[0011] The alcohol testing device 100, the alcohol testing system 10, and the alcohol testing method according to the present embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios of the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios. In addition, in the following description of the drawings, the same or similar parts are given the same or similar reference numerals.

[0012] (Configuration of alcohol testing system 10) FIG. 1 is a diagram showing a configuration of an alcohol testing system 10 according to this embodiment. As shown in FIG. 1, the alcohol testing system 10 includes an alcohol testing device 100 and an alcohol checker 300. The alcohol testing system 10 may also include an administrator terminal 30 for an administrator. The alcohol testing system 10 may also include an on-board device 200 of a vehicle 20. In the alcohol testing system 10, the alcohol testing device 100, the on-board device 200, and the administrator terminal 30 are capable of communicating with each other via a network 40. The network 40 may be a mobile phone line.

[0013] The alcohol testing system 10 is a system that measures and tests (checks) the alcohol concentration in the breath by an alcohol checker 300 before driving in order to prevent the driver of a vehicle 20 from drinking and driving. In the alcohol testing system 10 according to this embodiment, if the alcohol concentration in the breath of the driver is higher than a predetermined threshold, the alcohol testing device 100 controls the on-board device 200 of the vehicle 20 so that the driver 32 cannot drive the vehicle 20. In the alcohol testing system 10, the administrator 31 can check the test results of the alcohol testing device 100 via the administrator terminal 30.

[0014] Fig. 2 is a diagram for explaining the breathalyzer 300 according to this embodiment. The breathalyzer 300 shown in Fig. 2 includes an alcohol concentration measurement unit 310, a camera 320, a monitor 330, a power switch 340, and a recording switch 350. The breathalyzer 300 may also include a communication SIM 360.

[0015] The alcohol concentration measurement unit 310 has a function of measuring the alcohol concentration by the driver blowing (exhaling) into the vehicle. The camera 320 has a function of photographing the face of the driver, including the area around the mouth, during the alcohol check in response to pressing of a recording switch 350 described below. That is, the camera 320 photographs the situation in which the driver 32 is obtaining alcohol concentration information by the alcohol concentration measurement unit 310, and obtains the image data.

[0016] The monitor 330 displays the measured alcohol concentration. The driver presses the power switch 340 to start up (power on) the alcohol checker 300. In addition, pressing the power switch 340 while the alcohol checker 300 is running stops the operation of the alcohol checker 300 (power off).

[0017] When the driver presses the record switch 350, an image of the driver is captured by the camera 320. When the driver presses the record switch 350, the alcohol concentration measurement section 310 is enabled.

[0018] Furthermore, in this embodiment, the record switch 350 has an authentication function. For example, the authentication function may be a fingerprint authentication function. In this case, the record switch 350 identifies the driver 32 based on the fingerprint of the driver 32. That is, in this embodiment, the record switch 350 is a switch that activates the alcohol concentration measurement unit 310 and the camera 320, and is a switch that can obtain authentication information of the driver 32. For example, in the authentication function according to this embodiment, if it is possible to authenticate that the user who pressed the record switch 350 is the driver 32, the alcohol concentration measurement unit 310 and the camera 320 may be configured to be enabled.

[0019] When the driver presses the record switch 350 of the alcohol checker 300, the driver's authentication information is acquired. When the driver presses the record switch 350 of the alcohol checker 300, the camera 320 captures information about the driver's face, including the area around the mouth, and image data is acquired. When the driver presses the record switch 350 of the alcohol checker 300, the alcohol concentration measurement unit 310 is enabled and the alcohol concentration of the breath blown by the driver is measured.

[0020] The driver's authentication information, image data, and alcohol concentration measurement result acquired by pressing the record switch 350 are sent to the alcohol testing device 100 via the communication SIM 360. Note that in the alcohol testing system 10, the authentication information, image data, and alcohol concentration measurement result may be sent to the alcohol testing device 100 via a communication function of the vehicle-mounted device 200.

[0021] In this embodiment, the communication function of the breathalyzer 300 including the communication SIM 360 corresponds to a transmission unit. That is, the transmission unit has a function of transmitting the alcohol concentration information, image data, and authentication information acquired by the alcohol concentration measurement unit 310, the camera 320, and the recording switch 350 to the breathalyzer 100.

