Description

  The present invention relates to an elevator control device and an elevator system, and in particular, an elevator control device and an elevator that can cope with an elevator user getting off from a car on a floor other than the floor that is allowed to get on and off the car. The present invention relates to an elevator system including a control device.

  For example, as described in Patent Documents 1 and 2 below, systems that allow users of buildings and condominiums to carry IC tags are widespread from the viewpoint of improving security performance and service performance of buildings and condominiums.

  When this system is applied to the elevator operation control of buildings and condominiums, the operation information necessary for operating the elevator (for example, name information of the elevator user, elevator) The floor information that the user is allowed to get on and off from the car is recorded, a signal including this operation information is transmitted from the IC tag, and the signal transmitted from the IC tag is received by the receiving unit. When the signal transmitted from the IC tag is received at the receiving unit, the elevator is controlled based on the operation information included in the received signal.

  When the receiving unit receives the signal transmitted from the IC tag, the floor on which the elevator user is allowed to get on and off the car is determined based on the operation information included in the signal. For this reason, if the elevator user who boarded the car has designated the destination floor in the car, the car is designated if the designated floor is allowed to get on and off. Go to the elevator floor on the first floor. On the other hand, when the destination floor designated by the elevator user is a floor that is not permitted to get on and off, the car does not move to the elevator landing on the designated floor.

  The same can be said when a landing call is made at the elevator landing. When the elevator user makes a landing call at the elevator landing on the floor where entry / exit is allowed, the car moves to the elevator landing according to the landing call. On the other hand, when the elevator user makes a landing call at the elevator landing on the floor where entry / exit is not permitted, the car does not move to the elevator landing.

Thus, by controlling the elevator operation based on the operation information included in the signal transmitted from the IC tag, it is possible to prevent a suspicious person from entering and exiting each floor using the elevator, The security performance of buildings and condominiums can be improved.

  However, in the system using the above-described IC tag, the following points are not considered.

  When there are a plurality of elevator users in the car, the car sequentially stops at the floor where each elevator user is about to get off. For this reason, some elevator users may get out of the car by mistake when the car stops on a floor other than the target floor that they are trying to get off.

  If the floor that was accidentally dismounted is a floor that is not allowed for the elevator user to get off, even if the elevator user makes a landing call at the elevator landing, the car will not be on that floor. The elevator user does not come and is left in the elevator landing on the floor where he / she gets off, and cannot move from the floor when he / she gets off.

  The present invention has been made to solve the above problems, and its purpose is to rescue an elevator user from the floor when the elevator user gets off when the elevator user accidentally gets off the floor that is not allowed to get on and off. There is.

  In the elevator control device, the first control unit receives a signal from an IC tag carried by an elevator user in a car, and receives the signal from an IC tag carried by an elevator user at the elevator hall. A second receiving unit, a clock unit that measures the time that the elevator user stops at the elevator platform, based on a reception result of the second receiving unit, and an elevator user is allowed to get on and off the elevator platform from the elevator platform A use floor determination unit that determines whether or not the vehicle is operated, a measurement result of the clock unit, a determination result of the use floor determination unit, and a reception result of the first reception unit, and And a rescue signal generation unit that generates a rescue signal to be moved to the landing.

  ADVANTAGE OF THE INVENTION According to this invention, when an elevator user gets off to the floor which is not permitted to get on and off the car, the elevator user can be rescued by moving the car to the floor.

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

(First embodiment)
As shown in FIG. 1, the elevator control apparatus according to the first embodiment of the present invention includes a plurality of IC tag readers 2a, 2b, 2c, and 2d that receive signals from the IC tag 1 carried by each elevator user. A rescue control unit 3 to which the IC tag readers 2a, 2b, 2c and 2d are connected, an alarm 4 and a display 5 connected to the rescue control unit 3, and an elevation control unit 6 connected to the rescue control unit 3. I have. Further, the elevator control apparatus includes a main control unit (not shown) that comprehensively controls the IC tag readers 2a, 2b, 2c, and 2d, the rescue control unit 3, the alarm 4, the display 5, and the elevation control unit 6. Is provided.

