Description

Equipment maintenance system, equipment operation terminal and portable terminal

The present invention relates to an equipment maintenance system for maintaining equipment and a equipment operation terminal and a portable terminal for a user to input an operation instruction to the equipment.

Conventionally, when equipment fails, a user who uses the equipment calls a customer center of the equipment to inquire about a countermeasure for the failure. Since the user is not familiar with the equipment when making an inquiry, it is difficult to accurately convey the contents regarding the failure of the equipment. If the maintenance worker who received the inquiry goes to the place of the equipment without knowing the details of the failure, it may not be possible to repair the part brought with it even if the cause of the failure is identified. In this case, the maintenance worker takes time and effort to get the necessary parts to the service base.

Then, the installation apparatus which transmits a detailed failure content simply to a service base from a user is known (for example, refer patent document 1). When a failure occurs, the equipment of Patent Document 1 converts equipment information including an error code and the location of the equipment into a two-dimensional code and displays the same. When the user captures a two-dimensional code with the camera of the portable terminal, the portable terminal transmits image data of the two-dimensional code to the diagnosis server. The diagnosis server analyzes the image data, diagnoses the fault content, and sends the diagnosis result to the service station.

JP 2004-265317 A

In Patent Document 1, image data of a two-dimensional code including device information is directly transmitted to a server. However, in the two-dimensional code, the amount of information that can be transmitted is limited. Therefore, much information such as the operation state of the equipment can not be transmitted, and the server can not diagnose with high accuracy. On the other hand, even if the user operates the portable terminal to supplement and input information necessary for failure diagnosis, it is not familiar with the equipment and can not determine which information is necessary.

The present invention has been made to solve the above-described problems, and provides a facility maintenance system, a facility operation terminal, and a portable terminal that allow a user to easily notify the service base of the status of the facility device.

An equipment maintenance system according to the present invention acquires equipment information that outputs equipment information including information indicating the state of equipment equipment, and acquires the equipment information from the equipment, and shapes the acquired equipment information into an abnormality notification form. And a portable terminal to transmit to the maintenance compatible terminal.

A facility operation terminal according to the present invention comprises a wireless communication unit for wirelessly communicating with a mobile terminal, a storage unit for storing facility information indicating the status of the facility device, and the mobile terminal for requesting the facility information required for the abnormality notification form. And a control unit that transmits the facility information stored in the storage unit to the portable terminal via the wireless communication unit when received from the wireless communication unit.

A portable terminal according to the present invention acquires, via the wireless communication unit, a wireless communication unit that wirelessly communicates with the facility device, and facility information indicating the state of the facility device, and shapes the acquired facility information into an abnormality notification form. And a control unit for transmitting to the maintenance compatible terminal.

According to the present invention, the portable terminal acquires facility information from the facility equipment, creates an abnormality notification form including information necessary for diagnosing an abnormality, and notifies the maintenance compatible terminal. Therefore, the user can easily notify the maintenance worker of the service base of the information on the state of the equipment.

Therefore, it is not necessary to sort the necessary information by itself from the facility information.

In step ST106, when receiving the equipment information from the equipment operation terminal 1, the control unit 33 of the portable terminal 3 stores the equipment information in the storage unit 34. Then, the control unit 33 shapes the equipment information stored in the storage unit 34 into an abnormality notification form, and displays the abnormality notification form on the display unit 31 (step ST107).

FIG. 16 is a view showing an example of an abnormality notification form displayed by the mobile terminal shown in FIG. In the air conditioning operation program executed by the control unit 33, items required for diagnosing abnormality are set in the abnormality notification form. The control unit 33 reads out the information corresponding to the item set in the abnormality notification form from the facility information, includes the read information in the abnormality notification form, and completes the abnormality notification form 84 shown in FIG. Then, the control unit 33 causes the display unit 31 to display an abnormality notification form in which information necessary for diagnosing an abnormality is embedded.

As shown in FIG. 16, the abnormality notification form 84 displays an abnormality code and models of the indoor unit 50, the outdoor unit 40, and the facility operation terminal 1. Therefore, it is not necessary for the user to input the information by operating the portable terminal 3. The user only needs to operate the portable terminal 3 and input the address where the equipment 2 is installed in the address input field 85.

