JP 2014-006675 A

  In the conventional alcohol measurement system, when there is a possibility that the alcohol concentration in the exhalation of the subject is high, when the subject's manager is absent at the place where the alcohol measurement is performed, the exhalation of the subject In order to make the alcohol concentration appear low, various fraudulent acts may be performed in which a gas other than the exhaled breath of the measurement subject is blown into the alcohol measuring device.

  For example, in a conventional alcohol measurement system, an alcoholic measure for a person being measured is simply performed by an improper act that causes the person who is the person to be measured to execute the exhalation of the person to be measured. A fraudulent act of blowing into an alcohol meter may be performed. However, in the conventional alcohol measurement system, since a moving image of a person who is breathing into the alcohol measuring device is left, such an illegal act can be specified from the moving image by the administrator.

  Further, in the conventional alcohol measurement system, a tube in which exhaled breath can be infused from a person who is immedi- ate of the subject even if the subject is holding a breath inhalation portion in which exhaled breath is blown by the subject. By improperly remodeling the alcohol measuring instrument, such as improperly attached to the measuring instrument, the video of the person being measured holding the exhalation breathing part remains, and exhalation from a surrogate person outside the camera shooting range There is a possibility that fraudulent acts will be executed. However, in the conventional alcohol measurement system, if an unauthorized modification to the alcohol measuring device or a video taken by a surrogate is taken by the camera, such an illegal act is identified by the administrator from the video. Is possible. In such fraudulent acts, during the measurement of alcohol, there may be cases where the person who is impersonated pays enough attention to prevent unauthorized modification of the alcohol measuring device or the person impersonating the camera. Many. However, since the attention of the surrogate is often lower before and after the alcohol measurement than when the alcohol measurement is being performed, unauthorized modification of the alcohol measuring instrument or the surrogate by the camera The possibility of being photographed increases.

  Also, in the conventional alcohol measurement system, by providing a dummy exhalation blowing part, a video of the measurement person holding the dummy exhalation blowing part remains, and the substitution of the measurement person outside the camera shooting range is possible. There is a possibility that a fraudulent act in which exhalation is blown into a real exhalation blowing unit from a person who is a person will be executed. However, in the conventional alcohol measurement system, if the exhalation breathing part that the person being measured gives is a dummy, or if it appears in a video taken by a surrogate person with a camera, such an illegal act Can be identified from the video by the administrator. In addition, in such fraudulent acts, the breath inhalation part that the person being measured falsifies is a dummy at the time before and after the alcohol measurement, similar to the fraudulent acts in which the alcohol measuring instrument is tampered with. There is an increased possibility that the camera will show a part that shows or a substitute person.

  However, in the conventional alcohol measurement system, there is a video from the start to the end of the call that starts basically regardless of the start time of alcohol measurement and ends basically regardless of the end time of alcohol measurement. Since it is stored, it is not easy for the administrator to specify a location highly relevant to the measurement operation executed by the alcohol measuring device for alcohol measurement. Therefore, in the conventional alcohol measurement system, there is a problem that it is not easy to identify fraudulent acts for alcohol measurement from moving images.

  Accordingly, an object of the present invention is to provide an alcohol measurement system and an alcohol measurement moving image storage program that can make it easier to identify an illegal act against alcohol measurement from a moving image.

  The alcohol measurement system of the present invention includes an alcohol measuring device that performs alcohol measurement, which is a measurement of alcohol concentration in exhaled breath that is blown by the measured person, and the measured device that is inhaling the breath into the alcohol measuring device. A camera arranged at a position where a person can be photographed, and a moving image photographed by the camera and associated with a measurement operation performed by the alcohol measuring device for the alcohol measurement A moving image storage means for storing, wherein the measurement related moving image includes a time of the measurement operation from a start time to an end time, and the measurement related moving image has a start time of the start of the measurement operation. At least one of the specific time before the time and the end time being a specific time after the end time of the measurement operation. And it satisfies the.

  With this configuration, the alcohol measurement system of the present invention has a measurement operation time, a specific time before the start time of the measurement operation, and a specific time after the end time of the measurement operation. Since the measurement-related moving image of a series of time is stored, it is possible to make it easier to identify fraudulent acts for alcohol measurement from the moving image.

  In the alcohol measurement system of the present invention, the time from the start time of the measurement related video to the start time of the measurement operation is a fixed time, and from the end time of the measurement operation to the end time of the measurement related video This time may satisfy at least one of the certain time.

  With this configuration, the alcohol measurement system according to the present invention measures the time from the start time of the measurement-related video to the start time of the measurement operation and the time from the end time of the measurement operation to the end time of the measurement-related video. Compared to the configuration that changes from video to video, the time length uniformity of measurement related videos can be improved, so the efficiency of checking the measurement related videos to detect fraudulent acts on alcohol measurement is improved. Can be improved.

  The alcohol measurement system of the present invention is constant among the time from the start time of the measurement-related moving image to the start time of the measurement operation and the time from the end time of the measurement operation to the end time of the measurement-related moving image. You may provide the time setting means which can set at least 1 which is time.

  With this configuration, the alcohol measurement system of the present invention can change how much time before or after the measurement operation time is stored in the measurement-related video by a person such as the measurement subject administrator. Therefore, it is possible to effectively give a mental pressure that a person who wants to perform an illegal act on alcohol measurement may be performing shooting for a measurement-related moving image. Therefore, the alcohol measurement system of the present invention can suppress the occurrence of fraudulent acts with respect to alcohol measurement.

  The alcohol measurement system of the present invention is at least one of a time from a start time of the measurement-related moving image to a start time of the measurement operation and a time from the end time of the measurement operation to the end time of the measurement-related moving image. It is possible to provide time determining means for determining the changeable for each measurement-related moving image.

  With this configuration, the alcohol measurement system of the present invention makes it difficult for a person who wants to execute an illegal act on alcohol measurement to grasp at least one of the start time and the end time of the measurement-related video. Therefore, it is difficult to carry out fraudulent acts on alcohol measurement. Therefore, the alcohol measurement system of the present invention can suppress the occurrence of fraudulent acts with respect to alcohol measurement.

  The alcohol measurement system of the present invention may not notify that the current time is during the shooting time of the measurement-related moving image.

  With this configuration, the alcohol measurement system of the present invention can give a mental pressure to a person who wants to perform an illegal act on alcohol measurement, that may be in the process of shooting for a measurement-related video. It is difficult to carry out fraudulent acts on alcohol measurement. Therefore, the alcohol measurement system of the present invention can suppress the occurrence of fraudulent acts with respect to alcohol measurement.

  In the alcohol measurement system of the present invention, the moving image storage means may store the measurement-related moving image in association with the result of the alcohol measurement when the alcohol measurement is normally completed in the measurement operation.

  With this configuration, the alcohol measurement system of the present invention can select a measurement-related moving image according to the result of alcohol measurement. By selecting a measurement-related video below the concentration level, it is easy to find from the measurement-related video that “an alcohol concentration is lower than the actual alcohol concentration in the exhalation of the subject due to fraud in alcohol measurement”. Can be made.

  In the alcohol measurement system of the present invention, the moving image storage means may store the measurement-related moving image even when the measurement operation is terminated halfway.

