JPH0528160A - Maintenance schedule control system - Google Patents

Abstract

PURPOSE:To automatically produce a maintenance schedule necessary for the building control by fetching the operating state data on the equipments set at a work site in an on-line way and using a computer for production of the maintenance schedule. CONSTITUTION:A monitor control computer 1 controls the site equipments 3-1-3-3 provided in a building to record the operating time of each equipment and to store the operation data necessary for the optimum maintenance of the equipments 3-l-3-3 A maintenance schedule control computer 2 fetches the operation data stored in the computer 1 in a fixed cycle through a transmission line 4 and automatically produces a maintenance schedule. Thus no man power is needed at all for collection and application of data and furthermore the accurate information is obtained. In such a constitution, a proper maintenance schedule is automatically produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance schedule management system, and in particular, field conditions such as an air conditioner installed in a building such as a building to secure a living environment, and evaluation conditions such as an operating cost and a service life. The present invention relates to a maintenance schedule management method for managing creation of a maintenance schedule for optimal maintenance based on the above.

[0002]

2. Description of the Related Art Conventionally, this type of maintenance schedule management system has been designed such that an administrator visually confirms and records the operation status data of field equipment required for creating a maintenance schedule, and then records it on an input terminal such as a keyboard or bar code reader. It was a method of operating by using an offline type computer, that is, manually input using.

[0003]

In the above-mentioned conventional maintenance schedule management method, since the administrator intervenes in all of the operation status data collection and data entry required for creating the maintenance schedule, the misidentification at the time of visual confirmation, There is a drawback that a proper maintenance schedule cannot be created due to human factors such as data omissions and input errors when data is input.

An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a maintenance schedule management system which eliminates error intervention due to human factors.

[0005]

A maintenance schedule management system of the present invention is a maintenance schedule management system for managing creation of a maintenance schedule set for optimal maintenance of equipment installed in a building. The operation status data acquired by a computer for monitoring and controlling the above is periodically taken online into a maintenance schedule management computer, and a maintenance schedule is automatically created.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment shown in FIG. 1 is an example of managing the creation of a maintenance schedule for three field devices for securing a living environment deployed in a building.
And a maintenance schedule management computer 2 and three field devices 3-1, 3-2 and 3-3, and FIG. 1 also shows a transmission line 4 for data transmission.

The supervisory control computer 1 controls the three field devices 3-1, 3-2 and 3-3 and stores predetermined operation data.

Computer 2 for maintenance schedule management
Incorporates the operation data stored in the computer 1 for monitoring and control through the transmission line 4 at a constant cycle and automatically creates a maintenance schedule.

In this case, the data acquired by the supervisory control computer 1 is required to record the time of each operation of the field devices 3-1 to 3-3 and to maintain these field devices together with the time record. Specific data is included.

The term "optimum" as used herein means that the location environment has a strong influence on the operation of the field equipment, and the location environment also changes with time. Since the two evaluation scales of cost reduction are quite different, it means that these two evaluation scales are best satisfied for each layout environment.

In the present embodiment, the maintenance schedule is also automatically created by the maintenance schedule management computer 2 to ensure the above-mentioned optimum on a case-by-case basis, and is used for maintenance.

[0014]

As described above, the present invention collects data by collecting operational status data of field equipment online and automatically creating a maintenance schedule.
There is an effect that an appropriate maintenance schedule can be automatically created because accurate information can be obtained without requiring any manpower for inputting.
