Description

  The present invention relates to a mobility management system, and more particularly to a mobility management system that manages the direction of movement of a management target between two adjacent areas.

2. Description of the Related Art Conventionally, a passing number detection device has been proposed that can detect whether or not a person has passed the position by using a sensor provided at a predetermined passing position and count the number of passing persons. According to this passing number detection device, for example, by installing a sensor at the entrance of a certain venue, the number of people entering the venue can be automatically counted.
In the above-described conventional number-of-passengers detection apparatus, since many expensive sensors such as cameras are used in order to improve the accuracy of detecting humans, the system cost is high.

On the other hand, as shown in Patent Document 1 below, an expensive camera such as a camera is installed by installing a photosensor group composed of a plurality of photosensors arranged in a direction perpendicular to the human movement direction at the passing position. Development of a passing-through number detection device that enables highly accurate detection at low cost without using a simple sensor is in progress. In addition, in the passing person detecting device described in Patent Document 1, the optical sensor group is provided in two rows in the direction in which the person moves, so that the moving direction of the passing person can be grasped.
Japanese Patent Laid-Open No. 10-79012

  However, the passing number detecting device described in the above-mentioned Patent Document 1 merely counts the number of passing persons and specifies the moving direction, and no measures are taken to restrict movement in a specific direction. In addition, when such movement is restricted, no measures are taken as to what kind of target person is restricted. For this reason, when it is desired to restrict movement of a person in a specific direction between areas, these cannot be automatically performed.

  This invention is made | formed in view of the point mentioned above, The subject of this invention is providing the movement management system which can control automatically the movement to the specific direction between areas.

  A mobility management system according to a first aspect of the present invention is a mobility management system for managing a movement direction at a boundary between a first area and a second area to be mobility managed, a transmitter, a first receiver, and a second reception. A machine, passage restriction means, and a control unit. The transmitter is carried by the mobility management target and transmits a specific signal for specifying itself. The first receiver receives a specific signal from a transmitter present in the first area and does not receive a specific signal from a transmitter present in the second area. The second receiver receives a specific signal from a transmitter existing in the second area and does not receive a specific signal from a transmitter present in the first area. The passage restriction means is provided at the boundary between the first area and the second area, and realizes a permission mode that permits passage of the movement management target and a restriction mode that restricts passage. When the first receiver receives the specific signal from the same transmitter after the first receiver receives the specific signal from the transmitter, the control unit sets the passage restriction means in the permission mode. When the second receiver receives the specific signal from the transmitter and does not satisfy the permission condition, the passage restriction unit is controlled to enter the restriction mode. Note that the movement management target here includes not only a person who can move by his / her own intention but also an object that cannot be moved by his / her own intention. This object is an object of the present invention when it is moved together with humans or mechanically moved. The passage restriction means includes not only a physical partition such as a door, but also a warning by displaying a red / blue signal, a warning by an alarm buzzer sound, and the like. Here, the first area and the second area do not necessarily mean only areas that are spatially partitioned. That is, a specific space or the like in which a first receiver or a second receiver can receive a specific signal from a transmitter in a spatially partitioned space is included.

In the conventional movement management system, there is no treatment or configuration for restricting movement in a specific direction between areas, and no treatment for what kind of target movement is restricted.
On the other hand, in the mobility management system of the first invention, for the mobility management object carrying the transmitter that transmits the specific signal, the first receiver grasps the presence / absence of the transmitter in the first area; The receiver can determine whether or not there is a transmitter in the second area. And when the control unit satisfies the permission condition that the second receiver receives the specific signal from the same transmitter for the first time after the first receiver receives the specific signal from the transmitter, the passage restriction means Is controlled to be in permission mode. Thereby, the movement in the forward direction can be automatically permitted for objects that satisfy the permission condition among the movement management objects. In addition, the control unit 70 controls the passage restriction unit to be in the restriction mode when the second receiver receives the specific signal from the transmitter and does not satisfy the permission condition. Thereby, retrogression can be automatically suppressed for a target that does not satisfy the permission condition among the mobility management targets.
Therefore, it becomes possible to automatically regulate movement in a specific direction between areas for each movement management object carrying the transmitter.

