Forest fire monitoring device and monitoring method based on wireless sensor network

Abstract

The invention discloses a forest fire prevention monitoring device based on a wireless sensor network, which includes a plurality of clusters, a convergence node, a communication network and a remote monitoring center; the clusters include a cluster head node and a monitoring node, and the monitoring nodes are Communicate with each other and transmit the collected forest environment information to the cluster head node. The data information of the cluster head node will be transmitted to the aggregation node through the communication network for fusion, and finally transmitted to the monitoring center; the monitoring center receives the data and synchronizes the forest fire prevention The environmental information and location information of the monitoring area will immediately send out an alarm when the sensor detects that the smoke concentration and air temperature and humidity exceed the preset value; the wireless sensor network combined with the directional antenna and the omnidirectional antenna adopted in the present invention can automatically Composing a forest fire prevention monitoring system reduces the difficulty of artificially laying out fixed monitoring points, and is more suitable for virgin forests where there are few people and the terrain is extremely complex.

Description

technical field [0001] The invention belongs to the technical field of forest fire prevention, and in particular relates to a forest fire prevention monitoring device and monitoring method based on a wireless sensor network. Background technique [0002] Forest is an irreplaceable natural resource on the earth, and it occupies an important position in the survival and development of all human beings. If a fire breaks out, it will not only seriously affect forestry construction and ecological environment, but also affect a country's economic construction and development and long-term social security, endangering human life and property safety, and is not conducive to the people's living and working in peace and contentment and the long-term stability of the country. The occurrence of forest fires has the characteristics of high suddenness, rapid spread, and difficulty in fighting. Once a dangerous situation occurs, it is difficult for us to control it. At the same time, the f...

Problems solved by technology

However, because the forest covers a huge area and the terrain is complex, it is extremely inconvenient to bury monitoring nodes

For the positioning of monitoring nodes, the traditional monitoring system is the GPS satellite positioning system, and the monitoring node needs to determine its location information through the signal of the GPS satellite positioning system. This method has relatively long transmission time and high cost. The terrain in the upper forest area is complex and diverse, with many trees, which are prone to problems such as terminal hiding, multi-path fading, and shadow effects, which may easily lead to inaccurate node positioning.
