Abstract

The invention relates to a miss-seeding detection device and method for a corn precision seeder and belongs to the technical field of automatic detection. The method comprises the following steps: determining the corresponding seeding time interval according to the traveling speed and seed metering speed of the corn precision seeder and the required corn plant spacing; determining the miss-seeding alarm time sensitivity and non-uniform seeding alarm time sensitivity according to the seeding time interval, and judging whether the miss-seeding or non-uniform seeding phenomenon occurs in the corn precision seeder. The specific conditions of the corn seeding operation can be fully considered, the detection is accurate, the functions are practical, the performance is stable and reliable, the method has high reliability and real-time property compared with the previous miss-seeding detection, and the requirements matched with the precision seeder are met.

Description

technical field [0001] The invention relates to a missed sowing detection device and method for a corn precision sower, and belongs to the technical field of automatic detection. Background technique [0002] Precision seeding technology has the advantages of saving seeds and high yield. With the development of modern agriculture and the adjustment of agricultural industrial structure, precision seeding machines are more and more popular among farmers. However, most of the corn precision seeding machines currently used in China are mechanical Because the corn precision seeder has the characteristics of a fully closed sowing process during the sowing operation, it is impossible to directly monitor the quality of its operation by human audio-visual, such as the emptying of the seed box and the occurrence of seeding during the sowing operation. Technological failures such as blockage of pipe debris, failure of seed metering device, blockage of opener by soil clods, or failure o...
