2. Description of the Related Art Conventionally, as part of a plant monitoring operation, during a test operation of a plant, daily inspection operation, and regular maintenance, an inspection operator patrols and inspects each facility at a site, and performs necessary inspection operations. are doing. Inspection operators perform various on-site operations such as periodic opening and closing operations to prevent sticking of valves, checking of meters and other instruments, utility management such as adding lubricating oil, and switching between operation and standby of multiple series of equipment. The inspection operation work has been carried out.

[0003] Since there is no appropriate management means except for equipment that can be monitored and operated from the central operation room by a transmitter or an operating device, such inspection equipment is actually managed by an inspection operator. Must go to the site, perform the necessary inspections, report and record the results. In many plants, computers are responsible for most of the operation management work, and staff supervise the computers indirectly by monitoring the computers, while field work is performed by inspection operators. I had to rely on it.

[0004] In this specification, inspection refers to one of the on-site devices.
The operation refers to looking around one by one, and the operation refers to changing the state of the device. If the equipment is not in the correct condition as a result of the inspection, perform the operation.

Conventionally, a checklist describing inspection operation items and contents has been created, and each item is checked at the time of inspection operation.
By checking each time, the omission of inspection operation was eliminated.

[0006] However, in the checking operation using a paper medium, a handwriting check operation at the site is required, it takes time to check, and an error due to a human error at the time of checking or when writing the check result in a record book. It was easy to cause.

[0007] Further, since it is complicated to perform on-site work using a checklist, a case in which an inspection operator and a checklist administrator form a group to perform a patrol inspection operation, an oversight of an inspection operation work, In order to prevent intentional omission of check due to operator's laziness, multiple checks may be performed by a plurality of persons.

In order to solve such a problem, a portable terminal has been created in which a checklist of inspection operations and procedure items is digitized. At the site, the inspection operator performs the inspection operation while carrying the portable terminal device. Then, the inspection operator performs an inspection operation while looking at the checklist on the display of the mobile terminal device, and inputs the inspection operation result to the mobile terminal every time the inspection operation of the equipment is completed. When all the inspection operations are completed, the mobile terminal device is connected to, for example, a personal computer or the like, and the inspection operation data is transferred, and the inspection operation results are recorded.

In addition, a tag capable of identifying device-specific information is attached in advance to a field device or a facility including the device as a component, and an inspection operator identifies the device from the tag, whereby the device can be identified. In some cases, necessary inspection operation items, contents, and checklists are displayed on a terminal to perform work.

[0010] This kind of prior art is disclosed in Japanese Patent Laid-Open No. 5-1351 / 1993.

And the like.

[0012]

However, in the prior art, a contact-type identification such as a barcode or a non-contact type identification such as a wireless tag can be applied to a target device during an inspection operation at a site. Even if the tag is affixed, since an appropriate site guidance method has not been proposed, it is difficult for the inspection operator to reach the installation location of the device unless the inspection operator is familiar with the site.

[0013] In order to solve such a problem, an object of the present invention is to provide a site inspection operation support device and a site inspection operation method for guiding an inspection operator to a target device.

[0014]

In order to achieve the above object of the present invention, the present invention provides a display device for displaying equipment inspection operation sequence information, site map information, equipment position information, and travel route information.

The receiving device 106 receives the device ID, which is the individual identification information transmitted from the wireless tag 108 placed on the field device 109. An individual identification device of the formula can also be used. The interface device 104 transfers data read by the receiver to the control device 101.

FIG. 2 shows the overall configuration of the on-site inspection operation support device provided with a monitoring device.

The on-site inspection operation support device is a portable terminal device 10.
0 and the monitoring device 400, and the monitoring device 400
It comprises a control device 401, a display device 402, an input device 403, a communication device 404, a storage device 405, and a timer device 406. The control device 401 controls each unit of the monitoring device 400, and includes a CPU, a ROM, a RAM, and the like. The display device 402 is used for displaying a result of communication between the monitoring device 400 and the portable terminal device 100, for traveling maintenance, for displaying information on a site inspection operation, and the like. The input device 403 is used to input necessary data for operation of the on-site inspection operation support system such as patrol maintenance, equipment position, on-site inspection operation content, and the like.

