Abstract

The invention discloses a wireless entrance guard control system which mainly comprises five layers, namely a main server layer, an embedded server layer, a WiFi transport layer, a ZigBee coordinator control layer and a ZigBee node control layer, wherein the various layers can be flexibly matched to form six systems adapting to different application scenarios. According to the system, the ZigBee and WiFi wireless communication protocols are adopted and are combined with the embedded processor integrated management entrance guard system, the wiring is saved, lots of manual labor and wire cost can be saved, and the system has the characteristics of extremely low node / terminal power consumption, low cost and central controller update real-time property and is suitable for popularization and application.

Description

technical field [0001] The invention relates to a wireless access control system, in particular to a comprehensive management access control system using ZigBee and WiFi wireless communication protocols combined with an embedded processor. Background technique [0002] The access control system has become the most important security equipment in developed countries and regions. Different from traditional security equipment, it changes passive monitoring and alarm to active control and plays a higher security role. Therefore, access control systems are becoming more and more dominant in the field of security equipment. According to the survey results of American authoritative organizations: in the 1990s, the sales of access control equipment in the United States accounted for 57.8% of the sales of the entire public security industry; It accounts for 39.2%; in addition, in the annual survey report of Taiwan's security equipment market, the sales growth rate of access control e...
