The output unit 105 may output various data measured through the device. According to an embodiment, the output unit 105 may output the vertical height data of the object, and if the object is a human, it may output the user's identification information and the growth management data received from the height management server 300 . For example, the output unit 105 may output the height data calculated through the controller 104 together with the user's identification information, such as “Gildong Hong, 14 years old, male, height 165cm”.

The output unit 105 may receive a user's touch input, and in this case, the input unit 103 and the output unit 105 may be formed of one physical component. Accordingly, the output unit 105 may include various sensing means capable of recognizing various inputs generated in an area displaying an image.

According to an embodiment, when the smart height measuring apparatus 100 and the user device 200 are connected and operated, the functions of the input unit 103 and the output unit 105 may be performed by the user device 200 . For example, according to a measurement signal transmitted from the user device 200, the smart height measurement apparatus 100 may measure the vertical distance between the object and the structure, and the communication unit 101 transmits the measured value to the user device ( 200). The control unit 104 is operatively connected to the communication unit 101, the storage unit 102, the input unit 103 and the output unit 105, so that the overall The operation may be controlled, and various commands may be executed to calculate the vertical height of the object by driving an application or program stored in the storage unit 102 .

According to an exemplary embodiment, before calculating the vertical height of the object, the controller 104 may check whether the reference distance currently stored in the storage unit 102 is to be used from the user through the input unit 103 . If it is determined that the user will use the reference distance stored in the storage unit 102 , the controller 104 may perform a series of operations for calculating the vertical height of the object. Conversely, when it is confirmed that the user does not use the reference distance stored in the storage unit 102 , the control unit 104 determines whether to measure the reference distance from the user through the input unit 103 or directly input the reference distance. can be checked Accordingly, when measuring the reference distance, the controller 104 may determine the vertical distance measured while the device is seated on the floor as the reference distance according to a user's manipulation.

After setting the reference distance in various ways, the control unit 104 confirms that the device is seated on the upper surface of the object according to the user's manipulation, and measures the vertical distance between the object and the structure through the distance measurement unit 120 . Also, the vertical distance may be subtracted from the reference distance, and the subtracted value may be determined as the vertical height of the object. For example, the distance measuring unit 120 may be a laser sensor, and is composed of a laser transmitter and a laser receiver, and as the laser receiver receives a laser transmitted from the laser transmitter and reflected on a specific object, the object and the structure The vertical distance can be measured.

On the other hand, in the case of the smart height measuring device 100, since the device itself does not operate in a fixed state on the floor, if the user does not properly seat the device on the upper surface of the object, an error may occur in the calculated value. there is. Here, correctly seated means that the floor 111 constituting the device and the floor on which the object is disposed are parallel to each other. For example, when the object is a human, the device may not be properly seated on an uneven head.

Accordingly, it is possible to measure the angle between the device 100 and the ground through a sensor (not shown) additionally built into the smart height measuring device 100, and the controller 104 determines that the angle is a constant value of +/-. (If the device is not placed parallel to the ground), it can be controlled to output an alarm. Here, the alarm may include various types of alarms recognizable by a user, such as a visual or audible alarm or a vibration alarm.

On the other hand, depending on the user's setting, the arrangement angle of the device may have a predetermined allowable range (a preset angle range), and when the arrangement angle of the device is within the allowable range, the control unit 104 generates an alarm as follows. The angle can be corrected.

5A and 5B are schematic diagrams for explaining a method of measuring a vertical distance in a smart height measuring device according to an embodiment of the present invention.

5A and 5B , the controller 104 may correct the calculated vertical height of the object according to Equation 1 below. Here, A' is the distance calculated as the device itself is not properly mounted on the floor, x° is the angle of inclination of the device forward and backward as shown in FIG. 5A, and y° is the angle of inclination of the device to the left and right as shown in FIG. 5B, k denotes the distance from the measurement reference floor to the center of the bottom of the device, and A denotes the vertical distance corrected through the above-described variables and constants. As such, through [Equation 1], the inclination of the device may be adjusted within a range of approximately ±5°, and the previously calculated vertical height of the object may be corrected to match the corrected value.

[Equation 1]

According to an embodiment, the controller 104 may correct the vertical height of the object through an average calculation method. Specifically, when a user input is sensed through the button unit 135 for a preset time, the control unit 104 may measure the distance between the lower surface of the structure and the upper surface of the object multiple times, and the distance measured multiple times can be individually subtracted from the reference distance to calculate the average value of the subtracted values. The controller 104 may determine the calculated average value as the vertical height of the object, and may obtain the vertical height of the object by minimizing an error range even if the user does not properly seat the device on the object.

In addition, the controller 104 may determine a distance having the shortest value among the distances measured a plurality of times by the distance measuring unit 120 as the vertical height of the object.

