Hereinafter, the terminal device, the information processing system, the control method of the terminal device, and the control program of the terminal device according to the embodiment of the present invention will be described in detail with reference to the drawings.

First, the function of the information processing system will be described with reference to FIG. FIG. 1 is a block diagram showing an example of a software configuration of an information processing system according to an embodiment.

In FIG. 1, the information processing system 100 includes a measuring device 1, a terminal device 2, a face recognition device 3, and a management device 4. The measuring device 1 and the terminal device 2 are connected via wireless communication. The wireless communication connecting the measuring device 1 and the terminal device 2 is a communication using a communication method standardized in the short-range wireless communication standard. As a communication method in wireless communication, for example, Bluetooth (registered trademark) can be used. As a communication method in wireless communication, Bluetooth Low Energy (BLE) or the like, which is an extension of the Bluetooth specifications, may be used. In the following description, a case where a BLE communication method is used as wireless communication will be described as an example.

The terminal device 2 is a terminal used by a user, and is, for example, a mobile phone, a smartphone, a tablet PC, or the like. The terminal device 2 is connected to the network 9 by network communication such as mobile communication.

The terminal device 2, the face recognition device 3, and the management device 4 are communicably connected via the network 9.

The network 9 does not limit the communication method. The network 9 is, for example, the Internet. The network 9 may include wired communication or wireless communication as a part of the communication path. For example, the network 9 may include a mobile communication base station, a wireless LAN access point, and the like.

Note that FIG. 1 illustrates the configuration of the information processing system 100, and does not limit the configuration of the information processing system 100. For example, the information processing system 100 may include a plurality of any one of the measuring device 1, the terminal device 2, the face recognition device 3, and the management device 4.

The measuring device 1 has each functional unit of a communication control unit 11, a pressure measuring unit 12, a concentration measuring unit 13, a storage unit 14, and a device information display unit 15. The terminal device 2 includes a wireless communication unit 211, a data acquisition unit 212, a network communication unit 213, a data provision unit 214, a camera control unit 22, an authentication processing unit 23, a confirmation unit 24, a recording unit 25, and an incidental information acquisition unit 26. It has a functional part. Each of the above functional units in the information processing system 100 in the present embodiment will be described as being a functional module realized by a program (software).

The communication control unit 11 controls wireless communication with the terminal device 2. The communication control unit 11 outputs a radio signal for causing the terminal device 2 to recognize the existence of the measuring device 1. The communication control unit 11 outputs a wireless signal from the communication control unit 11 by unidirectional communication (broadcast type communication) at predetermined time intervals. When the wireless signal output from the communication control unit 11 is detected by the terminal device 2, the wireless communication unit 211 of the terminal device 2 transmits a response signal in response to the wireless signal. The response signal notifies the measuring device 1 that the wireless communication connection has been established. When the communication control unit 11 receives the response signal and is notified that the wireless communication has been established, the communication control unit 11 ends the wireless communication. When the wireless communication connection is disconnected, the communication control unit 11 may execute the wireless communication again to automatically restore the wireless communication with the terminal device 2. When the wireless communication is terminated, the communication control unit 11 may transmit a signal for disconnecting the connection to the terminal device 2.

The pressure measuring unit 12 measures the pressure of the exhaled air blown by the subject detected by the pressure sensor 121, and detects whether or not the pressure has reached a predetermined pressure. For example, if the subject intentionally reduces the amount of exhaled breath, the alcohol concentration contained in the exhaled breath may not be measured correctly. When the exhaled pressure measured by the pressure measuring unit 12 does not reach a predetermined pressure, it is possible to prevent an illegal measurement of the alcohol concentration by not measuring the alcohol concentration. When the pressure measuring unit 12 detects that the exhaled pressure has reached a predetermined pressure, the pressure measuring unit 12 may notify the subject by a chime sound or the like that the exhaled air is being blown correctly. Further, when the pressure measuring unit 12 detects that the exhaled pressure does not reach a predetermined pressure within a predetermined time, the exhaled air is insufficiently blown to the subject by an alarm sound or the like. May be notified.

