BACKGROUND OF THE INVENTION
The present invention relates to a facility management system that supports facility inspection work.
[0002]
[Prior art]
In social infrastructure systems such as buildings, plants, water supply, electricity, and communications, the entire system in a facility is now becoming large and complex, and how to maintain and manage the equipment group more efficiently than the initial investment cost. It is important to reduce it. In particular, in the patrol inspection work, the load on the workers is increasing as the number of facilities and inspection items increase. Therefore, a support system that can reduce the burden of maintenance and inspection work is required.
[0003]
As a conventional technique for reducing the burden of maintenance and inspection work, for example, there is one described in Japanese Patent Laid-Open No. 9-34946. In this technique, a plurality of inspection locations, inspection items at each inspection location, inspection history, and the like are stored in advance in a portable terminal computer carried by an inspector. At the start of inspection, if the inspector designates, for example, “inspection” from a plurality of items on the menu screen of the mobile terminal computer, a plurality of inspection locations are displayed on the mobile terminal computer. When the inspector arrives at a target inspection place and designates one of a plurality of “inspection places” displayed on the portable terminal computer, the inspection items and the like of the place are displayed. As described above, this technology supports the inspector by downloading information necessary for the inspector in a pull type and sequentially providing the information.
[0004]
In addition, in “Plant Monitoring and Control Method and Device” of Japanese Patent Publication No. 7-43609, what is a small display device in which a large display device is arranged behind a plurality of small display devices and partial plant information is displayed? A plant monitoring control method and apparatus for displaying summary information of different plants on a large display device are described.
[0005]
Furthermore, in “3D image processing apparatus and method” disclosed in Japanese Patent Laid-Open No. 7-334703, three cameras are installed at a position overlooking a patrol route for regular safety patrols of a supervisor in a plant, while staying in a control room. A 3D image processing apparatus and method capable of virtually walking through a facility are described.
[0006]
[Problems to be solved by the invention]
However, in the prior art described in Japanese Patent Laid-Open No. 9-34946, necessary information must be downloaded in a pull type, and it is necessary to operate the portable terminal computer in a complicated manner at an inspection site or the like, which is relatively troublesome. In addition, there is a problem that it is necessary to become familiar with the use of the terminal computer.
[0007]
In addition, the techniques described in Japanese Patent Publication No. 7-43609 and Japanese Patent Laid-Open No. 7-334703 both effectively display the measurement value information and image information of the plant for inspection and monitoring. There is a problem that countermeasures in the event of abnormalities or changes in the plant are not fully considered.
[0008]
  Therefore, the present inventionEyesThe objective is to provide a facility management system in which the operation of the portable terminal computer carried by the inspector is simple and the load on the inspector can be reduced.

[0030]
Next, the operation of the facility management system of the present embodiment and the operation accompanying the operation will be described with reference to the flowchart shown in FIG.
[0031]
When the inspector conducts an in-house inspection, the portable terminal computer 10 is held. First, the inspection management unit 116 of the main computer 110 searches the inspection checklist database 111 for the inspection sequence number 1 of the inspection checklist, determines the target equipment 201a to be inspected first, and calculates the position of the target equipment 201a. This is notified to the unit 115 and the drawing management unit 117 (step 1).
[0032]
Subsequently, the GPS data measured by the GPS card 16 of the portable terminal computer 10 held by the inspector is transferred to the position calculation unit 115 of the main computer 110 via the wireless LAN card 17 of the terminal computer 10 and the in-facility LAN 220. Sent. Then, as described above, the position calculation unit 115 determines the position of the inspector with an accuracy of several centimeters, and converts the position coordinates of the inspector into predetermined in-facility coordinates (step 2). The position calculation unit 115 obtains a distance R from the position of the inspector to the target equipment 201a determined in step 1 (step 3), and determines whether the distance R is within a predetermined proximity determination distance δ (step 4). ). If the distance R is not within the proximity determination distance δ, in other words, if the distance R is greater than the proximity determination distance δ, the position calculation unit 115 guides the inspector to the target equipment 201a (step 5). ).
