Problems solved by technology

Due to the airtightness of the seeding system of the precision seeder, it is difficult to judge the seeding situation only by the operator's audio-visual feeling. For example, the emptying of the seed box, the blockage of the seeding pipe, and the technological failure of the seeding device can all lead to the phenomenon of missing seeding. Once it occurs The above-mentioned large-area missed seeding phenomenon will inevitably cause serious losses in agricultural production.
[0003] At the same time, due to the particularity of the seeder operation site environment and the severity of dust interference, the existing seeding monitoring system is difficult to work normally
In addition, most of the statistics of the sown area currently use the meter ruler measurement method, which is not only troublesome, but also the measurement accuracy is not accurate enough

Embodiment Construction

[0019] The corn precision seeder seeding monitoring system is characterized in that the required equipment and implementation steps of the system are as follows:

[0020] Required equipment: The required equipment of the present invention is mainly composed of 4 parts: a sensor detection part 1, a single-chip measurement and control part 2, an acousto-optic alarm part 3 and an indicator box unit 4. The sensor detection part 1 is composed of a laser emitting diode 5, a convex lens 7 and a laser receiving part 11. The laser receiving part 11 is formed by serially connecting four laser receiving diodes, and the distance between each two laser diodes is 3mm. The laser emitting diode 5 emits a scattered micro-power laser signal 6 with an angle of 60 degrees, which becomes a parallel beam 8 after passing through the convex lens 7 and is received by the laser receiving part 11 . The single-chip measurement and control part 2 is composed of LM358 amplifier 13, LM393 comparator 14, key...

Abstract

The invention relates to a seeding monitoring system of a corn precision seeder and belongs to the technical field of agricultural machinery control. By means of the singlechip intelligent control and photoelectricity detection technology, the seeding monitoring system has the functions of counting seeding grains, automatically calculating seeding areas, alarming leaked seeding and the like. The seeding monitoring system aims at severe environments of agricultural machinery working sites, solves the problems of inaccurate counting, large errors, poor antijamming capability and the like and comprehensively improves quality of seeding operations.

Description

technical field [0001] The invention relates to a monitoring system for seeding of a corn precision seeder, and belongs to the technical field of agricultural machinery control. Background technique [0002] Precision seeding technology has the advantages of high efficiency, fast operation speed and convenient operation. It is widely used in agricultural production and is an inevitable trend of agricultural modernization and mechanization development. Due to the airtightness of the seed metering system of the precision seeder, it is difficult to judge the seeding situation only by the operator's audio-visual feeling. For example, the seed box is empty, the seed metering pipe is blocked, and the technical failure of the seed metering device can lead to missed seeding. The above-mentioned large-scale missed sowing phenomenon will inevitably cause serious losses in agricultural production. [0003] At the same time, due to the particularity of the working site environment of t...
