Enterprise-level comprehensive security platform system design. Functional design The enterprise-level comprehensive security platform designed in this paper is mainly based on video surveillance system, integrated with alarm system (including intrusion alarm, perimeter alarm, etc.), entrance and exit control system (including access control system, identification system, etc.), security electronic patrol System, etc.; support analog and digital acquisition and monitoring; convenient integration with video conferencing systems, command and dispatch systems, and information management systems.

System Level Design This paper adopts the layered design mode for the enterprise-level integrated security platform. The layered design pattern has the following design principles: 1 “high cohesion, low coupling” principle, which allows developers to focus on only one of the entire structures. One layer; it is easy to replace the implementation of the original level with a new implementation; it can reduce the dependence between layers; it is conducive to standardization; it is beneficial to the reuse of logic at each layer. 2 layer by layer calling principle and one-way calling principle, the first M (1 The common device access middleware mainly includes a serial port access module, a network access module, a serial port network port access module, an SDK calling module, etc., and provides access to various devices, and provides a unified interface after unified packaging of devices of different manufacturers, which is convenient for future The dynamic increase of different types of devices means that devices of different manufacturers can be added at any time.