[0022] (Configuration of the vehicle-mounted device 200) Fig. 3 is a block diagram showing the configuration of the vehicle-mounted device 200 according to this embodiment. As shown in Fig. 3, the vehicle-mounted device 200 includes a CPU 210. The vehicle-mounted device 200 also includes a speed signal IF 231, an engine signal IF 232, a GPS IF 233 (Global Positioning System), an external input IF 234, and a sensor signal IF 235. The vehicle-mounted device 200 also includes a wide-area communication module 241, a non-volatile memory 242, a volatile memory 243, an SD card 244, a SW input unit 245, and an LCD 246 (Liquid Crystal Display).

[0023] The CPU 210 executes pre-installed programs to realize various functions required for the vehicle-mounted device 200. The main operations of the CPU 210 will be described later.

[0024] The speed signal IF 231 converts a predetermined vehicle speed signal output from the vehicle side into a signal suitable for input processing by the CPU 210. The CPU 210 can grasp the traveling speed and traveling distance of the vehicle 20 by monitoring the number of pulses and the signal period of the vehicle speed signal.

[0025] The engine signal IF 232 converts a predetermined engine rotation signal output from the vehicle side into a signal suitable for input processing by the CPU 210. The CPU 210 can grasp the engine rotation speed (rpm) by monitoring the number of pulses and the signal period of the engine rotation signal.

[0026] The GPSIF 233 is used to input a signal from a GPS receiver (not shown) to the CPU 210. The GPS receiver receives radio waves from a plurality of GPS (Global Positioning System) satellites and can calculate the current position of the vehicle 20, which is the reception point. The CPU 210 can obtain information on the current position from the GPS receiver via the GPSIF 233.

[0027] The external input IF 234 converts a predetermined external signal into a signal suitable for input processing by the CPU 210. For example, a signal indicating a gear position is input as the predetermined external signal. Also, a signal indicating the magnitude of acceleration applied to the vehicle 20 can be input to the external input IF 234 as an external signal. Also, the predetermined external signal may be, for example, a signal from a camera mounted inside the vehicle.

[0028] The sensor signal IF235 is used to input information acquired by sensors provided in the vehicle 20, such as an angular velocity sensor, a weight sensor, a temperature sensor, etc., to the CPU 210. For example, when a predetermined millimeter wave sensor or a camera is provided as a sensor in the vehicle 20, the sensor signal IF235 can convert an analog signal acquired by the sensor into a digital signal and provide it to the CPU 210.

[0029] The wide-area communication module 241 has a function of securing a wireless communication line with, for example, a wireless base station (not shown) provided by a mobile communication carrier, etc., and enabling wide-area wireless communication. The wide-area communication module 241 can communicate with the breathalyzer 100 via an antenna (not shown) and the network 40.

[0030] The non-volatile memory 242 is an electronic device such as a flash memory that can read data and rewrite the stored data by accessing the CPU 210. The non-volatile memory 242 is used to store data such as various parameters, constant data, programs, etc. used by the vehicle-mounted device 200.

[0031] The volatile memory 243 is a semiconductor memory device from which data can be read and written by access from the CPU 210. The volatile memory 243 is used to temporarily store various data handled by the CPU 210.

[0032] The SD card 244 is detachably connected to the vehicle-mounted device 200 using a predetermined card interface (not shown). The SD card 244 is used to store various data to be recorded by the vehicle-mounted device 200, such as operation data of the vehicle 20.

[0033] The SW input unit 245 includes switches that generate signals representing the operation states of a plurality of buttons for receiving input operations by a user such as the driver of the vehicle 20. For example, switch signals acquired by the SW input unit 245 include an ON / OFF signal of an ignition SW (not shown), an ON / OFF signal of a brake SW (not shown), an ON / OFF signal of a turn signal SW (not shown), etc. Signals of the operation states of each button (SW) are input from the SW input unit 245 to the CPU 210.

[0034] The LCD 246 is positioned on the front of the housing of the vehicle-mounted device 200 in a position that is easily visible to the driver, and is used under the control of the CPU 210 to display the operating status of the vehicle-mounted device 200 and to display information required for the user's input operations.

