Description

  The present invention moves to a non-stop floor in an elevator that allows the elevator to move to a non-stop floor by operating a release switch and an operation button on the operation panel in the car installed in the elevator car according to a predetermined operation procedure. The present invention relates to an elevator crime prevention device and an elevator crime prevention method that reduce the possibility of unauthorized release of an elevator non-stop floor by an operation by a person without authority.

  In elevators in residential or office buildings, non-stop floors may be set up for security or privacy reasons. The non-stop floor is a floor where the stop of the elevator is restricted during normal operation. Specifically, the destination button on the non-stop floor is invalidated on the elevator car operation panel, and even when the destination button is pressed, it is not accepted.

  Only persons having the authority to move to the non-stop floor (hereinafter referred to as related persons) such as maintenance managers and building owners can move to the non-stop floor. A person concerned moves an elevator to a target non-stop floor by operating a non-stop floor release switch (hereinafter abbreviated as a release switch) and an operation button on an operation panel in a car installed in the elevator car (hereinafter referred to as a non-stop floor). , Called non-stop floor cancellation). The following is an example of how to cancel a non-stop floor.

  An example of a method for canceling a non-stop floor in a conventional elevator crime prevention device is to provide a release switch on the elevator car operation panel, and insert the key into this release switch to rotate it, so that the destination of the non-stop floor is There is a method for activating a button. This method has an advantage that related parties can be limited to those who own the key (see, for example, Patent Document 1).

  In addition, as another example of a method for canceling a non-stop floor in a conventional elevator crime prevention device, a method for canceling a non-stop floor by operating an operation button on an elevator operation panel in a predetermined procedure. There is. This method has an advantage that related parties can be limited to those who know a predetermined button operation (see, for example, Patent Document 2).

  Further, in a conventional elevator security device, it is detected that the person who does not have the authority to move to the non-stop floor (hereinafter referred to as a third party) attempts to release the non-stop floor illegally (hereinafter referred to as the third party). As an example of a countermeasure method in the case of abbreviated detection of fraud, a method for identifying a criminal by forcibly moving an elevator car to a specific floor where a camera is installed has been proposed (for example, (See Patent Document 3).

Japanese Patent No. 2667573 JP 61-35110 A JP 2005-126224 A

However, the prior art has the following problems.
In the elevator crime prevention device in Patent Document 1, a release switch is used as a method for canceling a non-stop floor. For this reason, when the key is stolen or duplicated, there has been a problem that the cancellation of the non-stop floor is performed illegally. Further, the release switch has a problem that the non-stop floor can be released relatively easily by short-circuiting or opening the release switch wiring on the operation panel in the car.

  Moreover, in the elevator crime prevention apparatus in Patent Document 2, a predetermined button operation is used as a method for canceling the non-stop floor. For this reason, there has been a problem that the non-stop floor is canceled by a person who already knows the predetermined button operation or a person who knows the predetermined button operation illegally through trial and error.

  Furthermore, in the elevator crime prevention device disclosed in Patent Document 3, when unauthorized release is detected, the elevator is forcibly moved to a specific floor. For this reason, there is a problem that the operation cannot be re-executed even if the authorized person simply performs the cancellation operation of the non-stop floor.

  The present invention has been made in order to solve the above-described problems, and there is a possibility that the elevator's non-stop floor may be illegally released by an operation by a person who does not have the authority to move to the non-stop floor. It is an object of the present invention to obtain an elevator crime prevention device and an elevator crime prevention method which are reduced.

  The elevator crime prevention device according to the present invention is an elevator crime prevention device that allows an elevator to move to a non-stop floor by operating a release switch and an operation button on an operation panel in a car installed in the elevator car according to a predetermined operation procedure. The release switch is configured to switch between a “release” state that permits movement of the elevator car to the non-stop floor and a “setting” state that restricts movement to the non-stop floor. A control operation unit that allows the elevator car to move to a non-stop floor by detecting that the operation button has been operated in accordance with a predetermined button operation procedure while maintaining the release switch on the operation panel in the “release” state. It is equipped with.

