DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance support apparatus, and more particularly, to a maintenance support apparatus which provides a means suitable for determining a device to be the main maintenance work on a maintenance day.

[0002]

2. Description of the Related Art Generally, when a failure or abnormality occurs in equipment in a building, a maintenance support device automatically reports this information to a maintenance center at a remote location through a telephone line. This is an apparatus that can read out status data from a maintenance center and grasp the operation status of equipment at a remote location.

FIG. 3 is a system configuration diagram showing an example of a conventional maintenance support device, particularly an example of an elevator maintenance support device. In FIG. 3, B is a building, in which an elevator driving device 7, a car 9, a counterweight 8 arranged opposite to the car 9, a hall device 10, and an elevator control device 6 for controlling these components. And a terminal device 1 are provided. The terminal device 1 includes a CPU 2 serving as a central processing unit, a conversion device 4 for interfacing with the elevator control device 6, a storage device 5 for storing elevator status data obtained from the elevator control device 6 via the conversion device 4, and a telephone. The transmission device 3 is configured to interface with the line L. on the other hand,
C is a maintenance center, and the transmission device 11, the display device 12,
A CPU 13, an input device 14, a printing device 15, and a customer master file 16 stored in a storage device are provided.

[0004] The terminal device 1 constantly collects elevator status data via the conversion device 4, and the storage device 5 stores data indicating the occurrence of a failure, detection data of abnormality of each elevator device, and data of each elevator device. The integrated value of the number of operations is stored.

Next, the operation of the conventional elevator maintenance support apparatus will be described. When the terminal device 1 detects a serious failure such as “containment”,
Since an emergency response is required, this information is reported to the maintenance center C via the telephone line L by the transmission device 3. The maintenance center C receives this information by the transmission device 11, searches the customer master file 16, and displays and prints the customer name and the status of the elevator on the display device 12 and the printing device 15. This allows the operator of the maintenance center to take the necessary measures for the "closed" waist.

On the other hand, the items as shown in FIG. 4 in which the terminal device 1 detects an abnormality in each of the elevator devices are minor abnormalities. Not necessary. FIG. 5 shows an example of an item in which the terminal device 1 of FIG. 3 is measuring an integrated value of the number of times of operation of each elevator device, and a maintenance technician performs maintenance of the elevator together with the abnormal inspection item. This is for determining a device that requires an important adjustment operation when performing the operation.

Hereinafter, a method of determining the above-mentioned important adjustment work will be described. FIG. 6 shows the data structure of one customer in the customer master file 16 of the maintenance center shown in FIG. 3, and the customer code, customer name, elevator model, and maintenance center C assigned to each customer are stored in the terminal device 1.
The telephone number of the terminal device 1 for connecting the telephone line to the terminal device, the data indicating the detection date of abnormality of each elevator device stored in the storage device 5 of the terminal device 1 and the readout date of the integrated value of the number of operations of each elevator device Read date and time, previous terminal device 1
And the storage data of the integrated value of the number of times of operation of each elevator device read from the terminal device 1 this time.

The CPU 13 installed in the maintenance center C shown in FIG. 3 having the customer master file has a clock mechanism (not shown). The date and time always obtained from this clock mechanism and the date and time of the customer master file shown in FIG. The data read date and time are compared with each other, and if they match, the next processing is performed. That is, the CPU 13 controls the transmission device 11 to make a connection to the terminal device 1 via the telephone line L, and from the storage device 5 of the terminal device 1 via the transmission device 3 to each of the elevator devices shown in FIGS. And the integrated value measurement data of the number of times of operation of each elevator device are read out.
Next, the CPU 13 determines a customer master file portion corresponding to the corresponding customer in the customer master file 16 (FIG. 6).
) Is moved to the previously read data area, and the newly read data is stored in the currently read data area. Next, the CPU 13 prints the measurement data table shown in FIG. On the maintenance work day, the maintenance technician determines the equipment that requires intensive adjustment work based on the measurement data table. For example, in the case of the example shown in FIG. 7, since an abnormality of the landing level and an abnormality of the relay closing time are detected in the abnormality detection data, the priority adjustment devices are the landing mechanism of the elevator and the relay. In the measurement data, since the number of times of opening and closing the door and the number of times of intercom operation are large, it can be understood that this is also a priority adjusting device.

[0009]

By the way, in the above-mentioned conventional device, as shown in FIG.
The maintenance date is fixedly set according to the maintenance interval of each customer, and is not always always close to the actual maintenance date. This is because the maintenance date may be changed depending on the circumstances of the customer or the insurance company or various other conditions.

[0010] Therefore, if the data readout date is sometimes separated, even if the measurement data table shown in FIG.
The data itself is not the data according to the maintenance interval, that is, the data from the previous maintenance date to the current maintenance date, but rather old data. However, although there is already new abnormality detection data, there has been a problem that adjustment work to cope with this cannot be performed. Similarly, the accumulated data of the number of operation times of the device is also old, so even if the priority adjustment device is determined based on the number of operation times of the device, the number of operation times of another device will be different on the actual maintenance date. In some cases, it was not possible to determine the optimal priority adjustment device.

An object of the present invention is to solve the above-mentioned problems in the prior art and to provide a maintenance support apparatus capable of determining an optimum priority adjustment work item on a maintenance day.

[0012]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a terminal device for collecting and storing data on each of predetermined equipments in a building, and a data device stored in the terminal device. And a maintenance center that reads out the maintenance date via a communication line, a storage unit for storing the current maintenance date in the maintenance center device, and a maintenance date stored in or near the maintenance date stored in the storage unit. Selecting means for selecting a date; and reading means for reading the data stored in the terminal device on the selected day when the date selected by the selecting means is reached. .

[0013]

When a maintenance date is determined based on an interval according to a maintenance contract with a customer, the maintenance work date is stored in the storage unit. Thus, the selecting means selects the date and time when the data is read from the terminal device or a date near this date, and stores the data which is the day before the maintenance work date in the customer master file. The CPU compares the date and time obtained from the clock mechanism with the data read date and time in the customer master file,
If they match, the required data is read from the storage device of the terminal device. The read data is printed. On the work day (the next day), the maintenance technician determines a device that requires intensive adjustment work based on the printed data.