  When the measurement operation is terminated halfway, it is highly possible that an illegal act for alcohol measurement has been performed, compared to the case where the measurement operation is completed normally. Since the alcohol measurement system of the present invention stores a measurement-related moving image when the measurement operation is terminated halfway, it is possible to improve the possibility that an illegal act against alcohol measurement is detected by the measurement-related moving image.

  The alcohol measurement system of the present invention includes list display means for displaying a list of the measurement-related moving pictures stored by the moving picture storage means, and the list display means has a time for the measurement operation equal to or longer than a specific time. It may be displayed in the list separately whether or not it is the measurement-related moving image.

  When the measurement operation time is long, there is a high possibility that fraudulent acts on alcohol measurement are being performed compared to when the measurement operation time is short. The alcohol measurement system according to the present invention is capable of measuring a measurement-related movie in which the measurement operation time is longer than a specific time, that is, a measurement-related movie in which the measurement operation time is long. Since videos are displayed in a list separately from measurement-related videos with a short measurement operation time, measurement-related videos with a long measurement operation time can be easily selected from many measurement-related videos. it can. Therefore, the alcohol measurement system of the present invention can easily find an illegal act against alcohol measurement by a measurement-related moving image.

  The alcohol measurement system of the present invention includes list display means for displaying a list of the measurement related videos stored by the video storage means, and the list display means displays the length of the measurement related videos in the list. You may display.

  When the measurement operation time is long, there is a high possibility that fraudulent acts on alcohol measurement are being performed compared to when the measurement operation time is short. Since the alcohol measurement system of the present invention displays the measurement operation time in a list, a measurement-related moving image having a long measurement operation time can be easily selected from a large number of measurement-related moving images. Therefore, the alcohol measurement system of the present invention can easily find an illegal act against alcohol measurement by a measurement-related moving image.

  The alcohol measurement system of the present invention may include a microphone that acquires sounds around the alcohol measuring device, and the moving image storage means may include the sound acquired by the microphone in the measurement-related moving image.

  With this configuration, the alcohol measurement system of the present invention can confirm whether or not an illegal act for alcohol measurement has been executed by the sound included in the measurement-related video. Can be made easier.

  The alcohol measurement moving image storage program of the present invention is a moving image taken by a camera of a computer connected to an alcohol measuring device that performs alcohol measurement, which is measurement of alcohol concentration in exhaled breath blown by a subject. , Functioning as a moving image storing means for storing a measurement related moving image associated with a measuring operation executed by the alcohol measuring device for measuring the alcohol, and the camera blowing the breath into the alcohol measuring device The measurement related moving image includes a time for the measurement operation from a start time to an end time, and the measurement related moving image includes a start time. A specific time before the start time of the measurement operation and an end time from the end time of the measurement operation. And satisfies at least one of the possible is after a constant time.

  With this configuration, the computer that executes the alcohol measurement movie storage program of the present invention can perform the measurement operation time, the specific time before the start time of the measurement operation, and the specific time after the end time of the measurement operation. Since a measurement-related moving image of a series of times consisting of at least one of these times is stored, it is possible to make it easier than ever to identify an illegal act for alcohol measurement from a moving image.

The alcohol measurement system 10 allows the administrator to confirm whether or not fraudulent activity has been performed in the alcohol measurement even when the administrator of the person being measured is absent at the alcohol measurement execution location. System.

  FIG. 2 is a block diagram of the alcohol measuring device 20.

  As shown in FIG. 1 and FIG. 2, the alcohol measuring device 20 includes an operation unit 21 that is an operation device such as a keyboard, a display unit 22 that is a display device, a speaker 23, and exhaled breath that is inhaled by the measurement subject. A sensor unit 24 to which a mouthpiece 24a as a blowing unit can be attached and detached, a communication unit 25 that is a communication device that communicates with a computer 40, and a control unit 26 that controls the alcohol measuring instrument 20 as a whole. The alcohol measuring device 20 is a device that performs measurement of the alcohol concentration in exhaled breath blown into the mouthpiece 24a.

  The display unit 22 includes a plurality of lamps 22a for notifying the measurement subject of various types of information such as information indicating the current state of the alcohol measuring device 20 and information indicating an operation instruction for the alcohol measuring device 20, and alcohol measurement. And a display 22b for notifying the measurement subject of various types of information such as information indicating the current state of the container 20, information indicating an operation instruction to the alcohol measuring instrument 20, and information indicating the measured alcohol concentration. . For example, the display 22b is an 8-digit 7-segment display.

  The sensor unit 24 can output an alcohol concentration signal corresponding to the alcohol concentration in the expired air blown through the mouthpiece 24 a to the control unit 26. Further, the sensor unit 24 can output an expiratory pressure signal corresponding to the expiratory pressure blown through the mouthpiece 24 a to the control unit 26.

  The control unit 26 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) storing a program and various data, and a RAM (Random Access Memory) used as a work area of the CPU. Yes. The CPU executes a program stored in the ROM.

  FIG. 3A is an external perspective view of the alcohol measuring device 20 in a state in which the person under measurement 90 blows into the mouthpiece 24a. FIG. 3B is a diagram illustrating an example of an image photographed by the Web camera 31 when the measurement subject 90 is in the state of breathing into the mouthpiece 24a.

  As shown in FIGS. 1 and 3, the Web camera 31 is arranged at a position where the measurement subject 90 in a state where exhalation is blown into the mouthpiece 24 a can be photographed.

  The microphone 32 is a device that acquires sound around the alcohol measuring device 20.

  FIG. 4 is a block diagram of the computer 40.

  As shown in FIGS. 1 and 4, the computer 40 includes an operation unit 41 that is an operation device such as a mouse and a keyboard, a display unit 42 that is a display device such as an LCD (Liquid Crystal Display), a speaker 43, and alcohol. A communication unit 44 that is a communication device that communicates with the measuring device 20, the Web camera 31, and the microphone 32, and a storage unit 45 that is a non-volatile storage device such as an HDD (Hard Disk Drive) that stores various types of information or a semiconductor memory. And a control unit 46 that controls the entire computer 40.

  The storage unit 45 is a moving image photographed by the Web camera 31 and is related to measurement associated with a series of operations (hereinafter referred to as “measurement operations”) executed by the alcohol measuring device 20 for alcohol measurement. An alcohol measurement moving image storage program 45a for storing moving images is stored.

  The storage unit 45 stores a user information table 45b that shows user information for each user.

  FIG. 5 is a diagram illustrating an example of the user information table 45b.

  The user information table 45b shown in FIG. 5 includes the user ID and the user name. For example, in the example shown in FIG. 5, the name of the user with ID “1” is “Taro Tokai”.

  As illustrated in FIG. 4, the storage unit 45 can store a measurement-related moving image 45 c for each measurement operation.

  FIG. 6 is a diagram illustrating a configuration of the measurement related moving image 45c.

  As shown in FIG. 6, the measurement-related moving image 45c includes a measurement operation time from the start time to the end time. Here, for the measurement operation, for example, the alcohol measurement device 20 can perform the alcohol measurement on the measurement subject 90 by inputting the ID registered in the user information table 45 b to the operation unit 21. It starts at the time. The measurement operation is terminated when the alcohol measurement for the measurement subject 90 is normally completed in the alcohol measuring device 20, for example, when the measured alcohol concentration is displayed on the display 22b. Further, the measurement operation may be terminated halfway without being displayed on the display 22b due to an instruction from the operation unit 21 or a timeout.

