Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an equipment management device that manages and maintains plant equipment using a computer and a handy terminal with an IC card.

(Prior art) Generally, unit computers are used to operate and monitor thermal power plants, and the process quantities of each plant equipment are input into the computer through analog input, contact input, pulse input, etc. Close scrutiny or control is being carried out. However, there are process volumes for which it is difficult to input all the signals of each plant equipment into a computer (for example, oil leaks and steam leaks from field equipment), and regular patrols are usually carried out by patrollers. The status of each device is checked and recorded. After the patrol is completed, a report on the patrol results is created, and maintenance slips are created in the event of a breakdown or abnormality in each piece of equipment, but since all of this is done manually, the work time and content created are individualized. There was a difference. In addition, maintenance personnel repair equipment based on maintenance slips, but it takes time to investigate the past repair history of the equipment being repaired, and creating equipment maintenance records is a manual process that requires individual effort. There was a difference.

(Problems to be Solved by the Invention) As described above, according to the conventional technology, each device is checked by patrolling the plant, the patrol report is created, a maintenance slip is created, the repair history of the equipment to be repaired is searched, and equipment maintenance is performed. Everything up to the creation of medical records was done manually, and there were individual differences in the contents of the reports and slips that were created.

In other words, the representation of information was not unified. Moreover, since it was created manually, it took a lot of time.

Therefore, in the present invention, in order to solve the above-mentioned problems, we aim to mechanize the work of patrollers or maintenance personnel, which was performed manually, and to process knowledge and unify collected information, such as reports and slips. The aim is to obtain an equipment management device that eliminates entry errors.

[Structure of the invention] (Means for solving the problem) In order to achieve this objective, the present invention has the following technical means. In other words, an equipment management database for storing various information on each piece of equipment at the site in a computer;
A handy terminal with an IC card that encodes and collects information on each device through patrollers' patrols, a data reading device that reads the data collected by the handy terminal into a computer via the IC card, and a data reader that reads the data. equipment management means for creating patrol reports, maintenance slips, etc. from patrol data and information in the equipment management database, and equipment maintenance charts, etc. from repair information, and a man-machine interface for dialogue with operators. An equipment management device consisting of:

(Function) The bar staff records the status of each equipment at the site using a handy terminal with an IC card, and after completing their patrol, reads the data from the IC card on the handy terminal into a computer, and reports the plant patrol from the computer. maintenance slips are automatically created for equipment that is out of order or out of order. In addition, the operator can easily display the current status and history information of each plant equipment stored in the computer by interacting with the terminal.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention.

In this embodiment, a bar code 1 is attached to each piece of plant equipment for equipment identification. Handy terminal with barcode reader 2 and IC card with keyboard 3
The barcode reader 2 reads the barcode 1 attached to each device. The patrolman determines whether the equipment is normal or abnormal, and inputs a key entry indicating normality or failure on the keyboard of the handy terminal 3. If it is normal, input the operating status. If there is an abnormality, the abnormality code and its contents shown in FIG. 4 will be displayed on the display of the handy terminal 3, and the corresponding abnormality code will be input from the keyboard. In the handy terminal 3, all the operating status and failure status of each device inputted from the keyboard are saved in the IC card.

The collected data is read by a data reading means 11 via an IC card reading device in order to be read into the computer 10, and is stored in the equipment management database 12 as the current patrol data. The equipment management means 13 is also notified of data reading. The equipment management database 12 stores various information on each piece of equipment in the plant. That is, there are two types of device names, one standard, one drawing, nine device conditions, maintenance history, etc.

As shown in FIG. 2, the equipment management means 13 reads the current patrol data from the equipment management database 12 and checks whether there is a failure or abnormality in each equipment. When it is determined that there is a failure or abnormality in this investigation, past failure and maintenance history data is read from the equipment management database 12 to check whether the same failure or abnormality has occurred in the past. If there is the same failure or abnormality, retrieve the maintenance information at that time,
A maintenance slip is created and added as i-original data as failure or abnormality records and maintenance records. If there is no similar failure or abnormality, a maintenance slip is created and the history database is updated.

Furthermore, the terminal 4 is connected through the man-machine interface 14.
As new malfunctioning devices discovered during this patrol, the device name and malfunction details are displayed and the operator is notified. Perform this operation for all devices. We will also create a patrol report based on this patrol data, and
As shown in FIG. 3, maintenance information input through the terminal 4 and the man-machine interface 14 regarding the equipment that has been repaired is saved in the equipment management database 12 as a history, and an equipment diagnosis chart is created.

Next, the operation of this embodiment will be explained. In a plant as shown in FIG. 5, there are valves 100 to 103.

Valve 100 to valve 102 are normal, and valve 103 is leaking water. Patrolmen regularly conduct patrols to check plant equipment. In this patrol, valves 100 to 102 are normal.

Record the normal data on the handy terminal 3.

Also, since the valve 103 is leaking water, a malfunction key input is performed. The error code and details will be displayed on the display of Handy Terminal 3 as shown in Figure 4.

Record the water leak code w001 on the handy terminal 3. The code indicating each valve is read by the barcode reader 2 attached to the handy terminal 3.

After completing the patrol as described above, the IC card containing the information collected by the patrol is taken out from the handy terminal 3, set in the IC card reader 5, and read into the computer 10. As a result, valves 100 to 103
patrol information is read into the computer IO. The read data is processed by the equipment management means 13, and a plant patrol report and a maintenance slip for the valve 103 are output. Furthermore, failure information is displayed on the terminal 4 as shown in FIG.

A maintenance person repairs the valve 103 using this maintenance slip.

When the repair is completed, the maintenance worker inputs maintenance information regarding the current water leak from the valve 103 from the terminal 4 to the computer 10. The maintenance information input by the maintenance personnel is stored in the equipment management database 12 as a history of the valve 103.

Further, if the valve 103 has leaked water in the past, it is output as a maintenance history when creating a maintenance slip, so the maintenance person repairs the valve 103 as shown in the maintenance history or by referring to it.

As described above, in the present invention, the status of the equipment is encoded and input to the handy terminal 3, but the status of the equipment varies widely, and not all of the statuses can be encoded. Also, when referring to the equipment's maintenance history etc. later, it is difficult to understand using symbols alone, so when inputting the equipment status using symbols on Handy Terminal 3, it is also possible to input comments to supplement the status. . Although patrol data is stored in the equipment management database 12, data storage areas for several times are provided for normal equipment data, and all data is not saved. In other words, only the data at the time of failure will be permanently stored in the equipment management database 12. In addition, I is used for data exchange between the handy terminal 3 and the computer 10.
Although a C card is used, it is also possible to directly connect the handy terminal 3 and the computer 10 to exchange data.

Each piece of equipment in the plant is provided with a barcode, and the status of the reading equipment is encoded with a barcode reader and read into a handy terminal, making it possible to unify input data.

After patrolling the plant, if data from the handheld terminal is read into a computer, patrol reports and maintenance slips are automatically created, saving labor and unifying documents.

Furthermore, since the maintenance history of each device is stored in the equipment management database, the maintenance status of each device can be easily checked by displaying this on a terminal device or printer.

〔Effect of the invention〕

According to the present invention, equipment data is read by a handy terminal and documents are automatically created by the equipment management means, so that it is possible to mechanize and save labor.

Furthermore, since the equipment management database stores information on all equipment in the plant, various display formats can be created by processing the information using a man-machine interface.

Therefore, information that is easier for the operator to understand can be provided.
