Description

  The present invention relates to an entrance / exit management system for performing entrance / exit management for a room occupant.

  A laboratory equipped with an inspection device (for example, MRI, CT, or PET) in a medical facility prevents accidents involving magnetic substances and radiation exposure that may occur if a person enters the laboratory without permission. In order to do so, an entry / exit management system may be used. Such an entrance / exit management system performs authentication of a resident so that only authorized medical personnel (such as doctors, nurses, or engineers) can enter the examination room.

  In such a conventional entrance / exit management system, for example, a room-entrant permitted to enter the room has an authentication device such as an ID card storing an ID for uniquely identifying the room-entrant, When entering the examination room, an ID card is inserted into the card information reader provided near the entrance door of the examination room to read the ID, and the read ID is registered in advance on the entrance / exit management system side. By checking with the ID, it has been determined whether to enter the room. For example, Patent Document 1 discloses a system that performs entry / exit management using an ID card that magnetically records identification information, although it is not related to an examination room.

The control unit 63 is a control unit that controls each unit of the alarm device 60.

(Configuration-optical transmission equipment)
The optical transmission device 70 in FIG. 2 is an optical transmission unit and a wall information transmission unit for transmitting information between the anterior chamber 12 and the examination chamber 13 via the shield wall 17. Here, since the inside of the examination room 13 is a special strong magnetic field environment (a radiation environment in the case of a PET room), there is a possibility that deterioration or malfunction may occur in a general electronic device. Cannot be installed. The inspection room 13 is surrounded by a shield wall 17 and the like, and if a communication line passing through the shield wall 17 is laid, the shielding performance of the shield wall 17 deteriorates. Cannot be connected to each other. Furthermore, since the front chamber 12 and the examination room 13 are electromagnetically shielded from each other, the IC tag 20 in the examination room 13 cannot be read from the front room 12. However, when an abnormality occurs inside the examination room 13, the second door 18 may be unlocked by an operation from the inside of the examination room 13.

  Therefore, in the present embodiment, in order to unlock the second door 18 by an operation from the inside of the examination room 13 without performing electrical communication, optical communication through the shield glass 19 of the shield wall 17 is performed. Furthermore, the electronic device is arranged only in the front chamber 12 and the non-electronic device is arranged in the examination room 13 so that information can be transmitted in a special environment. Specifically, as shown in the block diagram of FIG. 8, the optical transmission device 70 includes a light projecting unit 71 and a light receiving unit 72 arranged in the front chamber 12 and a non-electronic emergency unit arranged in the examination room 13.

It is in an arranged state. That is, a person entering the examination room 13 can change the incident state of the light with respect to the light receiving unit 72 by manually changing the direction of the reflecting plate 73, and the incident light quantity from the light receiving unit 72 is changed. Based on the output, the control unit 74 determines the ON / OFF state of emergency unlocking. As described above, by using the optical transmission device 70, information can be transmitted between the anterior chamber 12 and the examination room 13 without providing a communication device in the examination room 13 under a strong magnetic field. Further, since only the reflector 73 which is a non-electronic means is arranged inside the examination room 13, it is possible to prevent the functional performance from being deteriorated even under a special environment such as a strong magnetic field. The specific configuration for changing the direction of the reflecting plate 73 is arbitrary. For example, by fixing the reflecting plate 73 to the upper end of a vertical rotating shaft (not shown), the reflecting plate 73 can be rotated around the vertical rotating shaft. It is good. Alternatively, since it is only necessary to switch the incident state of the light with respect to the light receiving unit 72, it is not always necessary to change the direction of the reflecting plate 73. For example, a light shielding plate or the like can be put in and out between the reflecting plate 73 and the shield glass 19. It is good.