The storage device 405 stores various information such as tour maintenance, equipment position, and site inspection operation contents, and is added, taken out, or rewritten as necessary. These pieces of information may be manually input from the input device 403 such as a keyboard, or may be transferred from another data management system such as a separately provided central control device or business management device via a network or the like.

The monitoring device 400 and the portable terminal device 100 are connected by wire or wirelessly, and the information necessary for the inspection operator to work on the site is collectively before going out to the site inspection operation or during the patrol of the site. Only necessary information is sequentially transferred from the monitoring device 400 to the mobile terminal device 100 by communication. In addition, the result of the inspection operator performing the on-site inspection operation is recorded on the portable terminal device 100, and after the on-site patrol is completed, the result is batch-transferred to the monitoring device 400 or transmitted as appropriate online through communication.

Next, the portable terminal device 100 of the present embodiment
The inspection operation according to the first embodiment will be described with reference to FIGS.

The inspection operator performs the on-site inspection operation according to the inspection operation schedule table 500 shown in FIG. The schedule table 500 describes the inspection operation area, the names of the devices arranged therein, the inspection operation contents, and the scheduled inspection operation time. Then, the device information database 501 shown in FIG.
Based on the inspection operation cycle of each item and the previous inspection operation data, it is possible to determine the equipment to be operated today and the contents of the on-site inspection operation.

That is, the data items of each device are sequentially referred to from each item of the device information database 501. For example, from the item number 10001, the device data item 502 is referred to. In the device data item 502, a device name, a reference number indicating the location of operation contents and inspection contents, a cycle of operation or inspection, date and time of previous operation or inspection, and the like are recorded.

Then, the current date and time are set as T, and an operation or an inspection item that satisfies Ta-A> A (1) is searched for. A device having an operation or an inspection item that satisfies the expression (1) is to be visited at the date and time T.

Here, the inspection refers to an information collecting operation of reading an instrument indication value on site and checking the opening and closing of a valve. As a result, an operation performed on site when the indicated value is not appropriate is referred to as an operation.

For example, in the item number 10001, the installation location (x,
y, z), the content of the inspection operation of the device A is 1000
There are 1-0001 to 10001-mmmm, and the inspection operation contents are 10001-1001 to 10001-n
nnn is indicated and can be operated or checked respectively.

Next, referring to the map, the position and the moving route database 510 shown in FIG. Since there is a non-permissible route 512 or the like in the travel route due to construction or the like, the devices 212 to be inspected and operated from the device layout information 210 (FIG. 3A) and the travel route 511 are taken into consideration. What is necessary is just to determine the optimal inspection operation route to the vehicle. Many methods for determining the optimum route, such as a method using a genetic algorithm, have been proposed, and an appropriate method may be used.

In a power plant or a chemical plant, tens of thousands to hundreds of thousands of devices are arranged, and it is difficult for even a skilled inspection operator to understand the arrangement of all devices in advance. Therefore, the device layout information 210 (FIG. 3A) displayed on the portable terminal device 100 and the inspection operation sequence information 2
00 (FIG. 3 (b)) and the like, the inspection operator goes to the inspection target device, but usually in the plant area,
Since only a minimum number of place name indications, such as indicating where the inspection operator is located, are provided, the inspection operator correctly grasps where he / she is currently and in what direction. It is difficult. The mobile terminal device 100 is useful for solving this problem.

That is, the inspection operator obtains the tag information of an arbitrary device 211 (FIG. 3A) at the site via the communication device 107. The storage device 105 of the portable terminal device 100 holds the location information of the field device from the device information database 501 and the moving route information from the moving route database 510, and the device ID is identified from the wireless tag information.
An installation place is required from now on. Since the inspection operator is in the vicinity of the identified device, the position of the arbitrary device 211 is set as the inspection operator position for convenience, and the next inspection operation route obtained from the inspection operation schedule table 500 and the device information database 501 is used. The optimum route connecting the two device positions is determined from the movement route database 510 and displayed on the display screen 300 of the mobile terminal device 100 shown in FIG. 4, and the inspection operator is notified of the traveling direction 303 of the inspection operation route 201 by the inspection operator. To instruct.

