Definitions
- the invention relates to a remote control device for Control of at least one function of access devices.
- radio remote control devices for controlling Access devices e.g. to control a garage door operator known, the one transmitter and one Have recipients, with the recipient inside the garage is arranged and the drive for the garage door activated.
- the user owns a transmitter which sends coded signals, in which coded Signal identification data are included.
- the receiver decodes the respective transmission signal and compares the identification data with in one Storage device stored identification data. If the identification data match the receiver controls the drive of the garage door its actuation.
- the transmitter is usually mobile, for example, it is stored in a vehicle or built in directly so that the user at all times can operate the transmitter if he with his Wants to drive the vehicle into or out of its garage.
- the transmitter is to be installed in the vehicle installation measures must be taken retrospectively and it is not possible from the outset a transmitter in one To provide the vehicle by the vehicle manufacturer, because the sender to the receiver and the by the Receiver-controlled garage door operator assigned and the manufacturer of the vehicle does not know whether and which garage door operator the user has in his Wants to install or has installed a garage.
- From US-A-5 686 904 is a self-learning security system with an encoder and a decoder known in which the encoder including information a saved user key using a stored non-linear Encoding algorithm to generate a value that is transmitted to the decoder.
- the User key on a unique manufacturer defined master key (system identification word) and a serial number.
- the decoder decodes the value using the master key and of the algorithm stored in the decoder.
- Remote control device for controlling at least one Function of access devices to create the with regard to the different manufacturers of access devices is manufacturer-independent, and different access devices for the users enable equal access.
- a remote control device to control at least one function of Access devices provided several types of transmitters and a kind, i.e. a uniform
- the receiver has, the receiver being the access device controls and where the transmitters of the respective Type a system identification word assigned to the type and have different serial numbers, for example, each type assigned to a manufacturer is.
- the single recipient i.e. the one kind von Receiver has the different system identification words of the different types of transmitters for example stored in a microcontroller, so the broadcast signal from any type of transmitter can be understood by the recipient.
- This Remote control device it is possible for the receiver a single microcontroller with the majority design system identification words and to produce this in large numbers.
- the transmitters with the manufacturer-specific system identification word fitted.
- a universal transmitter i.e. another type of transmitter may be provided, the one different system identification word to the other types of transmitters, their serial numbers however, are unrestricted.
- a universal transmitter e.g. in automobiles from automobile manufacturers be installed from the start.
- a bill of exchange or Roll code for coding and decoding the transmission signals used so that the transmission signal at changes every time the transmitter is pressed.
- current synchronization information encoded in Transmitted signal delivered, compared in the receiver becomes.
- tolerance window regarding the evaluation with a desynchronization due to a Operation of the transmitter outside the reception area the receiver nevertheless actuates the access device is made possible.
- the remote control system includes a receiver 10 which is designated as a universal recipient, and several Types of transmitters 1 to 5, with transmitters 2 to 5 can be manufacturer-specific.
- the transmitters 2 to 5 each comprise a storage device, in the a system identification word that is specific to the type of transmitter, and a serial number assigned to each sender of a kind of Assigned to stations 2 to 5 is saved.
- each transmitter contains a processing unit or an encoder, the algorithm known per se contains, using the system identification word and the respective serial numbers and possibly further ones in the storage device stored or contained in the encoder Information a transmission signal is generated which is transmitted to the receiver 10.
- the receiver 10 also has a storage device and a processing unit or a decoder to be trained as a microcontroller can.
- the system identification words SI 2 to SI 5 of each Channel types 2 to 5 are stored and are also the respective transmitter types 2 to 5 and the system identification words assigned serial number range saved.
- the recipient also contains the algorithm or the mathematical basis which the transmitters 2 to 5 encode the transmission signals.
- the transmitter and receiver of the remote control device can control different functions, for example can when using the remote control device for access to a garage or for another entry control device with a Transmitter and receiver opening and closing the garage door, the lighting and, for example, the activation controlled or deactivation of an alarm system become.
