The sobriety measurement unit 312 is for performing a sobriety test on a subject classified as a sobriety test subject among subjects.

The drinking measuring unit 312 is integrally mounted on the drinking state determining device 30 and connected to the determining control unit 33, as in the present example, or is configured separately from the drinking state determining device 30 and is a drinking state determining device. (30) and can communicate wirelessly.

The breathalyzer tester 312 may input a breathalyzer measurement value obtained by measuring a drinker to the determination controller 33 .

When the drinking measuring unit 312 and the drinking state determining device 30 are wirelessly connected to each other, the drinking measuring unit 312 may include a communication unit for transmitting the drinking measurement value to the determination control unit 33 .

Like the user input unit 32 described with reference to FIG. 2 , the user input unit 32 is a command for controlling the operation of the drinking state determination device 30 by a user (eg, a manager) of the drinking state determination device 30 . , Information related to each worker (hereinafter, worker-related information is referred to as 'worker-related information') for determining the suitability of the current job for each worker is generated and inputted to the determination control unit 33. there is.

The worker-related information input from the user input unit 32 may include drinking-related information including at least one of a drinking accident history and an alcoholism treatment history of the corresponding worker, and the current job of each worker.

Such a user input unit 32 may also be composed of a key pad, a touch pad, or a mouse.

The determination control unit 33 is a control module that controls the overall operation of the drinking state determination device 30 and may also be a processor.

In this example, when the subject identity information of the subject person 10 is received from the subject terminal 20, the determination control unit 33 compares the subject identity information with the operator identity information stored in the database 35, the operator identity information It is possible to determine whether the target person is one of the workers by determining whether a worker having the same identity information as the target person's identity information is registered.

The worker identification information may include at least one of nationality, gender, name, date of birth, identification number such as resident registration number or alien registration number, and address.

If the target person 10 is a registered worker, the determination controller 33 may extract data related to the body condition of the target person 10 using the image data of the target person 10 .

The determination control unit 33 may obtain body information of the subject 10 from the data on the extracted physical state, and by using the acquired body information, the subject 10 is suspected of being in a current drinking state or a sobriety measurement is mandatory. It is possible to determine whether a person is subject to a breathalyzer test while performing a task to be received.

Accordingly, if the subject is classified as a drinking test subject, the drinking test subject may perform a drinking test using the sobriety measuring unit 312 .

The storage unit 34 is a storage medium for storing data necessary for the operation of the drinking state determination device 30 and data generated during operation, and may be a memory.

Therefore, as an example, the storage unit 34 stores image data generated by the photographing operation of the photographing unit 311 (eg, subject image data), body information of the subject 10 determined using the subject image data, and age. The normal heart rate range according to the condition, the gait of an ordinary person in a non-drinking state, the degree of shaking set, and data related to a guide message output to the video output module 361 and the audio output module 362 may be stored.

The database 35 connected to the determination control unit 33 may store information related to each operator and information related to a job (hereinafter, information related to a job is referred to as 'job related information').

Since each worker may have identification information, information related to each worker may be stored in the database 35 corresponding to the corresponding identification information.

Worker-related information is, for example, alcohol-related information of the worker (eg, at least one of a drinking accident history and alcoholism treatment history). It may include at least one of worker identity information, worker face image data, and a current job.

The worker's face image data may be image data obtained by photographing the face of each worker registered as a worker in the current workplace.

Therefore, a worker registered as a worker may be a subject 10 for determining body information. In this example, whether or not to acquire body information may be determined according to the type of job the worker is in charge of.

The current assigned task may be a task currently assigned to each worker.

The type of work in charge can be divided into height work, firearms handling work, and simple chores.

As described above, the body information determined by the determination controller 33 and stored in the object-related information may be at least one of heart rate, skin color, and gait.

The work-related information is information about each work currently being performed in the workplace, and may include whether or not a breathalyzer test is required according to at least one of the type of work, the type of work, and the degree of risk, and may additionally include an allowable drinking level according to the type of work. there is. Work types can be divided into height work, fire handling work, and simple chores.

