Campus security monitoring system based on Zigbee network

Abstract

The invention discloses a campus security monitoring system based on a Zigbee network. The campus security monitoring system comprises a security monitoring center, an aggregation node, a passive Zigbee node and an active Zigbee node, wherein the passive Zigbee node and the active Zigbee node are respectively connected with the security monitoring center through the aggregation node; the passive Zigbee node comprises a passive audio Zigbee node and a passive video Zigbee node; the passive audio Zigbee node comprises an audio detector, an awakening control unit, a micro processor, a Zigbee radio frequency module and a battery; the audio detector, the awakening control unit, the micro processor and the Zigbee radio frequency module are sequentially connected with one another; and the battery is connected with the audio detector, the awakening control unit, the micro processor and the Zigbee radio frequency module respectively.

Description

technical field [0001] The invention relates to a safety monitoring system, in particular to a campus safety monitoring system, in particular to a Zigbee network-based campus safety monitoring system. Background technique [0002] School safety work is a very important part of the safety work of the whole society. It is directly related to whether young students can grow up safely and healthily, and it is related to the happiness, tranquility and social stability of thousands of families.
