摘　　要：介绍了以一款浮点数DSP芯片TMS320VC33为控制核心的16通道高速同步数据采集系统的硬件设计。采用了锁相环电路对周期信号进行同步跟踪和控制采样,通过4片4通道高速模/数转换器AD7865与TMS320VC33接口来实现数据采集,并使用复杂可编程逻辑器件(CPLD)来实现采集系统硬件模块的地址分配。该数据采集系统已应用在无功发生器STATCOM的研制中,为STATCOM的设计提供了完善的前端处理电路。Introduction was made to the hardware design of sixteen-channel high-speed synchronous data acquisition system with float point digital single processor chip TMS320VC33 as control core, adopting phase-locked loop （PLL） circuit to have cyclic signal tracked and sampled simultaneously. Date acquisition was achieved via 4 pieces of four-channel high-speed A/D converter AD7865 with TMS320VC33 interface, and complex programmable logic device （CPLD） was used to realize acquisition system hardware module adress distribution. The data acquisition system has already been applied in the manufacture of reactive generator STATCOM, providing it with complete front end processing circuit.
