Background
At present, many pupils all begin to appear the eyesight decline, myopia appears, the leading cause all is that there is very big relation with the position of sitting, also there are some position of sitting reminding devices now, but these position of sitting reminding devices all are provided with a distance measuring sensor on the back of the chair usually, do not compare like this, it is inaccurate to measure easily, the wrong report is alert appearing, and mostly all lack distance measuring sensor's protector, if direct outstanding setting, lean on bad when being used easily, if set up when the inboard, when wiping the chair, intake easily, damage the sensor.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned problem comprehensively, especially to the not enough that prior art exists, the utility model provides a based on ultrasonic wave sensing formula position of sitting reminding device.
In order to achieve the above object, the utility model adopts the following technical means:
the utility model provides a based on ultrasonic wave sensing formula position of sitting reminding device, is including the chair body that has the back, the inboard from the top down of back of chair body is provided with the ultrasonic ranging sensor of three equidistance, be provided with the slotted hole that sinks that is used for installing ultrasonic ranging sensor on the back of chair body, it is provided with sensor protector on the slotted hole to sink, the back of chair body is provided with bee calling organ and the controller of being connected with ultrasonic ranging sensor, bee calling organ electricity, be provided with switch button on the controller.
Further, the sensor protector includes the protection section of thick bamboo with heavy slotted hole threaded connection, be provided with the protective cover on the protection section of thick bamboo, be formed with the splendid attire case that is used for the splendid attire protective cover on the controller.
Further, the controller adopts the Arduino singlechip, adopts DC3.7V mains operated.
Further, the DC3.7V power supply is a 3.7V rechargeable battery.
Further, the power switch button is arranged on the side face of the controller.
The utility model has the advantages that:
the utility model discloses simple structure, measure through the ultrasonic ranging sensor of three equidistance, can be more three measured data, ultrasonic ranging sensor gives the controller with measured data transmission, the controller operates signal data, just can report to the police when three measured value error all exceeds a definite value, controller control buzzer reports to the police, it is more accurate to measure, reduce the alert probability of wrong report, and be provided with sensor protector, can play fine guard action to the sensor, can not leaned on badly, not the time spent at ordinary times, can also prevent the entering of dust from damaging the sensor, also can prevent to clean the chair time, rivers go into in the mounting groove, damage the sensor.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;
fig. 3 is a control schematic of the present invention;
fig. 4 is a schematic view of the working process of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.
As shown in fig. 1-3, this embodiment provides a position of sitting reminding device based on ultrasonic sensing formula, including the chair body 1 that has the back, the inboard from the top down of back of chair body 1 is provided with the ultrasonic ranging sensor 2 of three equidistance, be provided with the heavy slotted hole 101 that is used for installing ultrasonic ranging sensor 2 on the back of chair body 1, be provided with sensor protector on the heavy slotted hole 101, the back of chair body 1 is provided with bee calling organ 3 and the controller 4 of being connected with ultrasonic ranging sensor 2, bee calling organ 3 electricity, be provided with switch button 5 on the controller 4. The sensor protection device comprises a protection barrel 102 in threaded connection with a slotted hole 101, a protection cover 103 is arranged on the protection barrel 102, a containing box 401 for containing the protection cover 103 is formed on the controller 4, and the protection cover is detached and placed in the containing box when in use. The controller adopts Arduino singlechip, adopts DC3.7V mains operated. The DC3.7V power supply is a 3.7V rechargeable battery. The power switch button 5 is arranged on the side surface of the controller 4.
The utility model discloses simple structure, measure through the ultrasonic ranging sensor of three equidistance, can derive three measured data, ultrasonic ranging sensor gives the controller with measured data transmission, the controller operates signal data, just can report to the police when three sensor measuring error exceeds a definite value, the start at first gets into standby state, press until the button, carry out initial distance after pressing the button and detect, distance value is once gathered every 100 milliseconds during, and average with historical data, loosen until the button, finally obtain the initial reference distance between user and the chair back of the body after average many times. The chair enters a formal working state after the button is released, once the distance between the current user and the back of the chair is detected to be greater than the reference distance, in order to avoid misjudgment of a critical state, the judgment is carried out by using the reference distance plus 5cm as a standard, namely the sitting posture is determined to be forward inclined, different numerical values are set according to different people for the reference distance, in addition, in order to avoid that the user always detects the exceeding of the distance when temporarily leaving the chair, and unnecessary alarm is caused, the scheme also adds a condition that the actual measurement distance is less than 100cm, when the actual measurement distance is greater than 100cm, the user is determined to leave the chair instead of the abnormal sitting posture, when the abnormal sitting posture is detected, the controller controls the buzzer to alarm, the measurement is more accurate, the probability of false alarm is reduced, and the sensor protection device is arranged, the sensor can play a good, when the device is not used at a flat time, the device can prevent dust from entering and damaging the sensor, and can also prevent water from flowing into the mounting groove and damaging the sensor when the device is used for wiping a chair.
The present invention is illustrated by way of example and not by way of limitation. It will be apparent to those skilled in the art that other variations and modifications of the present invention can be made in light of the above teachings, and it is not necessary or necessary to exhaustively enumerate all embodiments herein, and it is intended that all such obvious variations and modifications are within the scope of the present invention.
