【摘要】：我国是世界上第一农业大国,农业种植还采用劳动力低下的人力劳作方式,已经远远落后于其他先进的农业国,农业的发展迫切需要改善,首先需要改变的就是以智能化来代替人力。近些年来,随着全球计算机技术与无线通信技术的快速发展,国内引进了智能控制概念,取代人力不仅是未来农业控制的发展趋势,各方面的发展采用智能控制使得效率极大的提高。本控制系统主要实现对室内的温度、湿度、光照等参数的采集与对应的数据处理,控制器汇总参数后通过GPRS通信模块将数据打包发送到用户手机。用户可以不用在温室附近,只需连有远程云服务器的Android平台手机即可监测温室内环境参数并加以该控制大棚,即可实现远程对大棚的卷帘系统与排风系统。此系统大大降低了数据传输成本,同时降低了劳动力并提高了安全系数。本文采用嵌入式系统方案组建农业大棚的硬件平台,主控单元选STM32F103为核心控制器,温湿度传感器采用DHT11,光照强度传感器为(BH1750FVI),继电器驱动电机为控制电路、GPRS通信模块与远程云服务器相连,硬件系统采用模块化设计思想,使其结构简明,维护方便。软件平台部分,下位机首先移植了uC/OS-II实时操作系统,建立了采集与控制及无线传输任务,然后编写远程客户端Android平台安卓软件。云服务器作为数据中转,极大的方便了我们的数据传输,大大降低了系统的命令的延时,使控制大棚更为方便。文章最后通过对控制系统的硬件与软件进行测试,达到了预期的设计要求。
[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.
