Design And Implementation Of Environmental Monitoring System In Modern Agriculture Greenhouse

In recent years,as agricultural infrastructure agricultural greenhouse grew in popularity,along with the rapid development of agricultural greenhouse technology,how to carry out the scientific and efficient management of agricultural greenhouse is particularly important,which includes the greenhouse crop growth environment monitoring.It is well known that environmental factors are very important to the growth of crops.How to monitor the environment timely and effectively in the agricultural greenhouse has become an important part of the agricultural modernization.People also focus more and more on this issue.In the traditional agricultural greenhouse technology is mainly artificial placed a thermometer device,followed by artificial read these devices collected data to determine changes in agricultural greenhouse environment,and on the basis of the greenhouse environment management and improvement.Artificial monitoring and management method for greenhouse environment to master and improve the crop growth environment,but rely on the artificial way of greenhouse environmental monitoring and management,on the one hand difficult to achieve real-time monitoring of greenhouse environment,make to the greenhouse environment monitoring and response with a lag;on the other hand,frequent data reading,recording and feedback process greatly increased the workload of greenhouse managers,monitoring and management efficiency,is not conducive to the management and improvement of shed environment.With the development of science and technology,the continuous improvement of the degree of agricultural modernization,automatic control more and more is applied in agricultural greenhouse environmental monitoring and management process,to achieve the manual management to automatic,intelligent management of change.In this paper,the design of modern agriculture greenhouse environmental monitoring system,through the front end of the air temperature and humidity,soil moisture,light intensity sensor to collect greenhouse crop growth related environmental data,using based on ZigBee wireless sensor network technology to collect environmental data into effective real-time acquisition and transmission line,finally through the RS232 serial port line will collect data is uploaded to the host computer.In the PC monitor system,manual input of crop growth model(crop growth of basic environmental parameters)and collected crop growth information environment,if the environment is unfavorable to crop growth is warning,greenhouse management personnel according to the alert using greenhouse agriculture in agricultural facilities valve(such as air conditioning,wind machine,rolling,etc.),agricultural greenhouse environment parameter control,and ultimately achieve the real-time monitoring data of greenhouse crops growth environment for the purpose of timely management and improve compared to the all.Real-time monitoring of the environment can make management personnel in a timely and comprehensive understanding of the environmental parameters in greenhouse,for data analysis after the first time to make a response to lay the foundation,to production of high quality,high requirements provide security,to provide a constant,optimum growth environment for the growth of crops,to adjust the growth cycle,improve product quality,increase the output of agricultural products,improve the economic benefits.