  The measurement-related moving image 45c includes a moving image of a certain time (hereinafter referred to as “a certain time before the measuring operation”) as a specific time before the measuring operation time. That is, the start time of the measurement-related moving image 45c is a certain time before the measurement operation before the measurement operation start time.

  The measurement-related moving image 45c includes a moving image of a certain time (hereinafter referred to as “a certain time after the measuring operation”) as a specific time after the measuring operation time. That is, the end time of the measurement-related moving image 45c is a certain time after the measurement operation after the end time of the measurement operation.

  In general, even if alcohol measurement is not fraudulent, preparation before measurement (for example, preparation of a driver's license for identifying the person 90 to be measured, preparation of a mouthpiece 24a for inhaling exhalation, etc.) )) And requires more time before measurement than after measurement. Therefore, when fraud is performed before the measurement, the total time of the time when the fraud is performed and the pre-measurement preparation time is present before the measurement. On the other hand, when fraud is performed after measurement, the time during which fraud is performed exists after measurement. Therefore, if the fixed time before the measurement operation is set longer than the fixed time after the measurement operation, the fraudulent site is more likely to have the measurement-related video 45c than the fixed time before the measurement operation is shorter than the fixed time after the measurement operation. The possibility of being included in is improved.

  As shown in FIG. 4, the storage unit 45 stores related data information 45 d including data related to the measurement operation (hereinafter referred to as “related data”) for each measurement operation.

  FIG. 7 is a diagram illustrating an example of the related data information 45d.

  The related data information 45d shown in FIG. 7 includes the ID of the person to be measured, the name of the person to be measured, the execution time of the alcohol measurement, the result of the alcohol measurement, and a link to the corresponding measurement related video 45c. Yes. For example, in the example shown in FIG. 7, the alcohol measurement performed on “July 4, 2016, 7:19:20” is an alcohol measurement for the measurement subject with ID “1” and name “Taro Tokai”. As a result of alcohol measurement, the alcohol concentration is 0.000 mg / L.

  The alcohol measurement execution time is the end time of the measurement operation. Moreover, the result of alcohol measurement is that alcohol measurement is stopped, not alcohol concentration, when alcohol measurement is stopped.

  As shown in FIG. 4, the storage unit 45 stores pre-measurement fixed time information 45e indicating a fixed pre-measurement operation time, and post-measurement fixed time information 45f indicating a fixed post-measurement operation time. ing. For example, the default values of the fixed time information 45e before the measurement operation and the fixed time information 45f after the measurement operation are 10 seconds and 5 seconds, respectively.

  The storage unit 45 is capable of storing a moving image (hereinafter referred to as “always-captured moving image”) 45g that is always captured by the Web camera 31 and that includes the sound acquired by the microphone 32 in synchronization. The upper limit of the time of the always-moving moving image 45g is a specific time that is equal to or longer than the maximum time that can be taken by the measurement-related moving image 45c (hereinafter referred to as “always-captured moving image upper limit time”). In other words, the always-moving moving image 45g is a moving image from the time before the upper limit time of the always-shooting moving image to the present at the longest.

  The control unit 46 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) storing a program and various data, and a RAM (Random Access Memory) used as a work area of the CPU. Yes. The CPU executes a program stored in the ROM or the storage unit 45.

  The control unit 46 executes the alcohol measurement moving image storage program 45a stored in the storage unit 45 to thereby set a time setting unit 46a capable of setting a certain time before the measurement operation and a certain time after the measurement operation, and the Web camera 31. It functions as a moving image storage means 46b for storing the measurement related moving image 45c photographed by the above for each measurement operation, and a list display means 46c for displaying a list of the measurement related moving images 45c stored by the moving image storage means 46b.

  Next, the operation of the computer 40 when the fixed time before the measurement operation and the fixed time after the measurement operation are set will be described.

  A person such as an administrator of the person to be measured 90 can instruct the operation unit 41 to set a predetermined time before the measurement operation when the control unit 46 is executing the alcohol measurement moving image storage program 45a. Therefore, the time setting unit 46a stores information indicating the fixed time before the measurement operation according to the instruction from the operation unit 41 as the fixed time before the measurement operation 45e.

  Similarly, a person such as an administrator can instruct the operation unit 41 to set a fixed time after the measurement operation when the control unit 46 is executing the alcohol measurement moving image storage program 45a. Therefore, the time setting unit 46a stores information indicating the fixed time after the measurement operation according to the instruction from the operation unit 41 as the fixed time information 45f after the measurement operation.

  Next, operation | movement of the alcohol measurement system 10 in the case of performing alcohol measurement is demonstrated.

  FIG. 8 is a sequence diagram of the operation of the alcohol measurement system 10 when performing alcohol measurement.

  As shown in FIG. 8, when the control unit 46 is executing the alcohol measurement moving image storage program 45a and the display unit 22 displays that the ID 90 is waiting for the ID, The ID of the measurer 90 can be input from the operation unit 21 (S101).

  Note that when the alcohol measurement moving image storage program 45a is executed, the control unit 46 always captures a moving image on the storage unit 45 based on the video captured by the Web camera 31 and the sound acquired by the microphone 32. Continue to update 45g. Here, when the time of the constantly photographed moving image 45g exceeds the constantly photographed movie moving image upper limit time, the control unit 46 deletes the portion of the constantly photographed movie 45g before the always photographed movie moving upper limit time, thereby removing the time of the constantly photographed movie 45g. Is limited to the maximum time limit for recording videos.

  When an ID is input from the operation unit 21 in S101, the control unit 26 transmits the ID input from the operation unit 21 to the computer 40 (S102).

  Next, the control unit 46 confirms whether or not the ID transmitted in S102 is included in the user information table 45b (S103).

  When the control unit 46 confirms in S103 that the ID transmitted in S102 is included in the user information table 45b, the control unit 46 notifies the alcohol measuring device 20 that it is a registered ID (S104). Therefore, the control part 26 displays the instruction | indication of breath blowing on the display part 22 (S105). That is, alcohol measurement can be performed in the alcohol measuring device 20.

  When the control unit 46 confirms in S103 that the ID transmitted in S102 is not included in the user information table 45b, the control unit 46 notifies the alcohol measuring device 20 that the ID is not registered. Therefore, the control unit 26 displays on the display unit 22 that the ID is not registered. Then, when a specific operation is input to the operation unit 21, the control unit 26 displays again on the display unit 22 that the ID is waiting to be input.

  When the instruction to breathe in is displayed on the display unit 22, the person under measurement 90 can breathe into the mouthpiece 24a attached to the sensor unit 24 (S106). In addition, the measurement subject 90 can attach the measurement subject 90's own mouthpiece 24a to the sensor unit 24 at any timing before inhaling the mouthpiece 24a.