The concentration measuring unit 13 measures the alcohol concentration contained in the exhaled breath detected by the concentration sensor 131 (hereinafter, may be referred to as “measurement result”). The measurement result may be a measured value (numerical value) of the alcohol concentration, a step evaluation according to the alcohol concentration (for example, A to D), a determination result of whether or not the concentration is equal to or higher than a predetermined concentration, and the like. The concentration sensor 131 selectively detects an alcohol component from various components contained in the exhaled breath. For the concentration sensor 131, for example, an electrochemical gas sensor can be used. When the measured value is higher than the preset alcohol concentration, the concentration measuring unit 13 may notify the subject by an alarm sound or the like.

The concentration measuring unit 13 measures the alcohol concentration when the pressure measuring unit 12 detects that the exhaled pressure has reached a predetermined pressure. For example, the concentration measuring unit 13 measures the alcohol concentration at the moment when the pressure reaches a predetermined pressure. The concentration measuring unit 13 may measure the alcohol concentration when a predetermined time elapses after the pressure reaches a predetermined pressure. Further, the concentration measuring unit 13 may measure the average value of the alcohol concentration at a time when the pressure is equal to or higher than a predetermined pressure.

The communication control unit 11 outputs the measurement result and the device information stored in the storage unit 14 to the terminal device 2. By acquiring the measurement result and the device information via the communication control unit 11, the terminal device 2 can recognize from which measuring device the acquired measurement result is output.

The communication control unit 11 outputs control information to the terminal device 2 when the pressure measurement unit 12 detects that the exhaled pressure has reached a predetermined pressure. The control information is information for controlling the shooting timing of the camera 221 in the terminal device 2. The timing for outputting the control information from the communication control unit 11 is after the exhaled pressure reaches a predetermined pressure in the pressure measuring unit 12. For example, the communication control unit 11 can output control information when the pressure reaches a predetermined pressure. Further, the communication control unit 11 may output control information when the pressure continues at a predetermined pressure or higher for a predetermined time. Further, the concentration measuring unit 13 may output control information when the measurement of the alcohol concentration in the concentration measuring unit 13 is completed.

The storage unit 14 stores device information for identifying the measuring device 1. The device information is information for specifying the measuring device 1, for example, a serial number or the like. The device information stored in the storage unit 14 may be protected so that the user (for example, the subject) of the measuring device 1 cannot easily rewrite the device information. The protection of the device information stored in the storage unit 14 can be performed, for example, by storing the device information in the secure area of the storage unit 14. Further, the protection of the device information stored in the storage unit 14 can be implemented by restricting the use of the program for rewriting the device information by a password or the like. By protecting the device information stored in the storage unit 14, it is possible to ensure identification from other measuring devices.

The storage unit 14 may store the setting of the transmission power of the wireless signal, the setting of whether or not to automatically execute the wireless communication when the power is turned on, and the like. The information stored in the storage unit 14 may be stored, for example, at the time of shipment from the factory of the measuring device 1.

The device information display unit 15 displays device information at a position where shooting can be performed from the camera 221 of the terminal device 2. The position that can be photographed from the camera 221 is a position that can be photographed from the camera 221 at least while the subject is blowing breath into the measuring device 1, and is, for example, the surface of the measuring device 1. The device information displayed by the device information display unit 15 may be, for example, visible light or infrared light radiated from the surface of the measuring device 1, and the device information may be expressed by blinking light.

Further, the device information display unit 15 may be a sticker on which a two-dimensional code including device information is printed. The sticker may be a sticker that makes it impossible to read the two-dimensional code once it is peeled off to prevent reattachment. In this embodiment, a case where the device information display unit 15 is a sticker of a two-dimensional code attached to the surface of the measuring device 1 will be described as an example.

The wireless communication unit 211 controls wireless communication with the measuring device 1. The wireless communication unit 211 detects the wireless signal output from the measuring device 1 and executes wireless communication to output a response signal in response to the detected wireless signal to the terminal device. When the wireless communication unit 211 detects the wireless signals of a plurality of measuring devices 1, it designates one measuring device 1 to be connected and outputs a response signal. That is, the wireless communication unit 211 establishes wireless communication with one measuring device 1. The wireless communication unit 211 enables reception of data from the measuring device 1 for which wireless communication has been established.

The data acquisition unit 212 acquires data from the measuring device 1 for which wireless communication has been established by the wireless communication unit 211. For example, the data acquisition unit 212 acquires the measurement result and the device information stored in the storage unit 14 from the measurement device 1. Further, the data acquisition unit 212 may acquire the control information output from the measuring device 1.