A mobility management system according to a second aspect is the mobility management system according to the first aspect, wherein the control unit receives a specific signal from the same transmitter after the first receiver receives the specific signal from the transmitter. When the second receiver receives again a specific signal from the same transmitter after a lapse of a predetermined time from the first reception by the two receivers, control is performed to set the passage restriction means to the restriction mode.
Here, when the second receiver receives a specific signal from the same transmitter for the first time after reception by the first receiver and the movement management target enters the second area, the restriction mode is set after a predetermined time has elapsed. Control is in progress. Thereby, it becomes possible to suppress the movement management object remaining in the second area from returning to the first area again.

A mobility management system according to a third invention is the mobility management system according to the first invention or the second invention, and the control section controls the restriction mode with priority over the permission mode in the control of the passage restriction means.
Here, the restriction mode is preferentially applied to the first receiver and the second receiver even if the timings of receiving specific signals from different transmitters may overlap. As a result, it becomes possible to thoroughly prevent the retrograde and more reliably regulate the retrograde.

  A mobility management system according to a fourth aspect of the present invention is the mobility management system according to any one of the first to third aspects of the present invention, wherein the passage restriction means is a door that is locked so as not to open when the restriction mode is realized, It has at least any one of the automatic door made into the closed state, the alerting | reporting apparatus notified by an audio | voice, and the alerting | reporting lamp alert | reported by a display.

  Here, when the restriction mode is realized, the passage restriction means is any one of a door that is locked so as not to open, an automatic door that is closed, a notification device that informs by voice, and a notification lamp that informs by display. Is done. Here, since the door is locked so as not to be opened in the restriction mode, it is possible to effectively prevent the retrograde operation. Moreover, since the automatic door is also closed in the restriction mode, it is possible to effectively prevent the retrograde operation. Further, since the notification device can notify the movement management object and the like by voice notification in the restriction mode, it can effectively prevent the retrograde. In addition, since the notification lamp can be notified by display in the restriction mode to notify the movement management object or the like, it is possible to effectively prevent retrograde. As described above, even if any of a door, an automatic door, a notification device, and a display lamp is adopted as the passage restriction means, it becomes possible to effectively restrict the retrograde movement between areas subject to movement management.

  A mobility management system according to a fifth aspect of the present invention is the mobility management system according to any one of the first to fourth aspects of the present invention, provided near the first area, and includes temperature management, humidity management, atmospheric pressure management, and sterilization. Hygiene management means for performing at least one of hygiene management of management, dust removal management, and deposit removal management is further provided. In the first area, a higher level of hygiene management is performed by the hygiene management means than in the second area. For example, in hygiene management, when temperature and humidity are targeted, the cleaning means corresponds to an air conditioner or the like.

If an object staying in a place where only a low level of cleanliness is managed moves to a place where cleanliness is managed at a high level, it will be difficult to maintain a high level of cleanliness There is.
On the other hand, here, when managing movement between areas having different cleanliness, it is possible to prevent movement from a contaminated area to an area where the cleaning management is performed by the cleaning means. For this reason, it becomes possible to suppress the invasion of dust, dust, bacteria, etc. into the area where the clean management is performed, and to improve the quality of the hygiene management.
In addition, when performing the cleaning management, it is possible to reduce the load when operating the cleaning means.

  The mobility management system according to a sixth aspect of the present invention is the mobility management system according to any one of the first to fifth aspects, wherein the second receiver receives from the transmitter that is received when the passage restriction means is in the restricted mode. A history memory for recording the specific signal is further provided.

Here, a history is recorded for each movement management object with respect to the movement management object that has created the cause of setting the passage restriction means to the restriction mode. For this reason, it can be used for the later management about the movement management object which went back and forth between areas.
For example, it becomes possible to call attention as a violator for a movement management object that frequently goes back, based on the history memory, and can be used as one means for raising hygiene management awareness.

