The figure which shows the example of the screen S1 displayed on the monitor 280. FIG.

  FIG. 1 shows an outline of an entrance / exit management system 200. The entrance / exit management system 200 includes a monitor 280 and a tablet terminal 290. The entrance / exit management system 200 is installed at a site having an entrance / exit 801 and a passage 802. The worker 990 enters and exits from the entrance / exit 801 through the passage 802 to the work site (a management area in which only workers are allowed to enter) and exit from the site.

  The monitor 280 is a display device such as a liquid crystal display, and is connected to the tablet terminal 290. It is preferable that the monitor 280 is set at a position where the worker 990 can easily see when entering. The tablet terminal 290 is a computer terminal that incorporates a camera 291 and includes at least an imaging function. The camera 291 is adjusted in shooting conditions such as position, orientation, and focus so that only one side of the helmet 900 worn by the worker 990 passing through the entrance / exit 801 enters the imaging range. For example, as shown in the figure, the worker 990 enters while looking at the tablet terminal 290 slightly diagonally to the right, and the right side of the helmet 900 is included in the imaging range, but the left side is not included in the imaging range. Adjusted to. Conversely, when the worker 990 leaves, the left side enters the imaging range and the right side does not enter the imaging range. That is, only one of the seals 110 is always photographed according to the traveling direction of the worker 990.

  FIG. 2 shows a helmet 900 that each worker 990 wears for his own use. The helmet 900 is required to be worn when entering the management area. As shown to (a), the seal | sticker 110 (110R, 110L) is affixed on the left side surface and the right side surface of the helmet 900, respectively. The seal 110 is a sheet-like member, and the color code 120 is formed on the surface thereof by printing or the like. The color code 120 is composed of a plurality of blocks 121. Each block 121 is formed of any one of three colors (or seven colors). This combination of color schemes differs for each seal 110. In other words, the seal 110R and the seal 110L do not have the same code pattern. The helmets 900 worn by the respective workers 990 are affixed with two sets of the seal 110R and the seal 110L, but the color pattern of these seals is different for each worker. Thus, by assigning color codes 120 having different contents for each worker, each worker can be uniquely identified based on the code.

FIG. 3 shows functions of the entrance / exit management system 200. The entrance / exit management system 200 includes an imaging unit 202, a timing unit 208, a storage unit 206, an input unit 207, a display unit 204, and a control unit 209.
The imaging unit 202 is a camera having an optical system such as a lens and an imaging device, and always captures a preset range (a space around the entrance / exit 801), and the obtained image data is sent to the control unit 209. Output.
The display unit 204 is realized by a liquid crystal panel or a drive circuit, and displays an image when receiving a video signal from the control unit 209. In this example, the display unit 204 is implemented as a display screen of the monitor 280 and a display screen of the tablet terminal 290. In one aspect, the same content is displayed on both screens. However, one of the display screens may not be functioned. Alternatively, one content may be displayed in cooperation with the two screens of the monitor 280 and the tablet terminal 290.

  The input unit 207 is an input device such as a keyboard and a mouse, and is used for inputting information to be registered in the storage unit 206. The storage unit 206 is a hard disk or a semiconductor memory, and stores a worker management table T1, an entrance / exit management table T2, and a personal history table T3. The clock unit 208 is a computer built-in clock and counts time.

FIG. 4 shows an example of information stored in the worker management table T1. The worker management table T1 stores a name, attribute information, and a set of code patterns in association with the ID.
The ID is a number that uniquely identifies the worker. The attribute information is information relating to the worker's identity, and includes information for identifying the corporation to which the worker belongs (including the case of a self-employed company that does not have a corporation).

