Abstract

PROBLEM TO BE SOLVED: To suppress occurrence of a secondary disaster and to rescue a passenger quickly, when a situation has been detected where a passenger confined in a car cannot perform a button operation even after elapse of certain time.SOLUTION: A rescue operation device for an elevator includes: a sensor (31) for detecting presence/absence of a passenger in a car; and a door control unit (13) for performing opening/closing control of a door according to an operation input from a control board (21) and an open/closed state of the door. When the door is in a closed state, and operation input is not performed even in a state where a passenger is detected to be present in the car and first specified time elapses, the door control unit moves the door in an open direction by only a minute movement amount. After that, when it is determined that an operation input is performed from the control board before second specified time elapses, the door control unit switches an operation mode of the elevator to a normal operation mode, and performs an operation according to the operation input.

Description

  The present invention relates to an elevator rescue operation apparatus and an elevator rescue operation method for rescuing a passenger trapped in an elevator car.

  When a disaster occurs, after the elevator is landed on the evacuation floor or the nearest floor and the rescue operation is performed, the elevator is generally in a door-closed state for safety. Here, when a passenger who has escaped from the elevator car enters a confined state when the elevator enters a door-closed dormant state, a countermeasure is required.

  Therefore, when the elevator car completes the rescue operation and enters the door-closed state on the predetermined floor, it is determined whether or not there is a passenger who has escaped from the elevator car, and the passenger who has escaped operates the door open button. There is a conventional technique provided with means for forcibly opening the door when the door opening button is not operated even after a predetermined time has elapsed (for example, see Patent Document 1).

  There has also been proposed an elevator rescue operation device that can rescue passengers quickly and safely without waiting for the arrival of an elevator restoration worker when passengers are trapped in the elevator car (for example, , See Patent Document 2).

  In Patent Document 2, a landing button and a rescue operation switch for switching the elevator from a normal operation to a predetermined rescue operation are installed at a landing such as the lowest floor of the elevator. Then, when the elevator is switched to the rescue operation by the rescue operation switch, a predetermined operation is performed on the landing button, thereby releasing the braking of the hoisting machine by the brake device and raising or lowering the car. Making it possible.

However, the prior art has the following problems.
The technique disclosed in Patent Document 1 avoids a pseudo confinement state by forcibly opening the door. As such a pseudo confinement state, for example, a situation is conceivable in which a child is confined in a cage with a finger held between the doors of the center opening. In such a situation, the child cannot move in the vicinity of the entrance without removing his / her finger, and cannot move to the position where the door opening button is located, so that the child is confined without pressing the door opening button.

  However, even if it is possible to detect a state in which a child is trapped in a pseudo manner, it is impossible to accurately grasp the situation where the child is actually pinched. Therefore, as in Patent Document 1, if the door is suddenly fully opened, there is a possibility that a secondary disaster such as scuffing, falling over, or being caught in a door pocket may occur.

  Moreover, in the technique disclosed in Patent Document 2, a rescue operation from the landing side is indispensable, and there is a possibility that it takes time to rescue a trapped passenger.

  The present invention has been made in order to solve the above-described problems. When a passenger trapped in a car detects a situation in which a button cannot be operated even after a predetermined time, a secondary disaster is caused. It is an object of the present invention to obtain an elevator rescue operation device and an elevator rescue operation method that can quickly rescue passengers while suppressing the occurrence of the vehicle.

  An elevator rescue operation apparatus according to the present invention is an elevator rescue operation apparatus for rescue of a passenger trapped in a car, a sensor for detecting whether there is a passenger in the car, and an operation by a user A door control unit that controls the opening and closing of the door according to the operation input from the panel and the detection result of the door opening and closing state. If it is determined that there is no operation input from the operation panel even after the first predetermined time set in advance has passed, the elevator operation mode is changed to the rescue mode. After changing, moving the door in the opening direction by a small amount of movement that the passenger cannot go out of the car, and moving in the opening direction in the rescue mode, the second specified time set in advance If it is determined that there is no operation input from the operation panel even after passing, the second is notified to the outside that the confinement abnormality has occurred and moved in the opening direction in the rescue mode. When it is determined that there has been an operation input from the operation panel before the specified time elapses, the operation mode of the elevator is switched to the normal operation mode, and the operation according to the operation input is performed.

