基于ulP的温湿度监控系统

Temperature and Humidity Monitor System Based on uIP

针对现有温湿度监控系统在功耗、通信及抗干扰方面存在的缺陷,文中给出了含有IP节点的温湿度监控系统的硬件结构、原理和软件设计方法。探测器以89C52单片机为核心,通过频率法采集温湿度,并通过移植uIP0.9协议栈,实现了控制器的Internet网络接入功能。该控制器既可以独立运行,又可以通过IP节点实现联网,且允许用户异地访问,具有较大的灵活性。

This paper introduces a new type of temperature and humidity monitor system based on the analysis of the advantages and the disadvantages of existing systems, gives the hardware circuits, theory and software method of the controller. 89C52 MCU is its core, and uses V/F （Voltage/Frequency） circuit to gain analog. The IP node is realized through transplanted uIP0.9 protocol stack. The detector can run independently, also it can form network via IP node, and it allows user obtain information through Internet in different place.