The information corresponding to the item “tag ID” is the same as the tag ID 23 a stored in the storage unit 85 of the IC tag 20. Further, the information corresponding to the item “entrance authority information” is information for determining whether or not a medical person who is going to enter the examination room 13 has the authority to enter the room, for example, a flag indicating the presence or absence of the entry authority. To do. In the example of FIG. 11, flag = “0” indicates no entry authority, and flag = “1” indicates entry authority. The specific configuration of the storage unit 85 is arbitrary, and can be configured using a rewritable storage unit such as HD (Hard Disk).

(processing)
Next, various processes performed in the control unit 84 of the entrance / exit management system 1 will be described. This process includes an entrance / exit management process for performing entrance / exit management for the examination room 13, an interlock process for performing opening / closing control of the first door 15 and the second door 18, and a solution of the second door 18 from the inside of the examination room 13. It is roughly divided into emergency unlocking process for locking. In the following description, each process is performed at an arbitrary timing except for a specially described timing, and a process is performed by the control unit 84 of the system management apparatus 80 except for a subject to be specifically described. In the case where the route is not specified, it is assumed that the route is input via the input unit 82 of the system management apparatus 80 or any other means at a known timing and a known method. “Step” is abbreviated as “S”.

(Processing-entry / exit management processing)
First, the entrance / exit management process will be described. FIG. 12 is a flowchart of the entry / exit management process. First, the control unit 84 monitors whether or not the tag ID 23a stored in the IC tag 20 has been read by the IC tag reading device 30 (SA1). For example, when a medical person who entered the anterior chamber 12 from the corridor 11 through the first door 15 touches the door knob of the second door 18 to enter the examination room 13, the medical person wears it. The tag ID 23a is transmitted from the human body communication unit 21 of the IC tag 20 to the human body communication unit 31 of the IC tag reader 30 by human body communication, and this tag ID 23a is transmitted to the communication unit 81 of the system management device 80. Accordingly, the control unit 84 determines that the tag ID 23a has been acquired, and proceeds to SA2 (SA1, Yes). On the other hand, when the medical staff is not touching the door knob of the second door 18 or when the medical staff is not wearing the IC tag 20, the tag ID 23 a is received from the IC tag 20. Since it is not read, the control unit 84 determines that the tag ID 23a has not been acquired, and continues monitoring SA1 (SA1, No).

  When the process proceeds to SA2, the room entry authority control unit 84a determines whether there is room entry authority information stored in the room entry authority information table 85a in association with the same tag ID 23a acquired in SA1. If there is authority information, it is determined whether or not the room entry authority information is information indicating “with room entry authority”. When it is not “with room entry authority” (SA2, No), the control unit 84 causes the alarm device 60 to display the determination result (SA3) and ends the entrance / exit management process. Although this display method is arbitrary, for example, the alarm device 60 performs display output such as “tag IDs do not match” or audio output.

  On the other hand, when it is “with room entry authority” (SA2, Yes), the control unit 84 causes the alarm device 60 to display the determination result (SA4). Although this display method is arbitrary, for example, the alarm device 60 performs display output such as “tag ID matched” or audio output. Next, the control unit 84 outputs a control signal to the electric lock device 50 to unlock the second door 18 (SA5). Thereby, even when the medical staff enters the examination room 13 from the front room 12 while holding the patient, the medical staff does not need time and effort such as touching the IC tag reading device 30 with the IC tag 20. , Can enter the examination room 13.

  Next, the control part 84 determines whether the 2nd door 18 was opened based on the output from the intrusion detection apparatus 40b (SA6). For example, when the second door 18 is opened by a medical person, the detection unit 41 of the intrusion detection device 40b detects the opening of the second door 18, and the information is transmitted to the communication unit 81 of the system management device 80. The control unit 84 determines that the second door 18 has been opened based on this information.

  When it is determined that the second door 18 has been opened (SA6, Yes), after a predetermined time has elapsed, the control unit 84 determines whether the second door 18 has been closed based on the output from the intrusion detection device 40b. (SA7). For example, while the medical staff transports the patient from the front chamber 12 to the examination room 13 or prepares for the examination while going back and forth between the front room 12 and the examination room 13, the second door 18 is opened. After the completion of these operations, when the second door 18 is closed by a medical person, the detection unit 41 of the intrusion detection device 40b detects the closing of the second door 18, Since the information is transmitted to the communication unit 81 of the system management device 80, the control unit 84 determines that the second door 18 is closed based on this information.

