Abstract

PROBLEM TO BE SOLVED: To relieve an installation worker from burden during running-in operation. SOLUTION: An existing inspection lamp switch in a key box and car call uppermost and lowermost floor buttons are operated using code numbers to start running-in operation. The running-in operation automatically repeats floor- stop move-up/down operation and floor-end straight operation for a certain time. To prevent the getting-in of general passengers during running-in operation, response to a hall call is prohibited, announcement for guidance is prohibited and a car is lit off. After the passage of a certain time, the car is reset to the lowermost floor to finish the running-in operation. If troubles occur during running-in operation, the operation is interrupted immediately. Automatic running-in operation for a certain time gives less burden to the installation worker and saves time and expenses. Thus, the condition of the elevator can be accurately seized by the installation worker and the initial troubles can be minimized after delivery to a customer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator apparatus provided with means for supporting an operator during the break-in operation of an elevator which is carried out before a customer is handed over.

[0002]

2. Description of the Related Art Conventionally, in most cases, inspection of an elevator before delivery of a customer can be done by whether or not various control operations are possible and a few round trips. An automatic inspection method for an elevator after the customer is handed over is disclosed in, for example, Japanese Patent Laid-Open No. 5-2.
No. 4759 gazette confirms that the car door is closed from a remote location immediately before the start of the car traveling operation, checks the car call and hall call, and registers the car call only when there is no call. Then, it is disclosed that the running condition check, the landing level check, the door open / closed condition check, and the like are performed. Further, Japanese Patent Laid-Open No. 2000-344436 discloses that a car call is remotely generated, acceleration during traveling is detected, and whether or not the comfort of the elevator is comfortable is determined. Further, Japanese Laid-Open Patent Publication No. 6-144736 proposes that when the pause switch is operated, the automatic inspection operation is started, and when there is an abnormality, a notification is sent to the control center via the communication device.

[0003]

However, actual causes of initial failure include vibration of the car, squeaking of the door, occasional cancellation of the call, and emergency stop.

At the stage of installation completion, there is a phenomenon that it does not operate continuously but starts to occur only after operating for several hours, but a long running-in operation not only imposes a heavy burden on the operator, And costly. In addition, when the microcomputer malfunctions due to noise or the like, it occurs only once every several hours, which is difficult to find.

On the other hand, in the above-mentioned prior art relating to automatic inspection of elevators, it is basically necessary to install a remote control device, and during a transitional period such as during installation, it is still in a state before the remote control device is installed. In many cases, there is a drawback that automatic inspection operation cannot be performed unless a remote control device is installed.

[0006] A first object of the present invention is to provide an elevator control method or control device that can reduce the burden on the operator when the elevator is running in before the customer is handed over.

A second object of the present invention is to make it possible for the actual installer to reliably grasp the elevator state before customer delivery, and to reduce the occurrence of initial failure after customer delivery.

A third object of the present invention is to realize a break-in operation by using an existing inspection switch or car call button without requiring a new switch or other device.

[0009]

A first feature of the present invention is that a plurality of modes of operation are repeated for a certain period of time in response to a predetermined operation of a predetermined switch in an elevator car. Is.

A second feature of the present invention is that the means for storing the procedure for operating the elevator in a plurality of predetermined modes and the predetermined switch in the elevator car are operated as scheduled. The operation control means for repeating the operation in the plurality of modes for a predetermined time is provided.

Another feature of the present invention is that existing switches, such as switches in the key box of the car operating panel and / or car call buttons are operated in accordance with the scheduled operation. This is to provide an operation control means for repeating a plurality of modes of operation including a direct operation mode and an operation mode in which all floors within the service range are stopped for a certain period of time.

Another feature of the present invention is that, in order to prevent passengers from boarding during the break-in operation, the hall call response is blocked during the operation of the plurality of modes by the operation control means, and the car interior lighting is controlled. It is to turn off the lights, block the lighting of the landing indicator, or stop the guidance broadcasting to the landing. In this case, it is desirable that the car call registration be valid in order to evacuate ordinary passengers who have accidentally boarded.

Still another feature of the present invention is that
The operation control means for repeating the operation in a plurality of modes for a certain period of time is provided with means for artificially creating a car call in the elevator control device.

In a preferred embodiment of the present invention,
Existing check switches and car calls The top and bottom floor buttons have been operated in a predetermined manner to start a break-in operation in which each floor stop operation and direct operation between floor ends are repeated for a certain period of time. In order to prevent passengers from boarding, the hall call response is blocked, guidance broadcasting is prohibited, and the lights inside the car are turned off. If the abnormality detection means of the elevator operates during this break-in operation, a break-in operation interruption means is provided to end the break-in operation immediately, and after this operation is completed, the car is generated due to factors such as car distortion and rail installation status. It is possible to confirm the state of each elevator equipment after the break-in operation by checking whether the elevator operation control microcomputer malfunctions due to vibration, abnormal operation of door open / closed state, and noise in the building.

