[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an operation control device and an operation control method for an elevator installed in a building having a seismic isolation structure in an intermediate part.
[0002]
[Prior art]
FIG. 6 shows an elevator apparatus for a building having an intermediate seismic isolation structure disclosed in JP-A-2001-122554.
As shown in FIG. 6, the building of the intermediate seismic isolation structure has a building divided into a high-rise section 50 and a low-rise section 51. The seismic isolation device 52 is interposed between the high-rise part 50 and the low-rise part 51, so that even if the low-rise part 51 vibrates greatly during the occurrence of an earthquake, the high-rise part 50 installed via the seismic isolation apparatus 52 has almost no vibration. Vibration is not transmitted. Such an elevator apparatus for a building having an intermediate seismic isolation structure has a guide rail 54 continuously attached to a high-rise section 50 and a low-rise section 51 via a support section 53, and guides such as guide shoes to the guide rail 54. An elevator car 56 supported by a mechanism 55 and moving up and down along the guide rail 54 is provided.
[0003]
When the elevator car 56 moves up and down across the seismic isolation device 52, the hoistway is shifted by the relative displacement between the high-rise section 50 and the low-rise section 51 as shown in FIG. , A pair of joint rails 54b attached near the seismic isolation device 52, and an intermediate rail 54c provided between the pair of joint rails 54b.
[0004]
The joint rail 54b is made to be more deformable than the other normal rails 54a and the intermediate rails 54c by partially processing the cross-sectional shape, and the joint rails 54b and the normal guide rails 54a installed on the high-rise section 50 and the low-rise section 51 are formed. The joint rail 54b and the intermediate rail 54c installed near the seismic isolation device 52 are continuously connected to form the guide rail 54, and are arranged so as to straddle the seismic isolation device to secure a hoistway that can be operated continuously. . Hereinafter, a portion sandwiched between the pair of joint rails 54b is referred to as a seismic isolation structure of the elevator apparatus.
[0005]
[Problems to be solved by the invention]
In an elevator apparatus for a building having an intermediate seismic isolation structure, when an earthquake occurs, the upper part 50 and the lower part 51 are displaced as shown in FIG. 7, and the seismic isolation apparatus 52 is distorted following this deviation. Accordingly, the guide rail 54 secures the function as a guide rail without deforming the normal rail 54a and the intermediate rail 54c as much as possible by only the deformation of the joint rail 54c.
[0006]
In addition, as shown in the elevator association technical data, the control operation of the elevator device at the time of occurrence of an earthquake is stopped by moving to the nearest stopable floor when an earthquake is detected. Alternatively, when it takes a predetermined time or more to reach the nearest floor, the vehicle is suddenly stopped. After a sudden stop, the vehicle is driven at a low speed by an operation switch such as a monitoring panel.
[0007]
However, in the elevator apparatus for a building having the above-mentioned intermediate seismic isolation structure, if the distortion of the hoistway guide rail is large at the time of the earthquake, there is a problem that the elevator car passes through the seismic isolation structure position. There is a danger that it will not be able to run, and it was shown in the "Elevator Technical Standards Explanation (2002 Version)" published by the Elevator Association (2002 edition of Housing Guidance Division, Housing Bureau, Ministry of Land, Infrastructure, Transport and Tourism). There was a problem that control only during an earthquake was not enough.
[0008]
The present invention is intended to solve the above-mentioned problems, and controls passengers safely in the event of an earthquake by controlling the operation of the elevator device from the position and traveling direction of the elevator car with respect to the seismic isolation device position in the control operation at the time of earthquake. An elevator operation control device and control method that can be rescued are obtained.

[0019]
FIG. 2 is a diagram showing an overview of the elevator apparatus, in which floor detection switches 5 are respectively installed on floors 10 of a landing. The car 11 travels while calculating the floor at which the car can be stopped from the traveling speed and the deceleration time. An example in which the seismic isolation structure 13 is installed on the third floor is shown.
[0020]
Next, a specific operation will be described with reference to the flowchart of FIG.
The flowchart in FIG. 3 is an operation flow in the control operation at the time of the occurrence of an earthquake.
