It shows how each sensor module is connected to the multiplexer and the multiplexers are connected back to the adapter. Finally, the service can be connected to Raspberry Pie 3.

As shown in FIG. 3, each multiplexer enters one analog pin, three digital pins, one 5V power supply, and three GNDs. You can receive 8 analog values per multiplexer. A total of eight of these milltaplexers are formed and finally a circuit capable of receiving 64 analog signals is formed. In addition, each multiplexer is equipped with a 10K fixed resistor to the input signal value to prepare to receive the sensor value. There are 8 resistors per multiplexer, so a total of 64 resistors are present in the circuit. Each sensor in the sensor module is mapped to one resistor and the other line of the sensor is mapped to a pin of 5V to enable the sensor to operate.

The relationship between Raspberry Pi, Arduino mega 2560 R3 (hereinafter, referred to as 'Arduino') and sensors (part of the devices used in one embodiment of the present invention with respect to the posture correction solution hardware configuration and algorithm) is shown in FIG.

The product of the posture correcting system according to the present embodiment is the red boundary of FIG. 2 and is an IOT device composed of 64 sensors, Arduino, and Raspberry Pi 3. When 64 sensors transmit analog values to Arduino, the Arduino Mega converts them to digital values between 0 and 1023 and transfers the data to Raspberry Pi 3 using serial communication. The server can use these data to accumulate in an external Mongolian database or to provide the user with the current posture.

Inside the product of the posture correction system, data is received between Arduino and RaspberryP3 using serial communication and can be used by each user through the wireless network. Devices within the same network can access the RaspberryP3 web server to receive current status and reports, and RaspberryP3, which is connected to the Internet via a router, can send measurements to the server.

As a database that can process big data of sensor value is needed, data can be collected and processed using Mongo DB, which is a big data base, and can be installed on an independent server. Express, which also operates within Raspberry Pie 3, is a web application server that can be used to present data present in the form of a web page.

Arduino collects a number of analog sensor values using a sensor installed in the cushion. Here, Arduino converts analog sensor value to digital value 0 ~ 1023, uses 8 analog sensor pins, connects 8 multiplexers using 24 digital pins, runs each multiplexer every 33 msec, Lt; / RTI > At this time, all sensor values can be received every about 0.5 sec.

Raspberry Pi runs an Express server using Node.js to provide data via the Web. Here, Raspberry Pi can refine the values received from Arduino, analyze it through its own algorithm, and provide the analyzed data to users through web or app. In Node.js, the following Open Souce is enabled as a Server-Side platform. The Play Canvas showed the chair / person and is used to visualize the data by posture. Canvas JS is used to implement various graphs and reports. Socket IO is used to receive and receive data in real time.

The following is an algorithm implemented by the development team to provide the service, mapping all 64 sensors to coordinates, and obtaining the average of the coordinates of valid sensors. How to distinguish the incorrect posture is also mapped to the coordinates, so it can be judged in the manufactured product.

This sensor unit combines 64 sensor modules consisting of pressure sensitive conductive film (1), sponge (2) and copper tape (3) as interior and sensor in the cushion. Do.

And the cushion shell with sensor structure of the sensing part can be used as various kinds if it is the size of the cover material to protect the sensor.

FIG. 5 is a diagram illustrating an arrangement of a sensor configuration of a sensing unit that enters a posture correcting cushion according to an embodiment of the present invention.

The sensor mapping unit 200 maps the 64 sensors to the coordinates for various operations in FIG.

The operation unit 300 can obtain a 'center point' representing the points mapped by the sensor mapping unit 200 by the formula (1). Sensors having a value at this time indicate sensors having a constant value (e.g., a value of 100 or more) sensed when the user sits on the cushion.

Since the center point value is different for each user of the cushion, it is necessary to set the reference point for each user. The 'distance' for calculating how far away from the posture is can be obtained by [Equation 2] as follows.

FIG. 6 illustrates an embodiment of a posture correction system according to an embodiment of the present invention.

As shown in Fig. 6, the cushion made on the chair was placed so that the measurement was actually possible. Here, we confirmed that the data is received through the current Web page.

7 to 9 are illustrations showing results according to the attitude of the user using the product according to the present embodiment.

Fig. 7 shows a rightward inclined posture, Fig. 8 shows a normal posture, and Fig. 9 shows a leftward inclined posture state. As the background color of the 3D image becomes redder, it becomes noticeable that the posture is greatly changed, and this visual expression can be used to surely inform the user.

The posture correction system and the method according to an embodiment of the present invention are based on the assumption that modern people sit and work for a very long time. Based on this, it is possible to use the web and the Android application by using the pressure applied to the cushion when the user is sitting So that it can be easily monitored and guided to have a correct sitting posture.
