Summary of the Invention

Problems to be Solved by the Invention

[0004] According to the prior art described above, if the cause of a malfunction can be accurately identified at the initial stage, the relevant manager who receives the notification can go directly to the site and respond to the abnormality promptly. However, in actual maintenance work, identifying the cause of a malfunction is not easy and takes time. Furthermore, even when a manager goes to the site where the equipment suspected of malfunctioning is installed, it is not uncommon for the direct cause of the malfunction to not be in that equipment, but rather in other equipment (for example, parent-child equipment installed in a distant location). Therefore, with the prior art described above, the relevant manager who receives the notification may not be involved with the equipment that caused the malfunction, and the repair manuals they obtain may not be useful. In such situations, it is difficult to carry out maintenance work efficiently.

[0005] Therefore, the present invention aims to provide a technology for efficiently carrying out facility maintenance operations. [Means for solving the problem]

[0006] To solve the above problems, the present invention employs the following maintenance support system. Note that the following statements in parentheses are merely examples, and the present invention is not limited thereto.

[0007] In other words, the maintenance support system of the present invention comprises a central monitoring unit that monitors multiple pieces of equipment installed in a facility and, when a malfunction occurs in any of the pieces of equipment, sends an error notification to a terminal used by the equipment staff; a display processing unit that, in relation to the error notification, displays the location of the malfunctioning equipment and the route from the terminal's current location to the location on a screen that is displayed three-dimensionally on a 3D model of the facility on the terminal; and an information providing unit that provides the terminal with information necessary for repairing the malfunctioning equipment.

[0008] According to this type of maintenance support system, the route from the current location to the location where the malfunction occurred is displayed, allowing maintenance personnel to proceed to the site while viewing the screen display. Furthermore, information necessary for repairing the malfunctioning equipment (e.g., keys needed for movement, tools needed for repair, equipment manual, etc.) is provided, so maintenance personnel can perform work based on the provided information without having to individually search for the necessary information. This improves the efficiency of malfunction response work and reduces the time required for repair.

[0009] Preferably, in the maintenance support system described above, the display processing unit can display on the screen the installation locations of equipment that have a parent-child relationship with the equipment where the malfunction occurred.

[0010] According to this type of maintenance support system, even if the equipment notified as having a malfunction does not actually have a malfunction, it is possible to check the equipment that has a parent-child relationship with that equipment on the spot. This allows for the identification of the true source of the malfunction by searching for related equipment, and enables the acquisition of information necessary for repairing that equipment on-site and the implementation of appropriate measures.

[0011] More preferably, the maintenance support system described above further includes a database that stores historical information regarding the status of equipment installed in a facility, and an update registration unit that receives updates from facility staff regarding the status of malfunctioning equipment and registers them in the database, and the display processing unit displays the location of the malfunctioning equipment in a manner that allows for identification of the equipment's status.

[0012] According to this type of maintenance support system, the location of the malfunctioning equipment is displayed in a way that allows for identification of its current status, making it easy to understand the status of the repairs being made to the malfunctioning equipment. Furthermore, since historical information regarding the equipment's status is stored in a database, the accumulated data can be used to improve the equipment's operating rate.

[0013] More preferably, the above-described maintenance support system further includes a determination unit that determines whether the degree detected by a sensor in a predetermined area of ​​the facility is normal, using a model that has been pre-trained on the degree of each normal state in each area of ​​the facility for a predetermined element detected by a sensor; and a malfunction warning unit that, if the determination unit determines that it is not normal, registers a malfunction warning in the database regarding the possibility of a malfunction occurring in the equipment installed in the predetermined area where the determination was made. Furthermore, when a malfunction warning is registered, the system further includes a warning notification unit that sends a warning notification to a central monitoring unit and a terminal, the central monitoring unit is capable of displaying information regarding the malfunction warning on a screen for central monitoring with respect to the warning notification, the display processing unit is capable of displaying a predetermined area on the screen with respect to the warning notification, the information provision unit is capable of providing the terminal with a checklist consisting of multiple items corresponding to the content of the malfunction warning with respect to the warning notification, and the update registration unit accepts updates regarding malfunction warnings by equipment personnel who have performed inspections according to the checklist and registers them in the database.

