Reference numeral 18 denotes a mobile terminal for the site, 19 denotes a barcode reader, 20 denotes a barcode attached to various devices at the site, operation devices (operation switches), etc. at the site, and 30 denotes a procedure manual (or checklist). Work order, work items,
This is information on work contents for performing cooperative work such as work target equipment, work contents, and progress status of work completion / incomplete. These pieces of information are stored in the computers 14, 15 and the like as a database. Reference numeral 40 denotes a work target site.

Next, the operation will be described. Field workers
Various work support information can be referred to by the mobile terminal 18, and various plant data (on-line plant information, offline plant design books, etc.) and various work support information recorded from the computers 14 and 15 are wirelessly transmitted and referred to. Similarly, information input by the portable terminal 8 is transmitted and displayed on the large display device 1 in the central control room and the display device such as the CRT 13.

FIG. 2 shows a screen display example of a procedure manual. As shown in the figure, the procedure manual 30 includes a number (No.) 31 indicating a work order, a procedure 32, and an operation place (work place) 3.
3. Implementation status 34.

When the operation of the main control room and the on-site operation are congested,
The entire work procedure is displayed on the display devices 11 and 13 of the central control room 10 as shown in the figure, and is also displayed on the site terminal 18 so that the entire work status can be shared.
Here, when the operation is completed in the main control room and each site,
By entering "Operation Complete" in the "Implementation Status" column,
The situation is described in a common work procedure manual.

By sharing the work status progress status of the main control room and the work site in this way, it is possible to confirm whether each work can be performed, for example, to confirm that the site operation up to step 3 has been completed. Thus, it can be determined that the procedure N can be performed in the central control room.

As described above, in the first embodiment, the entire work sequence is displayed in the form of a procedure manual (checklist) even if the operation of the device or the confirmation work is congested, and the central processing is performed. Work progress status data input from the control room and the work site are recorded centrally, and these are also provided to the central control room and the work site, enabling efficient and reliable cooperative work and ensuring work. Can be faster.

Embodiment 2 FIG. 3 shows a display screen example of the procedure manual according to the second embodiment. In the second embodiment, as in the first embodiment, the work information of both the central control room and the work site is managed centrally by a computer in the central control room, and further, the operation (work) of the next work step is possible. This is to realize a function for guiding whether or not to perform the operation.

For example, in FIG. 3, since the procedure 3 has not been completed, the procedure N is an example in which a guide saying “work is impossible” is output. Further, a check is performed when an operation target is selected, and an error message 4 is output if the procedure is different. To select the operation target, for example, when the procedure N is pointed by a cursor or the like, the operation in the procedure 3 is not completed, and the error message 35 of “the site work item 3 is not completed” is displayed. Further, the error message signal may be transmitted by voice, or an error message signal may be sent to a required remote location as an external signal.

When the procedure 3 is selected at the site terminal (or the central control room), the item of the procedure 3 is highlighted (or another highlighted display) at both the site terminal and the central control room, and the user is currently working. The work item may be clearly indicated, and the progress of the work may be grasped more. In this way, the selection of procedure N is reduced, and the chance of transmitting a selection error message by procedure N can be reduced. In addition, the selection of the procedure 3 may be input using a barcode described later in the third embodiment. In the first embodiment as well, the above-described reverse display and barcode input can be applied.

As described above, when there is a contextual constraint between the works (for example, when a certain work at the work site is not completed, the next work at the main control room cannot be performed), the work at the work site or the central control room is performed. The computer determines whether or not the work can be performed based on the progress, and provides support information regarding whether or not the next work can be performed.

As described above, the second embodiment can prevent a human error due to a sequence of operations in the central control room and each site.

Embodiment 3 FIG. 4 shows a display example of the procedure manual according to the fourth embodiment, which is an example of a format different from that of the procedure manual according to the first and second embodiments. In this embodiment, when performing a work, a barcode is applied for each operation procedure to reliably select a device in accordance with the procedure, and to select an operation target (misselection of an operation device, a valve at a site, etc.). Selection mistake, etc.).

As shown in FIG. 1, the bar code 20 is pasted on various devices or on-site operating devices (operation switches) in advance. And the bar code reader 1 of the portable terminal 18
The input is performed by reading the barcode 20 at 9.
For example, when the bar code of the valve 2V5252V in FIG. 4 is input, the display is inverted. Then, a check is performed by inputting a valve state such as "open" or "closed" and referring to the valve state in the reference state. This makes it possible to more reliably and promptly display and grasp the state of work performed at a remote place, and to input it to a computer reliably and quickly.

The operator may directly input "open" and "close". Further, both open and closed barcodes are prepared, and input can be made by reading open or closed with a barcode reader. It should be noted that, apart from the bar code for identifying the valve, a bar code that allows the opening / closing bar code to appear on a part of the valve when the valve is opened / closed is pasted, and by reading this, input errors can be further reduced.

As described above, according to the third embodiment, the on / off state of many valves is changed or checked in the on-site work, and the identification of on-site equipment is performed as in the case of checking the state of many equipment. For operations that are prone to errors, target devices are checked using barcodes as a means of inputting work progress according to the procedure manual, and data cannot be input without this check. Selection errors can be prevented.

In the above description, the target work is displayed in reverse video, but it may be displayed in flicker or in different colors.

Embodiment 4 FIG. 5 shows an example of a display screen of the procedure manual according to the fifth embodiment. In the present embodiment, at the time of on-site work, such as checking the line-up of valves at the site, the status of the device should be checked, and the data of the original state should be used as reference data in a database for each operation procedure (for each target device). By collating this with the input operation state, confirmation errors at the site are reduced.

In FIG. 5, the inverted valve "2V-5"
If the reference of the device state (valve state) of “252A” is “open” and “closed” is input as the actual valve state, an error message as shown in the figure “The valve state does not match. Is reported and "Yes" or "No" is selected.

As described above, in the fourth embodiment, the actual device status is compared with the reference device status, and a notification is made that the comparison result does not match, so that a more reliable check can be performed. Work can be assured.

Embodiment 5 FIG. FIG. 6 shows a display example of a site photograph according to the fifth embodiment. In FIG. 6, the site mobile terminal has a function of displaying a photo of the site in correspondence with the order of the work procedure manual in order to visually recognize an operation target at an early stage and to improve work efficiency at the time of site work. Things.

In particular, when it is burdensome to specify on-site equipment to be worked, for example, when checking the status of many on-site manual valves, it is necessary to specify a predetermined one from a number of on-site valves. When it is a burden, the site supporter specifies the work target by presenting a site photograph of the corresponding device in association with the work procedure manual and visually specifying the target.

The information of the work site photo is created in advance as a database, and when performing the work site, the procedure manual to be worked is displayed on the screen. FIG. 5 is a view in which a "site photo" button is displayed by clicking a "site photo" button from a state where a map of a work site (display of a map will be described later) is displayed from the procedure manual.
