Description

  The present invention relates to an elevator security system incorporated in a building such as a building, and more particularly to an elevator security system using various cards individually owned by each user of the elevator.

  For buildings such as buildings where companies, various organizations, and research laboratories are located, the entire building is strictly protected for the purpose of preventing the contents of work from leaking to the outside and preventing the intrusion of suspicious individuals. Security measures (security measures for crime prevention) are taken. In addition to entering the building from the outside, even within the building, even if it is an employee of the same company, each floor cannot be moved freely. This is even more so if there are multiple companies in a building on each floor. Therefore, it is necessary to take strict security measures (safety measures for crime prevention) even for an elevator as a transportation system connecting the floors of the building.

In the “elevator registration device” described in Patent Document 1, an antenna is attached to an elevator hall and an antenna is also installed in an elevator car, and a user who carries a tag storing destination floor information is provided. When approaching, the destination information stored in the tag is read by the antenna, and the registration of the call to the read destination floor is automatically performed to the elevator control device. Therefore, the user who carries the tag does not need to operate the hall call button at the elevator hall, and further needs to operate the car call button for specifying the destination floor in the car even after getting into the elevator car. There is no.
JP 2005-255320 A

  However, even if the technique of the “elevator registration device” described in Patent Document 1 is applied to the security measures for elevators, the following problems arise.

  That is, because the destination floor information is stored in a tag possessed by each user who enters and exits the building, each user needs a dedicated tag for the elevator. In addition, when a user uses two buildings that implement security measures using this tag, it is necessary to have a dedicated tag for each building. And it is necessary to use each tag properly for each building, which is very troublesome.

  Also, in order to use tags in common in multiple buildings, it is necessary to secure a destination floor area for each building in the tag storage area by matching with security system developers. It was. In addition, when the storage areas used in the tags overlap, special measures such as correction of software are required.

  In addition, since the destination floor information is stored in the user area (area that can be rewritten by the system developer) in the tag storage unit, the data in the tag (destination floor) may be inadvertently rewritten. It was also possible to duplicate this tag with malicious intent.

  The present invention has been made in view of such circumstances, and various cards used for various purposes carried by each user can be used as they are without any modification. It is an object of the present invention to provide an elevator security system that can further improve the security level without having to carry a tag or card dedicated to security.

  In order to solve the above problems, in the elevator security system of the present invention, the car is moved and controlled according to the hall call operation in the hall call registration device on each floor of the elevator and the car call operation in the car call registration device in the car. Call operation acceptance prohibition control means for prohibiting reception of hall call operation and car call operation in the normal state for the elevator control unit, and a unique ID which is set at the time of manufacture and cannot be rewritten and erased regardless of the usage form Is installed in the platform and car on each floor of the elevator, and a usage condition table that stores a plurality of cards of the same standard in which the ID is stored, a floor that can be used by a user who possesses the card of the unique ID for each unique ID A plurality of card readers that read the unique ID stored in the card by the user's contact operation or holding operation of the card. And a floor reading means for reading the available floor corresponding to the unique ID read by each card reader from the usage condition table, and a hall call operation specifying the available floor read by the floor reading means And an acceptance prohibition canceling means for instructing the elevator controller to cancel the prohibition of acceptance of the car call operation.

  In the elevator security system configured as described above, the usage condition table can be used by the user who possesses the card with the unique ID for each unique ID stored in each card carried by each user. Remember the floor. Therefore, a user who carries a card in which a unique ID and a usable floor are stored in the use condition table can go to the floor set for the unique ID of the self card in the use condition table.

  The use floor of the user is not a card possessed by the user but is stored in the use condition table on the elevator side, so that the security of the building is not lowered.

  In another invention, when the unique ID read by the card reader provided at the hall on each floor of the elevator is stored in the use condition table, the hall at the floor provided with the card reader reading the unique ID Unconditional prohibition canceling means for instructing the elevator control unit to unconditionally cancel the hall call operation acceptance prohibition in the call registration device.

  This can prevent the situation where the car is locked in the building because the car cannot be called again by the landing call registration device when the user gets off the car other than the floor. .

  In another invention, the monitoring means for monitoring the operation state of each card reader and the car call in the car call registration device provided in the car when the monitoring means detects an abnormality of the card reader in the car. When the first failure countermeasure means for instructing the elevator control unit to cancel the registration operation acceptance prohibition and the monitoring means detect an abnormality of each card reader provided at the landing on each floor, the card reader And a second failure countermeasure means for instructing the elevator control unit to cancel the hall call registration operation acceptance prohibition in the hall call registration device on the floor provided.

