Description

The intelligent household appliance remote controller

The utility model relates to a kind of intelligent household appliance remote controller of using more.It is a kind of remote controller that is used to control air conditioner, removes this, also can be used for controlling multiple other household electrical appliance.

Existing domestic electrical equipment remote controller, for example the remote controller of usefulness such as television set, video tape recorder, sound equipment, laser enlarger, air conditioner, electric fan generally all is infrared emission-reception control, and corresponding one by one the use.In the recent period some remote controllers that occur have a machine and control function more, and form has multiple, and a kind of is the television set that integrates multiple import plate, video tape recorder distant control function; Another kind is respectively multiple import, homemade television set to be carried out remote control, compatible video disc player, VCD machine, CD player part, can carry out remote control to multiple import, homemade video disc player, VCD machine, CD player respectively, but remotely-controlled object compiles and edits relatively, has limited the use flexibility.

Also having more advanced is to adopt the monolithic processor controlled remote controller of Z80.It is provided with the standard infrared code of producer's product both at home and abroad such as many companies such as Sony, Panasonic, triumph, Sharp in advance, only need the receiving infrared-ray module of this remote controller relative during use with the output emission LED of the infrared remote controller of another product, then can receive the other side's infrared code, and remember, addressing, when re-using, can accomplish that then a remote controller controls a plurality of electric products.But this series products lacks " self study " function and use Z80 single-chip microcomputer circuit still to dislike complicated.Looking into new Patent data through science and technology has: 1, infrared ray multi-purpose remote controller, CN2250552Y; 2, intelligent infrared remote controller, CN2211633Y; 3, the method and apparatus of remote control, CN1119474A.See from the content of data report and still to find no and intellectuality that the utility model has " self study " function.

The purpose of this utility model provides a kind of band MC6805L5 type single-chip microcomputer and EPROM data storage circuitry newly developed, the intelligent household appliance remote controller with intellectuality " self study " function.

The utility model is by oscillation source, single-chip microcomputer, keyboard circuit, remote control infrared emission circuit, infrared receiving test circuit, E ²Compositions such as PROM data storage circuitry, liquid crystal display and drive circuit.

The basic functional principle of remote controller: the work of remote controller is controlled by keyboard operation.During certain operation keys on pressing remote controller, the corresponding keyboard input port by its inner single-chip microcomputer receives the information that a corresponding key is pressed incident, and single-chip microcomputer will be judged this information and compare immediately, and makes corresponding associative operation.At first, this key is made differentiation, find out key corresponding codes information or associative operation therewith, handle through single-chip microcomputer, work out out a corresponding control coding, be emitted on the controlled plant (household electrical appliances) by radiating circuit then, make controlled plant make corresponding operation, thereby reach the purpose of remote control according to respective coding.

The control of remote controller coding is followed same coding agreement with controlled home appliance, often is made up of a series of pulse width modulated waves or frequency modulation type pulse.Because household appliances are diversified, and manufacturer has nothing in common with each other, thereby also just makes the control of remote controller coding possess multiple concrete way of realization is arranged.In order to realize the intelligent multifunctionization of remote controller, the utility model has adopted E ²PROM data-storing technology by the control of " pattern " key on the keyboard with " study " key, and cooperates corresponding software, can realize the detection differentiation to the corresponding encoded of learned remote control, and control E simultaneously ²The read-write operation of PROM is realized the storage of the corresponding coded message of this key study or is called corresponding memory cell internal information, the infrared signal of launching corresponding certain key.Thereby reach the function of learning and memory or emission.

The utility model has had a kind of modal remote controller coded message at air conditioner and colour TV, makes this remote control not add the user under the situation of any other operation bidirectional, can possess the distant control function that has a kind of air conditioner and colour TV.For controlling more kinds of home appliances, we adopt " study " function of this remote controller, the E that goes back before adopting ²The intelligent memory storage method of PROM makes that the user can be to " study " of certain remote controller key outupt coded signal of being learnt, thereby makes and only need adopt this remote controller just can control multiple home appliance.That is to say that the user controls air conditioner, the colour TV except using this remote controller, only need operation a little, promptly can pass through E ²PROM data-storing technology and corresponding software are differentiated and are analyzed, and make this remote controller can also pass through the mode of " study " easily, have both the multipurpose function of other household electrical appliance such as control colour TV, VCD machine, sound equipment, fan are arranged simultaneously.For example, want to control another kind of home appliance as the user with this remote controller (being called remote controller A), such as colour TV, the colour TV corresponding remote controller is called remote controller B therewith, in order to reach with this remote controller A, the main distant control function that has both remote controller B can be done following operation and be realized.1, remote controller A is gone up " MODE " key and switch to corresponding " TV " operating state.2, push " LEARN " key on the remote controller A, it is switched to " study " state.3, press some keys on the remote controller A, this key desires to be used for the corresponding keys of certain the key function on the replacement remote B for the user.4, remote controller B is aimed at the reception head of remote controller A, push the replaced key of desire,, represent that promptly this key is remembered successfully when remote controller A shows " success " information.According to this, later on as long as this remote control of operation A can replacement remote B.

Advantage of the present utility model:

1, adopts the strong MCHC05L5 single-chip microcomputer of function, line construction compactness, simplification.

2, adopt singlechip technology and E ²The PROM data storage technology makes remote controller have intelligent self-learning function.Realize this remote controller and also have multipurpose remote control function except that making the air conditioner remote controller, a machine is controlled more.

3, adopt E ²The PROM data storage technology, having data can read and write at any time, the non-volatile characteristics of power down, reliable operation.

4, the control panel supervisory keyboard divides three row to arrange, and is clear, easy to operate.

5, adopt liquid crystal display to make remote controller image reflection operating state, handled easily.
