The article take-out determination means determines whether or not the article can be taken out based on the information acquired by the third information acquisition means. The article take-out determination means specifies a use period of the article to be taken out from the second registration information, and a date and time when the article has passed through the entrance / exit gate is within the use period of the article and is outside the working time zone. Is permitted to take out the article.

  In this way, it is allowed to take out the articles used in the construction work for maintenance, but it is possible to restrict other articles to be taken out. Therefore, even if a third party enters by an unauthorized method, it is possible to reduce the possibility that an article is taken out by an unauthorized intruder.

The entrance / exit gate may be provided with a video recording means for recording the entrance or the exit who takes out the article.
If the entrance determination means does not permit entry, or if the article removal determination means does not permit removal, an alarm is issued at the entrance / exit gate and recorded by the construction manager in the video recording means. The video information is preferably sent by e-mail.

  According to the present invention, in addition to the above-described effects, by issuing an alarm at an entrance / exit gate to an unauthorized intruder in the construction area or an unauthorized person taking out an article from within the construction area, the illegal operation is performed. It is possible to warn unintentional visitors and stop or deter illegal intrusion and illegal shoplifting. In addition, by recording an unauthorized intruder or an illegally exited person as video information, it is possible to quickly respond to the unauthorized intruder.

  According to the present invention, it is possible to reduce the possibility that a third party enters the construction work area in an unauthorized manner.

In addition, the visitor information reading means 3 may read the information of the entrance card P again when the visitor leaves (that is, the exiting person).

  The head information obtaining means 4 obtains information used for determining whether or not a visitor wears a helmet. Construction personnel who enter the construction work area 1 are required to wear a helmet for safety. The head information obtaining means 4 is, for example, a visible light camera or a thermo camera using infrared rays. The head information acquisition means 4 captures an image of the vicinity of the visitor's head using visible light in the former case, and detects infrared radiation energy radiated from the visitor in the latter case, Obtain temperature information around the part. Then, the head information acquisition unit 4 transmits the acquired image and temperature information of the vicinity of the head of the visitor to the entrance / exit management device 10. The head information obtaining means 4 is installed in a place where the vicinity of the head of the visitor can be easily photographed, and is installed above the entrance gate 2 here. The head information obtaining means 4 may be installed on one or both of the gate columns 2a and 2b constituting the entrance gate 2.

The tool information reading means 5 acquires information stored in a tool tag Q attached to a tool possessed by the exiting person. The tool tag Q is a so-called RF tag, and includes a storage unit that stores information, a transmission unit that reads information stored in the storage unit and transmits the information. The tool tag Q is attached to a tool used in construction work. In the tool tag Q, information used for determining whether or not the tool can be taken out of the construction work area 1 (for example, an ID for identifying the tool and information on the use of the tool) is stored. Note that the tool tag Q is an example of a second recording medium. In order to make it difficult for the tool tag Q to be detached from the tool, the tool tag Q may be embedded in the tool and installed.

The alarm means 6 informs a person around the entrance / exit gate 2 that an entry not permitted by the entrance has been entered and that a tool not permitted to be taken out has been taken out. The warning means 6 is preferably installed near the entrance / exit gate 2 (entrance / exit gate). It is preferable that the alarm unit 6 informs a person around the entrance / exit gate 2 via a visual angle or hearing that there has been unauthorized entry or unauthorized removal. The warning means 6 is, for example, a rotating light or a buzzer.
The image recording means 7 is for recording an image of an entrance / exit person passing through the entrance / exit gate 2. The image recording means 7 is, for example, a dome-type security camera whose camera is covered with a dome-shaped translucent case.

The entrance / exit management device 10 is, for example, a PC (Personal Computer), and is operated by an administrator of the entrance / exit management system 100. The entrance / exit management device 10 is communicably connected to other components constituting the entrance / exit management system 100. The entrance / exit management device 10 includes a storage unit 11 and a control unit 12, as shown in FIG.
The storage unit 11 includes a storage medium such as a hard disk drive (HDD), a random access memory (RAM), a read only memory (ROM), and a flash memory. The control unit 12 is realized by a program execution process by a CPU (Central Processing Unit), a dedicated circuit, or the like. When the control unit 12 is realized by a program execution process, the storage unit 11 stores a program for realizing the function of the control unit 12.