[0014] According to this type of maintenance support system, the determination unit determines whether the level of environmental elements in each area of ​​the facility is normal (i.e., whether or not an environmental abnormality has occurred), thereby improving the efficiency of inspection work and reducing the time required. Furthermore, if it is determined that the environment is not normal (an environmental abnormality has occurred), a malfunction warning is registered in the database, and a warning notification is sent to the central monitoring unit and terminals, allowing relevant parties to quickly share information about the occurrence of an environmental abnormality and take appropriate action. In addition, since facility personnel can perform inspections according to the provided checklist, they can perform inspections efficiently without having to individually search for the information necessary to inspect the area corresponding to the warning notification.

[0015] Furthermore, preferably, in the maintenance support system described above, the display processing unit can display information about a predetermined element that has been determined to be abnormal in the predetermined area, along with the display of a predetermined area.

[0016] According to this type of maintenance support system, when a serious environmental anomaly occurs in a designated area, it is possible to know in advance the current state of the environmental elements that caused the malfunction warning, allowing maintenance personnel to take safer and more appropriate actions depending on the situation. For example, if it is considered dangerous for maintenance personnel to go to the site, it becomes possible to share information between the central monitoring system and the maintenance personnel via a database and have the central monitoring system take the most appropriate measures.

[0017] More preferably, the above-described maintenance support system can display information about a predetermined element that has been determined to be abnormal in that predetermined area, along with the display of a predetermined area. Furthermore, it includes multiple types of models that correspond to multiple types of sensors, and a model selection unit that selects a model from among the multiple types of models according to the location of the terminal carried by the maintenance worker patrolling the facility.

[0018] This type of maintenance support system allows for the determination of whether environmental abnormalities have occurred in various environmental elements within a facility, thereby enabling more reliable inspection work. Furthermore, since the available model is automatically selected according to the terminal's location information, maintenance personnel do not need to be aware of which model is available at their current location, allowing them to concentrate on inspection work using their own senses.

[0019] More preferably, in the maintenance support system described above, the sensor is mounted on or connected to a terminal.

[0020] According to this embodiment of the maintenance support system, since the sensor is mounted on or connected to the terminal, environmental information can be collected and it can be determined whether or not an environmental abnormality has occurred even in locations where sensors are not installed or where installation is difficult. [Effects of the Invention]

[0021] According to the present invention, facility maintenance operations can be carried out efficiently.

Modes for Carrying Out the Invention

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a preferred example of the security service support system is given, but the form of the present invention is not limited to the example. Also, in the following description, synonymous words such as facilities, equipment, and devices are collectively referred to as "facilities".

[0024] 〔Operating Environment of the Security Service Support System〕 FIG. 1 is a schematic diagram showing the operating environment of the security service support system 1. The security service support system 1 is a system that supports the security services of a facility, specifically, the response to malfunctions occurring in the facilities installed in the facility (hereinafter abbreviated as "response to facility malfunctions") and the improvement of the efficiency of daily inspection work.

[0025] The maintenance support system 1 operates in an environment where a central monitoring system 100, which monitors various equipment such as air conditioning, lighting, and electricity installed in a facility and centrally manages information related to them, a management server 200 that manages various databases used by the maintenance support system, and applications 300 installed on information terminals MD such as tablets, smartphones, and mobile PCs used by facility personnel in the field are connected to a network 50. Note that the network 50 is not limited to private networks such as LANs and VPNs, but may also include public networks.

