Security system construction and design requirements


The construction of security system will follow the principle of advanced technology, complete functions, stable performance and cost saving under the premise of pursuing superior performance and economy. Try to make the system an information platform that meets the practical application of the chain industry. With comprehensive consideration of maintenance and operational factors, there will be room for expansion for future development, expansion and transformation. The system is designed to pursue five unifications, and strive to find a unified combination point and entry point.
?1 Unity of practicality and economy
Adhere to the principle of practicality. The system should be able to meet the monitoring requirements of the chain industry system to meet the business needs of system administrators and users, and be able to adapt to the development of new technologies. At the same time, efforts should be made to reduce construction costs and select products with mature technology and stable performance and cost performance. And make good use of existing equipment as much as possible to reduce waste.
?2 Unity of rationality and advancement
The design of the system scheme strictly follows the design criteria of the system engineering, and achieves a balance between the rationality of the system and the advancement of the technology. Efforts should be made to pursue the scientific rationality of the entire system function, and to prevent one-sided pursuit of a certain high index and advancement. Under the premise of ensuring the function and performance of the whole system, the ground adopts mature technology that can inherit and have broad development prospects.
?3 Standardization and openness
The system design adopts standardized modular design and strictly abides by the international and domestic standards of related technologies to ensure open transparency between systems and interconnection between systems. Considering that the whole system is constructed in phases, when designing and selecting equipment for subsystems with extended requirements, the system should be designed based on the scientific prediction of future business growth and expansion, and reserved for expansion. And the space for development.
?4 Unification of reliability and safety
The whole system adopts the overall design with high reliability. The selected equipment should have high reliability. The key equipment or key components should adopt backup redundancy design, select the mechanism to improve the system software with high security level, and use reliable function. Dedicated network products.
?5 Uniformity of manageability and ease of maintenance
The system should be easy to manage and maintain. With the special tools such as the network management system self-diagnosis program, the operation status of the network or other equipment can be easily monitored to solve the problems in time; the information infrastructure of the computer network should be designed to be simple and easy to use. Architecture to reduce system operation and maintenance costs. In order to ensure the after-sales service of products, we should choose domestically-branded products with mature technology.
