摘　　要：介绍一种基于STC单片机的计时器设计方法。该系统以STC15F408AD单片机为主控器件,以AT24C64为存储器件,实现对要求严格限时的会议、答辩等场合的时间控制。该设计具有便携、成本低、数据记录存储可查询等特点,可以广泛应用于会议、辩论赛、学术报告或者考试、实验计时等场合。This paper introduces a design method of timer based on STC MCU（Micro Control Unit）. The system uses STC15F408AD MCU as the control device, AT24C64 as the storage device, to complete the control of time for the conferences having a strict limit on time and the defense. The design has the advantages of portability, low cost, records can be queried etc, which can be widely used in occasions such as examination, debate, academic report, the experimental timing and so on.
