播种机多项性能检测及图形打印装置

A Monolithic Micro-computer System for Planter Performance Measurement and Graphic Printing Output

开发了一种基于 80 31单片机的播种机多项性能检测装置。该装置具有脉冲计数、统计计算、显示打印等功能。结合不同的传感器 ,可以完成播种机排种均匀度和排种数、排种器轴的转速、拖拉机前进速度、播种机地轮滑移以及拖拉机驱动轮滑转等多项检测。速度检测能够打印曲线 ,排种检测除能打印统计数据外 ,还能够以点阵图形打印出种子在种沟分布的田间效果模拟图。

To meet the needs of the planter study and appraising, a measuring system of planter seeding performances based on 8031 monolithic micro computer was developed. Combine with different sensors, the detecting functions of this system include the seed space uniformity of metering device, the rotate speed of the axis of metering device, the velocity of tractor, the slippage of planter wheel and the width of the signal pulse. The processes to the test data are statistic, calculation, display and printing. The special printings are speed curve, data distributing and especially the simulating graph of seeds distribution on the field.