[0026] If a malfunction occurs in any of the equipment, an error notification is first sent to the central monitoring system 100. The central monitoring system 100 constantly manages the status of the equipment and can display and check the operating status of each piece of equipment on its screen. Upon receiving an error notification, the central monitoring system 100 sends an error notification to the information terminal MD (more precisely, application 300). In response to the error notification, application 300 communicates with the management server 200 and can display various information on the screen of the information terminal MD, including the location of the malfunctioning equipment, the route to get to that location, and information necessary to repair the malfunction.

[0027] The above is an outline of the processing flow for responding to facility malfunctions in Maintenance Support System 1. In addition to this, Maintenance Support System 1 also has functions to improve the efficiency of daily inspection work.

[0028] [Configuration of the maintenance support system] Figure 2 is a block diagram showing the configuration of Maintenance Support System 1. The network diagram is omitted in Figure 2. The configuration will be explained below in accordance with the flow of information within Maintenance Support System 1.

[0029] The central monitoring system 100 includes, for example, a display unit 110 and an error notification unit 120. The display unit 110 displays the status and operating conditions of the equipment on a screen for central monitoring. The error notification unit 120 receives an error notification when a malfunction occurs in any of the equipment monitored by the central monitoring system 100 and sends the error notification to the application 300. In addition, regarding error notifications, the display unit 110 can display the facility in 3D on the screen and map the location of the malfunction corresponding to the error notification (location of the malfunctioning equipment) and the current location of the equipment operator onto the 3D display.

[0030] The management server 200 includes, for example, a facility management database 210, a BIM database 220, a judgment unit 230, a warning notification unit 240, and the like.

[0031] The facility management database 210 is a database that manages various information related to facility management. For example, it includes a facility information table that stores detailed information about equipment (equipment name, installation location, relevant area, manual, related information, etc.), a response history table that stores history information of responses taken in response to error notifications and warning notifications (status, update date and time, response details, etc.), as well as tables that manage the status of equipment and other tables that store related information.

[0032] The BIM database 220 stores BIM models corresponding to the facility's completion drawings and views that allow the BIM models to be displayed from various perspectives (hereinafter, BIM models and their views are collectively referred to as "BIM data"). The determination unit 230 determines whether the levels of environmental elements (e.g., sound, temperature, etc.) detected by various sensors in each area of ​​the facility correspond to normal conditions, that is, whether or not an environmental abnormality has occurred, using a model (hereinafter referred to as "determination model 232") that has been pre-trained using actual detection data as a training dataset for these environmental elements. The types of determination model 232 and their inputs and outputs will be described in detail later with reference to another drawing. Details of the warning notification unit 240 will also be described later.

[0033] The information terminal MD is equipped with sensors such as a position sensor PS and a microphone MC, which are used by application 300 as needed. The location of the information terminal MD detected by the position sensor PS, i.e., the current location of the facility worker, can be constantly monitored from the central monitoring system 100. In case the facility worker is involved in a secondary disaster while working, the microphone MC and speaker SP are configured to be controllable from the central monitoring system 100.

[0034] Application 300 includes, for example, a display processing unit 310, a position detection unit 320, an information provision unit 330, an update registration unit 340, a judgment window unit 350, a malfunction warning unit 360, and the like.

[0035] When the display processing unit 310 receives an error notification from the central monitoring system 100, it retrieves the facility's BIM data from the BIM database 220, displays the facility in 3D on the screen of the information terminal MD, and maps the location of the malfunction corresponding to the error notification (the location of the malfunctioning equipment) onto the 3D display. The display processing unit 310 also displays the movement path from the current location of the information terminal MD, detected by the position detection unit 320 using the position sensor PS, to the location of the malfunction on the 3D display. Furthermore, the display processing unit 310 can display the locations of equipment that have a parent-child relationship with the malfunctioning equipment, as well as equipment of the same system as the malfunctioning equipment, in a manner that allows for identification.

[0036] The position sensor PS may determine the relative position from a reference point by combining an acceleration sensor, angular velocity sensor, and magnetic sensor mounted on the information terminal MD, or it may determine the current location using other positioning methods (for example, methods using indoor GPS or beacons).