  The elevator crime prevention method according to the present invention is an elevator crime prevention method that permits an elevator to move to a non-stop floor by operating a release switch and an operation button on an operation panel in a car installed in the elevator car according to a predetermined operation procedure.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of an elevator crime prevention apparatus and an elevator crime prevention method according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected and demonstrated about the part which is the same or it corresponds in each figure.

Embodiment 1 FIG.
FIG. 1 is an illustration of an elevator car operation panel according to the first embodiment of the present invention. An elevator car 1 shown in FIG. 1 includes an in-car operation panel 10. The car operation panel 10 further includes a plurality of destination buttons 11, a door opening button 12, a door closing button 13, and a plurality of release switches 14.

  FIG. 1 is a view of an elevator car 1 as viewed from the inside. The in-car operation panel 10 of the elevator car 1 has a destination button 11 for designating a destination floor to which the operator moves, a door open button 12 and a door close button 13 for opening and closing the door. An operator during normal operation can move the elevator car 1 to a desired destination floor by operating these operation buttons.

  The release switch 14 on the in-car operation panel 10 is used when a related person releases a non-stop floor. This will be described in detail later.

  FIG. 2 is a configuration diagram of an elevator crime prevention device according to Embodiment 1 of the present invention. The elevator crime prevention apparatus shown in FIG. 2 includes an elevator car 1, a control calculation unit 2, and external notification means 3. Here, the elevator car 1 includes an in-car operation panel 10, a car call registration detection means 15, a release switch detection means 16, a car internal control means 17, a door device 18, and an announcement device 19. The car operation panel 10 includes a destination button 11, a door open button 12, a door close button 13, and a release switch 14. Further, the control calculation unit 2 includes a car operation control means 20.

  The actual control of the elevator car 1 is performed by the car operation control means 20 of the control arithmetic unit 2 installed outside the elevator car 1 in accordance with the operation of the in-car operation panel 10.

  The operation of the destination button 11, the door opening button 12 and the door closing button 13 performed by the operator on the operation panel 10 in the car is detected by the car call registration detecting means 15, and the car operation control means 20 of the control calculation unit 2. Is output. Similarly, the operation of the release switch 14 performed by the operator on the in-car operation panel 10 is detected by the release switch detection means 16 and output to the car operation control means 20 of the control calculation unit 2.

  The car operation control means 20 processes the inputs from the car call registration detection means 15 and the release switch detection means 16 according to a preset program.

  As a result, when the door of the elevator car 1 needs to be opened and closed, the car operation control means 20 instructs the car internal control means 17 to open and close the door. When the elevator car 1 needs to be moved, the car operation control means 20 controls the elevator car 1 to move to the destination floor. Further, when it is necessary to send the announcement into the elevator car 1, the car operation control means 20 instructs the car internal control means 17 to send the announcement.

  Further, when the car operation control means 20 detects an abnormality in the elevator, the car operation control means 20 controls the external reporting means 3 to notify an alarm to an external monitoring room or the like.

  The car internal control means 17 opens and closes the door of the elevator car 1 by controlling the door device 18 of the elevator car 1 in accordance with instructions from the car operation control means 20. Similarly, the announcement device 19 is controlled to cause the announcement to flow in the elevator car 1.

  Up to this point, the description has been made centering on the operation of the elevator security device for a general operation when the operator uses a floor other than the non-stop floor, that is, during a normal operation. From here, it demonstrates centering around operation | movement of the crime prevention apparatus of an elevator in case the cancellation operation of a non-stop floor is accompanied.

  As described above, the in-car operation panel 10 includes the release switch 14 for releasing the non-stop floor in addition to the general operation buttons for normal operation. As shown in FIG. 1, the release switch 14 can switch the state between the “release” side and the “setting” side by inserting the key and rotating the key. The state of the release switch 14 is normally on the “setting” side, but when the non-stop floor is released, it is temporarily switched to the “release” side.

