Definitions
- Radio remote control for issuing commands to a remote-controlled device
- the invention relates to a radio remote control for issuing commands to a remotely controllable device in a wireless way, in which an assignment mode can run before start-up, with a transmitter / receiver unit, a controller and with at least one antenna.
- Remote controls or remote controls particularly for industrial and agricultural devices, have to meet particularly high security requirements.
- the remote controls mostly use a common radio standard, such as. B. Bluetooth, with ranges of up to 100 m depending on the performance class.
- this object is achieved in that after triggering the assignment mode by the user, the radio range of the remote control is reduced to such an extent that communication is only possible with a device located directly on the remote control and a return to the standard range only takes place after the assignment has been completed.
- the solution according to the invention is characterized in that it is particularly simple and is optimally adapted to the actual conditions in industry and agriculture.
- the assignment process can be triggered, for example, by pressing just one key. B. with the remote control located directly on the device, the assignment is made.
- the radio range is reduced by reducing the transmission power.
- the security against undesired "listening" to the transmitted signals is also very high.
- the radio range it is also possible for the radio range to be reduced by reducing the receiver sensitivity, or for the radio range to be reduced by interfering with the antenna function.
- Fig. 1 shows a schematic side view of a device, for. B. a mobile loading crane with remote control attached to it,
- FIG. 2 the docking point of FIG. 1 enlarged and partially sectioned, in a schematic representation
- Fig. 1 shows a device GER, z. B. a mobile loading crane, in general an industrial or agricultural device, which can be operated with a remote control in a wireless way.
- a remote control FEB which can be held in the hand of an operator, is temporarily fixed to a docking point AND of the device GER according to FIG. 1, either only mechanically, with the aid of a suitable holder, or by means of a magnetic holder, which is explained further below.
- the device GER contains a transformer half TRG, which has a core KEG, here a pot core, and a coil WGE or winding.
- the core KEG contains a permanent magnet MAG, which in the present case forms the central core part of the core KEG.
- the magnet can be arranged at other locations, it always being essential that it fulfills its holding function for the FEB remote control.
- a second, user-friendly transformer half TRB is arranged, almost in mirror image, which also has a core KBE and a winding or coil WBE.
- the “open” sides of the two transmitter halves TRB, TRG are arranged directly on an outer wall of the housing of the remote control or of the device GER and are only covered by the respective device wall, which consists of plastic or a non-magnetizable metal.
- the core KBE in the FEB remote control can also contain a permanent magnet, the polarity of certain remote controls can be selected so that in cooperation with certain devices at the docking point, which can be marked accordingly, no tightening but repelling occurs. This means that pairings of remote controls and devices can be displayed as illegal from the start.
- the docking station AND serves as an inductive energy interface at which charging energy can be fed from the device GER into an accumulator AKU of the remote control FEB, which will be explained in the following.
- a power source e.g. B. a vehicle battery with 24 or 48 volt voltage.
- This battery voltage is converted into an alternating voltage by means of a direct voltage / alternating voltage converter GWW and is supplied as such to the coil WEG. If one converts to an alternating voltage with 50 Hz, the FEB remote control is compatible with simple mains-powered chargers. Not shown, but it is clear to the person skilled in the art that the converter GWW is only activated when the remote control is docked, for example with the aid of a contactless switch, such as a reed contact.
- the AC voltage induced in the secondary coil WBE of the transformer TRA is z. B. rectified by means of a rectifier GLR and fed to the battery AKÜ to charge it.
- a rectifier GLR rectified by means of a rectifier GLR and fed to the battery AKÜ to charge it.
- suitable charging and control circuits known to those skilled in the art can be used.
- the charging status and charging process can also be displayed.
- the FEB remote control has an RTX transmitter / receiver unit which interacts with an ANT antenna. Furthermore, a control PRO, z. B. a microprocessor is provided, which can also be part of the transmitter / receiver unit RTX.
- the TAS keys on a keyboard enable commands to be input to the PRO control and, via the transceiver unit RTX and the antenna ANT, to the device GER, which has a corresponding remote station (not shown) for radio communication.
