基于AVR的嵌入式在线监测系统的设计

his paper introduces one embedded system used for the online monitoring of middle and small scale key machinery. The system applies AVR single-chip, it could acquire 32 channels of analog signals coming from onsite sensors within the same time, after processed in the acquiring card, these signals will be transferred into the senior computer in order to actualize the real-time online monitoring for the machinery equipments. This system applies battery as the power supply, and turns into power-saving module when free, therefore the power consumption is very slow.
