[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator confinement remote rescue apparatus for controlling an elevator and its peripheral devices by a remote monitoring device to rescue the passenger when the passenger is confined in an elevator car.
[0002]
[Prior art]
When a passenger is confined in the elevator car, a conventional passenger rescue method will be described with reference to FIG. 20 showing a schematic configuration of the elevator. In the figure, 1 is a car carrying passengers, 2 is a call device in the car 1, 4 is a monitoring device installed in the service center, and 3 is a monitoring device 4 connected to the call device of the car 1 through a telephone line T. , 5 is an elevator operation control panel installed in the machine room, 6 is a rope for suspending the car 1, and 7 is a suspension weight suspended on the opposite side of the rope 6 from the car 1.
[0003]
When a passenger is trapped in the elevator car 1 due to some trouble, the passenger uses the communication device 2 in the car 1 to notify the communication device 3 in the monitoring device 4 in the service center. When the monitoring device 4 in the service center receives a report from a passenger in the car 1, the maintenance staff is dispatched to the local elevator. Generally, it takes some time for the maintenance staff to arrive at the local elevator. Therefore, even if the elevator stops due to a minor failure, the passenger becomes trapped in the car 1 for a long time.
[0004]
In view of this, technical development has been carried out to promptly rescue passengers in the car. For example, Japanese Patent Application Laid-Open No. 6-298462 provides an operation button for manually running an elevator at a low speed in the car, and is confined in the car. When the passenger operates the operation button according to the instruction from the monitoring center, the position in the area where the car door and the landing door engage (hereinafter referred to as the door zone), that is, the car door is opened. Although the landing door opens in conjunction with the difference between the landing and the car, the car is run at a low speed from the inside of the car to a position where it can escape to the landing, and then the car door and the landing door are opened, and the passengers are forced to enter the landing. An invention is disclosed that allows escape.
Further, in Japanese Patent Laid-Open No. 4-266378, when an abnormality of the elevator is detected, if a passenger is on the car, the reset means operates based on the reset command from the monitoring center, and the passenger rescue operation An invention is disclosed in which the inspection operation is performed after the passenger is rescued, and the normal operation is resumed if no abnormality is detected, thereby preventing the canned accident of the passenger and the serious damage of the equipment.
[0005]
[Problems to be solved by the invention]
In the former prior art, when the elevator was abnormally stopped and an abnormality report was received from a passenger trapped in the car, the service center side left the door zone as to whether the car was stopped in the door zone. I have received information to know if it has stopped between the floors, but can I drive the elevator outside of it safely, or can I perform rescue operation while ensuring the safety of passengers? Since no information for determining whether or not the rescue operation by the low-speed running of the car may be performed, it is difficult to accurately determine whether or not the service center side can perform the rescue operation.
[0006]
Also, in the latter prior art, when the elevator stops abnormally, whether the service center can safely run the elevator, or whether the rescue operation can be performed while ensuring the safety of the passengers. Since the rescue operation of the elevator is performed without making a judgment, there is a possibility of causing a serious breakdown of the equipment or a personal injury.
[0007]
The object of the present invention is to accurately determine whether or not the rescue operation of the elevator should be executed in a situation where the passenger is confined in or appears to be confined in the car. It is an object of the present invention to provide an elevator confinement remote rescue device that can safely and quickly rescue a passenger confined in a car without causing a serious breakdown or a personal injury.
[0008]
[Means for Solving the Problems]
The above-mentioned purpose is a terminal device attached to an elevator, collecting the operation data of the elevator, and monitoring the operation state thereof, and the speed of a car that can be moved up and down in the hoistway. But Passengers including a safety device for emergency stop of the elevator when an abnormality detection means such as an overspeed detection device that detects abnormally fast detects a serious abnormality of the elevator, and a low speed driving means for causing the car to run at a low speed Rescue means and communication means for transmitting the operation information of the elevator taken in from the terminal device to the monitoring device of the service center via a telephone line, and rescue the passengers trapped in the emergency stopped car In the elevator confinement remote rescue device that is performed based on a command from the monitoring device side, the remote control device that causes the monitoring device to operate the passenger rescue device remotely via a telephone line, and communication from the terminal device State display means for displaying the state of the elevator based on the operation information of the elevator taken in via the line; And accident judging means confined determining the cause of the elevator trapped accident based on the elevator operation information retrieved via the communication line from the end device, When the cause of the confinement accident in the elevator determined by the means for determining the confinement accident is that the overcurrent and overvoltage of the control power supply of the operation control panel are detected by the power supply state detection device, the vertical position of the car is the car door. And a rescue operation availability determination means for determining whether or not the rescue operation is performed if the landing door is not in an engageable door zone. Is achieved.
