“Digital Water Conservancy” refers to relying on modern communications, video surveillance alarms, Internet of things, computers, remote sensing, GIS, GPS, multimedia technology, large-scale storage technologies, and intelligent digital acquisition technologies to integrate water conservancy information into an immediate, manageable, A scientific platform for monitoring and dispatching; thus providing decision-making personnel with decision-making basis for water resources dispatching, disaster assessment, and flood warning, among which the monitoring and commanding and dispatching platform as the core hub of digital water conservancy system has become the entire “digital water conservancy” construction link. An important controlling node.

The State supports the development of water conservancy projects. The Central Document No. 1 has pointed out in recent years that it strives to achieve a fundamentally backward situation in water conservancy construction through 5 to 10 years of efforts. By 2020, it will basically complete a flood prevention and drought relief system, key cities, and flood protection. The flood control capability of the district has been significantly improved, and the ability to fight drought has been significantly enhanced. During the “Twelfth Five-Year Plan” period, important river sections of key small and medium-sized rivers (including Dahe-Dahe tributary, independent inflowing rivers and inland rivers) have been basically completed, and small-scale reservoirs have been fully reinforced. And the construction of early warning and forecasting systems for disaster areas prone to flash floods.

According to the Ministry of Water Resources, not only has the country proposed a target of total investment of 1.8 trillion yuan in total water conservancy during the 12th Five-Year Plan period, but in the next few years, many provinces will also invest more than 100 billion yuan in water conservancy investment.

Fujian Province proposed a 20 billion yuan water conservancy investment target for 10 years. It also established a water conservancy investment group and plans to raise RMB 50 billion in 10 years. In addition, Fujian Province also encourages cities, counties (districts) to set up water investment and financing platforms at the same level, and grant corresponding support policies.

Guizhou has played a "back-up catch-up" water conservancy investment card to accelerate the pace of cracking the engineering water shortage problem. According to Zhao Kezhi, governor of Guizhou Province, the total water conservancy investment in the province from 2011 to 2020 will have to complete 200 billion yuan, including 103.3 billion yuan during the "12th Five-Year Plan" period.

Shanxi Provincial Party Committee Secretary Yuan Chunqing met with Minister of Water Resources Chen Lei, who is currently investigating and studying in Shanxi. He said that Shanxi decided to invest 100 billion yuan in five years to accelerate the construction of water conservancy projects led by Shanxi Dashui Network Project.

Liaoning Province, where frequent floods and droughts occur in history, plans to implement 6 categories of 64 water conservancy projects in the 12th Five-Year Plan period, with more than 20,000 projects. A total investment of 90 billion yuan will be allocated, and 40 billion will have been signed with the China Development Bank. Yuan financial cooperation agreement.

Water conservancy construction brings security business opportunities The country places water conservancy work in a more prominent position in the development of the party and the country’s undertakings, and strives to speed up construction of farmland water conservancy, promote water conservancy development by leaps and bounds, and strive to increase the average annual input of water conservancy in society over the next 10 years compared with 2010. Doubled. In the next 10 years, it will exceed 400 billion yuan each year, and the investment in the next 10 years will exceed 4 trillion yuan. At the same time, it proposes to extract 10% of the proceeds from land sales for irrigation and water conservancy construction, and give full play to the comprehensive benefits of land remediation funds such as newly-increased land use fees for land for construction and land use. It can be forecasted that this measure will enable local counterpart funds to meet the requirements. It will enter the golden decade of future development.

The national investment in fixed assets for water conservancy mainly includes flood control projects, water resources projects, ecological and special projects, hydropower projects, and special projects. This has brought tremendous business opportunities to the security industry.

Status of water conservancy and security and market demand In recent years, the water conservancy departments have begun to deploy security systems to monitor the implementation of key water conservancy projects in various locations. The construction of important water conservancy and flood control projects and control gate stations has been combined into a digital, networked, and intelligent video. The monitoring system can provide real-time and intuitive sensational image information for flood prevention departments at all levels.

