长春理工大学毕业设计 摘 要 系统以AT89S52单片机为控制核心，以太网模块作为接口，温度控制系统作为被控对象，并采用单线数字温度传感器DS18B20采集现场温度数据而设计的远程温度控制系统，实现了基于以太网的远程温度监控。该系统具有结构新颖、电路简单和控制方便等优点。并可根据需要设置控制温度的上、下限，系统具有超过设置上、下限温度自动告警等功能。 本文阐述了系统的硬件和软件的具体实现和所用到的关键技术。介绍了一种用ZNE-100T以太网转串口模块实现AT89S52单片机与以太网通信的方法。开发了ZNE-100T的结构与用法及与AT89552的硬件连接方法和软件设计。 关键词: 远程监控 以太网 ZNE-100T 单片机 ABSTRACT In this paper,employed AT89S52 MCU as the core component,Ethernet module as the interface and temperature control system as the object,a chip DS18B20 is applied as a digital temperature sensor to realize remote temperaturemonitoring based on Ethernet.The system possess of many excellences,including its novel structure,simple circuit and expedient control.The upper and lower limit value of the temperature controlled by this system can be set discretionarily and an alarm will be given by system if the temperature exceeds the limits. The thesis tells us details concrete realization and the key technology used in hardware and software of system.In this paper,a method of implementing Ethernet communications of AT89S52 using Ethernet of serial interface ZNE-1OOT is recommended,mainly describing thes trueture and usage of the ZNE-100T and eonnection method with AT89S51 and software design.
