远程温湿度监测报警系统的设计与实现

Design and implementation of remote monitoring and detecting system for temperature and humidity

随着嵌入式技术和通信技术的发展,集散控制系统在各大领域得到了广泛的应用。现介绍了一种基于CAN总线和以太网接口的远程温湿度监测报警系统;详细描述了系统的总体组成、硬件结构和软件设计。试验结果表明,该系统不仅能实时监测局域网内的温湿度,还能通过全球移动通讯系统和互联网实现远程报警和数据上传,很好地满足了药品批发和零售商对仓库温湿度监控要求。

With the development of embedded technology and communication technology,the distributed control system has been widely used in every field.This paper introduces a remote monitoring and detecting system which based on Controller Area Network（CAN） and Ethernet interface.It also describes overall structure of the system,the hardware composition and the software design.The practical application indicates that,this system not only can be real-time monitoring for the temperature and humidity in local area network,but also can realize remote alarm and data upload through the global system for mobile communication（GSM） and internet.So the drug wholesaler and the retailer＇s monitoring demand can be realized well.