  The IC tag 1 is an IC chip in which operation information necessary for operating the elevator (for example, name information of the elevator user, floor information that the elevator user is allowed to get on and off the car 7) is recorded. And an antenna for transmitting operation information in the IC chip. The IC tag 1 includes an active tag that incorporates a battery for transmitting operation information in the IC chip, and a passive tag that obtains electric power necessary for transmission by causing electromagnetic induction from an externally transmitted radio wave. As the IC tag 1 of the first embodiment, any method can be adopted. In addition, various information other than operation information necessary for operating the elevator, for example, personal information such as bank credit information may be recorded in the IC tag 1.

  The IC tag readers 2a and 2b are installed in a car 7 (see FIG. 2), and function as a first receiving unit that receives signals from the IC tag 1 carried by an elevator user in the car 7. The IC tag readers 2c and 2d are installed in the elevator hall 8 (see FIG. 2) on each floor, and function as a second receiving unit that receives signals from the IC tag 1 carried by an elevator user at the elevator hall 8.

  The elevator according to the present embodiment is a floor that can be designated as a destination floor by the elevator user, and a floor from which the elevator user can make a landing call is the elevator user that the IC tag readers 2a, 2b, 2c, and 2d receive. Is regulated by a signal from the IC tag 1 carried by the user. Specifically, when an elevator user who gets in the car 7 designates a destination floor, the floor that is permitted to get on and off included in the signal from the IC tag 1 received by the IC tag readers 2a and 2b. When the floor matches the designated destination floor, the car 7 moves to the designated floor. Further, when a landing call is made at the elevator hall 8, the floors allowed to get on and off included in the signal from the IC tag 1 received by the IC tag readers 2c and 2d, and the elevator hall 8 that made the landing call. The landing call becomes valid when it matches the floor with the floor, and the car 7 moves to the elevator landing 8 on the floor where the landing call is made.

  For this reason, if the elevator user gets off the car 7 at a floor other than the floor that is allowed to get on and off, even if he / she makes a landing call at the elevator landing 8 on that floor, Is not valid and the car 7 does not move to that floor.

  The rescue control unit 3 includes a first recording unit 9, a second recording unit 10, a clock unit 11, a use floor determination unit 12, and a rescue signal generation unit 13.

  The first recording unit 9 records the signal from the IC tag 1 received by the IC tag readers 2a and 2b together with the received time data as a boarding history. The record of the boarding history is performed every predetermined time (for example, every several seconds) or whenever the car 7 stops on each floor. From the boarding history of the first recording unit 9, it can be confirmed that a certain elevator user carrying the IC tag 1 has been in the car 7 at a certain time.

  The second recording unit 10 records the signal from the IC tag 1 received by the IC tag readers 2c and 2d together with the received time data. This recording is performed every predetermined time (for example, every several seconds). Based on the contents recorded in the second recording unit, it can be confirmed that a certain elevator user carrying the IC tag 1 was in the elevator hall 8 on a certain floor at a certain time. When the elevator user stays at the elevator hall 8 on a certain floor for a long time, the signal from the IC tag 1 carried by the elevator user is repeatedly received by the IC tag readers 2c and 2d, and the second recording unit 10 receives the signal. Recorded repeatedly.

  The clock unit 11 measures the stop time in which the elevator user is at the elevator hall 8. The measurement of the stop time is performed by measuring the time until a signal from one IC tag 1 is recorded in the second recording unit 10 and no signal from the same IC tag 1 is recorded in the second recording unit 10. Is called. The measurement time by the clock unit 11 becomes longer as the stopping time for the elevator user at the elevator hall 8 becomes longer.

