Meteorological, environmental protection, water conservancy remote monitoring applications

The water level monitors flood control, illegal sewage discharge monitoring, environmental protection, and prevention of damage. Through real-time video monitoring, the supervisory department can timely know the police situation and take corresponding countermeasures; through video storage, the purpose of obtaining evidence and investigating afterwards can be achieved.

With the rapid development of the national economy, water conservancy projects play an increasingly important role in the national economy, and flood control is an important aspect that directly affects the development of the national economy. The flood control dam centralized monitoring system truly reflects the modern management and intelligent operation of flood control. Early warning of the water level of the flood control dam has won valuable time for leading decision-making and reducing losses caused by floods, and effectively safeguarding the safety of people's lives and property. Due to the low level of information coverage of water related projects, in the flood season or the dry season, field data collection is mainly carried out by manual methods. In such a work environment, data collection has a great delay, especially in the event of an abnormal situation, the accuracy and efficiency of information transmission, will greatly affect the safety of life and property of the majority of residents. In recent years, the state has proposed the goal of building “digital water conservancy”. Fully implement the informatization construction of large reservoirs. On the one hand, speed up the informationization process of water conservancy projects and improve the efficiency of their construction. On the other hand, the work of flood control and drought relief can be gradually changed from passive to active, and the impact of disasters can be minimized through a perfect early warning mechanism and emergency command system.

When in the flood season, the relevant staff will need to monitor the operation status of the reservoir dam in a mobile manner, and transmit the images of some abnormal conditions to the monitoring center in the first time. Real-time monitoring of possible or ongoing public opinion, danger, and disaster situation, keeping abreast of the situation at the scene, so as to take appropriate preventive and remedial measures to ensure the safe operation of the reservoir. It plays an important role in leading decision-making and reducing flood disasters, eliminating hidden dangers in flood season, alleviating urban flood control pressure, warning of dangerous conditions, and ensuring the safety of people's lives and property.

According to the characteristics of water conservancy projects and water conservancy industries in the past, monitoring projects for important facilities such as reservoirs and rivers often involve a wide geographical range, scattered monitoring points, and more network monitoring users. Each water conservancy department needs layer-by-layer supervision. For large-scale monitoring projects, the requirements for system stability are relatively high, and it is necessary to minimize the maintenance of equipment in the future. To this end, Hefei Technology has designed a remote video surveillance system based on 3G network for this water conservancy monitoring project. Program.

Due to the special nature of the monitoring environment, the reservoirs, rivers and other sites lead to fiber and wiring difficulties. Wireless monitoring is widely used in the water conservancy industry because of its high flexibility, strong scalability and simple maintenance.

The equipment in the flood season uses solar energy, wind power supply, field poles, and adopts the method of timing capture of high-definition pictures. The 3G network is used to timely transfer the water level pictures to the water conservancy monitoring command center, and simultaneously collect environmental parameters such as water temperature for decision-making.

The main contents of the monitoring are:

In the flood season, the reservoir safety and defense work, always pay attention to the water level of the reservoir. If the water level reaches the warning line, there is danger and immediately report to the police.

Prevention of key areas of the reservoir, paying attention to the normal operation and stability of the gate and dam

TV station real-time coverage, wedding company, party, exhibition, outdoor sports live video live

In order to report the sudden time in the first time, TV stations usually need to use expensive OB vans, but the response speed is too slow. Therefore, TV stations, radio stations, news websites, and newspapers have the demand for devices that use more convenient and quick text reports. 3G live broadcast instrument based on 3G image transmission technology came into being. Unlike video surveillance in the security industry, it needs to support more kinds of video sources. Digital HD and analog A/V input coexist, flexible switching, mainly HD-SDI video output of professional video cameras, higher sound quality, picture quality, etc., usually require more 3G card bundles, and complementary network support of heterogeneous operators.

Such applications can also be extended to the civilian sector. Typically, for example, wedding companies can use this type of equipment to provide newly-married customers with a live broadcast of the wedding, so that relatives and friends who are unable to visit the site in the field can feel as if they are on the scene. The joy of the children.
