Monitoring system and method for seed discharge flow of seeder

Abstract

The invention provides a monitoring system and method for seed discharge flow of a seeder. The system comprises a falling seed dispersing device, an optical fiber monitoring module and an industrial personal computer; the falling seed dispersing device is arranged at the seed discharging opening of the seeder; a feed inlet and a shunting groove are arranged in the falling seed dispersing device; the minimum end of the feed inlet is connected with the shunting groove; the optical fiber monitoring module comprises an optical fiber emitter and an optical fiber receiver; the optical fiber emitterand the optical fiber receiver are respectively arranged at two sides of the normal direction of the shunting groove; the output of the optical fiber monitoring module is transmitted to the industrialpersonal computer; the industrial personal computer is arranged in a cab of the seeder; the back surface of the industrial personal computer is provided with a coordinator for receiving the data output by the optical fiber monitoring module; and the industrial personal computer comprises a light quantity change value calculation module, a light quantity change value accumulation module, a shielding number counting module and a seed discharge flow forecasting module. The monitoring system and method provided by the invention can solve the problem of accurate monitoring of discharge flow.

Description

technical field [0001] The invention relates to the technical field of agricultural electrification and informatization, in particular to a system and method for monitoring seed flow rate of a planter. Background technique [0002] Sowing quality is one of the important factors affecting crop yield. Therefore, the monitoring of sowing quality is a hot research direction of intelligent sowing system. Traditional planters rely on the operator standing at the rear of the machine to identify re-seeding and missed sowing. This method is labor-intensive and has low monitoring accuracy, which is not suitable for large-scale sowing operations. [0003] In recent years, researchers in the field of agricultural engineering have actively explored more accurate and intelligent monitoring methods, and the hardware devices and monitoring methods used to monitor the flow of seeds have been continuously introduced. Patent No. CN201210144176.5 provides a missed seeding monitoring method, wh...