[0009]
Preferably, based on the cause of the occurrence of the confinement accident of the elevator determined by the confinement accident cause determination means, the rescue operation availability determination means and the confinement for determining whether the passenger rescue operation is performed to rescue the passenger confined in the car The monitoring device has an accident cause display means for displaying the cause of the occurrence of an elevator confinement accident determined by the accident cause determination means, and a monitor who monitors the monitoring device is based on the accident cause displayed by the accident cause display means. By operating the remote control means, the passenger rescue means is operated remotely.
[0010]
Furthermore, when the cause of the elevator confinement accident determined by the confinement accident cause determination means is due to the operation of the safety device, the passenger rescue means has an abnormality detection invalidation means for invalidating the abnormality detection operation of the abnormality detection means. However, when the vertical position of the car is not in the door zone where the car door and the landing door can be engaged, the monitoring person who monitors the monitoring device operates the remote control means, and the abnormality detection of the passenger rescue means is remotely disabled. The elevator and the low-speed driving means may be operated so that the elevator can run at low speed.
[0011]

Detecting the occurrence of a confinement failure based on elevator information such as the operating status of the safety device, the stop position of the car 1, the open / closed state of the landing door 9 and the car door 26, and the operating state of the call registration button in the car 1 Thus, it is a terminal device that issues a confinement failure to the monitoring device 4 in the service center via the telephone line T.
[0013]
In the reference numerals indicating the internal configuration of the rescue control device 11, reference numeral 14 denotes a power interrupting unit that resets the microcomputer that controls the operation of the elevator by turning off and on the elevator control power. Reference numeral 15 denotes an overspeed detection device 21 and a landing door. Safety device circuit short-circuit unit that short-circuits safety device circuits such as the closing switch 25 and the car door closing switch 27, 16 is a low-speed operation command unit that commands low-speed operation that causes the elevator to run at low speed, and 17 opens the electromagnetic brake 20. Electromagnetic brake opening part.
[0014]
On the other hand, as an internal configuration of the monitoring device 4 in the service center, 18 is a monitoring unit constituting the main part of the monitoring device 4, and 37 is an elevator operation control panel when a trapping failure is reported from the terminal device 12. 5 is an elevator status display unit that reads out and displays via the telephone line T from the terminal device 12 that stores the operation status information of the elevator output from 5, and 13 indicates the cause of the elevator confinement failure detected by the terminal device 12.

[0016]
As is apparent from this circuit configuration, when any one of the normally closed contacts 45 to 49 is opened, the elevator travel relay 51 is de-energized, and the elevator control circuit is the elevator travel circuit. When the relay 51 is de-energized, the elevator is stopped. The rescue control normally-open contact 50 is connected to the monitoring device 4 in the service center via the terminal device 12. When performing rescue control from a remote location, the rescue control normally-open contact 50 is safely closed. The normally closed contacts 45 to 49 of the device are artificially short-circuited so that the elevator travel relay 51 can be forcibly energized even when the safety device described above operates.
[0017]
Next, the operation of this embodiment will be described. 2-14 is a flowchart which shows the content of the confinement cause determination and passenger rescue processing performed by the monitoring part 18 of the monitoring apparatus 4. FIG.
Details of the confinement cause determination / passenger rescue process will be described below with reference to these drawings. First, in step 10 of FIG. 2, the elevator travels normally under the control of the operation control panel 5. The terminal device 12 is used for the elevator such as the operating state of the safety device such as the overspeed detecting device 21, the stop position of the car 1, the opening / closing state of the landing door 9 and the car door 26, Whether or not the elevator is operating normally is monitored based on the operation information.
