Problems solved by technology

[0015] The soil carbon flux data collection method of existing equipment is very single, and the obtained data cannot provide data support for wide-area, timing, and sampling analysis, let alone realize intelligent and diversified data collection operations
[0016] Moreover, the price of each existing equipment is as high as hundreds of thousands of yuan, which cannot meet the needs of intelligent network deployment for a large number of equipment in terms of cost.
Existing equipment consumes a lot of power, and the self-sustaining period of the equipment is too short, let alone solar energy, and it is impossible to realize the intelligent deployment of a large number of equipment

Abstract

The invention discloses a soil surface CO2 flux monitoring system based on a WSN (wireless sensor network). The monitoring system comprises a hardware system and a software system. The hardware system comprises a circuit device and a mechanical device. The circuit device comprises a TelosB module, a CO2 sensor measurement module, a display module, a main control circuit module and a photoelectric switch sensing module. The mechanical device comprises a solar energy charging panel, a top cover, a support medium cover, a measuring chamber base. The measuring chamber comprises an air chamber with at least one air valve. The software system comprises a central control system, an air chamber control system, a measurement control system, a data processing system and a network management system. The central control system controls the air chamber control system, the measurement control system, the data processing system and the network management system. After the air chamber control system detects that the air chamber is completely closed, the measurement control system is started. Through the data processing system, real-time CO2 concentration and measuring time are displayed on a display module. After one measurement is completed, the air chamber control system make the air chamber open, a display interface of the display module returns to an initial interface and waits a starting command of the next measurement. The data processing system sends measurement data to the network management system and receives an instruction from the network management system. A technology of the invention is suitable for the CO2 flux monitoring field in which automatic acquisition is needed and massive information needs to be automatically processed.

Description

technical field [0001] The present invention relates to a kind of soil surface CO 2 A flux, temperature, humidity and decibel monitoring system belongs to the technical field of atmospheric environment monitoring, in particular a forest environmental benefit monitoring system based on a wireless sensor network in a complex environment. Background technique [0002] Soil respiration reflects the ability of soil nutrient transformation and supply to a certain extent, and is an important biological indicator of soil quality and fertility and an indicator of soil health. Therefore, the more accurate measurement of carbon dioxide flux on the soil surface is of substantial and important significance for the accurate carbon accounting of terrestrial ecosystems and the implementation of the United Nations Framework Convention on Climate Change. In the existing technical field, there is no CO that can automatically collect and process massive amounts of information. 2 Flux monitori...
