摘要
试验机系统需要使用多路不同类型的传感器,而多路传感器模拟信号的同步采集对于后期的数据处理和分析至关重要。因此,设计了一款AD采集卡,该板卡可以同步采集16路模拟信号。本文对该板卡软硬件设计进行了介绍,在Quartus Ⅱ软件下对FPGA内部逻辑电路进行仿真,验证了其逻辑功能的正确性。
Many different types of sensors are needed in the systems of testing machine. Synchro- nous acquisition of multi-channel sensors analog signal is essential for post-processing and analy- sis. Therefore, a board that can synchronously collect 16 analog signals is designed. In this pa- per, the design of the software and the hardware are introduced. The Quartus II software is used to simulate the internal logic circuit of FPGA, which verifies the correctness of the logic functions.
