Abstract

The utility model provides an intelligent eyeshade, comprising a pressure sensing module, an A/D transition module, a main control module, a clock module and a voice prompt module. The intelligent eyeshade is characterized in that the pressure sensing module, the A/D transition module, the main control module and the clock module are connected in sequence, and the main control module is also connected to the voice prompt module. When the rotatory pressure of an eyeball is detected by the pressure sensing module, the detected signal is amplified and filtered by the A/D transition module to be sent to the main control module, the voltage difference of two voltages continuously input is compared to a preset threshold by the main control module, if the voltage difference is greater than the threshold, timing delay is provided by the clock module, and the control voice prompt module prompts a user to get up.

Description

The intelligence eyeshield

Technical field

This utility model relates to a kind of eyeshield, especially intelligent eyeshield.

Background technology

In recent years; There are some researches show that the mankind are waken suddenly in the deep sleep, can cause the trained reflex of bodily protection property, receive this stimulation for a long time; Can cause a series of sleeping problems; Even initiation hypertension, and the alarm clock of set time can't obtain our sleep quality, therefore can't avoid above-mentioned situation.

Summary of the invention

Overcome the above problems in order to improve, this utility model is according to the relation of eyeball rotating speed with the sleep depth, and the sensitive pressure transducer of packing in eyeshield inside can be discerned eyeball more exactly whether at rapid movement, finally controls alarm clock and rings a bell.

This utility model provides a kind of intelligent eyeshield; Comprise pressure sensing module, A/D modular converter, main control module, clock module, voice cue module; It is characterized in that: pressure sensing module, A/D modular converter, main control module, clock module connect successively, and the main control module also is connected with voice cue module.When the pressure sensing module detects oculogyral pressure; Amplify, filter and send into the main control module through the A/D modular converter; The main control module compares with the threshold value that configures through the voltage difference of double input; If greater than threshold value, postpone timing through clock module, control voice cue module prompting user at last and get up.

The beneficial effect of this utility model is, can judge the depth of sleep degree, just can adjust the wake-up time, guarantees the quality of sleep to the full extent, and particularly some middle-aged and elderly people have advantages of high practicability.

The specific embodiment

In Fig. 1; The intelligence eyeshield; Comprise pressure sensing module 1, A/D modular converter 2, main control module 3, clock module 4, voice cue module 5; It is characterized in that: pressure sensing module 1, A/D modular converter 2, main control module 3, clock module 4 connect successively, and main control module 3 also is connected with voice cue module 5.When pressure sensing module 1 detects oculogyral pressure; Amplify, filter and send into main control module 3 through A/D modular converter 2; Main control module 3 compares with the threshold value that configures through the voltage difference of double input; If greater than threshold value, postpone timing through clock module 4, control voice cue module 5 prompting users at last and get up.

What pressure sensing module 1 was used is strain ga(u)ge; Mainly form by sensitive grid, substrate, lead-out wire and cover layer; The sensitivity coefficient of strain gauge depends primarily on the sensitivity coefficient of sensitive grid material, and oculogyral pressure is about 50g, in order fully to reach the sensitivity of foil gauge; Should make the eyeball lateral rotation vertical during installation, touch with grid wire connection as much as possible with the grid direction.The voltage that the voltage acquisition device test amplifier that A/D modular converter 2 adopts main frame and PCF5891 to form is exported; PCF8591 is 8 A/D conversion chip of I2C bus serial read-write; Its maximum characteristics are band auto-increment channel selecting, and standby current is low, and pin seldom is convenient to welding.Main control module 3 is selected the AT89C52 single-chip microcomputer for use, and AT89C52 is 8 single-chip microcomputers of low-voltage, high performance CMOS that American ATMEL is produced, and is powerful, is applicable to many comparatively complicated controls application scenario.What clock module 4 used is the DS1302 chip. it is the trickle charge clock chip that DALLAS company releases, and sheet contains the information in a real-time clock/calendar and static week of 31 bytes, moon, year, and every month the natural law and the natural law in leap year can be adjusted automatically.Voice cue module 5 adopts ISD4000 series monolithic audio record circuits, and each sampled value directly is stored in the flash memory in the sheet, can be very truly, realize voice more naturally, and can let the user in beautiful musical sound, get up.