  The release switch 14 has two states, a “release” state for permitting the elevator car to move to a non-stop floor and a “setting” state for restricting the stop to the non-stop floor. Anything is acceptable. For example, a springback type release switch 14 can be used.

  With the spring-back release switch 14, the key cannot be removed if the key is rotated to the “release” side, and the key automatically returns to the “setting” side by the spring force when the hand is released. A release switch 14 of the type.

  The advantage of using such a springback type release switch 14 is that it is ensured that the release switch 14 is not on the “release” side when the key is not inserted. As a result, the release switch 14 is not left on the “release” side, so that the possibility of unauthorized release of the non-stop floor by a third party who does not have the key can be reduced. .

  In addition, the arrangement | positioning method of the cancellation | release switch 14 on the operation panel 10 in a car changes with elevators, and the following two types exist mainly. The first type is a type in which the destination button 11 and the release switch 14 are arranged side by side as shown in FIG. In this case, there are as many release switches 14 as there are destination buttons 11.

  The second type is a type in which only one release switch 14 exists on the in-car operation panel 10. In this case, one release switch 14 is shared by all destination buttons 11. Therefore, when canceling a non-stop floor, since the target destination floor is not known only by the release switch 14, the destination button 11 is operated in combination.

  However, even in the first type, in practice, the release switch 14 and the destination button 11 are often operated in combination, and there is no significant difference in operation between the two. Therefore, in the following description of the present invention, both are generally handled without distinction. However, if there is a need to distinguish between them, they will be explained each time.

  The non-stop floor release method in the first embodiment is operated in combination with the destination button 11, the door open button 12, and the door close button 13 in conjunction with the operation of the release switch 14 on the in-car operation panel 10. Is a technical feature. Therefore, a specific method for canceling the non-stop floor will be described below.

Elevator non-stop floor is released in the following three steps.
[First Stage] The operator inserts a key into the release switch 14 of the target floor and rotates it to change the state to the “release” side.
[Second Stage] The operator operates the operation buttons on the in-car operation panel 10 according to a predetermined operation procedure.
[Third Stage] The operator returns the release switch 14 to the “setting” side.

  When the springback type release switch 14 is used, the final third step can be omitted because it is automatically performed by releasing the key. The operator need only take care to maintain the release switch 14 on the “release” side during button operation. As described above, by using the springback type release switch 14, the operability of releasing the non-stop floor is improved, and an operation error can be reduced.

  In the following description, the operation at the second stage is referred to as “predetermined button operation”, and the operations at the first stage and the third stage are both referred to as “predetermined release switch operation”.

  The “predetermined button operation” may be anything as long as it is not easily conceivable by a third party. For example, a combination of “simultaneous press”, “sequential press”, “long press” and “timing” of the operation buttons can be selected according to the purpose. Some specific examples are introduced below.

  First, an example using “simultaneous pressing” is given. In this case, for example, the operator may press the door open button 12 and the door close button 13 simultaneously. However, this operation procedure is effective only with the above-described first type release switch 14 (a type placed next to the destination button 11). In the case of the second type release switch 14 (shared type), it is necessary to specify the target destination floor. For example, instead, the target destination button 11 and the door closing button 13 are pressed simultaneously. That's fine.

  Next, an example using “order push” is given. In this case, for example, the operator may press the target destination button 11 after pressing the door closing button 13.

  Next, an example using “long press” is given. In this case, for example, the operator may press and hold the destination button 11 of the target non-stop floor for 2 seconds or longer.

  Next, an example using “timing” is given. In this case, for example, the operator may press the destination button 11 on the target non-stop floor after 5 seconds or more have passed since the release switch 14 is set to the “release” side. Alternatively, it may be within 5 seconds instead of 5 seconds or more.

  Next, an example in which “long press” and “timing” are combined will be described. In this case, for example, the operator may press and hold the destination button 11 of the target non-stop floor for 2 seconds or more after 5 seconds or more have passed since the release switch 14 is set to the “release” side. .

