Definitions

  • the present invention relates in a first aspect to a device for contactless energy and data transmission according to the preamble of claim 1.
  • the invention in a second aspect, relates to a method for contactless energy and data transmission between the primary and secondary units.
  • Generic devices have a primary unit with a primary inductance and a secondary unit with a secondary inductance.
  • the secondary unit is set up for connecting, for supplying and / or for controlling at least one terminal.
  • the primary unit and the secondary unit are at least temporarily positioned relative to one another such that a transformer coupling path is formed between the primary inductance and the secondary inductance.
  • the primary unit for contactless transmission of energy to the secondary unit is set up via the transformer coupling path and the secondary unit is provided for supplying the terminals by means of the energy received via the transformer coupling path.
  • Such devices are used when sensors are to be supplied and controlled, which are located on movable, such as rotatable objects and therefore can not be supplied and queried by means of a cable connection. Examples of this are sensors on pressure rollers or on moving elements in a high-bay warehouse.
  • sensors are supplied, for example via a radio link with information.
  • similar inductive couplings are used.
  • the primary unit and the secondary unit can be considered as parts of the sensor, but also as a separate device, which is responsible for the contactless transmission of energy and data.
  • two separate channels are provided for the transmission of energy and the transmission of data.
  • Such devices are made, for example DE 100 12 981 A1 or DE 102 00 488 B4 known.
  • the data is modulated onto the energy transfer and subsequently evaluated in the sensor or the secondary unit.
  • the problem here is to send information from the sensor back to the power supply or the primary unit, so that they can forward the data to a process control.
  • a sensor with such a frequency modulation of the energy transfer is, for example, in DE 10 2004 015 771 B4 described. Similar energy and data transmissions are also in other non-contact systems such as access control from the DE 44 21 526 C1 and in transmission systems from the US 5 345 231 A known.
  • Generic devices use a transformer coupling between the primary inductance and the secondary inductor instead of a radio link between the primary unit and the secondary unit.
  • many devices are already being used, which communicate with each other by radio communicate, whereby the radio bands are largely occupied and there are problems with the signal quality in the multiple use of these bands.
  • radio transmissions are relatively susceptible to interference, as compared to a transformatory transmission, for example by other electromagnetic fields generated by electrical devices.
  • Under transformer coupling is particularly the direct coupling of two inductors, such as coils to understand. In this case, an air gap of a few centimeters or less is bridged between the two coils.
  • the two coils are aligned coaxially with each other.
  • the aim of positioning the coils relative to one another is to achieve a particularly high coupling factor between the primary inductance and the secondary inductance.
  • a coupling factor is close to or equal to 1. This can be achieved for example by the frontal positioning of the two coils to each other.
  • as many field lines as possible of the magnetic field of the primary coil should pass through the secondary coil.
  • the magnetic field can be additionally amplified or influenced by ferromagnetic cores in the coils.
  • the primary unit has means for interrupting the transmission of energy via the transformer coupling path in energy-saving pauses and the secondary unit has means for detecting the energy end pauses.
  • a device for transferring energy and data between two devices is off US 5 515 399 A , which discloses the preamble of claims 1 and 8, known.
  • For contactless transmission here is a transformer.
  • US 5 548 282 A describes a transfer of energy and data to an electronic screen to display prices on a shelf.
  • An object of the invention is to provide a non-contact power and data transmission apparatus which enables efficient power transmission while still allowing easy execution of the secondary unit. Furthermore, the data transmission should be robust against external interference signals.
  • the object is achieved by a method for contactless energy and data transmission according to claim 8.
  • the transmission of data from the secondary unit to the primary unit is performed in power transmission pauses.
  • the data transmission that is, for example, the pulse shape or the coding of the data
  • the corresponding electronics for sending the signals in the secondary unit can be easily designed. This is of particular interest because the secondary unit should only be supplied with energy via the transformer coupling path and thus should be designed to save energy.
  • the secondary unit detects the energy-saving pauses and transmits data to the primary unit as a result of the detection of an energy-saving pause.
  • the detection of the energy-saving pause ensures that data is not transmitted by mistake even when energy is sent via the transformer coupling link, which, in principle, can take place, for example, in a transmission sequence or transmission rights determined only by timing. Moreover, this does not require synchronization of two timers on the primary unit and the secondary unit.
