Abstract

The utility model discloses an infrared-induced doorbell, which comprises a receiver and a transmitter, wherein the receiver comprises an RF (Radio Frequency) receiving circuit, a receiving-control module which is connected with a receiver power supply and a power amplifier, the transmitter comprises a transmitter power supply, a main controller and an RF transmitter, the RF receiving circuit is connected with the power amplifier through the receiving-control module, the control over the receiving-control module is realized by the receiver through the RF receiving circuit, the receiving-control module comprises a decoder which is connected with the main controller, an address memory and a playing sound-source module, the decoder is connected with the address memory, an encoder in the transmitter is connected with an RF transmitting circuit through the main controller, the control over the RF transmitting circuit is realized through the main controller, and both the main controller and the RF transmitting circuit are connected with the transmitter power supply. The infrared-induced doorbell has the beneficial effects that: a human body is induced through an infrared-induced head, the infrared-induced doorbell is convenient and practical, the inducing distance is long, the capacity of a memory in the receiver is large, and the signal-receiving distance is long.

Description

A kind of infrared induction doorbell

Technical field

The utility model relates to a kind of doorbell of Remote, particularly a kind of infrared induction doorbell.

Background technology

Existing doorbell generally comprises and places outdoor emitter and place indoor receiving trap, and receiving trap is provided with loudspeaker, and when the button on the emitter was pressed, loudspeaker sent the tinkle of bells and notifies indoor owner.But the range of control of existing remote control doorbell is less, and the music of doorbell is more single uninteresting, and existing doorbell all need be through pressing bell button, and doorbell is just sounded, if but sometimes two hands carrying thing, just very inconvenient when need press doorbell.

The utility model content

To the defective of existing remote control doorbell, the utility model provides a kind of infrared induction doorbell.

To achieve these goals, the measure taked of the utility model is:

A kind of infrared induction doorbell; Comprise transmitter and receiver, transmitter is made up of transmitter power, master control and RF transmitter, and receiver is made up of RF receiving circuit, the reception control module and the power amplifier that are connected with receiver power supply; Master control all links to each other with transmitter power with the RF radiating circuit; Be connected with scrambler and infrared induction head in the master control that the RF radiating circuit links to each other, be provided with infrared processor between master control and the infrared induction head, realize control through master control to the RF radiating circuit; The RF receiving circuit links to each other with power amplifier through receiving control module; Receiver achieves a butt joint through the RF receiving circuit and receives the control of control module, receives control module and comprises demoder, addressed memory and the broadcast source of sound module that links to each other with primary controller, and demoder links to each other with addressed memory;

The voltage of said receiver power supply is 4.5V;

Said transmitter power is the battery of 9V voltage.

The beneficial effect of the utility model: transmitter need not pressed bell button through infrared induction head induction human body, and convenient and practical, the human body sensing distance of infrared induction head reaches 5 to 8 meters; The capacity of the storer in the receiver is big, can store how first doorbell music, and the reception signal distance of receiver is far away, reaches more than 100 meters.

Embodiment

A kind of infrared induction doorbell; Comprise transmitter and receiver, transmitter is made up of transmitter power, master control and RF transmitter, and receiver is made up of RF receiving circuit, the reception control module and the power amplifier that are connected with receiver power supply; Master control all links to each other with transmitter power with the RF radiating circuit; Be connected with scrambler and infrared induction head in the master control that the RF radiating circuit links to each other, be provided with infrared processor between master control and the infrared induction head, realize control through master control to the RF radiating circuit; The RF receiving circuit links to each other with power amplifier through receiving control module; Receiver achieves a butt joint through the RF receiving circuit and receives the control of control module, receives control module and comprises demoder, addressed memory and the broadcast source of sound module that links to each other with primary controller, and demoder links to each other with addressed memory; The voltage of said receiver power supply is 4.5V; Said transmitter power is the battery of 9V voltage.

In the use; When people the place ahead at the infrared induction head of doorbell emitter; The signal that the infrared induction head is sensed is passed to master control through infrared processor, and master control control RF radiating circuit is launched signal, and receiver receives the signal that transmitter sends; Receive control module by RF receiving circuit control, whether send the size, type of the tinkle of bells and the tinkle of bells etc. through the loudspeaker on the primary controller controlling receiver.

Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in this area.