[0037] The information provision unit 330 retrieves information such as keys needed to move to the location of the malfunction, manuals needed to repair the malfunction, and types of tools needed to correspond to the content of the error notification from the facility management database 210 (facility information table) and displays it on the screen in relation to the display made by the display processing unit 310. The update registration unit 340 displays an input form for response reports on the screen of the information terminal MD, accepts input from the facility staff who performed the response, such as the details of the response and the status after the response, and registers it in the facility management database 210 (response history table).

[0038] The judgment window unit 350 refers to the facility management database 210 to identify the area to which the information terminal MD's current location corresponds and the equipment installed around the current location, and selects a judgment model that is available at the current location. Then, the judgment window unit 350 transmits detection information of environmental elements detected by sensors mounted on or connected to the information terminal MD, or sensors installed on site, and information about the current location to the judgment unit 230, which makes a judgment using the judgment model corresponding to the environmental elements, and receives the judgment result. If the judgment unit 230 determines that something is not normal, or if a facility worker determines that something is not normal, the malfunction warning unit 360 registers a malfunction warning in the facility management database 210 indicating that there may be a malfunction in the equipment around the current location.

[0039] When a malfunction warning is registered in the facility management database 210, the warning notification unit 240 sends a warning notification to the central monitoring system 100 and the application 300.

[0040] When the central monitoring system 100 receives a warning notification, the display unit 110 retrieves the facility's BIM data from the BIM database 220 and displays the facility in 3D on the central monitoring screen. The display maps the area where the malfunction warning was issued onto the 3D display and also displays information about the environmental element that caused the malfunction warning (such as the type of environmental element and its detected value).

[0041] On the other hand, when application 300 receives a warning notification, first, the display processing unit 310 displays the facility in 3D on the screen of the information terminal MD based on the BIM data obtained from the BIM database 220, and maps the area where the malfunction warning was issued onto the 3D display. At this time, information regarding the environmental element that caused the malfunction warning (such as the type of environmental element and its detected value) may also be displayed. In addition, the information provision unit 330 obtains a checklist consisting of multiple items corresponding to the content of the malfunction warning from the facility management database 210 (for example, the checklist table) and displays it on the screen. After the facility staff perform an inspection according to the checklist, the update registration unit 340 displays an input form for the inspection report regarding the malfunction warning on the screen, accepts input such as the inspection results and the status after the inspection by the facility staff who performed the inspection according to the checklist, and registers it in the facility management database 210 (correspondence history table).

[0042] In this way, in the maintenance support system 1, the central monitoring system 100, the management server 200, and the application 300 work together to provide various information to maintenance personnel via the application 300 when error notifications or warning notifications are issued. Furthermore, when maintenance personnel go to the site and take action based on the provided information, the status is updated by the maintenance personnel, and the details of the action are registered in the facility management database 210, and historical information regarding the maintenance and management of the equipment is accumulated. This historical information accumulated in the facility management database 210 can be used to improve the MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair) of each piece of equipment, and to analyze trends in malfunctions, etc.

[0043] In the illustrated example, a microphone MC and a temperature sensor TS mounted on the information terminal MD are used as sensors, but the type of sensor (type of environmental element to be detected) is not limited to these. In this embodiment, the types of environmental elements assumed are sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose. Furthermore, for detecting environmental elements, sensors mounted on or connected to the information terminal MD may be used, or information detected by sensors installed on-site may be acquired and used via wireless communication.

[0044] [Screen display by the application] Figure 3 shows an example of the display on the screen of the information terminal MD by application 300. The screen is provided with, for example, a 3D display area 312, a menu button display area 314, and a list display area 316. The size of the 3D display area 312 and the list display area 316 can be enlarged or reduced by the equipment operator as needed.

