Information

Sea area dynamic video surveillance management system

1. Project background

The sea area under the jurisdiction of our country is about 3 million square kilometers, accounting for 24% of the total land area of our country. It is an important basic resource of the country and a foundation and carrier for the development of the marine economy. In recent years, China's marine economy has developed rapidly, and the demand for the use of sea areas has continued to increase. In 2005, the total output value of China's main marine industry has reached 1.6987 trillion yuan. The newly-added area of the sea area in the country is 270,000 hectares. Higher requirements.

Since the promulgation of the "Law of the People's Republic of China on the Administration of Sea Area Use" in 2002, China has begun to implement the three systems of marine functional zoning, application for examination and approval of sea area use, and paid use of sea areas. A lot of work has been done to develop marine resources and speed up the development of the marine economy, and has achieved remarkable results in the management of sea areas, effectively alleviating the "disordered, inadequate, and unpaid" situation in the use of sea areas. As of the end of 2005, the nationwide sea area has been determined to be 9519.8 square kilometers, and the levy on sea area use has reached 1.05 billion yuan.

Although the use and management of sea areas have legal basis and guarantees, due to the current backward monitoring and monitoring methods, it is difficult to effectively monitor sea space projects, sea functional areas, and reclamation projects in recent years. The current status of sea area use Unclear with the dynamics, the lack of basic information for sea area management, and high-level information services such as dynamic evaluation and decision support for sea areas are even more impossible to talk about. The problems of unreasonable sea use, serious waste of resources, and degradation of important ecosystems have become increasingly prominent, which has seriously hindered the sustained and stable growth of the marine economy. Under such circumstances, ocean management departments at all levels urgently need the state to establish a dynamic monitoring and monitoring management system for the use of sea areas, so as to improve the management capability and level of sea area use.

Under such circumstances, the state proposes to establish a dynamic monitoring and management system for the use of sea areas, in order to keep abreast of the use of sea areas and their dynamic changes in time and space, to effectively use the resources of sea areas, and to make the best use of their benefits. The details include:

(1) Obtain real-time and accurate information on the use of sea areas, maintain the current status of data and update it in a timely manner, and provide reliable and accurate basis for the country to formulate macroeconomic decisions such as marine economic development plans and sea area resource utilization plans;

(2) Carry out rapid daily monitoring of areas that are illegal or suspected of illegally using the sea and other special circumstances to provide a basis for investigation and handling of illegal sea use and handling of emergencies;

(3) Seeking a configuration plan that achieves the best overall benefit of the use of sea areas, to meet and coordinate the demand for sea use by various sectors of the national economy, and further promote the development of the marine economy;

(4) Determine the continuous utilization of sea area to promote the maintenance and utilization of sea area resources;

(5) Establish and improve the digital, visual and networked information expression methods of sea area management, and realize the scientific, information and standardization of sea area use management;

(6) Provide sea-related data, maps, and technical information to the sea-related public to fully serve the society.

2. Demand analysis:

China is one of the earliest countries in the world to use water transportation. With the development of transportation, water transportation requires that the waterways of various water systems communicate with each other and be connected into a network. The waterway safety management department needs to understand the normal running of ships, overweight conditions and seek help in real time. Search and accurately locate, and record the number of the ship entering the area for future inquiry.

China is constructing "digital water conservancy" and "smart water conservancy", comprehensively building a remote real-time video monitoring system for water conservancy systems, and real-time dynamic monitoring of possible or ongoing floods, dangers, and disasters, and taking timely preventive and remedial measures can comprehensively improve flood prevention. The effectiveness and reliability of anti-flood work has an important role in reducing flood disasters, relieving flood control pressure, and ensuring the safety of people's lives and property.

With the development of safety informatization, traditional monitoring equipment has been unable to meet the application requirements of large-scale safety management of waterways and waterways due to the problems of small monitoring range, low resolution and poor night vision. The channel digital remote day and night monitoring system can achieve a monitoring distance of tens of kilometers. With the maturity of the fog-passing imaging technology, the monitoring ability of various weather environments has been greatly improved; with the digital channel visualization
