The defective of prior art is: the set-top box of air-conditioning, televisor etc. is subjected to the electrical equipment of infrared remote control, can only realize control to electrical equipment having limited service time by the manual operation telepilot, makes troubles to use.

The utility model content

The purpose of this utility model provides a kind of intelligent infrared ray remote control device, can the corresponding electrical equipment of timing automatic control, enlarged service time, and offer convenience for people's life.

For achieving the above object, the utility model is explained a kind of intelligent infrared ray remote control device, include main control circuit and LCD chip, the data transmission terminal of described main control circuit is connected with the data transmission terminal of LCD chip, its key is: also include clock chip and button groups is set, described clock chip is connected with crystal oscillator, the data I/O end of this clock chip, the serial clock signal end, reset terminal connects the data I/O end of main control circuit respectively, clock signal terminal, reseting controling end, the end that described each that is provided with in the button groups is provided with button connects the signal input end of main control circuit, other end ground connection respectively.

The number that button is set in the button groups is set can be set up on their own by the user as required, all are provided with button and are used in combination, be used for being provided with time and mode of operation, this time and mode of operation are kept in the clock chip by main control circuit, when the main control circuit judgement reaches setting-up time, main control circuit starts the control sequence of setting the mode of operation correspondence automatically, gives an order to electrical equipment, makes electrical work under the mode of operation of setting.The LCD chip is used for showing, is convenient to user's setting and understands current time and mode of operation.

The utility model also includes reset circuit, and this reset circuit is made up of pull down resistor and electrochemical capacitor, and the positive pole of described electrochemical capacitor is connected with positive source, and negative pole is through pull down resistor ground connection, and this negative pole also connects the reset terminal of main control circuit.

Reset circuit is used to realize resetting to main control circuit.

In order to keep the manual control function of original telepilot, the utility model also includes one 8 * 4 button matrix, an end of 4 buttons at each row place interconnects in this matrix, 8 row buttons are connected with 8 capable signal input parts of described main control circuit respectively, the other end of 8 buttons at each row place interconnects in the matrix, and 4 row buttons are connected with 4 column signal input ends of described main control circuit respectively.

Remarkable result of the present utility model is: can the corresponding electrical equipment of timing automatic control, also have original manual control function simultaneously, as long as set time and mode of operation in advance, just can be in the control of setting-up time realization to electrical equipment, enlarged service time, offered convenience for people's life.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment:

As Fig. 1,2,3,4, shown in 5: a kind of intelligent infrared ray remote control device, include

main control circuit

1,0802A type LCD chip 2, DS1302 type clock chip 3 and button groups 4 is set, described main control circuit 1 adopts the W78LE51 chip, the data transmission terminal P0 mouth of this main control circuit 1 is connected with the data transmission terminal DB0～DB7 of LCD chip 2, described clock chip 3 is connected with crystal oscillator, the data I/O end I/O of this clock chip 3, serial clock signal end SCLK, reset terminal RST connects the data I/O end P2.3 of main control circuit 1 respectively, clock signal terminal P2.2, reseting controling end P2.4, the described button groups 4 that is provided with is provided with button S1 by four, S2, S3, S4 forms, each is provided with button S1, S2, S3, the end of S4 connects the signal input end P3.2 of main control circuit 1 respectively, P3.1, P3.0, P3.3, other end ground connection.
