Abstract

PURPOSE:To perform the inspecting operation of a car without operating an automatic inspecting device in a machine room by forcedly giving an inspecting operation starting instruction to a control device when an operation button is operated as prescribed while a maintenance switch installed on an operation panel in the car is kept on. CONSTITUTION:When a maintenance man rides into the car 6 of an elevator, and operates a maintenance switch 7f of an operation panel 7, he waits until the prescribed operation instruction set in a memory 1c in advance is generated from the operation panel 7. When the prescribed operation instruction is confirmed and the elevator operation state is confirmed as the normal waiting state, he waits until the number of registers by car call buttons 7c-7e and the number of registers by a hall call button 9 become 0, then he gives an inspecting operation starting instruction to a control device 3 to start the inspecting operation of the car 6. When the landing call button 9 is pushed during the inspecting operation and a call is registered on the elevator, the maintenance man interrupts the inspecting operation, and the car 6 responds to the floor where the call is generated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator capable of automatically inspecting each part and storing the inspection result in response to a command from a monitoring center, and in particular, it is necessary to promptly respond to a call of a car under inspection. It relates to an automatic inspection mechanism for an elevator.

[0002]

2. Description of the Related Art Conventionally, when inspecting an elevator, a maintenance worker goes to the site to board a car and inspects the operation of each part while operating the car at low speed or at the same high speed as during normal operation. Was common,
In recent years, Japanese Examined Patent Publication No. 2-8870 and Japanese Examined Patent Publication No. 2-3651
As disclosed in Japanese Patent Laid-Open No. 2 publication, elevators that have an automatic inspection device connected to a monitoring center via a communication line and can automatically inspect each part and store inspection results in response to commands from the monitoring center are widespread. I am doing it.

That is, such an automatic inspection device issues an inspection operation start command at a preset scheduled date and time, and the control device receiving this command causes the car to perform low-speed or high-speed inspection operation, and this inspection is performed. During operation, detection signals from sensors and switches provided at various places are incorporated into the automatic inspection device. Then, based on these detection signals, the automatic inspection device calculates the operating state data and determination data of the elevator and stores it in the memory, and the operating state data and determination data thus stored can be transmitted to the monitoring center at any time, The operation of each part of the elevator can be inspected at any time even if maintenance personnel do not go to the site.
As a result, if it is deemed necessary by the monitoring decision at the monitoring center, maintenance personnel can be dispatched to the site to perform adjustment and maintenance at times other than during regular inspections, and maintenance and inspection to maintain the elevator in a safe operating state. The work can be performed efficiently, and the change tendency of the operating state of the elevator over a long period of time can be grasped by the operating state data and the judgment data stored in the memory, and the highly effective maintenance and inspection work can be performed with reference to this.

[0004]

By the way, since the passenger cannot use the car while inspecting and driving the car, it is preferable to check the elevator at midnight when the frequency of use is low. However, in emergency elevators installed in hospitals and elevators in multi-tenant buildings that operate almost 24 hours a day, it is necessary to keep them available even at midnight. I can't do it. Therefore, for elevators in which passengers are expected to appear even during inspection operation like this, maintenance personnel will board the car and inspect the operation of each part without using the automatic inspection device as before. Otherwise, the maintenance personnel operate the automatic inspection device to forcibly generate the inspection operation start command to perform the inspection operation of the car, and in either case, dispatch the maintenance personnel to the site. By doing so, it is considered that the inspection operation can be interrupted as soon as the hall call is registered.

However, when the maintenance staff inspects the operation of each part without using the automatic inspection device as in the former case, the operation state data and the judgment data are not stored in the memory, so that the operation state of the elevator for a long period of time is not stored. However, there is an inconvenience that it is not possible to grasp the change tendency of No. 1 and therefore it is not possible to perform maintenance and inspection work with reference to this.

On the other hand, if the maintenance person operates the automatic inspection device to perform the inspection operation of the car as in the latter case, it is convenient because the operation state data and the judgment data are stored in the memory. In order to operate the automatic inspection device installed in the machine room, it is very troublesome because the maintenance staff must go to the machine room, and the inspection operation is performed even when the maintenance staff goes to the site. There was a problem that could not be confirmed.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to allow a maintenance person to easily perform an inspection operation of a car, and to operate while confirming the inspection operation. An object of the present invention is to provide an automatic inspection mechanism for an elevator that can store state data and determination data in an automatic inspection device and can promptly respond to an emergency call.

[0008]

In order to achieve the above object, the present invention provides an inspection operation start command to a control device for controlling a car to perform an inspection operation of the car, and In an elevator equipped with an automatic inspection device for storing and transmitting to the monitoring center, the maintenance switch installed on the operation panel in the car is in the ON state, and the operation button installed on the operation panel is The controller is forcibly given the inspection operation start command when a predetermined operation is performed.

[0009]

According to the above-mentioned means, the maintenance staff can operate the operation panel from the inside of the car to give the inspection operation start command to the control device, so that it is not necessary to go to the machine room to operate the automatic inspection device. With it, the car can be inspected and operated, and operating status data and judgment data can be stored in the automatic inspection device as in the case of normal automatic inspection.If the hall call is registered, the car can be stored. The maintenance staff can immediately stop the inspection operation.

