Water conservancy remote monitoring system - solution

　　Fully implement the remote video real-time monitoring system of the water conservancy system, conduct real-time dynamic monitoring of possible or ongoing flood, dangerous and disaster situations, timely take preventive and remedial measures, and comprehensively improve the effectiveness and reliability of flood control and flood fighting work, which plays an important role in reducing flood disasters, relieving flood control pressure and ensuring the safety of people's lives and property.

　　Remote wireless monitoring system for reservoir dam

　　The monitoring points of reservoir dams are generally distributed in a wide range and far away from the monitoring center. At the same time, it is often difficult to erect cables due to obstacles such as rivers and mountains. The remote wireless monitoring system based on WLAN technology does not need to lay network cables, and can quickly and easily set up front-end monitoring equipment where monitoring is needed. It has strong practicability, flexibility and expansibility. The wireless monitoring system is implemented for the reservoir dam,

　　Can achieve:

　　Real time remote monitoring of key areas of the reservoir, such as the key monitoring of gate opening and dam stability

　　During the flood season, the safety and defense work of the reservoir shall monitor whether the water level of the reservoir exceeds the warning line at all times

　　Real time remote monitoring of the water bank of the reservoir, such as whether objects (such as people and animals) enter the gate and other dangerous areas

　　Real time remote monitoring of the water surface of the reservoir, such as whether there are floating objects and drifting objects on the water surface

　　Transmit the water quality detection information of the reservoir to the monitoring center at any time

　　Real time monitoring of weather conditions in the reservoir area

　　Remote command and dispatching of on-site work of reservoir by monitoring center

　　A reservoir dam needs to build a wireless monitoring system, with a total of 10 front-end monitoring points to monitor the key flood control parts such as the reservoir dam, spillway and gate in real time. It is required to collect and transmit video images within about 1km of the monitoring point 24 hours a day. Some monitoring points need to ensure that the mark reading of clear water ruler pile can be seen at night.

　　Each monitoring point includes image acquisition and processing system and wireless transmission base station. The former is composed of camera, searchlight, PTZ / spotlight control system and video server. The wireless transmission system is composed of axelwave carrier level wireless bridge and antenna feeder system.

　　The monitoring center is located in the central control room of the reservoir authority. The central base station adopts axelwave carrier level wireless bridge and antenna feeder system to form a wireless transmission network in a point-to-multipoint manner. The monitoring center remotely controls the camera focal length and PTZ movement, and takes real-time pictures of the reservoir area, water level, dam body, spillway dam section, gate opening, under the dam and water discharge. The monitoring image is transmitted to the monitoring center through wireless network. The monitoring center can watch multiple clear and real-time monitoring images at the same time, and complete the recording and archiving of monitoring image data.

　　Remote wireless monitoring system of hydrological station

　　Water conservancy station is the basic station for collecting water information and the basis of hydrological work. The hydrological station network continuously observes the surface water, groundwater volume and water quality of rivers, rivers, lakes and reservoirs in China, and collects hydrological and water resources data in real time, which plays a very important role in the development, utilization, management and protection of water resources, realizing the rational allocation of water resources, improving the utilization rate of water resources and improving water ecology. At the same time, it also provides a timely and accurate decision-making basis for the command and dispatching of flood control and moisture-proof.

　　Build a remote real-time monitoring system for water conservancy stations to realize real-time monitoring of aboveground and groundwater information, implement comprehensive video monitoring of water sources and management areas, and transmit the basic information such as on-site collected data, images, sound and video to the monitoring center in real time, so as to greatly improve the accuracy of measurement and reporting work and improve the work quality of traditional monitoring, Realize the collection, monitoring and unified management of real-time hydrological information.

　　Water conservancy stations are generally widely distributed in geographical layout, complex terrain, remote location and far away from the monitoring center. Using the traditional wired connection method, it is not only costly and long construction cycle, but also difficult to erect cables due to obstacles such as rivers and mountains. More importantly, the disaster resistance of wired transmission is relatively poor. In severe environments such as strong winds, rainstorms and crevasses, The wired line is very easy to be damaged, and the hydrological monitoring information will not be transmitted in time, which is difficult to meet the high reliability requirements of hydrological information security.

　　The water conservancy wireless monitoring system has good disaster resistance to ensure that the hydrological information acquisition system can operate normally under all kinds of bad weather conditions; Convenient installation, no need to lay network cables, which can save a lot of investment; It has strong flexibility and scalability. By setting up monitoring camera equipment and wireless base stations at the places that need to be monitored, the expansion of the system can be realized quickly, and the automation, digitization and networking of hydrological information collection can be realized step by step.
