Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an equipment information management device for managing inspection information at various parts of plant equipment.

(Conventional Technique I!) For example, in a thermal power plant, a unit computer is used for its operation and monitoring, and each process state quantity in each part of the plant equipment is expressed using analog signals, contact signals, pulse signals, etc. It is converted into an electrical signal and taken into the unit computer.

On the other hand, in thermal power plant equipment, there are process state quantities necessary for equipment management that are not incorporated into unit computers. For example, oil leaks or steam leaks from field equipment.

Therefore, monitoring of such process state quantities is performed by workers visiting and inspecting plant equipment.

The results were then managed by recording them in the inspection report. Additionally, periodic inspections of plant equipment are conducted for this purpose.

(Problems to be Solved by the Invention) However, since such conventional inspection work is mainly performed manually, the work time is extremely long.

Furthermore, in order to prevent inspections from being overlooked, an inspection route is established for plant equipment, but workers must remember the inspection route without fail. Normally, inspection 1@ route is written on the inspection form and brought in for inspection, but this still places a heavy burden on the workers. In addition, since it is not possible to know at the time of inspection the reference value for determining whether the plant state quantity of the inspection item is normal or the value obtained at the previous inspection, it is difficult to know whether it is normal or not and whether the abnormality has been recovered. There has also been the inconvenience that it is difficult to make appropriate judgments, such as whether or not the application is acceptable.

Furthermore, since the inspection results are stored in the form of an inspection report, there is an inconvenience that a large amount of space is required to store them.

SUMMARY OF THE INVENTION An object of the present invention is to provide an equipment information management device that eliminates the disadvantages of the prior art and allows smooth inspection of plant equipment.

FIG. 1 shows a block diagram of an equipment information management device according to an embodiment of the present invention.

This equipment information management device includes a processing device 1 for managing equipment, a portable terminal device 112 that is carried along the inspection route and inputs inspection state quantities and abnormal state data for inspection items, and a processing device W1. It consists of a connecting device 3 for connecting with a portable terminal device [2], and an interaction device 4 for displaying and outputting inspection result reports, etc., and is also equipped with a printer 5.

FIG. 2 is an external view of the equipment information management device, and the portable terminal device I3 has various function keys,
Further, keys for inputting numerical values are provided as an input device i127, and a liquid crystal display device for displaying necessary information is provided as a display device 1126.

Next, the equipment management processing means 15 of the processing device 1 performs the data transfer processing with the portable terminal device if2 by the data transmission means l6.
and the data receiving means 17, and also performs dialogue control processing with the dialogue device 4 and the printer 5 through the dialogue control means 14, and also issues commands to the database means 11 and performs the input/output processing described above. and writes and reads data necessary for performing dialogue control processing.

The database means 11 of the processing device [1 is composed of, for example, a magnetic disk device, an optical disk device, etc., and this database means 11 stores inspection items corresponding to a plurality of predetermined inspection return routes and inspection state quantities for the inspection items. Limit values are stored in advance. And a portable terminal! 2 through the data receiving means 17, the values of each inspection state quantity for each inspection item of the plant equipment are stored in units of inspection work. In other words, the database means 11 stores various information regarding each inspection item of plant equipment, and when an operator confirms or records and outputs inspection data, he/she can use the dialog device! ! 4, necessary information is displayed and output, and can be recorded and output to a printer 13.

The data transmitting means 16 and the data receiving means 17 are connected to a connecting device IE3 via a cable 18, and this connecting device 3 is detachably connected to the connecting portion 24 of the portable terminal device 2. As a result, the processing device N1 and the portable terminal device 2 are connected and disconnected.

Next, the control means 21 of the portable terminal device 1i2 controls the operation within this portable terminal device 2.

The clock circuit 22 provides current time information to the control means 21,
Input device! The input time data of the inspection state quantity input from 27 is stored in the data memory 23 together with the inspection state quantity. In addition to these inspection state quantities and input time data, the data memory 23 stores various information as described later.

