There is described a remote controller using electromagnetic waves with automatic learning functions, characterised in that it comprises in combination: a radio-frequency unit (16) provided with at least one receiving device and one transmitting device and connected to at least one receiving and transmitting aerial (18); a microprocessor unit (10) connected to the said radio-frequency unit (16) so that it can receive data from it and send to it command signals and data to be transmitted; a memory (14) for the storage of the data; and a keypad (12) by means of which the user sends the operating commands to the microprocessor (10), the arrangement being such that, when a learning key is pressed for the emulation of an original remote controller, the microprocessor (10) prepares the receiving device of the radio-frequency unit (16) for operation, analyses the data received from it, varies its operating parameters until it identifies the operating parameters of the original remote controller, and stores in the memory (14) the operating parameters thus identified, while, when a key is pressed to remotely control the controlled equipment, the microprocessor (10) retrieves from the memory (14) the previously stored operating parameters and, by means of these, prepares for operation and activates the transmitting device of the radio-frequency unit (16). |
