1. Project background
Reservoir safety during flood is the top priority of flood prevention and flood fighting in the country, and the reservoir monitoring system is an important engineering measure for reservoir risk relief. Reservoir sites are generally widely distributed geographically, with complex terrain and remote locations, and are far away from the monitoring center. The traditional wired connection method is not only expensive, but also has a long construction period, and it is often difficult to erect lines due to obstacles such as rivers and mountains. More importantly, cable transmission is less resistant to disasters. In harsh environments such as strong winds, heavy rains, and ruptures, cable lines are easily damaged, and hydrological monitoring information cannot be transmitted in time, making it difficult to meet the high level of hydrological information security protection. Reliability requirements.
Therefore, the reservoir management department can build a "reservoir monitoring system" to remotely monitor the water level, rainfall and on-site images of each reservoir, and provide accurate and timely on-site information to ensure proper water storage and safe flooding of the reservoir.
2. Demand analysis
1. During the flood season, always pay attention to the water level of the reservoir. If the water level reaches the warning line and there is a dangerous situation, call the police immediately;
2. Prevent key areas of the reservoir, pay attention to the normal operation and stability of the gates and dams at all times;
3 , Real-time remote monitoring of the water surface of the reservoir: Whether there are floating objects (such as white garbage) and floating objects (such as leaking crude oil) on the
water ; 4. Real-time remote monitoring of the water surface of the reservoir: Objects on the shore (such as people, Whether the animal enters the dangerous area (such as the gate, the levee), whether there is any suspicious situation (such as someone wants to destroy the reservoir);
5. The water quality of the reservoir can be detected at any time, and the information can be transmitted to the remote end to find the water quality If the limit is exceeded, the alarm will be reported immediately;
6. Real-time monitoring of the weather conditions of the reservoir;
7. The voice communication between the remote control center and the reservoir site can perform remote command work in case of a situation.
3. Project construction
In response to the above requirements, TSINGSEE Green Rhinoceros Video recommends using Haikang’s 4G pan-tilt machine with a third-party wind and solar complementary system. The platform uses the EasyCVR integrated intelligent security system, which can support the access of multiple device protocols and realize video structuring. , And supports hierarchical management of roles. At the same time, you can view cloud or device-side video. If the device supports it, you can get the latitude and longitude of the device. Supports outputting videos to third parties through API, sharing page, GB28181, etc. In the flood control stage, you can watch the real-time on-site situation of the reservoir through the app or the big screen, and you can also call the equipment side video.
Realization process:
1. Install a 4G optical splitting complementary camera in the reservoir;
2. Through configuration, connect relevant equipment to the EasyCVR platform through the corresponding protocol;
3. Cloud video recording and screenshots can be performed through configuration or calling;
4. Equipment can be retrieved Side video;
5. Configure API interface or GB28181 hierarchical information to share the video with the government or other third parties.
Four, system function
The EasyCVR reservoir video monitoring system fully integrates software and hardware equipment resources, can realize all-weather remote automatic monitoring of the monitored reservoir, and can completely record the dynamic change process of each reservoir data. EasyCVR adopts B/S structure design, users can remotely access through LAN or WAN.
- It can realize the real-time call of audio and video at the station end, and record uninterrupted video 24 hours a day, the video effect is clear and recognizable, and the video data is stored for more than one month;
- Realize the anti-theft and surrounding prevention of each water conservancy station, upload the alarm and video pictures to the monitoring center in real time when there is an abnormal situation, and have a local warning function;
- Real-time check the operation status of the equipment in the key computer rooms and equipment rooms in the subordinate stations;
- Need to know the temperature and humidity of the communication room and battery room at any time;
- There must be detailed identity records and operation information records for personnel entering and exiting the reservoir;
- Realize real-time two-way intercom between on-site maintenance personnel and center staff;
- Realize water leakage detection in key computer rooms;
- There are corresponding emergency, alarm and linkage measures for any monitoring information;
- The system has a multi-level structure and authority management to ensure that township and county level staff can complete their work under the same system.
The reservoir monitoring system fully combines user needs and reservoir site conditions, and uses unique low-power monitoring equipment, which not only saves equipment costs, but also reduces the difficulty of construction. On the basis of fully satisfying the needs of users, the reservoir monitoring system also designed functions such as trend analysis, SMS alarm, and multi-center monitoring, which truly achieved real-time monitoring of the water and rain conditions of the reservoir and realized the information management of the reservoir.