  When the closing of the second door 18 is not detected within a predetermined time after the second door 18 is opened (SA7, No), the control unit 84 causes the alarm device 60 to output an alarm (SA8). The alarm method of the alarm device 60 is arbitrary. For example, the alarm device 60 outputs a sound such as “Please close the second door” to the sound output unit 61 or a buzzer sound.

  When it is determined that the second door 18 is closed (SA7, Yes), the control unit 84 outputs a control signal to the electric lock device 50 to lock the second door 18 (SA9), and the entrance / exit management process Exit. Note that the activation of the MRI 16 may be permitted on the condition that the second door 18 is locked as described above. For example, when the second door 18 is locked, the control unit 84 outputs a lock completion signal to an MRI operation panel (not shown) of the examination room 13, and the MRI operation panel (not shown) uses the lock completion signal as one of the conditions. Activation may be possible.

(Interlock processing)
Next, the interlock process will be described. FIG. 13 is a flowchart of the interlock process. This interlock process is automatically started after a medical person enters the front room 12 from the corridor 11 as in the entrance / exit management process. The door interlock control unit 84b monitors whether or not the first door 15 is opened based on the output from the intrusion detection device 40a (SB1). For example, when the first door 15 is opened by a medical staff, the detection unit 41 of the intrusion detection device 40a detects the opening of the first door 15 and transmits the information to the communication unit 81 of the system management device 80. Thereby, the door interlock control unit 84b determines that the first door 15 is opened.

  When it is determined that the first door 15 is opened (SB1, Yes), the door interlock control unit 84b determines whether the second door 18 is opened by the intrusion detection device 40b (SA2). For example, when a medical staff opens the second door 18, the detection unit 41 of the intrusion detection device 40 b detects the opening of the second door 18, and the information is transmitted to the communication unit 81 of the system management device 80. Thereby, the door interlock control unit 84b determines that the second door 18 is opened.

  When it is determined that the second door 18 is opened (SB2, Yes), the door interlock control unit 84b causes the alarm device 60 to output an alarm (SB3). The alarm method of the alarm device 60 is arbitrary. For example, the alarm device 60 outputs a sound such as “the first door and the second door are open” to the audio output unit 61 or continuously. A buzzer sound is output.

  However, when it is determined that the first door 15 is not opened by the medical staff closing the first door 15 or the second door 18 after entering the front room 12 or the examination room 13 (SB1, No ) Or the second door 18 is determined not to be opened (SB2, No), the door interlocking control unit 84b ends the interlock process without outputting an alarm.

(Intruder detection processing)
Next, intruder detection processing will be described. FIG. 14 is a flowchart of intruder detection processing. The occupant interlocking control unit 84c monitors whether or not the occupant has passed through the first door 15 based on the output from the intrusion detection device 40a (SC1). For example, when a room occupant passes the first door 15, it is detected by the detection unit 41 of the intrusion detection device 40 a that the first door 15 has been passed, and the information is transmitted to the communication unit 81 of the system management device 80. As a result, the occupant interlocking control unit 84c determines that the first door 15 has passed.

  When it is determined that the occupant has passed the first door 15 (SC1, Yes), the occupant interlocking control unit 84c determines whether the occupant has passed the second door 18 by the intrusion detection device 40a. (SC2). If it is determined that the occupant has passed through the second door 18 (SC2, Yes), the occupant has the authority to enter the room when passing through the second door 18 in SA2 of the entrance / exit management process of FIG. It is determined whether or not it has been confirmed (SC3). When it is determined that the confirmation has been made (SC3, Yes), the occupant interlocking control unit 84c terminates the intruder detection process without outputting an alarm.

