摘　　要：舵机测试过程中,需要采集舵机实际舵偏角用于产品标定和性能评估,传统的舵偏角采集系统是通过基于PCI接口的专用工控机和采集卡来实现的,成本高且对计算机有特殊要求。针对舵机测试中对低成本、通用化舵偏角采集系统的需要,开发基于STM32F103的下位机代替传统的PCI板卡实现数据采集,并通过USB总线与上位机进行通信。基于LabWindows/CVI的上位机软件用于数据通信和界面交互。该采集系统具有成本低、可靠性高、使用方便等优点,已成功用于舵机测试中,并达到了良好的效果。In the progress of servo testing, the actual servo-angle signal is needed to be acquired for the calibration and performance evaluation of the servo system. The traditional servo-angle acquisition system is composed of PCI-based acquisition board and IPC, which has high-cost and needs special computer. For the requirement of a low-cost and universal servo-angle acquisition system in servo testing, a lower computer based on STM32 F103 is designed to instead of traditional PCI-based acquisition board. The lower computer communicates with PC via USB interface. The PC software based on LabWindows/CVI is designed for communication and human-computer interaction. This system features low-cost, high reliability, high flexibility, and it has been successfully applied in servo testing. The experiment results demonstrate the outstanding achievement of the system.
