Design Of Remote Intelligent Agriculture Greenhouse Control System Based On Android Platform

China is a great country in agriculture,agricultural cultivation is also a low labor force of human labor,has lagged far behind other advanced agricultural countries,the urgent need to improve the development of agriculture,the first need to change is to replace the intelligence of manpower.In recent years,with the rapid development of global computer technology and wireless communication technology,the introduction of intelligent control concept,replacing manpower is not only the future development trend of agricultural control,all aspects of the development of intelligent control makes the efficiency greatly improved.The control system mainly to the indoor temperature,humidity,light and other parameters of the collection and the corresponding data processing,the controller summary parameters through the GPRS communication module to send data packets sent to the user's mobile phone.Users can not close the greenhouse,as long as even the remote cloud server Android platform mobile phone can monitor the greenhouse environment parameters and to the control of the greenhouse,you can achieve longrange greenhouse shutter system and exhaust system.This system greatly reduces the cost of data transmission,while reducing the labor force and improve the safety factor.This paper adopts the embedded system to form the hardware platform of the agricultural greenhouses.The main control unit selects STM32F103 as the core controller.The temperature and humidity sensor adopts DHT11,the light intensity sensor(BH1750FVI),the relay drive motor as the control circuit,the GPRS communication module and the remote cloud Server connected to the hardware system using modular design ideas,to its simple structure,easy maintenance.Software platform part,the next bit machine first transplanted uC / OS-II real-time operating system,the establishment of the acquisition and control and wirelesstransmission tasks,and then write remote client Android platform Android software.Cloud server as a data transfer,a great convenience to our data transmission,greatly reducing the delay of the system command,so that the control of the greenhouse is more convenient.Finally,the hardware and software of the control system are tested to meet the expected design requirements.