A hall call button 9 is provided in the elevator hall.

On the other hand, the control device 3 has a configuration in which a computing device 3a for computing operating state data is connected to an input / output device 3b for performing an input / output interface operation. , The output terminal of the hall call button 9, the output terminal of the rotary encoder 4, the car 6
The output terminals of various sensors and switches provided in the above, the input terminals of the motor 5, and the like are connected. Further, an automatic inspection device 1 described later is connected to the control device 3.

The automatic inspection device 1 stores the incorporated operating state data and determination data in the inspection control device 1b which receives various operating state data from the arithmetic unit 3a of the control device 3 and determines the operating state. The memory 1c and a communication device 1a for communicating with the monitoring center 2 are connected to each other, and the inspection control device 1b is connected to a connection point between the arithmetic device 3a of the control device 3 and the input / output device 3b. Has been done.

Next, a description will be given of an automatic inspection normally performed by the automatic inspection device 1 without a maintenance person.

At the scheduled inspection date and time preset in the memory 1c from the monitoring center 2 via the communication line 11, the automatic inspection device 1 is in a normal standby state when the elevator is operating according to the information from the control device 3. After confirming that there is,
The inspection control device 1b generates an inspection operation start command, and in response to this command, the control device 3 starts the inspection operation of the car 6. It should be noted that such an automatic inspection needs to be performed during a time period when the elevator is rarely used so as not to inconvenience users. Then, during the inspection operation of the car 6, detection signals from sensors and switches provided at various places are taken into the inspection control device 1b of the automatic inspection device 1, and based on the detection signals, the operating state data of the elevator and the determination are made. As the data is calculated, these data are stored in the memory 1c.
Stored in the elevator, it is possible to grasp the change tendency of the operating state of the elevator over a long period of time.

Further, since the operation state data and the judgment data thus stored are transmitted to the monitoring center 2 through the communication line 11, if it is deemed necessary in the monitoring judgment at the monitoring center 2, a periodic inspection is carried out. The maintenance staff can be dispatched to the site to make adjustments when necessary.

As described above, in an emergency elevator installed in a hospital or an elevator in a multi-tenant building that operates almost 24 hours a day, it is not preferable to perform automatic inspection without maintenance personnel. A maintenance worker will be dispatched to the site and the inspection will be performed according to the flowchart shown in FIG.

That is, in this case, a maintenance worker who goes to the site gets into the elevator car 6 and first operates the maintenance switch 7f of the operation panel 7. In this way, when the ON state of the maintenance switch 7f is confirmed in step 1 of FIG. 2, the process proceeds to step 2 of FIG. 2 and waits until a predetermined operation command preset in the memory 1c is generated from the operation panel 7 and then predetermined. When the driving command of is confirmed, the process proceeds to step 3 in FIG. In this embodiment, as the operation command, a command generated when the door open button 7a and the car call button 7d are simultaneously pressed for 1 second is adopted. When it is confirmed in step 3 that the elevator is operating normally, the process proceeds to step 4 in the figure, where the number of registered elevator calls, that is, the number of registered car call buttons 7c to 7e and the hall call button 9 are displayed. Wait until the number of registrations by and becomes 0. In this way, when it is confirmed that the number of registered elevator calls is 0, the process proceeds to step 5 in FIG.
The inspection operation start command is forcibly given to the car and the car 6
Starts inspection operation.

During the inspection operation, the hall call button 9
When is pressed and the call is registered in the elevator, the maintenance staff immediately interrupts the inspection operation, so that the car 6 can go straight to the floor where the call is generated.

As described above, in the above embodiment, the maintenance worker can give the control device 3 a command to start the inspection operation by performing a predetermined operation of the operation panel 7 including the maintenance switch 7f from the inside of the car 6. The inspection operation of the car 6 can be easily performed without going to the machine room and operating the automatic inspection device 1, and the inspection operation can be interrupted immediately when the call is registered. Therefore, the inspection for the elevator, which cannot perform automatic inspection without maintenance personnel,
It can be easily done without causing any inconvenience to users,
Since the operating condition data and the judgment data can be stored in the memory 1c of the automatic inspection device 1 as in the case of the normal automatic inspection, it is possible to grasp the change tendency of the operating condition of the elevator over a long period of time, and refer to this for effective operation. It is possible to perform highly efficient maintenance and inspection work. The above embodiment also has an advantage that a maintenance person can confirm the inspection operation from inside the car 6.

The predetermined operation of the operation panel 7 for giving an inspection operation start command from the car 6 to the control device 3 is as follows.
By combining the ON operation of the maintenance switch 7f with some ON operations of the operation buttons 7a to 7e, it is possible to appropriately set other than the above embodiment.

[0023]

As described above, in the automatic inspection mechanism according to the present invention, the maintenance operation of the car can be easily performed by the maintenance personnel performing a predetermined operation of the operation panel including the maintenance switch from inside the car. It can be performed and the operating status data and judgment data can be stored in the automatic inspection device,