The height work may be a work performed at a predetermined height (eg, 1 m) or higher, and the fire handling work may be a work using fire such as a welding work.

Simple chores are tasks that do not require specialization, and may include cleaning and collecting workplace garbage, removing snow, and directing traffic.

Whether or not a breathalyzer test is necessary according to the type of work may be determined according to the degree of risk of the work.

Therefore, in the case of this example, the determination control unit 33 may classify the corresponding worker as a breathalyzer subject requiring a breathalyzer test in case of work at heights and work handling firearms, and in the case of simple chores, it does not determine whether a breathalyzer test is necessary, so it is unconditional. You can do that.

In addition, the allowable drinking level may also be determined differently according to the risk of the work, and for example, when the difficulty of the work is the lowest, such as simple chores, the range of the allowable drinking level may also be the lowest.

For the type of work, details of the corresponding work may be determined according to process progress information and stored in the database 35 . Accordingly, the current job of each worker may be a job related to details determined according to the process progress information. For example, in the case of high-altitude work, the height of the work may be determined in units of a fixed period, such as work being carried out at a height of 3 floors or less during this week, and work being performed at a height of 10 floors or more during a car week.

Further, in the case of fire handling work, details such as fire work outdoors today, fire work indoors on the ground the next morning, and fire work indoors underground the next afternoon may be determined.

In the case of simple chores, the sobriety may be outdoor chores and the car owner may be indoor chores.

Depending on the details of each type of work, the risk level of the work may change, and depending on the change of risk level, whether or not a breathalyzer test is required for the work or the allowable alcohol level may be changed.

These details may be transmitted from a management server that communicates with the communication unit of the drinking state determination device 30 or may be input through the user input unit 32, and in real time under the control of the determination control unit 33, such as the database 35 It can be stored on a storage medium.

In an alternative example, the database 35 may be omitted, and in this case, the information stored in the database 35 may be stored in a storage medium provided in the drinking state determination device 30, such as the storage unit 34. there is. The output unit 36 generates output related to sight and hearing, and may include a video output module 361 and an audio output module 362.

The video output module 361 and the audio output module 362 are similar to those already described with reference to FIG. 2 , and data (e.g., video data and audio) output from the determination controller 33 according to the control of the determination controller 33 data) can output video and audio respectively.

Accordingly, the image output module 361 may output an image related to the image data acquired by the photographing unit 311 , eg, a photographed image of the skin color and gait of the subject 10 .

In addition, the image output module 361 and the sound output module 362 guide the subject 10's shooting posture and guide the subject 10's position movement to a predetermined position, such as at least one of the subject's 10's shooting operation, etc. Necessary guide messages can be output in video (eg, text) and audio respectively.

Each guide message output from the video output module 361 and the audio output module 362 may be already stored in the storage unit 34 .

Next, with reference to FIGS. 4A to 5 , the operation of the drinking state determination system having this structure will be described.

Referring to FIGS. 4A and 4B , the operation of the drinking state determination device 30 for determining whether the subject is a subject to be tested for alcohol consumption will be described.

First, when power required for operation is supplied and the operation of the drinking state determining device 30 starts (S10), the determination control unit 33 of the drinking state determining device 30 receives the subject identification information from the subject terminal 20. After that, it can be stored (S11).

For this purpose, the subject 10, as an example, generates a QR code in the subject terminal 20, which is his terminal, and then the QR code scanner located in the photographing unit 311 of the drinking state determination device 30 reads it. make it possible

At this time, the QR code may store an identification number (eg, a resident registration number or an alien registration number) for identifying the subject 10, and may additionally store nationality.

When the QR code output to the output unit 36 of the subject terminal 20 by the QR code scanner is read, the QR code scanner analyzes the read QR code and then extracts information stored in the QR code to determine the control unit 33 ) can be output.

Accordingly, the determination control unit 33 may store the information input from the QR code scanner in the storage unit 34 as subject identity information.

Next, the determination control unit 33 may confirm the identity of the target person 10 using the target person identification information transmitted from the target person terminal 20 (S12).

