Problems solved by technology

However, once the wheels of the driving mechanism slip in this method, there will be a large error in the calculation of the walking distance, which will directly affect the accuracy of the leakage monitoring
This method also cannot record missed broadcast information
However, it has not been found that the use of GPS technology in the seeder leakage detection system has not yet been found.

Embodiment Construction

[0027] In the present embodiment, a kind of GPS-based seeder miss-seeding judging device, the seeder utilizes the seeder to sow, and the seeder is provided with wheel speed sensor and miss-seeding detector; The composition of the seeder miss-seeding judging device comprises: GPS mobile station, GPS reference station, GPS signal receiving and processing unit and alarm unit installed on the seeder; such as figure 1 As shown, the sensor unit is composed of GPS mobile station, GPS reference station, wheel speed sensor, missed broadcast detector and other sensors; differential information transmission can be completed between GPS mobile station and GPS reference station through digital radio station, GPRS or 3G module . The invention adopts 3G network for real-time transmission; adopting the 3G transmission mode has the advantages of long transmission distance and strong anti-interference ability.

[0028] The GPS reference station is arranged near the actual working place to gene...

Abstract

The invention discloses a device and a method for judging miss-seeding of a seeding machine based on a GPS (Global Positioning System). The device is characterized in that a wheel speed sensor and a miss-seeding detector are arranged on the seeding machine; the judgment device comprises a GPS mobile station, a GPS datum station, a GPS signal receiving and processing unit and a warning unit. The device and the method can accurately judge the miss-seeding situation and record the miss-seeding position, and is high in accuracy and strong in operability.

Description

technical field [0001] The invention belongs to the application field of modern high technology in agriculture, and more specifically relates to a GPS-based device for judging missed sowing of precision seeders and a judging method thereof. Background technique [0002] In recent years, with the development of precision seeding technology, precision seeder has become the main feature of modern seeding technology and the main development direction of seeding. However, in the seeding operation, the process of seed flow is uncertain, and the quality of the operation cannot be directly judged only by human vision and hearing. When the seeder is working, technological failures such as the emptying of the seed box, the blockage of the seed delivery pipe, the failure of the seed metering device, and the failure of the seeding transmission will cause one or several rows of seed pipes to fail to sow normally, resulting in "broken" "Strip" missed seeding phenomenon, especially large-...
