Analysis of the principle of network design of YouAn Hong XueLing project

The "Snow Leasing Project" is based on the mass prevention of the county, township and village three-level comprehensive management centers as the command platform, comprehensive information management as the support, grid management as the basis, and public safety video surveillance network application as the focus. Control Engineering." It extends the preventive measures to the masses through the construction of a three-level comprehensive management center, mobilizes social forces and the masses to jointly monitor video surveillance, and participate in the prevention together, thereby realizing prevention and control of “full coverage and no dead ends”. Because "the eyes of the masses are bright," they are called "snow projects."

Design Principles

According to the requirements of the construction goals and the nature of the system, we first determine the design according to the following principles:

Safety, reliability and stability

The stability of the system means that the system has the ability to run continuously for a long time, and the hardware and application software system design can withstand the test of long-term operation. In the design and implementation of this system, the principles of safety and reliability are achieved through the following means: High-performance, high-reliability products are adopted in the selection of major equipment; hot-backup methods are used for key boards; and the entire application system is designed and implemented. In strict accordance with China's communications command industry standards, in order to ensure the system's safety, reliability and stability principles.

The principle of technological advancement

Based on the consideration of the performance of the entire system and future development trends, the technology is changing with each passing day, and maintaining certain advanced nature, the system can stand the test of time and ensure that the adopted technology will not be eliminated soon. In this system, advancement refers to the advanced overall architecture of the system, advanced host control systems, and advanced computer network technology. Make full use of the functions provided by the system software to provide users with an easy-to-use, easy-to-maintain operating platform that is easy to upgrade.

Economic principle

By grasping a trade-off relationship between system cost and technological advancement, we can strive to pursue an optimal performance/price ratio through the autonomous development of application systems while maintaining the advanced nature of the system's basic technology, and fully consider the overall ownership of the system. The cost makes the system build on a relatively high technical level, and reduces the user's initial construction cost and post-maintenance cost. In this project, we maximized the system performance and reduced the product price of the entire system, and strive to make it the most cost-effective light engineering intercom broadcasting assistance system.

Principle of operation and maintenance simplicity

Operators only need some basic knowledge and can quickly perform system operations without long and complicated training. When problems occur in the system, they can be quickly restored through simple technical processing, and system upgrades and maintenance are simple.

The system is built on a graphical user interface. As long as the operators are familiar with the operation of the Windows environment, they can work quickly.

We provide complete instruction manuals for the entire system, and provide strict training for the user's network management and related personnel to help users quickly grasp the use and maintenance of the system.