  Based on the signal from the IC tag 1 received by the IC tag readers 2c and 2d, the usage floor determination unit 12 allows the elevator user who carries the IC tag 1 to the floor where the IC tag readers 2c and 2d are installed. It is determined whether or not getting on and off the elevator car 8 from the elevator platform 8 is permitted. This determination is made, for example, by whether or not the floor that is permitted to get on and off included in the signal received from the IC tag 1 matches the floor where the elevator platform 8 where the elevator user carrying the IC tag 1 is located is. Is done. If they match, it is determined that entry / exit is allowed, and if they do not match, it is determined that entry / exit is not allowed.

  The rescue signal generator 13 first gets the elevator user into and out of the car 7 based on the measurement result of the clock unit 11, the determination result of the use floor determination unit 12, and the recording result of the first recording unit 9. It is determined whether or not the passenger gets off from the car 7 by mistake on the floor that is not permitted. If the elevator user at the elevator hall 8 determines that the elevator user has mistakenly got off the car 7 at a floor other than the intended floor, the elevator user A rescue signal is generated for moving the car 7 to the elevator landing 8 on the floor where the passenger got off by mistake.

  In the determination in the rescue signal generation unit 13, the clock unit 11 measures that the elevator user has stopped at the elevator platform 8 for a set time (for example, 1 minute), and the elevator user has the elevator platform 8 The use floor determination unit 12 determines that it is not permitted to get on and off the car 7 from a certain floor, and the car is used until the elevator user immediately before (measurement is started by the clock unit 11). If it can be confirmed from the boarding history of the first recording unit 9 that the user has been on board 7, it is determined that the elevator user has accidentally got off the car 7 on a floor other than the intended floor. .

  The generated rescue signal is transmitted to the lift control unit 6 that moves the car 7 up and down. When the rescue signal is transmitted, the elevator control of the elevator car 7 is performed by the elevator controller 6, and the elevator car 8 is moved to the elevator landing 8 on the floor where the elevator user who got off accidentally exists.

  The alarm 4 and the display 5 are provided at the elevator hall 8 on each floor. The alarm 4 and the display 5 function as a notification unit that notifies an elevator user who has erroneously got off when a rescue signal is generated. An alarm sound is generated from the alarm 4 and a message such as “Please wait for a while.

  In the elevator control device according to the first embodiment, the case where the alarm 4 and the display 5 serving as a notification unit are provided in the elevator hall 8 has been described as an example. May be added to By providing the notifying unit in the manager room, the manager can confirm the presence of the elevator user who gets off the floor that is not allowed to get on and off the car 7.

  The rescue of the elevator user by the elevator control device according to the first embodiment is performed as shown in the flowchart of FIG. 3 under the control of the rescue control unit 3. The flowchart shown in FIG. 3 assumes that the elevator user A carrying the IC tag 1 is in the car 7 and the elevator user A gets off the car 7 on the floor B. .

  First, a signal from the IC tag 1 carried by the elevator user A in the car 7 is received by the IC tag readers 2a and 2b in the car 7 (S1). The signal from the IC tag 1 received by the IC tag readers 2a and 2b is recorded in the first recording unit 9 together with the received time data (S2).

  When the elevator user A gets off the floor 7 from the car 7, the signal from the IC tag 1 carried by the elevator user A is received by the IC tag readers 2c and 2d provided on the floor B ( S3). The signal from the IC tag 1 received by the IC tag readers 2c and 2d on the floor B is recorded in the second recording unit 10 together with the received time data (S4). Recording in the second recording unit 10 is performed every predetermined time (for example, every several seconds). For this reason, when the stop time in which the elevator user A is at the elevator hall 8 becomes long, the signal from the IC tag 1 carried by the elevator user A is repeatedly received by the IC tag readers 2c and 2d, and the received signal is the second signal. It records on the recording part 10 one after another.

