摘要
温度对工农业生产和国防事业均有不同程度的影响,为了对温度进行适时远程监控,设计了这套系统。系统采用AT89S51系列单片机与Dallas单线数字温度传感器DS18B20采集现场温度数据,NiosⅡ作为上位机,借助互联网,实现对温度进行远程监控。与传统温度监控系统相比采用了嵌入式的服务器,减小了硬件体积,提高了实时性。同时给出了该系统的硬件原理图和程序流程图。
The temperature has the varying degree influence to the industry and agriculture production and the national defense enterprise, to carry on to the temperature at the right moment monitors, computer temperature remote supervision is designed. In this system,a AT89C51 single chip is applied as a control unit and a Dallas chip DS18B20 is applied too as a digital temperature sensor. System uses soft IP processor Nios Ⅱ to configure CPU at Cyclone series chip used for the upper subsystem.. With Internet, it achieves the temperature remote monitoring. The hardware volume,improved real - time with embedded Web server are reduced. This article gives this system＇s hardware schematic diagram and the program flow diagram.
