Brief Description of the Drawings

The proposed system for monitoring the operation of a grain seeder during sowing is illustrated by a block diagram illustrating an example implementation of a utility model.

Utility Model Example

The proposed system for monitoring the operation of a grain seeder during sowing is intended primarily for wide-seeder grain seeders with a working range of up to 18 m. Usually, the seeder is equipped with hoppers for seeds and fertilizers, sowing devices and a pneumatic system serving the sowing devices and other units of the seeder. A wide-seeder can have more than 100 sowing machines. To achieve uniform intervals between the seeds in the soil, to control the fertilizer application rate and to control the rolling mode after sowing, it is necessary to monitor the change in the main controlled parameters of the seeder and, first of all, it is necessary to measure the seed flow rate with each sowing device. In addition, you need to know the speed of the drill in order to determine the sowing area and monitor compliance with the seeding rate. Thus, it is necessary to constantly monitor the operation of sowing devices and auxiliary devices.

To monitor the sowing process, we propose a system for monitoring the operation of a grain seeder during sowing, which contains a multichannel system for measuring the controlled parameters of the seeder located on the seeder, which includes sensors for measuring the controlled parameters, including sensors 1 for the flow of grain on each single-grain sowing device, level 2 sensors grain in the hopper, air pressure sensor 3 in the pneumatic system of the seeder, and sensor 4 of the speed of the seeder. In addition to these sensors, the seeder can contain sensors for monitoring the operation of any seeder units, for example, sensors 5 for monitoring the status of sowing devices. The system also contains an on-board information computer system, including a computer 6 for servicing the seeder and other units of the sowing complex, including for processing measurement data and a display 7 connected to it to display the characteristics of the sowing complex, including for displaying the measurement results of controlled parameters . Computer 6 and display 7 are located at the workplace of the drill operator. At the workplace is also placed remote control 8 connected to the computer 6.

The system for monitoring the operation of a grain seeder during sowing also contains a system for transmitting data from sensors 3-5 measuring controlled parameters to a computer 6. The basis of the data transfer system is an interface bus 9 installed on the seeder with a controller 10. Controller 10 is capable of multiplexing data from sensors 3 -5 measurements of monitored parameters in a single data packet, which includes measurement data of all sensors 3-5 measurements of controlled parameters and the transmission of this single data packet by Yeh-lii multiplex communication line that connects the output controller 10 to the computer 6. The controller 10 may also perform a multiplexing of all other data transmitted from the computer planter or seeder 6. workstation operator can be equipped with positioning system 11, e.g., using GPS.

Computer 6 performs the reverse operation of demultiplexing the received data packet and extracts measurement data of the monitored parameters from the sensors 3-5 from this received data packet. Next, the computer 6 performs the processing of this data and presents the results of the data processing on the display 7.

In the proposed system for monitoring the operation of a grain seeder, any multiplexing scheme can be used, including a single data packet can be generated using frequency multiplexing or time multiplexing.

It is preferable to use a serial asynchronous bus, for example, a CAN bus, for processing and data transmission.

The description of the present utility model is illustrative and does not limit the scope of the utility model formula.
