The central monitoring system 100 has, for example, a display section 110 and an error notification section 120 . The display unit 110 displays the equipment status, operating conditions, and the like on a screen for central monitoring. The error notification unit 120 receives an error notification and transmits the error notification to the application 300 when a failure occurs in any of the facilities monitored by the central monitoring system 100 . In addition, regarding the error notification, the display unit 110 stereoscopically displays the facility on the screen, and maps the location of the failure corresponding to the error notification (installation location of the equipment where the failure occurred), the current location of the facility staff, etc. on the stereoscopic display. Displayable.

The management server 200 has, for example, a facility management database 210, a BIM database 220, a determination section 230, a warning notification section 240, and the like.

The facility management database 210 is a database for managing various information related to facility management. In addition to a response history table that accumulates history information (status, update date, response details, etc.) of responses to notifications and warning notifications described later, a table that manages the status of equipment and a table that stores other related information have.

The BIM database 220 stores BIM models corresponding to facility as-built drawings and views that can display the BIM models in various ways (hereinafter, the BIM models and their views are collectively referred to as "BIM data"). .). The determination unit 230 determines whether the degree of environmental elements (for example, sound, temperature, etc.) detected by various sensors in each area of the facility corresponds to the normal state, that is, whether an environmental abnormality has occurred. Whether or not it is determined using a model (hereinafter referred to as “determination model 232”) that has undergone machine learning in advance using actual detection data for these environmental elements as a learning data set. The types of the determination model 232 and their inputs and outputs will be described later in detail with reference to other drawings. Details of the warning notification unit 240 will also be described later.

The information terminal MD is equipped with sensors such as a position sensor PS and a microphone MC, and these are used by the application 300 depending on the situation. In addition, the position of the information terminal MD detected by the position sensor PS, that is, the current location of the facility staff can always be confirmed from the central monitoring system 100. In addition, the microphone MC, speaker SP, etc. are configured to be operable from the central monitoring system 100 .

The type and the like are obtained from the facility management database 210 (facility information table) and displayed on the screen. The update registration unit 340 displays a response report input form on the screen of the information terminal MD, receives inputs such as the details of the response from the facility staff who performed the response, the status after the response, etc., and stores it in the facility management database 210 (response history table ).

The determination window section 350 refers to the facility management database 210 to identify the area to which the current location of the information terminal MD corresponds and facilities installed around the current location, and selects a determination model that can be used at the current location. Then, the determination window unit 350 transmits detection information of environmental elements detected by a sensor mounted on or connected to the information terminal MD or a sensor installed at the site and information on the current location to the determination unit 230, and makes a determination. It causes the unit 230 to make a judgment using the judgment model corresponding to the environmental element, and receives the judgment result. The fault warning unit 360 issues a fault warning indicating that there is a possibility that a fault has occurred in the facilities around the current location when the determination unit 230 determines that the equipment is not normal or when the facility staff determines that the equipment is not normal. Register in database 210 .

When the malfunction warning is registered in the facility management database 210, the warning notification unit 240 transmits the warning notification to the central monitoring system 100 and the application 300. FIG.

When the central monitoring system 100 receives the warning notification, the display unit 110 acquires the BIM data of the facility from the BIM database 220, stereoscopically displays the facility on the screen for central monitoring, and displays the area where the defect warning is given on the stereoscopic display. is mapped, and information on the environmental factors (types of environmental factors, their detected values, etc.) that caused the failure warning are also displayed.

On the other hand, when the application 300 receives the warning notification, first, the display processing unit 310 stereoscopically displays the facility on the screen of the information terminal MD based on the BIM data acquired from the BIM database 220, and a fault warning is issued on the stereoscopic display. map the area. At this time, information (type of environmental element, detected value thereof, etc.) related to the environmental element that caused the trouble warning may be displayed together. Further, the information providing unit 330 acquires a checklist composed of a plurality of items corresponding to the details of the defect warning from the facility management database 210 (for example, a checklist table) and displays it on the screen. Then, after the facility staff has performed the inspection according to the checklist, the update registration unit 340 displays the inspection report input form regarding the failure warning on the screen, and the inspection result by the facility staff who has performed the inspection according to the checklist. and status after inspection are received and registered in the facility management database 210 (response history table).

