[0002]

2. Description of the Related Art Conventionally, elevators have been inspected by a maintenance person who regularly patrols the operating state of each part of the elevator visually or by using a measuring instrument. However, in this conventional inspection method, since the diagnosis of the operating state of each part of the elevator is performed by individual differences in inspection results due to differences in judgment based on measurement techniques and experience of maintenance personnel, parts replacement performed based on the inspection results is performed. In some cases, elevators and maintenance work are wasted when they are not needed, and conversely, elevators may be broken down because parts are left without replacement or maintenance work.

Therefore, an inspection apparatus for an elevator for efficiently performing an inspection with high diagnostic accuracy in accordance with the use environment of the elevator, the operation history, and the characteristics of each apparatus has been disclosed in Japanese Patent Laid-Open No. Hei 1-228.
No. 85 has proposed this. This elevator inspection device connects a sensor and a microcomputer having an automatic inspection function to a control device that controls the operation and inspection of the elevator,
Also, the maintenance procedure program for the elevator is stored in the storage device of the portable terminal device carried by the maintenance personnel, and the microcomputer having the automatic inspection function and the portable terminal device are connected by a communication cable. To perform an inspection operation automatically by issuing an inspection operation command in accordance with the inspection procedure in the storage device. As a result of this automatic inspection, sensor abnormality detection data, measurement operation data, inspection limit value data, etc. are imported to the portable terminal device, and the collected data is taken back to the office, transmitted to the host computer, and replaced for each elevator. The timing of adjustment, etc. was determined efficiently with high diagnostic accuracy.

[0004]

However, the conventional elevator inspection apparatus can perform the operation according to a pre-programmed inspection procedure, but when the inspection operation has to be interrupted for unavoidable reasons. However, since the procedure for returning the elevator to the normal operation state is not taken into account, the maintenance staff has to manually return to the normal state. In addition, since a sensor and a microcomputer having an automatic inspection function are required, and coordination with a host computer is necessary, the system becomes a large-scale system, and is not suitable for work such as countermeasures for a relatively small accident that has occurred unexpectedly.

[0005] It is an object of the present invention to provide a maintenance work support apparatus capable of coping with a return when an inspection is interrupted.

[0006]

FIG. 2 is a flowchart showing the operation of the above-mentioned maintenance work support device.

First, in step S1, the work instruction data 11
Are displayed in a list on the screen display unit 12, and the maintenance staff selects the key operation unit 1 from the list.
By the operation 3, work instruction data corresponding to the work to be performed is selected. In step S2, instruction data corresponding to the selected operation is extracted from the operation instruction data 11. Here, if the electromagnetic brake operation diagnosis is selected, the contents shown in FIG. 4 are displayed.

FIG. 4 shows an example of data registered as work instruction data. The work instruction data is used as screen display data, and a work item 11a in which an outline of each work is registered, and a work method 11a. 11b in which operation guidance of the mobile terminal device 1 and the like are registered, a button 11c for displaying on the screen and performing an operation, and a command 1 of communication data to be transmitted to the elevator according to the operation.
The work consists of four items 1d and is performed in order from the one shown in the first line of the work content 11b. The operation guidance for inspection and diagnostic work includes a detailed description of a series of tasks from the start to the end, such as the elevator preparation procedure before work, the actual inspection and diagnosis procedure, and the elevator return procedure after inspection and diagnosis. It has been described.

The work instruction data extracted and displayed in step S2 as shown in FIG. 2 is temporarily stored in the work instruction data storage unit 15 in step S3. Next, in step S4, the work instruction data translating unit 16 reads out the work instruction data in order from the first row based on the work instruction data stored in the work instruction data storage unit 15, and stores the outline of each work, the work item 11a, the work method, and the mobile phone. The work content 11b in which the operation guidance of the terminal device 1 is registered is processed as screen display data. At this time, a button name and its processing are defined for the button 11c so that the button can be operated according to each work content.

