FIG. 2 shows a table for preventing loss of goods and its system according to an embodiment of the present invention, Fig. 8 is a flowchart for explaining an alarm notification of the device for preventing loss of articles according to the embodiment. Fig.

1, the object loss prevention table (100 or less, table) may include a control unit 110, a pressure sensor 121, a temperature sensor 123, and a gyro sensor 125. [

The control unit 110 may include a processor 111, a memory 113, and a communication module 115.

The processor 111 determines the measurement value sensed by the sensor unit 120 and senses the movement of the objects on the object loss prevention apparatus 100 and transmits a control signal to the communication module 115. The processor 111 may be a CPU, a microcontroller, a digital signal processor (DPS), or the like.

The memory 113 may store the operating system, drivers, application programs, and information collected from the sensor unit 120 required for the operation of the table 100.

The communication module 115 may transmit an alarm notification message to the smart device 200 according to the control signal of the processor 111 to inform the smart device 200 of the loss of the object. Via communication module 115, messages and data, information, and one or more programs (i.e., application code).

The communication module 115 may use the short-range communication for transmitting the alarm notification message. Bluetooth, Radio Frequency Identification (RFID), Ultra Wideband (UWB), ZigBee, or the like can be used as the short range communication technology.

As the pressure sensor 121, any sensor can be used as long as it is a sensor capable of detecting a pressure of a degree that a person presses with a finger.

As the temperature sensor 123, any sensor can be used as long as it can measure the temperature change at room temperature.

The gyro sensor 125 is a sensor used for position measurement and direction setting in a concept using a dynamic motion of a rotating object, and can be used in an object to which movement and rotation are to be measured.

Meanwhile, the controller 110 can determine whether an object exists on the table 100, whether the table 100 is used, whether the table 100 is stolen, and whether notification is transmitted. The operation of the control unit 110 may be described in detail below with reference to the operation of each configuration.

The pressure sensor 121 is provided on the top plate 190 of the table so as to sense an object placed on the table. If the pressure value detected by the pressure sensor 121 is within the preset range, the controller 110 can determine that the object exists on the table.

The control unit 110 may determine that the object on the table 100 has disappeared when the sensed pressure value is out of the preset range in a state where the object is determined to exist on the table 100. [

The temperature sensor 123 may be provided at a position where the temperature of the table top plate 190 can be sensed. The temperature sensor 123 is used to determine that the user is using the table 100. For example, if you continue to use the notebook, heat will be generated due to the operation of the internal devices. Or the temperature of the table 100 may be raised by the body temperature of the user.

Accordingly, the controller 110 can determine that the user uses the table 100 when the temperature value sensed by the temperature sensor 123 rises above the preset range.

The gyro sensor 125 may be provided at a position capable of sensing movement of the table 100. The pressure sensor 121 and the temperature sensor 123 may be provided on the upper surface of the table,

The controller 110 may determine that the table is stolen if the movement of the table is detected by the gyro sensor 125. [

Meanwhile, the control unit 110 may transmit a notification to the smart device 200 informing that the object on the table 100 and the table 100 are stolen.

If the controller 110 determines that the object on the table top 190 has disappeared, the controller 110 may transmit a notification to the smart device 200 indicating that the object has been lost. However, when the user judges that the table 100 is being used, the notification is not transmitted even if it is determined that the object has disappeared.

The user may move the table 100 during use, on the date and time, leaning on the table 100, putting his or her hand on the table 100, or moving the table 100 while using the object on the table 100, It happens.

Accordingly, when the user is using the table, it is determined that the object is lost according to the value detected by the pressure sensor 121, and if the notification is transmitted each time, a lot of unnecessary notifications are transmitted. The controller 110 may determine the temperature sensed by the temperature sensor 123 to determine whether the table 100 is used or not, thereby preventing unnecessary notifications from being transmitted.

The controller 110 may determine that the user is not using the table 100 when the temperature falls below the preset range while the user is judging that the table 100 is being used.

When the controller 110 determines that the user does not use the table 100, if the controller 110 determines that the article on the table 100 has disappeared, the controller 110 can transmit a notification of the loss of the article to the user's smart device 200 have.

In addition, when it is determined that the user is not using the table 100, the controller 110 may transmit the notification to the smart device 200 if the table 100 is determined to be stolen.

Accordingly, it is possible to prevent the table 100 from being stolen, and it is possible to prevent a person who knows the function of the table 100 from stealing the table 100 in order to steal the object.

Referring to FIG. 2, the table 100 according to the embodiment of the present invention may include a control unit 110 inserted into a top plate 190 of a table. Alternatively, the control unit 110 may be inserted into or attached to the leg of the table 100.

