Description

  The present invention relates to an entrance management system used as a security system.

  As an entry management system that permits entry into a specific area only when the person is authenticated, a system using an ID card reader, a fingerprint collation device, or the like is generally known. However, the entrance management system using these devices cannot prevent, for example, so-called “joint entrance” of an unauthorized person who enters together when the person enters the room.

To solve this problem, a gate zone that can be closed by a pair of doors facing the room and the outside is provided between the inside and outside of the room. The body weight is measured, and the weight measurement data is compared with the registered weight registration data of the resident, and when the difference between the two is within an allowable value, it is determined that the person is the only person. An entrance management system that unlocks the door on the side facing the room and permits entry is disclosed (see, for example, Patent Document 1).
JP-A-6-348974 (paragraphs 0010 to 0012)

  If the weight registration data of the resident who has been registered in advance is not regularly maintained, the difference between the weight measurement data and the weight registration data may be caused by the increase / decrease in the occupant's weight over time, regardless of the person himself / herself. There is a greater possibility that entry will not be allowed due to out of tolerance. In addition, the weight is private information, and when manually registering the weight registration data, women in particular tend to dislike knowing their weight. When the number of people entering the room is large, the manual input operation of each weight registration data becomes difficult, and there is a possibility of an input error or a difference between the reported weight and the actual weight.

  The present invention has been made to solve such a problem, and in an entrance management system having a function of discriminating only the person by weight measurement, the weight registration data is automatically obtained without knowing the weight to others. It is an object of the present invention to provide an entrance management system that can be rewritten and has excellent discrimination characteristics even if the body weight changes with time.

  In order to solve the above-mentioned problem, the present invention is provided with a regulation facility for restricting entry into a specific area room, and the input ID information input from the ID information input means by the resident and the registered resident When it is determined that the person is the person by comparing the registered ID information, and the weight measurement data of the room occupant measured at a predetermined position around the restricted facility and the weight of the room occupant registered in advance. Compared to registered data, when the difference between the two is within an allowable value, the entrance management system that allows entry into a specific area room by deregulating the restriction facility, and newly registering weight registration data In this case, the weight measurement data measured at the predetermined position is automatically registered as weight registration data, and thereafter, the weight registration data for the next entry is based on the weight measurement data measured at the predetermined position when entering the room. Data was entry control system, characterized in that it comprises a weight data registration means for automatically updating registering.

  According to this room entry management system, when newly registering weight registration data, it is not registered manually by a keyboard or the like, but weight measurement data measured at a predetermined position is automatically registered as it is as weight registration data. Therefore, a situation in which one's weight is known to an input person such as a keyboard does not occur. And the problem of an input mistake does not arise, but an actual weight value is registered reliably. In addition, since the weight registration data for the next entry is automatically updated and registered based on the weight measurement data measured at the predetermined position, the latest weight value is always reflected in the weight registration data when entering the room. . Therefore, when the increase or decrease in the weight of the occupants when viewed over the long term is significant, the difference between the weight measurement data and the weight registration data is outside the allowable value even though the person is the person, and entry is not permitted. The frequency of occurrence of erroneous recognition is reduced. In terms of the fact that the latest weight value is always reflected in the weight registration data when entering the room, the allowable value range used for comparison between the weight measurement data and the weight registration data is set narrower than before. As a result, the accuracy of checking by the individual weight becomes more strict.

  Further, the present invention is characterized in that the regulation facility is configured by a gate zone that is interposed between two area chambers and can form a closed space by a pair of doors facing each area chamber, and the predetermined position is an interior of the gate zone. In the entrance management system, the weight measurement data of the occupant is measured in a state where the gate zone is closed.

  According to this room entry management system, it is possible to reliably prevent a roaming person from entering the room together when the person enters the room.

  According to the present invention, it becomes an entrance management system in which the weight is not known to others, and even if the weight changes with time, the discrimination of the person is excellent and the check accuracy based on the individual weight is improved.

  In the following, a description will be given of a case in which a gate zone that is interposed between two area rooms and that can form a closed space with a pair of doors facing each area room is described as a restriction facility for restricting entry into a specific area room. . FIG. 1 is an explanatory plan view around the gate zone, FIG. 2 is a block diagram of the configuration of the entrance management system according to the present invention, and FIG. 3 is a flowchart of the operation of the entrance management system according to the present invention.

