基于单片机的智能型无刻度电子卷尺设计

Design of intelligent electronic tapeline without scale based on MCU

提出并设计了微电脑智能型电子卷尺。该设备由机械装置、电路和软件3大部分组成,并利用单片机计算、显示、存储以及传输测量的数据。该设备操作简单、测量精确、数据存储量大,并且具备与计算机通讯的功能。其工作状态完全不受恶劣的工作环境影响,可取代目前国内油田现场中对油井管杆人工测量的方式。

The intelligent electric tapeline was presented and designed. The equipment was consisted of mechanical unit, circuit and software. The measured datum was calculated, shown, stored, transported by micro control unit （ MCU）. The equipment is easy to manipulate, measures accurately and has large space to store datum and the function of communicating with computers. The working status of the equipment would not be influenced by bad working environments at all, it can replace the present manual measuring ways for oil well pipes on oil fields in china.