The code pattern is a value obtained by encoding a color arrangement pattern of the color code 120 specified by the image recognition process using a predetermined algorithm. A color arrangement pattern of one color code corresponds to one code pattern value. “Left” and “right” are information indicating whether the seal 110 having the code pattern is attached to either the left side surface or the right side surface of the helmet 900. As described above, since the two seals 110 (that is, 110L and 110R) are always affixed to the helmet 900, a total of two code patterns are always associated with one ID.
Referring to FIG. 4, if one code is known, the wearer of the helmet to which the code is attached and whether the code is attached to the left or right side are specified. For example, “10001101011” is affixed to the left side of the helmet of the worker identified by ID “01359”, and the name of the worker is △△ Saburo, and it is specified that he is working for ABC construction. The

  FIG. 5 shows an example of information stored in the entrance / exit management table T2. In the entrance / exit management table T2, the presence / absence of entry / exit and the time thereof are stored for every worker to be managed on that day. In the example of the figure, on June 6, 2014, the worker with ID “01359” has confirmed entry but has not confirmed leaving (ie, estimated to be staying in the management area) ). The worker with ID “09570” has entered but has already exited, and the worker with ID “02580” has not entered or exited to date.

  FIG. 6 shows an example of information stored in the personal history table T3. The personal history table T3 records the entry / exit date and time for this management area for each ID. In the figure, only the record of the worker specified by the ID “01548” is shown. Such records are stored in the personal history table T3 for all workers to be managed.

  The control unit 209 is realized by various processors such as a CPU and a memory such as a RAM. The control unit 209 controls the imaging unit 202, the display unit 204, the input unit 207, and the time measuring unit 208. The control unit 209 includes a determination unit 201. The determination unit 201 is realized by an image processing processor or the like, and determines one management target and whether the one management target has entered or left the management area based on the captured identification image. Specifically, the determination unit 201 receives imaging data from the sequential imaging unit 202, performs image analysis, and monitors whether the image representing the color code 120 is included in the captured image. When an image representing the color code 120 is detected, the determination unit 201 identifies the code pattern using a predetermined algorithm. When a plurality of images representing the color code 120 are extracted from one image (typically, when two or more workers 990 approach and pass through the vicinity of the entrance / exit 801), a plurality of detected images are detected. The code pattern is specified for all the images.

Subsequently, the determination unit 201 refers to the worker management table T1, identifies the ID (corresponding to the code pattern) and the position (left or right) where the color code 120 is affixed, and the identified position. Based on the above, the traveling direction of the worker 990 is determined. For example, in the case where the arrangement relationship of the camera 291 with respect to the entrance / exit 801 is as shown in FIG. 1, if the code formed on the seal 110R attached to the right side surface is detected, the entrance is determined. If the code formed on the left side seal 110L is detected, it is determined to leave.
When determining whether to enter / exit, the control unit 209 updates the contents of the entrance / exit management table T2 and the personal history table T3 together with the current time.

FIG. 7 shows an example of a screen S1 displayed on the monitor 280. The screen S1 includes an area A1, an area A2, an area A3, and an area A4. The captured image is displayed in the area A1.
In the area A2, information on the entry / exit status of all the workers 990 registered today is displayed based on the latest registration contents of the entry / exit management table T2. Specifically, a rectangular object C displaying a name is displayed corresponding to each registered worker, and each object corresponds to one of three states of entering, leaving, or not entering. Colored in different colors. Workers can check other workers by looking at this screen when entering and leaving.
In the area A4, the current time is displayed. In the area A3, a message corresponding to the identified worker and the determined entry / exit is displayed. Thereby, the worker confirms that his / her entrance / exit is grasped by the entrance / exit management system 200. In the area A3, attribute information may be read from the worker management table T1 and displayed.

  According to the above-described embodiment, in order to register the entry / exit of the worker separately, the color code issued for each user is attached to the helmet by printing on a sticker sheet without providing a wireless communication function. The system can be constructed and operated at low cost. In particular, even if the number of workers to be monitored increases, a new code can be issued and registered and attached to the helmet used by the worker, so that it can be dealt with inexpensively and immediately. On the other hand, since the worker does not need to perform operations such as operating the terminal to register entry / exit, it is only necessary to wear a helmet with a sticker 110 and pass through the entrance / exit. There is no burden.