[0045] In the 3D display area 312, the facility is displayed in 3D based on BIM data, and a mark and management number are displayed at the location of the malfunction. The mark is displayed in a color corresponding to the status so that the current response status can be easily identified. For example, the mark is displayed in red immediately after a malfunction occurs, in yellow when a supervisor has responded, in green when a response process is underway, and in white when it is awaiting approval for completion of the response.

[0046] The menu button display area 314 is equipped with various operation buttons for switching the display content of the 3D display area 312. By selecting the corresponding operation button, the equipment operator can zoom in and out of the display, switch views (display in different views), display the route from the current location to the location of the malfunction, display equipment on the same system, display the parent-child relationships of equipment, and so on.

[0047] The list display area 316 displays information about malfunctions that occurred within a predetermined period, in chronological order. The list display includes information such as the management number (No), the time the malfunction occurred, the ID of the equipment where the malfunction occurred, the area in question, the error ID, the current status, the display method of the mark on the 3D display, the staff ID of the equipment worker in charge, and the equipment worker's telephone number. The content displayed in the list display area 316 can be switched. Equipment workers can, for example, select a designated area in the list to display the input form for the response report, the response report list, or related information such as manuals associated with each piece of equipment.

[0048] For example, if a maintenance worker selects a malfunction location displayed in the 3D display area 312, a malfunction details window pops up, overlapping the 3D display of the equipment, and displays detailed information about the selected malfunction. When the [Display] button for related information displayed in the malfunction details window is selected, the pop-up window closes, and the route from the current location to the selected malfunction location is displayed on the 3D display in an easily identifiable manner. In addition, the list display area 316 displays the keys required to move to the malfunction location, the types of tools required corresponding to the error ID, and the manual for the malfunctioning equipment. Furthermore, as the maintenance worker moves along the displayed route, the maintenance worker's current location information (location of the information terminal MD) is updated accordingly, and the current location display is updated.

[0049] Please note that the above display example is merely an illustration, and the information terminal MD screen display may be shown in a different manner.

[0050] Figure 4 shows examples of displays showing the same system and parent-child relationships of equipment in the 3D display area. Note that the display examples shown in (A) and (B) are merely illustrative examples representing 3D diagrams of different areas within the facility and are not related to each other.

[0051] In Figure 4 (A): When an operation button corresponding to the display of the same system of equipment is selected in the menu button display area 314, the location of the malfunction is indicated by an arrow in the 3D display area 312, and the same system ES of the equipment where the malfunction occurred is displayed in a manner that makes it easy to identify.

[0052] In Figure 4 (B): When an operation button corresponding to the display of the parent-child relationship of equipment is selected in the menu button display area 314, the 3D display area 312 displays the parent-child relationship of the equipment with respect to the equipment that has malfunctioned in an easily identifiable manner. In the illustrated example, the indoor unit (slave unit) EC of the air conditioning equipment and the outdoor unit (master unit) EP of the outdoor equipment are displayed in different manners, and in addition, the same system ES of the air conditioning equipment is displayed in yet another different manner.

[0053] In many cases, when a maintenance worker goes to the site of a malfunction and checks the equipment, they find that the equipment in question is not malfunctioning, and the malfunction is actually occurring in related equipment. In this embodiment, even if the equipment notified as the source of the malfunction is not malfunctioning after going to the site based on the information provided by Application 300, it is possible to check the same system and parent-child relationships of the equipment on the spot to find the true source of the malfunction, obtain the necessary information to address the equipment on-site, take action, and submit a response report via Application 300 on the spot.

[0054] Thus, according to this embodiment, all or most of the series of tasks related to troubleshooting can be completed on-site, without having to return to one's room to search for further relevant information before going back to the site, or to return to one's room after the task is completed to submit a report. This shortens the time required to complete the task, including information retrieval and the execution of troubleshooting work, and allows for faster sharing of the status of troubleshooting among relevant parties, thereby significantly improving the efficiency of troubleshooting at the facility.