In this way, in the maintenance work support system 1, the central monitoring system 100, the management server 200, and the application 300 cooperate with each other, so that the application 300 is sent to the facility staff when an error notification or warning notification is given. Various information is provided through In addition, when the facility staff visits the site and responds based on the provided information, the status is updated by the facility staff, the contents of the response, etc. are registered in the facility management database 210, and the history information regarding the maintenance and management of the facility is accumulated. To go. The history 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 facility, analyze the tendency of defects, and the like.

In the illustrated example, the microphone MC and the temperature sensor TS mounted on the information terminal MD are used as sensors, but the types of sensors (types of environmental elements to be detected) are not limited to these. In this embodiment, the types of environmental elements are assumed to be sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose. For detection of environmental elements, a sensor mounted on or connected to the information terminal MD may be used, or information detected by a sensor installed at the site may be acquired by wireless communication and used.

[Screen display by application]
FIG. 3 is a diagram showing an example of display on the screen of the information terminal MD by the application 300. As shown in FIG. The screen is provided with, for example, a stereoscopic display area 312 , a menu button display area 314 , and a list display area 316 . The sizes of the three-dimensional display area 312 and the list display area 316 can be enlarged or reduced by the facility staff as necessary.

In the stereoscopic display area 312, the facility is stereoscopically displayed based on the BIM data, and a mark and a management number are displayed at the place where the problem occurs. The mark is displayed in a color according to the status so that the current response status can be easily identified. For example, if the problem has just occurred, the mark will be displayed in red, if the observer responded, the mark will be displayed in yellow, and if the response is being processed, the mark will be displayed in green. The mark is displayed in white when it is waiting for approval of

Various operation buttons for switching the display contents of the stereoscopic display area 312 are arranged in the menu button display area 314 . By selecting the corresponding operation button, the equipment staff can enlarge or reduce the display, switch the view (display with different views), display the movement route from the current location to the location where the problem occurred, display the same system of equipment, display the equipment It is possible to display the parent-child relationship of

In the list display area 316, a list of information on troubles that occurred within a predetermined period is displayed in reverse chronological order. The list display includes the management number (No), the time when the problem occurred, the ID of the equipment where the problem occurred, the relevant area, the error ID, the current status, the display mode of the mark on the three-dimensional display, and the staff ID of the staff member in charge of the equipment. , information such as the telephone number of the facility staff is displayed. The display contents of the list display area 316 can be switched. For example, by selecting a predetermined part in the list, the facility staff can display the response report input form, display the response report list, or display related information such as manuals associated with each facility. You can

For example, when the facility staff selects one of the failure locations displayed in the three-dimensional display area 312, a failure detail window is popped up so as to overlap the three-dimensional display of the equipment, and detailed information about the selected failure is displayed. be done. Then, when the [Display] button of the related information displayed in the defect details window is selected, the pop-up window closes and the travel route from the current location to the selected defect occurrence location is displayed on the 3D display in an easy-to-identify manner. In addition, a list display area 316 displays a key required to move to the location where the problem occurred, the type of necessary tool corresponding to the error ID, the manual of the equipment in which the problem occurred, and the like. Further, when the facility staff moves along the displayed route, the information on the facility staff's current location (the position of the information terminal MD) is updated accordingly, and the display of the current location is updated.

Note that the display example described above is merely an example, and the screen display of the information terminal MD may be performed in a different manner.

FIG. 4 is a diagram showing a display example of the same system of facilities and the parent-child relationship in the stereoscopic display area. It should be noted that the display examples shown in (A) and (B) represent three-dimensional views of different areas within the facility for illustrative purposes only, and are not related to each other.

(A) in FIG. 4: When the operation button corresponding to the display of the same system of equipment is selected in the menu button display area 314, an arrow indicates the place where the problem occurs and the problem occurs in the stereoscopic display area 312. The same system ES of the installed equipment is displayed in an easy-to-distinguish manner.

