摘　　要：介绍了一种专门使用数字信号处理器(DSP)和可编程逻辑器件(CPLD)来实现数字强震仪的低功耗设计,给出了系统的结构框图,并且就数字强震仪在硬件设计和软件实现的节能技术进行了描述。该强震仪完全能够满足自由场的强震观测和建筑物的结构观测。In this article, the advanced design technology of Low-powered Digital Strong Motion Accelerograph that is mainly used DSP and CPLD is introduced. The system structure block is presented and low-powered solutions in hardware and software design is described. Finally the article gives the conclusion that the system can satisfy the need of strong motion observation in freevspace field and structure.