On the display screen 300, a current position 301 of the inspection operator, an arbitrary device 302 designated by the inspection operator, a device 202 to be inspected next, and a traveling direction 303 are shown together with a map.

The method of obtaining the optimum route from the moving route database 510 can be easily realized by a maze method (Japanese Patent Laid-Open No. 7-239873) used for a wiring route search method and the like.

The control of the inspection operation is executed by the control device 101. The method will be described with reference to the flowchart of FIG.

That is, the inspection operator inputs the device ID from the wireless tag 108 of the field device 109. Next, the position where the inspection operator is located is specified based on the device data and the tag ID held in the storage device 105. Subsequently, a target to be moved next by the inspection operator is determined based on the specified inspection operator position and the inspection operation schedule table 500 held in the storage device 105, and the current position of the inspection operator is determined from the travel route information. Calculates the optimal route to move to the moving target, outputs the route along with the map to the display device 102 as the inspection operation route, and ends the operation.

If this inspection operation is repeated as needed during the patrol of the site, the inspection operator can perform the site inspection operation on the optimum route without getting lost.

Next, a second embodiment of the on-site inspection operation support device according to the present invention will be described with reference to FIG.

Equipment 1 in which a site inspection operator is installed at the site

The monitoring device 400 is operated by the communication device 404.
Upon receiving the device ID transmitted from the portable terminal device 100, the control device 401 uses the device information database 501 recorded in the storage device 405 to identify the position of the device with the ID. By outputting this to the display device 402, the current position of the inspection operator can be known. Further, by comparing with the inspection operation schedule table 500 or the like, it can be monitored whether or not the work is progressing normally.

Next, a third embodiment of the on-site inspection operation support device according to the present invention will be described with reference to FIGS. The portable terminal device 100 receives the ID of an arbitrary device 302 from the wireless tag of the field device specified by the inspection operator,
From this, the current position 301 of the inspection operator is specified, and the distance to the target (the inspection target device 202) is obtained. If the distance is long, a map that can be grasped as a whole as shown in FIG. The inspection operation route 201 and the rough direction 303 are shown to the inspection operator.

If the above-described optimum route described with reference to FIG. 4 is determined, the direction can be designated by the forward route.

Next, the inspection operator operates the inspection target device 20.
When the device ID is acquired using an arbitrary device 302 close to 2, the mobile terminal device 100 similarly obtains the positions of the inspection operator and the device 202 to be inspected, and obtains the position of the mobile terminal device 100 shown in FIG. A detailed map is displayed on the display screen 310 and presented to the inspection operator. Thereby, the closer the inspection operator is to the target, the more detailed information can be obtained from the portable terminal device 100, and the inspection operation target device 202
31 for moving to the position where the heating blower is
The inspection operator can smoothly move to the place where the inspection target device 202 is located by the arrow 1 and the arrow 312 instructing to go up. If the above-described optimal route described with reference to FIG. 4 is determined, the direction can be designated in the forward route.

Next, a fourth embodiment of the on-site inspection operation support device according to the present invention will be described. In order to display a map showing the inspection operation route 201 on the mobile terminal device 100,
6 and 7, the inspection operation schedule table 500 that can specify the inspection operation target device, the device information database 501, the movement route database 510, and the movement route 511.
Such information must be stored in the storage device 105 of the mobile terminal device 100 in advance. If the number of field devices is large or the inspection operation area is widened, the amount of data becomes enormous and cannot be stored in the storage device 105, or the control device 101 of the portable terminal device 100 requires time for search and identification. May be considered.

Therefore, a part or all of this information is provided in the monitoring device 400, and the communication between the portable terminal device 100 and the monitoring device 400 specifies the current position of the inspection operator and determines the map to be displayed. By performing the above operation on the monitoring device side, the load on the mobile terminal can be reduced.

Next, a fifth embodiment of the on-site inspection operation support device according to the present invention will be described. Monitoring device 4 shown in FIG.
