摘要
给出了含有IP节点的离子感烟探测器的硬件结构、原理和软件设计方法。该探测器以89C52单片机为核心,由MC14467获取离子感烟传感器镅241(Am241)检测的烟雾报警信号;并通过移植uIP0.9协议栈,实现了探测器的Internet网络接入功能。该探测器既可以独立运行,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。
Introduced the hardware circuits, theory and software method of Ion Sensing Smoke Detector.89C52 MCU is its core. The smoke signal detected by Am^241 can obtain by MC14467. 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 intemet in different place.
