Abstract: A multi-nodes monitor system which based on embedded and CAN bus technology was proposed in this paper. Firstly， the basic hardware structure was analyzed， the basic theory and the realize method of the modules are emphasized. The tested signals were illuminated and the ADC method was also discussed in this paper. According to the requirements of communication task， the CAN bus communication method was also discussed， including the software design and the constitutions of the data frames. Finally， experimental results show that this system is stable， lower cost and easy to expand.