  • the primary inductance is excited by a resonant circuit or forms itself a part of this resonant circuit. In this case, it is preferable if it forms a part of the resonant circuit itself, since in this way no further components have to be provided on the primary unit.
  • a resonant circuit e.g. a parallel or a serial resonant circuit can be used.
  • the secondary unit In addition to the means provided in the secondary unit for transmitting data to the primary unit means for transmitting information to the secondary unit are provided in the primary unit. This transmission can take place, for example, by varying the length of the energy-pauses and / or the length of energy transmission phases.
  • Bidirectional communication can take place over the same channel over which power is transmitted.
  • Data transmitted from the primary unit to the secondary unit may be, for example, instructions for switching operations for actuators connected to the secondary unit, initialization instructions, or configuration data for the secondary unit or devices connected to it, such as sensors or actuators.
  • Data sent from the secondary unit to the primary unit may relate to switching states or other state variables of the connected terminals.
  • the resonant circuit is no longer supplied with energy, so that it decays slowly.
  • the transmitted energy slowly decreases continuously.
  • energy is no longer transmitted as soon as energy interruption via the transformer coupling path, that is, as soon as possible can be started with the actual energy-saving break to accordingly quickly start again with the retransmission of energy.
  • This is achieved by the accelerated degradation of the residual energy in the primary inductance. This degradation can be achieved for example by a transistor path, which is in series with the primary inductance.
  • the additional use of a resistor, which absorbs energy also has an accelerating effect.
  • a voltage is monitored via the primary inductance. If this voltage rises above a previously determined threshold in an energy-saving pause, this is interpreted as a data signal and corresponding information forwarded to downstream processing.
  • a current through the primary inductance is measured.
  • This can be done for example by a transformer, which can be designed as a printed circuit transformer.
  • the measurement signal supplied by the transformer is proportional to the current in the primary inductance.
  • the load can be determined, which is represented by the secondary unit and the connected terminals. By determining the load, it is possible to regulate the resonant circuit current so that it does not become unduly high at low loads. In this case, the excitation of the resonant circuit can be interrupted, for example, until the current flow is again in a desired range.
  • the energy-saving pauses at the secondary unit can be arbitrarily determined.
  • the secondary unit has means for measuring a voltage across the secondary inductance. If this voltage drops, it is concluded that there is a start of an energy-saving break, whereby the transmission of the data from the secondary unit in the direction of the primary unit is initiated via the transformer coupling path.
  • the secondary unit Since the energy transfer is interrupted in energy-saving pauses, it is advantageous if the secondary unit has a storage capacity for buffering the energy. As a result, the supply of the secondary unit as well as the connected terminals can be ensured during an energy-saving break. In this context, it is preferred if more energy is transmitted via the transformer coupling path during the time in which energy is transmitted than is consumed at the time of energy transfer from the secondary unit and the connected terminals.
  • the energy storage can be realized by a capacitor, which is preceded by a rectifier.
  • sensors or actuators can be connected.
  • other consumers such as incandescent lamps
  • actuators are electrical valves.
  • the sensors can be any type of sensor for detecting a measured variable or for detecting objects or objects.
  • the present invention for sensors in the industrial sector, for example, inductive, capacitive or optical sensors, temperature or pressure sensors, are used, each having a corresponding sensor element.
  • a sensor element may in principle be any element which is suitable for detecting a physical quantity.
  • the sensor element may be a coil or a resonant circuit of an inductive proximity switch, a photodetector of an optical sensor, a capacitive probe, or a thermocouple.
  • An inventive method for contactless energy and data transmission can be performed with a primary unit and a secondary unit, each having an inductance.
  • the primary unit and the secondary unit are at least temporarily positioned so that between the primary inductance and the secondary inductance, a transformer coupling path is formed.
  • at least temporarily energy for supplying the secondary unit and connectable terminals via the transformer coupling path from the primary unit to the secondary unit is transmitted contactless.
  • the energy transfer from the primary unit to the secondary unit is at least temporarily interrupted. This interruption of energy transfer is referred to as an energy-saving break.
  • the secondary unit in turn detects such an energy-saving pause and, in the energy-saving pause, transmits data via the transformer coupling path to the primary unit.
  • no signals are transmitted from the secondary unit to the primary unit in the energy-saving pauses.