The attachment positions of the seals 110R and 110L are not limited to the side surfaces of the helmet 900. For example, as shown in FIG. 8, both sheets may be attached near the top of the head. In this case, the camera 291 is adjusted so that at least the vicinity of the top of the head is included in the imaging range. That is, as shown in FIG. 9, the captured images F1 and F2 always include two stickers 110.
The determination unit 201 determines whether the entry is to the management area or the exit from the management area based on the positional relationship between the two captured images. Specifically, as shown in FIG. 9A, when the seal 110L is positioned on the left side with respect to the seal 110R, the traveling direction of 990 is a direction from the bottom to the top of the page. Once the top and bottom of the image and the direction of the entrance / exit port 801 for the video are registered once, it is possible to determine whether this traveling direction corresponds to when entering or leaving. For example, if there is an entrance / exit 801 above the page, it is determined to be an entrance. On the contrary, when the positional relationship between the seals 110L and 110R is as shown in FIG.

  As shown in FIG. 10, only one seal 110 may be attached to the helmet 900. In this case, the determination unit 201 determines whether to enter the management area or to leave the management area based on a plurality of images obtained by imaging one worker at different timings. Specifically, for example, it is assumed that 30 frames are continuously shot per second, and two of the images are as shown in FIG. An image taken earlier in time is F3, and an image taken later in time is F4. It can be seen that the position of 110 in the image changes as the worker 990 moves. This means that the worker 990 has moved from the bottom of the screen to the top as time passes. If the direction of the top and bottom of the image and the direction of the entrance / exit 801 of the video are registered in advance, it is possible to determine whether the operation 990 in the traveling direction is when entering or leaving.

  A gate device that restricts entry into or exit from the management area may be provided in the entrance / exit management system 200, and the gate device may be controlled based on the read color code 120. For example, the gate is closed to prevent entry unless it is determined that the worker 990 is registered by reading the color code 120. In addition, when the code attribute information does not satisfy a predetermined condition, the gate may be controlled to be closed.

  Instead of displaying the entrance / exit status of all the workers 990 to be managed, the entrance / exit status of only some workers may be displayed. For example, the display contents are changed according to the attribute information of the worker. For example, the entry / exit status of all employees is displayed for a given company (such as a construction management company), and only workers who have specific attributes are displayed for other persons (such as employees of secondary contractors). Do not display the status of workers other than yourself. Thus, by providing different information depending on workers, it is possible to share information necessary for work among workers while considering management of personal information.

The above-described embodiment is an example of an image and a form for identifying each worker, a pasting position of the image, and a camera position. An image may be formed on a part of work clothes or skin (body) instead of a helmet. For example, a card on which a color code 120 that can identify an individual is printed is issued to a worker who does not own a helmet dedicated to the user. Then, this worker may be urged to carry the card before entering the management area and hold it in the direction of the camera 291 at the entrance / exit 801. This card is issued as a set of two for entrance and exit for one person, and a different color code is printed on each. Alternatively, the two color codes may be formed on both sides of a single card. Alternatively, when only one color code is given to one person, as shown in FIG. 11, it is possible to determine whether to enter / exit by image analysis.
In short, in the present technology, it is only necessary that an image that can move with the worker 990 and identify each worker passes through a space that can be detected by the imaging unit. For example, if normal reading cannot be performed due to the position where the identification code is applied, the posture of the worker, etc., the imaging means (imaging range) and the color code are stopped or placed in front of the camera so as to have a predetermined positional relationship. The worker 990 may be prompted to take an action such as holding a code.

  The target for detecting entry / exit into the management area may be other than human. For example, when an article (luggage or cargo) is moved into or out of a management area by a conveyor or a vehicle via the entrance / exit 801, at least one seal 110 is pasted on the vehicle carrying the article or article. Thus, the identification of the article and the determination of the moving direction (entrance / exit) may be performed.

