Definitions

  • the invention relates to a transmitter for a remote control group for a shared function such as opening a garage door. It also relates to a receiver for such a group and to a group of a receiver and a plurality of transmitters.
  • a remote control group transmitter comprising a transmitting device, a user transmit button, a processor, and a memory, characterised in that,
  • the valid code is variable according to pre-set criteria.
  • the valid code comprises a hopping index.
  • the valid code comprises a combination of a fixed discrimination value known to the receiver and a hopping index.
  • the transmitter comprises means for learning the encryption key in response to a teaching radiation signal.
  • the transmitter comprises means for generating the encryption key by processing a manufacturer-set key with a site code which is unique to the group.
  • the transmitter comprises means for receiving the site code in an encrypted teaching radiation signal and for decrypting said signal to determine the site code using a teaching decryption key.
  • the transmitter comprises means for storing a transmitter-specific serial number and for transmitting the serial number together with the encrypted code.
  • the invention provides a remote control group master transmitter for teaching a transmitter as described above, the master transmitter comprising a memory, a processor, and a transmit device, wherein the processor comprises:
  • the invention provides a receiver for a remote control group having a transmitter as described above, the receiver comprising a memory, an interface to a shared function, and a processor comprising means for controlling the shared function via said interface, wherein the processor further comprises:-
  • the processor comprises means for:
  • the processor comprises means for determining if the serial number is valid by:
  • FIG. 1 is a schematic diagram of a remote control group transmitter of the invention.
  • remote control group transmitter 1 comprises:
  • the memory capacity is adequate for four sets of data, as described above. This allows the transmitter 1 to be used for up to four different remote control groups. However, for clarity, operation for only one group is described below.
  • the microprocessor 2 is programmed to recognise a switch 7 depression as a transmit instruction. Simultaneous depression of two or more switches in various pre-set configurations are interpreted as user instructions for auxiliary functions such as a teach mode or randomisation of codes. Programming of the microprocessor 2 at manufacture determines whether the transmitter is a master or a slave. Slaves do not have a teach mode. The transmitter 1 is a slave.
  • the transmitter 1 is part of a remote control group also comprising a receiver and a master transmitter.
  • the latter is used for teaching both the receiver and the transmitters 1. It has the same hardware configuration as the transmitter 1, but is additionally programmed with a teach mode.
  • the remote control group is given a unique site code by the installer and the master transmitter teaches the site code to the receiver and to the transmitters 1. This effectively empowers the installer to set the manner in which the remote control group operates from a security viewpoint.
  • Each master transmitter is pre-programmed at manufacture with a unique (to it) site code. Therefore the installer may use the pre-programmed site code of a master transmitter as that of the group. Alternatively, he may change it by randomising the pre-set value.
  • Each new transmitter stores the following after manufacture:
  • the master transmitter teaches the site code to a (slave) transmitter 1 using a teaching encryption key.
  • the transmitter 1 decrypts it using a teaching decryption key.
  • the transmitter 1 uses the site code to generate the encryption key for use in sending signals to the receiver for control of the shared group function. After it is used to generate the encryption key, it is not necessarily stored as it is not required again.
  • the encryption key is 64 bits long.
  • the master transmitter also teaches a discrimination value to the transmitter 1. This is an agreed value that enables the receiver to determine that it has correctly decrypted the transmission. It could, for example, be part of the site code or the serial number or any other agreed number.
  • the encryption key could alternatively be generated by only the master transmitter and taught to the receiver and the transmitters 1. However this suffers form the disadvantage of involving transmission of the encryption key.
  • the microcontroller encrypts the initial hopping index and the discrimination value with the encryption key to provide a valid encrypted code.
  • the (unencrypted) serial number and the encrypted code are transmitted, and are received by the receiver.
  • the receiver decrypts the code using its stored decryption key to determine the discrimination value and the initial hopping index.
  • the receiver checks the (decrypted) discrimination value and, if valid, it stores the serial number and the initial hopping index.
