Building state monitoring and escape guiding system and building state monitoring and escape guiding method

Abstract

A building state monitoring and escape guiding system comprises a wireless node, a local base station and a remote monitoring center, wherein the wireless node comprises wireless sensing nodes, wireless lamplight indicating nodes and routing nodes, and the local base station comprises a front-end wireless interface and a local monitoring center. The wireless node is arranged in a monitoring area, communication among the wireless sensing nodes, the wireless lamplight indicating nodes and the routing nodes as well as among the routing nodes and the front end of the local base station is achieved through a tree-shaped networked ZigBee multi-hop routing protocol, the wireless sensing nodes transfer building environment information and building structural information in the monitoring area to the front end of the local base station through a wireless channel, the front end of the local base station forwards the information to the base station monitoring center through a serial port, command information of the base station monitoring center is broadcast through the front-end wireless interface, and the remote monitoring center accesses to the local base station monitoring center through a local area network. The building state monitoring and escape guiding system is in communicated connection with a wireless network so as to form a small server to share disaster information with the outside through the Internet.

Description

technical field [0001] The invention relates to a monitoring technology using a wireless sensor network, in particular to a building state monitoring and escape guidance system and method thereof, belonging to the technical field of sensor networks. Background technique [0002] With the rapid development of my country's economy, large-scale buildings continue to increase, and the indoor structure of buildings is complex. Under normal conditions, ordinary people need to use various signs to find the target location (such as toilets, elevators, etc.). When disasters such as structural damage occur, people's ability to judge is reduced due to panic or fear. If there is no reasonable escape guidance system, unnecessary casualties will obviously be caused. [0003] Building status monitoring includes building environmental parameter monitoring and building structure deformation monitoring. Building internal environmental parameter monitoring includes indoor temperature, humidity,...

AI Technical Summary

Problems solved by technology

[0004] At present, the emergency evacuation system technology in buildings has been developed relatively maturely, but they are all aimed at fire scenarios. If an earthquake occurs, or the building tilts or even collapses due to uneven settlement, the evacuation system in the building will hardly work.

Although both are guidelines for escape and evacuation, the systems for earthquakes, collapses and other building structure deformation disasters and fire lights are very different in different situations
