Abstract

The invention discloses a forest surface moisture content monitoring system based on LoRa wireless ad hoc network, and belongs to the field of forest monitoring and moisture content prediction. The forest surface moisture content monitoring system based on LoRa wireless ad hoc network covers two systems and one communication mode, namely, a sensor data acquisition system, a terminal display systemand a LoRa data transmission communication mode. Meanwhile, an ad hoc network is formed in communication mode and fully covers forest monitoring. The sensor data acquisition system adopts a high-precision environmental sensor; and the surface litter moisture content of a forest is predicted by measuring the temperature, humidity, air speed and air pressure of the forest. The applied technologiescomprise an STM32 single chip microcomputer system, LoRa data transmission communication configuration and networking, a display terminal design and the like.

Description

technical field [0001] The patent of the invention belongs to the field of real-time monitoring of the moisture content of forest surface combustibles, and mainly relates to the collection of forest surface meteorological factors and the monitoring of the moisture content of surface combustibles, which can be used to prevent or timely discover fire hazards in forests and make early warnings. Background technique [0002] Forest fire is a natural disaster that is sudden, destructive, and difficult to deal with. In order to prevent the occurrence of deep forest fires, we can understand the fire hazards in the forest by detecting forest meteorological factors. [0003] The conditions for forest fire to occur are combustibles, fire dangerous weather and fire source. The present invention judges whether it becomes combustible by monitoring the forest environment factors, so as to give the fire danger prediction level. [0004] Based on high-precision environmental sensors and Lo...
