol, Hikvision SDK, Ehome protocol, etc., and supports audio noise reduction and echo processing.
3. Real-time data collection
Collect a variety of monitoring data in real time, including dam surface deformation, pore water pressure, leakage, reservoir water level, flow, air temperature, water temperature, rainfall and other data to provide timely and accurate data support for water storage and diversion, flood control and drought relief. It is an important measure for disaster prevention and reduction.
4. Alarm reporting and message push
The platform can provide timely and intelligent alarms for alarms uploaded by monitoring equipment (offline, occlusion, fault, etc.) and abnormal conditions monitored by AI, and provide visual pop-up reminders and notifications to facilitate real-time viewing and processing by managers. In addition, the platform can capture the alarm status and information recorded by all devices, intercept videos based on device alarm information, and obtain video screenshots at the alarm moment, etc.
Alarm messages can be pushed to managers through voice, SMS, APP, message notifications, WeChat, etc., making it easier for managers to view and handle them in a timely manner.
4. Platform advantages
1. Support multi-platform cascading, support Hikvision, Dahua, Uniview VMS, EZVIZ and other cloud platforms
2. Provide an API interface to facilitate the addition of third-party algorithm models and integration with other platforms, allowing the integration of other systems and devices through API, SDK, Onvif, EHOME, GB/T28181, etc.; provide RTSP, RTMP, HTTP- FLV, HLS, RESTAPI, Web Socket, etc.
3. Good equipment compatibility: The platform is compatible with many types of front-end monitoring and other equipment, and has good reuse scenarios. During the project implementation process, it will be transformed in a reuse manner and integrated into the entire network. There is no need to replace equipment in large quantities, which not only simplifies the implementation process and difficulty, reduces capital investment, but also does not require more energy in management and maintenance.
SkeyeVSS focuses on the in-depth integration of information technology, communication technology, and visualization technology, providing the output of video big data empowerment, AI empowerment, informatization, and intelligent empowerment technology for reservoir management. The platform has the capabilities of massive data aggregation and management, intelligent distribution, computing, storage, etc. Based on cloud service capabilities, the platform can realize cloud, edge, and terminal collaborative management, resource scheduling, computing power allocation, etc. for edge terminals and device terminals. Multi-link aggregated transmission, remote centralized management, multi-terminal, multi-protocol concurrent output, covering data collection, transmission, management, storage, concurrency and visualization, providing an overall solution integrating software and hardware.