According to another embodiment, the control unit 104 may allow the user to properly seat the device on the upper surface of the object through a vertical correction device (not shown) additionally provided in the smart height measuring device 100 . For example, the vertical correction device may be a mechanical device such as an actuator, and may seat the device parallel to the ground on the upper surface of the object, which is usually curved. The smart height measuring apparatus according to the description has been described, and hereinafter, a method for measuring the height of an object using the smart height measuring apparatus 100 will be described.

6 is a schematic flowchart of a growth management method according to an embodiment of the present invention.

Referring to FIG. 6 , the smart height measuring apparatus 100 determines a reference distance through the user before calculating the vertical height of the object ( S110 ). Specifically, the smart height measuring apparatus 100 may output reference distance data and determine whether to use a reference distance stored in advance for the user.

If it is determined that the user will use the pre-stored reference distance, the smart height measuring apparatus 100 may perform a series of operations for calculating the vertical height of the object.

Conversely, when it is determined that the user does not use the pre-stored reference distance, the smart height measuring apparatus 100 may determine whether to measure the reference distance or directly input the reference distance to the user.

In this regard, Figure 7 is a schematic diagram for explaining the height measurement method of the smart height measurement device according to an embodiment of the present invention.

Referring to FIG. 7 , when the reference distance is newly measured in a situation where the height of a child is measured indoors, the smart height measuring device 100 made of a triangle may be seated on the floor according to the user's manipulation. . The smart height measuring apparatus 100 may confirm that it is seated on the floor, measure the vertical distance from the floor to the ceiling, and determine the measured vertical distance as the reference distance H1.

Alternatively, when it is confirmed that the reference distance is to be input from the user, the smart height measuring apparatus 100 is a reference distance H1 for measuring the vertical height of the object from the input means provided in the apparatus itself or the user device 200 . can be decided with

After step S110, the smart height measuring apparatus 100 measures the remaining distance between the object and the structure (S120). For example, the structure in FIG. 6 may be a ceiling, and the smart height measuring device 100 checks that it is seated on the user's head, and measures the residual distance H2 from the tip of the head to the ceiling surface. can do.

In addition, the smart height measuring apparatus 100 may correct the vertical height of the object according to the following [Equation 1] in consideration of the case where the apparatus is not properly seated on the upper surface of the object. That is, through [Equation 1], the inclination of the device may be adjusted within a range of approximately ±5°, and the previously calculated vertical height of the object may be corrected to match the corrected inclination value.

[Equation 1]

where A' is the distance calculated as the device itself is not mounted correctly on the floor, x° is the tilt angle of the device back and forth, y° is the tilt angle of the device left and right, and k is the device's tilt angle from the floor to which it is measured Means the distance to the center of the floor.

In addition, the smart height measuring apparatus 100 may correct the vertical height of the object through an average calculation method. Specifically, when a user input is detected through the button unit 135 for a preset time, the smart height measuring apparatus 100 may measure the distance between the lower surface of the structure and the upper surface of the object multiple times, and multiple times By individually subtracting the measured distance from the reference distance, an average value of the subtracted values can be calculated. The smart height measuring apparatus 100 may determine the calculated average value as the vertical height of the object, and even if the user does not properly seat the device on the object, the vertical height of the object may be obtained by minimizing the error range.

After step S120, the smart height measuring apparatus 100 calculates the difference between the reference distance H1 and the residual distance H2, and determines the calculated value as the vertical height of the object (S130). According to an embodiment, when the smart height measuring device 100 receives the reference distance H1 from the user in step S110, the vertical length H3 of the device along with the residual distance H2 is calculated from the reference distance H1. It may be subtracted, and the subtracted value may be determined as the vertical height H4 of the object.

According to another embodiment, when the smart height measuring device 100 measures the reference distance H1 in step S110, the vertical length H3 of the device is already excluded from the reference distance H1 and the remaining distance H2. Therefore, the “reference distance (H1)-residual distance (H2)” value may be determined as the vertical height H4 of the object.

After step S130, the smart height measurement device 100 provides the determined vertical height H4 through the output unit (S140). For example, when the smart height measurement apparatus 100 is provided with a visual or auditory output device, the vertical height H4 can be visually/auditly output, and the vertical height H4 through the user device 200 . ) can also be printed.

In addition, the vertical height (H4) determined in step S140 may be transmitted to the height management server 300, the smart height measurement device 100 data for growth management of the object (child) from the height management server 300 can receive

So far, the growth management method according to an embodiment of the present invention has been described. According to the present invention, the height of the user measured through the smart height measurement device 100 is automatically recorded, and by providing the user with a management method of the growth period based on this, the user is a growth management expert providing one-on-one consulting and You can enjoy the same service.