In the mobility management system according to the first invention, it is possible to automatically regulate movement in a specific direction between areas for each mobility management object carrying a transmitter.
In the mobility management system according to the second aspect of the present invention, it is possible to prevent the mobility management object that remains in the second area from returning to the first area again.
In the mobility management system according to the third aspect of the present invention, it is possible to thoroughly prevent the retrograde and more reliably regulate the retrograde.

In the mobility management system according to the fourth aspect of the present invention, even if any of a door, an automatic door, a notification device, and a display lamp is adopted as the passage restriction means, the backward movement between the areas subject to mobility management is effectively restricted. It becomes possible.
In the movement management system according to the fifth aspect of the present invention, therefore, it is possible to suppress the invasion of dust, dust, bacteria, etc. into the area where the clean management is performed, and to improve the quality of the hygiene management.

  In the mobility management system according to the sixth aspect of the present invention, it can be used for later management of a mobility management object that has gone back and forth between areas.

<Outline of the Invention>
The present invention provides an entrance hygiene management system and the like for managing the moving direction at the boundary between the first area and the second area to be moved. In the admission sanitation management system of the present invention, an RFID transmitter is carried as a movement management object. The first receiver receives a specific signal from the RFID transmitter existing in the first area, and the second receiver receives a specific signal from the RFID transmitter present in the second area. For this reason, the presence or absence of the movement management object in the first and second areas can be determined based on whether or not the specific signal is received by the first and second receivers. In addition, it is possible to specify which mobility management target exists by a specific signal from the RFID transmitter received by the first and second receivers. Thereby, the control of permitting movement in a predetermined direction and restricting movement in the reverse direction can be automated to suppress the backward movement of the movement management target.

Hereinafter, the entrance hygiene management system 100 of the present invention will be specifically described.

As shown in FIG. 1, the operator 20 moves from the external area A5 to the air shower room A1, the clean area A2, the semi-clean area A3, and the contaminated area A4 in order from the outside area A5, while performing a predetermined cleaning process. Then, work related to food will be performed, and it will be in the external area A5. In this food factory, from the viewpoint of hygiene management, movement that goes backward in the above-described movement direction (forward direction) is regulated. For example, the worker 20 staying in the semi-clean area A3 is prohibited from going back to the clean area A2 in the same state, and only after having left the external area A5 and re-executed the cleaning process. Cannot enter clean area A2.

  Here, as the cleaning process imposed on the worker 20 to which the RFID tag 30 is attached, as shown in FIG. Work to remove dust and dust using a roller 91 is imposed. And the operator 20 who finished the removal operation | work by the roller 91 performs the operation | work which wash | cleans a hand sufficiently using a detergent and disinfects. Next, the body temperature of the operator 20 who is going to enter is measured without contact. The worker 20 whose body temperature has been measured further enters the air shower room A1, receives the air shower, and removes dust, bacteria, and the like attached thereto. Only the worker 20 who is recognized to have properly performed both of these can enter the clean area A2.

Here, it is judged by the admission management device 1 of the admission hygiene management system 100 using the RFID tag 30 whether or not the entire cleaning process has been sufficiently performed for each worker 20, and admission permission is not permitted. Is managed.

The roller 91 uses the operation portion for the hand, and a fingerprint authentication sensor 80 is provided on the surface of the operation portion, and an acceleration sensor 81 is provided inside the operation portion. When the dust removal by the roller 91 is performed, the fingerprint authentication acquisition data D8 is acquired from the fingerprint authentication sensor 80 and compared with the data in the fingerprint authentication management data D1 stored in the database 60. Further, as shown in FIG. 2, the entrance management apparatus 1 is attached to the operator 20 who is operating the roller 91 by the authentication receiver 46 at the same time that the fingerprint authentication acquisition data D8 is acquired. The specific signal of the RFID tag 30 is received. Thereby, the entrance management apparatus 1 associates the fingerprint authentication acquisition data D8 with the received specific signal of the RFID tag 30, and stores it in the database 60 as RFID association data D2. As a result, the admission management device 1 determines whether or not to perform each process based on the specific signal of the RFID tag 30 of the worker 20 without performing biometric authentication work every time for each process of subsequent cleaning. can do.

