DETAILED DESCRIPTION

[0028] The disclosure is now described with respect to its particular embodiments, with reference to the accompanying figures. In the following figures and description, equal or corresponding parts are marked with equal reference numbers.

[0029] The figures are schematic and their dimensions and proportions are exemplary, as they are only intended to describe the disclosure in order to facilitate understanding and do not impose any limitations beyond those defined by the appended claims.

[0030] The present disclosure deals with a system that uses CAN (Controller Area Network) serial communication bus, namely CAN bus, and wireless communication modules to transmit an instruction from a user to a peripheral device 16 in a row unit.

[0031] FIG. 1 illustrates a general diagram of an embodiment of the disclosure that shows the communication relationship between the elements of the communication and control system 1 of peripheral equipment 16 of agricultural implements. More specifically, FIG. 1 shows that the human-machine interface 2 and the control module 4 have a communication established through a first communication means 3, the control module 4 and the remote module 7 have communication established through a second communication means 6 and the remote module 7 establishes communication with the peripheral device 16 through a third communication means 9.

[0032] In particular, the third communication means 9 of the present disclosure provides for communication between a remote module 7 and a plurality of peripheral devices 16, whereby the peripheral devices 16 can be of different types and with different functions. So that a remote module 7 can interact with one of the peripheral devices 16 without interfering with the operation of the other peripheral devices 16.

[0033] FIG. 2 illustrates a general diagram of another embodiment of the disclosure, in which the control module 4 has communication established through the second communication means 6 with more than one remote module 7 and each remote module 7 is in communication with their respective peripheral devices 16 via the third communication means 9.

[0034] FIG. 3 illustrates a detailed diagram of an embodiment of the disclosure in which the first communication means 3 uses an ISOBUS, the second communication means 6 is a radio frequency wireless means and the third communication means 9 uses a CAN bus.

[0035] More specifically, in the embodiment of FIG. 3, the first communication means 3 has a first transceiver 10 at the human-machine interface 2 communicating via ISOBUS with a second transceiver 11 on the control module 4. As an alternative to the ISOBUS standard, the first communication means 3 can use CAN-BUS or other proprietary protocols.

[0036] In FIG. 3 it can also be seen that the Control Module 4 includes a first processing means 5 and a third transceiver 12. The third transceiver 12 is part of the second communication means 6 together with the fourth transceiver 13 included in the remote module 7. In this embodiment, the control module 4 interprets the ISOBUS message received by the second transceiver 11, processes the received ISOBUS message and generates a new command message that is sent by the third transceiver 12 wirelessly to the remote module 7 through the fourth transceiver 13.

[0037] Still in the embodiment of FIG. 3 and in more detail in FIG. 4, the remote module 7 includes a second processing means 8, a fifth transceiver 14 and a dedicated hardware for signal communication 17.

[0038] The fifth transceiver 14 is part of the third communication means 9 and communicates with a sixth transceiver 15 on each of the peripheral devices 16 of the plurality of peripheral devices 16 that can be used simultaneously in the system 1 of the present disclosure. The third communication means 9 is used when the peripheral device 16 operates by message 18 such as, for example, a smart actuator 22, such as a CAN engine, or a smart sensor 23, such as a CAN sensor, also known as “smart devices”.

[0039] The dedicated hardware of the remote module 7 is used to communicate with peripheral devices 16 that operate by signals. More specifically by way of example, an actuator 24, such as a Hall motor, which operates by receiving a control signal 17a from dedicated hardware 21 or a sensor 25 that sends a monitoring signal 17b to dedicated hardware 21.

[0040] A person skilled in the art will readily appreciate that the fifth transceiver 14 and the dedicated hardware 21 are described together as an example in this embodiment of the disclosure, but do not necessarily work together, only the fifth transceiver 14 or the dedicated hardware 21 can be used without prejudice to the operation of the communication and control system 1. Likewise, the communication and control system 1 of the present disclosure allows the use of both types of communication simultaneously without one interfering in the operation of the other, with the fifth transceiver 14 being used when the peripheral device 16 operates by message 18 and the dedicated hardware 21 is used when the peripheral device 16 operates with a control or monitoring signal 17.

[0041] FIG. 4 still illustrates some examples of smart devices that can use the third communication means 9, being a smart seed meter 22, a conveyor belt 26, a depth regulator 27 and a smart seeds sensor 23, among other agricultural devices.

[0042] In addition, the system 1 of the present disclosure advantageously allows the inclusion of new peripheral devices 16 not foreseen during the design and manufacture of the row unit, simply installing the new peripheral device 16 and starting communication with a remote module 7 via the third communication means 9. Unlike what is known in the prior art where only one peripheral device (previously foreseen) is installed per module, the system of the present disclosure allows a new peripheral device 16 to be included in the system taking advantage of a remote module 7 already installed in the row unit, as can be seen in the comparison of FIG. 5.

[0043] The present disclosure also provides a method of communication and control of peripheral devices 16 applied in agricultural implements, as illustrated in FIG. 6, in which: a user enters an instruction into a human-machine interface 2, which processes the instruction; and generates a message, preferably an ISOBUS message; and sends the message to a control module 4; the control module 4 processes the message to interpret the instruction and generate a wireless command message; the message is sent from the control module 4 to a remote module 7 by means of wireless communication; then the remote module 7 receives the wireless message, processes the message to interpret the instruction; and if the instruction is intended for a smart peripheral device, a message is generated, preferably CAN, and sent to the peripheral device; or if the instruction is intended for a simple control peripheral device, such as a Hall motor, a control signal is generated and sent to the peripheral device; or if the instruction is intended for a simple monitoring peripheral device, such as a seed sensor, a monitoring signal is received which is processed in the remote module 7.

[0044] Thus, based on its unique characteristics, it is noted that the present disclosure presents advantages and overcomes the drawbacks of prior art.

[0045] While the disclosure has been specifically described with respect to particular embodiments, it is to be understood that variations and modifications will be apparent to those skilled in the art and may be made without departing from the scope of protection of the present disclosure. Consequently, the scope of protection is not limited to the described embodiments, but is limited only by the appended claims, the scope of which must include all equivalents.
