Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator inspection device in which the initial operation data of the equipment part which is the object of maintenance work is rewritten with new initial operation data after the maintenance work.

[0002]

2. Description of the Related Art Elevator performance is measured by the maintenance personnel during maintenance operation and performance measurement of parts and equipment performed during maintenance work.
If the elevator performance is judged to be comprehensively judged based on the experience of the operation of each part as perceived by the passengers and the riding comfort felt by the passengers during operation, adjustment of the equipment and replacement of the parts Maintenance work is performed. Periodic inspection work by maintenance personnel is necessary in order to quantitatively determine this deterioration in elevator performance and take appropriate measures. However, it is difficult for a limited number of maintenance personnel to increase the frequency of regular inspection work, while from the perspective of operating services for passengers, the downtime of the elevator for inspection work should be reduced as much as possible. There is a demand to want.

In view of the current state of inspection of elevators, Japanese Patent Laid-Open No. 1-252479 stores initial operation data at the time of installing equipment around an elevator door, and stores the initial operation data and operation data during operation. There is disclosed an apparatus for automatically checking the devices around doors by constantly comparing and, and when the difference exceeds a preset judgment value, an abnormality is reported.

[0004]

By the way, when maintenance work is performed on an elevator to adjust equipment or replace parts, the initial operation data of the equipment or parts is the same as the initial operation data before execution of maintenance work. Will be slightly different due to subtle differences in the installation status and aging. Therefore, in the elevator inspection device as described above, the initial operation data after the maintenance work is stored for each of the devices and parts that are the target of the maintenance work, and thereafter, for the devices and parts, It is desirable that the inspection operation be performed using the new initial operation data.

However, in the disclosed device, when the initial operation data of the equipment subject to the maintenance work is rewritten to the new initial operation data after the maintenance work, the stored equipment which is not the subject of the maintenance work is stored. All initial operation data will be lost. Therefore, if the initial operation data of the equipment that has undergone maintenance work is to be rewritten, the initial operation data of all other equipment must be rewritten at the same time, which requires considerable time and effort.

The present invention has been made in view of the current state of the elevator inspection of this kind as described above, and the purpose thereof is to rewrite only the initial operation data of the equipment which is the object of maintenance work. To provide an elevator inspection device.

[0007]

In order to achieve the above object, the present invention stores initial operation data when an elevator is installed and compares the operation data during operation with the initial operation data to inspect the elevator. In the elevator inspection device that performs the, after the maintenance work is performed on the elevator, input means for inputting the maintenance work items performed, and a determination means for determining the initial operation data that needs rewriting for the input maintenance work items, The operation data setting means for rewriting the initial operation data determined to be necessary to be rewritten by the determination means with the operation data measured after the maintenance work and setting new initial operation data is configured.

[0008]

With this configuration, when maintenance work is performed on the elevator, when the maintenance work item that is performed is input by the input means, the initial operation data that needs to be rewritten corresponding to the maintenance work item by the determination means. Is determined. Therefore, when the operation data corresponding to the initial operation data determined to require rewriting is measured after the maintenance work, the operation data setting unit rewrites the initial operation data with the measured operation data, and a new initial operation is performed. The data is set.

It also has a function of outputting a lock signal from the switch DS.

The door opening / closing inspection device 3 connected to the operation control device 2 has an operation time measuring circuit 31 for measuring the operation time between the signals output from the communication interface 25 which are set in advance. , Operating time measuring circuit 31
There is provided a measurement memory circuit 32 for storing the measured value of 1 and an initial value memory circuit 33 for storing the initial measured value of the operation time measuring circuit 31 at the time of installing the elevator. further,

And a judgment storage circuit 35 for storing the judgment data of the comparison judgment circuit 34. The operation time measurement circuit 31 and the measurement storage circuit 32 are connected to the communication interface 25, and the operation time measurement circuit 31, the initial value storage circuit 33, and the comparison determination circuit 34 are connected to the measurement storage circuit 32. The comparison determination circuit 34 is connected to the initial value storage circuit 33 and the determination storage circuit 35, and the determination storage circuit 35 is connected to the terminal device 4 and the display device 5.

On the other hand, the data rewriting device 6 carried by the maintenance personnel
Then, the initial value setting determination unit 62 that determines the operation data that requires rewriting of the initial operation data corresponding to the input item is connected to the input unit 61 to which the item of the maintenance work performed by the inspector is input. The initial value setting determination unit 62 is connected to an initial value setting unit 64 that issues an initial value setting command and an initial operation data storage unit 63 that stores initial operation data.

Next, the operation of the embodiment having such a configuration will be described.

In the embodiment, the operation data used for inspecting the equipment around the elevator door is the ON / OFF timing time of the signal related to the opening and closing of the door. That is, as shown in FIG. 2, in the embodiment, when the elevator door is opened,
At the time point CET, the logical value of the door opening command signal ZOPEN becomes "1", after a time point a0 from the start time point CET of this opening operation, the logical value of the full-closed detection signal XCLS becomes "0", and after the time points a0 to a1 the fully opened state. Detection signal XOLS
Becomes a logical value of "1". Also, from time a0 to time a2
Later, the logical value of the car door switch signal XGS becomes "0", and the logical value of the hall door lock switch signal XDS becomes "0" after the time a0 to the time a3. In this case,
At time CET, the elevator door is fully closed, and at time OET, the elevator door is fully open.

