DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator repair plan creating apparatus used by an operator to repair an elevator.

[0002]

2. Description of the Related Art Elevators and escalators (elevators) are generally used by a large number of people, so that when a failure occurs, not only does the person who uses the elevator suffer a great deal of inconvenience, but in extreme cases, it can lead to personal injury. There is a risk. Therefore, strict maintenance is required for these elevators.

An elevator is composed of a number of parts, each of which has a specific service life or a permissible running time (permissible use value). Exceeding these causes the function of the part to deteriorate or cause a failure. The chances of an accident increase, eventually leading to an elevator accident. To prevent this, diagnose and replace (repair) each part at the appropriate time.
Need to be done.

[0004] Such repairs require specialized knowledge and are usually entrusted to a maintenance company that performs the repairs. Then, the maintenance company dispatches a technician to the managed elevator to perform maintenance and repair. In this case, since the number of elevators to be managed is large, and the number of parts constituting one elevator is also large, the number of parts to be repaired reaches an enormous number. Is
A proper repair plan is required.

[0005] This repair plan will be described for an elevator. The maintenance company accumulates, as data, parts items (repair items) to be repaired for each elevator model, useful life or permissible running time for each repair item, and also records repairs. Therefore, a person in charge of repair plan creation (for example, a person designated for each group of each sales office of the maintenance company) retrieves the above data and repair results for all elevators managed by the own group, and The management ledger for the year is created once a year with reference to the inspection report. The format of this management ledger is created according to the repair policy of the person in charge of repair planning, so it differs for each person in charge, but at a minimum, the items to be repaired in this fiscal year and the due date are listed for each elevator. Become. A technician is dispatched to each elevator according to the repair plan created in this way to perform repair.

Incidentally, the management ledger is created by hand by a repair plan creator by referring to the data, the repair record, and the periodic inspection report. By the way, although the repair items of the elevator managed by one group of each sales office vary depending on the elevator model, one elevator has 150 to 2 items.
Since there are 00 items, the total number of items to be repaired is enormous. Therefore, creating a management ledger requires not only a great deal of labor and time, but also a lot of errors and it is not reliable enough. The applicant of the present invention has proposed a repair plan creating device for an elevator capable of accurately and easily creating a repair plan and contributing to reliable operation of the elevator in Japanese Patent Application No. 149596/1992. did.
The proposed device will be described with reference to the drawings.

In the figure, reference numeral 11 denotes a host computer, an arithmetic control unit 11a for performing various processes in accordance with predetermined procedures, a storage unit 11b for storing various data necessary for creating a repair plan, and a storage unit for storing the created repair plan. 11c and a table creation unit 11d for creating a required table under the control of the arithmetic control unit 11a. The storage unit 11b stores models corresponding to the numbers of all elevators, repair items for each model (each model has a different configuration, so repair target parts are different, and repair items are different). In addition, a repair interval and a permissible traveling time set in consideration of the secular change, functional deterioration, service life, and the like are stored. Also, table creation unit 11d, repair plan table creating unit 11d _1, is constituted by the remaining list creating unit 11d _2, and the amount of work list creation section 11d _3.

Reference numeral 12 denotes a terminal computer provided at each sales office, a control unit 12a for performing various processes in accordance with predetermined procedures, an input unit 12b for inputting required commands,
And a display unit 12c. The main configuration of each terminal computer 12 at each sales office is the same.

Next, the operation of the above apparatus will be described with reference to a flowchart shown in FIG. 4 and a repair plan table shown in FIG. The maintenance company first creates a repair plan table for all elevators managed by itself, stores them in the storage unit 11c, and thereafter, the repair plan table created by each sales office or a group of business offices is: It is created by extracting a required repair plan of the elevator from the repair plan stored in the storage unit 11c.

[0010] First, creation of a repair schedule table to be stored in the storage unit 11c will be described. The numbers of all elevators are input to the host computer 11 one by one.
When the elevator number is input (procedure S ₁ shown in FIG. 4), the arithmetic control unit 11a of the host computer 11 reads, from the storage unit 11b, each repair item of the model of the elevator with the number,
For those that are set repair intervals in each repair item out taking the repair interval, respectively (Step S ₂ ~
S _4).