[0035] (Configuration of the alcohol testing device 100) 4 is a block diagram showing the configuration of the alcohol test apparatus 100 according to this embodiment. In this embodiment, the alcohol test apparatus 100 is configured by a general computer including a control unit 110, a storage unit 120, an input / output IF 130 (Interface), and a communication IF 140. The alcohol test apparatus 100 may be mounted as a function on, for example, a cloud server. The control unit 110 and the storage unit 120 will be described in detail later.

[0036] The input / output IF 130 is, for example, a component (interface) for a user to exchange data with the alcohol testing apparatus 100. The input / output IF 130 includes, for example, an input IF and an output IF (not shown).

[0037] The input IF in the input / output IF 130 has an interface function for inputting various information by the user, and information is input from outside the alcohol testing apparatus 100. Information is input to the input IF by the user via, for example, a keyboard, a mouse, a touch panel, a trackball, a voice recognition device, or the like, connected to the alcohol testing apparatus 100. The input IF can also input information as a data input terminal for inputting data from an external storage device (not shown) or the like.

[0038] The output IF in the input / output IF 130 can display user information (described later) on a display device (not shown) connected to the alcohol testing apparatus 100. The display device is, for example, a display device, a projector device, or the like.

[0039] The communication IF 140 is an interface for enabling mutual communication between the alcohol testing apparatus 100, the in-vehicle device 200 of the vehicle 20, and the administrator terminal 30 via the network 40.

[0040] (Functional configuration of the alcohol testing device 100) Fig. 5 is a block diagram showing the functional configuration of the alcohol test apparatus 100 according to this embodiment. As shown in Fig. 5, the control unit 110 of the alcohol test apparatus 100 includes, as functions, a user information acquisition unit 111, an alcohol concentration acquisition unit 112, an acquired information determination unit 113, a user information determination unit 114, an alcohol concentration determination unit 115, and a notification unit 116. Each function of the control unit 110 will be described later.

[0041] Furthermore, the control unit 110, for example, operates an operating system to control the entire alcohol testing apparatus 100. Furthermore, the control unit 110 operates based on a program stored in the storage unit 120 to execute each of the above-mentioned functions. Note that the program is not limited to being stored in the storage unit 120, and may be stored in, for example, a ROM (Read Only Memory) or the like (not shown) in the alcohol testing apparatus 100.

[0042] As shown in Fig. 5, the storage unit 120 stores information included in a user information DB 121 (DB: Database) as data. The number of storage units 120 that store each of these data may be one or more. For example, a single storage unit 120 may be configured to store the data in separate areas. Alternatively, the data may be distributed and stored in a plurality of storage devices that are installed in physically separate locations.

[0043] 5, information related to "user ID", "vehicle ID", "acquired information", "user information", and "alcohol concentration" is stored in the user information DB 121. The "user ID" is information for identifying the driver 32, and may be information included in the user information, such as authentication information or image data transmitted from the alcohol checker 300.

[0044] The "vehicle ID" is information for identifying the vehicle 20, and like the "user ID," may be included in user information such as authentication information and image data transmitted from the alcohol checker 300 and sent to the alcohol testing device 100.

[0045] The "acquired information" item stores the results of determination made by acquired information determination unit 113, which will be described later. The "user information" item stores the results of determination made by user information determination unit 114, which will be described later. The "alcohol concentration" item stores the results of determination made by alcohol concentration determination unit 115, which will be described later.

[0046] The user information acquisition unit 111 acquires, as user information, authentication information of the driver 32 acquired by the breathalyzer 300 and image data of the driver captured by the camera 320 mounted on the breathalyzer 300. In addition, the user information acquisition unit 111 stores the acquired user information in the user information DB 121.

[0047] The alcohol concentration acquisition unit 112 acquires the alcohol concentration information acquired by the alcohol checker 300 , and stores it in the user information DB 121 .

[0048] The acquired information determination unit 113 determines whether the image data and the alcohol concentration information are valid based on the authentication information. Specifically, when it is determined that the authentication information belongs to the driver 32, the acquired information determination unit 113 determines that the image data and the alcohol concentration information are valid.

[0049] The user information determination unit 114 determines the image data determined to be valid by the acquired information determination unit 113. Specifically, the user information determination unit 114 compares the image of the driver 32 included in this image data with image data registered in predetermined user information, and determines whether the user information, which is image data, is normal or not. In this embodiment, a general pattern matching technique is applied to the comparison of this image data.

