【摘要】 基于自主研发的便携式电子实验系统,开发了可同时实现单车测距和测速的综合性实验项目。通过传感器把车轮转动信号转换成脉冲电信号,由FPGA实现测量和显示控制,测量结果由液晶显示器显示。误差≤5%,响应时间≤5 S。该项目可用于电子技术课程设计,为后继科技创新活动提供思路。更多还原

【Abstract】 Based on self-developed portable electronic experiment syntem, a complehensive experiment project for bycicle range and velocity mesurement has been developed. Sensor circuit converts the wheel rotation signals to eclectronic pulses. The FPGA contributes to the counting and display control. LCD displays the measurement results. The error is less than 5%, and the response time is less than 5 S. This project is mainly applied to electronic technology curriculum design. It also provides ideas for scientific and technological innovation activities.更多还原