The connecting portion 24 is for connecting to the connecting device W3 of the processing device lit, and is for connecting the portable terminal device 2 to the processing device W1 at the start and end of an inspection. The transmission means 25 is for exchanging data with the processing device 1 while the portable terminal device 2 is connected to the processing device 1.

The display device 26 includes a liquid crystal display device for displaying various message information, a buzzer for generating an alarm sound, etc., and the input device W27 is for inputting the input information of the various keys described above. belongs to.

With the above configuration, when inspection work starts, inspection preparations are performed according to the process shown in FIG. 4.

That is, with the portable terminal device 2 attached to the connection device 3, the worker inputs a command to prepare for inspection through the interaction device M4. This command is input to the equipment management processing means 15 via the dialogue control means 14, and the equipment management processing means 15 displays a guidance screen for inputting inspection items on the dialogue device 4 (
Process 101) guides the worker through necessary information to be input. For example, display a guidance screen like the one shown in Figure 5(a), and enter information such as selecting an inspection route (patrol course), the current load on the thermal power plant, and the identification information of the person in charge of the work. I will guide you to do so. The reason why the magnitude of the load of the thermal power plant is input here is that the limit value of the inspection state quantity may differ depending on the magnitude of the load.

When the inspection route, load value, and person-in-charge code are input in this way, the equipment management processing means 15 notifies the data transmission means 16 of the input various data and current time information, and The data transmission to the device [2 is started (process 102).

That is, the data transmitting means 16 retrieves the identification information of the inspection state quantity, its previous value, limit value, etc. at each inspection point corresponding to the inspection route from the database means 11, and transmits the inspection route, load value, person in charge code, etc. and the current time information is transmitted to the portable terminal device 1i2.

Further, this data transmission process is displayed on the dialog device 4 (process 103: see the bottom of the screen in FIG. 5(a)), so that the worker can use the portable terminal! The status of data transmission to 2 can be appropriately known.

On the other hand, in the portable terminal device [2, when information necessary for inspection work is transmitted from the processing device ill in this way,
The information is temporarily stored in the data memory 23 via the transmission means 25 and the control means 21, and the clock circuit 22 is started by setting specified current time information.

In addition, the clock N22 outputs the current time every moment.

Then, the control means 21 of the portable terminal device II2 performs the processing shown in FIG. That is, for each inspection item, the process state quantity is inputted by the worker.

First, the inspection items at the first inspection point that has not yet been passed on the inspection route are displayed on the liquid crystal display (process 20
1) Check whether the previous value of the process state quantity for that inspection item indicates an abnormal state (judgment 202), and if the previous value indicates an abnormal state, generate an alarm sound to call attention during the current inspection. (process 203).

At this time, when the worker inputs a command to display the previous value or limit value, the previous value or limit value is displayed on the liquid crystal display (Judgment 2o4, 205, Process 2
06, 207), this allows you to know the previous values and limit values of inspection items, allowing you to make appropriate decisions. When inputting the current value for that inspection item, check whether the process state quantity for that inspection item is input as a numerical value or as a state (
Judgment 208), in the case of numerical input, displays numerical input guidance to have the worker input numerical data, stores the input data as the current value of the corresponding inspection item (process 209), and Time information to clock circuit 2
2 and stored in association with the current value (process 210
).

If the current value is outside the limit value (result of judgment 211 is YES), an alarm sound indicating this is generated (
Processing 212).

Additionally, if the process quantity of an inspection item is a status input, status input guidance is displayed to have the worker input information representing the status of the inspection item, and the input data is stored as the current value of the corresponding inspection item. Together (processing 213)
．． Time information at that time is obtained from the clock circuit 22 and stored in association with the current value (process 210).

If the current value indicates an abnormal input (Judgment 21
5), the contents of the abnormality are displayed in a list and one of them is input (processing 216). A list of abnormality degrees is displayed and one is input (process 217). For example, abnormalities include "odor,""foam," and "lubrication."
, "discoloration," etc., and the degree of abnormality includes "immediate treatment,""post-inspectiontreatment," and "wait until next time."

