Definitions

  • This invention relates to an apparatus for transmitting and receiving encoded signals, particularly for remote control.
  • Remote control apparatus comprising one or more transmitters and one or more receivers able to dialogue with said transitters to receive the signals transmitted thereby and transform them into control signals for the desired functions to be performed.
  • the signals emitted by the transmitters are encoded, ie are modified in accordance with a certain code, which can be recognized only by those receivers.
  • the receivers and trasmitters use dip-switches, ie two or three-position multiple switches, ie two or three-position multiple switches, which have to be set to the same configuration in both stations. If n is the number of switches forming the dip-switch, the number of possible different combinations is 2 n or 3 n , the higher the number n the lower the possibility of finding two randomly equal codes.
  • the receiver is set to receive the code and to memorize it in suitable memory locations chosen either randomly or in a predefined manner, the code being generated in the transmitter by a random or non-random procedure and transmitted thereby to the receiver.
  • the transmitter transmits an encoded signal to the receiver, this compares its code with those memorized, and if recognition occurs generates the control signal for the predetermined function to be performed.
  • This solution eliminates the discomfort of having to set the dip-switches in the transmitter and receiver, but does not eliminate the need to gain access to the receiver to set it for memorizing the codes of the transmitters which are to dialogue with it.
  • the apparatus of the invention comprises as its essential elements one or more transmitters indicated overall by 2, and one or more receivers indicated overall by 4.
  • transmitters indicated overall by 2
  • receivers indicated overall by 4.
  • the transmitter 2 comprises a transmitting section 6, for example of radiofrequency, a plurality of funciont keys 8, an enabling key 10 for the receiver 4, a memory 12 in which a number of codes equal to the number of function keys 8 are memorized, and a microcontroller 14 overseeing the operation of the transmitter 2.
  • the codes corresponding to the various keys are memorized by the actual manufacturer, and are indicated by a series number, for the reasons which will be apparent hereinafter.
  • the receiver 4 comprises a receiving section 16 tuned to the frequency of the transmitting section 6 of the transmitter 2, a random access memory 18, a memory cancellation key 20, an acoustic indicator 22 which signals the individual operating stages of the receiver, an overseeing microcontroller 24, and a plurality of outputs 26 for the various functions which the receiver has to control.
  • the apparatus of the invention also comprises a master transmitter 28, comprising a radiofrequency section 30, a keypad 32, a microcontroller 34 operated by said keypad 32, and a display 36 for displaying the operations set by the keypad and processed by the microcontroller 34.
  • This stage requires the memory 18 of the receiver 4 to be empty or to have been completely cancelled by operating the key 20.
  • the user wishing to insert the code of his transmitter 2 into the receiver 4, must firstly operate the key 10 of the transmitter 2 to feed an enabling signal to the receiver 4 which enables it for a short time period (for example a few seconds) to memorize in its memory 18 the code of that transmitter 2. If the user now operates a function key 8 within that time period, the code corresponding to that key is transmitted to the receiver 4, which is able to memorize it in the first empty location of the memory 18, together with correlation data for that function.
  • a short time period for example a few seconds
  • the key 10 of a transmitter 4 must firstly be operated, the code of which has already been inserted into the receiver, so as to set this latter to receive and to memorize the code of the new transmitter in the same manner as indicated for the initial installation.
  • This operation ensures that a new code can only be inserted in the presence of an already enabled transmitter and hence under conditions of absolute security.
  • the cancellation stage can be total, ie involve all the codes inserted into the memory 18 of the receiver 4, or be partial, ie involve only a single code.
  • the operation can be performed in the simultaneous presence of an enabled transmitter 2, which by means of the key 10 causes the receiver to make its memory 18 accessible, and of the master transmitter 28, by which the series number (known) corresponding to that code of the transmitter to be cancelled can be keyed-in via its keypad.
  • the signals transmitted by the transmitter to the receiver can be radiofrequency signals, laser signals or light signals.
  • the apparatus of the invention can be used in various applications.
  • One of these consists of the remote control of tubular motors for operating roll shutters, and motors for operating Venetian blinds.
  • the receiver is integrated into the motor and enables its functions to be totally controlled, including adjustment of limit switches if these are of electronic type. This is also valid if the receiver is external to the motor but, likewise, located in a non-accessible position.
