摘要
介绍了一种基于AN2131QC芯片的USB接口高速数据采集系统的设计和实现方法,并采用该系统进行了车辆操纵稳定性和车辆车身振动加速度测试试验。采集的试验数据经三次样条法处理,基本符合预期的结果。该数据采集系统符合USB2.0协议,是一种新型的数据采集系统,实现了USB设备的即插即用功能。
The paper discusses the realization of data collective system based on USB controller-AN2131QC chip. The system is used in the testing on vehicle＇s capability. The test is also made for the car＇s body vibration acceleration, seat chair＇ acceleration of car and the force of steering wheel when the car is droved like snake. The data collected basically matches the anticipative result. The system is in accordance with USB2.0 protocol, and realizes the function of plug-and-pull for USB device.