(B) in FIG. 4: When the operation button corresponding to the display of the parent-child relationship of the equipment is selected in the menu button display area 314, the parent-child relationship of the equipment in which the problem has occurred is displayed in the stereoscopic display area 312 so that the parent-child relationship can be easily identified. displayed in the form. 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. Furthermore, it is displayed in a different manner.

It is not uncommon for equipment personnel to go to the location where the problem occurred and check the equipment, and as a result, there is no problem in that equipment, and in fact, the problem has occurred in related equipment. In this embodiment, based on the information provided by the application 300, even if there is no problem with the equipment notified as the source of the problem, the same system and parent-child relationship of the equipment can be confirmed on the spot. It is possible to find out the true source of the problem by using the application 300, to obtain the information necessary for dealing with the equipment at the site, to take action, and to report the action on the spot via the application 300.

As described above, according to the present embodiment, there is no need to go back to the living room and search for further related information before returning to the site, or return to the living room after dealing with the problem and report the response. Since all or most of the series of work related to the response can be completed locally, it is possible to shorten the time required to complete the response, including searching for information and implementing the response work. The information can be shared among the parties concerned more quickly, and the efficiency of responding to troubles at the facility can be greatly improved.

[Processing in inspection work]
FIG. 5 is a flow chart showing a procedure example of inspection processing executed in the course of daily inspection work in the maintenance work support system 1. As shown in FIG. An equipment worker who performs inspection work carries an information terminal MD when patrolling the facility, in the same way as when dealing with troubles in the facility. Inspection processing is mainly executed by the application 300 . The following is a description in chronological order.

Step S1: The position of the information terminal MD, that is, the current location of the facility staff is automatically detected.

Steps S2 to S4: The area corresponding to the current location detected in step S1 is specified (step S2), the judgment model associated with the area is selected (step S3), and the sensors related to the judgment model are selected. Environmental information is collected using the (step S4). The type of determination model to be selected varies depending on the situation of the area, and there are cases where only one determination model is selected, and there are cases where multiple types of determination models are selected. Also, when the selected determination model includes the sound determination model, the equipment installed in the area is further specified.

[Judgment model]
FIG. 6 is a diagram showing types of decision models and input/output information of each decision model. In this embodiment, in order to determine (environmental anomaly detection) six types of environmental factors: sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose, six types corresponding to each We have a judgment model for

The sound judgment model is a model that learns the operation sound of each facility during normal operation (during stable operation, normal stop, etc.). A result of predicting whether or not the sound corresponds to the normal state of the target facility, that is, whether or not the operating sound of the target facility is abnormal, is output as a determination result.

The temperature judgment model is a learning model that learns the normal environmental temperature for each area (room, place, etc.) in the facility. A result of predicting whether or not the environmental temperature corresponds to the normal state of the target area, that is, whether or not the temperature of the target area is abnormal, is output as a determination result.

The odor determination model is a learning model that learns environmental odors in normal times for each area (room, place, etc.) within the facility. A result of predicting whether or not the environmental odor corresponds to the normal state of the target area, that is, whether or not the odor of the target area is abnormal is output as a determination result.

The carbon monoxide concentration determination model is a learning model that learns the normal carbon monoxide concentration for each area (room, place, etc.) in the facility. When the carbon concentration is input, the result of predicting whether the measured carbon monoxide concentration corresponds to the normal state of the target area, that is, whether the carbon monoxide concentration of the target area is abnormal or not, is used as the judgment result. Output.

The carbon dioxide concentration determination model is a learning model that has learned the normal carbon dioxide concentration for each area (room, place, etc.) in the facility, and the area information and the carbon dioxide concentration measured by the carbon dioxide concentration meter. When input, the result of predicting whether or not the measured carbon dioxide concentration corresponds to the normal state of the target area, that is, whether or not the carbon dioxide concentration of the target area is abnormal is output as the determination result.