  In such a configuration, when the card reader breaks down, it is possible to prevent itself that the user cannot move at all.

  In another aspect of the invention, there is provided selection setting means for selecting and setting in advance whether or not the first failure countermeasure means can be executed. In the case where stricter security is required, if the card reader breaks down, it will wait until the repair of the failure is completed.

  In another invention, when a registration instruction is stored in the use condition table for the unique ID read by the card reader, the registration mode for shifting the operation mode of the elevator control unit to the registration mode. The transfer card and the destination floor designated by the car call operation in the car call registration device for the unique ID of the new card read by the card reader during this registration mode period can be used by the holder of the new card As a new floor, a new card registration means for writing in the use condition table together with the read unique ID is provided.

  In the elevator security system configured as described above, the unique ID of the card and the use floor can be easily registered in the use condition table when starting to use the new elevator in the building.

  In the present invention, it is possible to use various cards used for various purposes originally carried by each user without any modification, and the elevator user needs to carry tags and cards dedicated for elevator security. In addition, the security level can be further improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic view showing an entire elevator system in which an elevator security system according to an embodiment of the present invention is incorporated.

  A hoisting machine 4 and a drive unit 5 for driving and controlling a motor incorporated in the hoisting machine 4 are provided in a machine room 3 on the upper side of a hoistway 2 provided in a building 1 such as a building. A car 7 is suspended from one end of the main rope 6 hung on the hoisting machine 4, and a counterweight 8 is suspended from the other end. In the car 7, as shown in FIG. 2 (b), a car call registration device 9 and a card reader 10 are attached at positions close to the door 11.

  As shown in FIG. 2C, the car call registration device 9 is provided with a plurality of destination floor buttons 12, an open button 13a, and a close button 13b. Each destination floor button 12 includes an LED that lights the entire button when the destination floor is called and registered. Furthermore, the destination floor button 12 is provided with an operation reception lamp 14 for the destination floor button 12 for the corresponding floor.

  When the operation reception lamp 14 is off, the operation of the destination floor button 12 by the user 15 who has entered the car 7 is not accepted, and the user 15 cannot go to the floor of the destination floor button 12. When the operation reception lamp 14 is lit, the operation of the destination floor button 12 by the user 15 who has entered the car 7 is accepted, and the user 15 can go to the floor of the destination floor button 12.

  On the other hand, as shown in FIG. 2A, a hall call registration device 17 and a card reader 18 are attached to the elevator hall on each floor of the building 1 near the door 16.

  The car call registration device 9 and the hall call registration device 17 on each floor are connected to an elevator control unit 19 composed of a computer provided in the machine room 3 via a signal line. The elevator control unit 19 rotates the hoisting machine 4 via the drive unit 5 based on the calls registered by the car call registration device 9 and the landing call registration devices 17, thereby moving the car 7 to the hoistway 2. The movement is controlled to the destination floor designated by the call.

  Further, the card reader 10 provided in the car 7 and each card reader 18 provided on each floor are connected to a security control unit 21 comprising a computer directed into the machine room 3 via signal lines 20a and 20b, respectively. Has been.

  In a normal state, the security control unit 21 performs a hall call operation by the user 15 in each hall call registration device 17 and a car call operation in the car call registration device 9 in the car 7 with respect to the elevator control unit 19. Reception is prohibited. Therefore, in the normal state, the user 15 who does not have the card 22 cannot use this elevator.

  Next, each user 15 who uses the elevator of the building 1 possesses, and when each user 15 uses the elevator, the card 22 that touches or holds the card reader 10, 18 is used with reference to FIG. I will explain. This card 22 is a variety of IC cards used for various purposes carried by each user 15, and as shown in FIG. 3A, an antenna 23, a communication unit 24, a control unit (CPU) 25, reading and writing. The circuit 26, the storage unit 27, and the power supply circuit 28 are included.

  In this card 22, for example, a unique unique ID 29 set for manufacturing and shipping by a manufacturing company, such as a MAC address of a PC (personal computer) or the like, is stored in the storage unit 27 as shown in FIG. Is set. Even if the unique ID 29 is a card 22 manufactured by a different manufacturing company, the same unique ID 29 is not set. The card 22 is electronic money, a prepaid ticket card that is charged with a boarding fee in transportation, a point card issued by various mass retailers, or the like. Although variable data that is frequently rewritten is stored in the main storage area of the storage unit 27 of the card 22, the unique ID 29 is set so as to be non-rewritable and erasable regardless of the above-described usage patterns.

