Definitions
- the invention relates to a remote control device for controlling at least one function of access devices.
- Radio remote control devices for controlling access devices for example for controlling a garage door drive, are known, which have a transmitter and a receiver, the receiver being arranged inside the garage and activating the drive for the garage door.
- the user has a transmitter which transmits coded signals, identification data being contained in the coded signal.
- the receiver decodes the respective transmission signal and compares the identification data with identification data stored in a storage device. If the identification data match, the receiver controls the drive of the garage door to actuate it.
- the transmitter is usually designed to be mobile, for example it is stored in a vehicle or installed directly so that the user can operate the transmitter at any time when he wants to drive his vehicle into or out of his garage.
- the transmitter is to be installed in the vehicle, installation measures must be taken retrospectively and it is not possible for the vehicle manufacturer to provide a transmitter in a vehicle from the outset, since the transmitter is assigned to the receiver and the garage door operator controlled by the receiver and the The manufacturer of the vehicle does not know whether and which garage door operator the user wants to install or has installed in his garage.
- a remote control device for controlling at least one function of access devices, which has several types of transmitters and one type, i.e. a uniform
- the receiver controls the access device and the transmitters of the respective type have a system identification word assigned to the type and different serial numbers, for example each type is assigned to a manufacturer.
- the single recipient ie the one type von Receiver has stored the different system identification words of the different types of transmitters, for example in a microcontroller, so that the transmission signal can be understood by the receiver from any type of transmitter.
- This remote control device it is possible to design a uniform microcontroller for the receiver with the plurality of system identification words and to produce it in large numbers.
- the transmitters are equipped with the manufacturer-specific system identification word. In order to obtain equal access for the different types of transmitters, an agreement must be made regarding the serial numbers of the transmitters of different types to be assigned.
- areas of serial numbers are stored in the receiver, each area being assigned to a system identification word, ie a type of transmitter.
- a system identification word ie a type of transmitter.
- a universal transmitter ie a further type of transmitter can be provided, which has a different system identification word to the other types of transmitters, the serial number of which however, are unrestricted.
- a universal transmitter for example in automobiles from the automobile manufacturer, can be installed from the start.
- a change or roll code is used to encode and decode the transmission signals to increase security, so that the transmission signal changes each time the transmitter is actuated.
- the transmitter supplies current synchronization information coded in the transmission signal, which is compared in the receiver.
- tolerance windows are specified with regard to the evaluation, so that in the event of a desynchronization due to an actuation of the transmitter outside the reception area of the receiver, actuation of the access device is nevertheless possible.
- the remote control system comprises a receiver 10, which is referred to as a universal receiver, and several types of transmitters 1 to 5, wherein the transmitters 2 to 5 can be manufacturer-specific.
- the transmitters 2 to 5 each comprise a memory device in which a system identification word that is specific to the respective type of transmitter and a serial number that each transmitter of a type of Stations 2 to 5 is assigned, is saved. Furthermore, each transmitter contains a processing unit or an encoder which contains an algorithm which is known per se, a transmission signal being generated using the system identification word and the respective serial numbers and possibly further information stored in the storage device or contained in the encoder Receiver 10 is transmitted.
- each type of transmitter 2 to 5 is assigned a serial number range, which is shown in the figure for transmitter type 2, for example with 1 to 999999.
- the serial numbers of different transmitters of one transmitter type can be assigned within these areas.
- the receiver 10 likewise has a memory device and a processing unit or a decoder, which can be designed as a microcontroller.
- the system identification words SI 2 to SI 5 of the individual transmitter types 2 to 5 are stored in the memory device or in the microcontroller, and the serial number range assigned to the respective transmitter types 2 to 5 and the system identification words are also stored.
- the receiver also contains the algorithm or the mathematical basis with which the transmitters 2 to 5 code the transmission signals.
- the transmitter and the receiver of the remote control device can control different functions, for example when using the remote control device for access to a garage or for another entrance control device with one
- the transmitter and receiver can be used to control the opening and closing of the garage door, the lighting and, for example, the activation or deactivation of an alarm system.
- the functions are programmed on one or more buttons of the respective transmitter, with corresponding buttons or switches being provided on the receiver 10. If several functions are controlled by the transmitter, the information about the function is included in the transmission signal and transmitted to the receiver.
- the coding process is initialized, i.e. the permanently stored and non-readable system identification word and the serial number of the respective transmitter control the specified algorithm, which, as a transfer function via the corresponding processing unit, e.g. 64 bit long code word delivers.
