摘　　要：以LonWorks现场总线技术为基础,以新型单总线数字温度传感器DS18B20为测温元件,提出了一套新型的分布式测温系统。整个测温系统由一台上位机和多个Host-Based结构的智能节点组成,其中智能节点采用单片机AT89C51为主处理器、神经元芯片TMPN3120为从处理器、FTT-10A为收发器。系统中单片机将采集来的温度数据传送给神经元芯片,然后数据经由收发器通过LON网络传输到上位机。该系统具有结构简单、测量精度高、抗干扰能力强等特点,具有广泛的应用前景。Introduces a new kind of temperature measurement distributed system based on LonWorks field bus technology. Its temperature measurement apparatus adopts DS18B20 which is a new single bus digital temperature sensor.The whole system is made up of a main computer and many Host - Based intelligent nodes. Each intelligent node takes on microcontroller AT89C51 as host processor, Neuron chip TMPN3120 as slave processor and FFT - 10A as transceiver. The microcontroller passes temperature data collected to the Neuron chip and the transceiver transmits data which are outputted by the Neuron chip to the main computer through LON network. The system is charactered with simple structure, high measurement precision and great anti - interference capability and its application prospects are wide.