From the point of view of product demand, at present when implementing water conservancy projects throughout the country, security has become a necessary subproject. Apart from the water conservancy projects to be put into construction, some already-operated water conservancy projects will also be supplemented with security subsystems, but the application of the national water conservancy project security system is still low, so the demand for water conservancy and security products will show strong momentum in the next few years. .

China has conducted a preliminary investigation of geological disasters in 1,640 counties in the mountainous and hilly areas and found 240,000 hidden hazards in geological disasters. According to a report released by the Ministry of Water Resources, there are more than 1,800 counties in the country, which are already in the midst of the threat of mountain torrents. As early as July 25, 2010, Vice Minister of the Ministry of Water Resources, Jiao Yong, said in an interview that the state finance will allocate 3 billion yuan within three years for the construction of monitoring and early warning facilities in 1800 flood-prone counties nationwide.

At present, many provinces and cities across the country have installed "telescope" for flood prevention command work, built flood control communication networks and information platforms, and helped all levels of water conservancy and flood prevention departments to monitor public opinion in real time. The main function of this so-called “telescope” security system is that once a dangerous situation occurs, the system is pre-positioned in the place where the incident occurred, and the dangerous situation is automatically sent back to the mobile phone of the responsible person of the relevant local department in time, and the local area is informed by broadcasting. The masses moved in time. According to the person in charge of the National Defense Office, the early warning system is effective and will be promoted in areas with mountain flood prevention and control tasks.

The application of security equipment in water conservancy projects The water conservancy security system is a comprehensive prevention system that includes dam safety, outdoor protection, unit protection, production supervision, transmission and distribution, remote supervision, and early warning prompts. For these applications, The selected security equipment can provide security for water conservancy system equipment, prevent illegal behaviors in time, and make decisions on abnormal behaviors.

According to the different areas of the water conservancy project, targeted security systems need to be used, which can be divided into perimeter prevention, anti-theft alarm, video surveillance and other systems.

Perimeter protection system perimeter protection system is mainly applied to reservoir dams and other areas, can use infrared radiation, passive infrared, vibration cable and other facilities to protect the safety of the dam, in which the vibration optical cable using communication cable as a detection tool, by the laser transmitter The sensor receiver and sounder alarm system are used to continuously monitor the vibration, leakage, formation movement and landslide in real time, and can accurately point out the damaged or faulty sections to ensure the safety of the dam. According to Honeywell Lu Siwu: “The perimeter protection system can also be used to supervise the operation of key facilities. Due to the stringent operational requirements, access to these areas requires appropriate authority, and auxiliary equipment such as access control can be added. ."

Anti-theft alarm system The anti-theft alarm system is mainly used to prevent illegal elements from damaging or stealing water conservancy and electromechanical equipment. Therefore, various types of alarm detectors are used. They can be installed in pump rooms, water towers, and other related parts, once man-made destruction or theft occurs. , it immediately issued an alarm signal. Wang Xiaoqing, general manager of Beijing Deqing Electronic Technology Co., Ltd., said: “The water conservancy industry has a dedicated network that can connect not only provincial, municipal, and county-level water conservancy departments but also emergency command posts, public security forces, and military units. Networking, once you receive the alarm information, you can immediately send the police."

Due to the wide range of water conservancy projects and the long distances between them, the rapid development of modern communication technology and video technology has provided a powerful guarantee for the digitization of water conservancy construction. The video surveillance system is mainly used for daily management and flood prevention management. It can monitor the situation of the reservoir and the hydrological conditions in real time. The configuration control of the relevant hydrological information, gates, etc., can effectively improve the work efficiency of the water conservancy department. Expand the degree of digitization. It is mainly composed of front-end equipment, transmission equipment, and monitoring center.

In recent years, the rapid development of the security system has become an indispensable part of the water conservancy project, and it has become an essential information system for the water conservancy department. At present, the water conservancy and security system has been developed in the direction of integration, digitization, scale, and intelligence. It has gradually changed the construction methods that used to be dominated by individual water conservancy facilities, and formed a large-scale monitoring system based on watersheds. The monitoring point will also gradually realize the networking transformation and develop in the direction of multi-level networking.