  In FIG. 1, reference numeral 1 is provided between two area rooms (inside and outside), a door facing the outside (hereinafter referred to as an entrance side door 2) and a door facing the room (hereinafter referred to as “inside”). This is a gate zone in which a closed space can be formed by the exit side door 3). The gate zone 1 shown in the figure is formed as a space having a substantially circular cross-sectional shape in plan view. An ID information input means (entrance side ID terminal device 5) for inputting the ID information of the occupant himself / herself is attached to the part facing the outdoor side in the casing 4 of the gate zone 1, and the same means is also applied to the part facing the room inside. (Exit side ID terminal device 6) is attached. When entering the indoor side from the outdoor side, the entrance door 2 is automatically opened by an input operation at the entrance side ID terminal device 5, and when entering the outdoor side from the indoor side, the exit side ID terminal device 6 The exit door 3 is automatically opened by the input operation.

  The entrance side door 2 and the exit side door 3 are doors that slide open and close in the lateral direction, and are housed in the housing 4 when opened. Except for maintenance, etc., the entrance person basically does not directly open and close the entrance side door 2 and the exit side door 3 by hand, and as described above, these doors automatically open and close by operation of each ID terminal device. . In this embodiment, the time when these doors are closed is in the locked state, and the time when these doors are opened is referred to as unlocking.

  In FIG. 2, reference numeral 7 denotes a control device that controls each unit so that only authorized persons can enter the room, and is installed in a predetermined place on the indoor side, a remote maintenance room, or a regulation facility. FIG. 1 shows a case where the control device 7 is installed in the housing 4. Connected to the control device 7 is a display device 8 (such as a display screen of a personal computer) that displays registration contents, control contents, and the like mainly during maintenance. Further, the entrance side ID terminal device 5 and the exit side ID terminal device 6 are connected to the control device 7. Examples of the entrance side ID terminal device 5 and the exit side ID terminal device 6 include a numeric key input method for inputting a personal identification number, a card reader method, a fingerprint collation method, an iris collation method, and a palm shape collation method. Is not particularly limited.

  In the present embodiment, the gate-side control unit 9 is connected to the control device 7. This gate-side control unit 9 is provided in the gate zone 1 (inside the casing 4) shown in FIG. 1, and enters and exits the entrance-side door 2 (FIG. 1) and the exit-side door 3 (FIG. 1). The side door opening / closing device 10 and the exit side door opening / closing device 11 are connected. In some cases, the entrance side door opening / closing device 10 and the exit side door opening / closing device 11 may be directly connected to the control device 7 without providing the gate side control unit 9.

  A weight sensor (weight scale) 12 is connected to the gate-side control unit 9. The weight sensor 12 is provided under the floor of the gate zone 1 (FIG. 1). In FIG. 1, when the occupant is located in the measurement area 13 (predetermined position around the regulation facility) in the gate zone 1, The weight of the occupants is measured. When the occupant is protruding from the measurement area 13, a voice is detected so that the occupant is positioned on the measurement area 13 of the weight sensor 12 by detecting the state of being protruded by an area detection sensor, a mat switch, or the like. Announced.

  In FIG. 2, the control device 7 is provided with a non-volatile memory such as a flash memory, and ID information and body weight data of the room occupants are registered in this memory. In the present embodiment, the control device 7 includes ID information (referred to as input ID information) input by the occupant from the entrance side ID terminal device 5 or the exit side ID terminal device 6, and the occupant ID registered in advance in the memory. The gate-side control unit 9 has a function of collating information (referred to as registration ID information), and the weight of the occupant (referred to as weight measurement data) measured in the gate zone 1 (FIG. 1) and the memory in advance. It is configured to have a function of comparing the weight of registered occupants (referred to as weight registration data). With the above configuration, when the input ID information matches the registered ID information and the difference between the weight measurement data and the weight registration data is within the allowable value, the door on the area room side to be entered is opened. It has become. The allowable value for the difference between the weight measurement data and the weight registration data is set by, for example, the gate-side control unit 9. The allowable value is set to an appropriate value, and a numerical value may be set for each individual.

  In the present invention, when newly registering weight registration data in the control device 7, the weight measurement data measured in the gate zone 1 (FIG. 1) is automatically registered as it is as weight registration data. The main feature is that it includes weight data registration means 14 that automatically updates and registers the weight registration data for the next entry based on the weight measurement data measured in the gate zone 1 (FIG. 1). When newly registering the weight registration data, the weight measurement data measured in the gate zone 1 (FIG. 1) is automatically registered as the weight registration data as it is in the control device 7 instead of registering manually by a keyboard or the like. By adopting the configuration, a situation in which one's weight is known to the keyboard input person (administrator) does not occur. Therefore, at this time, even the administrator cannot see the personal weight registration data. For example, of the personal information displayed on the display device 8, only the weight registration data is hidden so that the registration / change of the weight registration data cannot be performed manually by a keyboard or the like.