  Next, an example in which all of “simultaneous pressing”, “order pressing”, “long pressing” and “timing” are combined will be given. In this case, for example, the operator simultaneously presses the door open button 12 and the door close button 13 within 5 seconds after the release switch 14 is set to the “release” side, and further presses the target destination button 11 for 2 seconds. What is necessary is just to make it press long.

  As described above, there are as many “predetermined button operations” as combinations of “simultaneous press”, “sequential press”, “long press”, and “timing” of the destination button 11, the door open button 12 and the door close button 13. And there is great freedom. For this reason, it is difficult for a third party to decipher the procedure, and it is possible to reduce the possibility that a third party who does not know the “predetermined button operation” will illegally cancel the elevator non-stop floor.

  Next, the operation when unauthorized release is detected will be described. In order to detect fraud cancellation, it is necessary to first consider what kind of operation is considered fraudulent. In the present invention, fraudulent operations can be defined relatively easily. In other words, if the “predetermined button operation” is wrong, it may be determined that fraud cancellation has been detected.

  It should be noted that the case where the release switch 14 is returned to the “setting” side before the operator finishes the “predetermined button operation” can be included when the above “predetermined button operation” is wrong. .

  When detecting the unauthorized release, the control calculation unit 2 causes an announcement such as “operation is illegal” to flow into the elevator car 1 using the announcement device 19. As a result, it is possible to give a warning when a third party tries to release the non-stop floor illegally, and when a related person only makes an operation mistake, the user can prompt the correct operation again.

  FIG. 3 is a flowchart showing a series of processes for canceling the non-stop floor in the first embodiment of the present invention. Hereinafter, the non-stop floor cancellation method will be described in detail with reference to FIG.

  In the flowchart of FIG. 3, only the process related to the non-stop floor cancellation operation will be described. Other than this, for example, processing of general operations during normal operation can be handled as an independent process separately, and thus is not particularly described in FIG. Note that switching of these processes can be performed from, for example, an interrupt routine that processes a change in the state of the release switch 14.

  In step S <b> 1 of FIG. 3, first, the control calculation unit 2 checks whether or not a “predetermined release switch operation” has been performed by an operator in the elevator car 1. Specifically, the operator inserts a key into the release switch 14 of the target floor, rotates it, and checks whether or not the release switch 14 is set to the “release” side.

  When the “predetermined release switch operation” is performed in step S1, the control calculation unit 2 proceeds to step S2. On the other hand, if the “predetermined release switch operation” has not been performed, the control calculation unit 2 continues to wait for the “predetermined release switch operation” to be performed in step S1.

  Next, in step S <b> 2, the control calculation unit 2 checks whether the “predetermined button operation” has been performed by the operator.

  Here, a specific example of the “predetermined button operation” check process in step S2 will be introduced. FIG. 4 is a flowchart showing an example of “predetermined button operation” in the first exemplary embodiment of the present invention.

  The flowchart shown in FIG. 4 represents step S2 in FIG. 3 as a function. However, it is not a general function, but merely intended to show a specific example. In FIG. 4, the button operation using the “long press” exemplified above is used as the “predetermined button operation”. That is, the function of FIG. 4 checks whether the operator has pressed the destination button 11 of the target non-stop floor for 2 seconds or longer.

  First, in step S21, the control calculation unit 2 checks whether the destination button 11 has been pressed by the operator. Note that the timeout process in step S22 is to prevent the process from going into an infinite loop when no button operation is performed.

  If the destination button 11 is pressed in step S21, the control calculation unit 2 proceeds to step S23. On the other hand, if the destination button 11 is not pressed in step S21, that is, if an operation button other than the destination button 11 is pressed or if no operation button is pressed and a time-out occurs in step S22, the control calculation unit 2 determines that the “predetermined button operation” has not been correctly performed, and proceeds to step S25. Then, “NO” is set as the return value of the function, and the process returns to step S2.

