Description
Technical field
The present invention relates to forest monitoring field, particularly relate to a kind of forest fire preventing monitor system based on ZigBee and WSN.
Background technology
Forest fire is the enemy that forest is the most dangerous, and be also the most fearful disaster of forestry, its can bring the most harmful to forest, has destructive consequence.Forest fire does not just burn forest in blocks, the animal in injury woods, but also reduces the updating ability of forest, causes the effect of the barren of soil and the water conservation of destruction forest, even cause ecologic environment out of trim.Although the science of the world today advances with rapid changepl. never-ending changes and improvements, the mankind, in uniform forest fire, but still not yet obtain considerable progress; So forest fire prevention and discovery have more realistic meaning than putting out.
1, forest fire not only can burn many trees to death, reduces the density of crop, destroys forest structure; Also cause technology simultaneously, substituted by the seeds of low value, shrubbery, weeds, reduce the value of forest.
2, because forest is burnt, cause forest land exposed, the effect losing forest water conservation and conserve water and soil, other disasteies such as waterlogging, arid, rubble flow, landslide, dust storm will be caused to occur.
3, by the forest of fire wound, growth decline, for a large amount of derivative of forest disease and pest provides favorable environment, accelerates the death of forest.After forest fire, impel forest environment to occur sharply to change, the forest ecologies such as weather, waters and soil are interfered, and out of trim, often needs decades or upper a century just can be restored.
4, forest fire can burn the various production facility in forest zone and buildings, threatens the villages and small towns near forest, jeopardizes the safety of forest zone people's lives and properties, and forest fire simultaneously can be burnt to death and drive away precious birds and beasts.Forest fire also can produce a large amount of smog, contaminated air environment when occurring.In addition, Forest Fires will consume a large amount of human and material resources and financial resources, affects industrial and agricultural production.Sometimes also cause personal injury, impact society stabilizes.
Current to mainly contain two kinds: one for forest monitoring method be utilize the artificial sample of portable instrument to monitor, and two is the comprehensive monitorings utilizing satellite remote sensing technology.The former to environmental parameter remote real time monitoring, particularly manually cannot be difficult to the hazardous location arrived, there is the problems such as monitoring range is limited, monitoring periods is long, labour intensity is large, specific aim is poor, data acquisition is slow.Though the latter can better solve above-mentioned deficiency, owing to there being the requirement of Distance geometry resolution, have that data fineness is not high, the not congruent shortcoming of parameter, only have an appearance profile information.
ZigBee is the low-power consumption LAN protocol based on IEEE802.15.4 standard.According to international standard regulation, ZigBee technology is the wireless communication technology of a kind of short distance, low-power consumption.This title (also known as ZigBee protocol) derives from the Eight characters dance of honeybee, due to honeybee (bee) by circle in the air and " drone " (zig) shake wing " dancing " and come to transmit pollen place azimuth information with companion, that is honeybee relies on such mode to constitute communication network in colony.The major advantage of ZigBee technology is as follows:
1. low-power consumption.Under low power consumption standby mode, 2 joints No. 5 dry cells can support 1 node work 6 ~ 24 months, even longer.
2. low cost.By significantly simplifying agreement (less than 1/10 of bluetooth), reduce the requirement to communication controler, by forecast analysis, with the 8 8-digit microcontroller measuring and calculating of 8051, Full Featured host node needs 32KB code, and subfunction node is few to 4KB code, and ZigBee exempts from agreement patent royalty.The price of every chip block is approximately 2 dollars.
3. low rate.ZigBee is operated in the speed of 20 ~ 250kbps, provides the raw data throughput of 250kbps (2.4GHz), 40kbps (915MHz) and 20kbps (868MHz) respectively, meets the application demand of lower rate transmissions data.
4. closely.Transmission range, generally between 10 ~ 100m, after increase emissive power, also rises to 1 ~ 3km.This refers to the distance between adjacent node.If by the relay of route and inter-node communication, transmission range can be farther.
5. short time-delay.The response speed of ZigBee is very fast, generally proceeds to duty from sleep and only needs 15ms, and node connection enters network only needs 30ms, saves electric energy further.Compare, bluetooth needs 3 ~ 10s, WiFi to need 3s.
6. high power capacity.ZigBee can adopt starlike, sheet and mesh network topology, manages some child nodes, maximum host node ALARA Principle 254 child nodes by a host node; Host node also by last layer network node control, can form at most the large net of 65000 nodes simultaneously.
7. high safety.ZigBee provides three level security patterns, comprise without security settings, use access control inventory (AccessControlList, ACL) prevent illegal acquisition number according to this and adopt Advanced Encryption Standard (AES128) symmetric cryptography, to determine its security attribute flexibly.
8. unlicensed band.Use industrial scientific medical (ISM) frequency range, 915MHz (U.S.), 868MHz (Europe), 2.4GHz (whole world).
Wireless sensor network (WirelessSensorNetworks, WSN) is a kind of distributed sensor, and its tip is can perception and the sensor checking the external world.Sensor in WSN wirelessly communicates, and therefore network settings are flexible, and device location can be changed at any time, can also carry out the connection of wired or wireless mode with internet.The multihop self-organizing network formed by communication.
