Aiming at the problems of low precision and difficulty in accurate seedling monitoring of small particle size vegetable seeds in current vegetable seeding operation

a single grain precise seeding monitoring system is developed based on fiber-optic sensor and LabVIEW.The fiber-optic sensor and fiber amplifier are used for seed detection.The photoelectric encoders are used to collect the speed of the conveyor belt and the seeding wheel.A hardware system based on data acquisition card is designed

and the software is developed on the LabVIEW platform.A single grain seeding monitoring test is conducted using three types of vegetable seeds of different particle sizes.The test results show that the accuracy rate of single grain seeding monitoring with a particle size of 1 mm or more is more than 97.37 %.The system monitors well and can meet the actual demand for single grain precise seeding monitoring.
