Multi-point Remote Monitoring System And Monitoring Point Optimization For Rice Breeding Greenhouse Environment

Under the background of the continuous improvement of agricultural technology in our country,the agricultural monitoring system is relatively mature,but as the demand of farmers increases,the technical requirements for monitoring agricultural production and facilities environment are also increasing.This study developed and designed a multi-point remote monitoring system for the environment characteristics of northern rice breeding greenhouses.Firstly,the design scheme of multi-point temperature and humidity data collection equipment in rice breeding greenhouses was studied.The acquisition system was based on STC15 series single-chip microcomputer with multi-channel and high-speed A/D conversion.The high-precision composite sensor and low-power consumption broadcast monitoring function were selected,with wireless communication equipment,the system can operate stably for a long period of time,and multiple data transmissions are not lost.Acquisition system in field experiment in actual greenhouse,use the acquisition of relative more environmental information analysis inside the greenhouse temperature and humidity change rule and spatial distribution characteristics.Using Matter-element analysis combined with cluster analysis method of optimize the inside the greenhouse environment monitoring points,the clustering result is consistent with the spatial distribution of multi-point temperature and humidity,divided into five groups were combined with the distribution of overall in the greenhouses to select the appropriate monitoring,the monitoring point is optimized with the original more comparison,the results show that the method in the stationing of seedlings cultivation temperature and humidity inside the greenhouse environment optimization is feasible.Finally,this study aimed at the optimized monitoring points,the use of the advantages of the LabVIEW software development is simple and steady operation of PC monitoring platform design,system PC inside the greenhouse temperature and humidity data real-time acquisition shows that can be saved to collect data and obtaining and management functions,such as curve change and on the basis of the LabVIEW has its own Web remote release function will set up this system available for users inside and outside network remote monitoring at any time.Debugging and running,the system displays the human-computer interaction friendly interface,stable and reliable running.
