Description
Technical field
The utility model relates to a kind of related preventive technology, especially relates to a kind of sitting posture reminder.
Background technology
Along with socioeconomic development, the age level that China starts wearing spectacles more and more trends towards becoming younger, and one of them major reason is the sitting posture of people while thinking little of reading, unhygienic with eye.When reading, classmates tend to lie prone unconsciously and on desk, read a book or write, and this eyesight, vertebra and body development to student has great harm.Therefore designing such sitting posture reminder has the certain significance.At present more existing technical schemes, conclude and be mainly divided into following two classes:
The first kind is sitting-posture correction device.If the patent No. is CN2181410, CN215186, CN103126369A etc.This type of apparatus for correcting generally has rigid parts to force user to sit up straight, and has compressing sensation while use on the one hand, once apparatus for correcting unloads on the other hand, and the incorrect sitting-pose before probably recovering.
Equations of The Second Kind is sitting posture reminder.These type of works detect user's sitting posture by the whole bag of tricks, will send warning if incorrect, some still needs to contact with human body, as wear-type 93238012.3 (patent No.), supra-aural 201020519097.4 (patent No.), backpack 201220162238.0 (patent No.), infrared facility, as 201220523425.7 (patent No.s).
The utility model belongs to sitting posture reminder, adopts ultrasonic ranging principle, and voice device that can typing sound sends prompting.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of contactless sitting posture reminder in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of sitting posture reminder, this sitting posture reminder comprises supersonic range finder, voice device, liquid crystal and LED display unit, input keyboard, single-chip microcomputer and temperature sensor, and described supersonic range finder, voice device, liquid crystal and LED display unit, input keyboard and temperature sensor are all connected with single-chip microcomputer.
Described supersonic range finder comprises transmitting probe and receiving transducer.
Described voice device and single-chip microcomputer surface are provided with shell, and described supersonic range finder, liquid crystal and LED display unit and input keyboard are positioned at case surface.
Described sitting posture reminder also comprises support and base, and described base rear end and shell base are rotationally connected, and described base front end and support one end are rotationally connected, and the described support other end and inner surface of outer cover are slidably connected.
Described voice device comprises loudspeaker and microphone.
Described liquid crystal and LED display unit comprise LCDs and for showing the LED lamp of multiple color.
Compared with prior art, the utlity model has following advantage:
1) install small and exquisite flexibly, be easy to carry.
2) angle is easily changed, and distance can be established, and the time can determine, and applicability is strong.
3) contactless with user's health, there is no body burden.
4) ultrasonic ranging is simply accurate.
5) voice device can any sound of typing as alarm sound, hommization degree is high.
6) liquid crystal and LED display unit provide animation and optical effect, eye-catching simple and clear.

Wherein: 1, supersonic range finder; 2, voice device; 3, liquid crystal and LED display unit; 4, input keyboard; 5, control module; 6, support; 7, base; 8, temperature sensor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite taking technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of sitting posture reminder, as shown in Figure 1, this sitting posture reminder comprises supersonic range finder 1, voice device 2, liquid crystal and LED display unit 3, input keyboard 4, single-chip microcomputer 5 and temperature sensor 8, and supersonic range finder 1, voice device 2, liquid crystal and LED display unit 3, input keyboard 4 and temperature sensor 8 are all connected with single-chip microcomputer 5.
Supersonic range finder 1 comprises transmitting probe and receiving transducer.
Voice device 2 and single-chip microcomputer 5 surfaces are provided with shell, and supersonic range finder 1, liquid crystal and LED display unit 3 and input keyboard 4 are positioned at case surface.
Sitting posture reminder also comprises support 6 and base 7, and base 7 rear ends and shell base are rotationally connected, and base 7 front ends and support 6 one end are rotationally connected, and support 6 other ends and inner surface of outer cover are slidably connected.
Voice device 2 comprises loudspeaker and microphone.
Liquid crystal and LED display unit 3 comprise LCDs and for showing the LED lamp of multiple color.
Be illustrated in figure 2 the control module frame diagram of sitting posture reminder, single-chip microcomputer 5 is the control module of utility model for this reason, divide rank to be connected with sitting posture reminder each several part, be wherein divided into two-way with being connected of supersonic range finder 1, be connected with transmitting probe and receiving transducer respectively.
Whole device adopts the DC power supply that input voltage range is 4.5V-6V.
Base 7 supports whole sitting posture reminder, the position that base 7 is placed changes the horizontal range of user and sitting posture reminder, and position difference, height difference that support 6 can be sat according to user slide up and down to change supersonic range finder 1 angle by support 6 and shell junction along shell.After the transmitting probe transmitting ultrasonic signal of supersonic range finder 1 contacts with user's forehead, this signal turns back to the receiving transducer of supersonic range finder 1.Single-chip microcomputer 5 is determined the distance of user and sitting posture reminder according to transmitting and the mistiming that receives signal, compare according to this distance and the appropriate distance of the correct sitting posture position setting in advance.If go beyond the scope, control module 5 starts indicating mode, and red LED lamp is bright.For avoiding some emergency case of user to cause indicating mode to be opened, by delay time is freely set, when departing from correct sitting posture, user exceeds after setting-up time, and indicating mode just can be opened.If all remain on the distance range of setting correct sitting posture in setting-up time, control module 5 starts encouraging pattern; Green and yellow LED lamp are bright.By built-in voice device 2 and single-chip microcomputer 5 can any sound of typing as reminding sound and rewarding sound, hommization degree is high.Provide animation and optical effect by liquid crystal and LED display unit 3, eye-catching simple and clear.The appropriate distance that can set suitable correct sitting posture position by input keyboard 4 users, system also has pattern selective; Setting-up time can be set, and system also has pattern selective; Can select to remind sound and reward sound, system also has system sounds selective.User's degree of freedom is large, easy to operate.
Because hyperacoustic speed is relevant to real time temperature, for reducing systematic error, the utility model has added temperature sensor 8.Under zero degrees celsius, the aerial velocity of propagation of ultrasound wave is 331.45m/s, be subject to the impact of the factors such as temperature in air, humidity, pressure due to its speed, wherein be subject to the impact of temperature larger, 1 DEG C of the every rising of temperature, speed will the about 0.6m/s of corresponding increase, requires high occasion to revise it by the method for temperature compensation to distance accuracy.Utilize temperature sensor DS18820 to record temperature T, according to formula c=331.5+0.607T, can determine the velocity of wave under Current Temperatures.After velocity of wave is determined, then according to s=ct/2, calculate actual distance value.