  FIG. 4 is a schematic configuration diagram of each of the card readers 10 and 18. In the card readers 10 and 18, a transmission request for the unique ID 29 is transmitted to the card 22 via the communication unit 30 that exchanges various information with the security control unit 21, the control unit (CPU) 31, and the antenna 32. A unique ID reading unit 33 that reads the unique ID 29 transmitted from the card 22, an LED 34 that informs the user 15 who owns the card 22 of the availability result for the destination floor from the security control unit 21, a buzzer 35, and A power supply circuit 36 is provided.

  In the control unit (CPU) 31, a unique ID transmission unit 31a that is formed on the application program and transmits the read unique ID 29 to the security control unit 21 is provided. The available output unit 31b lights the LED 34 in “green” for a certain period of time based on the available result received from the security control unit 21 and drives the buzzer 35 with a “beep” sound. On the other hand, the unusable output unit 31c turns on the LED 34 in “red” for a certain period of time based on the unusable result received from the security control unit 21 and drives the buzzer 35 with a “buzzy” sound. Further, the operation confirmation response unit 30d returns a response signal in response to the operation confirmation signal received from the security control unit 21.

  In the card 22 and the card readers 10 and 18, when the user 15 brings the card 22 into contact with the antenna 32 of the card readers 10 and 18 or holds it over, the card reader 10 or 18 sends a transmission request for the unique ID 29 to the card 22. Sent to. The control unit 25 of the card 22 that has received the transmission request for the unique ID 29 reads the unique ID 29 from the storage unit 27 and returns it to the card readers 10 and 18. The unique ID transmission unit 31a of the card reader 10 or 18 that has received the unique ID 29 from the card 22 transmits this unique ID 29 to the security control unit 21 via the communication unit 30 and the signal lines 20a and 20b.

  FIG. 5 is a block diagram illustrating a schematic configuration of the security control unit 21 including a computer. A communication IF (interface) 37 for exchanging various information via the card reader 10 and the signal line 20a in the car 7, and various information exchange via the card reader 18 and the signal line 20b provided at each landing. A communication IF (interface) 38 to be implemented and a communication IF (interface) 39 for sending various commands to the elevator control unit 19 are provided.

  In addition, a use condition table 41, an input buffer 42, and the like are formed in the storage device 40 such as an HDD. In the use condition table 41, as shown in FIG. 6, for each unique ID 29 stored in the various cards 22 possessed by each user 15, the user 22 possessing the card 22 can use. The floor is registered.

  For example, for the user 15 with the unique ID 29 of [0A00017], the first floor which is the reference floor of the building 1 and the fourth floor which is the destination floor are set. Further, the first floor and the third and fifth floors, which are the target floors, are set for the user 15 with the unique ID 29 of [0A04040].

  The card 22 with the unique ID 29 of [0A00014] is a card possessed by the manager of this building (building 1), and “registration” is set for the unique ID 29 of [0A00014] of this card. That is, the card 22 possessed by this manager is placed on the floor where the manager of this building (building 1) executes the unique setting of the unique ID 29 and the use floor, the change of the setting contents, and the deletion with respect to the use condition table 41. use. Specifically, as shown in FIG. 5, the new setting unit 44, the update unit 45, and the deletion unit 46 in the use condition registration unit 43 formed on the application program execute these processes.

  The unique ID input unit 47 provided in the security control unit 21 sends the unique ID 29 read by the card readers 10 and 18 input via the communication IFs 37 and 38 to the registration determination unit 48. The registration determination unit 48 determines whether or not the input unique ID 29 is registered in the use condition table 41 of FIG. If it is not registered in the use condition table 41, the unusable response unit 49 sends the unusable result to the card readers 10 and 18 that have read this unique ID 29 via the communication IFs 37 and 38.

  As a result, as described above, the card readers 10 and 18 illuminate the LED 34 in “red” for a certain period of time, and drive the buzzer 35 with a “buzzy” sound. Notify that it cannot be used.

  On the other hand, when the input unique ID 29 is registered in the use condition table 41, the available response unit 50 can use the card reader 10 or 18 that has read the unique ID 29 via the communication IFs 37 and 38. Send the result.

  As a result, as described above, the card readers 10 and 19 illuminate the LED 34 in “green” for a certain period of time, drive the buzzer 35 with a “beep” sound, and go to the destination floor for the user 15. Notify that it is possible.

