基于DS2438芯片的智能化火灾传感器的设计与应用

Design and Application of Intelligentized Fire Sensor Based on DS2438 Chip

基于DALLAS公司的电池系统监视芯片DS2438,利用其内部丰富的硬件资源,设计出一种集温度感应与烟雾感应于一体的智能化火灾传感器。由于DS2438采用了1-Wire标准协议进行通信,使得该智能化传感器能够无缝地连接到所有基于1-Wire通信的监控系统。与传统的感烟、感温传感器相比,采用DS2438作为内核的智能传感器具有体积小、功能多、布线简单的特点,更适合智能化监控系统的使用,具有广阔的应用前景和推广价值。

Based on battery system monitoring chip from DALLAS company, making using of abundant in- ternal hardware resources of this chip, a intelligentized fire sensor which collects temperature induction and smog induction data is designed. Because DS2438 adopts 1-Wire standard protocol in its communication mode, it makes intelligentized sensor can link to all monitoring systems based on 1-Wire protocol. This intelli-gentized sensor which adopts DS2438 for kernel has small volume, more functions and simpler layout suitable than traditional sensor of smog and temperature induction. So it is more suitable for use in intelligentized monitoring system, and would have wide application prospect.