- the GER device also has a RTX transmitter / receiver unit with an ANT antenna, both important functions of the transmitter / receiver unit in the FEB remote control via the PRO controller and in the GER device via the STE controller, such as here in particular the transmission power and the receiver sensitivity can be influenced.
- a known radio standard is expediently used for the wireless communication between remote control FEB and device GER, e.g. B. Bluetooth.
- the invention further provides that at the docking point, which, as explained above, first serves to transfer energy for charging the accumulator, there is also an information Transmission can be performed, which affects the assignment mode.
- This information transfer at the docking station can be done in a variety of ways and some options are explained below.
- FIG. 2 shows the possibility of information transmission via the transformer TRA, signals in the remote control FEB as well as in the device GER being able to be coupled out via a filter FIL, which signals from the control PRO in the remote control FEB and a control STE in can be sent to the device GER via the transformer interface TRA and vice versa.
- FIG. 3 A simple possibility of information transmission in the sense of “recognizing” a remote control is outlined in FIG. 3.
- the coil WBE of the transmitter half in the remote control is bridged by a transistor TRS, possibly in series with a series resistor Rr Control PRO of the FEB remote control can be controlled with a predetermined individual frequency f 0, for example 1 kHz, so that the impedance changes accordingly.
- a predetermined individual frequency f for example 1 kHz
- a remote control FEB If a remote control FEB is docked on the device GER, the battery AKU can be charged immediately. Furthermore, it can only be recognized by a current or impedance measurement on the part of the device that a remote control is available. When measuring e.g. 3, identification is also possible. Furthermore, data such as a key, a PIN etc. can be exchanged via the transformer interface TRA. However, a radio mode can also be initialized, which, for. B. with Bluetooth assigning the radio identifiers of the remote control FEB and device GER. At the same time, an adjustment of the Parameters of the remote control to the type of device to be operated or the transfer of operating parameters to the remote control. To ensure that the data has been completely transferred in the assignment mode, the end and / or the course of the data transfer can be displayed, for example: B. with a display light source ANZ.
- the actual operation of the device GER is preferably carried out by radio using the remote control that is usually held in the hand of an operating person, whereby usually a few input keys TAS on a keypad are sufficient. Several or even just one of these keys can be used with the remote control docked to start the sequence of the assignment mode, so that no complicated entries via alphanumeric keypads are necessary. The data exchange required for the assignment then runs automatically.
- the invention provides for the data required for this to be transmitted by radio, the radio range being reduced to such an extent that radio communication with other units can be excluded.
- the Bluetooth standard is described, for example, in: "LMP Camp tutorial", 3. 1. 2 Authentication, 3. 1. 3 Pairing (freely accessible in the www at http: //203.147 .194.107 / infotooth / tutorial / lmp. Asp) Only when the assignment has been completed will there be a return to the standard range so that the remote control can then be used for its purpose.
- the radio range can be reduced very simply by reducing the transmission power, namely to a minimum power which, when the FEB remote control is docked, is sufficient for data transmission to usually only a few cm. Accidental communication with third-party devices or "eavesdropping" is hardly possible.
- the range can also be reduced by reducing the receiver sensitivity of the GER device, which reduces the risk of interference from other devices. The same applies to a reduction in the range by interfering with the antenna function, in many cases a combination of the measures mentioned can be expedient, in particular a reduction in the transmission power on the one hand and the receiver sensitivity on the other. It should be clear that all measures to reduce the range can be carried out on the part of the remote control and / or the device.
- FIG. 4 For an explanation of a possible initialization process, reference is made to FIG. 4, in which such a process is shown, starting with the docking.
- the radio range is reduced in the next step and then the assignment mode is carried out in a known manner.
- part of the information exchange can also take place via the inductive interface TRA, in particular at the beginning or at the end of the entire assignment process.
- the docking station with its (additional) inductive interface offers the possibility of connecting e.g. B. a notebook or other service device by a service technician.
- a cable connected to the service device can e.g. B. have an "adhesive head", which - like the remote control - contains the supplementary half of the transformer TRA.