  An internal area of a vehicle that moves with a person to be managed as a management area may be defined as a management area, and an imaging unit may be provided in the vehicle at a position for imaging a person passing through the entrance. A specific example is as follows. The vehicle is, for example, a transportation ship. This transport ship is used to transfer workers between the pier and the work place at sea. Further, when there are a plurality of work places, it is also used for movement of workers between work places. A tablet terminal 290 is provided at the entrance of the transportation ship. Shooting conditions such as position, orientation, and focus of the tablet terminal 290 are adjusted so that only one side of the helmet 900 worn by the worker 990 who passes through the entrance / exit is within the imaging range. The determination unit 201 of the entrance / exit management system 200 determines whether the worker is on board / disembarks by the same method as the entrance / exit determination in the above embodiment. The storage unit 206 stores an entrance / exit management table T2A and a work place database D1. In addition to the camera 291, the tablet terminal 290 has a function of acquiring position information of the tablet terminal 290 using a satellite navigation system or the like.

FIG. 12 is a diagram illustrating an example of a work place at sea. As an example of dredging work, the marine work places are, for example, a grab ship 701, a pump ship 702, a surveying dredge 703, an offshore breakwater 704, and the like. Grab ship 701 and pump ship 702 are examples in which the work place is a moving body. At the pier 705 and these work places, there is provided a communication device 600 that performs communication via a wireless local area network (LAN) in an ad hoc mode (a mode in which devices directly communicate with each other without using an access point). The tablet terminal 290 provided in the transportation ship 300 has a communication function for communicating with the communication device 600 via the wireless LAN in the ad hoc mode only when the distance from the communication device 600 is within a predetermined range. . That is, the tablet terminal 290 receives radio waves transmitted from the communication device 600 when the distance from the communication device 600 is within a predetermined range (for example, several meters to several tens of meters). This predetermined value is larger than the distance that the traffic ship 300 needs to approach at least the work place in order to disembark an occupant to the work place or board the work place, and the transport ship 300 is in the work place. Is set smaller than the approaching distance when passing through. In other words, the predetermined value is set so that an estimation that the fact that the tablet terminal 290 has received the wireless ID means that the boarding or disembarking of the work place has been performed is reasonable. For example, the distance from the boarding port (unloading port) position of the transportation ship 300 provided at the work place to the communication device 600, or the position closest to the work place on the route of the transportation ship 300 when passing through the work place. The intensity of the transmission radio wave of communication device 600 is set according to the above.
When the determination unit 201 determines whether the worker enters or leaves, the tablet terminal 290 receives the ID from the communication device 600. In other words, the communication function of the tablet terminal 290 is a receiving means provided on the vehicle, and is provided in the work place that is the occupant's transportation place or boarding place when the determination means determines the person's entry / exit. It is an example of the receiving means which receives the information for identifying the said communication apparatus from a communication apparatus. The communication method between the tablet terminal 290 and the communication device 600 may be RFID (radio frequency identifier).

FIG. 13 is a diagram showing the work place database D1. In the work place database D1, the ID of the communication device 600 and the name of the work place are recorded in association with each work place.
FIG. 14 is a diagram showing the entrance / exit management table T2A. In the entrance / exit management table T2A, the worker ID, state, date / time, position information, and work place name are recorded. The worker ID is an ID identified from the code pattern. The state is one of boarding / disembarking determined by the determination unit 201. The date and time is the date and time when boarding / disembarking was determined. The position information is position information acquired by the tablet terminal 290 using a satellite navigation system or the like. The name of the work place is specified by the tablet terminal 290 reading the work place name corresponding to the ID received from the communication device 600 via the wireless LAN from the work place database D1. This configuration is an example of a specifying unit that specifies a work place based on the received ID. Similar to the above-described personal history table T3, the history of boarding / disembarking may be recorded for each worker.