Thereafter, the data processed as screen display data in step S5 is used as a work procedure in the screen display unit 12
And the operation buttons are displayed on the screen as operable buttons. In the following step S6, the worker reads the work name and the work guidance displayed on the screen display unit 12, actually performs the work in accordance with the work guidance, and presses the operation button displayed according to the work content after the work is performed. Proceed with the work.

FIG. 3 is a flowchart showing in detail the processing procedure of step S6 shown in FIG.

In step S61, the work item 11a, work content 11b, and button 11c previously processed by the work instruction data translating unit 16 are displayed on the screen display unit 12 via the control unit 17, and the button 11c is displayed on the screen. In addition to the display, a predetermined process is associated as a process when the button is pressed, such as "Next" for the "OK" button, "Interrupt the process" for the "No" button, and the like. Here, as shown in FIG. 4, the work content 11b includes a case where the elevator is directly operated, for example, as in the guidance of "Please perform a dedicated operation in the car (turn on the check light SW)". By operating the key operation unit 13 of the mobile terminal device 1 as in the guidance of “Set the machine room low-speed operation mode. Are you sure?”, The mobile terminal device 1 issues a communication data command to the elevator. Two types are provided, one for issuing and operating the elevator.

Next, in step S62, the operation guidance displayed on the screen display unit 11 is confirmed, the operation is performed according to the guidance, and after the operation is completed, the button 11c is selected according to the operation button. In addition, when the guidance of “I drive to the middle floor at high speed. Are you sure?” Is displayed in the work content 11b, after confirming the guidance, press the “OK” button of the normal button 11c.
Since "MODE5 SET" is registered in 1d, the button 11c is transmitted to the communication control unit 23 of the elevator 2 via the communication control unit 14 at the same time when the button 11c is pressed. Here, the data to be transmitted is “MODE”, “5”, “SET”
Is converted into unique control data and transmitted.

The control data received by the communication control section 23 of the elevator 2 is transmitted to the maintenance work operation instructing section 22,
The operation instruction unit 22 for maintenance work receives the control data,
When the operation instruction unit 22 for maintenance work issues an operation command to the operation control unit 21, the operation control unit 21 actually operates the elevator. The work performed in this manner is recorded in the processing history storage unit 18 via the control unit 17 in step S63.

Next, in step S64, the control unit 17 checks whether all the operations registered in the operation instruction data have been performed.
It is determined whether it is still in the middle of work, and if it is in the middle of work, it is determined in step S65 whether or not the worker is performing an interruption operation from the key operation unit 13, and if not, the process returns to step S61. Proceed to the next task. However, when the work is performed to the end of the work instruction data, it is determined in step S64 that the work has been completed, and the work is completed.

If it is determined in step S65 that the worker has performed the interruption operation, the work history up to the present time is read from the processing history storage unit 18 in step S66.
In step S67, in order to return the state of the elevator to the original normal state, operation guidance is displayed so that the reverse operation is performed so as to return to the original operation in order from the latest completed operation. As can be understood from this description, when the operation for interrupting the operation is performed by the key operation unit 13 which is the input means, the operation is performed in such a manner that the latest completed work in the processing history storage means 18 is returned in order. Return guidance display means for displaying work guidance for proceeding with the operation.
If the operation is performed in step S68 according to the guidance displayed by the return guidance display means, the state of the elevator can be returned to the state before the start of inspection.

As described above, the inspection work and the diagnosis work are displayed on the screen display unit 12 with the elevator preparation work procedure before the work and the operation guidance of the actual inspection and diagnosis procedure, and the elevator is returned to the original state after the predetermined operation. The return guidance display means for displaying the operation guidance of the return procedure on the screen display unit 12 for returning to the state of operation is provided, so that a series of operations can be smoothly performed only by proceeding with the guidance, and highly accurate inspection and diagnosis work can be performed. Even when the inspection work must be interrupted, the elevator can be quickly returned to a normal state by proceeding according to the guidance of the return procedure by the return guidance display means. In addition, since the inspection work and the diagnosis work to be performed are selected, it is possible to cope with relatively small work such as troubleshooting.
