Abstract
An Intelligent Answering and Voter-timing Machine Based on AT89C51 MCU is designed. Priority encoder circuit, the latch and the decoding circuit are designed, respectively, and in the same the input signal of participating team is separately diplayed on the monitor. The alarm circuit is started by the control circuit and the host switch, timing circuit and decoding circuit can generate second-pulse output signal to achieve timing function. After the experiment analog and simulation, the results shows that the answering has characteristics with quick, multi-functional and strong practical features.
