摘要
失重和超重是力学中两种抽象的物理现象。利用微处理器作为控制单元设计的超重、失重演示仪,精确而且直观地演示出超重和失重的物理现象。整个演示仪以AT89C52单片机为核心,由光电门检测电路、数码管显示电路、按键等电路组成,电路结构简单、性能稳定、易于操作、成本低廉,在实际应用中取得了良好的教学效果。
Overweight and weightlessness are two kinds of abstracted physical phenomena. A new style overweight and weightlessness instrument is designed with microprocessor as control unit, which can accurately and visually demonstrate of overweight and weightlessness physical phenomena. The demonstration instrument with the core of AT89C52, compose of photo-electric gate detection, digital display and switch circuit, whose structure is simple, stable property, ease to operate and low-cost, obtains a good teaching result impractical applications.