  As shown in FIG. 2, the water washing device 92 is used in a hand washing corner, and has an infrared sensor (not shown), a portion from which a cleaning liquid is discharged, and a portion from which water is discharged. The water washing device 92 can discharge the cleaning liquid and water for a predetermined time or a predetermined amount only by the operator 20 holding his hand toward the infrared sensor. Thereby, since the operator 20 can perform sterilization cleaning of a hand, without performing operation | movement, such as touching a faucet and twisting, it is hygienic. Also in this case, the admission management device 1 causes the hand-washing receiver 47 to determine whether or not a specific signal is received for each RFID tag 30 and performs each process for each worker 20 (for each specific signal for the RFID tag 30). The data of the presence or absence of is stored.

  As shown in FIG. 2, the non-contact body temperature measuring device 93 is used at a body temperature measurement corner, and includes a non-contact temperature sensor 83 for measuring the body temperature of the operator 20 in a non-contact manner, and a measurement point adjusting function (not shown).

The non-contact body temperature measurement device 93 controls the measurement position of data corresponding to the specific signal of the RFID tag 30 received by the body temperature measurement receiver 48 based on the individual body temperature measurement point management data D3 of the database 60, Sensing is performed by specifying the position of the face for each worker 20, and body temperature data for each worker 20 is measured in a non-contact and reliable manner. The measured body temperature is compared with the corresponding data of the individual normal heat data D4 stored in the database 60, and admission permission / non-permission is controlled.

  As shown in FIG. 2, the air shower 94 is used in the air shower room A1, and operates from various directions with an infrared sensor (not shown) that detects that the operator 20 has entered the air shower room A1. And an air blowing portion (not shown) for applying air pressure to the person 20. Also in this case, the entrance management device 1 causes the air shower receiver 51 to determine whether a specific signal is received for each RFID tag 30.

  The air conditioner 16 adjusts temperature, humidity, atmospheric pressure, sterilization, and the like for the clean area A2. In the sterilization function, sterilization of fungi and the like present in the air is performed. The air conditioner 16 is connected to the admission management device 1 as shown in FIG. 3, and is controlled to increase the cleanliness level of the clean area A2. Further, the air flow is formed in the quasi-direction by controlling the atmospheric pressure. This prevents bacteria from moving on the air flow.

  The exit-side receiver 40 is a receiver that receives a specific signal within a predetermined range from the RFID tag 30 attached to the hat of the worker 20, and includes an external area exit-side receiver 41 and an air shower exit-side receiver. 42, a clean area exit side receiver 43, a semi-clean area exit side receiver 44, and a contaminated area exit side receiver 45. As shown in FIG. 1, the external area exit-side receiver 41 is installed near the exit of the external area A5 in the forward direction, and is attached to the worker 20 present in the exit vicinity area A51 of the external area A5. The specific signal from the RFID tag 30 is received. In addition, the air shower exit side receiver 42, the clean area exit side receiver 43, the semi-clean area exit side receiver 44, and the contaminated area exit side receiver 45 are the same as the external area exit side receiver 41, It is installed on the exit side in the forward direction of each area, and receives a specific signal from the RFID tag 30 attached to the worker 20 existing in each exit vicinity area A41, A42, A43, A44, A45. To do. Also in this case, the entrance management device 1 causes the outlet-side receiver 40 to determine whether or not a specific signal for each RFID tag 30 has been received.

  The entrance-side receiver 50 is a receiver that receives a specific signal within a predetermined range from the RFID tag 30 attached to the hat of the operator 20, and includes an air shower entrance-side receiver 51 and a clean area entrance-side receiver. 52, a semi-clean area entrance-side receiver 53, a contaminated area entrance-side receiver 54, and an external area entrance-side receiver 55. As shown in FIG. 1, the air shower entrance-side receiver 51 is installed in the vicinity of the entrance of the air shower room A1 in the forward direction, and is attached to the worker 20 existing in the entrance vicinity area A51 of the air shower room A1. A specific signal is received from the RFID tag 30 that has been set. Further, the clean area entrance side receiver 52, the semi-clean area entrance side receiver 53, the contaminated area entrance side receiver 54 and the external area entrance side receiver 55 are the same as the air shower entrance side receiver 51, It is installed on the entrance side in the forward direction of each area, and receives a specific signal from the RFID tag 30 attached to the worker 20 existing in each of the entrance vicinity areas A52, A53, A54, A55. Also in this case, the entrance management device 1 causes the entrance-side receiver 50 to determine whether a specific signal is received for each RFID tag 30.