  Further, when the input unique ID 29 is registered in the use condition table 41, the operation reception instruction unit 51 performs a call operation specifying the use floor set for the unique ID 29 in the use condition table 41. A command to cancel acceptance prohibition is sent to the elevator control unit 19.

  The elevator control unit 19 prohibits the call operation in which the use floor specified in the use condition table 41 in the car call registration device 9 or the hall call registration device 17 adjacent to the card reader 10 or 19 that has read the unique ID is designated. Release. In the car call registration device 9, the operation reception lamp 14 of the destination floor button 12 that is released from the call operation prohibition, as shown in FIG. Therefore, the user 15 can go to the destination floor by pressing the destination floor button 12 whose operation reception lamp 14 is lit.

  The in-car card reader operation monitoring unit 52 transmits a confirmation signal to the card reader 10 in the car 7 at a constant period, and when the no-response count from the card reader 10 reaches the limit count in the no-response counter 54, If the security release flag 53 is set, a call registration operation prohibition release instruction for the car call registration device 9 is sent to the elevator control unit 19 via the communication IF 39.

  In addition, the hall card reader operation monitoring unit 55 provided for the card reader 18 on each floor transmits a confirmation signal to the card reader 18 on the corresponding floor at a constant period, and no response is received from the card reader 18. When the number of times reaches the limit number in the no answer counter 56, a call registration operation prohibition release instruction to the hall call registration device 17 on the corresponding floor is sent to the elevator control unit 19 via the communication IF 39.

  As described above, when each card reader 10, 18 is abnormal, the call registration operation prohibition for the car call registration device 9 and the hall call registration device 17 corresponding to the card reader 10, 18 in which the abnormality has occurred is canceled and used. The person 15 makes the elevator available unconditionally.

  When stricter security is required, by canceling the security release flag 52, if the card reader 10 breaks down, the user 15 waits until the repair of the failure is completed. .

  The security control unit 21 configured in this manner performs security management processing according to the flowchart shown in FIG.

  When the unique ID 29 of the card 22 read from each of the card readers 10 and 18 is input to the unique ID input unit 47 via the communication IFs 37 and 38 (step S1), the registration determination unit 48 searches the use condition table 41. (S2) If the unique ID 29 is not registered in the use condition table 41 (S3), the unusable response unit 49 sends the unusable result to the card readers 10 and 18 that read the unique ID 29. (S4).

  When the unique ID 29 is registered in the use condition table 41 (S3) and this unique ID 29 is read by the card reader 18 installed at the landing (S5), the available response unit 50 The usable result is sent to the card reader 18 that has read the unique ID 29 (S6). Further, the operation reception instruction unit 51 sends a command for canceling the operation reception prohibition of the hall call registration device 17 on the floor to the elevator control unit 19 so that the user 15 can operate the hall call registration device 18. (S7). Therefore, the user 15 can get into the car 7 at the landing on the corresponding floor.

  In this case, even if the usage floor stored in the usage condition table 41 of the input unique ID 29 and the installation floor of the card reader 18 that has read this unique ID 29 do not match, the installation floor of the card reader 18 that has been read. The call registration operation of the hall call registration device 17 is enabled. As described above, when the user 15 gets off the floor other than the user floor by mistake, the car cannot be called again by the landing call registration device 17, so that the situation where the car is confined in the building 1 occurs. This is to prevent this in advance.

  When the entered unique ID 29 is read by the card reader 10 in the car 7 (S8), when the use floor is set (S9) instead of "registration" designation for this unique ID 29 (S9), an available response The unit 50 sends an available result to the card reader 10 that has read the unique ID 29 (S10). Then, a call operation reception prohibition release command designating the use floor set for the unique ID 29 in the use condition table 41 is sent to the elevator control unit 19, and the car call registration device 9 in the car 7 The destination button 12 on the use floor can be operated (S12). As a result, the user 15 getting into the car 7 can go to the destination floor by pressing the destination button 12 of the car call registration device 9.

  When the card reader 10 in the car 7 reads the input unique ID 29 (S8), and when "registration" is designated for this unique ID 29 (S9), the use condition registration unit 43 is activated and the building The registration (new setting, change, deletion) processing shown in FIG. 8 is executed for the use condition table 41 by the administrator of (building 1) (S13).

  In FIG. 8, when registration (new setting, change, deletion) processing for the use condition table 41 is started, the own operation mode and the operation mode of the elevator control unit 19 are shifted to the “registration mode” (Q1). In this state, when a unique ID 29 is separately input from the same card reader 10 (Q2), the input unique ID 29 is temporarily stored in the input buffer 42 (Q3).

