【Abstract】 An infrared testing system which can control the transfusion accuracy is designed. Two photoelectric sensors are used in this system to insure the accuracy. 5 V DC power is supplied through the USB interface. The signal conditioning circuit is used to process the signal obtained from these photoelectric sensors. Using the USB technology to implement the communication between host and the data acquisition card. This software compiled by VC includes mainly: data display, graph show, data processing and storage. The experimental results show that this system has excellent performance, convenient operation and meet the requirements of precision.更多还原