[0018]
In step 20, when a confinement failure occurs during operation of the elevator, the terminal device 12 determines that a passenger is confined in the car 1 based on the operation information, and in the service center via the telephone line T. Report the occurrence of confinement to the monitoring device 4. In some cases, the trapping notification is made when the passenger in the car 1 directly contacts the communication device 3 of the monitoring device 4 in the service center using the communication device 2 in the car 1. The trapping cause determination unit 13 of the monitoring device 4 in the service center that has received the notification displays the elevator operation state information on the elevator state display unit 37, and analyzes the cause of the elevator confinement failure.
[0019]
FIG. 18 is an explanatory diagram showing a display screen of the monitoring unit 18. In the figure, the following symbols indicate display fields displayed on the display screen DS of the monitoring unit 18, and reference numeral 40 indicates the position of the car 1 and the call registration from the elevator operating state information read from the elevator operation control panel 5. A registration status display unit for displaying the status, 41 is a switch operation display unit indicating the operation status of each switch for operation confirmation and safety, 42 is a failure content display unit indicating the content of the failure, and 43 is a confinement cause determination unit 13 It is a failure cause display unit that displays the determined cause of the confinement failure, and these constitute an elevator state display unit 37. Reference numeral 44 denotes a display operation switch for the supervisor to give a command to the rescue control device 11 according to the cause of the failure displayed on the failure cause display unit 43, and configures the remote operation unit 19. In this display screen DS, the car 1 stops outside the door zone near the 6th floor, and it is determined that the cause of the confinement failure is that the safety device has operated, and the safety device short circuit push switch is selected as the operation switch 44. An example is shown.
[0020]
The service center monitor recognizes the cause of the failure displayed on the failure cause display unit 43 and uses the communication device 3 of the monitoring device 4 to talk to the passenger using the communication device 2 in the car 1. When it is determined that the passenger can be rescued by a command or instruction from the monitoring device 4 by recognizing the situation in which the passenger is confined from the passenger's story or the situation in the car 1, by operating the remote control unit 19 A command for remotely controlling the elevator to the rescue control device 11 is transmitted via the telephone line T, or the communication devices 2 and 3 are used to instruct the passengers in the car 1 to take measures and rescue the passengers. To do.
[0021]
In the following steps, details of the confinement cause determination / passenger rescue process will be described focusing on the content of the determination process of the confinement cause determination unit 13. In step 30, it is determined whether power is supplied to the elevator. If no power is supplied to the elevator, the process proceeds to step 900, and the process is terminated because it cannot be rescued. If the power is supplied to the elevator, the process proceeds to step 100, and it is determined whether or not the operation panel described later in the car 1 is erroneously operated. If the operation panel is erroneously operated, the process proceeds to step 101 in FIG. 3, and the communication panel 3 of the monitoring device 4 in the service center is used to switch the operation panel to the normal state for the passenger through the communication device 2 in the car 1. Instruct them to return to. Subsequently, at step 102, it is determined whether the elevator has traveled to the nearest floor and the car door 26 has been opened. If the door is opened, it is determined that a confinement failure has occurred due to an erroneous operation of the operation panel in the car 1, the rescue is completed (step 103), and the elevator is returned to normal operation (step 104). If the car door 26 is not opened in step 102, the rescue is impossible (step 105) and the process is terminated.
[0022]
If it is determined in step 100 of FIG. 2 that there is no erroneous operation of the operation panel, the process proceeds to step 200, where the current flowing through the operation control circuit for controlling the winding unit 36 and the applied voltage are more than specified due to a failure of a component in the power circuit. Determine whether it is a value. If overcurrent and overvoltage are detected in step 200, the power supply system on the building side may be adversely affected if the elevator power supply is interrupted or the elevator is driven by the operation control circuit.
[0023]
Therefore, if the current flowing through the operation control circuit and the applied voltage are above the specified values, the process proceeds to step 201 in FIG. 4, and the call device 3 of the monitoring device 4 in the service center is used. The passenger is instructed to press a door opening button (to be described later) for opening the car door 26 in the car 1 through the communication device 2, and it is determined in step 202 whether the car door 26 is opened. If it is opened, the process is terminated as a rescue completion (step 203).
