General-purpose remote controller and its setting method

Abstract

The invention discloses a universal remote controller and it's arranging method. The universal remote controller comprises a microprocessor, a keyboard matrix with at least five functions, a sending circuit, a power circuit, an indicating unit, an infrared signal receiving unit and a storing unit, wherein the storing unit stores the processing code and the pre-storing code; the pre-storing code preserves the character data of the 1-5 function key of the provided electric device; the arranging method uses the pre-storing code to look for the first stage arranging of 1-5 function key character data which makes the electric device to generate a response and then look for the second stage arranging of other function key character data which makes the electric device to generate a response.

Description

technical field [0001] The invention relates to a universal remote control and its setting method, belonging to electronic remote control technology. Background technique [0002] In the prior art, in order to realize the centralized remote control of various electrical appliances, a so-called universal remote controller that can remotely control multiple electrical appliances is used. This kind of universal remote control is to pre-store the code groups of various devices such as TV, VCR, CABLE, SATELLITE, CD, LD, DVD, VCD, TAPE, TURNER, STB, IPTV (excluding air conditioners) into the remote control micro In the processor or memory unit chip. In order to enable the remote control to control more devices, it is generally possible to load as many remote control codes of different brands and types in the microprocessor or storage unit as possible. And each group of remote control codes A specific brand, model, and type of electrical appliances can be remotely controlled, and ...

Problems solved by technology

[0012] To sum up, the existing universal remote controllers including Chinese Patent Publication No. CN1591287A all have long time for setting or searching for codes and cumbersome setting methods; the coded data of all keys of the remote controller cannot be set at one time; The coding data of all the keys of the original remote control cannot be set and copied to any key position of the remote control; the coding data of the remote control keys is incomplete or the combination is not satisfactory, and even the searched and stored electrical remote control codes are incomplete and cannot be used; Replace the infrared remote controller of any electrical equipment in any period; and due to the need to store all the key code data of the remote controller, the requirements for the read-only memory (ROM) of the single-chip microcomputer (MCU) to it are relatively high, so its development and preparation costs are also high. Higher deficiency

Especially Chinese Patent Publication No. CN1591287A adopts LCD display unit, and its preparation cost will be higher

[0013] Today, the number of electrical equipment controlled by remote controls in modern families is increasing day by day. People are more and more aware of the dedicated remote control for a single electrical equipment; it brings many troubles in use and storage, and when the remote control is used After the loss, you have to go to a specialty store to buy the same remote control, which is really inconvenient and adds to the financial burden
