Design Of Water Environment Real-time Monitoring System For The Trees

Recently,the application of precision irrigation in China's agriculture and forestry has become more and more popular.With the rapid development of information technology and sensor technology,the detection and control system for forestry information intelligence has been improved.Comprehensive measurement of soil moisture,stem moisture and air humidity.The study and design of a kind of living standing wood physiological water environment monitoring and measuring device with strong real-time performance,wide application range and high precision.The main contents and results of this paper are as follows:1.Introduction of the precision water-saving irrigation control laboratory of Beijing Forestry University,which freely developed soil moisture sensors,stem water sensors,and air temperature and humidity sensors.The system has been designed according to the project requirements of Inner Mongolia Hesheng Ecological Technology Research Institute Co.,Ltd.2.This article has completed the hardware design of the water environment real-time monitoring system including signal acquisition module,AD conversion module,clock module,storage module,data sending module.Besides,hardware compatibility design between modules has been performed,especially the power supply compatibility was considered.3.This article has completed the software design of the water environment real-time monitoring system adopting the C language.This system realizes the acquisition of three parameters of soil water environment by data acquisition system and the design of each module including initialization module,clock module,data storage module,etc.4.This article has completed the collection of experimental data,and the website displays the three parameters of the data's water environment.This paper compares the data to find the correlation between the three parameters of the water environment and the physiological parameters of the trees providing data support for future research experiments.In general,this paper designed a real-time environment monitoring system.The system completed the company's various project requirements.The real-time monitoring system for water environment is currently running steadily,and the data was continuously uploaded in real time.The system can adapt to various weather conditions and collection environment,and uses 220V mains and solar panels to supply power cooperatively.According to different experimental environments of the project,two kinds of communication methods(Wireless GPRS or Compass communication)are used to upload data.So far,the system has collected a large amount of data for experimental use,and the water environment monitoring system has reached the design requirements.