[0050] When the user information determination unit 114 determines that the image data is normal, the alcohol concentration determination unit 115 determines the alcohol concentration contained in the breath of the driver based on the alcohol concentration information. Specifically, the alcohol concentration determination unit 115 determines whether the alcohol concentration in the breath of the driver 32 contained in the alcohol concentration information exceeds 0.15 mg / L. That is, when the alcohol concentration in the breath of the driver 32 is 0.15 mg / L or more, the alcohol concentration determination unit 115 determines that it is abnormal, and when the alcohol concentration is less than 0.15 mg / L, the alcohol concentration determination unit 115 determines that it is normal.

[0051] The threshold value of the alcohol concentration determined by the alcohol concentration determination unit 115 is not limited to 0.15 mg / L, but may be a threshold value lower than 0.15 mg / L, such as 0.1 mg / L.

[0052] The notification unit 116 notifies the in-vehicle device 200 of the vehicle 20 of the determination result of the alcohol concentration determination unit 115. Specifically, when the determination result of the alcohol concentration determination unit 115 is normal, the notification unit 116 sends a driving permission notification indicating that driving is permitted to the in-vehicle device 200. On the other hand, when the determination result of the alcohol concentration determination unit 115 is abnormal, the notification unit 116 sends a driving refusal notification indicating that driving is not permitted to the in-vehicle device 200.

[0053] Furthermore, in this embodiment, when the vehicle-mounted device 200 receives a driving permission notification, it sets the vehicle 20 to be capable of being driven, and causes the LCD 246 to display that driving is possible. On the other hand, when the vehicle-mounted device 200 receives a driving disallowance notification, it sets the vehicle 20 to be unable to be driven, and causes the LCD 246 to display that driving by the driver 32 is not possible.

[0054] (Outline of process flow of the alcohol testing device 100) Next, the flow of processing in the alcohol testing apparatus 100 will be shown using the flowchart shown in Fig. 7. The series of operations of the alcohol testing apparatus 100 shown in the flowchart in Fig. 7 starts when the alcohol testing apparatus 100 is started, and ends when the operation is completed. The processing in the flowchart shown in Fig. 1 also ends when the power is turned off or an interrupt occurs to end the processing. In addition, in the explanation of the flowchart below, the same contents as those described in the explanation of the alcohol testing system 10 and the alcohol testing apparatus 100 above will be omitted or simplified.

[0055] In step S701, the user information acquisition unit 111 acquires, as user information, the authentication information of the driver 32 acquired by the breathalyzer 300 and image data of the driver captured by the camera 320 mounted on the breathalyzer 300. The user information acquisition unit 111 also stores the acquired user information in the user information DB 121. After that, the process proceeds to step S702.

[0056] In step S702, the alcohol concentration acquisition unit 112 acquires the alcohol concentration information acquired by the alcohol checker 300, and stores it in the user information DB 121. After that, the process proceeds to step S703.

[0057] In step S703, the acquired information determination unit 113 determines whether the image data and alcohol concentration information are valid based on the authentication information. Specifically, when it is determined that the authentication information belongs to the driver 32, the acquired information determination unit 113 determines that the image data and alcohol concentration information are valid. In step S703, when the acquired information determination unit 113 determines that the acquired information, that is, the image data and alcohol concentration information, are valid (step S703: YES), the process proceeds to step S704. On the other hand, in step S703, when the acquired information determination unit 113 determines that the acquired information, that is, the image data and alcohol concentration information, are not valid (step S703: NO), the process proceeds to step S707.

[0058] In step S704, the user information determination unit 114 determines the image data determined to be valid by the acquired information determination unit 113. Specifically, the user information determination unit 114 compares the image of the driver 32 included in this image data with image data registered in predetermined user information, and determines whether the user information, which is image data, is normal or not. In this embodiment, a general pattern matching technique is applied to the comparison of this image data.

[0059] In step S704, if the user information determination unit 114 determines that the user information is normal (step S704: YES), the process proceeds to step S705. On the other hand, in step S704, if the user information determination unit 114 determines that the user information is not normal (step S704: NO), the process proceeds to step S707.