As shown in FIG. 3 and FIG. 2 showing the system block diagrams, the entrance management device 1 is mainly composed of a database 60, a CPU 70, a ROM 71, and a RAM 72.
As shown in FIG. 3, the database 60 stores fingerprint authentication management data D1, RFID association data D2, individual body temperature measurement point management data D3, individual normal heat management data D4, and violator history data D5. Among these, the fingerprint authentication management data D1 is data obtained by acquiring a fingerprint for each worker 20 in advance and storing the fingerprint in association with each worker 20. The RFID association data D2 is data in which the fingerprint authentication acquisition data D8 and the specific signal from the RFID tag 30 are associated as described above. The individual body temperature measurement point management data D3 is data of the height position of each individual face acquired in advance in order to accurately measure the body temperature of each individual by the non-contact temperature sensor 83. The individual heat management data D4 is heat data acquired in advance for each individual. The violator history data D5 is stored in association with a specific signal of the corresponding RFID tag 30 in order to identify the worker 20 when the worker 20 does not move in the forward direction but moves in the reverse direction. It is data. In addition to this, data about the worker 20 who does not perform the cleaning process is also stored.

<Specific example of admission management of admission hygiene management system 100>
In this entrance hygiene management system 100, as described above, only the worker 20 who has performed a plurality of processes such as rollers, hand washing, body temperature measurement, and air shower can enter the clean area A2. Here, a specific determination example for each process will be described with reference to FIG. 4 from above.

First, fingerprint authentication by the fingerprint authentication sensor 80 using the roller 91, registration by a specific signal from the RFID tag 30, detection by the acceleration sensor 81 indicating that the roller has been fully used, and the authenticated worker 20 is in a normal temperature. There are certain processes of performing an air shower and entering, and this worker 20 is allowed to enter the clean area A2.
Next, in fingerprint authentication, if there is no data corresponding to the fingerprint authentication management data D1 in the database 60, the admission management device 1 “spoofs” that the person is an outsider who is illegally entering. It is determined that the worker 20 and cannot enter.

  If the operator 20 does not perform fingerprint authentication without touching the roller 91 and enters the air shower room, there is no authentication data associated with the RFID association data D2 of the database 60. The entry management device 1 determines that the worker 20 is “spoofing” and is unable to enter because it is an outsider who tries to infiltrate the execution of the process.

On the other hand, the fingerprint authentication is performed by the operator 20 touching the roller 91, but if the acceleration sensor 81 does not detect the dust removal by the roller 91 sufficiently, the worker 20 is sufficiently cleaned. It is determined that the worker 20 is “unsanitary” by the entrance management device 1 and cannot enter.
In addition, even if the worker 20 has cleared the work such as the operation by the roller 91 or the normal heat, when the user is about to enter the clean area A2 without performing the air shower, the entrance management device 1 " It is determined that the worker 20 is entering from an “illegal place” and cannot enter.

Next, when the body temperature of the worker 20 measured by the non-contact temperature sensor 83 does not match the individual normal heat data D4 in the database 60 or is not within a predetermined error range, the admission management device 1 causes “bad physical condition”. It is determined that the worker 20 is "20" and cannot enter.
Finally, in the case of entering without being subjected to fingerprint authentication or the like, it is assumed that the person is an outsider trying to intrude illegally, and the entrance management apparatus 1 performs an “intruder” worker 20. I can't enter.
Thereby, the worker 20 who can enter the clean area A2 or the like can be limited to a specific sanitary person, and hygiene management can be performed thoroughly.

