本文主要得目的在改善心跳信號中的R波取出,並以5.5KHz無綫電波傳送。因為是5.5KHz無編碼電波傳送,發射機在每次心跳均發送一次電磁幅射脈衝,而接收機亦只是接收此幅射脈衝並予整型成方波送給計算平台做心跳值之計算,因此系統的穩定必須多方面整體考量。經實驗證明,布質胸帶的貼身性使得取出信號更穩定也更適合長時間配帶。在接收機電感並聯諧振設計及系統各分件完整考量能使接收機降低雜訊干擾提高信號判別能力。接收機下方墊海綿有阻尼機械振動效果,有效防止振動造成接收天綫產生錯誤信號。
經上述改善使得5.5KHz在電動跑步機市場仍是俱成本競爭力的無綫心跳信號傳輸適當選擇。
The main subject of this paper is to detect the ECG R wave by using only two uniploar leads and the wireless transmit the heart beat pulse by 5.5KHz frequency.
Due to the non-coded transmittion each heart beat will occur a 5.5KHz radio frequency radiation to the receiver side, the receiver receives the radiation pulse then form as a square wave for console calculation to count the heart rate value.
By the experiments found that the textile chest belt design could have more stable heart signal pick-up, more comfortable for long-time wearing so that more suit for the using of sporting purpose.
The detail analysis and considerations for each section of the system such as the pair resonation of conductance and capacitance design and the sponge added under the receiver module PCB board as a damping effect which can reduce mechanical vibration which makes the system more reliable.
The results of the study founds as an application for treadmill wireless transmittion purpose , 5.5KHz radio frequency still is the competitively chose .
