| Abstract: | 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 microcontroller 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. |