More specifically, in the break-in operation of the elevator, after getting in the car on any floor and turning on the inspection switch in the operation panel in the car, call the car on the top floor and the bottom floor. Start by pressing the buttons at the same time. Thereby, based on the procedure preset and stored in the storage means such as the ROM or the RAM, the uppermost floor direct ascending operation, the lowermost floor orthogonally descending operation, each floor stop ascending operation, and each floor stop descending operation are repeatedly operated, and the predetermined operation is performed. Continue for hours. In addition, at this time, the hall call is invalidated and the lighting inside the car is also turned off.
It prevents passengers from getting into the car during the main operation, and even if they get into the car, they can get off at the destination floor by validating the registration of the destination floor.

Other objects and features of the present invention will be clarified in the following description of the embodiments.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an elevator apparatus according to an embodiment of the present invention. In the figure, 1 is an elevator car that serves a plurality of floors, 2 is a counterweight that is placed opposite to the elevator cars, and 3 is a hoisting electric motor that drives the elevator car 1 up and down. 4 is a communication device and an input / output device for receiving and transmitting signals with the elevator control device 5, and a door 1
Signals from the control device 5 are input to and output from the in-car operation panel 11 via the on-car device box composed of a microcomputer for controlling opening and closing of the car 2, and the on-car device box 4.

Reference numeral 5 is an elevator controller, 6 is a microcomputer controller, which is a central processing unit CPU and memory RO.
It is composed of M, RAM and the like. The program in the microcomputer is composed of a group of control function modules necessary for operating various elevators, and FIG. 1 shows only main function units. Elevator operation basic control unit 61
Includes a microcomputer operating system, various task activation management, input / output processing, timer processing, operation mode determination processing, and the like. Running-in control unit 62
Executes the running-in operation control directly related to the present invention in the control function module called from the elevator operation basic control unit 61.

The details of the break-in operation control will be described later, but in brief, it is encrypted by operating the existing check light switch and the car call on the top floor and the car call on the bottom floor in the key box of the operation panel in the car. Starts from the point of being operated. The elevator control device 5 side artificially registers a car call, operates the elevator, and at the same time, adds the traveling time to calculate the cumulative traveling time. When a certain running time is reached, the break-in operation is automatically ended.
Also, if a failure occurs in the elevator, the break-in operation is forcibly terminated.

The call registration control section 64 is provided in the car operation panel 11
Controls call registration in response to a car call that is input more. The door drive control unit 63 controls door opening / closing when landing on the door zone. The drive control unit 65 drives the electric motor,
The elevator is operated to move up and down, and it is controlled to land on a certain level. The operation state abnormality detection control unit 66 constantly monitors the operation state of the elevator and detects and controls an abnormality. The abnormal history / abnormal portion recording unit 67 is configured to record a failure history of an abnormal state of the elevator and also record the abnormal portion. The maintenance terminal device 68 is carried by a maintenance person to read the data recorded in the abnormal history / abnormal part recording unit 67, set the running-in operation permission / non-permission to be described later, and set the running-in operation time. It is for.

FIG. 2 is a flow chart of the break-in operation of the elevator according to the embodiment of the present invention. This process 200 is performed once / 40 times in the elevator control device 5.
This is a timer interrupt process that is repeatedly activated at a frequency of about ms. Since the break-in operation is intended to make the elevator run-in before the customer is handed over, it is necessary to prevent the passengers from performing an erroneous cryptographic operation after the customer is handed over. Therefore, when the customer is handed over, the maintenance terminal device 68 is used to set the break-in operation not to be permitted, and it is possible to prevent an accidental shift to the break-in operation control during the normal operation.

In step 201, the break-in operation permission of the elevator is determined based on whether or not the specifications are set in the ROM. In step 202, it is determined whether or not there is a switching operation to the break-in operation. After the installation worker gets inside the car 1 and uses the keys for installation and maintenance to open the key box of the operation panel 11 and turns on the existing check light switch in it, the top floor and the bottom floor By simultaneously turning on the car call button and continuing that state for 10 seconds or longer, the control is switched to the running-in operation mode. If this switching operation has not been performed, the determination in step 202 is No, and this processing ends. If the installation worker performs the operation switching operation to the running-in operation mode, step 2
From 02 to step 203, the response to the hall call button is prohibited, the guidance broadcast is prohibited, and the car interior light is turned off. This prevents general passengers from getting into the elevator car 1 during the break-in operation. Even if the passenger calls in the car, the car call button can be registered so that the passenger can get off at the destination floor.

