摘　　要：针对目前末敏探测试验中多通道红外信号采集以及远距离传输的需求,该文设计了一种基于FPGA的多通道红外信号采集系统。该系统以FPGA作为主控制器,使用3片AD7606模数转换器进行信号采集,并外接DDR3 SDRAM作为数据缓存,最后使用以太网UDP协议将数据传输至上位机。测试结果表明,该系统能够对24通道红外信号进行采集、传输以及数据保存,采样率可达200 kHz,性能稳定,具有较高的应用价值。Aiming at the requirements of multi-channel infrared signal acquisition and long-distance transmission in terminal sensitivity detection test,a multi-channel infrared signal acquisition system based on FPGA is designed.The system takes FPGA as the main controller,uses three AD7606 analog-to-digital converters for signal acquisition,and external DDR3 SDRAM as data buffer.Finally,the data is transmitted to the upper computer using Ethernet UDP protocol.The test results show that the system can collect,transmit and save the 24 channels infrared signal,and the sampling rate is up to 200 kHz,with stable performance and high application value.
