本研究针对无线感测模组及个人数位助理（PDA）的耗电问题，开发心电遥测装置。此外，还对Zigbee心电传感器模块与PDA之间的数据传输速率进行了分析。使用两个AAA电池串联，传感器模块的工作时间平均超过28小时。PDA的功耗取决于屏幕开/关条件和串行端口使用情况。在该应用中，PDA的操作时间平均为4 ~ 5小时。PDA采用非阻塞方式对串口传输的数据进行处理。传输速率取决于数据包结构。当每个数据包由5个ECG数据和3个加速度数据组成时，其为300个ECG样本/秒。总之，传感器模块的功耗和移动的医疗设备的传输速率没有问题。但是，PDA存在功耗问题，这是一个亟待解决的问题。
In this study, power consumption issues of wireless sensor module and personal digital assistant(PDA) were addressed to develop ECG telemetry device. In addition, data transmission rate between Zigbee-based ECG sensor module and PDA was analyzed. Using two AAA batteries in series, operating time of the sensor module was above 28 hours in average. Power consumption of PDA was dependent on screen ON/OFF condition and serial port usage. In this application, operating time of PDA was 4∼5 hours in average. PDA processes the transmitted data through serial port using nonblocking method. The transmission rate was dependent on the packet structure. It was 300 ECG samples/sec, when each packet was composed of 5 ECG data and 3 acceleration data. In conclusion, there was no problem in the power consumption of sensor module and transmission rate for mobile healthcare devices. But, PDA has the problem of power consumption, which should be solved.
