摘　　要：介绍了低速增量式光电编码器接口的鉴向计数原理,以及实践过程中所要注意的问题,并通过实验验证了接口的可行性与适用范围。A method of designing a simple and lowcost interface of the incremental photoelectrical encoder which is used in low velocity system is provided in this paper. The principle of detecting direction and countering is presented in detail and some questions that must be paid attention to in practice are also listed. Further more,the feasibility and the application range of this interface are proved by experiments.