[0055] [Processing in inspection work] Figure 5 is a flowchart showing an example of the inspection process performed during daily inspection work in the maintenance support system 1. When facility personnel perform inspection work, they carry an information terminal (MD) when patrolling the facility, just as they do when addressing facility malfunctions. The inspection process is primarily executed by application 300. The following is a chronological explanation.

[0056] Step S1: The location of the information terminal MD, i.e., the current location of the facility staff, is automatically detected.

[0057] Steps S2-S4: An area corresponding to the current location detected in step S1 is identified (step S2), a judgment model associated with that area is selected (step S3), and environmental information is collected using sensors related to that judgment model (step S4). The type of judgment model selected varies depending on the area's conditions; sometimes only one judgment model is selected, and sometimes multiple types of judgment models are selected. If the selected judgment model includes a sound judgment model, the equipment installed in that area is further identified.

[0058] [Decision Model] Figure 6 shows the types of judgment models and the input / output information for each judgment model. In this embodiment, six types of judgment models are provided, each corresponding to one of the six environmental elements: sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose, in order to make judgments (detection of environmental abnormalities).

[0059] The sound judgment model is a model that has been trained on the operating sounds of each piece of equipment during normal operation (stable operation, normal shutdown, etc.). When equipment information and operating sounds detected by a microphone are input, the model outputs a judgment result predicting whether the detected operating sounds correspond to the normal state of the target equipment, that is, whether the operating sounds of the target equipment are abnormal or not.

[0060] The temperature judgment model is a learned model that has been trained on the normal ambient temperature for each area (room, location, etc.) within a facility. When area information and ambient temperature detected by a temperature sensor are input, it outputs a judgment result predicting whether the detected ambient temperature corresponds to the normal state of the target area, that is, whether the temperature of the target area is abnormal or not.

[0061] The odor judgment model is a learned model that has been trained on the normal environmental odors for each area (room, location, etc.) within a facility. When area information and environmental odors detected by odor sensors are input, the model outputs a judgment result predicting whether the detected environmental odor corresponds to the normal state of the target area, that is, whether the odor in the target area is abnormal or not.

[0062] The carbon monoxide concentration determination model is a learned model that has been trained on the normal carbon monoxide concentration for each area (room, location, etc.) within a facility. When area information and the carbon monoxide concentration measured by a carbon monoxide meter are input, the model outputs a determination result predicting whether the measured carbon monoxide concentration corresponds to the normal state of the target area, that is, whether the carbon monoxide concentration in the target area is abnormal or not.

[0063] The carbon dioxide concentration judgment model is a learned model that has been trained on the normal carbon dioxide concentration for each area (room, location, etc.) within a facility. When area information and the carbon dioxide concentration measured by a carbon dioxide concentration meter are input, the model outputs a judgment result predicting whether the measured carbon dioxide concentration corresponds to the normal state of the target area, that is, whether the carbon dioxide concentration in the target area is abnormal or not.

[0064] The radiation dose judgment model is a learning model that has been trained on the normal radiation levels for each area (room, location, etc.) within a facility. When area information and radiation levels measured by a dosimeter are input, it outputs a judgment result predicting whether the measured radiation level corresponds to the normal state of the target area, that is, whether the radiation level in the target area is abnormal or not.

[0065] In the above example, the judgment models are constructed by using machine learning to analyze the normal environmental information. However, if it is possible to adequately prepare both the normal and abnormal environmental information, the judgment models may be constructed by using machine learning to analyze both the normal and abnormal environmental information, and in that case, different learning methods may be applied.

[0066] [See Figure 5: Step S5] Step S5: The identified area information (or equipment information) and the environmental information collected in Step S4 are transmitted to the determination unit 230, and a determination is performed using the determination model corresponding to the environmental elements.

[0067] Step S6: If the judgment model determines that the situation is normal, i.e., no environmental abnormality is detected (Step S6: Yes), proceed to Step S7. On the other hand, if the judgment model determines that the situation is not normal, i.e., an environmental abnormality is detected (Step S6: No), proceed to Step S8.