  On the other hand, when it is determined that it has not been confirmed (SC3, No), the occupant interlocking control unit 84c causes the alarm device 60 to output an alarm for a predetermined time (SC4). Although the alarm method of the alarm device 60 is arbitrary, for example, the alarm device 60 outputs a sound such as “an intruder has entered” to the sound output unit 61 or outputs a continuous buzzer sound or the like. To do. For example, a medical person having authority to enter the room passes through the first door 15 and the second door 18 while a person who does not have authority to enter the room passes through the first door 15 and the second door 18 while leaving the first door 15 and the second door 18 open. In such a case, such alarm output is performed. This completes the intruder detection process.

(Emergency unlocking process)
Next, the emergency unlocking process will be described. FIG. 15 is a flowchart of the emergency unlocking process. The wall information control unit 84d monitors whether or not the emergency unlocking is ON based on the output from the optical transmission device 70 (SD1). For example, when the physical condition of the patient in the examination room 13 is not excellent, the patient touches the reflection plate 73 as an emergency unlocking switch and changes the direction of the reflection plate 73. When the light receiving unit 72 cannot receive the light projected from the unit 71, the light receiving state of the light receiving unit 72 is output from the optical transmission device 70 to the system control device 80.

  If it is determined that the emergency unlocking is ON (SD1, Yes), the wall information control unit 84d outputs a control signal to the electric lock device 50 to urgently unlock the second door 18. (SD2). Note that when the emergency unlocking is turned on as described above, the operation of the MRI 16 may be automatically stopped. For example, when emergency unlocking is turned ON, the control unit 84 outputs an emergency stop signal to an MRI operation panel (not shown) of the examination room 13, and the MRI operation panel (not shown) stops the operation of the MRI 16 or an alarm device. An alarm may be output at 60 to notify the medical personnel in the front room 12 of the abnormality. This completes the emergency unlocking process.

(effect)
Thus, according to the first embodiment, the first door 15 and the second door based on the entrance control based on the occupant information and the entrance authority information, the detection result of the intrusion detection device 40a, and the detection result of the intrusion detection device 40b. By performing both of the two types of entrance / exit management with the 18 interlocking controls, entrance / exit management with respect to the examination room 13 can be performed more reliably than in the past.

  Further, by reading the occupant information stored in the IC tag 20 by human body communication, it is possible to save the labor of authenticating the occupant, so even if the front room 12 and the examination room 13 have a double door structure, The entrance / exit management for the examination room 13 can be performed easily and smoothly.

  Moreover, even if it is a case where the front room 12 and the inspection room 13 have a double door structure by the room attendant interlocking control based on the detection result of the person entering the inspection room 13 from the front room 12, the room passing through each door. Therefore, the entrance / exit management with respect to the examination room 13 can be more reliably performed.

  Further, since the examination room 13 is configured as a shield room, even if information cannot be transmitted between the examination room 13 and the front room 12 via an electric signal or radio wave, the shield wall Since information transmission via the optical transmission device 70 can be performed by the optical transmission device 70, it is possible to transmit information between the examination room 13 and the front room 12. For example, when an abnormality occurs in the examination room 13, the examination room 13 side The safety and convenience can be improved, for example, the second door 18 can be emergency unlocked by an operation from.

  In addition, since information transmission through the shield glass 19 of the shield wall 17 can be performed by the optical transmission device 70, information transmission between the examination room 13 and the front chamber 12 can be performed easily and reliably.

[Embodiment 2]
Next, a second embodiment will be described. In the second embodiment, in the case where the examination room 13 is an MRI room, in order to prevent a magnetic material carry-in accident that may occur when a metal is inadvertently brought into the examination room 13, This is a form in which entrance / exit management is performed using the detection result of the metal detection performed. However, unless otherwise specified, the configuration and processing shown in the second embodiment are the same as the configuration and processing shown in the first embodiment, and the same contents as the configuration and processing shown in the first embodiment are necessary. Accordingly, the same reference numerals as those used in the description of the first embodiment are used, and the description thereof is omitted.