  • data is transferred from the primary unit to the secondary unit.
  • the data can be mapped, for example, by varying the length of the energy-saving pause.
  • Another possibility is to use different data Expressing intervals of multiple energy silence intervals to each other or to use both types of data encoding.
  • both a transmission of signals in the energy-saving pauses from the secondary unit to the primary unit takes place, as well as a transmission of data from the primary unit to the secondary unit.
  • a single bidirectional channel is used for both the data and the energy transfer.
  • Data transmitted from the primary unit to the secondary unit may be, for example, instructions for switching actuators connected to the secondary unit, initialization instructions or configuration data for the secondary unit or for connected devices such as sensors or actuators.
  • Data sent from the secondary unit to the primary unit may be, for example, switching states or other state variables of the connected terminals.
  • An inventive method can be carried out for power and data transmission between a fixed primary unit and a movable secondary unit. This may be the case, for example, with pressure rollers in which the secondary unit is positioned in or near the axis.
  • Another example is a high-bay warehouse in which the goods in the warehouse are automatically moved out of the shelves and into the shelves by means of loading and unloading equipment.
  • the secondary unit can then be provided, for example, on a loading and unloading device and the primary unit fixed to a previously defined point to which the loading and unloading returns to the idle state.
  • the primary inductance for energy transfer is excited with an alternating current.
  • the primary inductance itself can represent a part of a resonant or resonant circuit or be excited by it.
  • the control of the resonant circuit is preferably by means of a current intensity measurement, a control and a transistor bridge regulated.
  • the current intensity measurement can be carried out, for example, via a transformer whose measuring signal is proportional to the current intensity.
  • the measuring signals from the transformer are amplified with a phase correction and passed on to the drive.
  • the control controls the transistor bridge or its driver circuit such that the transistor bridge always switches in the vicinity of the zero crossing of the resonant circuit current and thus the resonant circuit is additionally excited. As a result, switching losses are avoided, and it is, so to speak, a square wave voltage on the resonant circuit. In the control, a review of the current resonant circuit current can be made to suspend the excitation at possibly too high currents.
  • the residual energy is dissipated accelerated in the primary inductance. This can be done for example via the control, which then phase-inverted supplies the primary inductance or the resonant circuit with power, so that the vibration is damped. Alternatively, this can also be done by a series transistor path, e.g. made of FETs and / or resistors.
  • the secondary inductance is tuned to the primary inductance or its oscillation frequency.
  • this requires appropriate tuning between the two inductors.
  • drifts of the natural frequencies e.g. due to aging or temperature changes. Therefore, it is preferred that when using the transformer coupling path according to the invention, the secondary inductance is operated uncoordinated. This means that no effort is made to match them to the resonant frequency of the primary inductor or resonant circuit in the primary unit.
  • One way to detect the energy end pauses by the secondary unit is to monitor the voltage across the secondary inductance. If this voltage drops, then the beginning of an energy-saving break is concluded.
  • the data transmission from the secondary unit to the primary unit in an energy-saving break can basically be arbitrary. But it is especially easy when the secondary inductance is supplied with current for transmitting the data, and then this current flow through the secondary inductance is aborted, in particular abruptly. As a result, a pulse is triggered, which is transmitted to the primary inductance via the transformer coupling path and can be detected in the primary unit as a voltage pulse.
  • the data that is transmitted from the secondary unit to the primary unit can be, for example, information about measuring signals of the wound sensors. It is also possible to transmit information about the current switching states of connected actuators. In doing so, it has proven to be advantageous if these data are subjected to a source or channel coding before or during the transmission, in order to reduce the susceptibility to transmission errors. Similarly, the provision of a checksum is possible to detect transmission errors.
  • Fig. 1 the current over the time in the primary inductance 4 of the primary unit 2 is shown.
  • the primary inductance 4 or the resonant circuit is excited by the control of the primary unit 2 with current, so that it is set in oscillation. That is, from the time t 0 and before it to the time t 1 41 energy is transmitted to the secondary inductance 3 in a first energy transfer interval.

Furthermore, the current measured by the current and voltage sensor 16 is used to control the current in the coil 4 to ensure that the resonant circuit current is not inadmissible gets high. The control is carried out by the control device 10 such that when the current through the coil 4 is too high, the resonant circuit is no longer excited.
