BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal device for supporting inspection and maintenance of equipment, and an inspection and maintenance method using the same.

[0002]

2. Description of the Related Art Conventionally, as part of a monitoring operation of a plant, a worker sometimes goes to a site and looks around each facility at the time of initial start-up of the plant or during regular maintenance. The worker checks the condition of the equipment by checking instruments such as a meter or with his own eyes, and performs adjustment work such as turning a valve to a designated position.

[0003] Among such facilities, there are some facilities in which the installation location is difficult to understand and those having similar shapes. Therefore, a mechanism is required to check whether the inspection work has been performed on the target equipment.

Conventionally, items to be inspected are written out and each item is checked one by one during inspection work.
The inspection was overlooked. In addition, where necessary, the location and characteristics of the equipment to be inspected were added as precautionary notes, and efforts were made to eliminate confusion between inspection targets.

[0005] However, work on paper is time-consuming to check, and it is easy to make mistakes when checking or when writing the check results in a record book.

Further, in order to prevent a worker to be overlooked from overlooking or intentional omission due to negligence, a mechanism such as multiple checks by a plurality of persons may be adopted.

[0007] In view of such circumstances, a portable terminal has been created in which a checklist of inspection items is digitized.

[0008] At the site, a worker carries out the inspection while carrying the portable terminal. Then, the worker performs the inspection while looking at the checklist on the display of the mobile terminal, and inputs the inspection result to the mobile terminal every time the inspection work of the equipment is completed. When all checks have been completed, the mobile device
Inspection data is transferred by being connected to a personal computer or the like, and the inspection result is recorded.

This type of prior art is disclosed in, for example,
No. 135186, JP-A-6-12588, JP-A-7-262225, JP-A-6-11365 and the like.

[0010]

However, in the prior art, although the checklist of the check items is digitized, if the user has no way of knowing how far the check has progressed, the equipment to start the check will be started. However, it may cause workers to worry that the equipment is a real purpose equipment.

Further, even if the target equipment is inspected, the state of the equipment is checked manually, and there is a possibility that an overlook or intentional omission of the check may occur.

In view of such a problem, an object of the present invention is to
Provided is a mobile terminal device for inspection and maintenance support that can reliably perform inspection and maintenance of equipment.

The contents of the inspection schedule in the storage device 105 are displayed on the display 103 by inputting a predetermined command from the input device 104 or when the control device 102 determines that it is necessary.

Next, the operation of the portable terminal device of the present embodiment will be described along with the inspection work actually performed in the plant.

First, an example of the inspection schedule is shown in FIG.
(A). For items on the inspection schedule, see 3
01 is the inspection order, 302 is the inspection guidance, 303 is the equipment ID, 304 is the equipment name, 305 is the inspection content, 306
Is the detection timing, 307 is the model result, and 308 is the change destination. Details of each item will be described as needed. The inspection content 305 is linked to another table so that a plurality of types of inspection actions can be specified.
An example of another table is shown in FIG. 501 is
Details of the inspection contents, 502 is the inspection type. 503
Is the inspection result, but is not entered in the figure. The inspection schedules shown in FIGS. 3B and 3C are used in an embodiment described later.

Then, the worker checks the state of the equipment in accordance with the inspection order of the inspection schedule shown in FIG.

The first is the inspection of the instrument 1 registered as the inspection sequence "1". This inspection work will be described according to the flow of FIG.

Step (S) 201: The worker having the portable terminal to which the inspection schedule shown in FIG.
Go to the site and search for the target equipment according to the inspection guidance displayed on the terminal display. An example of the inspection guidance displayed on the display of the terminal is shown in FIG. In this way, the terminal display shows a map of a specific area of the plant, the location of the equipment to be inspected on the map,
From the current position, a guide arrow for arriving there, and a textual guide of the inspection location and general contents of the inspection are displayed. Among them, the information on the geographical guidance is developed from the “map 1” data of the inspection guidance 302 of the inspection schedule. The general content of the inspection is
It is developed from the equipment name 304 and the inspection content 305.

The worker who finds the control panel according to the inspection guidance displayed on the display opens the door of the control panel. A wireless tag is attached to an instrument 1 (not shown) installed in the control panel. Information indicating the equipment ID “A001” of the meter 1 is recorded in the wireless tag, and the equipment ID is transmitted from the wireless tag.

S202: After opening the door of the control panel, the worker brings the portable terminal close to the wireless tag. As described above, unless the door is opened, it is not possible to receive infrared rays or high frequencies from the wireless tag.

