摘　　要：针对油耗仪输出TTL信号或输出正交信号的不同情况,提出一种基于dsPIC30F6010A正交编码器接口的通用型油耗仪输出信号接口模块设计方案,给出了其具体的软硬件实现。实践结果证明,该模块可以方便、准确地采集两类油耗仪输出信号。In this paper,a new program of universal interface module for fuel consumption meter output signal was designed based on dsPIC30F6010A.The module hardware structure and software design method were also introduced in detail.The experiment results showed that the fuel consumption meter output signal,including TTL signal and quadrature signal,could be acquired easily and accurately.