  The elevator rescue operation method according to the present invention includes a sensor for detecting whether or not there are passengers in a car, an operation input from the operation panel by the user, and a door opening / closing state according to a detection result of the door opening / closing state. An elevator rescue operation method for use in an elevator rescue operation device for rescue a passenger confined in a car, the door control unit, in the door control unit, in the closed state, When it is determined that there is a passenger in the car from the detection result of the sensor, and it is determined that there is no operation input from the operation panel even if the state determined that there is a passenger passes the preset first specified time. Changes the elevator operation mode to the rescue mode, and moves the door in the opening direction by a minute amount that the passenger cannot go out of the car, and the first step. If it is determined that there is no operation input from the operation panel even after the preset second specified time has elapsed after the door is moved in the opening direction by the If it is determined that there is an operation input from the operation panel before the second specified time elapses after the door is moved in the opening direction by the second step and the first step, A third step of switching the operation mode to the normal operation mode and performing an operation according to the operation input.

  According to the present invention, without suddenly moving the door to the fully open position, the door is moved in the opening direction by a predetermined minute movement amount, and a process for performing an appropriate process in accordance with the passenger's operation thereafter is executed. Of an elevator that can quickly rescue passengers while suppressing the occurrence of secondary disasters when a passenger trapped in the car detects a situation in which buttons cannot be operated even after a certain period of time. A rescue operation apparatus and an elevator rescue operation method can be obtained.

It is a front view which shows the rescue operation apparatus of the elevator in Embodiment 1 of this invention. It is a block diagram of the rescue operation apparatus of the elevator in Embodiment 1 of this invention. It is the flowchart which showed the rescue operation processing procedure by the rescue operation apparatus of the elevator in Embodiment 1 of this invention.

  Hereinafter, preferred embodiments of an elevator rescue operation apparatus and an elevator rescue operation method of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a front view showing an elevator rescue operation apparatus according to Embodiment 1 of the present invention. FIG. 2 is a block diagram of the elevator rescue operation apparatus according to Embodiment 1 of the present invention. The elevator shown in FIG. 1 illustrates the case where the door (door) is a double-open type. FIG. 1 shows a state in the car, and the illustration on the landing side is omitted because it is not directly related to the technical features of the present application.

  In FIG. 1, the elevator rescue operation apparatus includes a car apparatus unit 10, an in-car display system unit 20, and a sensor unit 30.

  The car apparatus unit 10 includes a door mechanism 11 having a door 1 that opens and closes an elevator doorway, an doorway column 2, an doorway frame 3, a door driving unit 12 that operates the door 1, and a door control unit that controls the door driving unit 12. 13. Although not shown, the door 1 includes a car door that is provided in the car and opens and closes the car doorway, and a landing door that is provided in the hall and opens and closes the landing doorway. Then, with the car door and the landing door engaged with each other, the car door opens and closes the car doorway, so that the landing door opens and closes the hall doorway.

  The in-car display system unit 20 includes an operation panel 21 and an operation panel control unit 22 that controls input / output of the operation panel 21. Here, the operation panel 21 is mounted in an elevator car, and is provided with a destination button and a door opening / closing button.

  Next, the human sensor 31 constituting the sensor unit 30 is installed in the entrance / exit frame 3 of the door mechanism 11 of the entrance / exit provided with the door 1, the entrance / exit post 2, and the entrance / exit frame 3. The human sensor 31 detects the presence or absence of a passenger in the vicinity of the door 1 by emitting light from between the door 1 and the entrance / exit frame 3 toward the entrance / exit of the elevator.

