本文介绍了一种用超声进行调制的水下心率遥测系统,可获得80m深度水下作业潜水员的心率。超声调制频率为41.7KHz。现场使用表明,该系统能在湿式和干式两种状态下,实时监测潜水员潜水时的心率变化。
This article presents an underwater heart rate telemetry system that is modulated with ultrasound to obtain a heart rate for a submerged diver at a depth of 80 meters. The ultrasonic modulation frequency is 41.7KHz. Field use shows that the system can monitor the diver’s heart rate changes in real time under both wet and dry conditions.