The information displayed in the abnormality notification form 84 shown in FIG. 16 is displayed to show the user, and information other than the information shown in FIG. 16 may be included in the abnormality notification form. The control unit 33 may include one or both of the driving state data and the history data in the abnormality notification form. In this manner, information necessary for abnormality diagnosis is extracted from the facility information and embedded in the abnormality notification form 84. In addition, if the storage unit 34 stores information on the address of the user, the control unit 33 may read out the information on the address from the storage unit 34 and include it in the abnormality notification form. In this case, the user does not need to operate the mobile terminal 3 to input an address, and it is only necessary to confirm whether the address displayed by the display unit 31 is correct.

If the data size of the facility information is small in steps ST105 to ST107, the control unit 33 smoothly displays the abnormality notification form 84 shown in FIG. 16 on the display unit 31 after the button 82 shown in FIG. 15 is selected. You can migrate to On the other hand, when the data size of the facility information is large, the time for the portable terminal 3 to receive the facility information from the facility operation terminal 1 may be long. In this case, the control unit 33 processes the reception of the facility information in the background, and displays an icon indicating that data is being downloaded near the periphery of the screen, such as the upper portion of the screen of the display unit 31, Not to disturb the The control unit 33 may display the abnormality notification form 84 on the display unit 31 when the reception of the facility information is ended, but may display an icon indicating that the download is ended on the display unit 31. In this case, when the user operates the portable terminal 3 to select the icon indicating the end of the download, the control unit 33 shifts to a process of causing the display unit 31 to display the abnormality notification form 84.

When the user selects the button 86 indicating that the abnormality notification form is to be transmitted via the input unit 32 of the portable terminal 3 while watching the abnormality notification form 84 shown in FIG. To the maintenance compatible terminal 7 (step ST108). When the maintenance support terminal 7 receives the abnormality notification form from the portable terminal 3, the maintenance corresponding terminal 7 stores the abnormality notification form in the storage unit 71 (step ST109). Subsequently, the maintenance handling terminal 7 outputs an abnormality notification form stored in the storage unit 71 (step ST110). When the maintenance handling terminal 7 is a PC, an abnormality notification form is displayed on the output unit 73.

At the service site, the maintenance worker can refer to the abnormality notification form outputted by the maintenance compatible terminal 7 before going to the place where the equipment 2 is installed. Therefore, if the abnormality notification form includes the operation status, setting information, model information, etc., the maintenance worker must use the information included in the abnormality notification form before going to the place where the facility device 2 is installed. The cause of the abnormality occurring in the facility device 2 can be inferred.

For example, if the abnormality notification form includes model information, the maintenance worker can not only predict the abnormality occurring in the equipment 2 from the past abnormality information generated in the equipment of the same model as the equipment 2 but also the equipment Parts corresponding to 2 can be prepared in advance. If the abnormality notification form includes the operating state data, the maintenance worker can know the current operating state of the facility device 2 from the abnormality notification form. If the abnormality notification form includes history data, the maintenance worker can know the abnormality information and the change in temperature and humidity from the abnormality notification form. The maintenance worker can more reliably determine the cause of the abnormality that has occurred in the facility device 2 by referring to at least one of the temperature change and the humidity change in addition to the state indicating an abnormality. .

The maintenance worker goes to the place of the equipment 2 to identify the cause of the abnormality and procure the necessary parts and components if the information necessary for diagnosing the abnormality of the equipment 2 is insufficient. It is necessary to go back to the place of the equipment 2 again. On the other hand, in the first embodiment, the maintenance worker brings in the necessary parts and tools by grasping the information necessary for diagnosing the abnormality of the equipment 2 in advance, and places the equipment 2 You can go to Therefore, the maintenance worker can go to the place of the facility device 2 only once, and can save time and effort twice.

The case where the facility operation terminal 1 makes a connection request to the portable terminal 3 and provides facility information to the portable terminal 3 has been described with reference to steps ST104 to ST106 shown in FIG. The timing of provision of equipment information is not limited to this case. The timing of provision of the facility information may be, for example, a case where the user operates the portable terminal 3 to make the portable terminal 3 communicate with the facility operation terminal 1.