In the embodiment, these times a0, a1, a2, and a3 are set when the elevator is installed, and the operating time measuring circuit 3
1 and stored in the initial value storage circuit 33 as initial operation data. When storing the initial operation data, the elevator doors are opened and closed once for each floor, and the measured values of time a0 to a3 for each floor are stored in the initial value storage circuit 33 together with the initial value setting completion flags. Store. In this case, if the number of times the elevator doors are opened and closed on each floor is set to multiple times and the average value of each of the measured values of the times a0 to a3 of each time is stored as the initial operation data, the determination accuracy based on these initial operation data is improved. Can be made. In addition, the measured values of the times a1 to a3 may be different for each elevator, and even in the same elevator, there may be differences due to differences in specifications of the hall doors for each floor.

In the embodiment, during normal operation, the operation time measuring circuit 31 measures the time a0 to a3 each time the elevator door is opened and closed as the car 1 is operated, and the measured value is stored in the measurement storage circuit 32. It Then, the comparison / determination circuit 34 allows the measurement storage circuit 32 and the initial value storage circuit 33.
From the above, the measurement data of times a0 to a3 corresponding to each other are read out and compared with each other. If there is a difference between the predetermined values set in advance, it is determined as abnormal. This time a0
By monitoring the change of a3 by the comparison and determination circuit 34, "increase in running resistance value of the hall door", "increase in running resistance value of the car door", "change in entry position of the car door switch GS", and "landing door lock switch DS". Change of input position
Check for maintenance work items such as "change in the closing position of the fully closed detection switch CLS", "change in the closing position of the fully open detection switch OLS", "clogged car door", "abnormality near the closed end of hall door", etc. be able to.

When the comparison / determination circuit 34 determines that there is an abnormality, the inspection date / time data, the abnormality detection code for displaying the content of the abnormality, the floor name data, the measurement data at times a0-a3, and the times a0-a3. The initial operation data is stored in the determination storage circuit 35. Then, the various data stored in the determination storage circuit 35 are periodically transmitted, for example, once a month to the monitoring center of the elevator maintenance company via the terminal device 4. Therefore, the monitoring center of the elevator maintenance company analyzes the transmitted data and dispatches maintenance personnel to the elevator installation site for maintenance work on defective equipment.
Perform maintenance work such as adjusting defective devices and replacing parts.

In this case, for example, if an abnormality such as "change in the loading position of the landing door lock switch on the third floor" is detected, the maintenance personnel inspects the area around the door lock switch on the third floor, and the door lock switch is checked. If the contact is severely abraded, the door lock switch is replaced with a new one, and after the replacement is confirmed that the door opening / closing operation is normally performed, the maintenance work is completed. Due to this maintenance work, the operating time of each switch at the time of opening and closing the elevator doors becomes the normal value, but it is not possible to install the replaced 3rd floor hall door lock switch in exactly the same state as before the replacement, and it also changes over time. Therefore, the initial operation data of the door lock switch is different from the initial operation data when the elevator is installed, which is stored in the initial value storage circuit 33.

Therefore, in the embodiment, the maintenance person connects the portable data rewriting device 6 to the door opening / closing inspection device 3,
As a maintenance work item performed by operating the input unit 61, “3
Enter the input data of "Replace door lock switch on the floor". By inputting the input data, the initial value setting determination unit 6
2 operates to retrieve the initial operation data corresponding to the input data of “replacement of door lock switch on the third floor” from the initial operation data storage unit 63, and detects the fully closed detection signal XCLS on the third floor.
It is determined that it is necessary to rewrite the initial operation data at the time a3 from when the logical value of is 0 to the logical value of the hall door switch signal XDS. And
In response to a setting signal from the initial value setting section 64, the initial value storage circuit 33 is set to the reset state, and the initial value setting completion flag at the time a3 on the third floor is cleared.

In this state, when the maintenance staff moves the car 1 to the third floor and opens and closes the elevator door in the hall on the third floor, the operation time of each operation time measured by the operation time measuring circuit 31 is corresponding to this opening and closing. In the initial value storage circuit 33, only the operation time a3 is rewritten and stored as initial operation data. Therefore, the initial operation data of the operation time a3 corresponding to the exchanged door lock switch of the third floor hall is:
For the equipment and parts that have been overwritten by new initial operation data and the determination of abnormalities that occur thereafter is highly accurate, and are not the target of maintenance work, the initial operation data written when the elevator was installed The abnormality is appropriately determined as usual.

As described above, according to the embodiment, the initial operation data is rewritten only for the equipment that has been adjusted and replaced by performing maintenance work. Therefore, when the equipment is adjusted or replaced, a simple operation is performed. Thus, the latest initial operation data for each equipment can be stored in the initial value storage circuit 33 in a short time, and the subsequent abnormality inspection of the members can always be performed with high accuracy. For this reason, while performing maintenance work,
Even for an elevator that has been used for many years, it is possible to detect abnormality in each member with high accuracy, and maintain a safe and comfortable operating state of the elevator.

In addition, in the embodiment, the case where the maintenance and inspection of the equipment around the door of the elevator is performed is described, but the present invention is not limited to the embodiment, and the initial operation data and the current operation data are compared. It can be applied to any equipment that determines abnormality by means of, for example, it is also possible to inspect the running state of an elevator.

[0025]

As described above, according to the present invention, the operation data that needs to be rewritten is determined for the equipment that is the object of maintenance work, and the operation data that is determined to be rewritten is measured. Since the initial operation data of the equipment is rewritten by the operation data, even if maintenance work is repeated, the abnormality of the equipment is constantly checked with high accuracy based on the latest initial operation data, and the elevator can be operated for a long time. It is possible to maintain a safe and comfortable driving condition for the whole time.