In step 204, it is determined whether or not the duration of the current break-in operation has reached a preset predetermined time. If the predetermined time has not been reached, step 205
Then, it is determined whether the operating state abnormality detection unit 66 has detected an abnormality. If there is no abnormality here, step 30
The break-in operation is executed only after proceeding to the break-in operation subroutine of 0. Details of the break-in operation will be described later with reference to FIG.

When it is determined in step 204 described above that the duration of the current running-in operation has reached the preset predetermined time, the elevator car 1 is returned to the lowest floor (first floor) in step 206. Then, in step 207, the running-in operation is normally terminated. The predetermined time is data stored in the ROM in advance. This ROM data is set to 4 hours from the viewpoint that the initial abnormality can be sufficiently manifested, and can be arbitrarily changed at the site by the maintenance terminal device 68.

If an abnormality is detected in the abnormality monitoring of the elevator in step 205 described above, step 20
In step 8, the break-in operation is immediately terminated, and step 209
Then, the maintenance staff requests improvement (alarm, display) of the abnormal cause, and at step 210, this processing ends.

As described above, there is a break-in operation permission specification (201), the installation worker performs a switching operation to the break-in operation (202), and restrains general passengers from boarding (20).
3) If the running-in duration does not exceed the predetermined time (204) and no abnormality is detected (20)
5) Then, the process proceeds to the break-in operation subroutine 300 described in detail in FIG.

FIG. 3 is a flowchart of the break-in operation subroutine 300 according to the embodiment of the present invention. The running-in operation is such that the top floor direct ascending operation → the bottom floor direct descending operation → each floor stop ascending operation → each floor stop descending operation → top floor direct ascending operation → ... .

First, in steps 301 to 304, it is determined whether or not the present operation mode is one of the above operation modes. When these determination results do not belong to any of the operation modes 1 to 3, step 3
Proceeding to 05, a car call to the uppermost floor is artificially registered in the elevator control device 5 to execute the uppermost floor direct rising operation. After registering the car call to the top floor, the process returns in step 306 and step 2 in FIG.
Returning to 04, if the running-in duration time is still within the predetermined time, the routine proceeds to step 205, and if no abnormality is detected, the running-in subroutine 300 is returned again.

Referring again to FIG. 3, since the uppermost floor of the vehicle is running upright, the determination in step 301 is YE.
In step 306, the arrival at the top floor is waited for, and in step 307, a car call to the bottom floor is made, and the bottom floor direct descending operation is executed.

Similarly, steps 204 and 20 in FIG.
Returning to step 5, after confirming that the running-in duration time is still within the predetermined time and that no abnormality is detected, the routine returns to the running-in subroutine 300 again.

Referring again to FIG. 3, this time, since the bottom floor direct descending operation is underway, the determination in step 302 is YE.
In step 308, waiting for arrival at the lowest floor is performed in step 308, and in step 309, a car call to each floor is made, and each floor stop operation is executed.

Similarly, steps 204 and 20 of FIG.
Returning to step 5, after confirming that the running-in duration time is still within the predetermined time and that no abnormality is detected, the routine returns to the running-in subroutine 300 again.

Referring again to FIG. 3, since the stop and rise operation of each floor is underway, the determination in step 303 is YES.
In step 310, waiting for arrival at the top floor, in step 311, a car call to each floor is made again, and the stop descent operation for each floor is executed.

Similarly, steps 204 and 20 of FIG.
Returning to step 5, if it is confirmed that the running-in duration is within the predetermined time and no abnormality is detected, the process returns to the running-in subroutine 300 again.

Referring again to FIG. 3, since the floor stop descent operation is being performed this time, the determination in step 304 is YES.
Then, in step 312, waiting for the arrival at the bottom floor, the car call to the top floor is made again in step 305, and the direct ascent operation of the top floor is executed.

In the same manner, as long as no abnormality occurs, the break-in operation consisting of the operation modes 1 to 4 is continued for the above-mentioned predetermined time, for example, 4 hours.

In the above embodiment, the storage means (ROM or RA) for storing the operations of a plurality of predetermined modes including the preset end-to-end floor direct operation and each floor stop operation.
M), the existing switch in the key box of the elevator car inside the operation panel 11 and the car call button are operated in a predetermined order (step 202) to create a pseudo car call. (Steps 305, 307, 30
9, 311) to repeat the operations of the plurality of modes for a certain period of time (step 300 of FIG. 2: FIG. 3).
