摘要
介绍了数字式温度传感器DS18B20的工作特点与工作原理,利用DS18B20的单线总线数字输出的特点和单片机技术,给出了一种基于DS18B20构成的单线多点滑油温度监测系统的硬件结构和软件流程,测试结果表明该系统能够有效地监测滑油温度,具有操作方便、接口简单、成本低、性能可靠等优点。
the characteristics and working principle of digital sensor DS18B20 was introduced in this paper. By making use of the advantage of the characteristics of 1-wire digital output of DS18B20 and single chip microcomputer （SCM） technique, an monitoring system of for lubricant multi-temperal-ure based on DS18B20 is proposed, and the structure and software flow diagram of the system are given also, test results show that the system can monitor effectively lubricant temperature, it has characteristics of convenient manipulation, simple interface, low cost, credible performance etc.