(Configuration-metal detector)
The entrance / exit management system 1 according to the second embodiment is configured to further include a metal detector 90 with respect to the entrance / exit management system 1 according to the first embodiment. The metal detector 90 is a metal detection means for detecting a metal for a person who enters the examination room 13, and is configured in a gate type having a size and shape that allows a person to pass, for example, like an airport security gate. In order to pass through the metal detector 90 when entering the examination room 13, the inside of the front chamber 12 is disposed at a position closest to the second door 18.

  As shown in the block diagram of FIG. 16, the metal detector 90 includes a metal detector 91 and a controller 92. The metal detection unit 91 uses, for example, electromagnetic induction, and detects the metal by detecting a magnetic field associated with eddy current generated when the metal passes through the detection coil. The control unit 92 is a control unit that controls each unit of the metal detector 90, and outputs a detection signal to the system control device 80 when metal is detected by the metal detection unit 91.

(processing)
Next, the entrance / exit management process performed in the control part 84 of this entrance / exit management system 1 is demonstrated. FIG. 17 is a flowchart of the entrance / exit management process. However, SE1 and SE5 to SE10 in FIG. 17 are the same as SA1 and SA4 to SA9 in FIG. First, when it is determined that the tag ID 23a is acquired in SE1 (SE1, Yes), the control unit 84 determines whether or not there is a detection signal from the metal detection unit 91 at that time, thereby entering the examination room 13 It is determined whether or not there is any metal reaction (SE2). That is, here, since it is assumed that the occupant passes the metal detection unit 91 at the same time that the occupant touches the door knob of the second door 18, almost simultaneously with the acquisition timing of the tag ID 23a in SE1. The determination timing of the metal reaction is determined. However, the determination timing of the metal reaction may be determined by this other method. For example, the metal detector 91 is provided with a human sensor for detecting that a person has passed through the metal detector 90, and this human sensor. The metal reaction may be determined when there is a detection output from the sensor.

  And when there exists a metal reaction (SE2, No), the control part 84 displays the said determination result by the alarm device 60 (SE3), and complete | finishes an entrance / exit management process. Although this display method is arbitrary, for example, the alarm device 60 performs display output such as “cannot bring metal” or audio output. On the other hand, when there is no metal reaction (SE2, Yes), the control unit 84 proceeds to SE4 and performs room entry authority authentication based on the tag ID 23a acquired in SE1, and when it is determined that there is room entry authority ( SE4, Yes), and moves to SE5.

(effect)
As described above, according to the second embodiment, in addition to the condition that the entry authority authentication by the tag ID 23a is cleared, the metal detector 90 allows entry into the examination room 13 on condition that there is no metal reaction. Therefore, it is possible to avoid a situation in which a medical person having authority to enter the room erroneously brings metal while knowing the danger of bringing metal into the examination room 13, and safety can be further improved.

[Embodiment 3]
Next, Embodiment 3 will be described. As in the second embodiment, the third embodiment is not a gate type but a handy type (portable type) when entering / leaving room management is performed using the detection result of the metal detection performed on the occupant. In this embodiment, metal detection is performed using the metal detector 90. However, unless otherwise specified, the configuration and processing shown in the third embodiment are the same as the configuration and processing shown in the second embodiment, and the same contents as the configuration and processing shown in the second embodiment are necessary. Accordingly, the same reference numerals as those used in the description of the second embodiment are used, and the description thereof is omitted.

(Configuration-metal detector)
Similar to the entrance / exit management system 1 according to the second embodiment, the entrance / exit management system 1 according to the third embodiment includes a metal detector 100. This metal detector 100 is a metal detection means for performing metal detection for a person who enters the examination room 13, and is configured as a rod-like body having a length of about 20 cm to 60 cm, for example.