The radiation dose determination model is a learning model that learns the normal radiation dose for each area (room, place, etc.) within the facility. Whether or not the radiation dose obtained corresponds to the normal state of the target area, that is, whether or not the radiation dose of the target area is abnormal is output as a judgment result.

In the above example, each judgment model is built by machine learning the environmental information during normal times, but if it is possible to prepare sufficient environmental information during abnormal times together with the environmental information during normal times may construct each judgment model by machine learning environmental information in normal and abnormal times, and in that case, different learning methods may be applied.

[See FIG. 5: Step S5]
Step S5: The specified area information (or facility information) and the environment information collected in step S4 are sent to the determination unit 230, and determination is performed using a determination model corresponding to the environmental elements.

Step S6: If the determination model determines that the state corresponds to the normal state, that is, if no environmental abnormality is detected (step S6: Yes), the process proceeds to step S7. On the other hand, if it is determined not to correspond to the normal state, that is, if an environmental abnormality is detected (step S6: No), the process proceeds to step S8.

Step S7: The facility staff uses his five senses to check whether the environment at the current location is normal (whether there is anything different from usual, whether there is any discomfort, etc.), and if it is determined to be normal, (step S7: Yes), the process proceeds to step S9. On the other hand, if it is determined that the system is not normal (step S7: No), the process proceeds to step S8.

Step S8: If it is determined that the determination model does not correspond to the normal state (Step S6: No), or if the facility staff determines that it is not normal (Step S7: No), that is, the environmental abnormality in the current area is occurring, it is assumed that there is a possibility that some kind of trouble has occurred in the facility, and the environmental anomaly handling process is executed. In this process, first, a malfunction warning is registered in the database, and with this as a trigger, various places are notified, a checklist is provided, and inspection work is performed according to the checklist. Specific contents of the environmental abnormality handling process will be described later in detail with reference to other drawings.

Step S9: When the facility staff has finished inspecting all areas of the facility (Step S9: Yes), the patrol ends, and the inspection process ends. On the other hand, if there are areas that have not yet been inspected, the facility staff continues patrol (step S9: No), and the above-described steps S1 to S8 are repeated in other areas.

It should be noted that the above procedure example is merely an example, and is not limited to this. In addition, the environmental information detected in each area during the inspection process is accumulated in the database by the judgment unit 230, including the judgments made by the facility staff. , the determination accuracy (accuracy of prediction by the determination model) can be improved by further learning as needed or periodically.

[Environmental abnormality response processing]
FIG. 7 is a flow chart showing an example of the procedure of the environmental abnormality handling process. An example procedure will be described below.

Steps S11 and S12: A failure warning is registered in the database (step S11), and a trigger is executed in the database in conjunction with this, and a check is made according to the content of the registered failure warning, that is, the content of the detected environmental abnormality. A list is selected (step S12).

Steps S13 to S15: In response to the registration of the trouble warning, the warning notification unit 240 transmits a warning notification to the central monitoring system 100 (step S13), and a check request is transmitted to the corresponding facility personnel, and step S12. is provided (step S14) and the processing status in the database is updated (step S15). At this time, information such as the transmission date and time of the warning notification and the staff ID of the facility staff designated as the transmission destination of the warning notification is also recorded in the database. For the facility staff, the check request serves as a warning notice.

Step S16: When the application 300 receives the check request, information such as the moving route from the current location to the area for which the trouble warning was given is displayed on the screen. While referring to this information, equipment personnel go to the site and carry out a check routine at the site according to the checklist displayed on the screen.

Step S17: The facility staff uses his/her five senses to check whether the site environment is normal (whether there is anything different from usual, whether there is any discomfort, etc.), and if it is determined to be normal (step S17: Yes), the process proceeds to step S18. On the other hand, if it is determined that the system is not normal (step S17: No), the process proceeds to step S19.

Step S18: When the facility staff inputs the inspection result, status, etc. to the input form of the inspection report regarding the failure warning displayed on the screen, the processing status of the database is updated (step S15). At this time, information such as the date and time when the inspection was performed and a memo of the inspection result is also recorded in the database.

