Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment is implemented under take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment:
Referring to Fig. 1, doorway machine comprises a surface-mounted integrated circuit, power module, LED display circuit, is equiped with the infrared proximity sensor circuit on the surface-mounted integrated circuit, and this infrared proximity sensor circuit is divided into infrared transmitting terminal and infrared receiving end.Infrared transmitting terminal comprises transmission single-chip microcomputer, infrared transmitting tube, and sending single-chip microcomputer is a series of burst signal with binary signal coded modulation to be sent, by infrared transmitting tube emission infrared signal.The modulation of binary signal is still finished by sending single-chip microcomputer, and it is modulated into the discontinuous pulses string that frequency is 38KHz to the binary signal after working out, and namely is to be used for the signal that infrared-emitting diode sends after the modulation.
Infrared receiving end comprises infrared receiving terminal, receives single-chip microcomputer, and when the user was arranged near doorway machine, because people self can launch infrared ray, and the people can also reflect by infrared transmitting tube emission infrared signal, and these infrared signals are received by infrared receiving terminal.Infrared receiving terminal amplifies the infrared signal that receives, after detection, Shape correction obtain the coded signal of Transistor-Transistor Logic level, send the reception single-chip microcomputer to again, through receiving the decoding of single-chip microcomputer decoding circuit and carrying out, removes to control the LED display circuit.
The modulation of binary signal is finished by integrated infrared receiving terminal, and it restores the infrared signal of receiving through inter-process and modulation, output.The demodulation of infrared receiving terminal can be regarded as: when input has train of impulses, and output terminal output low level, otherwise output high level.Binary decoding is finished by receiving single-chip microcomputer, and the binary coding ripple that it sends infrared receiving terminal here passes through decoding, restores the data that transmitting terminal sends.Begin as transmission by the high level of 20 pulse widths of single-chip microcomputer transmission first in the beginning that sends byte, then send 8 bit data, a byte high position is front, and low level is rear.Send at last the low level of 10 pulse widths as end of transmission (EOT).
Referring to Fig. 2 and Fig. 3, the dotted line frame represents the LED display circuit among Fig. 2, the base stage of the triode amplifier biasing resistor R33 that connects in the LED display circuit, this biasing resistor R33 connect with receiving the single-chip microcomputer decoding circuit, receives the resistance R 31 of connecting on the single-chip microcomputer decoding circuit.The collector of triode amplifier links to each other with the negative pole of diode, the positive pole of the diode current-limiting resistance R34 that connects.
When the user is arranged near doorway machine, infrared proximity sensor circuit of the present invention, by the infrared induction principle, people's self infrared ray and the infrared signal of reflection are received by infrared receiving terminal.Infrared receiving terminal sends the reception single-chip microcomputer to after the infrared signal that receives is processed, through receiving the decoding of single-chip microcomputer decoding circuit and carrying out, the base current of triode amplifier is very large in the LED display circuit at this moment, triode amplifier is in state of saturation, circuit debugging, diode current flow, LED display brightens, and the user can operate according to the prompting on the doorway machine display screen easily.
When the user leave or nobody when the doorway machine, the receiving end of infrared proximity sensor circuit of the present invention does not have signal, the base current of triode amplifier is 0 in the LED display circuit of reception single-chip microcomputer decoding circuit control, the collector current of triode amplifier also is 0, this moment, triode amplifier was in cut-off state, and circuit disconnects, and diode disconnects, LED display is closed, thereby has reached energy savings and prolonged the LED display purpose in serviceable life.
Fig. 3 is doorway machine internal circuit schematic diagram of the present invention, sends single-chip microcomputer and adopts ATmega88, and there is the program storage of 2KB inside, and there are 8 parallel ports the outside, and selecting crystal oscillator frequency is 24MHz.
The present invention is connected on the doorway machine among Fig. 3, open, end by the infrared induction principle in the infrared proximity sensor circuit and triode amplifier saturated and disconnect the automatic shutter that principle just can realize LED display in the doorway machine, energy savings, prolonging LED display is the life-span.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
