Definitions
- the invention relates to a device for the wireless voltage supply, preferably of sensors arranged in motor vehicle tires, and of the data transmission between the sensors via electronic functional units required for their operation, such as signal processing arrangements and transmitting and receiving devices, on the one hand and remote stations attached to the vehicle.
- DE 101 64488 AI describes a device for transmitting and / or receiving data, tires for a motor vehicle, transmitting and / or receiving device and system for wireless transmission of data, it being provided both the energy supply of the device located in a rotatable part as well as to enable data transmission in any position of the moving part.
- the device is arranged in spatial proximity to a metal belt of a movable part, in particular a motor vehicle tire.
- a transmitting and receiving device and a control device connected to it are also arranged on the vehicle.
- the device arranged in the tire includes an antenna device and an energy store, as well as a data processing device and a sensor system, which are each electrically linked in accordance with the task.
- the data obtained and appropriately processed by means of the sensor system are transmitted wirelessly via the transmitting / receiving unit and the antenna device to the remote station arranged on the vehicle.
- the energy required for this is obtained from the radio field for transmitting the data between the transmitter / receiver units in the tire and on the vehicle using the tire's metal belt. It can be problematic here that the tire belt is designed as a steel belt, since steel belts shield the radio waves used for data transmission and the efficiency of the energy supply is thereby reduced.
- the known solution counteracts this by selecting the transmission power of the radio field so low that the induction of eddy currents with the vectors counteracts the magnetic field strength of the radio field. shielding of the metal belt based on the opposite effect is kept as small as possible and as a result the magnetic field emanating from the radio field penetrates the metal belt. Because of the diffraction of the magnetic field around the metal belt based on the electrical conductivity of the metal belt, there is an energy distribution of the radio wave field along the entire circumference of the tire belt. Energy is extracted from this radio wave field diffracted in this way by the antenna device in that the antenna device is arranged in the immediate vicinity of the tire belt and is capacitively and / or inductively coupled to the tire belt.
- the energy absorbed by the antenna device is fed to an energy store which is designed as a capacitor arrangement.
- an energy store which is designed as a capacitor arrangement.
- the transmitting and receiving device or the control device on the vehicle is designed to detect a standing wave of the radio field formed on the tire belt.
- the frequency of the radio field is set differently from the resonance frequency of the tire, the resonance conditions being obtained from the tire data which are known to the control device on the vehicle.
- an additional antenna in particular in the form of a wire, can be used as the field antenna, which is arranged in the inner tread of the tire.
- the wire can be mounted both in front of and behind the tire belt and can be made available in particular via the construction technology of the tire.
- the additional antenna extracts energy from the radio field and feeds it to the antenna device, whereby the influence of the rim on the electromagnetic field is reduced and, in addition to a speed-independent mode of operation, an improved energy input and interference-free reception are achieved.
- limits are imposed both with regard to the frequency and in particular the transmission power.
- the transferable energy is low and in particular not suitable to be used without additional measures such as accumulation, that is to say the build-up of the charge of a charge storage over time as supply energy in the form of an operating voltage for the energy-consuming components of the device arranged in the tire.
- the object of the invention is therefore to simplify the wireless transmission of electrical energy for voltage generation for the supply of an electrical consumer optionally arranged in or on a rotating device and to reduce the effort required and to link it with the data transmission.
- a first coil connected to a supply device forms the primary winding and a ring conductor forms the secondary winding of a transformer, and a second coil is inductively coupled to the ring conductor, to which an electrical consumer is connected.
- the invention is further developed or advantageously configured by the features of the subclaims.
- the supply device comprises a supply, reception and transmission unit and / or the electrical consumer is designed as an electronic circuit.
- the invention is advantageously embodied in that the electronic circuit comprises a receiving unit, a transmitting unit, a processing and control unit, a storage unit, at least one sensor element and a rectifier and smoothing circuit, and the rectifier and smoothing circuit is connected to the second coil and in particular by the transmission unit being designed as a load modulator.
- the ring conductor consists of flexible material and is coaxial and second coil and the electrical consumer on or in a tire and the supply device and the first coil are arranged stationary.
- the diameter of the ring conductor is larger or smaller than the diameter of the metal belt of the tire and that the supply device with the first coil are arranged in the wheel arch region of a motor vehicle. It is immaterial whether the ring conductor is arranged only outside, only inside or penetrating the metal belt and thus partly outside and partly inside the metal belt of the tire.