As already described, the database 35 stores worker identity information, which is identity information for all workers registered in the workplace.

Accordingly, the determination controller 33 may compare the operator identity information stored in the database 35 with the read subject identity information, and compare whether the read subject identity information is the same as one of the operator identity information (S13).

Therefore, when one of the worker identity information stored in the database 35 and the subject identity information are the same, the determination control unit 33 may determine the subject 10 as one of the workers currently registered.

By this operation, if it is determined that the target person 10 is not a worker currently registered in the database 35 (S13), the determination control unit 33 uses the data stored in the storage unit 34 to The target person 10 may output a guide message that is not a registered operator to the output unit 36 (S14). In this case, the determination controller 33 may output the corresponding guide message using at least one of text and voice using at least one of the video output module 361 and the audio output module 362 .

Due to this, if the target person 10 is a normal worker, it is possible to correct the wrong part by checking the registration procedure as a worker.

However, if the target person 10 is not a normal worker, the target person 10 may be restricted from entering the workplace by security guards or the like.

However, if the target person 10 is a normal worker already registered as a worker (S13), the determination control unit 33 determines whether the target person 10 is in a state in which he can normally perform his assigned task. can do.

Accordingly, the determination control unit 33 may control the operation of the photographing unit 311 to control the photographing operation of the target person 10 (S15).

For this reason, the photographing unit 311 may obtain subject image data, which is image data of the subject 10, by performing body imaging of the subject 10 according to the control signal applied from the determination control unit 33. .

At this time, when the location of the target person 10 is located in a place outside the shooting range, the shooting control unit for controlling the shooting operation of the shooting unit 311 stores the target person 10 so that it can be located at a predetermined shooting position ( A corresponding guide message stored in 34) may be output through the output unit 36. In this case, the corresponding guide message may be output using at least one of text and voice.

In this way, when the photographing operation of the target person 10 is completed by the photographing unit 311 , the photographing unit 311 may output the subject image data generated by the photographing operation to the determination controller 33 .

The determination control unit 33 may store the subject image data input from the photographing unit 311 in the storage unit 34 (S16).

The photographing operation by the photographing unit 311 may be performed at least once, and thus, the number of subject image data generated for each photographing operation may also be at least one.

For example, the subject image data generated by the photographing operation may be at least one of image data for a front of the face, image data for a front of the upper body, and image data for walking in a predetermined place.

In this way, when the photographing operation of the subject 10 is completed by the photographing unit 311 and the acquired subject image data is input, the determination controller 33 performs facial image data, which is image data related to a face among the subject image data. can be extracted (S17).

Next, the determination control unit 33 determines the operator's identity information (ie, the identity information of the operator having the same identity information as the subject's identity information) among the operator's face image data stored in the database 35. After selecting the face image data, the selected worker's face image data and the face image data extracted in step S17 may be compared with each other (S18).

Therefore, the determination controller 33 can determine whether the two faces are the same person because the similarity of the two face image data is equal to or greater than the set range, that is, the subject's face and the selected worker's face are the same ( S19).

When the two face image data are not face image data of the same person (S19), that is, when the target person 10 is not a worker having the determined worker identity information, the determination control unit 33 is stored in the storage unit 34 Using the data there is, the corresponding target person 10 may output a guide message that is not an identified operator as at least one of text and voice (S110).

In this way, it is determined whether the target person 10 is actually the corresponding worker by using not only the operation of checking the worker's identity information using the QR code but also the actual face image of the worker having the determined worker's identity information.

Due to this, in this example, since the accuracy and reliability of the identification of the target person 10 is greatly improved, it is possible to prevent a person who is not registered as a worker from entering the workplace as a normal worker using the exposed worker identity information. Thus, the safety of the workplace is guaranteed and security such as confidentiality can be maintained.

However, if it is determined that the two face image data are the face image data of the same person (S19), the determination controller 33 can finally confirm that the target person 10 is a normally registered worker (S111).

As such, in this example, since it is finally confirmed whether the worker is a normal worker using the face of the actual target person 10 as well as the worker identity information, the accuracy of the worker's authentication process is greatly increased.