  When the signal from the IC tag 1 is recorded in the second recording unit 10, the time required for the elevator user A to stop at the elevator landing 8 is measured by the clock unit 11 (S5). This measurement is the time from when the recording of the signal from the IC tag 1 of the elevator user A is started until the recording of the signal from the same IC tag 1 is stopped, that is, the elevator user who has come to the elevator hall 8 This is done by measuring the time until A leaves the elevator hall 8.

  After the measurement by the clock unit 11 is started, it is determined whether or not the measurement result of the clock unit 11 has reached a set time (for example, 1 minute) (S6).

  As an example of the case where the measurement time reaches the set time (YES in S6), the elevator user A returns to the car 7 again because the elevator user A accidentally gets off at the floor B that is not the target floor. A case where the vehicle stops at the elevator hall 8 and tries to get on, and the stop time reaches a set time. In addition, even if the floor B that is alighted is the target floor, it stops at the elevator platform 8 for some reason, for example, because it met an acquaintance at the elevator platform 8, and the stopping time reaches the set time. Sometimes.

  On the other hand, when the floor B where the passenger gets off is the target floor, the elevator user A who gets off the vehicle quickly leaves the elevator platform 8, so the measurement by the clock unit 11 does not reach the set time (S6). NO), it can be determined that the generation of the rescue signal is unnecessary, and the control for rescue ends.

  When the measurement result of the clock unit 11 reaches the set time (YES in S6), the elevator user A who gets off at the floor B is allowed to get on and off the elevator car 8 from the elevator landing 8 on the floor B. It is determined in the use floor determination part 12 whether it has been performed (S7). If the elevator user A is allowed to get on and off the elevator car 8 from the elevator landing 8 on the floor B (YES in S7), it can be determined that the generation of the rescue signal is unnecessary, Control for this is completed.

  As an example of the case where the elevator user A is not permitted to get on and off the elevator car 8 from the elevator hall 8 of the floor B (NO in S7), the floor B that is not the floor intended by the elevator user A In case of getting off by mistake.

  If the elevator user A is not permitted to get on and off the elevator car 8 from the elevator hall 8 on the floor B (NO in S7), whether or not it is immediately after the elevator user A gets off the car 7 Is determined (S8). Whether the elevator user A has just got off the car 7 is determined by referring to the boarding history of the elevator user A recorded in the first recording unit 9. As an example of a case where a long time has passed since the elevator user A got off the car 7 (NO in S8), after the elevator user A finished some work on the floor B, the elevator user A entered the elevator hall 8 The case where it came can be mentioned, and it can be determined that the generation of the rescue signal is unnecessary rather than getting off at the floor B by mistake, and the control for the rescue is completed.

  Based on the determinations in steps S6, S7, and S8, it is determined that the measurement result of the clock unit 11 has reached the set time (YES in S6), and the elevator user A gets on and off the elevator car 8 from the elevator landing 8 on the floor B. If it is determined that this is not permitted (NO in S7) and it is determined that the elevator user A is immediately after getting off the car 7 (YES in S8), the elevator user A is in the car 7 The rescue signal generator 13 generates a rescue signal for moving the car 7 to the elevator landing 8 on the floor B. (S9). Further, the rescue signal generator 13 generates a first notification signal for driving the alarm 4 and a second notification signal for driving the display 5. (S10).

  The first notification signal generated in the rescue signal generation unit 13 is transmitted to the driver of the alarm 4 and the second notification signal is transmitted to the driver of the display 5 to drive the alarm 4 and the display 5 (S11). The elevator user A is informed that the car 7 for the car moves to the floor B. The alarm 4 gives a sound for notifying that the rescue car 7 is moved to the floor B, and the display 5 is a display for notifying that the rescue car 7 is moved to the floor B. (For example, “Please wait for a while. The car will come.”) Is performed.