As shown in FIG. 2, the storage unit 11 includes a construction-related person DB 11a, a tool DB 11b, and an entrance / exit image DB 11c. The storage unit 11 may have, for example, information on a schedule of construction work in addition to the above information. In addition, a part of the information stored in the storage unit 11 is stored in a device other than the entrance / exit management device 10 (for example, an external server), or in an entrance card P or a tool tag Q, and the entrance / exit management device 10 may be operated as necessary. That information may be obtained.
The construction-related person DB 11a stores information related to the construction-related person, and particularly stores information indicating whether or not entry is permitted in association with information for identifying the construction-related person or affiliation. FIG. 3A shows a data configuration example of the construction-related person DB 11a.
The construction-related person DB 11a here includes a construction-related person ID, affiliation information, admission information, and entry / exit categories. The construction-related person ID is information for identifying a construction-related person. The affiliation information is information indicating the affiliation of the construction-related person (for example, a company, a department, a group, etc.). The entry permission information is information indicating whether entry into the construction work area 1 is permitted. The entry availability information may correspond to, for example, a work process, and register whether or not to permit entry to the construction work area 1 for each work process. The entry / exit category is information indicating whether or not a construction worker has entered the construction work area 1.
The tool DB 11b stores information indicating the necessity of using a tool in a work process and a work time zone. FIG. 3B shows a data configuration example of the tool DB 11b.
The tool DB 11b here includes a tool ID and tool use information. The tool ID is information for identifying a tool. The tool ID may be information for classifying the type of the tool. The tool use information is information indicating the necessity of use of the tool in the work process (whether or not) and the work time zone (day / night). For example, regarding the tool B, it is shown that the tool B is used in the daytime in the work process A, the tool B is used in the night in the work process B, and the tool B is not used in the work process C. The daytime here is, for example, a time zone from 6:00 am to 6:00 pm, and the night time is, for example, a time zone from 6:00 pm to 6:00 am.

The entrance / exit image DB11c shown in FIG. 2 stores an entrance / exit image (entrance / exit image) taken by the video recording means 7. The entrance / exit image is preferably one that can identify the entrance / exit person, and may be a whole body image, an upper body image, a face image, or the like of the entrance / exit person.
As shown in FIG. 2, the control unit 12 includes an entrance determination unit 12a, an article removal determination unit 12b, and an abnormality notification unit 12c.
The entry determining means 12a determines whether or not entry into the construction work area 1 is possible. The information of the entrance card P read by the visitor information reading means 3 (for example, a construction-related person ID) is input to the entrance determining means 12a. The entrance determining means 12a refers to the construction-related person DB using the construction-related person ID of the entrance card P as a key, and acquires corresponding entry availability information.

  In addition, information on the head of the visitor (for example, an image near the head and temperature information) acquired by the head information acquiring means 4 is input to the entrance determining means 12a. When the former information (head image) is input, the entrance determination unit 12a determines whether or not the visitor wears a helmet using, for example, an image recognition technique. The image recognition technology may be a conventionally known technology. For example, a feature amount of a head is extracted from image data and compared with data (feature amount) of a prepared helmet for collation prepared in advance. It is determined whether or not the person wearing the helmet is reflected in the image. Further, the entry determining means 12a may determine whether or not a helmet is worn using so-called artificial intelligence. The artificial intelligence is generated by, for example, learning (for example, deep learning) image data of a person wearing a plurality of helmets.

  When the latter information (head temperature information) is input, the entrance determining means 12a compares the temperature information of the helmet prepared in advance with the acquired temperature information of the head of the visitor, for example. Then, it is determined whether or not the visitor wears a helmet. For example, in a room, it is assumed that the surface temperature of the helmet is lower than the temperature of the human body or the temperature of the hair. Also, for example, outdoors, it is assumed that the surface temperature of the helmet is higher than the temperature of the human body or hair. Therefore, a threshold is set based on the surface temperature of the helmet measured in advance, and it is determined whether or not the visitor wears a helmet based on the acquired relationship between the temperature of the head of the visitor and the threshold.

The entrance determination means 12a determines that the entrance is permitted based on the information stored in the entrance card P, and permits the entrance of the visitor when it is determined that the visitor is wearing a helmet. That is, even if it is determined that entry is permitted based on the information stored in the entry card P, entry of the visitor is not permitted if the visitor does not wear a helmet.
The article take-out determining means 12b determines whether or not the tool can be taken out of the construction work area 1. The information (for example, tool ID) of the tool tag Q read by the tool information reading means 5 is input to the article take-out determination means 12b. Further, current time information and schedule information (for example, current work process) are input to the article take-out determination unit 12b from an external server (not shown).

