Multi-row infrared seed falling detection system suitable for no-tillage planter

The invention belongs to the technical field of crop seeding, and particularly relates to a multi-row infrared seed falling detection system suitable for a no-tillage planter, which comprises an infrared seed falling detection sensor module, a miss-seeding judgment module, a seed falling detection controller and an abnormal alarm module, an infrared seed falling detection sensor in the infrared seed falling detection sensor module is arranged at the bottom of each row of seed guide pipes. The invention is based on the principle that the seed falling interval time is short, the speed change of the seeder in the seed falling interval time is limited, and the seed falling interval time change is limited. According to the system, by recording the seed falling interval time and integrating the multi-row seed falling interval time, the problems that the seed falling time interval calculated through the standard vehicle speed in miss-seeding detection of infrared seed falling detection cannot adapt to the actual veh
