摘要
为了提高精密播种机的工作质量和自动化水平,研制了工况自动监控报警系统及播量数显系统。该系统利用红外光敏对管作为传感器,采用中规模集成电压比较器、555时基电路及40110计数译码驱动电路,实现了对精密播种机工况的自动监控和播量累加数字显示。
In order to improve the drilling quality and the automation of the precision drill, an automatic monitoring alarm and digital seed rate display system was developed. It is composed of medium scale integral voltage comparators, 555 time base circuits, 40110 counting decoding drive circuits and infrared photodiode sensors. It can automatically monitor the working process of the precision drill and display seed rate in digit.