Furthermore, the operation control section 11a, taken out the accumulated travel time of the elevator from the storage unit 11b (Step S _5), then out also taken if the previous repair implementation date (last implementation date) (Step S ₆ ). Next, for a repair item having a repair interval, a scheduled repair date is calculated based on the previous execution date of the repair item and the repair interval. to calculate the repair scheduled date (this time planning date) based on the travel time (Step S _7). Table creation unit 11d, the input elevator number, taken Desa the last execution date, and using the computed current planning date to create a repair plan table for the elevator (to be described later) (Step S _8). The created repair plan table is stored in the storage unit 1.
Stored in 1c (Step S _9).

FIG. 5 shows the number 1 stored in the storage unit 11c.
A repair schedule for the elevator 23456-01 is displayed. "Work name" in the figure corresponds to the repair item. "H" indicates that the repair interval has been set, and "O"
"Diagnosis and repair" means "upper and lower" means the first and second half of a year.

A repair schedule table shown in FIG. 5 is created for all elevators, and these are stored in the storage unit 11c.
Control unit 11a of the host computer 11 waits for the input of elevator numbers (Step S _10). Here, in order to create a repair plan of the elevators managed by the own team, the workers belonging to the group having the maintenance work of the sales office sequentially input the numbers of the respective elevators using the input unit 12b of the terminal computer 12. Then, according to the input of the elevator number, the arithmetic and control unit 11a extracts the repair plan table of the elevator from the storage unit 11c,
And transmits to the terminal computer 12 (Step S _11). Then, it waits for input of the data of the previous embodiment from the terminal computer 12 to be described later (Step S _12).

On the other hand, the terminal computer 12 stores the sent repair plan table in the display unit 12 under the processing of the control unit 12a.
c. The displayed contents are the same as those shown in FIG. 5, but in addition to this, the name of the building where the elevator is installed, the type of maintenance contract, the entity that performs the work on each repair item (whether the maintenance company or the outside company), etc. Required data can be added.

The worker looks at the screen displayed on the display unit 12c and checks whether or not there is a repair record for each repair item.
If there is a repair record, enter the repair date in the “Last implementation” section. The repair date data is transmitted to the host computer 11, and a new scheduled repair date is calculated based on the data (step S ₁₃ ).
And changes the date in the section of “this plan” to the date newly transmitted. In this way, when the processing of the repair plan table for the elevator is completed, the operator inputs data indicating the end using the input unit 12b. Operation control unit 11a of the host computer 11 uses the date calculated by the date of repair and procedures S ₁₃ of the input previously "previous embodiment",
Update the repair plan table of the elevator, which is stored in the storage unit 11c (Step S ₁₄₎ and stores it in the storage unit 11c (Step S _9).

In the above processing, when the repair schedule table is transmitted from the host computer 11 and the data of the repair interval and the permissible travel time for each repair item are transmitted together, the calculation of the scheduled repair date is performed by the terminal computer 12.
In this case, all data is transmitted to the host computer 11 when the correction of all repair items is completed. The host computer 11 so that the these data updating repair plan table of the elevator in the processing of steps S _14.

As described above, in the above-described apparatus, the repair plan table is stored in the host computer in advance, and is taken out when necessary to update the necessary items, so that the repair plan table can be easily, quickly, and accurately. Can be created.

[0018]

The storage unit 11
In b, various data such as repair items of all elevators, repair intervals, cumulative running time on the previous day, and the like are stored. These data increase dramatically according to the increase in the number of elevators to be managed. In this case, the number of storage units and thus the occupied area increase.

An object of the present invention is to solve the above-mentioned problems in the prior art and to provide a repair plan creating apparatus for an elevator capable of reducing the storage capacity of a storage unit.

[0020]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to an elevator repair plan creating apparatus which determines a repair plan of a repair target portion for a large number of elevators. A first storage unit for storing a repair item for each model, a repair interval determined for a predetermined repair item among these repair items, and an allowable use limit value for the repair item of each elevator; And a repair interval having a predetermined relationship with a repair interval or a permissible limit value of a specific repair item among the repair items stored in the storage unit is stored together with the predetermined relationship. And a first calculating means for calculating a scheduled repair date of each repair item of the elevator based on data stored in the first storage unit for the designated elevator, Determining means for determining whether or not there is an associated repair item stored in the second storage unit for the repair item whose scheduled repair date is determined by the first arithmetic means; and Second calculating means for calculating the associated scheduled repair date based on the predetermined relation to the repair interval or the allowable limit value of the specific repair item when it is determined that the repair item exists; and each repair of each elevator. A third storage unit for storing the scheduled repair date calculated by the first calculation unit and the second calculation unit for each item, and stored in the terminal computer in the third storage unit; Readout means for reading data of an arbitrary elevator among the data, readout means for displaying the data read out by the readout means, and input means for inputting the repair performance of the designated elevator. The host computer, characterized in that a data updating means for updating the data stored in the third storage unit based on the repair record input by the input means.