FIG. 17 is a sequence diagram showing another example of the procedure of steps ST101 to ST106 shown in FIG. The user operates the portable terminal 3 to cause the portable terminal 3 to execute the air conditioning operation program in order to change the setting of the operation state of the facility device 2. When the control unit 33 of the portable terminal 3 starts the air conditioning operation program (step ST131), the control unit 33 requests the facility operation terminal 1 to connect via the wireless communication 5 (step ST132).

When the control unit 11 of the facility operation terminal 1 receives a connection request from the portable terminal 3, the control unit 11 notifies the portable terminal 3 of a connection permission response via the wireless communication 5 (step ST133). When receiving the connection permission response from the facility operation terminal 1 via the wireless communication 5, the control unit 33 of the portable terminal 3 requests the facility information from the facility operation terminal 1 to request collection of facility information (step ST134). ). When the control unit 11 of the facility operation terminal 1 receives a request for facility information from the portable terminal 3, as described with reference to FIG. 14, the control unit 11 transmits the collected facility information to the portable terminal 3 (step ST106).

In step ST133, the control unit 11 of the facility operation terminal 1 may include information indicating that an abnormality has occurred in the connection permission response. In this case, the control unit 33 of the mobile terminal 3 may cause the display unit 31 to display a message indicating that an abnormality has occurred in the facility device 2. For example, the control unit 33 may cause the display unit 31 to display the notification request image shown in FIG. On the other hand, when no abnormality occurs in the equipment 2, when the control unit 11 of the equipment operation terminal 1 receives a request for equipment information from the portable terminal 3 (step ST134), the abnormality occurs in step ST106. Information indicating the absence may be transmitted to the mobile terminal 3.

In the first embodiment, the mobile terminal 3 wirelessly communicates with the facility operation terminal 1, but the mobile terminal 3 may directly wirelessly communicate with the facility device 2. In this case, in the configuration shown in FIG. 3, the sensor group 15 and the short distance wireless communication unit 16 are provided in the air conditioned space, and one of the control devices 45 and 55 is the control unit 11 or the storage unit 12. And the function of the communication unit 14.

Moreover, although the case where the number of service bases is one has been described in the first embodiment, a plurality of service bases may be provided corresponding to a plurality of areas. In this case, a server may be provided which assigns the abnormality notification form transmitted from the mobile terminal 3 to any one of a plurality of service bases. FIG. 18 is a diagram showing another configuration example of the equipment maintenance system including the equipment operation terminal according to the first embodiment of the present invention. As shown in FIG. 18, a reception server 6 connected to the network 9 is provided. When the reception server 6 receives the abnormality notification form from the portable terminal 3, the reception server 6 reads the address information from the abnormality notification form, and transmits the abnormality notification form to the maintenance compatible terminal 7 of the service base installed at a position closest to the address. You may

The facility maintenance system of the first embodiment includes a facility device 2 and a portable terminal 3. The facility device 2 transmits facility information indicating the state to the mobile terminal 3. When acquiring the facility information device from the facility device 2, the portable terminal 3 shapes the facility information into an abnormality notification form, and transmits the anomaly notification form to the maintenance compatible terminal 7.

In the first embodiment, the portable terminal 3 acquires facility information from the facility device 2, creates an abnormality notification form including information necessary for diagnosing an abnormality, and notifies the maintenance compatible terminal 7 of the form. Therefore, even if the user is not familiar with the equipment 2, the user can easily notify the maintenance worker of the service base of the information on the state of the equipment 2. As a result, the maintenance worker at the service base can go to the facility equipment 2 after determining the cause of the abnormality by referring to the abnormality notification form output by the maintenance compatible terminal 7.

Further, in the first embodiment, the facility device 2 does not need to sort out the information necessary for diagnosing the abnormality from the information stored in the storage unit 12, so the load of the information processing is reduced. It is not necessary to increase resources including the arithmetic processing device and the memory necessary for the process of extracting information necessary for diagnosis of abnormality from the facility information to the facility device 2.

Second Embodiment
In the first embodiment, facility information indicating the state of the facility device 2 is collected and provided to the mobile terminal 3 by wireless communication, and the mobile terminal 3 extracts information necessary for diagnosing an abnormality from the facility information. In the second embodiment, the facility device 2 provides the mobile terminal 3 with facility information in a two-dimensional code. The second embodiment is effective when the amount of information of equipment information is equal to or less than the amount of information included in the two-dimensional code. Further, the second embodiment is also effective when one or both of the equipment 2 and the portable terminal 3 do not have the short distance wireless communication unit.

