Mutual information between personal computer and the scene signal transferred through the multi-function data collecting car . Then the calibration system implemented the data acquisition display and storage as well as controlled the executive machine .

PC机和现场信号通过多功能数据采集卡交互信息，实现了标定系统的数据 采集、显示和存储以及对执行机构的控制。

The digital signals are transferred by the digital acquisition system and PCI bus in the receiver which can implement high-speed data channel in current computer using DMA mode and double side address map .

接收机中数据 采集 卡使用模数转换器件和PCI总线来 传输高速数字信号，该系统工作在通用计算机上，采用DMA方式和双端地址映射方法实现高速数据传输。

The pull force and stretch length signals are transferred from the pull sensor and displacement sensor during the process of stretching . After the signal is pretreated it is communicated to the data acquisition card .

采用拉力传感器、位移传感器来测量拉伸过程中吊装 带所 承受的拉力和延伸长度，经信号调理后，送入数据 采集卡。

The sampled data was transferred from the data acquisition box to the computer through the enhanced parallel port ( EPP ) .