- a wheel box unit is connected to the vehicle processing unit per impeller, which has a power supply unit connected to an on-board electrical system, an interface unit connected to a bus system, a control unit, a storage unit, an RF signal generator, a Modulator / demodulator, an amplifier unit and at least one antenna, a transponder module is arranged in or on each tire, which has a circuit board with an electronic circuit to which at least one pressure and / or a temperature sensor, an HF transponder circuit with receiving, Transmitter and signal processing modules and a rectifier and smoothing circuit includes a coupling coil connecting the input terminals of the electronic circuit and encircling an I-core and a U-core magnetically coupled to the I-core as well as one provided with an air inlet and with the Ripe en connected envelope, and each tire has a coaxially arranged and penetrating the U-core and thus inductively coupled with this, made of flexible material ring conductor, the diameter of
- the method used for energy and data transmission is characterized in that the HF carrier signal is emitted via the transmitting antenna of the wheel arch unit, the magnetic alternating field thus generated induces an alternating current flowing in the ring conductor, this alternating current in the U-core crossing the ring conductor and the coupled one I core generates a magnetic flux and the magnetic flux in the coupling coil induces an alternating voltage, which is converted into at least one operating direct voltage by means of the rectifier and smoothing circuit and the data transmission from the transponder module to the wheel arch unit takes place in that the HF carrier signal is emitted via the transmitting antenna of the wheel arch unit, the HF - Carrier signal parallel to the rectifier and smoothing circuit fed to a frequency divider and such an auxiliary carrier signal is generated, the auxiliary carrier signal is modulated with the sensor obtained and processed by means of the signal processing unit low-frequency data signals, by means of the modulated auxiliary carrier signal a switch is controlled which controls the transponder winding with a resistor loaded so that sideband frequency signals modulated
- the wheel arch unit has a first antenna acting as a receiving antenna for modulated data signals and a second antenna acting as a transmitting antenna for an HF carrier signal, the first antenna being arranged in the wheel arch in such a way that it is located in one area minimum field strength of the second antenna and the second antenna is connected to the wheel arch unit by means of a feed line in the form of a twisted cable or a double line.
- This type of connection results in the greatest possible reduction of interference.
- the tire transponder module has a signal processing unit and between the wheel arch unit and the tire transponder module bidirectional data transmission takes place.
- the device according to the invention is distinguished by a mode of operation which is independent of the rotational speed, both in terms of its amount and in its direction. The best results are nevertheless achieved if the antennas of the wheel arch unit are each arranged in the straight rotation plane of the impeller. It goes without saying, however, that the transponder module and the ring conductor are advantageously arranged in the line of symmetry of the tire, in order to ensure constant transmission properties in both right-hand and left-hand installation.
- the invention is explained in more detail in the form of a preferred exemplary embodiment with reference to the drawing.
- the drawing shows in Fig. 1 a transponder module in longitudinal section and Fig.2 an electrical circuit diagram.
- the module contains an electronic circuit E, which is applied to a printed circuit board PCB and consists of a pressure and temperature sensor »an HF transponder circuit with receiving, transmitting and signal processing modules and a rectifier and smoothing circuit.
- the printed circuit board PCB is arranged on an I-core IK, which carries a coil L.
- the coil L is used both for coupling and decoupling during data transmission between the transponder and the wheel arch unit and as a coupling inductor for the energy feed into the transponder and is connected to the electronic circuit E.
- the transponder module is surrounded by a covering VH which is vulcanized on the inside of the tire R.
- the cover VH has an air inlet LE through which the pressure and temperature sensor of the transponder module is exposed to the inner air of the tire. If only a pressure measurement is provided, a membrane area can be provided instead of the air inlet LE.
- a ring conductor RL consisting of flexible conductive material such as copper braid, is embedded coaxially in the tire R and serves as an antenna for the Data transmission as well as a rotating secondary coil of the transformer formed for energy feed acts.
- the ring conductor RL penetrates a U core UK, which is magnetically coupled to the I core IK.
- a wheel arch unit RE is connected to the vehicle electrical system and comprises a power supply unit P, an interface unit INT connected to a bus system LIN, a control and storage unit CON, an RF signal generator GEN, a modulator / demodulator DM and an amplifier unit AMP.
- a reception antenna AE is connected to the amplifier unit AMP, and a transmission antenna AS is connected to the RF signal generator via a double line with cores lying close to one another.
- the receiving antenna AE is arranged in the wheel arch in such a way that it is located in an area of minimum field strength of the transmitting antenna AS. It is also advantageous if both antennas are arranged in the main rotation plane of the tire R.
- the RF carrier signal is emitted by the wheel arch unit RE via the transmitting antenna AS.
- the resulting alternating magnetic field induces an alternating current flowing in the ring conductor RL, which generates a magnetic flux in the U core UK crossing the ring conductor RL and the coupled I core IK.
- the magnetic flux induces an AC voltage in the coupling coil L, which is converted into at least one operating DC voltage UB by means of a rectifier and smoothing circuit GG.
- Most unit RE is carried out by emitting the RF carrier signal via the transmitting antenna AS of the wheel arch unit RE and parallel to the rectifier and smoothing circuit GG a frequency divider, which is part of the electronic circuit E and in particular a receiving, transmitting and signal processing module IC shown here summarized , and in this way an auxiliary carrier signal is generated, the auxiliary carrier signal with low-frequency data signals obtained by means of the sensor and processed by means of the signal processing unit is modulated, a switch is controlled by means of the modulated subcarrier signal, which loads the transponder winding with a resistor, so that sideband frequency signals modulated with the data signal arise, the frequencies of which are spaced apart from integer multiples of the frequency of the subcarrier signal from the frequency of the RF carrier signal, the signal mixture from Transponder T emitted and received by the wheel arch unit RE via the receiving antenna AE.
- a frequency divider which is part of the electronic circuit E and in particular a receiving, transmitting and signal processing module IC shown here summarized
- the modulated subcarrier signals are separated by partial suppression of the carrier signal, amplification and mixing on a non-linear characteristic.
- the subcarrier signal with the subcarrier frequency originally obtained from the HF carrier signal by frequency division is filtered out and demodulated from the large number of modulated subcarrier signals.
- the data signals are then processed and set in the bus system via the interface, so that, for example, a display on a cockpit display is possible.