The equipment ID "A00" transmitted from the wireless tag
The interface device 101 that has received 1 ”transfers this to the control device 102.

S203: The control device 102 refers to the inspection schedule to confirm that the received equipment ID is “A001”. Specifically, in the column of the equipment ID 303 of the inspection schedule, the inspection order 30
1 is read out from the row of "1". If the equipment ID read from the inspection schedule matches the equipment ID received from the wireless tag, the process proceeds to S204 because the equipment whose inspection work is to be started is the target equipment. The recognition result indicating that the equipment is the target equipment is stored in the storage device 105.

As described above, in this embodiment, not only can the equipment ID of the equipment to be inspected be automatically taken into the portable terminal, but also the equipment ID cannot be obtained unless the door is opened. Increases the reliability of inspection work.
That is, it is possible to prevent an erroneous operation such as leaving a record of an inspection operation even though the door of the control panel is not opened.

S204: The control device 102 displays on the display of the terminal a confirmation display indicating that the inspection target is the target equipment. The confirmation display may be such that the color of the figure representing the control panel is darkened, as shown in FIG.

S205, S206: Next, the worker
Check equipment details. As the inspection contents, the contents of another table in FIG. 5 are developed on the display. The display contents are shown in FIG.
It is as follows. Here, when the inspection type is “check”, a square check box is displayed. When the inspection type is “selection”, a radio button imitation is displayed as a selection candidate. A text area where text can be written is displayed.

When the check box is picked, an X mark is entered. One of the selected radio buttons is displayed as a black dot. When handwriting is input to the text area using a dedicated pen, a character recognition process is executed by the control device 102, and a character as a recognition result is displayed in the text area.

The above input results are recorded in each item of the inspection result 503 in another table of FIG.

S207: The control unit 102 compares the content of the predetermined item of the inspection result 503 with the content of the model result 307 of the inspection schedule. If the content of the predetermined item matches the model result, the process proceeds to S209; otherwise, the process proceeds to S208.

S208: The content of the inspection schedule is rewritten by the control device 102. Here, “3” is registered as the change destination 308 of the row of the inspection order “1”.
When “3” is registered as the change destination 308, the inspection sequence “3” is executed after the inspection sequence “1”, and the inspection sequence “2” is skipped. Note that S207 and S208
Is not an essential step and need not be provided in the case of system specifications that do not change the schedule.

S209: When all the inspection work according to the inspection order is completed, the control device 102 terminates the processing, otherwise returns to S201 and starts the next equipment inspection processing.

When all the inspection work is completed, the worker returns to the monitoring center of the plant and uploads the inspection result stored in the portable terminal to the management computer. This inspection result is then used for a maintenance plan such as equipment replacement and creation of a new inspection schedule.

Next, the second embodiment of the portable terminal device according to the present invention will be described.
An embodiment will be described.

Here, an example of a portable terminal that automatically determines the state of the equipment using the acquisition timing of the equipment ID will be described with reference to the inspection schedule in FIG.
The mobile terminal used is exactly the same in hardware as that shown in FIG. The flow of the program used is shown in FIGS. S110 in FIG.

The time information output from the timer device 106 is input to this determination means. The determination means is also realized by the execution of a predetermined program by the CPU, as described above. Figure 3 shows the inspection schedule.
The one shown in (b) will be used, and here, the discussion will be particularly focused on the inspection order “2”.

S1101: The worker finds the inspection target according to the inspection guidance on the display as shown in FIG. It is assumed that the inspection target is the valve 1 (the valve 1005 shown in FIG. 10). In FIG. 10, 1001,
1002 is a wireless tag, 1003 is a steering wheel, 100
Reference numeral 4 denotes a cover fixed in the middle of the handle 1003. The wireless tag 1001 stores information indicating the facility ID “B001”, and the wireless tag 1002 stores information indicating the facility ID “B002”. In addition,
When the handle 1003 is turned to open the valve 1005, the cover 1004 goes up. When the handle 1003 is turned in the opposite direction to close the valve 1005, the cover 1004 goes down. When the cover 1004 moves to the lowest position, the wireless tag 1002 is covered by the cover 1004 and the wireless tag 1
Infrared rays and the like emitted from 002 are blocked by the cover 1004.

S1102: First, the worker brings the portable terminal close to the wireless tag 1001. The interface device 101 that has received the equipment ID “B001” transmitted from the wireless tag 1001 transfers this to the control device 102.

