【摘要】 本系统采用MCS-51单片机实现了精密播种机排种性能监测。对重播、漏播分别进行不同方式的声光报警，可定量计算重播率、漏播率及合格率，并送显示器显示。也可根据需要将这些参数打印下来，确保精密播种的质量。更多还原

【Abstract】 MCS - 51 single chip microprocessor was adapted in this system to detect the preciseseeder’s seeding and to sound the alarm in different sonic and light ways for re - seeding or lap-sus seeding. The re - seeding rate, lapsus seeding rate and qualified seeding rate can be comput-ed and displayed by fixed quantity. If it is necessary, all the data will be printed so that theSeeding qualification of precise seeder can be ensured.更多还原