[0068] Step S7: The facility staff member uses their five senses to check whether the environment at their current location is normal (whether there are any differences from usual, any unusual occurrences, etc.). If they determine that it is normal (Step S7: Yes), they proceed to Step S9. On the other hand, if they determine that it is not normal (Step S7: No), they proceed to Step S8.

[0069] Step S8: If the judgment model determines that the conditions do not correspond to normal conditions (Step S6: No), or if the equipment staff determines that the conditions are not normal (Step S7: No), that is, if an environmental anomaly is determined to be occurring in the current area, it is assumed that there may be some malfunction in the equipment, and the environmental anomaly response process is executed. In this process, a malfunction warning is first registered in the database, which triggers notifications to various locations, provision of checklists, and inspection work according to the checklists. The specific details of the environmental anomaly response process will be described in detail later with reference to another diagram.

[0070] Step S9: If the maintenance worker has finished inspecting all areas of the facility (Step S9: Yes), the patrol is completed, and the inspection process is finished. On the other hand, if there are still areas that have not yet been inspected, the maintenance worker continues the patrol (Step S9: No), and the procedures described in Steps S1 to S8 above are repeated for the other areas.

[0071] The above procedure example is merely an example and is not limited to it. Furthermore, environmental information detected in each area during the inspection process, including judgments made by facility staff, is stored in the database by the judgment unit 230. The stored data can be used as a training dataset for each judgment model, and by further training as needed or periodically, the accuracy of the judgment (the accuracy of predictions by the judgment model) can be improved.

[0072] [Environmental Anomaly Response Processing] Figure 7 is a flowchart showing an example of the procedure for responding to environmental anomalies. The following explanation will follow this example procedure.

[0073] Steps S11 and S12: A malfunction warning is registered in the database (Step S11), and a trigger is executed in the database in conjunction with this, and a checklist corresponding to the content of the registered malfunction warning, i.e., the content of the detected environmental anomaly, is selected (Step S12).

[0074] Steps S13-S15: In response to the registration of a malfunction warning, the warning notification unit 240 sends a warning notification to the central monitoring system 100 (Step S13), a check request is sent to the corresponding facility staff member, and the checklist selected in Step S12 is provided (Step S14), and the processing status of the database is updated (Step S15). At this time, the database also records information such as the date and time the warning notification was sent and the staff ID of the facility staff member designated as the recipient of the warning notification. For the facility staff member, the check request becomes the warning notification.

[0075] Step S16: When application 300 receives a check request, information such as the travel route from the current location to the area where the malfunction warning was issued is displayed on the screen. Using this information as a reference, the equipment staff member goes to the site and performs the check routine on-site according to the checklist displayed on the screen.

[0076] Step S17: The maintenance worker uses their five senses to check whether the site environment is normal or not (whether there are any differences from usual, any unusual occurrences, etc.). If they determine that it is normal (Step S17: Yes), they proceed to Step S18. On the other hand, if they determine that it is not normal (Step S17: No), they proceed to Step S19.

[0077] Step S18: When the equipment operator enters the inspection results and status into the input form for the inspection report related to the malfunction warning displayed on the screen, the processing status in the database is updated (Step S15). At this time, the database also records information such as the date and time the inspection was performed and notes on the inspection results.

[0078] Step S19: A request for maintenance work is registered in the database via the input form for the inspection report related to the malfunction warning displayed on the screen. In response, a trigger is executed in the database, sharing the request with the central monitoring system 100, which then carries out subsequent procedures related to the maintenance work.

[0079] According to the embodiment described above, the following advantages can be obtained. (1) When a malfunction occurs in equipment installed at the facility and an error notification is sent, or when an environmental anomaly is detected and a malfunction warning is registered and a warning notification is sent, the facility is displayed in 3D based on BIM data on the screens of the central monitoring system 100 and the information terminal MD (application 300), and the location corresponding to the notification (location of the malfunction, location of the malfunction warning registration) is mapped and displayed on the 3D display, so that the staff on the central monitoring side and the facility's equipment personnel can easily and concretely grasp, visually, where the problem is occurring or may be occurring.

