1 and 2 are diagrams showing a blood alcohol concentration measurement system 100 according to an embodiment of the present invention.

1 and 2, the blood alcohol concentration measuring system 100 includes a coaster 110 and a user terminal 120. For example, the blood alcohol concentration measuring system 100 may be implemented in a bar such as a hob house, and in particular, the coaster 110 may be installed on a table of the bar.

In the blood alcohol concentration measurement system 100, the cup support 110 and the user terminal 120 may be connected wirelessly, for example, may be connected via Bluetooth communication and Wi-Fi communication.

The coaster 110 includes a battery 112, a weight sensor 114, and a network module 116. The battery 112 provides power to the coaster 110 and, in one embodiment, may be detachably coupled at the bottom of the coaster 110. The weight sensor 114 measures the weight of the cup placed on the coaster 110 and, in one embodiment, may be measured periodically to operate at low power. The network module 116 may provide the user terminal 120 with weight data measured by the cup support device 110 using wireless communication.

The user terminal 120 may correspond to a computing device connected to the cup support device 110 and may be implemented as, for example, a smartphone or a wearable device. In one embodiment, the user terminal 120 may determine the amount of alcohol and blood alcohol concentration of the user based on the weight data received from the coasting device (110). In one embodiment, the user terminal 120 may receive a physical condition and drinking conditions, such as the user's current situation, through which it is possible to more accurately determine the amount of alcohol drinking and blood alcohol concentration of the user.

3 is a block diagram illustrating a blood alcohol concentration measurement process performed by the user terminal in FIG. 1.

Referring to FIG. 3, the user terminal 120 includes a weight receiving unit 310, a drinking amount measuring unit 320, a user state estimating unit 330, a blood alcohol concentration determining unit 340, a memory unit 350, and a display unit ( 360 and the control unit 370.

The weight receiver 310 performs a function related to the reception of weight data measured from the cup support 110. The weight receiver 310 may set a reception period at the next specific time based on the received average weight change amount. The reception period setting method may be expressed by Equation 1 below.

Here, Tn + 1 represents the next reception period, Wmax represents the maximum weight within the specific time, A represents the average weight change amount within the specific time, and Tn represents the current reception period. In one embodiment, the user terminal 120 determines that the user is actively drinking if the average weight change A during the Tn measured by the cup support device 110 is large, and sets the measurement cycle of Tn + 1 quickly. If the average change A during the Tn measured by the cup support device 110 is very small, the user terminal 120 determines that the user is drinking and sets the measurement period for Tn + 1 slowly. The criterion of average weight change A corresponds to Wmax, the maximum weight in Tn. This process can achieve the effect of minimizing the power usage of the coasting device (110).

The drinking amount measuring unit 320 may measure the drinking amount of the user based on the weight data received from the coaster 110. When the weight of the wine glass received from the cup holding device 110 is reduced, the user terminal 120 determines the weight reduction amount of the wine glass as the amount of drinking of the user. In addition, the user terminal 120 may receive whether the estimation is reversed from the user. For example, the user terminal 120 may be a wine glass even if the user has not drunk, such as a user pours alcohol or someone other than the user drinking alcohol on the cup support device from the data measured by the cup support device 110. When the weight loss occurs, if the user inputs the decrease amount can be excluded from the drinking amount calculation.

The user state estimator 330 may estimate the current state of the user based on at least one of a physical condition and a drinking condition received through the user terminal 120. The user terminal 120 may receive a user's gender and weight, which are physical conditions, from the user. Since the blood alcohol concentration calculation formula may show a difference in the result value according to gender and weight, the blood alcohol concentration measurement system 100 may more accurately determine the blood alcohol concentration through such information input. Drinking conditions may include the type and brand of alcohol the user is drinking. The user terminal 120 may reflect the difference in alcohol content according to the types and brands of liquors such as shochu, beer, whiskey, and wine in the blood alcohol concentration measurement. In one embodiment, the user terminal 120 may receive an input of the type and brand of alcohol from the user, so that the user terminal 120 may determine the information of the currently drinking alcohol of the user. In addition, the user terminal 120 may receive input again the type and brand of alcohol when the type of alcohol that the user has been drinking. If there is no input for the type and brand of alcohol from the user, the user terminal 120 may determine the type of alcohol and the alcohol content based on the weight data received from the coaster 110.

Finally, the user terminal 120 may reflect the dynamic threshold time from the determination point in the drinking amount calculation process. When the user terminal 120 detects that there is no change in the amount of drinking in the weight data received from the cup support device 110 for about several minutes, the user terminal 120 determines that the user rests for a while. When the user's drinking is started again later, the user terminal 120 may reflect the specific time that the user has not been drinking as the dynamic threshold time.

The blood alcohol concentration determining unit 340 may determine the final blood alcohol concentration of the user by identifying the amount of alcohol measured by the user state estimating unit 330, the physical information of the user, the drinking information, and the dynamic threshold time. The method of determining the final blood alcohol concentration may be expressed as in Equation 2.

Here, B means the final blood alcohol concentration, Bn-k, Bn-k + 1 is the blood alcohol concentration, tn-k, tn-k reflecting the dynamic threshold times reflected in the previous user blood alcohol concentration, respectively +1 is the time elapsed from the determination points of the previous user blood alcohol concentration, Vn is the currently measured drinking amount, Cn is the blood alcohol concentration currently measured, and Bn is the previous user blood alcohol concentration. α represents 1 if there is a dynamic threshold time in the previous calculation of the user's blood alcohol concentration, and 0 otherwise. In one embodiment, if the user state estimator 330 detects the dynamic threshold time, the user terminal 120 may estimate the blood alcohol concentration by reflecting the respective dynamic threshold times in the measured drinking amount, the user state estimator If the 330 does not detect the dynamic threshold time, the user terminal 120 determines that the user has continuously drunk, and may determine the blood alcohol concentration according to the previous drinking amount and alcohol content.

The memory unit 350 may be implemented as a volatile or nonvolatile memory, and may store weight data received from the cup support 110 which is data required by the user terminal 120 of the blood alcohol concentration measurement system 100. Used.

The display 360 may show a drinking amount and a blood alcohol concentration to the user through the user terminal 120. In addition, the display 360 may receive a physical condition, a drinking condition and a desired drinking amount from the user terminal 120.

The controller 370 controls the overall operation of the user terminal 120, the weight receiver 310, the drinking amount measuring unit 320, the user state estimating unit 330, the blood alcohol concentration determining unit 340, and the memory unit 350. ) And the control flow or data flow between the display unit 360.

In FIG. 5, the user terminal 120 may provide a connection setting interface 500 for connection with the cup support device 110.

The user terminal 120 receives weight data from the cup support 110 when the connection with the cup support device 110 is completed, and stores it in the memory of the user terminal 120 (step S420). Here, the user terminal 120 may know the amount of reduction of the weight data received from the coasting device 110. In addition, the user terminal 120 may determine the reception cycle frequency during the next specific time according to the average weight change amount per specific time of the weight data.

When the measurement value is received and stored in the memory, the user terminal 120 analyzes the drinking amount of the user through the stored weight data (step S430). At this time, the user terminal 120 may determine the amount of drinking of the user based on the amount of weight reduction stored in the memory.

The user terminal 120 determines the blood alcohol concentration based on the weight change amount through the weight data received from the cup support device 110, and the information received from the user terminal 120 (step S440).

The user terminal 120 checks whether there is transmission of the network from the cup support device 110 (step S442).