  When the destination floor button 12 of the car call registration device 9 is pressed (Q4), the floor of the destination floor button 12 is written into the input buffer 42 (Q5). Then, one or more floors (use floors) are written in the input buffer 42, and after a predetermined time (Δt) has elapsed (G6), when the open button 13a is pressed (Q7), the new setting unit 44 is activated. The new setting unit 44 sets the combination of the unique ID 29 and each floor (usage floor) written in the input buffer 42 in the new area of the usage condition table 41 shown in FIG. 6 (Q8).

  When the close button 13b is pressed instead of the open button 13a (Q9), the update unit 45 is activated. The update unit 45 rewrites each use floor corresponding to the unique ID 29 written in the input buffer 42 in the use condition table 41 shown in FIG. 6 to each floor (use floor) written in the input buffer 42 (update). (Q10).

  Further, for example, when the combination button operation of the open button 13a and the destination floor button 12 on the specific floor is input (Q11), the deletion unit 46 is activated. The deletion unit 46 deletes the unique ID 29 written in the input buffer 42 in the use condition table 41 shown in FIG. 6 and each use floor corresponding to this unique ID 29 (Q12).

  When the registration (new setting, change, deletion) processing for the use condition table 41 is completed, the registration mode described above is canceled (Q13), and the processing returns to the security management processing operation of FIG.

  In this way, the manager of the building (building 1) has already possessed each user 15 in the presence of each user 15 of this building when starting to use the elevator of the building 1 newly. After the card 22 is brought into contact with or held over the card reader 10 in the car 7, the unique ID 29 and the use floor can be registered in the use condition table 41 by simply pressing the destination floor button 12 on the use floor.

  Further, the car card reader operation monitoring unit 52 in FIG. 5 performs a monitoring process for a failure of the card reader 10 in the car 7 according to the flowchart shown in FIG.

For example, every time a fixed time ΔT ₀ such as 5 seconds elapses (R1), an operation confirmation signal is transmitted to the card reader 10 in the car 7 via the communication IF 37 (R2). When the response signal is received (R3) within the allowable time Δt ₁ (Δt ₁ <ΔT ₀ ) from the card reader 10 (R3), the count value n of the no answer counter 54 is cleared to “0” (R4), Return to R1.

If the response signal is not received even after the allowable time Δt ₁ has elapsed from the card reader 10 (R5), the count value n of the no answer counter 54 is updated (n = n + 1) (R6). If the count value n of the updated does not reach the limit number N _E is (R7), it returns to R1. If the count value n of the updated reaches the limit number N _E (R7), the card reader 10 is judged to be faulty.

  If the security release flag 53 is set to “1” (R8), all the destination floor buttons 12 of the car call registration device 9 are made operable (R9). Then, the abnormality occurrence information is transmitted to, for example, a building management room (R10). Therefore, when the card reader 10 breaks down, the user 15 can go to all the floors. If the security release flag 53 has been released to “0” (R8), nothing is done and a failure recovery is awaited.

  Further, the hall card reader operation monitoring unit 55 in FIG. 5 performs a monitoring process for the failure of the card reader 18 on each floor according to the flowchart shown in FIG.

For example, every time a fixed time ΔT ₀ such as 5 seconds elapses (U1), an operation confirmation signal is transmitted to the hall card reader 18 via the communication IF 38 (U2). When the response signal is received (U3) within the allowable time Δt ₁ (Δt ₁ <ΔT ₀ ) from the card reader 18 (U3), the count value n of the no answer counter 56 is cleared to “0” (U4), Return to U1.

Even if the allowable time Δt ₁ has elapsed from the card reader 18 (U5), if no response signal is received, the count value n of the no answer counter 56 is updated (n = n + 1) (U6). If the count value n of the updated does not reach the limit number N _E is (U7), it returns to U1. If the count value n of the updated reaches the limit number N _E (U7), the card reader 18 is judged to be faulty. Then, the operation of the hall call registration device 17 on the corresponding floor is enabled unconditionally (U8). And abnormality occurrence information is transmitted to the management room of a building, for example (U9). Therefore, when the card reader 18 breaks down, the user 15 can get into the car 7 from the landing without the card 22.

  Therefore, in the elevator security system of the embodiment configured as described above, the various cards 22 used for various purposes carried by each user 15 can be used in this security system as they are without any modification. . Therefore, the elevator user 15 does not need to carry a tag or card dedicated to elevator security.

  Furthermore, since the information on the floor used is not stored in the card 22 possessed by the user 15, the security level can be further improved.
