摘　　要：介绍了一种新型多路故障录波装置的原理和软硬件实现方法。该装置采用接受GPS触发方式,可实现 24路信号的同步采样,采样频率为单通道250kHz,采样精度为16位,它通过基于FPGA的硬件在系统可编程技 术,根据不同的录波对象方便地管理采样通道,PCI总线接口保证了其实时性和通用性。This paper presents the principle and the realization method of a new multiplex channel fault wave-recording device. The device is triggered by GPS and can achieve synchro-sampling of 24 digital input. The rate of sampling can reach 250 KSPS per channel, and the precision of sampling is 16 bit Moreover, this device can easily manage the working method of sampling channels in accordance with the different wave-recording objects by the hardware ISP (In System Programming) technology of FPGA. The PCI bus ensures its real-time and universal characteristic.
