Abstract
The utility model relates to a remote device capable of locking, which is the improvement of the structure of the remote controller of the air conditioner. The utility model mainly comprises a housing, a liquid crystal, a conductive button, a battery, a circuit board and other parts. The housing is additionally provided with a locking key and is connected in a keyboard circuit. The utility model has the advantage that other keys can be locked in the operation process, so unexpected change can not appear by pressing other keys by accident. When the locking key is pressed again, the locking function can be eliminated.
Description
The utility model relates to a kind of improvement of remote controller structure of air-conditioner, is a kind of lockable remote controller specifically.
The employed remote controller of existing air-conditioner, its controller there is not locking mechanism, no matter if therefore run into any one button on remote controller surface unintentionally, all can make the display change on the remote controller LCD Panel, having occurred is not the subjective desirable changes of people.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of lockable remote controller, increases locking key in its operating circuit, after pressing locking key, with lockable locking remote controller, have only to click locking key again, function just can unlock.
The utility model purpose is realized by following technical scheme: the lockable remote controller of this kind, its structure mainly include housing, liquid crystal, conducting resinl key, battery and wiring board, set up locking key on housing, and are connected in the keyboard circuit.
The course of work of locking key is as follows: when pressing locking key, by the scanning of keyboard, this signal is read into CPU, and when computer identifies when being locking key, program is promptly blocked the processing (except the ON/OFF key) to other keys.When pressing locking key again, this signal is transfused to CPU again, and it is the signal of locking key input that computer identifies, and CPU promptly removes the blockade to other keys.Pressing locking key each time, is to block other keys, still removes the blockade to other keys, realizes by setting high and low level.Its circuit working principle is as follows: when not pressing locking key T, locking key pin Po end is high level, and this signal is transfused to CPU, and the function of each pin is not locked, when pressing locking key, operating circuit is connected, and locking key pin Po end is low level, and this signal is read into CPU, CPU blocks other pin functions, (except the pin of ON/OFF key) promptly blocks the processing to other buttons, locked other buttons.Otherwise, also set up.Promptly can set locking key pin Po and hold when being high level, locking when being low level, unlocks.
The utility model has the advantages that owing on remote controller, set locking key, and be connected in the keyboard circuit that increased lock function, when using a teleswitch, can not occur because having pressed other buttons unintentionally is not the subjective desirable changes of people.Only after pressing locking key again, function just can unlock.
Embodiment of accompanying drawings:
Fig. 1, Fig. 2 are lockable remote controller structural representations,
Fig. 3 is the locking key fundamental diagram,
Fig. 4 is a kind of application circuit.
This lockable remote controller mainly comprises, housing (1), liquid crystal (2), conducting resinl key (3), battery (4), circuit board (in housing) five most compositions.Housing is provided with locking key T, and Po is a locking key pin pipe, and when not pressing locking key T, locking key T pin Po end is high level, this signal input CPU, and the function of each pin is not locked; When locking key T was pressed, circuit was connected, and locking key pin Po is low level, and this signal is read into CPU, and CPU blocks other pin functions, has promptly locked other buttons.
Claims (2)
1, a kind of lockable remote controller, its structure mainly includes: housing, liquid crystal, conducting resinl key, battery, wiring board is characterized in that increase is provided with locking key on housing, and are connected in the keyboard circuit.
2,, it is characterized in that the two ends of locking key are connected with two pins of chip respectively by connecting line according to the described lockable remote controller of claim 1.
