摘要
介绍了一种以89C51单片机为核心器件的抽油机示功仪的组成及其工作原理。该示功仪通过检测光杆位移等间隔采样光杆载荷，得到一组光杆载荷数据，并对数据进行3△滤波，通过微型打印机打印示功图。
Firstly, the structure and the working principle of a new pump well indicator based on the microchip 89C51 are introduced in this paper. Then, a set of loading data is obtained by detecting the shift and sampling the rod, and processed by 3△ filtering, the indicator map is printed by a micro-printer.