[0080] (2) When an error notification is sent to application 300, the location of the defect is mapped and displayed on a 3D display based on BIM data in a manner corresponding to the current status. In addition, the route to the selected defect location from the current location is displayed in an easily identifiable manner. Depending on the operation, information such as the key required to move to the defect location, the type of tool required corresponding to the error ID, and the manual for the equipment where the defect occurred can be displayed. As a result, all or most of the series of tasks related to defect response can be completed on-site, significantly improving the efficiency of defect response work and significantly reducing the time required.

[0081] (3) In application 300, by selecting the corresponding operation button, the same system and parent-child relationships of the equipment that has been notified of a malfunction can be displayed. Therefore, even if on-site inspection reveals that the notified equipment does not have a malfunction, the same system and parent-child relationships of the equipment can be checked on the spot to pinpoint the true source of the malfunction, and the information necessary to repair the equipment can be obtained on-site and taken action.

[0082] (4) After receiving an error notification or warning notification and the facility staff takes action, information such as the details of the action is registered in the database and the status is updated, and historical information regarding the maintenance and management of the equipment is accumulated. This historical information can be used to improve the operating rate of each piece of equipment (MTBF, MTTR, etc.).

[0083] (5) During the inspection process, the inspection process (Figure 5) is executed, and environmental abnormalities are automatically detected using sensors and judgment models corresponding to each area of ​​the facility. This improves the efficiency of the inspection work and reduces the time required. Furthermore, if an abnormality is detected, a malfunction warning is registered in the database and a warning notification is sent to the central monitoring system 100 and application 300. This allows relevant parties to quickly share information about the environmental abnormality and take appropriate action.

[0084] (6) During the inspection process (Figure 5), if the judgment model determines that the situation is normal (no environmental abnormalities have occurred), the equipment operator's five senses will be used to confirm whether the current location is normal or not. If it is determined that the situation is not normal, a malfunction warning will be registered, and the information at that time will be registered in the database. This allows the know-how of skilled equipment operators (tacit knowledge based on experience in determining whether the situation is normal or not) to be extracted into the database (converted into explicit knowledge), leading to safer and more reliable inspection work.

[0085] (7) Environmental information can be collected using sensors mounted on or connected to the information terminal MD carried by the facility staff. Therefore, even in locations where sensors are not installed or where installation is difficult, necessary environmental information can be collected and it can be determined whether or not the conditions at that location are normal.

[0086] The present invention can be implemented in various ways without being limited to the embodiments described above.

[0087] In the embodiment described above, six types of judgment models are provided, corresponding to six types of environmental elements: sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose. However, the types of judgment models are not limited to these, and other judgment models corresponding to other environmental elements may be provided.

[0088] In the embodiment described above, inspection processing (Figure 5) is performed in each area of ​​the facility in conjunction with the current location of the information terminal MD carried by the facility staff performing the inspection work, and environmental information is collected via application 300 to determine whether or not it is in a normal state. However, information detected by sensors installed in various locations throughout the facility may be acquired periodically, or only under predetermined circumstances, by wireless communication or the like by the management server 200 (determination unit 230) without going through application 300, and a determination may be made as to whether or not the detected information corresponds to the normal state of the area where the sensor is installed. With such a configuration, if a serious environmental abnormality occurs on site (for example, if the carbon monoxide concentration exceeds the permissible value), this can be quickly grasped, and the danger can be notified before the facility staff go out to patrol the facility, making it possible to have them take alternative action without going to the site.

[0089] Furthermore, all other examples shown with illustrations in the embodiments are merely preferred examples, and it goes without saying that modifications can be made as appropriate when implementing the present invention. [Explanation of Symbols]