  Next, the weight registration data for the next entry is automatically updated based on the operation when newly registering the weight registration data and the weight measurement data measured in the gate zone 1 (FIG. 1) when entering the room. The operation in the case of registration will be described with reference to FIG. 3, with reference to FIG. 1 and FIG. The case of entering from the outdoor side to the indoor side will be described as an example. First, the person entering the room inputs ID information, that is, a collation operation indicating that he / she is the person himself / herself using the room ID terminal device 5 (ST1). The room ID terminal device 5 transmits the verification data (input ID information) to the control device 7 (ST2), and the control device 7 verifies the input ID information and the registered ID information (ST3). If the verification does not match (NO), it is determined that the person is not permitted to enter the room, and the process returns to step ST1 again. When the collation matches (YES), the process proceeds to the next step ST4.

  In step ST4, a verification OK signal indicating that the verification has been matched is transmitted from the control device 7 to the entrance side ID terminal device 5, and in response to this, the entrance side ID terminal device 5 sends the entry side door 2 to the control device 7. An unlock request signal for opening is transmitted (ST5). The control device 7 transmits the weight registration data registered in association with the registration ID information of the room occupant together with the unlock request signal to the gate side control unit 9 (ST6). The gate-side controller 9 drives the entry-side door opening / closing device 10 to open the entry-side door 2 (ST7), and after the entrant enters the gate zone 1, the entry-side door 2 is closed (ST8).

  In this embodiment, a known photoelectric sensor is provided in the gate zone 1, and after the step of ST8, it is checked whether or not there is one person in the gate zone 1 by this photoelectric sensor ( ST9). When it is determined that there is not one person (NO), an NG process such as sounding an alarm sound is performed, and when it is determined that there is one person (YES), the process proceeds to the next step ST10.

  In the gate zone 1, the weight of the occupant is automatically measured by the weight sensor 12 (ST10). Then, the gate-side control unit 9 determines whether or not the weight registration data received in step ST6 is 0 kg (ST11). If it is determined that it is 0 kg (YES), the process proceeds to step ST14 described later. To do. The flow on the YES side in the step of ST11 shows a flow in the case of newly registering weight registration data. When it is determined in step ST11 that the weight registration data is not 0 kg (NO), the weight measurement data measured in step ST10 and the weight registration data received in step ST6 are compared in the gate-side control unit 9. (ST12), the process proceeds to step ST13. The flow on the NO side in this step of ST11 shows a flow in the case where the weight registration data for the next entry is automatically updated and registered based on the weight measurement data measured in the gate zone 1 at the time of entry. Yes.

  In step ST13, it is determined whether or not the difference between the weight measurement data and the weight registration data is within the allowable value, and it is determined that the difference is not within the allowable value (that is, the weight is not equal to one person's weight). (NO) When an NG process such as sounding an alarm sound is made and it is determined that the difference is within an allowable value (that is, the body weight is one person's body weight) (YES), the next step of ST14 The exit side door 3 opens. Then, after the person entering the room leaves the gate zone 1, the exit side door 3 is closed (ST15).

  In parallel with the step ST15, the gate-side control unit 9 generates the next weight registration data (the weight registration data for the next entry) based on the weight measurement data measured by the weight sensor 12 (ST16). . Here, as an example of “next weight registration data”, for example, an average value of the weight measurement data and the weight registration data used in the step of ST12 may be mentioned. As another example, a plurality of past weight measurement data may be recorded in the control device 7 or the gate-side control unit 9, and an average value of the latest weight measurement data combined therewith may be used. In operation, the latest weight measurement data itself measured in step ST10 may be “next weight registration data”. In this case, “next weight registration data is generated based on the weight measurement data”. This corresponds to the configuration. The specifications of these “next weight registration data” are appropriately determined mainly by factors such as the entrance interval. In the case of the flow on the YES side in step ST11 described above (when newly registering weight registration data), the specification of “next weight registration data” is the weight measurement data measured in step ST10. .

  Next, the gate-side control unit 9 transmits to the control device 7 the next weight registration data generated in step ST16 and an entry completion signal indicating that the entry person has entered the room (ST17). In the control device 7, a predetermined entry event occurs, and the weight registration data registered in the memory is automatically updated and registered with the next weight registration data transmitted from the gate-side control unit 9 (ST18). .