[0021]

The host computer gives a scheduled repair date for each repair item of each elevator and stores them in the first storage unit. When a certain elevator is repaired, for example, when the number of the elevator is input to a terminal computer provided in a business office that manages the elevator, data of the elevator is retrieved from the first storage unit. Next, when the repair record (repair date) is entered in the terminal computer,
The repair record is sent to the host computer, and the host computer calculates the scheduled repair date based on the repair record, and updates the scheduled repair date of the elevator stored in the first storage unit. Since such processing is performed every time the repair is executed, accurate data is always stored in the first storage unit. Therefore, when the desired elevator number is input to the terminal computer, the correct repair schedule date is displayed on the display means for each repair item. When an associated repair item having a predetermined relationship with a certain repair item is stored in the second storage unit, a scheduled repair date is calculated for the associated repair item based on the predetermined relationship.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a block diagram of an elevator repair plan creation apparatus according to an embodiment of the present invention. In this figure, the same or equivalent parts as those shown in FIG. Reference numeral 11e denotes a storage unit corresponding to the storage unit 11b shown in FIG. 3, and 11f denotes a storage unit storing only a repair item having a specific relation to a certain repair item stored in the storage unit 11e and only the specific relation. Yes, various data of each repair item in the storage unit 11e is not added. The repair items stored in the storage unit 11f are stored in the storage unit 11f.
e is not stored.

Here, the relationship between a certain repair item stored in the storage unit 11e and a repair item stored in the storage unit 11f will be described. For example, when raising or lowering the elevator car, first, a motor start control relay, a rising detection relay in the case of ascent, a descent detection relay in the case of descent, and the motor operates to move the car. . In the case of ascending or descending in this way, the motor starting relay always operates. Looking at the relationship between the motor starting control relay (referred to as a main relay), the ascending detection relay, and the descending detection relay (referred to as associated relays), it can be seen that, due to the structure of the elevator, the main relay The number of actuations is twice the number of actuations of each associated relay. Therefore, the life of the main relay is の of the life of each auxiliary relay when the current capacity of both auxiliary relays is approximately equal to that of each auxiliary relay.

If the number of replacements from the scheduled repair date and the delivery date (installation date) of the main relay is known,
Based on the above, the scheduled repair date of the associated relay is automatically determined. In addition to the above-mentioned relays, there are many such associations, such as an elevator car door relay (main relay), a door opening direction detection relay, and a door closing direction detection relay (each associated relay). Storage unit 11 shown in FIG.
In f, the repair items having the above relation are stored, and the remaining repair items obtained by deleting these repair items from the storage unit 11b shown in FIG. 3 are stored in the storage unit 11e.

Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG. In this embodiment, steps S ₁ to
Processing of S ₇ are the same as the processing in steps S ₁ to S ₇ shown in FIG. In Step S _7, the calculation of the current planning date of a repair item is finished, the arithmetic control unit 11a is the repair item, whether there is a repair item associated, i.e., As far the example of previous relays associated It is determined whether there is a relay (step _S71 ). The result of this determination, removed, if any repair item associated, the service life of the relationship between the repair (replacement) number and the repair item of the repair item which is calculated in step S _7, the current plan repair items associated The day is calculated (step _S72 ).

For example, if the repair item is a motor start control relay and its replacement interval is one year, and the associated repair item is a rise detection relay, the replacement interval of the rise detection relay is the motor start control relay. since the two years preceding the context of the relay, the motor start current control relay planning date (replacement planning date) is determined in step S _7, the current planning date is at even-numbered planning date rise this time planning date for the detection relay (replacement plan date) is the date after two years of the date that has been determined in step S ₇ in the case. If the current planned date of the motor start control relay is an odd number, the current planned date of the ascending detection relay is not calculated. The subsequent processing procedure is the same as the procedure of the previous embodiment.

As described above, in the present embodiment, for a repair item having a specific relationship with a certain repair item, addition of predetermined data accompanying the repair item is omitted, and only a specific relationship is added. Therefore, the storage capacity of the storage unit can be reduced.

Note that the allowable use value is outside the allowable travel time,
Other indices, such as the number of uses, can also be used.

[0029]

As described above, according to the present invention, for a repair item having a specific relationship with a certain repair item, addition of predetermined data associated with the repair item is omitted, and only the specific relationship is added. Since it is added, the storage capacity of the storage unit can be reduced.