The configuration of the equipment maintenance system of the second embodiment will be described. In the second embodiment, the detailed description of the same configuration as that of the first embodiment is omitted. FIG. 19 is a block diagram showing an example of configuration of a portable terminal according to Embodiment 2 of the present invention. The portable terminal 3 a has a photographing unit 36 instead of the short distance wireless communication unit 35 as compared to the portable terminal 3 shown in FIG. 12. The imaging unit 36 includes a lens and an imaging device, which are not shown.

After activating the air conditioning operation program, the control unit 33 activates the imaging unit 36 when a photographing instruction is input. When the control unit 33 receives the image data of the two-dimensional code captured by the imaging unit 36 from the imaging unit 36, the control unit 33 stores the image data in the storage unit 34. The control unit 33 analyzes the image data stored in the storage unit 34 to acquire facility information.

The operation procedure of the facility operation terminal 1 of the second embodiment will be described. FIG. 20 is a sequence diagram showing an operation procedure of the facility maintenance system according to the second embodiment of the present invention. Here, the case where the portable terminal 3 has already started the air conditioning operation program will be described.

If the control unit 11 of the facility operation terminal 1 detects an abnormality (step ST201), the control unit 11 records the abnormality information in the storage unit 12 (step ST202). At this time, the control unit 11 may cause the display unit 10 to display a message indicating that an abnormality has occurred. The control unit 11 converts the facility information into a two-dimensional code. Further, the control unit 11 causes the display unit 10 to display the plurality of converted two-dimensional codes (step ST203).

When the user sees the message displayed by the display unit 10 of the facility operation terminal 1 and recognizes that an abnormality has occurred in the facility device 2, the user directs the imaging unit 36 to the display unit 10 and instructs the portable terminal 3 to perform imaging. Enter When the photographing instruction is input, the control unit 33 of the portable terminal 3 activates the photographing unit 36 to make the photographing unit 36 photograph a two-dimensional code (step ST204). Control unit 33 stores the image data received from imaging unit 36 in storage unit 34 (step ST205).

Subsequently, control unit 33 analyzes the image data stored in storage unit 34 (step ST206). Then, the control unit 33 converts the image data into facility information. Thereafter, as in the first embodiment, the control unit 33 shapes the equipment information into the abnormality notification form and causes the display unit 31 to display the form (step ST207). The processing of steps ST208 to ST210 shown in FIG. 20 is the same as the processing of steps ST108 to ST110 shown in FIG.

Although the case where the amount of information of equipment information is equal to or less than the amount of information included in the two-dimensional code has been described with reference to FIG. 20, the amount of information of equipment information is greater than the amount of information included in one two-dimensional code. If it is large, the facility information may be distributed to a plurality of two-dimensional codes. An example of the operation in this case will be described with reference to FIG.

In step ST203 shown in FIG. 20, the control unit 11 causes the display unit 10 to display a plurality of two-dimensional codes. At that time, the control unit 11 generates one two-dimensional code and displays it on the display unit 10 for a predetermined time each time the storage unit 34 reads out information of an amount that can be converted into one two-dimensional code from the facility information. Let The fixed time is, for example, 5 seconds. Thus, the facility device 2 distributes facility information to a plurality of two-dimensional codes and outputs the same.

In step ST203, the control unit 11 is not a complicated process of extracting necessary information from a large amount of information, but only performs a simple process of repeating the same process, so the processing load is suppressed. Further, when generating each two-dimensional code, the control unit 11 reads out from the storage unit 34 information of an amount that can be converted into one two-dimensional code and stores it in the RAM 93. Therefore, the capacity of the RAM 93 is at least two-dimensional It only needs to have enough capacity to store the information to be converted into code.

In step ST205, the control unit 33 of the portable terminal 3 stores the image data received from the imaging unit 36 in the storage unit 34. At this time, the control unit 33 compares the image of the image data already stored in the storage unit 34 with the image of the image data newly received from the imaging unit 36, and if these images are different, the newly received image data It is stored in the storage unit 34. When the control unit 33 receives from the imaging unit 36 the image data of the two-dimensional code of the same image as the image of the image data already stored in the storage unit 34, the control unit 33 stops the operation of the imaging unit 36. At this time, the control unit 33 may cause the display unit 31 to display a message indicating that the information collection from the facility device 2 is completed. Thus, the control unit 33 stores a plurality of image data corresponding to a plurality of two-dimensional codes in the storage unit 34. Thereafter, the control unit 33 can acquire facility information by analyzing a plurality of two-dimensional codes.