<Anti-reverse management of admission sanitation management system 100>
The retrograde prevention management of the admission sanitation management system 100 will be described with reference to FIG. In addition, although the opening / closing control of the contaminated area automatic door 14 in the case of preventing the retrograde from the contaminated area A4 to the semi-clean area A3 will be described here, the same applies to the other automatic doors 10.

  First, when the operator 20 enters the semi-clean area exit vicinity area A44, the semi-clean area exit side receiver 44 receives the specific signal of the RFID tag 30 attached to the operator 20. Then, the admission management device 1 that has grasped the reception of the semi-clean area exit side receiver 44 has received the specific signal from the RFID tag 30 in the contaminated area entrance vicinity area A54 at the contaminated area entrance side receiver 54. To check. Here, in the admission management device 1, when it is determined that there is no reception of the contaminated area entrance-side receiver 54, control is performed to open the contaminated area automatic door 14 (permission mode). As a result, the contaminated area automatic door 14 is opened when the worker 20 moves in the forward direction, and is prevented from going backward.

  When the operator 20 is present in the contaminated area entrance vicinity area A54, as described above, the contaminated area automatic door 14 is controlled to be closed (restricted mode) in preference to the permission mode. . However, in this case, the worker 20 who is going to move in the forward direction cannot pass. For this reason, by sounding a buzzer device (not shown) attached to the contaminated area automatic door 14, the worker 20 existing in the contaminated area entrance near area A54 is in the vicinity of the contaminated area entrance. A warning sound is issued to call attention to leave the area A54. Thereby, the movement of the worker 20 who is going to move in the forward direction can be realized while preventing the backward movement.

  Furthermore, the admission management device 1 automatically opens the automatic door when the contaminated area entrance-side receiver 54 receives a specific signal from the same RFID tag 30 again after a predetermined time or more has passed since entering the contaminated area entrance vicinity area A54. Control is performed so that 10 is the limit mode. For this reason, it is possible to suppress the worker 20 staying in the contaminated area entrance vicinity area A54 from going back to the semi-clean area A3 again.

<Characteristics of the entrance hygiene management system 100 of this embodiment>
(1)
In the conventional entrance hygiene management system, there are no measures or configurations for restricting movement in a specific direction between areas, and no measures are taken regarding what kind of target movement is restricted. Absent.

  On the other hand, in the entrance hygiene management system 100 according to the present embodiment, the RFID tag 30 in the air shower outlet vicinity area A42 by the air shower outlet side receiver 42 for the worker 20 to which the RFID tag 30 is attached, for example. And the presence / absence of the RFID tag 30 in the clean entrance vicinity area A52 by the clean area entrance-side receiver 52 can be grasped. Then, the admission management device 1 permits the clean area entrance-side receiver 52 to receive the specific signal from the same RFID tag 30 for the first time after the air shower outlet-side receiver 42 receives the specific signal from the RFID tag 30. When the condition is satisfied, the clean area automatic door 12 is controlled to automatically open. Thereby, the movement in the forward direction can be automatically permitted for the worker 20 who satisfies the permission condition. In addition, the entrance management device 1 receives the specific signal from the RFID tag 30 by the clean area entrance receiver 52 and does not satisfy the permission condition (for example, when a predetermined time or more elapses), the clean area automatic door 12. Is controlled to be closed. Thereby, it is possible to automatically prevent the retrograde of the subject that does not satisfy the permission condition among the workers 20.

Therefore, for each worker 20 to which the RFID tag 30 is attached, the movement in a specific direction between the areas can be automatically controlled, and the area that is relatively contaminated without undergoing any cleaning process. Can be prevented from going back to a clean area, and hygiene management of the clean area can be improved.
(2)
In the entrance hygiene management system 100 according to the present embodiment, the entrance management apparatus 1 uses the same RFID tag after a predetermined time has elapsed since the operator 20 entered the entrance vicinity area A50 (A51, A52, A53, A54, A55). When the entrance side receiver 50 (51, 52, 53, 54, 55) receives the specific signal from 30 again, the automatic door 10 is controlled to be in the restriction mode. For this reason, it becomes possible to suppress the worker 20 staying in the entrance vicinity area A50 (A51, A52, A53, A54, A55) from going back to the original area again. Further, even if the operator 20 is one end away from the entrance vicinity area A50 (A51, A52, A53, A54, A55), the entrance vicinity area A50 (A51, A52, A53, A54, A55) is again entered after a predetermined time has elapsed. When entering, the entrance-side receiver 50 receives the specific signal from the RFID tag 30, so that the entrance management apparatus 1 performs control to set the automatic door 10 to the restricted mode. Thereby, the retrograde between the areas of the operator 20 can be reliably prevented.

