Abstract: In this research, a mainly purpose of reaching electrocardiogram measurement by integration of designed virtual instrument based on LabVIEW and hardware circuits is described. By acquiring signal from external hardware circuit and transferring it into digital data via A/D transistor then transmitting signal though RS232 to PC, virtual instrument operates those signals and plots them in real-time on the human-mechanic interface, which user can adjust, save, load, even print experiment results. The development of this research includes four phases: (1) designing of human-mechanic interface of virtual instrument. (2) configuring and planing of RS232 serial port. (3) signal processing and transferring. (4) signal operating, finally archives the aim of display, adjusting waveforms, evaluating heart beat per minute(BPM). From theory to construct measurement system in practice, this research not only shows the multiple functions, but also demonstrates the programmable of virtual instrument, and which proceed the measurement test of the designed PC-based virtual electrocardiogram instrument to show the capabilities.
本研究旨在透過心電圖先備知識的了解,藉由LabVIEW圖控軟體所設計之虛擬儀器與硬體電路的整合來達到心電圖量測目的。在這篇研究中,以虛擬儀器實踐心電圖量測技術,由心電圖外部硬體電路所擷取的信號由A/D轉換器轉換成數位資料後,經RS232串列阜輸入至個人電腦,透過虛擬儀器將信號做運算,使得心電圖信號得以即時顯示於虛擬儀器,並可由使用者任意調整、儲存、載入、列印實驗波形。在本研究發展的過程中,包括(1)虛擬心電圖儀器之人機介面設計(2)串列阜設定與規劃(3)信號處理與轉換(4)信號運算等四階段,最後達成心電圖輸出顯示、調整、計算每分鐘心跳數等研究目的。在整體技術發展中,從理論到實際系統建構過程中上,顯現虛擬儀器可程式設計之開放、功能多元與可任意更改其人機介面之特性,其量測技術最後以實際功能測試來驗證所設計的虛擬心電圖量測儀器之可行性。
