摘　　要：为了实现对58路模拟信号进行不同频率的采集,设计了一种以现场可编程门阵列(FPGA)为核心的多路模拟信号采集模块。该模块采用FPGA芯片XC2S30作为系统的核心控制器件来实现对A/D转换器的控制、多路模拟开关的选通控制以及数据的编帧和并串转换等功能。该设计方案结构灵活、控制简单、可靠性高,并且通过试验已验证了其功能的正确性。A multi-channel analog signal acquisition module which took the field programmable gate array （FPGA） as the core was designed to implement the data acquisition of different frequency to the 58-channel analog signals. The FPGA chip XC2S30 of XILINX Corporation was used as the control device to achieve the following functions, the A/D converter control, analog multiplexers control, data coding, the conversion of the parallel data to serial data and so on. The program structure of the design is flexible, easy to control, very reliable, and its function has been validated through test.