The network communication unit 213 controls communication with the face recognition device 3 and the management device 4 via the network 9. For example, the network communication unit 213 controls communication in mobile network communication, wireless LAN, or the like.

The data providing unit 214 provides the management device 4 communicably connected via the network 9 with the measurement results acquired by the data acquisition unit 212 and the facial photograph of the subject taken by the camera 221. ..

The camera control unit 22 controls the camera 221 based on the control information output from the measuring device 1 and acquired by the wireless communication unit 211 when a preset pressure is detected in the pressure measuring unit 12. As a result, the camera 221 can take a picture of the subject while breathing into the measuring device 1. For example, the camera control unit 22 operates the camera 221 to acquire a still image when the control information is acquired. Further, the camera control unit 22 may operate the camera 221 to acquire a moving image when the control information is acquired.

For example, it is assumed that the camera 221 is a front camera arranged on the same surface as the display unit of the terminal device 2. In this case, the subject can confirm the self-confidence image taken by the camera 221 on a display unit (not shown) of the terminal device 2. The subject adjusts the shooting position while checking the display unit of the terminal device 2 so that the device information displayed by the device information display unit 15 of the measuring device 1 and his / her face are photographed by the camera 221. can do. When the subject blows the exhaled air into the measuring device 1 in this state, the camera 221 can simultaneously capture the face of the subject and the device information when the subject is breathing. That is, the captured image captured by the camera 221 includes the face of the subject and the device information when the exhaled breath is being blown.

The camera control unit 22 may control the shooting with the camera 221 when a face is detected in the shot image. For example, the camera control unit 22 detects the face of the subject from the captured images captured by the camera 221 and records the captured image as a still image when the face is detected. Further, the camera control unit 22 may start recording the captured image as a moving image when a face is detected.

Further, the camera control unit 22 may perform image processing on the captured image and record it. For example, the camera control unit 22 may trim the captured image based on the detected face position. The captured image recorded by the camera control unit 22 may include an image processed image.

The authentication processing unit 23 transmits the captured image captured by the camera 221 to the face authentication device 3. The face recognition device 3 is a device that authenticates the person's identity based on a face photograph. The face recognition device 3 is, for example, a service server that provides a Web service of the face recognition service. For example, a face photograph of a subject is registered in advance in the face recognition device 3. A plurality of face photographs of the subject taken from different angles may be registered in the face recognition device 3. The face recognition device 3 extracts the feature amounts of the pre-registered face photograph and the captured image transmitted from the authentication processing unit 23, and compares the feature amounts of each. In the face recognition device 3, whether or not the subject included in the photographed image transmitted from the authentication processing unit 23 is the person of the pre-registered face photograph, depending on whether or not the features are close to each other (authentication OK). Alternatively, it is possible to authenticate whether the person is another person (authentication NG). The face recognition device 3 may transmit the authentication result to the authentication processing unit 23 and the management device 4.

Further, the authentication processing unit 23 may acquire the authentication result transmitted from the face recognition device 3. The authentication processing unit 23 may display the acquired authentication result on a display device (not shown) of the terminal device 2. When the acquired authentication result is NG, the authentication processing unit 23 may notify the authentication result from a display unit or a speaker (not shown) of the terminal device 2.

Further, the authentication processing unit 23 may transmit the captured image processed by the camera control unit 22 to the face recognition device 3. For example, the authentication processing unit 23 may transmit the captured image in which the subject's face is detected by the camera control unit 22 and trimmed to the face authentication device 3. The authentication processing unit 23 can reduce the transmission capacity by transmitting the trimmed captured image.

The confirmation unit 24 confirms that the device information acquired from the measuring device 1 in the wireless communication unit 211 matches the device information displayed in the device information display unit 15 captured by the camera 221. For example, the confirmation unit 24 decodes the two-dimensional code included in the captured image and acquires the device information included in the two-dimensional code. The confirmation unit 24 confirms that the device information acquired together with the alcohol concentration measurement result matches the device information captured by the camera 221 so that the alcohol concentration measurement result is measured by the camera 221. It can be confirmed that the result is measured by the device 1.

By confirming the match of the device information in the confirmation unit 24, for example, a collaborator who is not drinking alcohol blows the exhaled breath to the measuring device 1 near the subject who blows the exhaled air to the device different from the measuring device 1. This makes it possible to prevent fraud that slips through the alcohol test.

