The invention discloses a remote forest environment factor monitoring system, which is composed of multiple data acquisition nodes and a gateway node, wherein each data acquisition node comprises a solar power supply system, a soil temperature and humidity sensor circuit, an air temperature and humidity sensor circuit, a light intensity sensor, a signal conditioning circuit and a CC2530 chip circuit; and the gateway node comprises a solar power supply system, a GPRS module circuit, an MSP430F149 single chip microcomputer circuit, and a CC2530 chip circuit. Firstly, each data acquisition node acquires needed air temperature and humidity, light intensity and soil temperature and humidity for forest environment monitoring via the sensor circuits; then, based on a Zigbee protocol, data of each acquisition node are transmitted to the gateway node, and the gateway node wirelessly transmits the data of each acquisition node to a remote server via the GPRS. The remote forest environment factor monitoring system has the advantages that the monitoring range is large; configuration is flexible, power consumption is low, damage to the natural environment is little, the cost is low, and multipoint forest environment data can be monitored remotely and accurately in real time.
Description
Technical field [0001] The invention relates to the technical field of forest environment monitoring, in particular to a forest environment monitoring system capable of remote real-time monitoring of multiple points. Background technique [0002] As the basic industry of national production in our country, forestry occupies a pivotal position in the entire national economy. Monitoring the forest environment can provide long-term and reliable ecological environment data for the study of the interaction between the forest ecosystem and the environment. Since forest ecological environment monitoring points are usually distributed in relatively remote geographical locations, scattered and without power supply, traditional manual monitoring has low efficiency and high labor costs, and domestic forest environment monitoring instruments have single functions, large volumes, and high prices. and many other issues. Contents of the invention [0003] Aiming at the deficiencies in t...