Such data input for one inspection item is repeated for all items (NO loop of judgment N218).

For example, when inspecting the condition of turbine bearing oil, the seventh
As shown in Figure (a), the inspection item "Turbine bearing oil condition?" is displayed on the liquid crystal display device, and the user is prompted to select one of the two conditions displayed.

As a result, when an abnormal state is selected and input, the two screens shown in FIG.

When the input of the details of the abnormality is completed, the screen shown in FIG. 3(d) is displayed and the degree of the abnormality is input.

When data input for one inspection item is completed in this way, the same process is repeated for the next inspection item on the selected inspection route.

In this way, after completing data input for all inspection items on the inspection route according to the inspection items displayed on the liquid crystal display device, the worker attaches the portable terminal device 2 to the connection device 3 and connects it to the interactive device! I! 4 instructs to read the inspection data.

As a result, the equipment management processing means 15 of the processing device 1 first instructs the data receiving means 17 to start receiving inspection data from the portable terminal device 2 (process 301 ).

As a result, the data receiving means 17 receives the portable terminal device I.
2 to start receiving data, and thereby the control means 2
1 transmits the current value of the inspection state quantity stored in the data memory 23 to the processing device 1 via the transmission means 25. Further, the data receiving means 17 stores the input inspection state quantity in the database means 11 in a predetermined format.

At this time, the dialog device 4 displays the status of data transfer from the portable terminal device 2 to the processing device 111, as shown in FIG. 5(b) (process 302).

Then, when the data transfer is completed, the equipment management processing means 1
5 retrieves the inspection data from the database means 11 (process 303), compares the process state quantity with the specified value for each inspection item, and creates information to display that fact when it is in an abnormal state ( Judgment 304, processing 305
), and in other cases, creates information for displaying the inspection results (process 306), thereby displaying the inspection results as a list on the dialog device 4, as shown in FIG.

In this display, the date of inspection result display is set to 11
The inspection date is displayed in R2, the identification information of the inspection route in llR3, the code of the person in charge of work in llR4, the name of the person in charge of work in aR5, and the load value in llR6. In the majority of the lower area, inspection results are displayed in a list according to the inspection route.

Further, when the worker inputs a command to record and output an inspection report through the dialogue device 4, the equipment management processing means 15 retrieves the inspection data of the previous, previous, and current inspections stored in the database means 11. , dialogue control means 1
Output to 4.

As a result, the interaction control means 14 creates inspection report display data in a predetermined format and outputs it to the printer 5.
As a result, the printer 5 records and outputs an inspection report as shown in FIG. 10, for example.

Similarly, based on the inspection data stored in the database means 11, an aging deterioration management table for various equipment as shown in FIG. 11 is recorded and outputted by the printer 5.

In addition, in the same way, an inspection report showing the inspection results for a specified period can be recorded and output.

As explained above, in this embodiment, the portable terminal device 2
The name, limit value, previous value, etc. of the equipment located on the inspection route are stored, and inspection work can be performed by moving and inputting data according to the display contents of the display device 26. The burden on workers is significantly reduced.

Furthermore, since the input data is stored in the database means 11, the space for storing inspection data is significantly reduced. Furthermore, since various reports can be easily created based on the stored contents, usability is greatly improved.

FIG. 12 shows an equipment information management device according to another embodiment of the present invention.

In this embodiment, the unit computers UCI to UCn that perform operation/monitoring control of each plant are connected online to the processing device 1, and the process state quantities required for equipment management are directly input from the unit computers UCI to UCn. There is.

Therefore, in this embodiment, the distance traveled by the worker during inspection can be shortened. Further, since the process state quantities of the entire plant can be appropriately input/managed, comprehensive equipment information management can be performed.

[Effects of the Invention] As explained above, according to the present invention, since inspection data is collected using a portable terminal device, the workload of workers in plant inspection work is significantly reduced, and can reduce the burden of Furthermore, since a database is constructed based on the inspection data and managed collectively, various management reports can be created easily and in an effective format.