Here, the case has been described in which the portable terminal 3 automatically stores the image data of the two-dimensional code each time the two-dimensional code displayed by the display unit 10 is sequentially switched, but the present invention is not limited to this case. When the user can recognize that the two-dimensional code displayed by the display unit 10 is sequentially switched, the user may input an imaging instruction to the portable terminal 3 each time the two-dimensional code is switched. For example, when the control unit 11 of the facility operation terminal 1 assigns serial numbers to a plurality of two-dimensional codes and causes the display unit 10 to display the two-dimensional code, the serial number of the two-dimensional code is also displayed on the display unit 10 Good.

Conventionally, if it is attempted to extract the information necessary for diagnosing an abnormality from the information indicating the operating condition etc. so that the amount of information that can be held by the two-dimensional code is less than the information amount that can be held, the algorithm for generating the two-dimensional code becomes complicated. . The program for performing information processing according to the algorithm also becomes long, and the memory capacity for storing the program also becomes large. The equipment usually has only the minimum processing capacity and memory capacity necessary to control the equipment itself. If it is attempted to execute complex algorithm processing with limited resources such as arithmetic processing devices and memories provided in the facility equipment, the load of information processing on the facility equipment becomes heavy. If a large capacity memory or the like is introduced to satisfy the arithmetic processing capability, the manufacturing cost of the equipment will increase.

On the other hand, in the second embodiment, when the facility device 2 converts the facility information into a two-dimensional code and outputs it, the portable terminal 3a acquires the facility information from the image data of the two-dimensional code, and the facility information is abnormal. The information is shaped into a notification form and transmitted to the maintenance compatible terminal 7. Therefore, resources such as the arithmetic processing device and the memory required for the facility device 2 are suppressed, and an increase in the manufacturing cost of the facility device 2 can be suppressed.

Further, in the second embodiment, even if one or both of the equipment 2 and the portable terminal 3 a do not include the short distance wireless communication unit, the portable terminal 3 a can acquire the equipment information from the equipment 2. Furthermore, when the amount of information of the facility information is large, the facility device 2 distributes the facility information into a two-dimensional code and performs information processing in units of the amount of information that can be held by the two-dimensional code. It is possible to suppress an increase in the capacity of the RAM 93.

Third Embodiment
In the first and second embodiments, the case where the portable terminal 3 transmits information necessary for diagnosing an abnormality to the maintenance compatible terminal 7 when an abnormality occurs in the facility device 2 has been described. In the third embodiment, even if there is no abnormality in the equipment 2, the portable terminal 3 collects information necessary for the maintenance of the equipment 2 so that the maintenance worker can predict the abnormality in advance. It is a thing.

Although the third embodiment will be described based on the equipment maintenance system described in the first embodiment, the third embodiment may be applied to the equipment maintenance system of the second embodiment. Moreover, since the equipment maintenance system of this Embodiment 3 is the structure similar to the equipment maintenance system demonstrated in Embodiment 1, the detailed description is abbreviate | omitted. In the third embodiment, the air conditioning operation program executed by the control unit 33 includes a state notification form in which items required for maintenance of the facility device 2 are set. In the third embodiment, the facility information includes operating condition data and a history of environmental information of the air-conditioned space. The facility information may include model information.

The operation procedure of the facility operation terminal 1 in the third embodiment will be described. FIG. 21 is a flowchart showing the operation procedure of the facility operation terminal according to the third embodiment of the present invention. When the facility device 2 starts the operation, the control unit 11 starts a timer and starts measurement of the time T (step ST301). The control unit 11 determines whether or not an abnormality has occurred (step ST302). When an abnormality occurs in the facility device 2, the control unit 11 proceeds to the process of step ST101 shown in FIG. 14 or FIG. On the other hand, when no abnormality occurs in the facility device 2, the control unit 11 determines whether the time T has elapsed until the time T1 (step ST303).