According to this configuration, since the boarding corresponds to exit from the work place and the disembarkation corresponds to entry into the work place, the worker can enter and leave the work place without providing the tablet terminal 290 at the work place. Can be determined.
Further, even when the work place can move, such as a grab ship 701 or a pump ship 702, the work place where the worker entered or exited can be specified based on the ID received via the wireless LAN. .
You may identify a work place from the positional information acquired using the satellite navigation system. However, when two work places are close to each other as in the grab ship 701 and the pump ship 702, there is a possibility that the work place that has entered and exited may be erroneously determined in the determination based on the position information by the satellite navigation system. On the other hand, in the determination based on the ID received via the wireless LAN, it is possible to prevent the erroneous determination of the work place that has entered and exited by specifying the work place from the ID of the communication device 600 having the maximum reception strength. .

  In the above configuration, the vehicle may be a bus, a train, an aircraft, or the like. Moreover, you may apply this invention to another use. For example, the present invention may be applied to sightseeing buses, ships, trains, etc. to determine whether a group tourist is getting on or off. Alternatively, the present invention may be applied to a school bus, a school bus, etc. to determine whether a child or a student gets on or off.

  FIG. 15 is a diagram illustrating a modification of the medium forming the color code 120. FIG. 15A shows an example in which the color code 120 is formed on the ribbon 130, and a safety pin 131 is provided on the ribbon 130. FIG. 15B is an example in which the color code 120 is formed on the badge 140, and a safety pin (not shown) is provided on the back side of the surface on which the color code 120 is formed. Ribbon 130 or badge 140 is worn near the shoulder of the sleeve of the garment. Although the ribbon 130 and the badge 140 of different color codes 120 may be attached to the left and right sleeves as in the above embodiment, the two tablet terminals so that both sleeves of the person passing through the entrance / exit are within the imaging range. 290 may be provided, and only one ribbon 130 or badge 140 may be attached to one sleeve, and boarding / alighting may be determined from the moving direction of the color code 120 that has been imaged. In addition, when a child or a student wears a uniform hat, the ribbon 130 or the badge 140 may be attached to the hat.

  It is not desirable to require group tourists to wear helmets or hats as alternatives from the viewpoint of tourists' mental burden and cost. On the other hand, the ribbon 130 and the badge 140 are less burdensome for tourists and less expensive. Further, since the hat is generally made of cloth, the seal 110 is easily peeled off, but since the ribbon 130 and the badge 140 are attached with a safety pin or the like, they are not easily detached from the hat. Even if there is no uniform hat, it is only necessary to attach the ribbon 130 or the badge 140 to the sleeve of the clothes, so that it is not necessary to procure a new hat.

  In the method for implementing the functions of the entrance / exit management system 200 in hardware, the configuration of the above embodiment is merely an example. For example, storage devices that store the worker management table T1 to the personal history table T3 may be installed in different computers connected to the entrance / exit management system 200 via a network.

  In short, the entrance / exit management system according to the present invention is installed in a place that leads to a management area, and an imaging unit that captures an identification image provided at a predetermined location in each of a plurality of management objects to be moved, and the imaging unit Based on the identification image picked up in this way, it is discriminated by the discriminating means and the discriminating means for discriminating whether the one management object has entered the management area or exited from the management area. It is only necessary to have display means for displaying the entrance / exit status.

In a preferred embodiment, the entrance / exit management system according to the present invention may further have a system function for managing the status and behavior of 990 other than entrance / exit.
FIG. 16 shows an overview of a management system 400 having a function of the entrance / exit management system and a function of managing the water supply state of the worker 990.
The management system 400 includes an entrance / exit management system 200A, a water supply management device 310, a water server 320, a receiver 321 and a wireless tag 340. The water supply management device 310 is connected to the entrance / exit management system 200 </ b> A via the communication network 390. The communication network 390 is, for example, the Internet. The water supply management device 310 is connected to each water server 320 (320-1, 320-2, 320-3) via the communication network 330. The communication network 330 is a wired LAN, for example.

  The water server 320 (320-1, 320-2, 320-3) includes a tank for storing drinking water and other drinks and an operation lever, and is a general water supply (water) that can be used when the worker 990 needs it. Server). For example, one water server 320 is installed for each predetermined section in the management area managed by the entrance / exit management system 200A. In this case, the worker 990 uses the water server 320 while entering. Alternatively, the water server 320 may be provided outside the management area. In this case, the worker 990 uses the water server 320 before or after entering.

