Fire alarming method based on wireless mesh network

Abstract

The invention provides a fire alarming method based on a wireless mesh network. The method comprises the following steps of arranging a plurality of sensor mesh nodes in an area which requires monitoring, wherein each sensor mesh node is connected with a backbone network and interacts with a central server arranged at a monitoring center through the backbone network; using each sensor mesh node asa terminal node and a routing node; pre-assigning a unique identity ID to each sensor mesh node in the network; performing real-time acquisition on on the light strength and temperature data at a position by the sensor mesh node, packaging the identity ID and the acquired data, and uploading to a central server through the backbone network; determining whether each position is abnormal by the central server according to the received data, and if the abnormity is determined, generating fire alarm information and transmitting to an upper computer. The fire alarming method can acquire the abnormity occurring position in time, thereby eliminating risk factors in time. A wired connection between the sensor nodes is prevented, and fire spreading along the wire caused by wire connection is prevented.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a fire alarm method based on a wireless mesh network. Background technique [0002] The existing fire monitoring methods mostly use wired network to transmit data, but the wired network wiring is complex, and line maintenance is also very difficult, and due to factors such as the length of the line and transmission distance, the layout position of each node device in the wired network is restricted, resulting in There are monitoring dead angles, which cannot meet the monitoring requirements very well. Especially for public places with relatively large venues, such as movie theaters, office buildings, etc., once a fire breaks out in an unmonitored location, it is easy to cause the fire situation to not be contained in time, and in severe cases, it will endanger personal safety. However, the method of wiring monitoring is used to monitor, and it is easy to cause joint effects ...

[0002] The existing fire monitoring methods mostly use wired network to transmit data, but the wired network wiring is complex, and line maintenance is also very difficult, and due to factors such as the length of the line and transmission distance, the layout position of each node device in the wired network is restricted, resulting in There are monitoring dead angles, which cannot meet the monitoring requirements very well

Especially for public places with relatively large venues, such as movie theaters, office buildings, etc., once a fire breaks out in an unmonitored location, it is easy to cause the fire situation to not be contained in time, and in severe cases, it will endanger personal safety

However, the method of wiring monitoring is used to monitor, and it is easy to cause joint effects due to wired line connections, which will expand the fire area.