  As shown in the block diagram of FIG. 18, the metal detector 100 includes a metal detection unit 101, a human body communication unit 102, a wireless communication unit 103, and a control unit 104. The metal detection unit 101 uses, for example, electromagnetic induction, and detects the metal by detecting a magnetic field accompanying eddy current generated when the metal passes through the detection coil. The human body communication unit 102 is a human body communication unit that receives the tag ID 23a from the IC tag 20 through human body communication using medical personnel as a medium. The wireless communication unit 103 is a transmission unit that wirelessly transmits a detection signal to the system control device 80. The control unit 104 is a control unit that controls each unit of the metal detector 100, and outputs a detection signal to the system control device 80 via the wireless communication unit 103 when metal is detected by the metal detection unit 101. . Although illustration is omitted, the system control device 80 is also provided with a wireless communication unit that performs wireless communication with the wireless communication unit 103 of the metal detector 100. However, the metal detector 100 and the system control device 80 may be connected by wire, and in this case, the wireless communication unit and the like can be omitted.

(processing)
Next, the entrance / exit management process performed in the control part 84 of this entrance / exit management system 1 is demonstrated. FIG. 19 is a flowchart of the entrance / exit management process. However, SF4 to SF9 in FIG. 19 are the same as SA4 to SA9 in FIG. A medical person who has entered the anterior chamber 12 holds the metal detector 100 disposed in the anterior chamber 12 by hand, and holds the metal detector 100 by itself (and the patient when accompanied by a patient). The metal is detected by holding it around. Thus, when a medical person holds the metal detector 100 by hand, the tag ID 23a is transferred from the human body communication part 21 of the IC tag 20 worn by the medical person to the human body communication part 102 of the metal detector 100. The tag ID 23 a is transmitted by communication, and is wirelessly transmitted to the system management apparatus 80 via the wireless communication unit 103 of the metal detector 100. On the other hand, when the medical staff is not touching the metal detector 100, or when the medical staff is not wearing the IC tag 20, the tag ID 23a is read from the IC tag 20. Therefore, the tag ID 23a is not transmitted from the metal detector 100 to the system management device 80.

  The control unit 84 of the system management device 80 monitors the transmission of the tag ID 23a from the metal detector 100. When the tag ID 23a is transmitted (SF1, Yes), the transmission of the tag ID 23a from the IC tag reading device 30 is performed. Is monitored (SF2). For example, when a medical person who has finished metal detection touches the door knob of the second door 18 to enter the examination room 13, the IC tag 20 is attached to the IC tag 20 of the IC tag 20 worn by the medical person. The tag ID 23a is transmitted to the human body communication unit 31 of the reading device 30 through human body communication, and the tag ID 23a is transmitted to the communication unit 81 of the system management device 80.

  When the tag ID 23a is transmitted from the IC tag reader 30 (SF2, Yes), the room entry authority control unit 84a determines whether the tag ID 23a acquired in SF1 and the tag ID 23a acquired in SF2 are the same. And determining whether there is room entry authority information stored in the room entry authority information table 85a in association with the same tag ID 23a as the tag ID 23a. The presence / absence of entry authority is determined (SF3). Then, only when the tag ID 23a acquired in SF1 and the tag ID 23a acquired in SF2 are identical to each other and it is confirmed that the user has authority to enter the room based on the tag ID 23a (SF3, Yes), SF4. In other cases (SF3, No), the alarm device 60 in SF10 determines that the tag ID does not match or the metal detection has not been completed. The result is displayed and the entrance / exit management process is terminated.

(effect)
As described above, according to the third embodiment, in addition to the condition that the entry authority authentication by the tag ID 23a is cleared, it is possible to enter the examination room 13 on the condition that the person having the entry authority touches the metal detector 100. Therefore, it becomes possible to make the medical personnel authorized to enter the room aware of the use of the metal detector 100, and erroneously bring in the metal while knowing the danger of bringing the metal into the examination room 13. The situation can be avoided and the safety can be further improved.