  Next, in step S23, the control calculation unit 2 checks whether the destination button 11 is continuously pressed for 2 seconds or more by the operator. In step S23, when the destination button 11 is pressed for 2 seconds or longer, the control calculation unit 2 determines that “predetermined button operation” has been performed, and proceeds to step S24, where “YES” is set as the return value of the function. Is set and the process returns to step S2.

  On the other hand, if the destination button 11 is not pressed for 2 seconds or longer in step S23, the control calculation unit 2 determines that the “predetermined button operation” has not been performed correctly, and proceeds to step S25. Then, “NO” is set as the return value of the function, and the process returns to step S2.

  Next, in step S3, the control calculation unit 2 checks the return value of the function (that is, the return value set by finishing the series of processes in FIG. 4). If the return value of the function is “YES” in step S3, the control calculation unit 2 determines that the cancellation of the non-stop floor has been performed normally, and proceeds to step S4. In step S4, the control calculation unit 2 releases the non-stop floor and moves the elevator car 1 to the target non-stop floor.

  On the other hand, if the return value of the function is “NO” in step S2, the control calculation unit 2 determines that unauthorized cancellation has been detected, and in step S5, the control calculation unit 2 To announce.

  In the above description, as the “predetermined button operation”, a button operation in which the destination non-stop floor destination button 11 is pressed for 2 seconds or longer is used. However, this “predetermined button operation” can be changed later by making the portion corresponding to the flowchart of FIG. 4 rewritable in the control program of the control arithmetic unit 2.

  Thus, by making it possible to change the setting of the “predetermined button operation”, it is possible to increase the crime prevention property of the method for canceling the non-stop floor and further enhance the flexibility of key operation. For example, if the owner of a building has changed but it takes time to collect the key, it can be handled by simply changing the “predetermined button operation”.

  In addition, as described above, as a method of releasing the elevator non-stop floor, by using the release switch 14 on the in-car operation panel 10 and the “predetermined button operation”, one of the methods is the third method. Even if it is illegally used by a person, it is possible to reduce the possibility that the elevator stoppage is canceled illegally.

  As described above, according to the first embodiment, as a method of canceling the elevator non-stop floor, the cancel switch operation on the elevator car operation panel and the cancel operation by a predetermined button operation are used in combination. The button operation can be changed. Accordingly, it is possible to obtain an elevator crime prevention device and an elevator crime prevention method that reduce the possibility that the elevator's non-stop floor will be illegally released by an operation by a person who does not have the authority to move to the non-stop floor.

  In the above description, the “predetermined button operation” for releasing the non-stop floor is common to all the non-stop floors, but can be set for each non-stop floor. By doing in this way, the crime prevention property of the non-stop floor cancellation method and the flexibility of key operation can be further enhanced.

  Moreover, in the above description, the control calculation part 2 made the announcement of unauthorized operation only once, when unauthorized cancellation | release was detected (step S5 of FIG. 3). However, for example, it is possible to make announcements multiple times. It is also possible to repeat announcements for a certain period.

Embodiment 2. FIG.
In the first embodiment, it is assumed that the “predetermined button operation” should not be easily conceived by a third party. However, even if the “predetermined button operation” is simple, there is a possibility that the cancellation of the non-stop floor may be performed improperly if a third party does not give a trial and error to release the non-stop floor. Can be reduced. Therefore, in the second embodiment, a method for restricting the cancellation of the non-stop floor from being trial and error by a third party will be described.

  The coping method in the case of detecting fraud cancellation in the second embodiment must take balance into consideration. For example, on the one hand, it is necessary to restrict the release of the stop floor from being illegally trial-and-error by a third party, but on the other hand, in the event that the stop floor release operation is mistaken, There is a need to start over.

  As a method for this, when a fraud release is detected, a grace time (hereinafter, abbreviated as a predetermined grace time) for allowing the operation to be repeated for a certain period of time may be provided. If a correct operation is not performed again within this grace period, an alarm is issued to an external monitoring room or the like.

  FIG. 5 is a flowchart showing a series of processes in the case where fraud cancellation is detected in the second embodiment of the present invention. FIG. 5 is obtained by adding the following three processes to the flowchart of FIG.

