    Description


    [0001] The object of the invention is a method and a device for wireless magnetic communication applicable to operation of automation and remote control equipment, in particular in industrial facilities and processes, utilities, at commercial premises and in households.

    [0002] There exist many methods of wireless communication which use the propagation of electromagnetic waves, which waves are then converted into electrical spikes that allow one to control devices using microprocessor controllers.

    [0003] A system and method for transmitting code using a short-range magnetic field is known from the application documents US2014273826. A secure system wirelessly transmits, via a magnetic field transmitter, an access code to a handheld wireless communication device as a sequence of polarities of a short-range magnetic field. The wireless communication device senses the code from the sequence of polarities. The code provides access to the secure system. The handheld wireless communication device can wirelessly transmit the code received from the short-range magnetic field and identification information to the secure system to receive access to the secure system. The access is personalized based on at least the identification information and is maintained or validated when the handheld wireless communication device is within range of the short-range magnetic field. The method enables obtaining a secure connection with devices such as cellular phone, smartphone or walkie-talkie. US 2013/0244700 A1 discloses magnetic field sensors of mobile devices used for providing the mobile devices with information at a locally extremely restricted area in that, specifically, a magnetic field modulated with the information is locally generated at this position by an information signal generator.

    [0004] A wireless magnetic communication method consisting in the processing of information encrypted in the transmitter using the magnetic field and decrypted by the receiver with proximity magnetic sensors is characterised in that the transmitter is equipped with a magnetic system with a planarly shaped configuration of magnetic elements. The transmitter is placed against the receiver which one couples to the first microprocessor controller. Then, via the receiver's magnetic sensors, the configuration of the magnetic field generated by the magnetic elements of the transmitter by is recreated, and next, using the first microprocessor controller one compares such configuration with the pattern implemented therein. Subsequently, according to the software implemented in the first microprocessor controller, further actions corresponding with that pattern are launched.

    [0005] Permanent magnets are used as magnetic elements with a favourable effect.

    [0006] The magnetic system is embedded astatically in a permanent element of the transmitter with a favourable effect.

    [0007] Time varying magnetic field generators are used as magnetic elements with a favourable effect.

    [0008] The transmitter is equipped with a second microprocessor controller with a favourable effect.

    [0009] Wireless magnetic communication device comprising a receiver equipped with proximity magnetic sensors and a transmitter of information encrypted using a magnetic field is characterised in that the transmitter is equipped with a magnetic system with a planarly shaped configuration of magnetic elements which are permanently embedded therein. The receiver has a system of magnetic sensors which is configured in a form constituting the mapping of the magnetic system. The system of magnetic sensors is coupled to the first microprocessor controller with the implemented configuration pattern of magnetic elements of the magnetic field and the software comparing the configuration of the magnetic field generated by the magnetic elements with that pattern and launching further actions corresponding with that pattern.

    [0010] Permanent magnets are used as magnetic elements with a favourable effect.

    [0011] The magnetic system is embedded astatically in a permanent element of the transmitter with a favourable effect.

    [0012] Time varying magnetic field generators are used as magnetic elements with a favourable effect.

    [0013] The transmitter is equipped with a second microprocessor controller with a favourable effect.

    [0014] The transmitter and the receiver have been equipped with location markers with a favourable effect.

    [0015] On or below the transmitter's surface, there is mounted a permanent magnets system of a particular configuration or a system generating varying magnetic fields in accordance with a specified scheme, built with the use of elements that generate small magnetic fields. The transmitter is placed against the surface of the receiver in which a matrix of magnetic field sensors coupled to the first microprocessor controller is located.

    [0016] With the use of the magnetic field sensors contained in the receiver, a permanent or varying magnetic field configuration generated in the transmitter is recreated, and next, using the microprocessor controller, such configuration is compared with the pattern implemented therein. Compliance with the pattern initiates further actions corresponding with that pattern, in accordance with the software implemented in the controller. Incompliance with the pattern does not result in taking actions, or triggers actions appropriate to such situation, i.e. to an unauthorized communication attempt.

    [0017] Wireless magnetic communication method, according to the invention, offers security, reliability, energy efficiency and low cost of communication. Furthermore, all active elements taking part in the communication can be hidden inside the casing of both the transmitter and receiver. This makes the communication system, according to the invention, aesthetic and discrete.

    [0018] The invention is more thoroughly explained in the example embodiments, which do not limit its scope, and in the illustration where fig. 1 shows schematically a device fitted with a magnetic system with permanent magnets in axonometric view, fig. 2 shows schematically, in axonometric view, a device with a magnetic system astatically embedded in the transmitter, and fig. 3 shows schematically, in axonometric view, a device with time varying magnetic field generators.

    Example I



    [0019] Receiver 2 has a matrix 8 made in the form of a dial, where in the place of each hour a magnetic field sensor 5 which senses magnetic field is fitted. Matrix 8 of magnetic sensors 5 is coupled to the first microprocessor controller 7. The transmitter 1 has a magnetic system 3 also shaped in accordance with the configuration of the magnetic sensors 5 on the matrix 8. In places corresponding to twelve, five and eight o'clock there have been fitted permanent magnets 4. Once placing the transmitter 1 against the receiver 2, the magnetic field sensors 5 sense the magnetic field generated by the magmatic elements 4 of the transmitter 1 and send this information to the first microprocessor controller 7. For the purpose of appropriate matching, the transmitter 1 and the receiver 2 are equipped with location markers 6. In the first microprocessor controller 7 a comparison is conducted between the configuration of the magnetic field generated by the magnetic elements 4 and the pattern, and then the dedicated software launches an action ascribed to a particular configuration, e.g. "switch the device to a different mode". A failure to identify the configuration does not result in starting an action, or, alternatively, identification of a configuration which is incompliant with the configuration patterns may result in starting a special action, pertaining to the detected unauthorized communication attempt.

    Example II



    [0020] The device is built as in example I, whereas the magnetic system 3 is mounted rotatably against the surface of the permanent element of the transmitter 1. During the rotation of the magnetic system 3 for a given time at a given angular velocity or a sequence of such rotations with various rotation times and velocities, a time varying magnetic field is generated, which enables the transmission of more complicated massages to the receiver 2.

    Example III



    [0021] The device is built as in example I, whereas the magnetic system 3 is equipped with elements generating time varying magnetic fields 4 controlled using the second controller 9 fitted in the transmitter 1, which enables transmission of more complicated massages addressed to the receiver 2.