[0024]
If the car door 26 is not opened in step 202, it is determined in step 204 whether the car 1 is in a position where the landing door 9 and the car door 26 can be engaged, that is, whether the elevator is in the door zone. Determine. If it is determined that the determination result is in the door zone, the process proceeds to step 40 in FIG. 5 to determine whether the car 1 is in the door zone so that passengers in the car 1 can manually open the car door 26. Process to get reconfirmed. Subsequently, at step 41, an operation command is transmitted from the remote control unit 19 of the monitoring device 4 in the service center to the power supply interrupting unit 14 of the rescue control device 11, the drive system control power supply of the elevator is shut off, and the car door The driving force closing and energizing 26 is released.
[0025]
Next, in step 42, the call device 3 of the monitoring device 4 in the service center instructs the passenger to open the car door 26 by hand through the call device 2 in the car 1. In step 43, the detection signal from the car door closing switch 27 is checked to determine whether or not the car door 26 is opened. If it is opened, the rescue is completed (step 44). The process ends as step 45).
[0026]
If it is determined in step 204 that the vehicle is outside the door zone, the process proceeds to step 50 in FIG. 6 to open the electromagnetic brake 20 and drive the elevator to the nearest floor to rescue passengers in the car 1. Based on the elevator operation state information displayed on the elevator state display unit 37, the door zone detection signal and the elevator speed detection signal can be normally detected, and the electromagnetic brake 20 is opened to run the elevator. Make sure it is in good condition.
[0027]
Next, proceeding to step 51, an operation command is transmitted to the low speed operation command unit 16 of the rescue control device 11 by operating the remote control unit 19 of the monitoring device 4 in the service center, and the elevator is switched to the low speed operation mode. Let Here, the elevator operation is switched to the low-speed operation mode when the emergency operation is restored while the electromagnetic brake is released in the normal operation mode. This is because there is a possibility of switching to driving by a circuit and inducing a failure again.
[0028]
Subsequently, in step 52, an operation preparation command is transmitted to the electromagnetic brake release unit 17 of the rescue control device 11 by the operation of the remote control unit 19 of the monitoring device 4 in the service center. In step 53, the call device 3 of the monitoring device 4 in the service center is used to instruct the passenger to press the car call button to the nearest floor in the car 1 through the call device 2 in the car 1. To do. As a result, it is determined whether or not the electromagnetic brake 20 is released and the elevator has traveled. If the elevator has moved, the process proceeds to step 54 to determine whether or not the car 1 has arrived at the nearest floor. If the determination result is negative, the electromagnetic brake 20 is kept released until the car 1 arrives at the nearest floor.
[0029]
If the car 1 has arrived at the nearest floor, in step 55, an operation release command is transmitted to the electromagnetic brake release unit 17 of the rescue control device 11 by operating the remote control unit 19 of the monitoring device 4 in the service center. To do. Subsequently, in step 56, an operation command is transmitted from the remote operation unit 19 of the monitoring device 4 to the power supply interrupting unit 14 of the rescue control device 11 to remotely shut off the power supply of the elevator. Next, in step 57, an operation release command is transmitted to the low speed operation command unit 16 of the rescue control device 11 by operating the remote operation unit 19, and the elevator is switched to the normal operation mode.
[0030]
Subsequently, in step 58, the communication device 3 of the monitoring device 4 is used to talk to the passenger through the communication device 2 in the car 1 and to instruct the passenger to open the car door 26 by hand. In step 59, it is determined whether or not the car door 26 is opened. If the car door 26 is opened, the rescue is completed (step 60) and the process is terminated. In step 53, if the weight in the car 1 is substantially equal to the weight of the suspension weight 7 and the elevator does not move, the rescue is impossible (step 61), and the process is terminated without rescuing the passenger. .