The wireless tag 340 is a wireless transmitter that performs short-range wireless communication according to Bluetooth (registered trademark) or the like. Specifically, the reach of the radio wave transmitted from the wireless tag 340 is set in advance, for example, 50 cm. In addition, a user ID for uniquely identifying each worker 990 is written in an element constituting the wireless tag 340, and a signal including the user ID is intermittently transmitted.
The wireless tag 340 is attached to clothes, a hat, and other carry-on items worn by the worker 990, and changes its position following the movement of the worker 990.

The receiver 321 is a receiver that is provided for each water server 320 and can receive radio waves from the wireless tag 340. Specifically, each receiver 321 receives a radio wave transmitted from the wireless tag 340 when the distance from the wireless tag 340 is equal to or less than a preset distance.
The receiver 321 is built in the water server 320 or attached to the housing of the water server 320. Alternatively, the receiver 321 is provided in the vicinity of the water server 320 (for example, within a predetermined range (for example, a circle with a radius of several tens of centimeters) with the water server 320 as a reference. Rather than passing near the server 320, it is set so that the estimation that the water server 320 is approached for the purpose of water supply is reasonably satisfied.
Each water server 320 is set with a unique device ID. The wireless tag 340 transmits the received user ID and device ID to the water supply management device 310.
The number of water servers 320 (and receivers 321) in the figure is merely an example and is arbitrary.

  The water supply management device 310 is a computer device that includes a communication interface for communicating with the water server 320 and the entrance / exit management system 200A, an input unit, a display unit, and a storage unit (all not shown).

Upon receiving the user ID and the device ID from the receiver 321, the water supply management device 310 generates and stores a record in which the user ID, the device ID, and the received time are associated with each other. Specifically, the user ID and water supply information (the identifier of the water server 320 that has supplied water and the time at which the water was supplied) are stored in association with each other.
That is, each time the worker 990 approaches the receiver 321, one record is generated in the water supply management device 310, and the fact of the approach is stored. The fact that the worker 990 has approached the receiver 321 means that the worker 990 has approached the water server 320. This indirectly indicates that the worker 990 has replenished water using the water server 320. That is, a record is generated every time the worker 990 performs water replenishment using the water server 320.

  In order to more reliably determine that hydration has been performed, for example, the water supply management device 310 measures the time of approaching one water server 320 of a certain worker 990, and the measured time is predetermined. You may determine with the hydration having been performed when it is more than a period.

  The water supply information is transmitted to the entrance / exit management system 200A. The water supply information may be transmitted every time it is received, or may be transmitted in response to a request from the entrance / exit management system 200A, or a record stored within that time is read at every predetermined time. You may send it.

  FIG. 17 shows the functions of the entrance / exit management system 200A. The entrance / exit management system 200A differs from the entrance / exit management system 200 in that an information acquisition unit 210 that acquires information on the behavior and state of the worker 990 other than the entrance / exit is provided, and through the information acquisition unit 210. It is the point which processes the acquired water supply information. The information acquisition unit 210 is a communication interface for communicating with the water supply management device 310, and acquires water supply information from the water supply management device 310. The control unit 209 updates the information stored in the storage unit 206 based on the water supply information.

FIG. 18A shows an example of information in the personal history table T3B stored in the storage unit 206. FIG. In the personal history table T3B, in addition to the information stored in the personal history table T3, information indicating whether water has been supplied using the water server 320 for each user and for each day is stored. In the drawing, the worker 990 of “01548” means that it has been determined that the water server 320-1 has supplied water at 11:00 am.
FIG. 18B shows an example of information in the entrance / exit management table T2B stored in the storage unit 206. In the entrance / exit management table T2B, in addition to the information stored in the entrance / exit management table T2, information indicating the water supply status of each worker 990 is stored. This information is generated based on the water supply information stored in the personal history table T3B. This information may be the same information as the personal history table T3B, or the control unit 209 determines whether the water supply state is appropriate based on the water supply time and frequency based on a predetermined algorithm. It may be information indicating the result.