[0021]
When an earthquake occurs, in steps S301 and S303, it is determined whether or not the acceleration of the generated earthquake is large with respect to the recommended low and low settings of the earthquake sensor recommended by the height of the building. In step S301, if the extra low detector operates, the process proceeds to step S303. If the extremely low detector does not operate, the process proceeds to step S302 and normal operation is continued. If the low sensor operates in step S303, the process proceeds to step S304, and it is determined whether the elevator car is running. If the car is running, the process proceeds to step S305, and it is determined whether the car passes through the seismic isolation structure before reaching the nearest floor and stopping. This is determined based on the current position and the traveling direction of the car that is traveling and the position of the seismic isolation structure. If it is determined that the car is passing, the process proceeds to step S307 to stop the elevator emergency.
[0022]
If it is determined that the car does not pass through the seismic isolation structure, the process proceeds to step S306, and it is determined whether the car travels for 10 seconds or more before stopping at the nearest floor. If it takes 10 seconds or more, the process proceeds to step S307, and the elevator is emergency stopped. If it is less than 10 seconds, the process proceeds to step S308 and stops at the nearest floor.
[0023]
After stopping at the nearest floor, the door of the car is opened in step S309, and the passenger is dropped off. If the car is not running in step S304, the process also proceeds to step S309. Thereafter, at step S310, the door of the car is closed after a lapse of a predetermined time. In step S311, if the passenger who has not yet got down presses the door open button, the process returns to step S309. However, unless the door open button is pressed from inside the car, in step S312 there is no passenger in the car and the operation is stopped. .
[0024]
If the low-sensitivity sensor is not operating in step S303, the process proceeds to step S313 to determine whether the elevator car is running. If the car is traveling, the car is stopped at the nearest floor in step S314, and the car door is opened in step S315 to drop the passenger. If the car is not running in step S313, the process proceeds to step S315. Thereafter, in step S316, the car door is closed after a predetermined time has elapsed. In step S317, if the passenger who has not yet got down presses the door open button, the process returns to step S315. However, as long as the door open button is not pressed from inside the car, the operation stops with no passengers.
[0025]
If the sensor with the extremely low sensitivity is automatically or manually reset in step S318, the process proceeds to step S319 to return to normal operation.
[0026]
As described above, in the first embodiment, it is determined whether the traveling car arrives at the nearest floor and passes through the seismic isolation structure before stopping when the low detector operates. Judging from the current position of the car, the running direction and the position of the seismic isolation structure, if it is determined that the car will pass, the elevator will be emergency-stopped. In consideration of the possibility that the guide rails, particularly the indirect rails, may be deformed, it is possible to prevent the occurrence of accidents such as the guide shoes coming off due to the passage of the car, which in turn leads to passenger safety. Can be secured.
[0027]
Embodiment 2 of the invention
FIG. 4 shows a flowchart of the operation of the operation control device for the elevator apparatus according to Embodiment 2 of the present invention. The configuration of the operation control device itself is the same as that of the first embodiment.
FIG. 4 shows a procedure after the emergency stop of the elevator in step S307 in the flowchart of FIG. 3 shown in the first embodiment.
[0028]
After the elevator emergency stop in step S401, the process proceeds to step S402 to check various safety circuits. Here, the various safety circuits include a door open detection circuit, a car position detection circuit, a brake detection circuit, and the like. If any one of the various safety circuits has an abnormality, the process proceeds to step S403, and the abnormality of the safety circuit is displayed or notified in the car, and an alarm to that effect is issued to the management room. Thereafter, the operation is stopped in the state of stopping in step S404.
[0029]
If there is no abnormality in the various safety circuits, the process proceeds to step S405, and it is determined whether or not the high sensor has been activated due to the earthquake. Here, if the high sensor has been activated, that is, if the earthquake is equal to or greater than the set high acceleration, the process proceeds to step S406, and the current position of the car at the emergency stop enters the seismic isolation structure. It is determined whether or not. If the car is in the seismic isolation structure, the flow returns to step S403 to display or inform the car that the car is in the seismic isolation structure, and issue an alarm to that effect to the management room. Thereafter, the operation is stopped in the state of stopping in step S404.
[0030]
If it is determined in step S406 that the car has stopped at a place other than the seismic isolation structure, the flow advances to step S407 to alert the control room that the car has stopped after the high sensor has been activated. I do.
[0031]
In response to this, the control room resets the high-sensitivity sensor in step S408, and turns on the low-speed operation switch during an earthquake. Proceeding to step S409, the rescue operation mode is entered.