  The role of the human sensor 31 is to detect a state in which a passenger is present near the door 1 when the door 1 is closed. Accordingly, it is sufficient that such a state can be detected directly or indirectly, and if this purpose can be achieved, the type of sensor or the mounting position of the sensor is not limited to the contents exemplified in the first embodiment. Specifically, a non-contact pinching detection sensor or a mechanical pinching detection sensor can be used as a substitute for the human sensor 31, and the pinching state can be directly detected.

  The door control unit 13 acquires the detection result of the human sensor 31 and the operation input information from the operation panel 21 via the operation panel control unit 22. When the door 1 is in the closed state, the door control unit 13 detects that the user 40 is in the vicinity of the door in the car by the human sensor 31 and when the operation by the operation panel 21 is not performed for a certain period of time. It can be determined that there is a possibility that the user 40 in the car is trapped in the car without being able to operate the operation panel 21 for some reason.

  Here, the “some reason” means, for example, that the finger of the user 40 has been sandwiched between the doors 1 or the user has fallen and lost consciousness. As an example, a situation where the user cannot operate is described.

When such a situation is detected, the door control unit 13 according to the first embodiment is technically characterized in that it shifts the control mode from the normal operation mode to the rescue mode and performs the following control operation. .
(Control action 1) Although the user 40 cannot go out of the car, the door 1 is opened in the opening direction by a minute movement amount ΔL (e.g., corresponding to several centimeters) that can eliminate the pinched state of the finger or the like. Move.

(Control Operation 2) When the operation panel 21 is operated by the user 40 after the control operation 1 is performed, the operation mode is returned to the normal operation mode, and the control according to the operation content is executed. For example, when the open button is operated, the user 40 can get off by making the door 1 fully open, and when any destination floor is operated, the door 1 is opened. After the fully closed state, it will move to the target destination floor.

(Control Operation 3) Even after the execution of the control operation 1, the presence of the user 40 in the vicinity of the door in the car is detected by the human sensor 31 and the operation by the operation panel 21 is not performed for a predetermined time. In that case, the door control unit 13 pauses the elevator and reports an abnormal state to the outside.

  It is also conceivable to allow the following further opening / closing control before performing the control operation 3. Even after the control operation 1 is performed, if the human sensor 31 detects that the user 40 is in the vicinity of the door in the car and the operation by the operation panel 21 continues for a certain period of time, the minute movement It is also possible that the pinched state has not been eliminated by simply moving it in the opening direction by the amount ΔL. For example, there may be a case where clothes, luggage, or the like are intricately entangled with the door 1 or a case where a pull-in occurs between the door 1 and the entrance / exit post 2. In the following description, such a state is referred to as a door interference state.

  Therefore, as the control operation 3 ′ before performing the control operation 3, the user cannot go out of the car, but in order to eliminate the door interference state, the minute movement width ΔW (for example, 10 cm at the maximum from the closed state). It is also conceivable that the door 1 can be opened and closed via the operation panel 21 in a range in which the door 1 can be moved in the opening direction.

  Even though the opening / closing movement of the minute movement width ΔW is permitted, it is detected by the human sensor 31 that the user 40 is in the vicinity of the door in the car and the operation by the operation panel 21 is not performed for a certain period of time. When the operation continues, the door control unit 13 performs the control operation 3, stops the elevator, and notifies the outside of the abnormal state.

  Next, a series of operations of the elevator rescue operation apparatus according to the first embodiment will be described using a flowchart. FIG. 3 is a flowchart showing a rescue operation processing procedure by the elevator rescue operation apparatus according to Embodiment 1 of the present invention. Specifically, a series of operations performed by the door control unit 13 based on the detection result from the human sensor 31 and the operation contents of the operation panel 21 acquired via the operation panel control unit 22 are shown.

  First, in step S301, the door control unit 13 reads the detection state of the human sensor 31 after controlling the door to the closed state. In step S302, the door control unit 13 detects that the user 40 is in the vicinity of the door in the car by the human sensor 31, and if the operation by the operation panel 21 is not performed for a predetermined time, Is determined to have occurred, and the process proceeds to step S303.