- the functions are on one or programmed several buttons of the respective transmitter, corresponding buttons or switches on the receiver 10 are provided. If multiple functions from the transmitter are controlled, the information on the Function included in the transmission signal and to the Transfer recipient.
- the coding process initialized i.e. the fixed deposit and not Readable system identification word and the serial number of the respective transmitter control the given one Algorithm that functions as a transfer function the corresponding processing unit e.g. 64 Provides a bit long code word. This includes under other also encodes the information about the desired function to be carried out, the synchronization state of the transmitter and the unencrypted serial number of the transmitter.
- the above-mentioned transmitted signal or code word arrives at the receiver 10 by being checked first whether the serial number is from a previous one Initialization or synchronization stored in memory was and is present. If not Case, the transmitted information is ignored and the transmitter treated as unauthorized. Is the serial number all necessary information is stored, namely system identification word, serial number and algorithm before the transmitted transmission signal to decrypt. The system identification word is correct does not match, no decryption be made and the transmitter is again called recognized without authorization. If the identification word is present in the receiver, the signal is decoded and decrypted and the recipient checks whether the serial number of the transmitter in the the system identification word assigned area falls. Is not this the case, the function is not executed. If all values match, the desired one Control made.
- the synchronized System between transmitter and receiver fall out of step, there after another actuation in the reception area i.e. after transmission of the transmitted signal on the recipient decrypting the current Provides synchronization information from the transmitter, which, however, does not differ in the desired way the stored information differs so that the receiver is the one that is connected to it Control device would not control.
- the receiver Tolerance window for the deviations between the in Receiver stored synchronization information and the current synchronization information transmitted by the transmitter intended. Is the synchronization information in the specified predetermined tolerance window, is the desired function anyway executed.
- the first tolerance window can still a second tolerance window is saved in the receiver be larger than the first tolerance window. If the mentioned deviation lies outside the first Tolerance window but within the larger one selected second tolerance window, the current synchronous information cached and the desired one Function not carried out. For the user the impression that the send button is not neat has pressed and this normally pushes them in second time. Now all the information is back transmitted and decrypted and the comparison of the Synchronization information provides the expected Result and the selected function is carried out.
- the small tolerance window includes e.g. Deviations for 16 operations outside the reception area and the larger deviations from very much more activities. Has the button more often pressed than the operations of the second larger The system cannot synchronize the tolerance window and no more functions are performed. In this case a complete resynchronization must be carried out be carried out using voting keys.
- the Radio remote control system comprises a universal transmitter, for example in the case of an entry control device in an automobile, for example in the Sun visor or is arranged in the interior mirror head.
- a universal transmitter for example in the case of an entry control device in an automobile, for example in the Sun visor or is arranged in the interior mirror head.
- the Car manufacturers do this independently of the others Install types of transmitters 2 to 5, i.e. independently of which entry control device the user will use the vehicle later.
- the Universal transmitter is assigned to transmitter type 1.
- This Universal transmitter 1 also has a system identification word SI 1, which is different from the others distinguishes and also in the recipient 10 is stored. So that this transmitter 1 as Universal transmitter can be used is not him Serial number range assigned, but the serial numbers can be assigned without restriction. The The sender can then use all receivers of receiver type 10 speak to.
- the memories contained in the receiver are not volatile, i.e. if the power supply fails the information contained therein is not lost. All possible operating states of the Receivers are shown on a display. The recipient must of course be locked up, So be arranged in the access-protected room unauthorized persons at the press of a voting key to prevent the recipient.
- the transmitter is with a receiving unit and the receiver is provided with a transmitter unit.
- the recipient can, for example, provide feedback indicate whether the desired function has been carried out. This option is particularly useful when activated an alarm system via radio is important because it is recognized whether it is actually initialized has been.
- the Radio transmission for example at one frequency of 433 MHz.
- the Radio transmission for example at one frequency of 433 MHz.
- the Radio transmission for example at one frequency of 433 MHz.
- other transmission paths that perform the function conceivable.