The article take-out determining means 12b refers to the tool DB 11b using, for example, the tool ID of the tool tag Q and the current work process as keys, and acquires corresponding tool use information. If the tool ID of the tool tag Q is information indicating the tool B and the current is the work process A, the article take-out determination unit 12b acquires tool use information indicating that the tool B is used in the daytime. . Thereby, the article take-out determination unit 12b recognizes whether the tool to be taken out is within the use period, and whether the time at which the tool is taken out is within the working time zone.
If the date and time of passing through the entrance / exit gate 2 is within the use period of the tool to be taken out and is outside the working time of the tool to be taken out, the article take-out determination means 12b removes the tool. To give permission. That is, when the date and time of passing through the entrance / exit gate 2 is determined to be out of the use period of the tool to be taken out or within the working time of the tool to be taken out, the article taking out determination means 12b takes out the tool. Do not allow. Assuming that the tool ID of the tool tag Q is information indicating the tool B, for example, if the date and time of passing through the entrance / exit gate 2 is nighttime in the work process A, take-out is permitted. On the other hand, if the date and time of passing through the entrance / exit gate 2 is the daytime in the work process A or the period of the work process C, taking out is not permitted.

  The abnormality notification unit 12c performs control to notify an abnormality when the entrance of the visitor is not permitted or when the removal of the tool is not permitted. The abnormality notification unit 12c uses the alarm unit 6 to generate an alarm, for example, when the entrance of the visitor is not permitted or when the removal of the tool is not permitted. In addition, the abnormality notifying unit 12c notifies the construction manager that a person who does not permit entry has entered, or has taken out a tool that does not permit entry, and transmits an image of the entry / exit person by e-mail.

<Operation of the entrance / exit management system according to the embodiment>
The operation of the entrance / exit management system 100 according to the embodiment will be described with reference to FIGS. 4 and 5 (see FIGS. 1 to 3 as appropriate). Here, the operation of the entrance / exit management system 100 will be described separately for “entrance determination processing” and “exit determination processing”.
Here, the system manager or the construction manager registers the construction-related person DB 11a and the entrance card P, and distributes the registered entrance card P to the construction-related person in advance. In addition, the system manager or the construction manager registers the tool DB 11b and the tool tag Q, and pastes the registered tool tag Q on the tool in advance. Further, the entrance / exit management system 100 has acquired construction work schedule information according to registration by a system manager or a construction manager or notification from an external server (not shown).

(Admission judgment processing)
With reference to FIG. 4, an entry determination process by the entry / exit management system 100 will be described.
When the visitor approaches the entrance / exit gate 2, the entrance / exit management processing by the entrance / exit management system 100 is started. When the visitor enters the photographing range of the image recording means 7, the image recording means 7 starts photographing the visitor (step S11). The video (including the image) captured by the video recording means 7 is stored in the entrance / exit image DB 11c.
When the visitor further approaches the entrance / exit gate 2 and enters a range where the radio wave emitted by the visitor information reading means 3 reaches, the visitor information reading means 3 stores the information stored in the entrance card P carried by the visitor. (For example, construction person ID) is read (step S12). Next, the visitor information reading means 3 determines whether or not the reading of the entrance card P has been correctly performed (step S13).

If the reading is not performed correctly (“No” in step S13), the abnormality notification unit 12c generates an alarm using the alarm unit 6 and sends the image of the visitor to the construction manager or the system administrator by e-mail. It transmits (step S18). On the other hand, when the reading has been performed correctly (“Yes” in step S13), the entrance determination unit 12a refers to the construction-related person DB 11a and determines whether the read person with the construction-related person ID can enter. (Step S14).
If the person is not a construction-related person who can enter ("No" in step S14), the process proceeds to step S18 to issue an alarm or the like (step S18). On the other hand, if the person is a construction-related person who can enter (“Yes” in step S14), the head information acquisition unit 4 acquires an image of the head of the visitor or temperature information (step S15). Next, the entry determining unit 12a determines whether the visitor wears a helmet using the image of the visitor's head or the temperature information (step S16).

  If a helmet is not worn ("No" in step S16), the process proceeds to step S18 to issue an alarm or the like (step S18). On the other hand, when the helmet is worn ("Yes" in step S16), the entry determining means 12a sets the entry / exit category of the construction-related person DB 11a to "entry" and ends the entry determination processing. This allows entry.

