摘　　要：为实现同步采集道路载荷谱数据并保存,设计开发了一套车轮力传感器(wheel force transducer,WFT)数据采集系统.文中详细介绍了该系统的软硬件构成,硬件采用PC104主板,软件采用了Linux下的多线程技术,实现了既可以通过自身按键进行控制也可以通过以太网远程控制的WFT采集多串口数据转以太网服务器的设计.测试与试验表明:系统可以稳定可靠地采集各通道传感器数据,能够满足道路载荷谱数据采集的性能要求,作为自主研制的车路测试仪器具有重要的应用价值.In order to synchronously acquire and save road load spectrum data, a set of wheel force transducer （WFT） data acquisition instrument is designed based on Linux system. The instrument design of software and hardware is described in detail, of which the hardware adopts PC104 motherboard and the software adopts multi- thread technology under Linux development environment. As a transmission server from multi-serial ports of WFT data acquisition to Ethernet, the data acquisition process can be controlled by command buttons or Ethernet. Ex- periment results show that the instrument works steadily and reliably. It meets the road load spectrum data acqui- sition performance requirements, which has an important application value as independently developed car-road test equipment.