  As described above, if the weight registration data for the next entry is automatically updated and registered based on the weight measurement data measured in the gate zone 1 when entering the room, the weight registration data for entering the room Will always reflect the latest weight value. Therefore, if the increase or decrease in the weight of the occupants when viewed over the long term is significant, the difference between the weight measurement data and the weight registration data is outside the allowable value even though the person is the person, and entry is not permitted. The frequency of occurrence of misrecognition is reduced, and the system is excellent in the person's discrimination. In terms of the fact that the latest weight value is always reflected in the weight registration data when entering the room, the allowable value range used for comparison between the weight measurement data and the weight registration data is set narrower than before. As a result, the accuracy of checking by the individual weight becomes more strict.

  In addition, as for registration of weight registration data, the case of newly registering and the case of updating registration are performed based on the determination result of whether or not the weight registration data is 0 kg as described in the step of ST11. The control program is also simple.

  Also, when the weight registration data is corrected (cleared) in the middle and newly registered again, the weight is not made known to the person as follows. For example, when correcting the weight registration data, a weight correction (clear) command is transmitted from the personal computer or the like to the control device 7. As a result, the weight registration data registered in the control device 7 is cleared (that is, the weight registration data is set to 0 kg), and then the gate zone 1 is temporarily passed in the same manner as when newly registering the weight registration data. Thus, the weight registration data is automatically re-registered (see the flow on the YES side of step ST11). Therefore, since there is no need for human intervention regarding the correction of the weight registration data, the weight is not known to the manager. During maintenance mainly for trouble and maintenance, the weight registration data and the weight measurement data are displayed on the gate zone 1 side (for example, a display screen provided on the entrance side ID terminal device 5 or the exit side ID terminal device 6). It can be displayed with. In this case, the display may be performed only when the maintenance door (lid) is opened, for example.

  The preferred embodiments of the present invention have been described above. As shown in FIG. 1, the described form is a case where the entrance side ID terminal device 5 and the exit side ID terminal device 6 are provided on the outdoor side and the indoor side, respectively. May be provided in the gate zone 1 as shown in FIG. In this case, for example, when the occupant is positioned in front of the entrance side door 2 on the outdoor side or in front of the exit side door 3 on the indoor side, the entrance side door 2 or the exit side door 3 is opened by a known automatic door sensor. ID information is input in the gate zone 1. This configuration is economical because only one ID terminal device is required for bidirectional traffic between the indoor side and the outdoor side.

  Moreover, this invention is not limited to the gate zone 1 as a regulation installation. For example, FIG. 4 shows an example in which the regulation facility is an entrance door 21 of a room that requires security in an intelligent building or a laboratory. The entrance side ID terminal device 5 is provided in the vicinity of the entrance door 2, and the measurement area 13 for measuring body weight is formed on the floor in front of the entrance door 21. In this example, the input ID information input by the room occupant from the room ID terminal device 5 and the registered ID information of the room occupant registered in advance are collated by the control device 7 (FIG. 2), and the person is the person. And the weight measurement data of the occupant measured in the measurement area 13 are compared with the weight registration data of the occupant registered in advance, and the difference between the two is within an allowable value. At some point, the door 21 is unlocked and entry is permitted. At this time, by appropriately setting the shape and area of the measurement area 13, even if an unauthorized intruder tries to enter the room together, the weight will exceed one person. For example, it is possible to take a measure such as sounding an alarm, and prevent unauthorized persons from entering the room together.

  FIG. 5 shows a case where the regulation facility is a gate device 22 represented by an automatic ticket gate. The entrance side ID terminal device 5 is attached to the main body of the gate device 22, for example, and the measurement area 13 for measuring body weight is formed on the floor in front of the openable gate 22a. In this example, the control device 7 (FIG. 2) collates the input ID information input by the room occupant (passerby) from the room ID terminal device 5 and the previously registered ID information of the room occupant. The weight measurement data of the room occupant measured in the measurement area 13 when the person is determined to be the person is compared with the weight registration data of the room occupant registered in advance, and the difference between the two is determined. When it is within the allowable value, the gate 22a is opened and entry (traffic) is permitted. Even in this case, by appropriately setting the shape and area of the measurement area 13, even if an unauthorized intruder tries to enter the room together, the weight will exceed one person. Thus, for example, it is possible to take measures such as sounding an alarm, and to prevent unauthorized persons from entering the room together.

  The room entry management system of the present invention is not limited to the purpose of entering a room, but can be applied as long as it relates to entry into a specific area (including two-way) via a regulation facility. In other words, in the present invention, entering the room means entering into a specific area or leaving the specific area in a broad sense.