  The rescue signal generated by the rescue signal generation unit 13 is transmitted to the lift control unit 6, and the elevator 7 is lifted and controlled by the lift control unit 6 that has received the rescue signal, so that the car 7 moves to the floor B. (S12).

  In such a configuration, if the elevator user accidentally gets off to a floor other than the intended floor of the elevator user and is not allowed to get in and out of the car 7, the elevator user erroneously From the elevator landing 8 on the floor where you get off, you cannot make a landing call.

  Therefore, in the elevator control apparatus according to the first embodiment, it is determined whether or not the elevator user at the elevator hall 8 has mistakenly got off the floor that is not allowed to get on and off the car 7. However, when it is determined that the user has got off the vehicle accidentally, the rescue signal generator 13 generates a rescue signal. The generated rescue signal is transmitted to the lift control unit 6, and the rescue signal is transmitted to the lift control unit 6, so that the car 7 is driven up and down, and the car 7 is placed on the floor where the elevator user got off by mistake. Moving. Elevator users who get off accidentally on floors that are not allowed to get on and off can get into the car 7 that was moved for rescue and can rescue elevator users who got off accidentally from that floor. .

  Therefore, when an elevator user accidentally gets off at a floor other than the intended floor of the elevator user and is not allowed to get on and off the car 7, the floor where the elevator user got off the wrong passenger The situation where the elevator user is left behind on the floor where he / she got off accidentally can be prevented.

(Second Embodiment)
The basic configuration of the elevator control device according to the second embodiment of the present invention is the same as that of the elevator control device according to the first embodiment. The difference between the elevator control device of the second embodiment and the elevator control device of the first embodiment is the type of signal generated by the rescue signal generation unit 13.

  As shown in the flowchart of FIG. 4, a rescue signal is generated in the rescue signal generator 13 based on the determination results of steps S6, S7, and S8 (S9). Further, in addition to the generation of the rescue signal, the rescue signal generation unit 13 designates an empty car in which the elevator user is not on board as the car 7 that moves to the elevator landing 8 on the floor B for rescue. Is generated (S9-1). Then, a means for designating an empty car as a car 7 that moves to the elevator hall 8 on the floor B for rescue is executed.

  Further, the rescue signal generation unit 13 generates a landing call invalid signal that invalidates the landing call for the car 7 after moving to the elevator landing 8 on the floor B for rescue (S9-2). And here, the means for invalidating the call registration for the car 7 after moving to the elevator landing 8 on the floor B for rescue is executed.

  Further, in the rescue signal generation unit 13, the car 7 after moving to the elevator landing 8 on the floor B for rescue is designated as a specific floor (for example, a floor with an administrator room, a floor with an entrance / exit). A forced movement signal for forced movement is generated (S9-3). Then, means for forcibly moving the car 7 after moving to the floor B for rescue to the specific floor is executed.

  In the present invention, the elevator user A can be rescued by the determination in steps S6, S7, and S8, but the elevator user A may be a suspicious person. This 2nd Embodiment assumes the case where the elevator user A used as rescue object is a suspicious person, and the elevator user A who is a suspicious person and other elevator users are for rescue. We are trying not to get in the car 7.

  Specifically, the car 7 that is moved to the floor B in order to rescue the elevator user A is regarded as an empty car that the elevator user is not on. As a result, the car 7 on which a certain elevator user is boarding moves to the elevator landing 8 on the floor B, and the elevator user A who may be a suspicious person gets into the car 7. Can be prevented.

  Furthermore, the landing call to the car 7 after moving to the floor B in order to rescue the elevator user A is invalidated. For this reason, the car 7 on which the elevator user A, who may be a suspicious person, is moving toward the specific floor stops at the elevator hall 8 on a certain floor and stops. The situation where an elevator user gets in 7 can be prevented.

  Furthermore, by restricting the behavior of the elevator user A who may be a suspicious person by moving the car 7 that rescues the elevator user A to a specific floor regardless of the intention of the elevator user A Can do.
