| Abstract: |
| The annunciator system for no-tillage drills,
comprising complete digital circuits and photoelectric sensors, is developed. It is
scalable, expandable, accurate and applicable. By adjusting the resistance-capacitance
properties, the system can monit the seeding of different plants. The PC-based automate
test system is also researched to provide the detecting data of the system. |
