Research on 1-Wire Bus Temperature Monitoring System
Based on 1-Wire bus technology, the 1-Wire bus temperature monitoring MicroLan was designed through using computer serial communication port, protocol transform chip DS2480 and 1-Wire bus digital temperature sensor DS18B20. The structure, character, ROM command, function command of DS18B20 and operating principle of DS2480B were analyzed. Consequently, the interface circuit between 1-Wrie bus and COM port is provided. At the same time, operating interface of 1-Wire bus temperature monitoring MicroLan was well designed by using the DLLs and API functions provided in the TMEX SKD by Dallas Corporation and taking DELPHI as developing tool. Finally, the existing problems and improving methods was put forward.
