基于Android平臺的遠程智能農(nóng)業(yè)大棚控制系統(tǒng)設(shè)計
[Abstract]:China is the largest agricultural country in the world, and the cultivation of agriculture also adopts the method of low labor force, which has lagged far behind other advanced agricultural countries, and the development of agriculture urgently needs to be improved. The first thing to change is to replace manpower with intelligence. In recent years, with the rapid development of global computer technology and wireless communication technology, the concept of intelligent control has been introduced in China, replacing manpower is not only the development trend of agricultural control in the future. The use of intelligent control in all aspects of the development greatly improves the efficiency. The control system mainly realizes the collection and data processing of indoor temperature, humidity, illumination and other parameters. After the controller summarizes the parameters, the data is packaged and sent to the user's mobile phone through the GPRS communication module. Users can monitor the environmental parameters of greenhouse and control the greenhouse without using the Android platform mobile phone with remote cloud server, which can realize the rolling curtain system and exhaust air system of the greenhouse. The system greatly reduces the cost of data transmission, reduces the labor force and improves the safety factor. In this paper, the hardware platform of agricultural shed is constructed with embedded system scheme. The main control unit selects STM32F103 as the core controller, the temperature and humidity sensor adopts DHT11, light intensity sensor (BH1750FVI), and the relay drives motor as control circuit. The GPRS communication module is connected with the remote cloud server. The hardware system adopts the modular design idea to make its structure simple and easy to maintain. In the part of software platform, the uC/OS-II real-time operating system is transplanted to the lower computer, the task of acquisition and control and wireless transmission is established, and then the Android software of remote client Android platform is written. As data transfer, cloud server greatly facilitates our data transmission, greatly reduces the delay of system commands, and makes the control shed more convenient. Finally, the hardware and software of the control system are tested to meet the expected design requirements.