[0033]
In this guiding step (step 5), the drawing management unit 117 extracts the in-facility drawing including the location of the inspector determined in step 2 from the drawing database 112, and as shown in FIG. 7, the extracted in-facility drawing 140a. Above, the position coordinates of the inspector are set, and the guide information 142 and 143 are set to go from the position 141 of the inspector to the target equipment 201a. The data of the in-facility drawing in which the position 141 of the inspector and the guide information 142 and 143 are set is sent to the portable terminal computer 10 via the in-facility LAN 220. When the management unit 14 of the portable terminal computer 10 receives the data of the in-facility drawing, the management unit 14 temporarily stores the data in the memory 13 and then displays the data on the touch panel display 12. In this embodiment, the guidance information includes a guidance arrow 142 indicating a route for guiding an inspector to the target facility 201a and a facility name “pump” 143 of the target facility 201a. The guidance information may be any information as long as the inspector guides the target equipment 201a. For example, the target equipment 201a on the displayed in-facility drawing may be blinked or red. .
[0034]
That is, in this embodiment, for example, when an inspector leaves the management room 100 and starts the terminal computer 10 in an attempt to start the inspection, after the various processes (steps 1 to 4) are executed, the terminal computer 10 As shown in FIG. 7, the in-facility drawing 140a of the area including the position of the inspector, the position 141 of the inspector himself, and the guidance information 142 and 143 to the target equipment 201a are automatically displayed on the touch panel display 12 of FIG. The
[0035]
When the inspector approaches the target facility 201a according to the guidance information 142 and 143 displayed on the touch panel display 12, and the distance R to the target facility 201a is within the proximity determination distance δ, in step 4, the position calculation unit of the main computer 110 115 determines that the distance R to the target equipment 201a is within the proximity determination distance δ. Then, the relevant information of the target equipment 201a is transmitted from the main computer 110 to the terminal computer 10, and this information is displayed on the touch panel display 12 (step 6). Specifically, in this embodiment, when the position calculation unit 115 determines that the distance R to the target equipment 201a is within the proximity determination distance δ (step 4), this is indicated by the inspection management unit 116, the facility database management unit. 118 and the drawing management unit 117. The inspection management unit 116 extracts inspection items related to the target facility 201a from the inspection checklist database 111, and transmits this to the terminal computer 10 as related information of the target facility 201a. Further, the facility database management unit 118 obtains the facility information measured by the sensor 202a regarding the inspection item of the target facility 201a, specifically, the “internal temperature of the pump” and the “discharge pressure of the pump” from the facility information database 113 in time series. This is extracted and transmitted to the terminal computer 10 as related information of the target facility 201a. In addition, the drawing management unit 117 extracts in-facility drawings around the target equipment 201a from the drawing database 112, and transmits this to the terminal computer 10 as related information of the target equipment 201a. As shown in FIG. 8, the touch panel display 12 of the terminal computer 10 has an inspection item 133b as related information of the target equipment 201a, time series measured value trend graphs 150b and 150b as facility information, and a drawing around the target equipment 201a. 140b is displayed. As the facility information of the target equipment 201a, there are various meter side values that cannot be displayed at one time. A control bar 161b is displayed next to the time series measured value trend graphs 150b and 150b that are currently displayed. By operating this control bar 161b with the pen 15, a time series meter side value trend graph relating to other meter side values that have not been displayed is displayed. The same applies to the case where there are a large number of inspection items as the inspection items of the target equipment 201a and they cannot be displayed at one time.