The recording unit 25 records the measurement result of the alcohol concentration measured when the pressure measuring unit 12 detects a preset pressure when the confirmation unit 24 confirms that the device information matches. By recording the measurement result when the confirmation unit 24 confirms that the device information matches, the recording unit 25 can prevent the measurement result measured by another measuring device from being recorded. It is possible to prevent fraud in alcohol concentration measurement.

Further, the recording unit 25 may record the captured image captured by the camera 221 together with the measurement result. By recording the captured image together with the measurement result, it becomes possible to easily grasp the correspondence between the subject and the measurement result when confirming the measurement result on the terminal device 2.

The incidental information acquisition unit 26 acquires incidental information that can be acquired by the terminal device 2. The incidental information that can be acquired by the terminal device 2 is, for example, the position information (geotag) of the terminal device 2 at the time of shooting by the camera 221, the time, the shooting conditions of the camera 221 and the like. The recording unit 25 may record the incidental information acquired by the incidental information acquisition unit 26 together with the captured image or the measurement result. The data providing unit 214 may transmit the incidental information acquired by the incidental information acquisition unit 26 to the management device 4.

For example, the position information acquired by the incidental information acquisition unit 26 can be used as information for certifying the location where the alcohol concentration measurement was performed. In the information processing system 100, since the subject can carry the measuring device 1 and the terminal device 2, the alcohol concentration can be measured at any place. For example, suppose that a car driven by a subject is parked in a predetermined parking lot, and alcohol concentration measurement is obligatory immediately before driving. By comparing the position information of the parking lot known in advance with the position information at the time of shooting acquired by the incidental information acquisition unit 26, it can be proved that the alcohol concentration measurement was performed at an appropriate place. Similarly, the time information acquired by the incidental information acquisition unit 26 makes it possible to prove the time when the concentration was measured.

The management device 4 is a device that manages the alcohol test performed by the subject. The management device 4 records the measurement result acquired from the data providing unit 214 and the photographed image of the subject. For example, the management device 4 can create an examination history for each subject by recording the measurement result and the photographed image of the subject for each subject. Further, the management device 4 can manage the working state of the subject by recording the working record, the measurement result and the photographed image for each subject. For example, when the subject is a truck driver, the driver's fatigue state, etc. can be managed by recording the working hours, mileage, loading status, etc. together with the measurement results and captured images as work records. Is possible.

While visually recognizing the display unit 222 of the terminal device 2, the subject 5 adjusts the shooting position and direction of the terminal device 2 so that his / her face and the two-dimensional code 162 are displayed on the display unit 222. Subject 5 blows exhaled air into the straw 166 and measures the alcohol concentration while confirming that his / her face and the two-dimensional code 162 are displayed on the display unit 222. When the pressure measuring unit 12 of FIG. 1 detects a preset pressure, the captured image of the camera 221 is recorded and displayed on the display unit 222. The measurement result measured by the measuring device 1 is acquired by the terminal device 2 by wireless communication together with the device information stored in the storage unit 14. The display unit 222 may display the acquired measurement result and the captured image together.

Next, the operation of the measuring device 1 will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the operation of the measuring device according to the embodiment. Although the execution subject of the operation in the flowchart shown below will be described as being the measuring device 1, each operation can be executed in each functional unit of the above-mentioned measuring device 1.

In FIG. 4, the measuring device 1 determines whether or not the power button has been turned on (step S11). When it is determined that the power button is not turned on (step S11: NO), the measuring device 1 repeats the process of step S11 and waits for the power button to be turned on.

When it is determined that the power button is turned on (step S11: YES), the measuring device 1 starts outputting the radio signal (step S12).

After executing the process of step S12, the measuring device 1 determines whether or not the response signal has been received (step S13). When it is determined that the response signal has not been received (step S13: NO), the measuring device 1 determines whether or not the power button has been turned off (step S14). When it is determined that the power button is not turned off (step S14: NO), the measuring device 1 repeats the processes of steps S13 to S14 and waits for the power button to be operated.

When it is determined that the response signal has been received (step S13: YES), the measuring device 1 activates the concentration sensor (step S15). In this embodiment, the usage conditions of the concentration sensor are limited after the wireless communication is established, but the concentration sensor may be activated by turning on the power button.

