Design And Experiment Of Greenhouse Environment Monitoring System

Greenhouse internal environmental factors such as humidity,temperature,light and so on are closely linked with plant yield,the appropriate environment can improve the yield of plants to increase the economic benefits of greenhouse cultivation.At present,the number of small and medium plastic greenhouse huts in our country are more than the others,but the internal working conditions are poor.These greenhouses still use manual measurement tools to measure environmental parameters or experience to judge,and manually control the relevant equipment to adjust the greenhouse internal environment,this is not only labor is large but prone to greater error.It is a high temperature,high humidity environment inside the greenhouse,its internal space electric field equipment,light equipment,etc.will have an impact on human health.Therefore,When the greenhouse environment is abnormal with the alarm prompting,it is necessary to use the greenhouse greenhouse environmental monitoring system to complete the detection of the internal environment of the greenhouse,control and manage the internal equipment of the greenhouse,so as to reduce the labor of workers and protect the health of the human body.This paper analyzes the environment of small and medium-sized greenhouse under the influence of space electric field.And the greenhouse environmental inspection system is designed,according to the characteristics of these greenhouse environment.The detection system is used inside the small and medium-sized greenhouse and carry out the detection of temperature,humidity,ammonia,ozone and other environmental factors,control the environment inside the greenhouse according to the user’s settings.When the greenhouse gas outside the safe range beyond the system,the alarm will prompt.And when someone enters the greenhouse,the system will cut off the power of dangerous equipment to protect human health.The system will improve the ability to work in a high-voltage electric field environment by taking some anti-jamming measures.The important part of the system is detachably connected and the external expansion interface is reserved on the main circuit board for easy installation,maintenance and external expansion.The system follows the principle of economic utility when select part of the hardware,this reduces the production cost to a certain extent.After the system is finished,the working property and anti-jamming ability of the system are tested respectively,and the design of the system was modified according to the results of test.