[0036]
Next, the inspection management unit 116 of the main computer 101 waits for an input as to whether or not inspection has been performed on the inspection items (step 7), and determines whether or not inspection has been performed on all inspection items regarding the target equipment 201a. (Step 8). The inspection execution input is performed by the inspector checking the inspection items displayed on the touch panel display 12 with the pen 15. At this stage, when it is desired to refer to an inspection checklist of other equipment, drawings around other equipment, image information of each equipment including the target equipment 201a, full screen, and next screen, as shown in FIG. In addition, the corresponding item on the job bar 160 displayed on the touch panel display 12 may be selected with the pen 15. Also, in the operator guidance process of step 5, as shown in FIG. 7, if a predetermined item on the job bar 160a displayed on the touch panel display 12 is selected with the pen 15, desired information can be obtained.
[0037]
If it is determined in step 8 that inspection has not been performed for all inspection items related to the target facility 201a, the inspection is performed for all inspection items, and when inspection is performed for all inspection items, The inspection management unit 116 refers to the inspection checklist in the inspection checklist database 111 and determines whether the inspection has been completed for the last facility (step 9). If the inspection for the last equipment has been completed, the touch panel display 12 returns to the menu screen and the like, and the series of processing is completed. If not, the inspection management unit 116 checks the inspection checklist in the inspection checklist database 111. The target equipment 201b to be inspected next is determined, and the target equipment 201b is notified to the drawing management unit 117 (step 10).
[0038]
When the target equipment 201b to be inspected next is determined, the guidance to the target equipment 201b (steps 2 to 5) is performed as described above, and when the inspector approaches the target equipment 201b, the relation of the target equipment 201b is determined. Information is output (step 6), waiting until inspections for all inspection items of the target equipment 201b are executed (steps 7 and 8), and until it is determined that the target equipment 201b is the last equipment (step 6). 9) The above processing is repeated.
[0039]
On the three large screens 120a, 120b, 120c of the display device 120 in the management room 100, as shown in FIG. 3, for example, an in-facility drawing image 140c around the target equipment 201a, a television camera of the target equipment 201a An image 170c and various measurement value trend graphs 150c of the target equipment 201a can be displayed. An inspection checklist can also be displayed. The display contents of these three large screens 120a, 120b, and 120c are changed by operating the display contents instruction key 186 provided on the operation chair 180.
[0040]
Image information obtained by the plurality of television cameras 210 a and 210 b is temporarily stored in the facility image database 114 of the main computer 110. This image information is subjected to image processing by the facility database management unit 118 so that the operator feels as if the operator is around the equipment, that is, a three-dimensional virtual space is obtained. Such image processing is described in, for example, “3D image processing apparatus and method” of Japanese Patent Application Laid-Open No. 7-334703. The operator operates the position pointing device 181 provided in the operation chair 180, thereby changing the viewpoint of the image and virtually walking through the three-dimensional virtual facility space. For this reason, even if it does not actually go around equipment and inspect, it can go around equipment virtually and inspect.
[0041]
Specifically, when the inspection is performed by the operation in the management room 100, first, the display content instruction key 186 provided on the operation chair 180 is operated, and one of the three large screens 120a, 120b, and 120c is operated. Display an inspection checklist. Next, when the cursor is moved by operating the movement keys 185a and 185b and the target equipment in the displayed inspection checklist is selected, the equipment image is displayed on a screen different from the screen on which the inspection checklist is displayed. . Then, the viewpoint is virtually moved by operating the position pointing device 181 to a position where each inspection item in the displayed inspection checklist can be inspected, and each inspection item is inspected. If there is an abnormality in the measurement value of a certain inspection item, as shown in FIG. 3, the equipment image 170c having the abnormality in the measurement value is displayed on one screen 120b, and time series measurement is performed on another screen 120c. A value trend graph 150c is displayed. Then, by operating the movement keys 185a and 185b to move the time scale 151c drawn on the trend graph 150c in the past direction, the equipment image 170c also goes in the past in synchronization with this. Therefore, the abnormality occurrence time, the equipment state at the abnormality occurrence time, and the equipment state before the abnormality occurrence time can be easily grasped, which can be used as a clue for investigating the cause of the abnormality.