[III] Modifications to Each Embodiment While the embodiments of the present invention have been described above, the specific configuration and means of the present invention are within the scope of the technical idea of each invention described in the claims. It can be arbitrarily modified and improved within. Hereinafter, such a modification will be described.

  First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved.

(About IC tags)
In each of the above-described embodiments, a medical person having sufficient knowledge about safety and the like is allowed to wear the IC tag 20, and the patient does not need to wear the IC tag 20, and the medical staff who has the authority to enter the examination room However, the IC tag 20 may be attached to the patient. In each of the above embodiments, the tag ID 23a of the IC tag 20 is communicated by human body communication. However, the IC tag 20 is active tag, semi-active tag or UHF band having a non-contact wireless communication function. It may be configured as a passive tag or the like that uses radio waves of the above, or biometric authentication (vein authentication, voiceprint authentication, face authentication, retina authentication, etc.) may be used. However, since the faces and hands of medical personnel are often covered with a mask, gloves, or the like, it is preferable to perform human body communication or non-contact wireless communication rather than biometric authentication.

  Alternatively, even in the case of performing human body communication, communication may be performed through a hand of a medical person or a portion other than the door knob of the second door 18, for example, the arm, elbow, shoulder of the medical person Any one of the head, back, buttocks, legs, etc. may be an electrode disposed in the vicinity of the second door 18 other than the door knob or in the vicinity of the second door 18 (for example, in the vicinity of the second door 18 in the front chamber 12). Communication should be made when the electrode embedded in the floor mat laid on the floor or the electrode embedded under the floor in the vicinity is directly or indirectly contacted via clothes or shoes. May be.

  In each of the above embodiments, the IC tag 20 is configured to be brought into the examination room 13, but it is more preferable that the IC tag 20 is not brought in. Therefore, for example, an IC tag receiving means for placing the IC tag 20 is provided on the side surface of the second door 18 on the front chamber 12 side so that the IC tag 20 is not required to be brought in. The fact that the IC tag 20 is placed in the tag receiving means may be added to the conditions for entrance / exit management. For example, the IC tag receiving means is provided with a communication means for contact communication with the IC tag 20, and when the tag ID 23a is received from the IC tag 20 by contact communication with the IC tag 20, the IC tag reception It is determined that the IC tag 20 is placed on the means. Then, the IC tag receiving means transmits the tag ID 23a acquired in this way to the system control device 80 together with the reception completion signal of the IC tag 20, and the system control device 80 receives the tag ID 23a together with the reception completion signal. In addition, the presence or absence of the room entry authority may be determined based on the received tag ID 23a, and the second door 18 may be unlocked only when the room entry authorization exists. According to such a system, it is possible to reliably prevent the IC tag 20 from being brought in, so that safety can be further improved.

(About intrusion detection devices)
In each of the above embodiments, the intrusion detection devices 40a and 40b have both a function of detecting the presence or absence of an intruder and a function of detecting the state of the first door 15 and the second door 18, Only one of the functions may be provided. For example, in the case of providing only the function of detecting the presence or absence of an intruder, it is confirmed that an intruder into the examination room 13 has been detected and that the intruder's authority to enter the examination room 13 has not been confirmed. As a condition, alarm output is performed.

(Regarding time management)
Moreover, in each said embodiment, you may add the function which manages the medical staff's entrance time to the examination room 13. FIG. For example, the system control device 80 measures the time from when the second door 18 is opened until it is closed, and outputs an alarm via the alarm device 60 when this time exceeds a predetermined time. Thus, it may warn that medical personnel are exposed to a strong magnetic field environment or a radioactive environment for a long time.

(About the first door and the second door)
In each of the above embodiments, it is assumed that the first door 15 and the second door 18 are installed, but each process may be performed on the assumption that only the second door 18 is used. For example, in the intruder detection process, an alarm output is output on the condition that the intruder's passage through the second door 18 is detected and that the intruder's right to enter the examination room 13 cannot be confirmed. You may make it perform. Further, when such processing is performed, the interlock processing may be omitted.
