Embodiment Construction

[0038] Below in conjunction with specific embodiment, the present invention is further described, and system of the present invention is applied in intelligent building, and the construction method of the monitoring and positioning system based on ZigBee distributed storage is:

[0039] 1) Arrange ZigBee reference nodes reasonably in the building to form a ZigBee wireless network. Authorized positioning nodes and intelligent network terminals enter the ZigBee wireless network range, automatically search and join the ZigBee wireless network, and communicate freely between nodes;

[0040] 2) Each reference node stores the map fragments of its area respectively, and the map fragment data is sent to one or more of the positioning node, intelligent network terminal or background host computer through the ZigBee wireless network.

[0041] like figure 1 As shown, a monitoring and positioning system based on ZigBee distributed storage includes reference nodes, positioning nodes, intel...

Abstract

The invention discloses a monitor positioning system and a method based on ZigBee distributed storage. The system comprises reference nodes, location nodes and an intelligent network terminal which communicate freely through a ZigBee wireless network, wherein the reference nodes are mounted at positions of a building respectively and used for storing map fragments of an area and sending radio waves; and when obtained authorized location nodes and the intelligent network terminal enter a network range, the obtained authorized location nodes and the intelligent network terminal can join the network and communicate with other nodes, the reference nodes can send the stored map fragments to the location nodes or the intelligent network terminal, and accordingly, the location nodes or the intelligent network terminal can obtain a local or full map of the building. According to the monitor positioning system and the method based on ZigBee distributed storage, ZeeBee and a distributed storage technology are combined, an ordinary intelligent building monitoring function is achieved, the ZigBee reference nodes are used as a distributed storage device to preserve the map fragments of the area, the reference nodes achieve redundant backup, and the safety and the robustness of the system are improved.

Description

technical field [0001] The invention belongs to the field of building monitoring and positioning, in particular to a monitoring and positioning system and method based on ZigBee distributed storage. Background technique [0002] With the development of economy and society, various high-rise buildings are constantly emerging, and the safety and monitoring problems of buildings are becoming more and more prominent, among which fire safety is the most important problem. In the event of a sudden fire in a building, obtaining the building map information and on-site environmental data information in a timely manner, knowing the information of the target to be rescued, and taking appropriate rescue methods can save unnecessary loss of life and property. At the same time, the life safety of firefighters has surpassed the value of their personal lives, and their safety is of great significance to improving rescue efficiency. However, in the current fire rescue system, after a fire ...