[0042]
The display contents of the display device 120 in the management room 100 and the touch panel display 12 of the portable terminal computer 10 can be the same. For this reason, an inspector who is actually inspecting around the equipment can view the contents displayed on the display device 120 in the management room 100 with the portable terminal computer 10. The operator can view the contents displayed on the portable terminal computer 10 on the display device 120 in the management room 100. In addition, since the management room 100 is provided with the wireless LAN base unit 215 as in the facility 200, the display device 120 in the management room 100 is operated by an inspector operating the portable terminal computer 10. The display content of can be changed.
[0043]
As described above, in the present embodiment, since an inspection checklist is presented in addition to guiding an inspector to the target facility, even if the facility is inspected for the first time, it can be efficiently inspected. In addition, even if there is no download request from the inspector, when the target equipment is approached, related information on the target equipment is automatically presented using this as a trigger. The operation is only to check the inspection items, so that the inspector is free from complicated operations and does not need to learn the operation.
[0044]
Further, in this embodiment, since the operator can follow the trend of the measurement value at hand, even when an abnormality in the measurement value is found during the inspection, for example, without having to bother to contact the management room 100 or the like, It is possible to confirm when an abnormality has occurred and to respond quickly to the abnormality. In addition, since the operator can follow the trend of measured values at hand, there is no need to install a display device for each facility, and the existing facility management system can be expanded as it is. Cost can be reduced.
[0045]
In the present embodiment, when the time series meter side value trend graph 150c is displayed together with the equipment image 170c, and the time scale 151c drawn on the trend graph 150c is moved in the past direction, the equipment image 170c is also displayed. Synchronously with this, it is possible to easily grasp the time of occurrence of an abnormality, the state of equipment at the time of occurrence of the abnormality, and the state of equipment before the time of occurrence of the abnormality, which can be used as a clue to investigate the cause of the abnormality. it can.
[0046]
Furthermore, in the present embodiment, the space inside the three-dimensional virtual facility can be virtually walked through while staying in the management room 100, so that it is virtually impossible to perform inspection around the facility. Inspections can be conducted around the equipment. Therefore, for example, when it is necessary to perform inspections every hour, the inspections that are actually performed around the equipment are performed every three hours, and the remaining inspections are virtual inspections in the state of being in the control room 100. It can be completed and the number of inspection personnel can be reduced, or the burden on the inspection personnel can be reduced.
[0047]
In the present embodiment, the GPS card 16 and the management unit 14 of the mobile terminal computer 10 and the position calculation unit 115 of the main computer 10 constitute a position detection unit. If it is not necessary, the position detection means may be configured by only the GPS card 16 and the management unit 14 of the portable terminal computer 10. In the present embodiment, each database 111, 112, 113, 114 of the main computer 100 constitutes storage means, and each management unit 116, 117, 118 of the main computer also constitutes information management means. For example, a RAM card or the like may be attached to the portable terminal computer 10 and the information management means may be configured by the management unit 14 of the portable terminal computer 10. In this case, since a large amount of data cannot be stored in the RAM card or the like, only necessary data is registered from the main computer 110 before the cyclic inspection. That is, in this embodiment, the facility management system is configured including the mobile terminal computer 10 and the main computer 110, but the facility management system for achieving the first object is configured only by the mobile terminal computer 10. can do.
[0048]
【The invention's effect】
According to the present invention, when the inspector reaches the vicinity of any equipment in the facility, the information related to the equipment is automatically displayed on the mobile terminal, so the operation of the mobile terminal becomes extremely simple, The load on the inspector can be reduced.
[0049]
According to another invention, when the time series measurement value is displayed together with the facility image, and the time scale drawn on the time series measurement value is moved in the past direction, the facility image is also synchronized with this. Therefore, it is possible to easily grasp the abnormality occurrence time, the state of the equipment at the abnormality occurrence time, and the state of the equipment before the abnormality occurrence time, which can be used as a clue for investigating the cause of the abnormality.
