【摘要】：随着经济的发展,物联网技术也得到了快速的发展,智能厨房系统在人们的生活中得到了越来越多的应用。本文从智能厨房研究的背景意义及其国内外发展现状等方面做了简单叙述,并对课题的创新点做了阐述,简单的介绍了物联网技术,对物联网技术的各层功能做了分析。对比研究了多种无线传输技术,根据它们的特点最终确定了以ZigBee无线传输技术作为厨房内传感器网络的无线组网技术。对ZigBee技术的各层功能以及协议标准做了分析介绍。对系统的整体功能进行了总体设计,讲述了系统实现的各个功能,确定了采用星型网络作为ZigBee无线组网方式的拓扑结构。对家居网关进行了硬件及软件的设计,采用STM32F407芯片作为家居网关的主芯片,完成了家居网关外围电路的设计。采用CAN总线方式与协调器进行通信,采用Wi-Fi方式进行与外网的连接,利用彩屏进行人机的交互。对ZigBee网络进行了软硬件的设计,采用CC2530芯片作为其网络协调器以及节点处的主控芯片。对节点处采集信息的各传感模块进行了软硬件设计,包括摄像头模块、无线红外测温模块、温湿度采集模块、热释电模块等。通过实验的方式检验了各功能的实现情况,在实验的过程中测试了各模块的性能,分析处理了调试过程中出现的各种问题。实验结果表明本系统能够实现预期的目的,通过远程终端实现了智能厨房对儿童的监控保护、智能厨房煤气灶的监控、智能厨房鼠类的检测、智能厨房储物柜内温、湿度的监测等功能,相对于传统的厨房系统,本文设计的基于物联网的智能厨房更具优势,不仅省去了繁琐的布线,智能化程度也越发的提高,厨房的安全性能有了可靠的保障,而且增加了对儿童的保护等功能。
[Abstract]:With the development of economy, the technology of Internet of things has also been developed rapidly. Intelligent kitchen system has been applied more and more in people's life. This paper briefly describes the background significance of intelligent kitchen research and its development status at home and abroad, and expounds the innovation of the subject. This paper briefly introduces the technology of Internet of things, and analyzes the functions of each layer of the technology of Internet of things. According to their characteristics, the wireless networking technology using ZigBee wireless transmission technology as the sensor network in the kitchen is finally determined. The functions of each layer of ZigBee technology and the protocol standard are analyzed and introduced. The overall design of the overall function of the system is given. The functions of the system are described, and the topology of ZigBee wireless network is determined by star network. The hardware and software of the home gateway are designed, and the STM32F407 chip is used as the main chip of the home gateway. The peripheral circuit of home gateway is designed. CAN bus is used to communicate with coordinator, Wi-Fi is used to connect with external network, and color screen is used for man-machine interaction. The hardware and software of ZigBee network are designed. The CC2530 chip is used as the network coordinator and the main control chip at the node. The hardware and software of the sensor module are designed, including the camera module, the wireless infrared temperature measurement module, the temperature and humidity acquisition module. The realization of each function is tested by experiment, and the performance of each module is tested in the process of experiment. The experimental results show that the system can achieve the desired purpose. The intelligent kitchen can monitor and protect children through remote terminal, and the intelligent kitchen gas stove can be monitored. Compared with the traditional kitchen system, the intelligent kitchen designed in this paper has more advantages than the traditional kitchen system, such as the detection of mice in the intelligent kitchen, the monitoring of temperature and humidity in the storage cabinet of the intelligent kitchen, and not only the elimination of the tedious wiring, but also the advantages of the intelligent kitchen which is designed based on the Internet of things. The degree of intelligence has been improved, the safety of kitchen has been guaranteed, and the function of child protection has been increased.
