Abstract

The invention relates to a seeding monitoring method based on a wheat seeder. The method includes the following detailed steps that (1), an analog voltage signal and land wheel speed data are collected; (2) the analog voltage signal is analyzed according to feature information of the analog voltage signal; (3) the seeding state is determined according to the analyzed feature information of the analog voltage signal and the land wheel speed data. According to the method, a high-power infrared photoelectric seeding sensor is used, the seeding sensor directly outputs the analog voltage signal, a single chip microcomputer is used for collecting the voltage signal, a state judgment algorithm is designed according to features of voltage, voltage change, and continuity and discontinuity of wheat sowing in line, the defect of poor anti-dusting performance of a photoelectric monitoring device is overcome, three seeding states such as normal state, blocking state and blank pipe state can be well monitored, real-time performance and accuracy can be considered simultaneously, and miss-seeding can be timely and accurately discovered. The invention further discloses a seeding monitoring device and system based on the wheat seeder.

Description

technical field [0001] The invention relates to the technical field of computer agriculture, in particular to a sowing monitoring method, device and system based on a wheat planter. Background technique [0002] When the wheat seeder is performing seeding operations, there are often failures such as lack of seeds in the seed box, faults in the transmission of the seeding chain, blockage of the opener, and blockage of the seeding pipe, resulting in missed seeding and reduced crop production. In order to find the phenomenon of missing broadcast in time, the commonly used monitoring methods include manual monitoring method and photoelectric sensor monitoring method. The manual monitoring method requires two people to stand on the seeder to observe the seeding conditions of each row of tubes. However, since the flow of seeds is completely closed during sowing, it is impossible to accurately detect missed sowing in time only by human vision and hearing. Simultaneously, the labor...
