Embodiment Construction

[0032] Concrete work process of the present invention is:

[0033] First, the coordinator builds a network.

[0034] Secondly, the router or collection terminal joins the network through energy scanning of the channel, after joining the network

[0035] Then it can work, the routing node is responsible for managing other collection terminals or routing nodes to join the routing work, the terminal node is responsible for collecting environmental information, and monitoring the occurrence of fire sources, all terminal nodes are added to the network in this way, and finally Form a large wireless network sensor network.

[0036] Again, after the terminal node joins successfully, it will collect data and pass the routing function of the routing node and other

[0037] The forwarding function of the node will finally transfer the data to the sink node for corresponding processing.

[0038] Finally, after the sink node receives the information sent by the terminal node, it identif...

Abstract

The invention discloses a forest fire positioning and alarming system based on a wireless sensor network, which relates to the field of wireless transmission and fire monitoring. The forest fire positioning and alarming system consists of a terminal node and a convergence node, wherein the terminal node consists of a coordinator node, a router node and an acquisition node. The invention further discloses a forest fire monitoring, finding, positioning and alarming method based on the wireless sensor network and a terminal node arrangement method. A sensor of the terminal node is used for monitoring a forest environment and a fire extinguishing point. The system has the advantages that: the wireless sensor network is applied to forest fire prevention, an origin of fire is positioned according to the characteristic of any terminal node in the wireless sensor network, and all nodes in the entire network have monitoring and positioning functions. According to the advantages of zigbee and embedding, a fire positioning and alarming system with low cost, low power consumption and high interference resitance is established.

Description

technical field [0001] The invention relates to the fields of wireless transmission and fire monitoring, in particular to a forest fire positioning and alarm system based on a wireless sensor network. Background technique [0002] Wireless sensor network technology is a new technology in the 21st century. It is composed of a large number of cheap micro sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network through wireless communication. Wireless sensor network is a combination of sensor technology, embedded computing technology, wireless communication technology, and distributed information processing technology. Its main characteristics are low power consumption, low cost, distributed and self-organizing. In the whole wireless sensor network, data acquisition, processing and wireless transmission are its core functions. [0003] my country's wireless sensor network technology started relatively late in China, and is currently mainly in...
