摘　　要：本文基于LonWorks现场总线技术,采用新型单总线数字温度传感器DS18B20提出了一种新型的分布式测温系统。系统由一台上位机和多个智能节点组成,智能节点采用单片机MSP430F149为主处理器,神经元芯片3150为从处理器。用单片机进行温度数据采集,输出数据经收发器通过LON网络传给上位机,实现了对温度的实时、准确及自动检测。The paper introduced a new kind of temperature measurement distributed system based on LonWorks field bus technology.DS18B20 is adopted in the system which is a new single bus digital temperature sensor. The whole system is made up of a main computer and many intelligent nodes. Each intelligent node takes on microcontrolter MSP430F149 as host processor and Neuron chip 3150 as slave processor. The microcontroller fulfils temperature data acquisition and the Neuron chip and transceiver pass data which are outputted by the microcontroller to the main computer through LON network. Real-time, accurate and automatic temperature detection is realized in the system.