S 1103: The control device 102 refers to the inspection schedule stored in the storage device 105 to confirm that the received equipment ID is “B001”. If the inspection target is the target equipment,
The recognition result indicating that the equipment is the target equipment is stored in the storage device 105.

S1104: Although not shown, a confirmation display similar to that shown in FIG. 6 is displayed on the display.

S1201: The worker who sees the confirmation display on the display subsequently performs a detailed inspection. In FIG.
An example of another table linked to the inspection content 305 of the inspection schedule of FIG. 3B is shown. 901
Indicates the details of inspection, and 902 indicates the type of inspection. 903
Is a check result, but is in an uninput state here.

Inspection details 901 and inspection type 902
Are displayed on the display.
Is open "is displayed. Here, it is assumed that the valve 1005 at the site is in an open state as shown in FIG. 10A, and this state is a correct state.

Then, the operator visually checks the valve 1005.
Is opened, and the input device 104 inputs that the valve 1005 is open.

S1202: When the operator inputs that the valve 1003 is open from the operator,
The process advances to step S1203 to read the identification information.

S1203: The worker enters the wireless tag 1001
Over the mobile terminal to acquire the equipment ID “B001”. This equipment ID is temporarily stored in the control device 102.

S1204: Subsequently, the worker enters the wireless tag 1
Hold the mobile terminal over 002 to acquire the equipment ID “B002”. This equipment ID is also temporarily stored in the control device 102.

S1205: The control device 102 executes S120
After reading the equipment ID in S3, the equipment I in S1204 is stored within the time (here, “1 second”) stored in the detection timing 306 of the inspection order “2” in the inspection schedule.
It is determined whether D reading has been performed. S1 within 1 second
If the facility ID of 204 has been read, S1207
Proceed to. The wireless tags 1001 and 1002 are relatively close as shown in FIG. Therefore, valve 1
If 005 is in the state of FIG. 10A, the worker can use the equipment I of the wireless tags 1001 and 1002 unless the portable terminal is dropped on the floor or the handheld terminal is held up.
D can be continuously captured within one second.

S 1206: The control device 102 refers to the equipment ID 303 of the inspection schedule, and executes S 1203, S 1
It is checked whether the two equipment IDs acquired in 204 are correct. 2 acquired in S1203 and S1204
If the two facility IDs are correct, the process proceeds to S1207.

S1207: The fact that the valve 1005 is open is recorded in the inspection result 903 of another table in FIG.

According to the present embodiment, the valve 10
05 is closed (the valve 1005 is
Even if the worker inadvertently or inadvertently inputs that the valve 1003 is open in S1201 (in spite of the state (b)), the fact is determined in S1205. The information that 1003 is open is not recorded. Specifically, when the valve 1005 is closed, the wireless tag 10
Since the equipment ID cannot be obtained from the device 02, the processing is performed in step S1.
Before proceeding to S206, S1208 is executed.

In S1208, the control unit 102
Asks the worker whether to retry. This step S1208 is executed even when one of the acquired facility IDs is invalid. If the worker instructs a retry in S1208, the process returns to S1203. If no retry is performed, the process advances to step S1209. In S1209, the fact that the valve 1005 is closed is recorded in the inspection result 903 of another table in FIG. In S1203 and the like, when the terminal ID is erroneously read by mistake in the operation of the terminal and after that no retry is designated in S1208, the fact that the valve 1003 is closed is recorded, while the valve 1005 is not There is no evidence that it is actually closed. However, in this case, since the state in which the valve 1005 is open is normal, if an operator later sees a record indicating that the valve 1005 is closed, the occurrence of an abnormal situation can be immediately recognized.

In step S1202, the worker
If the user inputs that the valve 1005 is closed,
Proceeding to 1209, "valve closed" is recorded as it is.

The flow of FIGS. 11 and 12 has been described above. In addition to opening and closing the valve, a wireless tag is attached to each of the right and left doors so that the equipment ID cannot be obtained unless it is opened. It is also possible to detect the state of the door.

Also, in the flow of FIG. 11, S20 of FIG.
7, S208 may be added.

Note that a predetermined encryption key may be transmitted from the wireless tag in addition to the facility ID.
The predetermined encryption key issued together with the equipment ID is collated on the terminal side using the collation key. Of course, the encryption key may not be generated from the verification key using a mechanism such as public key encryption. In this way, even if a forged device or the like that emits a signal indicating the equipment ID is carried into the plant, the credibility of the inspection result is guaranteed.

Next, the third embodiment of the portable terminal device according to the present invention will be described.
An embodiment will be described.
