Abstract
A device for monitoring seeding and a method thereof, including a monitoring sensor and an algorithm control module, wherein the monitoring sensor includes a first sensor-channel emitting end, a first sensor-channel receiving end, a second sensor-channel emitting end and a second sensor-channel receiving end, and are arranged, in a two-channel opposite-emission photoelectric induction mode, on two sides of a seed belt, respectively; and the algorithm control module is configured to perform counting of seeding, reseeding and missed seeding, monitoring of seed deficiency and seed blockage according to a duration time of a first low level and an interval time of two adjacent falling edges of signals of the two sensor-channels; further, to perform monitoring of a rotating speed of a motor according to an interval time of two adjacent falling edges of signals of the second sensor-channel.