(Exit judgment processing)
With reference to FIG. 5, the exit determination processing by the entrance / exit management system 100 will be described.
The exit determination process by the entrance / exit management system 100 is started when the exited person approaches the entrance / exit gate 2. When the visitor enters the shooting range of the video recording unit 7, the video recording unit 7 starts capturing the exiting person (step S21). The video (including the image) captured by the video recording means 7 is stored in the entrance / exit image DB 11c.
When the exiting person further approaches the entrance / exit gate 2 and enters the range where the radio wave radiated by the entrance information reading unit 3 reaches, the entrance information reading unit 3 stores the information stored in the entrance card P carried by the exiting person. (For example, construction person ID) is read (step S22). Next, the visitor information reading means 3 determines whether or not the reading of the entrance card P has been correctly performed (step S23).

When the reading is not performed correctly (“No” in step S23), the abnormality notification unit 12c generates an alarm using the alarm unit 6, and sends the image of the exiting person to the construction manager or the system administrator by e-mail. The data is transmitted (step S28). On the other hand, when the reading is correctly performed (“Yes” in step S23), the tool information reading unit 5 reads information (for example, a tool ID) stored in the tool tag Q attached to the tool (step S24). .
Next, the article take-out determination means 12b refers to the tool DB 11b to determine whether or not the current date and time (date and time when passing through the entrance / exit gate 2) is within the use period of the tool to be taken out (step S25). ). If it is not within the use period of the tool ("No" in step S25), the process proceeds to step S28 to perform an alarm or the like (step S28). On the other hand, if it is within the use period of the tool (“Yes” in step S25), the article take-out determination unit 12b refers to the tool DB 11b and takes out the current time (the time when the vehicle passed the entrance / exit gate 2). It is determined whether or not the time is outside the working hours of the tool (step S26).

If it is not during the working time period of the tool ("No" in step S26), the process proceeds to step S28 to issue an alarm or the like (step S28). On the other hand, when the time is outside the working time zone of the tool (“No” in step S26), the article take-out determination unit 12b sets the entry / exit category of the construction-related person DB 11a to “exit” and ends the exit determination processing. This allows the removal of the tool.
In addition, about the tool which all the work processes were completed or are no longer used in the subsequent work processes, for example, the system manager or the construction manager deletes the information registered in the tool DB 11b and the tool tag Q, It is preferable to take out tools from the entrance / exit gate 2 to the outside of the construction work area 1. Further, the system manager or the construction manager does not delete the information registered in the tool DB 11b and the tool tag Q, and deletes another route in which the entrance / exit gate 2 is not installed (for example, a route that is strictly locked). You may take your tools out of the office.

As described above, the entrance / exit management system 100 according to the present embodiment is designed such that when a malicious third party obtains the entrance card P (first recording medium) of a regular visitor and tries to enter, It is determined whether or not the helmet which is a necessity of the concerned person is worn. Therefore, it is possible to reduce the possibility that a third party enters the construction work area 1 by an unauthorized method.
In addition, the entrance / exit management system 100 according to the present embodiment permits taking out tools (articles) used for construction work for maintenance, but restricts other taking out. Therefore, even if a third party enters the construction work area 1 by an unauthorized method, it is possible to reduce the possibility that a tool is taken out by an unauthorized intruder.

[Modification]
As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the embodiments, and can be implemented within the scope of the claims. Modifications of the embodiment will be exemplified below.
In the embodiment, it is assumed that the visitors and the exiters enter and exit from the same place. However, an entrance to enter the construction work area 1 and an exit to exit from the construction work area 1 are provided separately. You may. In this case, for example, an entrance gate for entering and an exit gate for exiting are separately installed, and each function of the entrance / exit gate 2 described in the embodiment is dispersed and set as an entrance gate or exit gate. I do.
Further, in the embodiment, when it is determined that the date and time of passing through the entrance / exit gate 2 is within the use period of the tool to be taken out and is outside the working time of the tool to be taken out, the taking out of the tool is permitted, Otherwise, he did not allow the removal of tools. However, the condition for restricting the removal of the tool is not limited to this. For example, regardless of the work time zone, if the date and time of passing through the entrance / exit gate 2 is within the use period of the tool to be taken out, the tool may be permitted to be taken out. In this case, a tag may be attached to the construction material to restrict the removal of the construction material as in the case of the tool. The construction material is an example of an article used in the construction work.
In the exit determination process of the embodiment, the exit permission is determined based on the relationship between the exit date and time and the tool use period, and the relationship between the exit time and the tool working time zone. In addition, a construction worker who uses a tool is permitted to take out the tool, and other exiters are determined not to permit taking out the tool even if the above two types of determination conditions are OK. It is good as a method.