  On the other hand, in step S302, the door control unit 13 detects that the user 40 is not detected in the vicinity of the door in the car by the human sensor 31, or if the operation by the operation panel 21 is within a certain time. Therefore, it is determined that there is no need to switch to the rescue mode, and the series of processes is terminated while maintaining the normal operation mode.

  When the process proceeds to step S303, the door control unit 13 switches the operation mode to the rescue mode. Further, in step S304, the door control unit 13 moves the door 1 in the opening direction by the minute movement amount ΔL (corresponding to the control operation 1). By this movement processing, when a finger or the like is pinched between the doors 1, the user 40 can cancel the pinched state and can freely move in the car and operate the operation panel 21. It becomes possible.

  Furthermore, the amount ΔL at which the door 1 is opened is limited to a value at which the user 40 cannot go out of the car. As a result, the user 40 falls to the landing side or interferes with a person waiting on the landing side by the door opening operation in Step S304 (that is, the door opening operation performed without being based on the operation of the user 40). The occurrence of secondary disasters such as these can be prevented.

  Next, in step S305, the door control unit 13 determines whether or not the operation panel 21 has been operated by the user 40 after the door 1 is moved in the opening direction by the minute movement amount ΔL. When the operation panel 21 is operated by the user 40, the door control unit 13 proceeds to the process of step S306, restores the normal operation mode, and ends the series of processes (corresponding to the control operation 2). ).

  On the other hand, when the operation panel 21 is not operated by the user 40, the door control unit 13 proceeds to the process of step S <b> 307, and the state where the user 40 is in the vicinity of the door in the car is constant by the human sensor 31. Determine whether the time has continued. And the door control part 13 will repeat the process of step S305, S307 until fixed time passes, and will judge whether the confinement state is continuing.

  And even if it continues for a fixed time, when the state where the user 40 exists in the vicinity of the door in the car by the human sensor 31 or when the user does not operate the operation panel 21, the door control unit 13. Determines that the confinement state continues, and proceeds to the process of step S308.

  Next, in step S308, the door control unit 13 controls the operation panel control unit so that the door 1 can be opened / closed from the operation panel 21 with a minute movement width ΔW in order to facilitate the cancellation of the door interference state. A command is issued to 22. As a result, the user 40 can eliminate the door interference state by opening and closing the door 1 within the range of the minute movement width ΔW as necessary (corresponding to the control operation 3 ′).

  If the door interference state is not resolved even after a certain period of time has elapsed after the operation permission in step S308, the door control unit 13 proceeds to step S310, stops the elevator, and reports the abnormal state to the outside. Then (corresponding to the control operation 3), a series of processing is terminated.

  On the other hand, if the door interference state is resolved before a certain time has elapsed after the operation is permitted in step S308, the door control unit 13 proceeds to the process in step S306 to restore the normal operation mode, and a series of steps. The process ends. It should be noted that steps S308 and S309 are not performed, and if YES is determined in step S307, the process immediately proceeds to step S310, and an abnormality alarm process can be performed.

  As described above, according to the first embodiment, when the passenger trapped in the car detects that the button cannot be operated even after a predetermined time, the door is moved by a minute movement amount as the first step. It is moved in the open direction to determine whether the confinement state can be resolved. Then, if the confinement state is not canceled even after the first stage processing, the door can be opened / closed only within the range of the minute movement amount as necessary to determine whether the confinement state can be resolved. Deciding.

  By having such a configuration and processing, it is possible to avoid the pinched state without suddenly moving the door to the fully open position, and quickly suppress the occurrence of a secondary disaster into the car. Rescue passengers trapped.

  The rescue operation of the present invention described above is not limited to when a fire occurs, and can be executed in response to detection of a confinement state even during normal operation.

  Further, in the above-described embodiment, the case where the human sensor is provided in the vicinity of the door has been described. However, the confinement state that is a problem in the present invention is not limited to the state sandwiched between the doors. The present invention can be applied not only in the vicinity of the door 1 but also when a situation occurs in which a passenger in the car is detected and the operation panel cannot be operated within a certain time period.