After executing the process of step S15, the measuring device 1 determines whether or not the exhaled pressure has reached a preset pressure (step S16). When it is determined that the exhaled pressure has not reached the preset pressure (step S16: NO), the measuring device 1 skips the processes of steps S17 to S20, and the exhaled pressure is the preset pressure. Wait to reach. On the other hand, when it is determined that the exhaled pressure has reached a preset pressure (step S16: YES), the measuring device 1 starts measuring the alcohol concentration (step S17).

After executing the process of step S17, the measuring device 1 determines whether or not the measurement is completed (step S18). Whether or not the measurement is completed can be determined, for example, by whether or not the exhaled pressure continues for a predetermined time or longer. When it is determined that the measurement has not been completed (step S18: NO), the measuring device 1 repeats the processes of steps S16 to S18, and measures the exhaled pressure in a state where the pressure is maintained at or higher than the preset pressure. Wait for it to finish.

On the other hand, when it is determined that the measurement is completed (step S18: YES), the measuring device 1 outputs the measurement result to the terminal device 2 (step S19) and outputs the control information (step S20).

After executing the process of step S20, or when it is determined that the exhaled pressure has not reached the preset pressure (step S16: NO), the measuring device 1 determines whether or not to end the measurement. (Step S21). Whether or not to end the measurement can be determined, for example, when the exhaled pressure does not reach a predetermined pressure for a predetermined time or more, or when it is determined that all the measurements in the measuring device 1 have been completed. When it is determined that the measurement is not completed (step S21: NO), the measuring device 1 repeats the processes of steps S16 to S20.

On the other hand, when it is determined that the measurement is finished (step S21: YES), or when it is determined that the power button is turned off in the process of step S14 (step S14: NO), the measuring device 1 ends the output of the wireless signal. (Step S22). After executing the process of step S22, the measuring device 1 ends the operation of the flowchart shown in the figure.

Next, the operation of the terminal device 2 will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the operation of the terminal device 2 in the embodiment. The operation of the flowchart described in FIG. 5 is assumed to be started by invoking an application program (may be abbreviated as "application") that controls the terminal device 2 installed in the terminal device 2. Although the execution subject of the operation in the flowchart shown below will be described as being the terminal device 2, each operation can be executed in each functional unit of the terminal device 2 described above.

In FIG. 5, the terminal device 2 activates the camera 221 (step S31). By activating the camera 221, the captured image is displayed on the display unit 222.

After executing the process of step S31, the terminal device 2 determines whether or not the radio signal output from the measuring device 1 is detected (step S32). If it is determined that the wireless signal has not been detected (step S32: NO), the terminal device 2 repeats the process of step S32 and waits for the wireless signal to be detected.

On the other hand, when it is determined that the wireless signal has been detected (step S32: YES), the terminal device 2 outputs a response signal in response to the wireless signal to the measuring device 1 (step S33).

After executing the process of step S33, the terminal device 2 determines whether or not the measurement result has been acquired from the measuring device 1 (step S34). When it is determined that the measurement result has not been acquired (step S34: NO), the terminal device 2 repeats the process of step S34 and waits for the acquisition of the measurement result. On the other hand, when it is determined that the measurement result has been acquired (step S34: YES), the terminal device 2 temporarily stores the measurement result (step S35). For example, the recording unit 25 can temporarily store the measurement result.

After executing the process of step S35, it is determined whether or not the control information has been acquired from the measuring device 1 (step S36). When it is determined that the control information has not been acquired (step S36: N0), the terminal device 2 repeats the process of step S36 and waits for the acquisition of the control information. On the other hand, when it is determined that the control information has been acquired (step S36: YES), the terminal device 2 acquires the captured image from the camera 221 (step S37) and records the captured image (step S38).

After executing the process of step S38, the terminal device 2 executes image processing on the captured image (step S39). The image processing is, for example, trimming of a captured image, color correction, brightness correction, resolution correction, and the like. After executing the process of step S39, the terminal device 2 transmits the image data of the captured image to the face authentication device 3 (step S40).

After executing the process of step S40, the terminal device 2 determines whether or not the device information matches in the confirmation of the confirmation unit 24 (step S41). When it is determined that the device information does not match (step S41: NO), the terminal device 2 notifies the confirmation result (mismatch of device information, etc.). The notification of the confirmation result can be executed, for example, by displaying the confirmation result on the display unit 222.