- This includes, among other things, encrypted information about the desired function to be carried out, the synchronization status of the transmitter and unencrypted the serial number of the transmitter.
- Said transmitted transmission signal or code word arrives at the receiver 10 by first checking whether the serial number was stored in the memory during a previous initialization or synchronization and is present. If this is not the case, the transmitted information is ignored and the sender is treated as unauthorized. Once the serial number has been stored, all the necessary information, namely the system identification word, serial number and algorithm, is available to decrypt the transmitted signal. If the system identification word does not match, no decryption can be carried out and the transmitter is again marked as recognized without authorization. If the identification word is present in the receiver, the signal is decoded and decrypted and the receiver checks whether the serial number of the transmitter falls within the range assigned to the system identification word. If this is not the case, the function is not executed. If all values match, the desired control is carried out.
- Rollcode used by which the coding with each coding process, i.e. is changed each time the transmitter button is pressed. This makes it impossible to listen to a code once it has been transmitted and then to play it back through an unauthorized transmitter due to the constant changing of the code.
- an internal counter can be provided in the receiver and in the transmitter, the algorithm using the counter reading that is incorporated into the transmission signal.
- other measures for the production of the change code can be provided.
- the receiver In order for the transmitter and receiver to match the switch code, the receiver must be synchronized or taught in to the respective transmitter. This synchronization or teaching can only be carried out successfully if the same system identification word is stored in the transmitter and in the receiver.
- a voting button or a voting switch for the desired function To synchronize or to teach in a receiver, a voting button or a voting switch for the desired function must be pressed on it.
- the receiver 10 is thus brought into the synchronization or teach-in mode. Then press the button or the input element on the transmitter that performs this function should be assigned.
- the transmitter then sends the coded transmission signal described above, which transmits all information to the receiver, which in synchronization mode now stores the serial number, the information about the pressed key and the synchronization information of the transmitter in the memory.
- the system between the transmitter and the receiver does not get out of step, because after another actuation in the reception area, ie after transmission of the transmitted transmission signal to the receiver, the decryption provides the current synchronization information of the transmitter, which however does not differ in the desired way from the stored information, so that the receiver would not control the control device in operative connection with it.
- a so-called tolerance window is provided in the receiver for the deviations between the synchronization information stored in the receiver and the current synchronization information transmitted by the transmitter. If the synchronization information is within the specific predetermined tolerance window, the desired function is nevertheless carried out.
- a second tolerance window can be stored in the receiver, which is larger than the first tolerance window.
- the current synchronized information is temporarily stored and the desired function is not carried out.
- the impression arises that he did not press the send button properly and he normally presses it a second time.
- Now all information is transmitted and decrypted again and the comparison of the synchronization information provides the expected result and the selected function is carried out.
- the current information is saved again and the transmitter and receiver run synchronously again.
- the small tolerance window includes, for example, deviations for 16 operations outside of the reception area and the larger deviations from much more operations. If the key was pressed more than the actuations of the second larger tolerance window, the system cannot synchronize and no more functions are carried out. In this case, a complete resynchronization must be carried out using the tuning buttons.
- the radio remote control system may include a universal transmitter 10
- transmitter type 1 being assigned to the universal transmitter.
- SI 1 system identification word which differs from the others and which is also stored in the receiver 10. So that this transmitter 1 can be used as a universal transmitter, no serial number range is assigned to it, but the serial numbers can be assigned without restriction. The transmitter can then address all receivers of type 10 receivers.
- the stored serial numbers in the receiver can be deleted, whereby any voting button on the receiver is pressed continuously for a longer period. All serial numbers of all transmitters that have ever been synchronized are stored in the memory.
- the memories contained in the receiver are non-volatile, i.e. if the power supply fails, the information contained therein is not lost. All possible operating states of the receiver mentioned above are shown on a display.
- the transmitter is equipped with a receiving unit and the receiver with a transmitting unit.
- the receiver can give feedback, for example, whether the desired function has been carried out. This option is particularly important when activating an alarm system via radio, since it can be used to identify whether it has actually been initialized.
- other signals such as a signal via the structure of the transmission path, synchronization signals or other tuning signals can also be transmitted via the bidirectional transmission path.
- radio transmission was described, for example, at a frequency of 433 MHz.
- other transmission paths that fulfill the function are conceivable.
