Abstract

The utility model discloses a kind of a kind of human body sensing device of low-power consumption of electronic product, mainly include PCB substrate, infrared transmitting tube and infrared receiving tube, wherein infrared transmitting tube and infrared receiving tube are arranged on the homonymy of PCB substrate, and the infrared ray of infrared transmitting tube transmitting is consistent with the specific frequency of infrared receiving terminal in infrared receiving tube;When human body is close to induction installation, the infrared ray of infrared transmitting tube transmitting is reflected by human body, and infrared receiving terminal receives the infrared ray reflected by human body, responds.The beneficial effects of the utility model are:Infrared transmitting tube and infrared receiving tube are set using homonymy, and transmitting is identical with the frequency for receiving head, no human body close to when, product can dormancy always be in extremely low power dissipation state, the great power consumption of reduction entirety;When human body is close to induction installation, infrared receiving terminal receives just to be responded by the infrared ray of human body reflection.

Description

A kind of human body sensing device of low-power consumption of electronic product
Technical field
It the utility model is related to, a kind of human body sensing device of low-power consumption of mainly a kind of electronic product.
Background technology
At present, because existing some electronic products such as electronic lock, Fingerprint Lock etc use battery powered, the power consumption of product into For a critically important index.Even some products are often changed battery and returned goods by customer because power consumption is too big.It is logical Often, as product of the electronic lock etc using battery as power supply all reduces power consumption using the method for dormancy, main control chip is usually In a dormant state, meanwhile, the device that can be closed is closed or is similarly in dormancy, it is main when there is particular event generation Chip is controlled to wake up, meanwhile, corresponding device is waken up into normal work.
Utility model content
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of a kind of low of electronic product The human body sensing device of power consumption.
The purpose of this utility model is completed by following technical solution.A kind of low-power consumption of this electronic product Human body sensing device, mainly including PCB substrate, infrared transmitting tube and infrared receiving tube, wherein infrared transmitting tube and infrared receiver Pipe is arranged on the homonymy of PCB substrate, the specific frequency of infrared receiving terminal in the infrared ray and infrared receiving tube of infrared transmitting tube transmitting Rate is consistent;When human body is close to induction installation, the infrared ray of infrared transmitting tube transmitting is reflected by human body, and infrared receiving terminal receives The infrared ray reflected by human body, is responded.
Further, the infrared ray consistent with infrared receiving terminal response frequency is launched in described infrared transmitting tube timing, Infrared receiving terminal responds to the infrared ray of specific frequency within a certain period of time, controls main control chip and according to pre-set programs work Make.
Further in the frequency of modulation on the infrared ray of transmitting and infrared receiving terminal response.
The beneficial effects of the utility model are:Infrared transmitting tube and infrared receiving tube are set using homonymy, transmitting and reception Head frequency it is identical, no human body close to when, product can dormancy always be in extremely low power dissipation state, greatly reduce integrally Power consumption;When human body is close to induction installation, the infrared ray of infrared transmitting tube transmitting is reflected by human body, and infrared receiving terminal receives The infrared ray reflected by human body, is responded.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing:
As illustrated, a kind of human body sensing device of low-power consumption of this electronic product, mainly include PCB substrate 1, infrared Transmitting tube 2 and infrared receiving tube 3, wherein infrared transmitting tube 2 and infrared receiving tube 3 are arranged on the homonymy of PCB substrate 1;Launching Infrared ray on modulation with infrared receiving terminal response frequency, infrared transmitting tube 2 launch infrared ray with it is red in infrared receiving tube 3 The specific frequency of outer reception head is consistent;Described infrared transmitting tube 2 is regularly launched consistent with infrared receiving terminal response frequency red Outside line, no human body close to when, product can dormancy always be in extremely low power dissipation state, greatly reduce overall power consumption. When human body is close to induction installation, the infrared ray that infrared transmitting tube 2 is launched is reflected by human body, and infrared receiving terminal is received by human body The infrared ray of reflection, infrared receiving terminal respond to the infrared ray of specific frequency within a certain period of time, and control main control chip is simultaneously Worked according to pre-set programs.
The integrated infrared receiving terminal of infrared receiving tube, internal circuit include infrared monitoring diode, bandpass filter etc.. Because having bandpass filter in infrared receiving terminal, thus the infrared signal that a certain specific frequency can only be sensed it is common household electrical appliance it is distant Control receiver is much this infrared receiving terminal, so avoids the interference of infrared signal in nature.Hot outgoing Penetrate pipe transmitting infrared ray with reception head specific frequency it is consistent when, the infrared signal of transmitting can just be sensed by reception head.
Operation principle:Infrared receiving terminal can make a response within the extremely short time to the infrared ray of specific frequency, we Purpose with regard to reaching low-power consumption using the principle.
By taking conventional 38K infrared receiving terminal as an example, the reception head response time of many models is 6-10 pulse for we, That is, after infrared receiving terminal receives infrared ray 158uS to the 270uS times reflected, receive head can and make Response, control main control chip work.
We are in design, using timing working mechanism.Infrared transmitting tube timing transmitting is consistent with receiving head response frequency Infrared ray the frequency for receiving head response is modulated on the infrared ray of transmitting, the time launched every time is very short.When infrared ray is anti- When penetrating, receive head and respond and worked according to pre-set programs.
If we set infrared tube transmitting in each second, received once, each duration 300uS, transmitting and reception Circuit total working electric current 10mA is calculated, and equivalent average current is:10mA X 0.3mS/1000mS=3uA.That is, I Can complete human body induction function with 3uA current drain, can also be at this if the human body sensing distance that we require is near Current drain is reduced on the basis of individual.
It is understood that it will be understood by those skilled in the art that to the technical solution of the utility model and utility model structure Think to be subject to equivalent substitution or change all belong to scope of the claims appended by the utility model.
