便携式分段测速仪的研制

Development of Portable Measuring Set for Position Versus Time

提出了采用红外线脉冲光发射与接收装置检测运动员位置信息,并由无线信号发射、接收与转换电路将此信息传送给单片机,单片机记录下相应的时间信息,进而计算并显示运动员通过各个测量路段速度的方法,设计了软硬件.

Using pulse infrared emission and incept equipment, the paper destects the position information of athlete. This information is transmitted to microcontroller by wireless signal emission and incept equipment, the microcontroller records the time at the moment.The speed of the athlete via every section is measured and displayed by the microcontroller system.The hardware and software of the system are designed.
