多媒体定时器在EIT数据采集精度评价中的应用
Application of Multimedia Timer in Evaluation of Precision of EIT Data Acquisition
摘要
Abstract
Objective To realize fast data acquisition and storage in the performance evaluation software of high-precision data acquisition system of electrical impedance tomography(ElT). Methods Two kinds of Windows timer were compared and the performance evaluation software of EIT data acquisition system was realized respectively based on Visual C++. Results Both two timers were able to complete the tasks about EIT data, such as acquisition, display, storage and simple processing. However, multimedia timer, whose timing accuracy was higher, was able to complete all the above tasks precisely and effectively. Conclusion Multimedia timer is reliable and can meet the general requirements of high precision timing.关键词
