摘　　要：管线投入运行后,在服役期间均需要进行检测。本文对FPGA及其相关的开发软件进行了简要的介绍,并提出了一种利用FPGA(现场可编程门阵列)对检测时的多路信号进行采集与存储的方法,对FPGA在其中完成的功能以及它的内部资源划分进行了描述。本方案可简化检测装置的外部电路设计。同时,把FPGA与MCU结合起来,使FPGA可以应用于其它嵌入式应用系统,增加了检测装置的通用性。Any pipelines which are used need steady-period inspection. This article briefly introduces the FPGA （Field Programmable Gate Array） and its relative development software, and brings forward a method which takes advantage of FPGA to collect and save multiplesignals during the inspection. And meanwhile, we make a description about FPGA＇s function and discuss how the resources inside are divided. We think that circuit design of the inspected setting will be predigested in our project. At the same time. the combination of FPGA and MCU will spread its application to other embedded system, which makes the setting used more generally,