[0060] In step S705, when the user information determination unit 114 determines that the image data is normal, the alcohol concentration determination unit 115 determines the alcohol concentration contained in the breath of the driver based on the alcohol concentration information. Specifically, the alcohol concentration determination unit 115 determines whether the alcohol concentration in the breath of the driver 32 contained in the alcohol concentration information exceeds 0.15 mg / L. That is, when the alcohol concentration in the breath of the driver 32 is 0.15 mg / L or more, the alcohol concentration determination unit 115 determines that it is abnormal, and when the alcohol concentration is less than 0.15 mg / L, the alcohol concentration determination unit 115 determines that it is normal.

[0061] In step S705, if the alcohol concentration determination unit 115 determines that the alcohol concentration in the breath of the driver 32 is normal (step S705: YES), the process proceeds to step S706. On the other hand, in step S705, if the alcohol concentration determination unit 115 determines that the alcohol concentration in the breath of the driver 32 is not normal (step S705: NO), the process proceeds to step S707.

[0062] In step S706, the notification unit 116 transmits a driving permission notification indicating that driving is permitted to the vehicle-mounted device 200. Then, the process ends.

[0063] In step S707, the notification unit 116 transmits a driving non-permission notification indicating that driving is not permitted to the vehicle-mounted device 200. Then, the process ends.

[0064] As described above, the alcohol testing apparatus 100 according to this embodiment is an alcohol testing apparatus 100 that performs an alcohol test on the driver 32 who drives the vehicle 20 based on information acquired by the alcohol checker 300. The alcohol testing apparatus 100 includes a user information acquisition unit 111 that acquires, as user information, authentication information of the driver 32 acquired by the alcohol checker 300 and image data of the driver 32 captured by a camera mounted on the alcohol checker 300. The alcohol testing apparatus 100 also includes an alcohol concentration acquisition unit 112 that acquires alcohol concentration information acquired by the alcohol checker 300, and an acquired information determination unit 113 that determines whether the image data and the alcohol concentration information are valid based on the authentication information. The alcohol testing apparatus 100 also includes a user information determination unit 114 that determines image data determined to be valid by the acquired information determination unit 113. The alcohol testing device 100 also includes an alcohol concentration determination unit 115 that determines the alcohol concentration contained in the breath of the driver 32 based on the alcohol concentration information when the image data is determined to be normal by the user information determination unit 114. The alcohol testing device 100 also includes a notification unit 116 that notifies the in-vehicle device 200 of the vehicle 20 of the determination result of the alcohol concentration determination unit 115.

[0065] As a result, when measuring the alcohol concentration in an alcohol test, the alcohol testing device 100 acquires image data of the driver using a camera, and further measures the alcohol concentration and acquires the image data using a recording switch equipped with an authentication function. Therefore, it is difficult to commit fraud due to the difference in the acquired alcohol concentration measurement result and image data of the driver 32. Therefore, the alcohol testing device 100 according to this embodiment can more appropriately prevent fraud such as impersonation.

[0066] In addition, the recording switch 350 of the breathalyzer 300 may have a fingerprint authentication function for identifying the driver 32 based on the fingerprint of the driver 32. This enables the breathalyzer 100 to authenticate the driver 32 with higher accuracy.

[0067] Furthermore, the alcohol testing system 10 may further include an in-vehicle device 200 that enables driving of the vehicle 20 when the determination result notified by the notification unit 116 is normal. This enables the alcohol testing system 10 to set whether or not driving of the vehicle 20 is permitted according to the result of the alcohol test, making it possible to more appropriately prevent drunk driving.

[0068] (Other embodiments) Although the embodiments have been described in detail with reference to the drawings, the present embodiments are not limited to the contents described in the above embodiments. The components described above include those that a person skilled in the art can easily imagine and those that are substantially the same. Furthermore, the configurations described above can be appropriately combined. Various omissions, substitutions, or modifications of the configurations can be made without departing from the spirit of the embodiments.

[0069] In the above embodiment, the user information determination unit 114 is configured to determine whether the driver 32 is correct or not based on the image data. For example, the user information may be confirmed by the administrator 31 via the administrator terminal 30, and the result of the confirmation by the administrator 31 may be acquired by the user information determination unit 114 for determination.
