基于单片机的仓库通风控制系统的设计

湖南理工学院毕业设计（论文）AbstractIn recent years,with the continuous development of society,the warehouse automaticventilation control system has been widely used for the safe storage of articles.Thewarehouse ventilation system is capable of detecting the temperature of the current warehouse.And start the fan to reduce the temperature according to the actual temperature,turn off thefan when the temperature is lowered,and stop the alarm.As far as the current development isconcerned,the warehouse automatic ventilation control system will inevitably become anindispensable part of the company's cargo management.This paper designs a vegetable greenhouse thermostatic control system based onATmegal28 single-chip microcomputer.By comparing the temperature in the warehousecollected by the temperature sensor with the set temperature threshold,the temperature isautomatically controlled.The keyboard module can adjust the threshold temperature and thetemperature in the warehouse can pass.The digital tube display module is displayed.Aftertesting,the design meets the expected requirements,and the warehouse temperature can becontrolled within the set range,which has a good auxiliary effect on the storage of warehousegoods.The system designed in this paper consists of six major components:main controlmodule,sensor module,display module and alarm module.Through the collection andanalysis of the internal temperature of the warehouse,the purpose of ventilation cooling isachieved.This design strives to be accurate,practical and easy to operate.Keywords:ventilation;sensor;DS18B20;single-chip microcomputer
