Building distributed safety control method and system based on ZigBee gateway

Abstract

The invention discloses a building distributed safety control method and system based on a ZigBee gateway, the method comprises the following steps of: receiving an acquired alarm message packet, sending a TCP short connection establishment request, receiving a message which agrees to perform TCP short connection, sending the alarm message packet and a update request, sending an instruction for opening the door, and simultaneously disconnecting the TCP short connection; and reporting the instruction for opening the door, receiving an instruction for confirming the receiving of the opening dooraction and a message for updating a database. According to the invention the method and system have the advantages that safety devices are conveniently arranged, the cost is low, the maintenance in the later period is easy and safety information can be reported in real time.

Description

technical field [0001] The invention relates to the field of ZigBee safety control, in particular to a ZigBee gateway-based distributed safety control method and control system for a building. Background technique [0002] The underlying technology of ZigBee is based on IEEE 802.15.4, that is, its physical layer and media access control layer directly use the definition of IEEE 802.15.4. During the use of Bluetooth technology, people found that although Bluetooth technology has many advantages, there are still many defects. For the fields of industry, home automation control and industrial telemetry and remote control, Bluetooth technology is too complicated, with high power consumption, short distance, and too small a network scale. In industrial automation, the demand for wireless data communication is becoming stronger and stronger, and for industrial sites, this wireless transmission must be highly reliable and resistant to various electromagnetic interferences in indus...

Problems solved by technology

[0003] Due to the high density of people in traditional buildings, to ensure safety, it is necessary to install a series of safety equipment to ensure that dangers are detected and dealt with in the first place, so as to avoid greater economic losses

However, traditional building security equipment is usually laid out in a wired way, which is not only troublesome in wiring, but also high in cost, and maintenance is even more troublesome in the later stage. Even the more advanced wireless sensors on the market still rely on WIFI with a relatively short transmission distance. For data transmission, once the building is powered off and the network is disconnected, the building's security equipment will not be able to report data and the security system will fail