  After the process of S105, the control unit 26 starts insufflation in S106 within a specific time such as 30 seconds, and when the exhaled air in S106 continues for a specific time such as 5 seconds, Based on the alcohol concentration signal input from the sensor unit 24, the alcohol concentration in expiration is acquired (S107). Here, the control unit 26 determines whether or not exhalation is blown into the mouthpiece 24 a based on the exhalation pressure signal input from the sensor unit 24. When the alcohol concentration in the breath is 0.00 mg / L, the alcohol concentration signal input from the sensor unit 24 to the control unit 26 is zero. There is no need to calculate the alcohol concentration based on the concentration signal. Therefore, when the alcohol concentration in expiration is 0.00 mg / L, the control unit 26 can acquire the alcohol concentration in expiration in an instant. On the other hand, when the alcohol concentration in the breath is greater than 0.00 mg / L, the control unit 26 needs to calculate the alcohol concentration based on the alcohol concentration signal input from the sensor unit 24. Therefore, the alcohol concentration in the breath For example, a specific time such as 10 seconds is required as the calculation time for obtaining the value.

  After the process of S107, the control unit 26 displays the alcohol concentration acquired in S107 on the display 22b (S108) and transmits it to the computer 40 (S109). Note that after the process of S109, the control unit 26 performs a specific process on the sensor unit 24 so that the sensor unit 24 can detect the alcohol concentration again, and then waits for input of an ID. Is displayed on the display unit 22 again.

  When receiving the alcohol concentration transmitted in S109, the moving image storage unit 46b stores the measurement related moving image 45c related to the current measurement operation in the storage unit 45 (S110). Here, the moving image storage means 46b generates a measurement related moving image 45c related to the current measurement operation by copying a part of the constantly photographed moving image 45g.

  After the process of S110, the moving image storage means 46b confirms the ID confirmed in S103, that is, the ID of the person to be measured, and the name associated with this ID in the user information table 45b, that is, the name of the person to be measured. And the reception time of the alcohol concentration transmitted in S109, that is, the alcohol measurement execution time, the alcohol concentration transmitted in S109, that is, the result of alcohol measurement, and the measurement-related moving image 45c stored in S110. Related data including the link is added to the related data information 45d (S111). Note that the moving image storage means 46b uses the time indicated by a clock (not shown) in the computer 40 when the alcohol concentration is transmitted in S109 as the reception time of the alcohol concentration transmitted in S109.

  When the alcohol concentration acquired in S107 is equal to or higher than the specific concentration, the control unit 26 not only displays the alcohol concentration in S108 but also outputs a warning sound through the speaker 23. Similarly, the control unit 46 outputs a warning sound through the speaker 43 when the alcohol concentration acquired in S107 is equal to or higher than a specific concentration.

  In addition, after the process of S105, when exhalation is not performed for a specific time such as 30 seconds, for example, the operation after S131 shown in FIG. 9 is executed instead of the operation after S107 shown in FIG. .

  As shown in FIG. 9, after the process of S105, the control unit 26 displays a time-out on the display unit 22 when exhalation is not performed for a specific time such as 30 seconds (S131). Then, the computer 40 is notified (S132). In addition, after the process of S132, the control unit 26 performs a specific process on the sensor unit 24 so that the sensor unit 24 can detect the alcohol concentration again, and then waits for input of an ID. Is displayed on the display unit 22 again.

  When the time-out is notified in S132, the moving image storage unit 46b stores the measurement related moving image 45c related to the current measurement operation in the storage unit 45 (S133). Here, the moving image storage means 46b generates a measurement related moving image 45c related to the current measurement operation by copying a part of the constantly photographed moving image 45g.

  After the process of S133, the moving image storage unit 46b confirms the ID confirmed in S103, that is, the ID of the measured person, and the name associated with this ID in the user information table 45b, that is, the name of the measured person. And the time when the time-out is notified in S132, that is, the alcohol measurement execution time, the result of alcohol measurement, that is, the result that the measurement operation is terminated due to the time-out, and the measurement-related moving image stored in S133. Related data including the link to 45c is added to the related data information 45d (S134). The moving image storage means 46b uses the time indicated by a clock (not shown) in the computer 40 when the time-out is notified in S132, as the time when the time-out is notified in S132. .

  The control unit 26 outputs a warning sound through the speaker 23 when the measurement operation is terminated halfway. Similarly, the control unit 46 outputs a warning sound from the speaker 43 when the measurement operation is terminated halfway.

  In the above, the case where the measurement operation is terminated halfway due to a timeout has been described. However, the alcohol measurement system 10 also performs the measurement operation when the measurement operation is terminated halfway due to a reason other than a timeout, such as when the measurement operation is terminated halfway by an instruction from the operation unit 21. Is stored in the storage unit 45, and the cause of the end of the current measurement operation is included as a result of the alcohol measurement. The related data is added to the related data information 45d.

  Next, the operation of the computer 40 when the administrator confirms the result of alcohol measurement will be described.

  The administrator can instruct the computer 40 to browse the result of alcohol measurement via the operation unit 41.

  When the browsing of the alcohol measurement result is instructed, the list display unit 46c displays the list 50 (see FIG. 10) based on the related data information 45d on the display unit 42.

  FIG. 10 is a diagram illustrating an example of the list 50 displayed on the display unit 42.

  The list 50 shown in FIG. 10 is almost the same as the related data information 45d shown in FIG. The list 50 includes “measurement operation time” obtained by subtracting a certain time before the measurement operation and a certain time after the measurement operation from the length of the measurement-related moving image 45c. The measurement operation time may also be included in the related data information 45d. The list 50 displays whether or not the measurement operation time is a specific time or more. In the list 50 shown in FIG. 10, information on the measurement operation having the measurement operation time of 30 seconds or more is drawn in black and white.

  The administrator can check various information included in the list 50 displayed on the display unit 42. In particular, the administrator can instruct the computer 40 to reproduce the measurement-related moving image 45c by selecting a link to the measurement-related moving image 45c in the list 50 displayed on the display unit 42.

  When the reproduction of the measurement related moving image 45 c is instructed, the control unit 46 reproduces the instructed measurement related moving image 45 c by the display unit 42 and the speaker 43.

  Accordingly, the administrator confirms the measurement-related moving image 45c reproduced by the display unit 42 and the speaker 43, so that the measured person 90 shown in the measurement-related moving image 45c is displayed in the “name of measured person” column of the list 50. It can be confirmed that there is no fraudulent activity, such as the identity of the person indicated in.

  As described above, the alcohol measurement system 10 uses the measurement operation time, the specific time before the measurement operation start time, that is, the fixed time before the measurement operation, and the measurement operation end time. A measurement-related moving image 45c of a series of time consisting of a specific time later, that is, a fixed time after the measurement operation is stored. Therefore, the alcohol measurement system 10 does not cause the conventional problem that “a part highly relevant to the measurement operation is not easily identified in the moving image”. Therefore, the alcohol measurement system 10 can make it easier for the administrator of the person to be measured 90 to identify an illegal act with respect to alcohol measurement from the moving image than before.