[0031]
If overcurrent and overvoltage are not detected in step 200, the process proceeds to step 300, and it is determined whether or not the position detection device (not shown) of the car 1 has failed. If the position detection device is out of order, the process proceeds to step 301 in FIG. 7 to check whether the elevator is stopped at the position where the upper limit switch 22 or the lower limit switch 23 in the hoistway 10 is operated. judge. This is because even when the position of the car 1 cannot be detected, when the car 1 descends to the lowest position of the hoistway 10 or rises to the uppermost position, it can land on the lowermost floor or the landing 8 on the uppermost floor. .
[0032]
If it is determined in step 301 that the car 1 is on the uppermost floor or the lowermost floor, the process proceeds to step 302 where the power interrupting unit of the rescue control device 11 is operated by the operation of the remote control unit 19 of the monitoring device 4. The operation command is transmitted to 14, and the power supply of the elevator is remotely interrupted. Thereafter, the process proceeds to step 40 in FIG. 5, and the processes in and after the above-described step 41 for causing the passengers in the car 1 to manually open the car door 26 are executed. In step 301, if the car 1 is not on the terminal floor, the rescue is impossible (step 303), and the process is terminated.
[0033]
In step 300 of FIG. 2, if the position detection device of the car 1 has not failed, the process proceeds to step 400 to check whether the elevator operation control microcomputer has become abnormal and the elevator is inoperable. judge. If the microcomputer is abnormal, the process proceeds to step 401 in FIG. 8, and an operation command is sent to the control power interrupter 14 of the rescue controller 11 by operating the remote controller 19 of the monitoring device 4 in the service center. To interrupt the elevator control power. This is because the microcomputer may return to normal by performing such intermittent processing. In step 402, it is determined whether the microcomputer has been restored. If the microcomputer is not restored, the process is terminated as it cannot be rescued (step 406).
[0034]
On the other hand, if the microcomputer is restored, the process proceeds to step 403 to determine whether or not the car door 26 is opened. If the car door 26 is opened by looking at the detection signal of the car door close switch 27, the process proceeds to step 404, and the remote control device 4 is used to prevent other passengers from using the elevator after the rescue is completed. By operating the operation unit 19, an operation command is transmitted to the control power supply interrupting unit 14 of the rescue control device 11, and the control power supply of the elevator is shut off, thereby completing the rescue operation (step 405).
[0035]
On the other hand, if the car door 26 is not opened in step 403, the process proceeds to step 407 to determine whether the elevator is in the door zone. If it is in the door zone, the process proceeds to step 40 in FIG. 5, and the processing of step 41 and the subsequent steps for causing the passenger in the car 1 to manually open the car door 26 is executed. If it is determined in step 407 that the elevator is outside the door zone, the process proceeds to step 408 to determine whether the elevator travels to the nearest floor. When traveling to the nearest floor, the routine proceeds to step 409, where it is determined whether or not the car door 26 is opened after the elevator arrives at the nearest floor. If the car door 26 is opened, the process is terminated as a rescue completion (step 405) through the above-described step 404, and if the car door 26 is not opened, the process from the above-described step 40 in FIG. 5 is performed.
[0036]
Next, if the elevator does not travel to the nearest floor in step 408 and if the microcomputer for controlling the operation of the elevator is not abnormal in step 400 of FIG. 2, the process proceeds to step 500 where the landing door 9 is closed. It is determined whether or not the landing door closing switch 25 that detects that the vehicle is closed. If it is open, control proceeds to step 501 in FIG. 9 to determine whether the elevator is in the door zone. If it is outside the door zone, there is a risk of personal injury of the person on the landing 8 side, so that the rescue is impossible (step 506) and the process is terminated. In step 501, when it is in the door zone, the process proceeds to step 502, where an operation command is transmitted from the remote control unit 19 of the monitoring device 4 to the power interrupting unit 14 of the rescue control device 11 to remotely interrupt the power supply of the elevator. Subsequently, at step 503, it is determined whether or not the car door 26 is opened.
[0037]
When the car door 26 is opened, the process proceeds to step 504, and after the rescue is completed, in order to prevent other passengers from using the elevator, the remote control unit 19 of the monitoring device 4 is connected to the power interrupter 14 of the rescue control device 11. The operation command is transmitted to the elevator, the power supply of the elevator is remotely shut off, and the process is terminated as the rescue is completed (step 505). If the car door 26 is not opened, the process proceeds to step 40 in FIG. The processing in step 41 and subsequent steps is executed to allow passengers in 1 to open the car door 26 manually.
