摘要
介绍了一种用在跑步机上测定运动员心率的仪器装置——数字式脉搏测试仪。运用了晶体三极管的开关特性和无线收发技术,实现了低功耗和便携的要求,同时运用软件方法实现了信号的快速提取。
A kind of instrument-digital pulse tester is introduced, which is used in the machine for running to test athlete＇ s pulse. The characteristic of power switch of bipolar junction transistor（BJT） and the wireless receiving and sending technique are used to carry out the property of low cost and convenient to carry. At the same time, the method of software is used to realize the fast acquisition about signal.