However, in an alternative example, the operation of identifying the target person using face image data may be omitted. In this case, it is possible to determine whether or not the target person 10 is a registered worker by using the subject identification information using a QR code or the like.

When the corresponding target person 10 is determined to be a normal worker (S111), the determination control unit 33 determines the operator using the worker-related information stored in the database 35, the worker having the determined worker identity information (ie, the corresponding target person 10 )))), it is possible to read the assigned task and determine the corresponding task (S112).

Next, the determination controller 33 may obtain body information of the subject using image data acquired through the photographing operation performed in step S15 (S113).

As already described, the body information may be at least one of heart rate, skin color, and gait. In this example, necessary body information is acquired using acquired image data, but, on the other hand, necessary body information may be obtained by adding a separate device such as a heart rate monitor in addition to the photographing unit 311 such as a heart rate monitor.

Next, the determination controller 33 may determine whether at least one of the obtained heart rate, skin color, and gait has an abnormal state (S114).

In this case, the normal heart rate ranges may be set to be different from each other according to the age of the heart rate.

Therefore, the determination control unit 33 determines the age of the subject, reads the normal heart rate range from the storage unit 34, compares the obtained heart rate with the read normal heart rate range, and the obtained heart rate is included in the normal heart rate range. can determine whether

If the obtained heart rate is out of the read normal heart rate range, the determination controller 33 may classify the subject as a subject for the alcohol test.

Skin color is used to determine whether a drinking test is necessary by using a case in which a specific part, such as at least one of the face, neck, and ear, becomes red when in a drinking state.

Therefore, the color, which is the skin color of a specific part of the face, can be determined using the gradation value and distribution state of the specific part (eg, the face, neck, and ear) in the captured image data.

To this end, the determination control unit 33 may compare the gradation value and distribution state of a specific part (eg, face, neck, and ear) in the operator's face image data with the obtained skin color of the specific part.

Therefore, the determination controller 33 determines the operator's face image data for the corresponding worker (ie, the corresponding target person 10) in which the skin color of a specific part obtained from the subject image data of the subject 10 is stored in the database 35. In comparison, if the color of a specific part is red and widely distributed over a set size, the subject 10 may be classified as a subject for drinking.

In addition, since there is a case where the gait is not correct and staggers when drinking, it is possible to classify the subjects for the alcohol measurement using the gait.

Therefore, the determination control unit 33 compares the gait of the subject 10 obtained from the subject image data with the gait of the general public in the non-drinking state already stored in the storage 34 to determine the degree of shaking (eg, staggering). degree of shaking) is determined, and when the determined degree of shaking is greater than or equal to the set shaking degree, the subject 10 may be classified as a subject for a drinking test.

In this way, if there is abnormal body information among the acquired body information, the determination controller 33 may determine the target person 10 as a drinking test subject (S115).

However, if the current subject 10 is not classified as a subject for a breathalyzer test using body information (S114), the determination control unit 33 determines whether the current task in charge is a risky task for determining whether a breathalyzer test is required or not. can

Accordingly, the determination controller 33 may compare the determined current task and whether or not a breathalyzer measurement is required according to the type of task described in the task-related information, and determine whether the current task requires a breathalyzer test (S116).

If the determined current job is a job requiring a sobriety test (S116), the determination control unit may classify the subject as a sobriety test subject (S117).

However, if the determined current task is not a task requiring alcohol measurement (S116), the determination control unit 33 uses the worker-related information of the subject 10 to determine whether the subject 10 has drinking-related information. That is, it is possible to determine whether the subject 10 has a drinking accident history or a history of alcoholism treatment (S118).

If it is determined that the target person 10 has drinking-related information (S118), the determination control unit 33 may classify the target person 10 as a drinking measurement target (S119).

As such, the determination control unit 33 may determine whether the subject 10 is a subject to be tested for alcohol consumption by using at least one of the subject's body information, current task, and drinking-related information. As a result, since the worker who is administered to the workplace is prevented from performing work while intoxicated, the risk of safety accidents and concerns about poor construction caused by drinking can be greatly reduced or eliminated.

