GAGE82G采集卡在激光测距机中的应用

Application of GAGE 82G Acquisition Card in Laser Rangefinder

将高速采集卡GAGE82G应用于激光测距机,其硬件设置含采样速率、采样模式、触发源、触发深度、输入电阻、触发沿等参数。采集卡程序设计包括:初始化驱动程序和硬件、准备采集卡的数据获取、获取数据、判断采集完成情况、传输数据、计算距离等。该应用以VC++.net作为开发平台,1秒内可得到所测的距离信息。

The Gage 82G high-speed data acquisition card was applied in laser rangefinder, its hardware setting parameter includes sample rates, sample mode, trigger source, trigger depth, input impedance and trigger slope. Sample programs consists of initializing the Gage 82G driver and hardware, preparing the card to capture data, starting an Acquisition data, analyzing instance of completing an acquisition, transferring the Data, calculating distance and so on. For the application, the data of measured distance was received within 1 second, under VC＋＋.net development environment.