[0038]
When the landing door closing switch 25 for detecting that the landing door 9 is closed in step 500 in FIG. 2, the routine proceeds to step 600, where it is determined whether or not the elevator safety device is operating. . Examples of the operation of the safety device include a case where a foreign object is caught in the overspeed detection device 21 or an abnormality that occurs due to a cause such as a passenger mischievously swinging the car 1 up and down is detected. When the safety device is operating, the process proceeds to step 601 in FIG. 10 to determine whether or not the elevator can run by short-circuiting the safety device circuit. In this process, for example, the speed of the car 1 immediately before the occurrence of confinement is detected, and it is determined whether or not the overspeed detection device 21 that detects the overspeed is operating normally.
[0039]
If the safety device circuit can be short-circuited in step 601, the process proceeds to step 602. If the short-circuit is not possible, the process proceeds to step 624 to determine whether the elevator is in the door zone. When in the door zone, the process proceeds to step 40 in FIG. 5, and the processing of step 41 and the subsequent steps for allowing the passengers in the car 1 to manually open the car door 26 is executed. If the rescue is impossible (step 625), the process is terminated.
[0040]
In step 602, an operation command is transmitted from the remote operation unit 19 of the monitoring device 4 to the low-speed operation command unit 16 of the rescue control device 11, and the elevator is remotely switched to the low-speed operation mode. An operation command is transmitted from the remote control unit 19 of the device 4 to the safety device circuit short-circuit unit 15 of the rescue control device 11, and the safety device circuit is short-circuited remotely to make the elevator operable.
[0041]
Next, in step 604, an operation command is transmitted from the remote control unit 19 of the monitoring device 4 to the power supply interrupting unit 14 of the rescue control device 11 to remotely interrupt the power supply of the elevator. Determine if it is in the door zone. If it is in the door zone, the process proceeds to step 606, where an operation release command is transmitted from the remote control unit 19 of the monitoring device 4 to the low speed operation command unit 16 of the rescue control device 11, and the elevator is set to the normal operation mode remotely. Next, in step 607, it is determined whether or not the car door 26 is opened.
[0042]
If the car door 26 is opened, the process proceeds to step 608, and after the rescue is completed, in order to prevent other passengers from using the elevator, the remote control unit 19 of the monitoring device 4 is connected to the power interrupting unit 14 of the rescue control device 11. The operation command is transmitted to the elevator, the elevator control power is remotely shut off, and the process is terminated as the rescue is completed (step 609). On the other hand, if the car door 26 is not opened, the process proceeds to step 40 in FIG. 5, and the processes in and after the above-described step 41 for allowing the passengers in the car 1 to open the car door 26 manually are executed.
[0043]
If the elevator is outside the door zone in step 605, the process proceeds to step 610, and it is determined whether or not the upper limit switch 22 in the upper part of the hoistway 10 is closed. When the ascent restriction switch 22 is not closed, in step 611, a low speed ascending operation command is transmitted from the remote control unit 19 of the monitoring device 4 to the low speed operation command unit 16 of the rescue control device 11 to raise the elevator at a low speed. Prepare for operation. In step 612, the communication device 3 of the monitoring device 4 is used to speak to the passenger, and the passenger is instructed to press the car call button in the car 1, thereby determining whether or not the elevator has traveled. . If the vehicle has traveled, it proceeds to step 613 to determine whether or not it has arrived at the nearest floor. If the determination result is negative, the elevator ascending operation is continued until the car 1 arrives at the nearest floor.
[0044]
If the elevator does not run in step 612 even if the car call button is pressed, an operation cancel command is issued to the low-speed operation command unit 16 of the rescue control device 11 by operating the remote operation unit 19 of the monitoring device 4 in step 619. Then, in step 620, the communication device 3 of the monitoring device 4 is used to talk to the passenger, and the passenger is instructed to release the car call button in the car 1.
