摘　　要：分析了分时采样技术在刚性罐道弯曲检测方面的缺点,结合同步采样的相关技术,介绍一种基于AD7874芯片的同步采集系统,并应用于刚性罐道弯曲检测的实践当中,取代了以往的分时采样技术,克服了同时采集多个信号的困难,并使硬件电路较为简单。The disadvantage of time - sharing sampling technology in the rigid cage - way bend testing system is analyzed. Associated with the synchronous sampling techniques, the synchronous acquisition system based on AD7874 chip is introduced, and applied to rigid cage - way bend testing system. It can replace the previous time- sharing sampling technology and gets more signals at the same time , Also, it makes more simple hardware circuit.
