Design of Temperature Monitor Device for DC Source Based on 1-Wire Bus

The structure of X6000 DC source system is introduced. A temperature monitor device for its storage pile based on 1-wire bus is designed. Its central processing unit is single chip microcomputer 80296SA in the monitor unit of this DC source. The DS1822 chip, a kind of digital thermometer chip based on 1-wire bus, is used to measure the temperature of the X6000 DC source system storage pile. The hardware, interface and software are designed and the condition description of the interface routine and realization are given. The system possesses of many advantages, including its novel structure, simple circuit and expedient control.
