Abstract

A kind of glasses correct placement alarm set of the utility model, including for detecting whether glasses are worn on pyroelectric sensor on the face, for detect glasses whether the contact sensor of correct placement, the pyroelectricity signal transmitted for receiving pyroelectric sensor, and start contact sensor when pyroelectricity signal is not worn on the face for glasses, the controller of a switching signal to switch is issued when the signal that contact sensor transmits is activation signal, button cell, switch, warning lamp and/or buzzer, pyroelectric sensor is placed on the inside of the knee of the temple of glasses, contact sensor is placed on the outside of the middle position of the connection frame between two lens frames of glasses, controller, button cell and switch are placed in temple, warning lamp and/or buzzer are placed in temple, button cell, switch and warning lamp and/or buzzer constitute one Circuit loop, pyroelectric sensor, contact sensor, button cell and switch are electrically connected with the controller.

Description

Glasses correct placement alarm set

Technical field

The utility model relates to optometric technology fields, more particularly to a kind of glasses correct placement alarm set.

Background technique

It is existing that often at random glasses are placed on desk when people take glasses, without correct placement eye Mirror, and the mirror surface front of glasses is placed on desk, be will lead to mirror holder over time and is easily deformed, and mirror surface can grind flower, thus The function of influencing glasses is unfavorable for protecting eye eyesight.

Utility model content

The utility model is in view of the problems of the existing technology and insufficient, provides a kind of glasses correct placement alarm set.

The utility model is to solve above-mentioned technical problem by following technical proposals:

The utility model provides a kind of glasses correct placement alarm set, it is characterized in that comprising for detecting glasses Whether be worn on pyroelectric sensor on the face, for detect glasses whether correct placement contact sensor, for receiving heat Release the pyroelectricity signal that electric transducer transmits and pyroelectricity signal be glasses be not worn on the face when starting contact sensor, The signal that contact sensor transmits be activation signal when issue a switching signal to switch controller, button cell, switch, Warning lamp and/or buzzer, the pyroelectric sensor are placed on the inside of the knee of the temple of glasses, and the contact sensor is set On the outside of the middle position of connection frame between two lens frames of glasses, the controller, button cell and switch are placed in mirror In leg, the warning lamp and/or buzzer are placed in temple, the button cell, switch and warning lamp and/or buzzer structure At a circuit loop, the pyroelectric sensor, contact sensor, button cell and switch are electrically connected with the controller.

Preferably, the controller selects PLC.

Preferably, the warning lamp is LED light.

On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with Good example.

The positive effect of the utility model is:

The utility model can remind in time people's glasses not put correctly when people do not have correct placement glasses It sets, please in time by glasses correct placement, to prevent the mirror surface of glasses from being spent by mill.

Detailed description of the invention

Fig. 1 is the structural block diagram of the glasses correct placement alarm set of the utility model preferred embodiment.

Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to In the range of the utility model protection.

As shown in Figure 1, the present embodiment provides a kind of glasses correct placement alarm sets comprising for whether detecting glasses Be worn on pyroelectric sensor 1 on the face, for detect glasses whether correct placement contact sensor 2, release for receiving heat The pyroelectricity signal and the starting contact sensor, In when pyroelectricity signal is not worn on the face for glasses that electric transducer transmits The signal that contact sensor transmits be activation signal when issue a switching signal to switch PLC 3, button cell 4, switch 5, LED light 6 and buzzer 7, the pyroelectric sensor 1 are placed on the inside of the knee of the temple of glasses, and the contact sensor 2 is set On the outside of the middle position of connection frame between two lens frames of glasses, the PLC 3, button cell 4 and switch 5 are placed in mirror In leg, the LED light 6 and buzzer 7 are placed in temple, and the button cell 4, switch 5 and LED light 6 and buzzer 7 are constituted One circuit loop, the pyroelectric sensor 1, contact sensor 2, button cell 4 and switch 5 are electrically connected with PLC 3.

Pyroelectric sensor 1 is placed on the inside of the knee of the end of temple, and when putting on one's glasses, pyroelectric sensor 1 is general Close to skin, so can accurately detect that glasses are worn this case.

Pyroelectric sensor 1 detects whether glasses are worn on the face, and the pyroelectricity signal that will test is transmitted to PLC 3, PLC 3 are judging that pyroelectricity signal is that starting contact sensor 2 works when glasses are not worn on the face, contact sensor 2 Detect whether contact object (such as desk), and the activation signal that will test is transmitted to PLC 3, PLC 3 is in activation signal Switching signal is sent when contacting the signal of object to switch 5, the circuit loop where switch 5 is connected, and LED light 6 is lighted flashing and mentioned Awake user's correct placement glasses, 7 sounding reminding user's correct placement glasses of buzzer.

Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence Change, but these change and modification each fall within the protection scope of the utility model.
