Analysis on Uniformity of Seeding Based on Photoelectronic Detection Principle
For problems existing in seed-metering device uniformity testing, use photoelectric detection technology on seeding uniformity testing. Its working principle is to use optical sensors to monitor the situation that seeds passing through the seed channel, records the cumulative number of seeds of each channel by counting chips and MCU and periodically send to the PC, obtaining relevant data such as seeding uniformity of seed-metering device through further data analysis. Tests showed that under the same conditions, relative error between test data of the system and manual measured data is less than 5％, meet the actual needs. At the same time, compared to manual measurement, the system also has advantages of low cost, easy operation, without calculation and continuous online work available.