  Here, there are various illegal acts as the illegal acts identified from the measurement-related moving image 45c. For example, there is a fraud that simply causes a person who substitutes for the person 90 to perform alcohol measurement for the person 90 to be measured. Further, the alcohol measuring device 20 includes a tube in which exhaled breath can be improperly attached to the alcohol measuring device 20 even when the measured subject 90 holds the mouthpiece 24a. An illegal modification is made to the person 90 who is holding the mouthpiece 24a, and the person who substitutes for the person 90 is out of the shooting range of the Web camera 31 while leaving the moving image. There is an act. In addition, by preparing the dummy mouthpiece 24a, the video of the person 90 to be measured holding the dummy mouthpiece 24a is left, and the real person from the person in charge of the person 90 to be measured outside the shooting range of the Web camera 31. There is an illegal act in which exhalation is blown into the mouthpiece 24a. It should be noted that the dishonest act using the dummy mouthpiece 24a is that when the sensor unit 24 appears in the shooting range of the Web camera 31, not only the dummy mouthpiece 24a but also the dummy mouthpiece 24a to which the dummy mouthpiece 24a is attached. A sensor unit 24 is prepared.

  Since the alcohol measurement system 10 stores the measurement-related moving image 45c, when the alcohol concentration is equal to or higher than a specific concentration, whether the measurement subject 90 has confirmed the alcohol concentration displayed on the display 22b, etc. Whether the 90 has acted appropriately can be confirmed by the measurement-related moving image 45c.

  The alcohol measurement system 10 has a time from the start time of the measurement related video 45c to the start time of the measurement operation, that is, a certain time before the measurement operation, and from the end time of the measurement operation to the end time of the measurement related video 45c. The time, that is, the fixed time after the measurement operation is the fixed time. With this configuration, the alcohol measurement system 10 measures the time from the start time of the measurement related video 45c to the start time of the measurement operation and the time from the end time of the measurement operation to the end time of the measurement related video 45c. Compared to the configuration that changes for each video 45c, the uniformity of the length of time of the measurement-related video 45c can be improved. Therefore, the work for checking the measurement-related video 45c in order to find fraud against alcohol measurement Efficiency can be improved.

  The alcohol measurement system 10 does not notify that the current time is during the shooting time for the measurement-related moving image 45c. With this configuration, the alcohol measurement system 10 can give a mental pressure that a person who wants to perform an illegal act on alcohol measurement may be performing shooting for the measurement-related video 45c. It is difficult to carry out fraudulent actions against alcohol measurement. Therefore, the alcohol measurement system 10 can suppress the occurrence of fraudulent acts with respect to alcohol measurement.

  The alcohol measurement system 10 does not notify that the shooting time for the measurement-related moving image 45c is in progress, and how much time before or after the measurement operation time is stored in the measurement-related moving image 45c. Can be changed by a person such as an administrator of the person to be measured 90, so that a person who wants to execute an illegal act on alcohol measurement may be performing shooting for the measurement related video 45c. Can be effectively applied. Therefore, the alcohol measurement system 10 can further suppress the occurrence of fraudulent acts with respect to alcohol measurement.

  Since the alcohol measurement system 10 stores the measurement-related moving image 45c in association with the alcohol measurement result, the measurement-related moving image 45c can be selected according to the alcohol measurement result. Accordingly, the alcohol measurement system 10 selects the measurement-related moving image 45c whose alcohol measurement result is equal to or lower than a specific alcohol concentration, for example, 0.00 mg / L, from among a large number of measurement-related moving images 45c. The measurement-related moving image 45c can easily find “a case in which an alcohol concentration lower than the actual alcohol concentration in the breath of the measurement subject 90 is measured due to an illegal act on the measurement”.

  When the measurement operation is terminated halfway, it is highly possible that an illegal act for alcohol measurement has been performed, compared to the case where the measurement operation is completed normally. Since the alcohol measurement system 10 stores the measurement-related moving image 45c when the measurement operation ends in the middle, it is possible to improve the possibility that the measurement-related moving image 45c finds an illegal act for alcohol measurement.

  When the measurement operation time is long, there is a high possibility that fraudulent acts on alcohol measurement are being performed compared to when the measurement operation time is short. The alcohol measurement system 10 uses the measurement-related moving image 45c in which the measurement operation time is longer than a specific time, that is, the measurement-related moving image 45c in which the measurement operation time is longer than the measurement-related moving image 45c. Since the moving image 45c, that is, the measurement-related moving image 45c having a short measurement operation time is displayed in the list 50, the measurement-related moving image 45c having a long measurement operation time can be easily selected from the many measurement-related moving images 45c. Can be elected. In addition, since the alcohol measurement system 10 displays the measurement operation time in the list 50, the measurement-related video 45c having a long measurement operation time can be easily selected from the many measurement-related videos 45c. it can. Therefore, the alcohol measurement system 10 can easily find an illegal act against the alcohol measurement by the measurement related moving image 45c. The list display means 46c may display the list 50 without distinguishing whether the measurement operation time is the measurement-related moving image 45c having a specific time or more, or the length of the measurement operation time. The list 50 may not be displayed.

  Since the alcohol measurement system 10 can confirm whether or not an illegal act for alcohol measurement has been executed by the sound included in the measurement-related video 45c, the alcohol measurement system 10 confirms that the fraud for alcohol measurement is identified from the measurement-related video 45c. Can be facilitated.

  Since the alcohol measurement system 10 can include a sound in the measurement-related moving image 45c, the alcohol measurement system 10 measures a warning sound when the alcohol concentration is equal to or higher than a specific concentration and a warning sound when the measurement operation is terminated halfway. It can be included in the related video 45c. Accordingly, the alcohol measurement system 10 determines whether the subject 90 has acted appropriately, such as whether the subject 90 has confirmed the alcohol concentration displayed on the display 22b when the alcohol concentration is equal to or higher than a specific concentration. Can be confirmed by the measurement-related moving image 45c. For example, when the alcohol concentration is higher than a specific concentration, the alcohol measurement system 10 can include a warning sound when the alcohol concentration is higher than the specific concentration in the measurement-related moving image 45c. It is possible to counter the false claim of the person under measurement 90 that the alcohol concentration was not confirmed because there was not.

  In the present embodiment, the alcohol measurement system 10 generates the measurement-related moving image 45c including both the fixed time before the measurement operation and the fixed time after the measurement operation. However, the alcohol measurement system 10 may generate the measurement-related moving image 45c including the measurement operation time and either one of the fixed time before the measurement operation and the fixed time after the measurement operation.

  In the present embodiment, the computer 40 stores various data such as the measurement related moving image 45c and the related data information 45d in the storage unit 45. However, the computer 40 stores at least a part of various data such as the measurement related moving image 45c and the related data information 45d in a device other than the computer 40 such as another computer in the network to which the computer 40 participates. Also good.

  The alcohol measurement system 10 stores a measurement-related moving image 45c for each measurement operation. However, the alcohol measurement system 10 may be able to set whether or not to save the measurement-related moving image 45c for each measurement operation according to an instruction from the operation unit 41.

  The alcohol measurement system 10 includes a mouthpiece 24a as an exhalation inhaling part into which exhaled breath is infused by the measurement subject 90. However, the alcohol measurement system 10 may include an exhalation blowing unit that is not a mouthpiece. For example, the alcohol measurement system 10 may include an exhalation inhalation unit that exhales when exhaled air is blown by the measurement subject 90 instead of the exhalation inhalation unit given by the measurement subject 90.

  The web camera 31 may be disposed at a location other than the location illustrated in FIG. 1 as long as the web camera 31 is disposed at a position where the measurement subject 90 in a state where breath is being blown into the mouthpiece 24a can be photographed. For example, the web camera 31 may be integrated with either the alcohol measuring device 20 or the computer 40.