[0032]
If the high sensor is not operating in step S405, the process proceeds to step S410, and after about one minute from the emergency stop, the car and the weight are caused to run at a low speed in a direction away from each other, and in step S411, stop at the nearest floor. .
[0033]
As described above, in the second embodiment, in the case of a large earthquake in which the elevator is stopped and the sensor at a higher height is operated after the emergency stop of the elevator, if the position of the car that has been stopped in the seismic isolation structure is: A warning to that effect was issued to the control room, and the car was displayed or informed in the car and the operation was suspended while the car was stopped, so the car that had entered the seismic isolation structure moved the guide rail. It is possible to prevent the occurrence of secondary accidents such as departure.
[0034]
In addition, in the event of a large earthquake in which the elevator is stopped and a higher sensor is activated, if the position of the car that has been stopped is not located in the seismic isolation structure, a notice to that effect is issued to the control room. Switching to the rescue operation by switching the switch on the control room side allows the passengers to be rescued more safely.
[0035]
Embodiment 3 of the Invention
FIG. 5 shows a flowchart of the operation of the operation control device for the elevator apparatus according to Embodiment 3 of the present invention. The configuration of the operation control device itself is the same as that of the first embodiment.
FIG. 5 shows a procedure after shifting to the rescue operation mode in step S409 in the flowchart of FIG. 4 shown in the second embodiment.
[0036]
After shifting to the rescue operation mode in step S501, the process proceeds to step S502 to determine whether the current position of the stopped car is above the intermediate position of the hoistway. If it is above the intermediate position, the process proceeds to step S503 to determine whether to pass through the seismic isolation structure before stopping at the nearest floor in the ascending direction. If the vehicle passes through the seismic isolation structure, the process proceeds to step S504, and it is determined whether the vehicle passes through the middle position of the hoistway before stopping at the nearest floor in the descending direction. If it is determined that the vehicle passes through the intermediate position of the hoistway, the process proceeds to step S505, and the operation is stopped while the vehicle is stopped.
[0037]
If the current position of the car is below the intermediate position of the hoistway in step S502, the process proceeds to step S506 to determine whether to pass through the seismic isolation structure before stopping at the nearest floor in the descending direction. If the vehicle passes through the seismic isolation structure, the process proceeds to step S507, and it is determined whether the vehicle passes through the middle position of the hoistway before stopping at the nearest floor in the ascending direction. If it is determined that the vehicle passes through the intermediate position of the hoistway, the process proceeds to step S508, and the operation is stopped with the vehicle stopped.
[0038]
It is determined that the vehicle does not pass through the seismic isolation structure before stopping at the nearest floor in the ascending direction in step S503, and does not pass through the middle position of the hoistway before stopping at the nearest floor in the ascending direction in step S507. If it has, the process proceeds to step S509 to set the traveling direction to the ascending direction.
[0039]
It is determined that the vehicle does not pass through the seismic isolation structure before stopping at the nearest floor in the descending direction in step S506, and that the vehicle does not pass through the middle position of the hoistway before stopping at the nearest floor in the descending direction at step S504. If it has, the process proceeds to step S510, and the traveling direction is set to the descending direction.
[0040]
After the traveling direction is set in steps S509 and S510, traveling is started in step S511, the vehicle is stopped on the nearest floor in step S512, and the rescue operation ends.
[0041]
As described above, in the third embodiment, during the rescue operation, the traveling direction is temporarily determined based on the position of the car with respect to the intermediate position of the hoistway, and the vehicle passes through the seismic isolation structure before reaching the nearest floor in that direction. Judgment is made, and when passing, it is made to run in the opposite direction, so that it can be prevented from passing through the seismic isolation structure that may have been deformed by the influence of the earthquake.
[0042]
Also, it is determined whether the vehicle passes through the middle position of the hoistway before reaching the nearest floor in the opposite direction. If this also passes, the car will be stopped with the car stopped, so it will pass through the middle position of the hoistway where either the car or the weight may fall off the rail and the car and the weight may collide due to the earthquake. Can be eliminated.
Thereby, occurrence of an accident during rescue operation can be prevented.
[0043]
【The invention's effect】
According to the present invention, it is determined whether the running car arrives at the nearest floor when the earthquake occurs and passes through the seismic isolation structure before stopping, by determining the current position of the running car, the traveling direction and the seismic isolation structure. By judging from the position, an elevator operation control device and an operation control method with higher safety can be obtained.