Step S19: A maintenance work implementation request is registered in the database via the inspection report input form regarding the defect warning displayed on the screen. In response to this, a trigger is executed in the database, so that the execution request is shared with the central monitoring system 100, and the central monitoring system 100 performs subsequent procedures regarding maintenance work.

According to the embodiment described above, the following advantages are obtained.
(1) When a failure occurs in equipment installed in a facility and an error notification is sent, or when an environmental abnormality is detected and a failure warning is registered and a warning notification is sent, the central monitoring system 100 and information Facilities are displayed three-dimensionally on each screen of the terminal MD (application 300) based on BIM data, and the position corresponding to the notification (location of trouble occurrence, trouble warning registration place) is mapped and displayed on the three-dimensional display. , where a problem is occurring or may occur, can be easily and concretely grasped visually by the staff on the central monitoring side and the facility staff.

(2) When the application 300 is notified of an error, the location of the failure occurrence is mapped and displayed according to the current status on the stereoscopic display based on the BIM data, and the location of the failure occurrence selected from the current location is displayed. Information such as the key required to move to the location where the problem occurred, the type of required tool corresponding to the error ID, the manual of the equipment where the problem occurred, etc. can be displayed, all or most of the series of work related to troubleshooting can be completed on site, and the work efficiency of troubleshooting can be greatly improved while the required time can be greatly shortened.

(3) By selecting the corresponding operation button in the application 300, it is possible to display the same system and the parent-child relationship of the facility notified that the failure has occurred. Even if there is no problem with the equipment, it is possible to find the true source of the problem by checking the same system and parent-child relationship of the equipment on the spot. It can be carried out.

(4) After receiving an error notification or warning notification and responding to it, the information such as the details of the response is registered in the database, the status is updated, and the history information related to the maintenance and management of the equipment is accumulated. These history information can be used to improve the operation rate (MTBF, MTTR, etc.) of each facility.

(5) Inspection processing (Fig. 5) is executed in the course of inspection work, and environmental abnormalities are automatically detected using sensors and judgment models corresponding to each area of the facility, so the work efficiency of inspection work is improved. improve and reduce the time required. In addition, when 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 the application 300, so that information about the environmental abnormality can be quickly shared among the concerned parties, can deal with it.

(6) In the course of the inspection process (Fig. 5), if the determination model determines that the state corresponds to the normal state (no environmental abnormality has occurred), the facility staff's five senses indicate that the current location is normal. If it is determined to be abnormal, a malfunction warning is registered, and the information at that time is registered in the database. Tacit knowledge based on experience regarding judgment) can be absorbed into a database (converted into explicit knowledge), which can lead to the realization of safer and more reliable inspection work.

(7) Environmental information can be collected using sensors mounted on or connected to the information terminal MD carried by the facility staff. can be collected to determine if it applies to normal conditions at the location.

The present invention can be modified in various ways without being limited to the above-described embodiments.

In the above-described embodiment, six types of determination models are provided corresponding to the six types of environmental elements of sound, temperature, odor, carbon monoxide concentration, carbon dioxide concentration, and radiation dose. The types are not limited to this, and other judgment models corresponding to other environmental elements may be further provided.

In the above-described embodiment, the inspection process (FIG. 5) is executed in each area of the facility in conjunction with the current location of the information terminal MD carried by the facility staff who performs the inspection work, and environmental information is collected via the application 300. However, the information detected by the sensors installed in various parts of the facility is periodically or only under a predetermined situation, without using the application 300. For example, the management server 200 (determination unit 230) may determine whether or not the detected information corresponds to the normal state of the installation area of the sensor. By adopting such a configuration, if a serious environmental abnormality occurs at the site (for example, the carbon monoxide concentration exceeds the allowable value, etc.), the fact can be quickly grasped and the equipment staff Before visiting the facility to patrol the facility, the operator can be notified of the danger, and can be made to take other measures without going to the site.

In addition, it goes without saying that all of the examples shown in the drawings in the embodiments are merely preferable examples, and that modifications can be made as appropriate when implementing the present invention.