  The alcohol measurement system 10 outputs a warning sound from the speaker 23 and the speaker 43, but outputs an alarm sound when the alcohol concentration is equal to or higher than a specific concentration or when the measurement operation is terminated halfway. A machine may be provided in addition to the speaker 23 and the speaker 43 or in place of at least one of the speaker 23 and the speaker 43.

  The microphone 32 may be arranged at a location other than the location shown in FIG. 1 as long as the microphone 32 is arranged at a position where the sound in the vicinity of the measurement subject 90 in the state of breathing into the mouthpiece 24a can be acquired. . For example, the microphone 32 may be integrated with any one of the alcohol measuring device 20, the web camera 31, and the computer 40. Note that the alcohol measurement system 10 may not include the microphone 32.

  The alcohol measurement system 10 is configured to specify the measurement subject 90 by manually inputting the user's ID from the operation unit 21. However, the alcohol measurement system 10 may identify the person 90 to be measured by other methods. For example, the alcohol measurement system 10 includes an image scanner that reads an image drawn on the surface of a card such as a driver's license, and character information is extracted from an image read by the image scanner by OCR (Optical Character Recognition). Then, the person to be measured 90 associated with the extracted character information in advance may be specified. In addition, the alcohol measurement system 10 includes an IC card reader that reads information from an IC card such as an IC (Integrated Circuit) card, such as a driver's license, and associates the information with the information read by the IC card reader in advance. The measured person 90 may be specified. In addition, the alcohol measurement system 10 includes a biological information acquisition device that acquires biological information such as finger veins, and identifies the measurement subject 90 that is associated in advance with the biological information acquired by the biological information acquisition device. You may do it.

  In the alcohol measurement system 10, the alcohol measurement device 20 may execute at least a part of the functions of the computer 40. The alcohol measurement system 10 may not include the computer 40 when the alcohol measuring device 20 executes all the functions of the computer 40.

(Second Embodiment)
First, the configuration of the alcohol measurement system according to the second embodiment of the present invention will be described.

  In the configuration of the alcohol measurement system according to the present embodiment, the alcohol measurement system 10 (see FIG. 1) according to the first embodiment is replaced with a computer 240 (see FIG. 11) instead of the computer 40 (see FIG. 4). ).

  FIG. 11 is a block diagram of computer 240 of the alcohol measurement system according to the present embodiment.

  As shown in FIG. 11, the computer 240 has a configuration in which the computer 40 (see FIG. 4) stores the alcohol measurement movie storage program 245 a in the storage unit 45 instead of the alcohol measurement movie storage program 45 a (see FIG. 4). It is the same.

  The control unit 46 executes the alcohol measurement moving image storage program 245a stored in the storage unit 45 to thereby start the measurement related moving image 245c in addition to the time setting unit 46a, the moving image storage unit 46b, and the list display unit 46c. To the start time of the measurement operation (hereinafter referred to as “specific time before the measurement operation”) and the time from the end time of the measurement operation to the end time of the measurement-related video 245c (hereinafter “after the measurement operation”). It functions as time determination means 246a for determining each measurement-related moving image 245c.

  FIG. 12 is a diagram illustrating a configuration of the measurement related moving image 245c.

  As shown in FIG. 12, the measurement-related moving image 245c includes a moving image of a specific time before the measuring operation instead of the moving image of the fixed time before the measuring operation, and instead of the moving image of the fixed time after the measuring operation. It is the same as the measurement related moving image 45c (see FIG. 6) except that it includes a moving image of a specific time after the measurement operation.

  Next, the operation of the alcohol measurement system according to the present embodiment will be described.

  The operation of the alcohol measurement system according to the present embodiment is the same as the operation of the alcohol measurement system 10 according to the first embodiment, except for the operations described below.

  In the alcohol measurement system 10, the specific time before the measurement operation is a fixed time that is a certain time before the measurement operation. However, in the alcohol measurement system according to the present embodiment, the measurement pre-operation specific time is determined for each measurement-related moving image 245c.

  As a pattern for determining the specific time before the measurement operation, for example, a pattern in which the fixed time before the measurement operation is a specific time before the measurement operation (hereinafter referred to as “pattern A”) as in the first embodiment. And a pattern (hereinafter referred to as “pattern B”) that is added or subtracted for each measurement-related moving image 245c for a certain time with respect to the previous specific time before the measurement operation, and the previous specific time before the measurement operation A pattern (hereinafter referred to as “pattern C”) that is added or subtracted for each measurement-related moving image 245c for a certain ratio of a certain time before the measurement operation, and a certain time before the measurement operation for a random time within a certain range. A pattern in which the time added or subtracted to the specific time before the measurement operation (hereinafter referred to as “pattern D”) and a random time within a certain ratio range of the fixed time before the measurement operation are measured. A pattern (hereinafter referred to as “pattern E”) in which the time added or subtracted to the previous fixed time is set as the specific time before the measurement operation, and a constant coefficient with respect to the previous specific time before the measurement operation is measured-related moving image 245c. A pattern (hereinafter referred to as “pattern F”) that is multiplied or divided every time, and a pattern (hereinafter referred to as “specific time before measurement operation”) that is selected at random from a plurality of types of times set by a person such as an administrator. "Pattern G") and a pattern (hereinafter referred to as "Pattern H") in which a time randomly selected from within a specific time range set by a manager or the like is set as the specific time before the measurement operation. And a pattern (hereinafter referred to as “Pattern”), which is a time randomly selected from a plurality of fixed times that cannot be referred to by an administrator or the like. I ”.) And a pattern (hereinafter referred to as“ pattern J ”), which is a time that is randomly selected from a fixed specific time range that cannot be referred to by an administrator or the like. Can be said.)

  The specific time before the measurement operation has been described above. However, in the alcohol measurement system according to the present embodiment, the specific time after the measurement operation can be determined for each measurement-related moving image 245c in the same manner as the specific time before the measurement operation.

  The time determination unit 246a sets a pattern for determining the pre-measurement specific time and the post-measurement specific time according to an instruction via the operation unit 41 or the communication unit 44. The time determination unit 246a uses the pattern for determining the pre-measurement operation specific time that is set in advance when the video storage unit 46b stores the measurement-related video 245c in the storage unit 45 in S110 or S133. The specific time is determined, and the post-measurement operation specific time is determined by a predetermined pattern for determining the post-measurement operation specific time. In S110 or S133, the moving image storage unit 46b stores the measurement related moving image 245c in the storage unit 45 according to the specific time before the measurement operation and the specific time after the measurement operation determined by the time determination unit 246a.

  Hereinafter, the patterns A to J for determining the specific time before the measurement operation will be described in detail.

Pattern A Pattern A is a pattern in which a certain time before the measurement operation is set as the specific time before the measurement operation, as in the first embodiment. The alcohol measurement system according to the present embodiment measures the time from the start time of the measurement-related moving image 245c to the start time of the measurement operation when the pattern A is set as the pattern for determining the specific time before the measurement operation. Compared to the configuration that changes for each related video 245c, the uniformity of the length of time of the measurement related video 245c can be improved, so that the measurement related video 245c is confirmed in order to find fraud against alcohol measurement. Work efficiency can be improved.