The smart device 200 may display the notification transmitted from the control unit 110 on the display and inform the user of the notification sound or the like. The smart device 200 may be a smart phone, a tablet PC, a PDA, or a notebook, but is not limited thereto. The smart device 200 receiving the notification of the table 100 may be a single device or a plurality of devices.

The smart device 200 receiving the notification can be set by the user, and the application can be installed in the smart device 200 for setting.

When the user leaves the preset range with the object 300 in the table 100 and the communication with the control unit 110 can not be established through the application installed in the smart device 200, The smart device 200 can notify the user that the item 300 has been moved through the display of the smart device 200 or a notification sound.

3 is a flowchart illustrating an operation of the apparatus for preventing loss of articles according to an embodiment of the present invention.

Referring to FIG. 3, when an object on the upper plate of the table 100 is sensed (S310), the temperature of the table top plate is sensed (S320) to determine whether the user uses the table 100 (S330)

If the user does not judge that the table 100 is being used (S330: N), it is determined whether there is an item on the table (S340). If it is determined that the item is disappeared, Ali sends a notification.

In addition, it is determined whether the table 100 has been moved (S350). If it is determined that the table has been moved, a notice informing the theft of the table is transmitted to the smart device 200. [

On the other hand, when the user judges that the table 100 is being used (S330: Y), the temperature of the table top is continuously detected (S320). When the user moves the table 100, It is determined whether the above item exists or not (S340), and the smart device 200 can transmit a notification of the loss of the item.

4 is a view for explaining a position of a smartphone to be placed on a top plate in order to examine the number of load cells required for a table having a size of 1 m x 1 m according to an embodiment of the present invention.

The table 100 according to the embodiment of the present invention can measure the load on the object loss prevention table 100 by using the load cell with the pressure sensor 121 and sense that there is an object on the table 100. [

There are various types of load cell, such as beam type load cell, column type load cell, S type load cell, and diagram type load cell depending on the direction and shape of the force. The load cell to be used in an area of a general table which is exerted only in one direction as in the case of the table 100 according to the embodiment of the present invention is preferably a diagram-type load cell.

A process of detecting an object on the table by the load cell will now be described. When the object is placed on the object loss prevention table 100 equipped with the load cell, the load cell is deformed by the load of the object and the strain gauge is deformed at the same time. When the strain gage is deformed, its resistance value changes. At the output terminal, a voltage proportional to the change is output to the resistance value of the strain gauge. In the above process, the load cell is deformed in order to measure the load, but the deformation is so fine that it can not be visually recognized.

In the embodiment of the present invention, a load is measured by using a compact stainless steel compression load cell having a diameter of 19 mm in the form of a diagram on a square table having a size of 1 m x 1 m, and the pressure is sensed. When several load cells are used, it is important to apply a uniform load to each load cell. In order to apply a uniform load, it is preferable to use an upper plate of a material which is bent appropriately.

Experimental Example 1 was carried out in order to determine the preferable number of load cells to be used for sensing the pressure in the 1 m x 1 m table of the size of the top plate 190 according to the embodiment of the present invention.

Experimental Example 1. Accuracy of notification according to the number of load cells

Experiments were carried out by changing the size of the table top plate 190 and the type of the load cell and by changing the number of load cells used. The size of the upper plate 190 was 1 mm x 1 m, and a compact stainless steel compression load cell having a diameter of 19 mm was used.

In Comparative Example 1, one load cell was installed at the center of the table top plate 190. In Comparative Example 2, four plates were placed one by one in the center of a quadrant divided into four equal parts of 50 cm x 50 m. In Comparative Example 3, 9 in the center of a square divided into nine equal parts of 33.3 cm x 33.3 cm, and in Comparative Example 4, 16 pieces were installed one by one in the center of a square divided into 16 equal parts of 25 cm x 25 cm.

5 smart phones are prepared as objects to be detected on the upper plate 190 and one smartphone is placed one by one in the areas A, B, C, D and E shown in FIG. 4, ).

In Table 1, it can be seen that the comparative example 1 in which only one load cell is provided at the center detects four movements of five smartphones while sensing movement of one smartphone. It can be seen that Comparative Examples 2 to 4 detected all the movements of the five smartphones.

In other words, when only one load cell is provided at the center, it can be seen that objects located at the corners of the rectangle can not be detected. In addition, it is understood that when four or more load cells are provided, the movement of the object on the table top plate 190 can be detected regardless of the position of the object on the top plate 190.

Accordingly, it is preferable that the object loss prevention table 100 according to the embodiment of the present invention is provided with four load cells one at a center of a quadrangle divided into quarters of 50 cm x 50 m of the upper plate 190.