In this way, when the subject is classified as a subject for a sobriety test (S115, S117, S119), the determination control unit 33 uses the output unit 36 to perform the corresponding task immediately as a subject for a sobriety test. It is possible to request a sobriety measurement using the sobriety measurement unit 312 to the target person 10 by outputting a message indicating that a sobriety measurement is not required by at least one of voice and text messages (S120).

Accordingly, a subject classified as a drinking test subject may perform a drinking test using the alcohol measuring unit 312 .

However, in step S118, when there is no drinking-related information about the target person 10, the determination controller 33 may determine that the target person 10 has no drinking-related problem. Therefore, the determination control unit 33 classifies the subject 10 as a normal subject who does not need a separate alcohol measurement (S121), and then the subject 10 viewed through the output unit 36 is a normal subject without alcohol measurement. It is possible to output a message prompting immediate input into the corresponding task (S122).

By the operation of the determination control unit 33, the worker who is put into the workplace is determined whether or not to measure alcohol consumption according to his or her physical condition, work risk, or drinking-related information, so it is better to perform high-risk work while intoxicated. may be blocked.

Next, with reference to FIG. 5 , the operation of the drinking state determination device 30 that performs the alcohol measurement control operation for the drinking test subject will be described.

The target person 10 classified as a drinking test subject may perform a drinking test using the breathalyzer 312 . In this case, the subject to be tested for alcohol consumption may perform the alcohol measurement after inputting the subject's identity information such as his or her identification number using the user input unit 32 or the like before the alcohol measurement.

Therefore, the determination control unit 33 may read the input subject identification information and store it in the storage unit 34 (S21).

In addition, the breathalyzer 312 may generate a corresponding breathalyzer measurement value when the alcohol measurement of the alcohol test subject is completed, and then output the generated breathalyzer measurement value to the determination control unit 33 through wireless or wired communication. there is.

Accordingly, when the drinking measurement value is input from the drinking measurement unit 312, the determination controller 33 may read the drinking measurement value and store it in the storage unit 34 corresponding to the input subject identification information (S22).

In this way, when the subject identity information and the breathalyzer measurement value of the subject who performed the breathalyzer test are stored, the determination control unit 33 uses the subject identity information to determine the type and task of the corresponding worker, that is, the breathalyzer test subject. It is possible to determine the degree of risk (S23).

Then, the determination control unit may determine a permissible drinking level according to the determined type of work and the degree of risk of the work (S24).

Since the allowable drinking level may be determined differently according to the type of work or the risk of the work, each subject may have a different allowable drinking level.

For example, if the type of work is high-speed work or firearms handling work, the same permissible drinking level may be applied regardless of the risk level of the work in charge.

However, in the case of high-speed work, different permissible drinking levels may be applied depending on the degree of risk.

In addition, when the type of work is a simple chore, different allowable drinking levels may be applied depending on the degree of risk.

In this way, when the allowable drinking level according to the type of work and at least one degree of risk is determined, the determination control unit 33 may compare the measured drinking level with the allowable drinking level for the target person 10 (S25).

If the drinking measurement value is less than the allowable drinking value (S25), the determination control unit 33 may determine that the target person 10 is in a state in which the task in charge is possible (S26).

Accordingly, the determination control unit 33 may output an operation availability message through at least one of the video output module 361 and the audio output module 362 of the output unit 36 (S27).

However, if the drinking measurement value exceeds the allowable drinking value (S25), the determination control unit 33 may determine that the current drinking level of the target person 10 cannot safely perform the task in charge (S28).

Accordingly, the determination control unit 33 may output an operation disable message through at least one of the video output module 361 and the audio output module 362 of the output unit 36 (S29).

In this way, since the alcohol measurement is actually performed on the subject 10 classified as a drinking test subject, it is possible to determine whether the drinking test subject is actually in a current drinking state, and accordingly, whether or not to perform the task in charge can be determined.

Therefore, the risk of accidents that may occur when performing work in a drunken state can be greatly reduced.