  The first additional process includes a timer and measures an elapsed time from the time when the unauthorized release is first detected. As a result, the time during which a third party can trial and error the cancellation of the non-stop floor is limited within a predetermined grace period. Furthermore, even if a related person makes a mistake in the operation for canceling the non-stop floor, it can be redone within the predetermined grace period.

  In the second addition process, the door of the elevator car 1 is not opened when the unauthorized release is detected. Furthermore, if correct operation is not performed again within a predetermined grace period, an alarm is reported to an external monitoring room or the like.

  The third additional process uses a timer release operation, so even if the person concerned makes a mistake in the cancellation operation for the non-stop floor and cannot remember the release operation for the non-stop floor, this timer release is performed within a predetermined grace period. By performing the operation, the door of the elevator car 1 is opened so that the elevator car 1 can be escaped.

  As the timer release operation, an operation procedure combining “predetermined release switch operation” and “predetermined button operation” described in the description of the non-stop floor release method can be used. However, it must be different from the non-stop floor cancellation method. Specifically, for example, an operation procedure in which the door opening button 12 is pressed while the release switch 14 is set to the “release” side can be employed.

  The above three additional processes will be specifically described with reference to the flowchart of FIG. Note that steps S1 to S5 in FIG. 5 are the same as steps S1 to S5 in FIG. Therefore, the description of FIG. 5 is performed from step S6.

  If unauthorized cancellation is detected in the process before step S5, in step S6, the control calculation unit 2 controls the car internal control means 17 so that the door of the elevator car 1 is not opened.

  Next, in step S7, the control calculation unit 2 starts a timer operation. Specifically, the control calculation unit 2 uses a timer to start measuring the elapsed time after detecting fraud cancellation. Note that this step S7 is performed only once when unauthorized removal is detected for the first time.

  Next, in step S8, the control calculation unit 2 checks whether or not the operator has performed a timer cancellation operation. As described above, the timer canceling operation is for the person concerned to give up canceling the non-stop floor and escape from the elevator when the “predetermined button operation” is forgotten.

  In step S8, when the operator performs a timer release operation, the control calculation unit 2 stops the timer operation in step S11. Further, in step S12, the door of the elevator car 1 is opened. As a result, the operator can escape from the elevator car 1.

  On the other hand, if the operator does not perform the timer release operation in step S8, the control calculation unit 2 checks in step S9 whether or not a predetermined grace period has elapsed since the first unauthorized release was detected. To do.

  In step S9, if the predetermined grace time has elapsed, the control calculation unit 2 reports an alarm in step S10 notifying the external monitoring room or the like that an unauthorized operation has been performed. On the other hand, when the predetermined grace time has not yet elapsed, the process returns to S1 and the check for the cancellation operation of the non-stop floor is repeated.

  As described above, according to the second embodiment, the timer is provided, and the elapsed time from the time when the illegal release is first detected is measured. As a result, the time during which a third party can trial and error the cancellation of the non-stop floor is limited within a predetermined grace period. Furthermore, even if a related person makes a mistake in the operation for canceling the non-stop floor, it can be redone within the predetermined grace period.

  In addition, if correct operation is not performed again within a predetermined grace period, an alarm is sent to an external monitoring room so that a third party trapped in the elevator car 1 can be caught. Yes.

  Furthermore, by using the timer canceling operation, even if the person concerned makes a mistake in the canceling operation of the non-stop floor and can not remember the canceling operation of the non-stop floor, by performing this timer canceling operation within a predetermined grace period, The door of the elevator car 1 is opened so that the elevator car 1 can be escaped.

  In the above description, when the operation for canceling the non-stop floor is illegally performed, the control calculation unit 2 plays the announcement of the illegal operation only once (step S5 in FIG. 5). However, for example, it is possible to make announcements multiple times. It is also possible to repeat announcements for a certain period. Furthermore, it is also possible to notify announcements periodically until the timer is released.