On the other hand, when it is determined that the device information matches (step S41: YES), the terminal device 2 determines whether or not the personal authentication is OK (step S43). Whether or not the personal authentication is OK can be determined, for example, by acquiring the authentication result from the face recognition device 3. When it is determined that the personal authentication is not OK (step S43: NO), the terminal device 2 notifies the authentication result (identification NG). The notification of the authentication result can be executed, for example, by displaying the confirmation result on the display unit 222.

On the other hand, when it is determined that the personal authentication is OK (step S43: YES), the terminal device 2 records the measurement result (step S45) and provides the recorded measurement result to the management device 4 (step S46). .. After executing the process of step S42, the process of step S44, or the process of step S46, the terminal device 2 ends the operation shown in the flowchart.

Next, other operations of the terminal device 2 will be described with reference to FIG. FIG. 6 is a flowchart showing another example of the operation of the terminal device 2 in the embodiment.

In FIG. 6, when the application is started, the terminal device 2 displays an input screen for inputting the roll call category and instructs the subject to input the roll call category (step S51). The roll call classification is a classification of roll call work in business, and is classified according to the timing of going to work, during work, or leaving work, for example. The roll call category may include, for example, a "work roll call" performed at work, an "intermediate roll call" performed during work, or a "leaving roll call" performed at the time of leaving work. The terminal device 2 may display a selection button for selecting one of the roll call categories so that the subject can operate the selection button.

After executing the process of step S51, the terminal device 2 determines whether or not the selection of the roll call category is completed (step S52). When it is determined that the selection of the roll call category is not completed (step S52: NO), the terminal device 2 repeats the process of step S52 and waits for the selection of the roll call category to be completed.

On the other hand, when it is determined that the selection of the roll call category is completed (step S52: YES), the terminal device 2 activates the camera 221 and starts shooting (step S53). By activating the camera 221, the captured image is displayed on the display unit 222.

After executing the process of step S53, the terminal device 2 determines whether or not the device authentication is successful (step S54). Whether or not the device authentication is successful can be executed in the same manner as the processes of steps S36 to S41 described with reference to FIG. That is, the terminal device 2 can determine that the device authentication has been successful by acquiring the device information from the measuring device 1 and determining whether or not it matches the captured device information. If it is determined that the device authentication is not successful (step S54: NO), the terminal device 2 returns to the process of step S51 and waits for the roll call classification selection to be completed again.

On the other hand, when it is determined that the device authentication is successful (step S54: YES), the terminal device 2 displays a screen instructing the subject to turn on the power of the measuring device 1 (step S55).

After executing the process of step S55, the terminal device 2 connects the wireless communication with the measuring device 1 (step S56). The wireless communication connection can be executed in the same manner as the processes of steps S32 to S33 described with reference to FIG.

After executing the process of step S56, the terminal device 2 determines whether or not the personal authentication is successful (step S57). The determination of whether or not the personal authentication is successful can be executed in the same manner as the processes of steps S37 to S40 and step S43 described in FIG. The terminal device 2 may display the name and the like of the authenticated subject, and when the subject confirms it, it may be determined that the identity authentication is successful. When it is determined that the personal authentication is not successful (step S57: NO), the terminal device 2 repeats the process of step S57 and waits for the personal authentication to succeed. The process of personal authentication in the process of step S57 may be terminated by, for example, a predetermined number of failures, and the operation shown in the flowchart may be terminated. The failure of the personal authentication may be notified to the management device 4.

On the other hand, when it is determined that the personal authentication is successful (step S57: YES), the terminal device 2 displays the self-diagnosis input screen so that the subject can input the self-diagnosis result. The self-diagnosis is a self-state that the subject declares himself / herself, and includes, for example, the presence / absence of injury, the presence / absence of drowsiness, the physical condition, the presence / absence of taking medicine, the presence / absence of drinking, and the like. If the result of the self-diagnosis is bad even for one of the declaration items, the terminal device 2 may notify the management device 4 of the diagnosis result and end the operation shown in the flowchart.

After executing the process of step S58, the terminal device 2 displays a screen instructing the start of the measurement in the measuring device 1 and prompts the subject to start the measurement (step S59).