(3)
In the entrance hygiene management system 100 according to the present embodiment, the restriction mode is given priority even if the timing of receiving specific signals from different transmitters at the exit-side receiver 40 and the entrance-side receiver 50 may overlap. Is applied to. As a result, it is possible to thoroughly prevent the retrograde and control the retrograde more reliably.

(4)
In the entrance hygiene management system, when an object staying in a place where only low-level clean management is performed moves to a place where high-level clean management is performed, high-level cleanliness is maintained. May be difficult to do.
On the other hand, in the entrance hygiene management system 100 according to the present embodiment, the air conditioner 16 for managing each of temperature, humidity, atmospheric pressure, and sterilization is installed in the clean area A2. Thereby, hygiene management of a higher level is performed in the clean area A2 by the air conditioner 16 than in the semi-clean area A3.

For example, when food is heat sterilized at a food factory or the like, special hygiene management is not required at the time before the heat sterilization is performed. The admission sanitation management system 100 may be introduced when it is necessary to protect from bacteria and dust until it is packaged and commercialized. That is, in such a factory, the entrance hygiene management system 100 can be applied so as to regulate the movement from the area that handles the food before the heat sterilization treatment to the area that handles the food after the heat sterilization treatment. it can. Thereby, it becomes possible to reduce that bacteria and dust adhere to the foodstuff after heat-sterilization treatment.

(E)
In the admission hygiene management system 100 in the above embodiment, human fingerprint authentication management data D1 that is highly likely to be entered as the operator 20 is stored in the database 60 in advance, and illegal entry by outsiders is prevented during admission management. The case of doing was explained with an example.

  However, the present invention is not limited to this, and the database 60 may not have the fingerprint authentication management data D1. In this case, for example, when receiving a specific signal from the RFID tag 30 at the time of entry, the biometric authentication data of the person may be acquired and stored in association therewith. In this case, management of illegal intrusion or the like cannot be performed, but the effects of preventing complication of authentication of the worker 20 and preventing retrograde in the above embodiment can be sufficiently obtained.

(F)
In the admission hygiene management system 100 in the above-described embodiment, the case where the automatic door 10 is employed as a means for restricting the retrograde of the worker 20 has been described as an example.
However, the present invention is not limited to this, and when the restricted mode is realized, an entrance that employs a door that is locked so as not to open, a notification device that notifies by voice, a notification lamp that notifies by display, and the like is adopted. The hygiene management system 100 may be used.

  Here, since the door is locked so as not to be opened in the restriction mode, it is possible to effectively prevent the retrograde operation. Moreover, since the notification device can also notify the operator 20 and the like by voice in the restriction mode, it is possible to effectively prevent retrograde. In addition, since the notification lamp can also notify the operator 20 and the like by displaying in the restriction mode, it is possible to effectively prevent the retrograde.

Thus, even if any of a door, a notification device, and a display lamp is adopted as a means for regulating the retrograde, the retrograde between areas by the operator 20 can be effectively regulated.
(G)
In the admission sanitation management system 100 in the above embodiment, the admission sanitation management system 100 in which the air conditioner 16 that manages temperature, humidity, atmospheric pressure, and sterilization is installed in the clean area A2 has been described as an example.

However, the present invention is not limited to this, and as a hygiene management measure installed in the clean area A2, for example, hygiene management such as a device that performs dust removal management or a device that manages the removal of deposits is performed. It may be a device.
(H)
In the admission hygiene management system 100 in the above-described embodiment, the admission hygiene management system 100 that measures body temperature in a non-contact manner for the worker 20 who has finished removing dust and washing hands with the roller 91 has been described as an example.
