Description

A kind of posture monitoring device based on high deformation strain gauge transducer
Technical field
The present invention relates to sensor application field, more particularly to a kind of posture monitoring based on high deformation strain gauge transducer Device.
Background technology
Teenager tends not to pay attention to well to keep correct figure among studying and living, and parent and teacher It can not all the time keep and remind at one's side, the time is near-sighted and bow-backed once growing formation.Myopia and hunchback directly affect body aesthetic feeling, Some even result in physical abnormality, damage teen-age self-confidence.
Moreover, as rhythm of life is accelerated and operating pressure increasingly increases, increasing adult needs to grow Time faces computer, because abnormal sitting posture is true, the symptoms such as nape aching usually occurs, and its essence is because incorrect sitting-pose causes neck Vertebra suffers oppression for a long time, causes cervical vertebra chronic strain, results even in the generation of the illnesss such as scapulohumeral periarthritis and cervical spondylopathy.
At present, many technologies also are used among to the monitoring of posture, most common on the market is exactly " BABAKA ". Brace and waistband is made using elastic fabric in " BABAKA ", is worn on user, forcibly allows user to protect by external force Hold correct posture.The defects of product is:If the elastic dynamics of " BABAKA " is excessive, the discomfort of user can be caused;Such as Korean pine clamp force is spent small, and the effect of correction is less obvious;Meanwhile the price of " BABAKA " is higher, specification is larger, wearing inconvenience and Influence overall appearance.Also some relatively common monitoring devices are a kind of intelligent waistbands for being entangled in loins, and it is opened by mercury Peripheral circuit is connect outside the Pass, and when the sitting posture of user is nonstandard, the mercury in mercury tube will be rolled into one end of pipe, make alarm electric Road is connected, and alarm will remind user to adjust sitting posture.The defects of product is:Mercoid switch sensitivity is too high, somewhat dynamic Alarm will once be sent, often send false alarm, once and improper use cause mercury tracheal rupture, human body can be good for Health damages.
The content of the invention
The present invention discloses one kind and is based on high deformation strain-type to overcome at least one defect described in above-mentioned prior art The posture monitoring device of sensor.The device has that wearing comfort, power consumption are relatively low, size is compact and lower-cost feature, fits Various people are closed, and suitable for all kinds of daily routines, can effectively monitor and help user to correct incorrect appearance in time Gesture.
To achieve these goals, the technical solution adopted by the present invention is as follows:
A kind of posture monitoring device based on high deformation strain gauge transducer, including detection unit, reminding unit, control list Member and display unit;Wherein the input of the output end of detection unit and control unit connects, an output termination of control unit The input of reminding unit, the another output termination display unit of control unit;
The detection unit is high deformation strain gauge transducer, including high the deformation foil gauge and induced electricity being connected in series Road;
Detection unit gathers the bending data at user back in real time, and is sent to control unit, and control unit is converted After voltage signal and to be analyzed, when acquired magnitude of voltage is less than default voltage threshold and voltage signal is lasting When duration reaches preset duration, then control reminding unit to send alarm signal and remind user to correct posture;Control unit is real simultaneously When the bending data of acquisition be sent to display unit shown.
When in use, detection unit is fixed on the back of user to above-mentioned monitoring device, when the back of user bends It can deform upon high deformation foil gauge, so as to cause the resistance of high deformation foil gauge to change, can be incited somebody to action by control unit The change in resistance of high deformation foil gauge is converted into the change of voltage, can will be not easy flexes information conversion measured directly whereby To be easy to magnitude of voltage measured directly.
Meanwhile above-mentioned monitoring device is when in use, three kinds of situations can be judged.The first, when the posture detected When data are more than predetermined threshold value, it is determined that user's posture is correct, and monitoring device continues to monitor the gesture data at user back;Second Kind, when the gesture data detected is less than threshold value, illustrate that user is likely to occur incorrect posture, if the data detected Duration be less than threshold value preset duration when, illustrate user be intended merely to activity one lower body and somewhat change lower posture, Monitoring device continues to monitor the gesture data at user back;The third, when the gesture data detected is less than threshold value, and continues Between when reaching the preset duration of threshold value, illustrate that the posture of mistake occurs in user, the control signal of control unit output is high electricity It is flat, so as to control the posture that reminding unit reminds user's (vibration) to correct mistake, after user's correction posture, the data that detect More than threshold value, control signal is low level, closes prompting function (stopping vibration), and monitoring device continues to monitor the appearance at user back Gesture data.
In use, control unit sends the gesture data detected to the display unit of user in real time, for Real-time posture situation is checked at family, and display unit can be utilized to continue to obtain the analysis of science and more personalized in more detail It is recommended that.
Preferably, described high deformation foil gauge uses silicone-nickel nano composite material;Select copolyesters silicone material Material, and nickel nano chain (Nickel Nanostrands) and nickel-coated carbon fibers (Nickel Coated Carbon are added wherein Fiber), the deformation suffered by foil gauge is bigger, and its resistance is smaller;The deformation range of the foil gauge sensing of this material is larger, together When can keep good electric conductivity and sensitivity, and cost is relatively low.
Described detection unit and reminding unit is integrated on kinesiology tape cloth.When in use, the high deformation in the present invention Then kinesiology tape cloth is attached to portion of the user behind among two pieces of shoulder blades by foil gauge silica gel packaging on kinesiology tape cloth Position, and close to the recess of vertebra, so not only the flexes of user effectively can be accurately detected, and can effectively improve Reliability of the device in long-time use;Control unit is arranged in a housing, and is used on housing with clip or safety pin In being fixed on the waistband of user, in so avoiding the monitoring device to caused by user it is uncomfortable, but also carry High Consumer's Experience.
Preferably, described sensor circuit is divider resistance or Wheatstone bridge divider.
Preferably, described control unit includes microcontroller, and be connected with microcontroller memory module, channel radio Believe module and power module, the signal that the detection unit collects is transferred to microcontroller, and microcontroller is to detection unit Input voltage is provided, the data collected be processed and stored in memory module, and controls reminding unit to remind user The posture of mistake is corrected, while the bending data of acquisition are sent in real time by display unit by wireless communication module and shown Show.
Preferably, described microcontroller is Arduino, RFduino or simblee;Described memory module is fast Flash memory or random access memory;Described wireless communication module be bluetooth, Wi-Fi module, 2G, 3G, 4G communication, ZigBee or GPRS;Described power module is alkaline battery or button cell.
