【摘要】：随着信息技术的不断发展,现代农业正在逐步取代传统农业,信息技术在农业生产上的应用也越来越广泛,人工植物培养室(或人工植物培养箱)就是其中一个典型代表。人工植物培养室(或人工植物培养箱)一般都有监测温度、湿度、光照度、二氧化碳浓度、土壤酸碱度这几个环境变量的功能,一旦发现其内部环境达不到植物生长的要求,可以自动进行调节。在信息技术发展的浪潮中,嵌入式系统无疑是最令人瞩目的技术之一。嵌入式系统是针对特定用户和特定需求而开发的一种专用计算机系统,一般都具有软件硬件可裁剪、运行稳定、体积较小、功耗较低等特点,近年来已经被广泛地应用于网络通讯、实时监控、工业自动化、消费电子产品等多个领域。本文结合ARM和Linux,设计了一款基于嵌入式系统的智能型植物培养箱,该培养箱有采集和控制两大功能。采用三星的S3C2440作为主控CPU,搭载了SDRAM、NandFlash、USB模块、网卡、SD卡等构成嵌入式系统的硬件基础,并连接了用于实时采集箱内温度、湿度、光照度、二氧化碳浓度这四个环境参数的传感器,还设置了一款摄像头用于拍摄箱内的实时图片。由于要实现箱内环境的调节,因此硬件部分还包括对应的环境调节装置。软件方面主要分为系统底层软件设计和应用层软件设计两大模块,底层软件设计包括构建嵌入式Linux系统和编写(或者配置)必要的驱动程序;应用层软件主要用于实现核心的业务逻辑,进行数据的采集、存储、控制、显示等。
[Abstract]:With the continuous development of information technology, modern agriculture is gradually replacing traditional agriculture, and the application of information technology in agricultural production is becoming more and more extensive. The artificial plant culture room (or artificial plant incubator) is a typical example. The artificial plant culture room (or artificial plant incubator) generally has the monitoring temperature, the humidity, the light intensity, the carbon dioxide concentration, The function of the environmental variables of soil acidity and alkalinity can be adjusted automatically once it is found that its internal environment does not meet the requirements of plant growth. Embedded system is undoubtedly one of the most attractive technologies. Embedded system is a kind of special computer system developed for specific users and special needs. Generally, it has software and hardware tailor-made, stable operation and small volume. In recent years, it has been widely used in many fields, such as network communication, real-time monitoring, industrial automation, consumer electronics and so on. In this paper, an intelligent plant incubator based on embedded system is designed based on ARM and Linux. The incubator has two functions of acquisition and control. It uses Samsung's S3C2440 as the main control CPU, carries the USB module of SDRAMN and Flash, and the SD card of network card to form the hardware foundation of the embedded system, and connects it to collect the temperature, humidity and illuminance of the box in real time. The sensor for the four environmental parameters, carbon dioxide concentration, is also equipped with a camera to take real-time pictures of the box. Therefore, the hardware part also includes the corresponding environmental adjustment device. The software is mainly divided into two modules: the software design of the bottom layer of the system and the software design of the application layer. The underlying software design includes building embedded Linux system and writing (or configuring) necessary drivers, and application layer software is mainly used to implement core business logic, data acquisition, storage, control, display and so on.
