Application Name:
Seed drill
 
Application Description:
This application controls all wheels that run over the sowing beds. When a wheel begins to turn slower or stops in relation to the reference wheel, an alarm is activated in the tractor cabin. This allows the speed of all wheels to be monitored. The machine is also capable of self adjustment when one or more of the sowing elements are not running exactly over the sowing bed. The sowing elements will then be moved individually to the correct position. A hectare counter is installed on the sowing drill to allow the operative to monitor how many hectares have been sown. This calculates the distance travelled by the reference wheel. The working width of the machine after one or more sowing elements have been raised is automatically taken into account when calculations are made. The hectare counter equipped with GPS, is still in the testing phase.
 
This application is innovative and has the following unique characteristics:
  • Real-time control of all sixteen seed rollers
  • Automatic shifting of sowing elements
  • Hectare counter
  • Hectare counter using GPS
 
What are the advantages of this application for the end-user?
  • The land is sown uniformly.
  • Sowing bed lines are maintained by shifting the sowing elements.
  • A clear HMI (touchscreen) allowing the operative full control.
 
 
How does this application contribute to environmental sustainability?
  • Improved yield from the land sown, due to the operative being alerted when a roller is jammed. 
  • The seed drill can be operated by one person and all controls are automated. 
 
What does the S7-1200 PLC control?
The PLC monitors seventeen pulse counters, one being fitted to each wheel. The number of pulses per unit of time determines the speed of each wheel individually. When one wheel, percentagewise, begins to turn slower than the reference wheel, the PLC will sound an alarm buzzer while displaying the wheel concerned on the HMI display. The PLC also controls the seven valves responsible for shifting the sowing elements individually.
 
Why is the S7-1200 so suitable for use with this application?
  • Compact with sufficient calculating capacity and a simple code
  • The S7-1200 is extremely good value for money.
  • Easy to expand and combine
  • Profinet