Information about the water supply state stored in the entrance / exit management table T2B is read from the storage unit 206 and displayed on the display unit 204 when the worker 990 enters or leaves.
FIG. 19 is a diagram showing an example of a screen S1 displayed on the monitor 280. This example is read when leaving, and a message generated by the control unit 209 corresponding to the water supply information is displayed in the area A3 in the screen S1.

  In the management system 400, information related to water supply and information related to entrance / exit can be centrally managed. As described above, by managing the health of the worker 990 from the viewpoint of water supply, it is expected that the safety or productivity of the work in the management area is improved.

  In addition, you may provide the function of the water supply management apparatus 310 in the entrance / exit management system 200A, without providing the water supply management apparatus 310. FIG. In this case, each water server 320 communicates directly with the entrance / exit management system 200. That is, in addition to the entrance / exit management function, 300 is based on the wireless reception means provided in the water server 320 (or in the vicinity of the water server 320) and the signal received by the wireless reception means from the wireless transmission means. Water supply management means for determining whether or not the person has supplied water with the water supply device, water supply information acquisition means for acquiring the determination result, and water supply for the person based on the acquired determination result Although the display means for displaying information representing the situation is provided, it does not matter which apparatus is equipped with these means.

FIG. 20 shows an overview of a management system 500 having an entrance / exit management function and an alcohol detection function.
The management system 500 includes an entrance / exit management system 200B and an alcohol detection device 510.
The alcohol detection device 510 is preferably provided on the near side of the entrance / exit near the position where the monitor 280 is provided, and is connected to the entrance / exit management system 200B by a cable or the like. In this case, the worker 990 is first inspected by the management system 500. The monitor 280 may first display a message that prompts the management system 500 to undergo an inspection when entering.

The alcohol detection device 510 includes a communication unit 501, an alcohol detection unit 502, and a user specifying unit 503.
The alcohol detection unit 502 detects the concentration of alcohol in the body of the subject. Specifically, the alcohol detection unit 502 includes a sensor that measures the concentration of alcohol contained in the exhalation of the worker 990. This sensor may be of any measurement method such as a semiconductor type, catalytic combustion type, or fuel electronic type. In addition, the alcohol detection unit 502 includes a processor that determines whether the alcohol concentration is equal to or higher than a reference value based on the measurement value.
The user specifying unit 503 is an input device such as a keyboard, a mouse, or a touch panel, and receives an input of a user ID of a worker 990 who is a subject. Alternatively, if an imaging device is provided instead of the input device and the subject wears the helmet 900 with the above-described seal 110, the user ID may be determined from the video.
The communication unit 501 outputs the determination result generated by the alcohol detection unit 502 to the entrance / exit management system 200B in association with the user ID.

The entrance / exit management system 200B is different from the entrance / exit management system 200A in that the information to be processed in the control unit 209 is not water supply information but information indicating a result of alcohol determination.
Specifically, when the information acquisition unit 210 acquires the determination result, the control unit 209 generates a message corresponding to the determination result and outputs the message to the display unit 204.

  FIG. 21 shows an example of a screen S1 displayed on the monitor 280. In the figure, a message notifying that alcohol having a concentration higher than the reference is detected is displayed in the area A3. Alternatively, the entrance / exit management system 200B may be provided with a sound emission mechanism to emit a warning sound to warn a user whose alcohol has been detected.

  The determination result may be stored in the entrance / exit management table T2 or the personal history table T3 in the storage unit 206. In this case, the content of the message to be generated may be varied depending on the number of times alcohol is detected and the concentration.

  Further, the storage unit 206 may be connected to a gate opening / closing device (not shown), and a signal for controlling the gate opening / closing may be output to the gate opening / closing device according to the determination result. Thereby, the drunk worker 990 can be prevented from entering the management area. As a result, the risk of an accident being caused by the worker 990 whose judgment power has been reduced is reduced.
