【摘要】 本文介绍了单线制数字式温度传感器DS1820的测温原理、测温步骤以及工程应用中的几个实际问题,并结合LonWorks现场总线节点给出一个测量单点温度的例子,然后阐明了测量多点温度的方法。此实例可进一步推广到适合传感器温度量程的其它温度控制系统中去。更多还原

【Abstract】 A method of single-point temperature measurement using the device of DS1820- 1-Wire digital thermometer, is introduced in this article. An example based on the control system of Lon Works field bus is also given. And a method for multidrop application follows. The example can be popularized in other appropriate temperature control systems.更多还原