Pattern B Pattern B is a pattern that is added or subtracted for each measurement-related moving image 245c for a predetermined time with respect to the previous specific time before the measurement operation.

For example, when the fixed time before the measurement operation is 10 seconds and the fixed time to be added for each measurement-related moving image 245c is 1 second, the time determination unit 246a starts the specific time before the measurement operation from the fixed time before the measurement operation. Then, every time the measurement related moving image 245c is stored by the moving image storage means 46b, 1 second is added to the previous specific time before the measurement operation, and if a specific value, for example, 15 seconds is exceeded, the measurement is performed. The process of returning the specified pre-operation time to a fixed time before the measurement operation is repeated. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c as follows.
10 seconds → 11 seconds → 12 seconds → 13 seconds → 14 seconds → 15 seconds Repeat from 10 seconds.

  The above is an example of addition. However, the time determination unit 246a starts the specific time before the measurement operation from a certain time before the measurement operation, and before the measurement operation moving image 245c is stored by the moving image storage unit 46b, before the previous measurement operation. The process of subtracting 1 second from the specific time and returning the specific time before the measurement operation to a certain time before the measurement operation when the value falls below a specific value, for example, 5 seconds, may be repeated.

  In the alcohol measurement system according to the present embodiment, when the pattern B is set as a pattern for determining the specific time before the measurement operation, the specific time before the measurement operation is changed for each measurement-related moving image 245c. Compared to the case where the pattern A is set as the pattern for determining the specific time before the operation, it may be difficult for the person who wants to execute an illegal act for alcohol measurement to grasp the start time of the measurement related video 245c. it can.

Pattern C Pattern C is a pattern that is added or subtracted for each measurement-related moving image 245c for a certain ratio of a certain period of time before the measurement operation to the previous specific time before the measurement operation. The pattern C is the same as the pattern B except that the time to be added or subtracted for each measurement-related moving image 245c is a time corresponding to a certain ratio of the certain time before the measurement operation.

For example, when the fixed time before the measurement operation is 20 seconds and the fixed ratio is 10%, the time corresponding to the fixed ratio of the fixed time before the measurement operation is 2 seconds (= 20 seconds × 10%). The means 246a starts the specific time before the measurement operation for a certain time before the measurement operation, and each time the processing for saving the measurement related moving image 245c by the moving image storage means 46b is executed, 2 seconds, and when a specific value, for example, 30 seconds is exceeded, the process of returning the specific time before the measurement operation to the fixed time before the measurement operation is repeated. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c as follows.
20 seconds-> 22 seconds-> 24 seconds-> 26 seconds-> 28 seconds-> 30 seconds After that, it repeats from 20 seconds.

  The above is the case of addition. However, the time determination unit 246a starts the specific time before the measurement operation from a certain time before the measurement operation, and before the measurement operation moving image 245c is stored by the moving image storage unit 46b, before the previous measurement operation. The process of subtracting 2 seconds from the specific time and returning the specific time before the measurement operation to a certain time before the measurement operation when the value falls below a specific value, for example, 10 seconds, may be repeated.

  In the alcohol measurement system according to the present embodiment, when the pattern C is set as the pattern for determining the specific time before the measurement operation, the time to add or subtract for each measurement-related moving image 245c is the fixed time before the measurement operation. Since the time is a fixed ratio, the pre-measurement operation specific time that is moderate with respect to the fixed time before the measurement operation compared to the case where the pattern B is set as the pattern for determining the pre-measurement operation specific time. Can be determined.

Pattern D Pattern D is a pattern in which a time obtained by adding or subtracting a certain time before the measurement operation for a random time within a certain range is a specific time before the measurement operation.

For example, when the fixed time before the measurement operation is 20 seconds and the fixed range is 0 to 5 seconds, the time determination unit 246a performs the measurement every time the measurement related moving image 245c is stored by the moving image storage unit 46b. The specified pre-operation specific time is irregularly changed between 20 and 25 seconds (= 20 seconds + (0 to 5 seconds)). That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c, for example, as follows.
21 seconds → 25 seconds → 20 seconds → 22 seconds ...

  The above is the case of addition. However, the time determination unit 246a may perform subtraction or may randomly switch between addition and subtraction. For example, when the predetermined time before the measurement operation is 20 seconds and the predetermined range is 0 to 5 seconds, the time determination unit 246a executes the process of storing the measurement related moving image 245c by the moving image storage unit 46b when subtracting. When the specific time before the measurement operation is irregularly changed between 15 and 20 seconds (= 20 seconds-(0 to 5 seconds)), and addition and subtraction are switched randomly, measurement by the moving image storage means 46b Each time the related moving image 245c is stored, the specific time before the measurement operation is irregularly changed between 15 and 25 seconds (= 20 seconds ± (0 to 5 seconds)).

  In the alcohol measurement system according to the present embodiment, when the pattern D is set as a pattern for determining the specific time before the measurement operation, the specific time before the measurement operation is randomly changed for each measurement-related moving image 245c. Compared to the case where pattern B or pattern C is set as a pattern for determining the specific time before the measurement operation, the person who wants to execute an illegal act on alcohol measurement can grasp the start time of the measurement related video 245c. Can be difficult.

Pattern E Pattern E is a pattern in which a specific time before the measurement operation is set to a time obtained by adding or subtracting a predetermined time before the measurement operation for a random time within a certain ratio range of the predetermined time before the measurement operation. The pattern E is the same as the pattern D except that the time to be added to or subtracted from the fixed time before the measurement operation is a random time within the fixed ratio range of the fixed time before the measurement operation.

For example, when the fixed time before the measurement operation is 20 seconds and the fixed ratio range is 30%, the time of the fixed ratio range is 0 to 6 seconds (= 20 seconds × 30%). Each time the process of saving the measurement-related moving image 245c by the moving image storage means 46b is executed, the specific time before the measurement operation is irregularly changed between 20 to 26 seconds (= 20 seconds + (0 to 6 seconds)). To do. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c, for example, as follows.
22 seconds → 26 seconds → 20 seconds → 23 seconds ...

  The above is the case of addition. However, the time determination unit 246a may perform subtraction or may randomly switch between addition and subtraction. For example, if the fixed time before the measurement operation is 20 seconds and the fixed ratio range is 30%, the time determination unit 246a performs the subtraction process every time the measurement related moving image 245c is stored by the moving image storage unit 46b. In addition, when the specific time before the measurement operation is irregularly changed between 14 and 20 seconds (= 20 seconds-(0 to 6 seconds)) and the addition and subtraction are switched randomly, the measurement related by the moving image storage means 46b Each time the process of saving the moving image 245c is executed, the specific time before the measurement operation is irregularly changed between 14 to 26 seconds (= 20 seconds ± (0 to 6 seconds)).

  In the alcohol measurement system according to the present embodiment, when the pattern E is set as the pattern for determining the specific time before the measurement operation, the time to add or subtract to the certain time before the measurement operation is the fixed time before the measurement operation. Therefore, when the pattern D is set as a pattern for determining the specific time before the measurement operation, the time before the measurement operation is moderate with respect to the certain time before the measurement operation. A specific time can be determined.

Pattern F The pattern F is a pattern in which a constant coefficient is multiplied or divided for each measurement-related moving image 245c with respect to the previous specific time before the measurement operation.

