Abstract
With the development and application of modern greenhouse technology and the huge demand of anti-season vegetables,greenhouse plays an important role in the cultivation of anti-season vegetables,which is one of the key issues of relevant technical personnel.China′s vegetable greenhouses are still in the early stages of development,while the foreign vegetable greenhouses,although tend to improve,but its economy and adaptability are open to question.A modern regetable greenhouse automatic control system based on the environment of our coutry,whose price is close to the people,the operation is simple and the funciton is stable,needs to be created.Based on the analysis of the characteristics of the automatic control system of vegetable greenhouses,this paper designed the PID automatic control system of vegetable greenhouse temperature based on PLC.PLC real-time detection data of the variables surveyed by various sensing devices,and adjust the temperature in the greenhouse by comparing with the set parameters.The simulation test of the system shows that the greenhouse temperature automatic control system has basically reached the control target,the control is relatively stable and reliable,with high economy.关键词