After executing the process of step S59, the terminal device 2 activates the camera 221 to start shooting, and determines whether or not the personal authentication is successful based on the captured personal image (step S60). .. By performing personal authentication before starting the measurement in the measuring device 1, it is possible to prevent spoofing in which the subjects are replaced. When it is determined that the personal authentication is not successful (step S60: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication and ends the operation shown in the flowchart.

On the other hand, when it is determined that the personal authentication is successful (step S60: YES), the terminal device 2 determines whether or not the measurement has been started (step S61). Whether or not the measurement has been started can be determined, for example, by whether or not the pressure measured by the pressure measuring unit 12 has reached a preset pressure. When the pressure measured by the pressure measuring unit 12 is preset, it can be determined that the measurement by the measuring device 1 is in the middle of measurement (during measurement). When it is determined that the measurement has not been started (step S61: NO), the terminal device 2 repeats the process of step S61 and waits for the measurement to be started.

On the other hand, when it is determined that the measurement has been started (step S61: YES), the terminal device 2 determines whether or not the personal authentication is successful (step S62). By performing personal authentication during the measurement in the measuring device 1, it is possible to prevent the subject from being spoofed during the measurement. When it is determined that the personal authentication is not successful (step S62: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication and ends the operation shown in the flowchart.

On the other hand, when it is determined that the personal authentication is successful (step S62: YES), the terminal device 2 determines whether or not the measurement is completed (step S63). Whether or not the measurement is completed can be determined, for example, by whether or not the measurement result is obtained from the measuring device 1. If it is determined that the measurement has not been completed (step S63: NO), the terminal device 2 repeats the process of step S63 and waits for the measurement to be completed.

On the other hand, when it is determined that the measurement is completed (step S63: YES), the terminal device 2 determines whether or not the personal authentication is successful (step S64). By performing personal authentication at the end of measurement in the measuring device 1, it is possible to further prevent spoofing in which the subject is replaced during the measurement. When it is determined that the personal authentication is not successful (step S64: NO), the terminal device 2 notifies the management device 4 of the failure of the personal authentication and ends the operation shown in the flowchart.

In the operation shown in FIG. 6, the effect of preventing spoofing can be enhanced by performing personal authentication a plurality of times. The timing and number of times of personal authentication may be arbitrarily selected. The timing and number of times of personal authentication may differ depending on the application in which the terminal device is used or the request of the user, and by allowing the timing and number of times of personal authentication to be set arbitrarily, flexibility in personal authentication is achieved. Operation becomes possible. For example, it may be possible to set so that only one of the personal authentications in step S57, step S60, step S62 or step S64 is performed. Further, it may be possible to set to perform any two of the personal authentication in step S57, step S60, step S62 or step S64.

Further, the personal authentication in steps S60, S62, and S64 may be performed without the subject noticing. Once the subject knows when to authenticate himself, a method of avoiding authentication may be considered. By executing the personal authentication at a timing that the subject does not notice, it is possible to prevent intentional authentication avoidance.

On the other hand, when it is determined that the personal authentication is successful (step S64: YES), the terminal device 2 records the measurement result (step S65), transmits the measurement result (step S66), and ends the operation shown in the flowchart. .. The process of recording the measurement result in step S65 can be executed in the same process as in step S45. Further, the measurement result transmission process in step S66 can be executed in the same process as in step S46.

The illustrated flowchart shows an example of the operation in the present embodiment, and does not limit the operation in the measuring device 1 or the terminal device 2.

For example, in FIG. 6, when it is determined that the device authentication is not successful (step S54: NO), the operation of returning to the process of step S51 and waiting for the selection of the roll call category to be completed again is illustrated. However, if it is determined that the device authentication is not successful (step S54: NO), a screen for waiting for a certain period of time (for example, 2 minutes) to elapse and then interrupting the system is displayed, and the OK button is pressed. After being pressed, the process may return to the process of step S51.

Further, when it is determined that the personal authentication is not successful (step S57: NO), the operation of repeating the process of step S57 and waiting for the personal authentication to succeed is exemplified. However, if it is determined that the personal authentication is not successful (step S57: NO), a screen for waiting for a certain period of time to elapse, then a screen for interrupting the system is displayed, and after the OK button is pressed, the step is performed. You may return to the process of S51.