For example, when the fixed time before the measurement operation is 20 seconds and the fixed coefficient to be multiplied for each measurement-related moving image 245c is 0.9, the time determination unit 246a sets the specific time before the measurement operation as the fixed time before the measurement operation. Starting from the above, every time the process of storing the measurement-related moving image 245c by the moving image storage means 46b is executed, the previous specific time before the measurement operation is multiplied by 0.9, and is less than a specific value, for example, 10 seconds. The process of returning the specific time before the measurement operation to a certain time before the measurement operation is repeated. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c as follows.
20 seconds-> 18 seconds-> 16.2 seconds-> 14.6 seconds-> 13.1 seconds-> 11.8 seconds-> 10.6 seconds After that, it repeats from 20 seconds.

  The above is an example of multiplication. However, the time determination unit 246a starts the specific time before the measurement operation from a certain time before the measurement operation, and before the measurement operation moving image 245c is stored by the moving image storage unit 46b, before the previous measurement operation. The process of dividing 0.9 by the specific time and returning the specific time before the measurement operation to a certain time before the measurement operation when a specific value, for example, 30 seconds is exceeded may be repeated.

  In the above description, a number smaller than 1 is described as an example of the coefficient. However, the coefficient may be a number of 1 or more.

  In the alcohol measurement system according to the present embodiment, when the pattern F is set as the pattern for determining the specific time before the measurement operation, the specific time before the measurement operation is changed for each measurement-related moving image 245c. Compared to the case where the pattern A is set as the pattern for determining the specific time before the operation, it may be difficult for the person who wants to execute an illegal act for alcohol measurement to grasp the start time of the measurement related video 245c. it can. In addition, in the alcohol measurement system according to the present embodiment, when the pattern F is set as a pattern for determining the specific time before the measurement operation, the time to increase or decrease for each measurement-related moving image 245c is set to a certain time before the measurement operation. Since it is the time calculated as the reference, the pre-measurement operation specific operation is appropriate for a certain time before the measurement operation compared to the case where the pattern B is set as the pattern for determining the pre-measurement operation specific time. Time can be determined.

-About Pattern G Pattern G is a pattern in which a time randomly selected from a plurality of types of time set by a manager or the like is used as the specific time before the measurement operation.

For example, when a plurality of types of time set by a person such as an administrator are 10 seconds, 15 seconds, and 20 seconds, the time determination unit 246a performs a process of storing the measurement related moving image 245c by the moving image storage unit 46b. Each time, the specific time before the measurement operation is randomly changed to any one of 10 seconds, 15 seconds, and 20 seconds. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c, for example, as follows.
10 seconds → 20 seconds → 15 seconds → 20 seconds ...

  The above is a case where there are three types of time set by a person such as an administrator. However, the type of time set by a person such as an administrator may be plural other than three.

  When the pattern G is set as the pattern for determining the specific time before the measurement operation, the alcohol measurement system according to the present embodiment randomly changes the specific time before the measurement operation for each measurement-related moving image 245c. Compared to the case where pattern B or pattern C is set as a pattern for determining the specific time before the measurement operation, the person who wants to execute an illegal act on alcohol measurement can grasp the start time of the measurement related video 245c. It can be made more difficult.

-About Pattern H Pattern H is a pattern in which a time randomly selected from within a specific time range set by a manager or the like is used as the specific time before the measurement operation. The pattern H is the same as the pattern G except that the object to be selected at random is a time within the time range.

For example, when the time range set by a person such as an administrator is 10 to 20 seconds, the time determination unit 246a uses the measurement-use moving image 245c by the moving image storage unit 46b every time the measurement-related moving image 245c is stored. The specific time before operation is randomly changed between 10 and 20 seconds. That is, the time determination unit 246a changes the specific time before the measurement operation for each measurement-related moving image 245c, for example, as follows.
10 seconds → 19 seconds → 20 seconds → 13 seconds → 15 seconds → 11 seconds → 18 seconds ...

  In the alcohol measurement system according to the present embodiment, when the pattern H is set as the pattern for determining the specific time before the measurement operation, the time randomly selected from a plurality of types of time set by a person such as an administrator Instead, since the time randomly selected from the specific time range set by the administrator or the like is set as the specific time before the measurement operation, the pattern G is set as a pattern for determining the specific time before the measurement operation. Compared with the case where it is possible to improve the randomness of the specific time before the measurement operation, as a result, it is possible to grasp the start time of the measurement related video 245c for a person who wants to execute an illegal act on alcohol measurement. It can be made more difficult.

Pattern I Pattern I is a pattern in which a time randomly selected from a plurality of fixed times that cannot be referred to by an administrator or the like is a specific time before the measurement operation. For example, a plurality of types of times to be randomly selected are set to practical times by the manufacturer of the alcohol measurement system according to the present embodiment. The pattern I is the same as the pattern G except that a plurality of types of times to be selected at random are fixed times that cannot be referred to by an administrator or the like.

  In the alcohol measurement system according to the present embodiment, when pattern I is set as a pattern for determining the specific time before the measurement operation, a plurality of types of times to be randomly selected are also referred to by a manager or the like. Since there is no possibility that a person who wants to perform fraudulent acts on alcohol measurement will be known, the pattern G is set as a pattern for determining the specific time before the measurement operation. Compared with the case where it is done, it is possible to make it difficult for a person who wants to execute an illegal act on alcohol measurement to grasp the start time of the measurement-related moving image 245c.

Pattern J Pattern J is a pattern in which a time randomly selected from a fixed specific time range that cannot be referred to by a manager or the like is set as a specific time before the measurement operation. For example, the time range to be randomly selected is set to a practical time by the manufacturer of the alcohol measurement system according to the present embodiment. The pattern J is the same as the pattern H except that the time range to be randomly selected is a fixed time range that cannot be referred to by a manager or the like.

  In the alcohol measurement system according to the present embodiment, when the pattern J is set as a pattern for determining the specific time before the measurement operation, the time range to be randomly selected is also referred to by an administrator or the like. If the time range to be selected at random is not likely to be known to those who want to perform fraudulent acts on alcohol measurement, and pattern H is set as the pattern for determining the specific time before the measurement operation Compared to the above, it is possible to make it difficult for a person who wants to execute an illegal act on alcohol measurement to grasp the start time of the measurement-related moving image 245c.

  As described above, the alcohol measurement system according to the present embodiment is suitable for a person who wants to execute an illegal act on alcohol measurement when the patterns B to J are set as the pattern for determining the specific time before the measurement operation. On the other hand, by making it difficult to grasp the start time of the measurement related video 245c, it is possible to give a mental pressure that the shooting for the measurement related video 245c may be being executed. The act is difficult to execute. Therefore, the alcohol measurement system according to the present embodiment can suppress the occurrence of fraud with respect to alcohol measurement.

  Although the specific time before the measurement operation has been described above, the same applies to the specific time after the measurement operation.

  In the alcohol measurement system according to the present embodiment, the pattern for determining the specific time before the measurement operation and the pattern for determining the specific time after the measurement operation may be similar to each other, or may be completely different patterns. Also good.

  In the alcohol measurement system according to the present embodiment, the determination pattern and the length of time can be set separately for the specific time before the measurement operation and the specific time after the measurement operation. It is possible to record fraud efficiently while suppressing the file size of 245c.
