BRIEF DESCRIPTION OF THE FIGURES
Figure 1 is a representative schematic view of the subject matter control system.
DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the subject matter control system (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.
In Figure 1 , the schematic view of the subject matter control system (10) is given. Accordingly, there is at least one control unit (30) connected to at least one three-point linkage (40). By means of the commands given through at least one internal control interface (31) associated with the control unit (30), at least one control valve (41) is controlled and a hydraulic unit (42) is operated. Depending on this, the upward-downward movement of the three-point linkage (40) can be controlled.
There is at least one communication unit (50) connected to the control unit (30). There is at least one wireless control device (20) connected to said communication unit (50). The commands entered through a control interface (21) provided on the wireless control device (20) are transferred to a receiver (51), provided at the communication unit (50), by means of a transmitter (22) and from there, said commands are transferred to the control valve (41), provided at the three-point linkage (40), by means of the control unit (30). Thus, by means of the commands given from the wireless control device (20), the upward-downward movement of the three-point linkage (40) is controlled.
In more details, when the operator desires to assemble equipment to his tractor, he uses the three-point linkage (40). After the tractor is brought near the equipment, the operator needs the sensitive movements of the three-point linkage (40) for realizing connection. In this case, the operator controls the three-point linkage (40) by means of the commands provided on said control interface (21). The wireless control device (20) provides transfer of the commands of the operator to the control unit (30) without using any cable, wire, etc. equipment. Said transmitter (22) provides transfer of the commands, entered through the control interface (21), to the receiver (51) in the communication unit (50) and to the control unit (30) from there. Thus, the control unit (30) transforms the commands of the wireless control device (20) into movement in the three-point linkage (40). The control valve (41) in three-point linkage provides oil flow of the hydraulic unit (42) in the direction of the commands of the control unit (30).
By means of the subject matter control system (10), the problems which occur during connection of equipment to the tractor by the operator are eliminated. The operator can provide the connection process in a stand-alone manner and without needing to leave the equipment.
The subject matter control system (10) is essentially connected to at least one position sensor (43) provided on the three-point linkage (40). Said position sensor (43) controls the movements in the three-point linkage (40) according to the commands given, and confirms the correctness of the position. The position sensor (43) transfers the detected position information to the communication unit (50). The information coming from the position sensor (43) are recorded to a memory unit (52) provided in the communication unit (50). Moreover, when fault related to the position is detected, warning can be given by means of at least one warning marker (23). Said warning marker (23) can be positioned on the wireless control device (20) or on the tractor.
In the subject matter control system (10), it is possible that the three-point linkage (40) can be controlled both through the internal control interface (31) and through the control interface (21) in the wireless control device (20). In other words, by means of the subject matter control system (10), remote control can be provided in addition to the operation manner of the three-point linkages (40) used in the present art. Thus, functionality is provided to the present systems.
In a possible embodiment of the present invention, the wireless control device (20) can be a specially designed control device, a key-holder, cellular phone, tablet or computer. Moreover, the wireless control device (20) and the control unit (30) communicate by means of a special matching signal. Thus, the control device (20) can operate only in the tractor where the matched control unit (30) is positioned. Moreover, thanks to said structure of the subject matter control system (10), the subject matter control system (10) can be applied on the three-point linkages, used in the present art, without making any changes. The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
