Definitions

  • This invention concerns a radio system for the remote control of automated equipment in general, such as closing of accesses, lighting systems, irrigation systems, alarm systems and like.
  • control systems based on portable radio frequency transmitters
  • remote controllers commonly called remote controllers
  • permanent radio receiver devices located in the area where the controlled system is located, are known and already widely used.
  • a signal is sent by a remote control to a radio receiver, which is able to recognise said signal. After correctly interpreting the signal, the radio receiver enables the implementation of the operation envisaged.
  • a unique coded system integrated in the transmission is used even if it may vary in complexity and be fixed or variable (rolling).
  • a remote control is usually set to function with one fixed code or with one variable code. Consequently a radio receiver must be programmed so as to respond only its respective remote control. This obviously means that a manufacturer/ installer of remote controlled, automated equipment must be able to have available and/ or have in store two types of remote control, and relative radio receivers, depending on the coding technique chosen to transmit between one and the other, (fixed or variable code).
  • one of the objects of this invention is to provide an innovative and reliable radio controlled system, comprising at least one dual purpose remote control capable of dialoguing with a radio receiver able to selectively use the coded signals coming from the remote control.
  • a single remote control can be made available for two answer modes on the part of the receiver, to the advantage that a single device compatible with several operating modes and more difficult if not impossible to duplicate can be produced/ or stored in the warehouse.
  • a further object of this invention is to make each individual remote control, univocal and identifiable also within a single system.
  • a remote control system which comprises at least one radio frequency transmitter with one or more control buttons and a radio receiver device, where the radio frequency transmitter is able to simultaneously transmit at least one fixed code and one variable code and the radio receiver is set to receive and recognise selectively the former, the latter or all the coded systems sent by said transmitter so as to activate the automated equipment which is required to be controlled, once the radio receiver has recognised the enabling code or codes.
  • the radio receiver will ignore the other codes present in the transmission.
  • This drawing illustrates a number of radio or remote control transmitters (11) which may be mono- or multi-channel, and a radio receiver device (12) also mono- or multi-channel and designed to interact with said remote controls.
  • Each remote control (11) is usually equipped with one or more buttons to activate transmission towards the radio receiver devices (12), using a radio signal at a given frequency (for example 433,92 MHz).
  • the remote control (11) is preset to transmit a fixed code and a variable code (rolling code), without excluding the possibility of a third fixed code associated with the button.
  • the radio receiver device (12) is preset to receive the coded signals sent by one or more of the remote controls (11) set as stated above. However, the radio receiver device is set to decode, selectively, one or the other of the coded systems transmitted.
  • the remote control always transmits one, two or more codes, and the radio receiver can discriminate the part of the coded transmission that is required to operate the controlled equipment.