As a result of the determination in step ST303, when time T reaches time T1, the control unit 11 acquires data of the temperature and humidity of the air-conditioned space (step ST304). Subsequently, the control unit 11 updates these tables by recording the data acquired in step ST304 in the driving state data table 120 and the history data table 121 (step ST305). Thereafter, the control unit 11 resets the time T measured by the timer (step ST306), and returns to step ST302. In this way, in the state where the facility device 2 is operating normally, the operating state data and the history data are updated at a cycle of time T1.

Although not shown in FIG. 21, for example, when an instruction to change any of the start and stop of the operation, the operation mode, and the set temperature and the set humidity is input, the control unit 11 Updates the operating state data table 120 according to the input instruction. The control unit 11 notifies the control device 45 of the contents of change regarding the driving state data.

Next, the operation procedure of the equipment maintenance system of the third embodiment will be described. FIG. 22 is a sequence diagram showing an operation procedure of the facility maintenance system according to the third embodiment of the present invention. In FIG. 22, the communication connection timing between the facility operation terminal 1 and the portable terminal 3 will be described as being the same as that shown in FIG. 14, but the communication connection timing may be as shown in FIG. .

The control unit 11 of the facility operation terminal 1 determines whether or not the portable terminal 3 is in the communication range of the wireless communication 5 at regular time intervals (step ST401). When determining that the portable terminal 3 is within the communication range, the control unit 11 requests connection to the portable terminal 3 via the wireless communication 5 (step ST402). When receiving the connection request from the facility operation terminal 1, the control unit 33 of the portable terminal 3 starts the air conditioning operation program and notifies the facility operation terminal 1 of a connection permission response via the wireless communication 5 (step ST403).

When receiving the connection permission response from the portable terminal 3 via the wireless communication 5, the control unit 11 of the facility operation terminal 1 refers to the operating state data table 120 and the history data table 121 stored in the storage unit 12. Then, the control unit 11 collects equipment information including the current driving state data and the history of the environmental information of the air-conditioned space from the storage unit 12. The history of environmental information of the air-conditioned space is, for example, history data shown in FIG. Then, the control unit 11 transmits the facility information to the portable terminal 3 via the wireless communication 5 (step ST404). The facility operation terminal 1 transmits the facility information to the portable terminal 3 and consigns the extraction of the information necessary for maintenance to the portable terminal 3. Therefore, it is not necessary to sort the necessary information by itself from the facility information.

In step ST404, when receiving the equipment information from the equipment operation terminal 1, the control unit 33 of the mobile terminal 3 stores the equipment information in the storage unit 34. Then, the control unit 33 extracts information necessary for maintenance of the facility device 2, and shapes the facility information into a status notification form (step ST405). Then, the control unit 33 transmits the state notification form to the maintenance compatible terminal 7 via the network 9 (step ST406). When the maintenance support terminal 7 receives the status notification form from the portable terminal 3, the maintenance support terminal 7 stores the status notification form in the storage unit 71 (step ST407). Subsequently, the maintenance handling terminal 7 outputs a state notification form stored in the storage unit 71 (step ST408). When the maintenance compatible terminal 7 is a PC, a status notification form is displayed on the output unit 73. When the state notification form includes the operating state of the facility device 2 and the history of the environment information, the maintenance worker can determine from the information whether there is a tendency for the facility device 2 to have an abnormality.

The procedure shown in FIG. 22 is executed at timing when the facility operation terminal 1 can communicate with the portable terminal 3 when the user enters the conference room to use the conference room in which the indoor unit 50 of the facility device 2 is installed. It is conceivable. In addition, for example, when the user uses a conference room where the indoor unit 50 of the facility device 2 is installed, the facility operation terminal 1 is connected to the portable terminal 3 in the procedure shown in FIG. 17 at the timing of changing the temperature setting. The facility information may be transmitted to the portable terminal 3. Furthermore, although the case where the portable terminal 3 automatically creates a status notification form and transmits it to the maintenance-compatible terminal 7 has been described with reference to FIG. 22, the user inputs a notification instruction in the same manner as the abnormality notification form. At the timing, the portable terminal 3 may transmit the status notification form.

Moreover, in the procedure shown in FIG. 22, after storing the status notification form in the storage unit 71 in step ST407, the maintenance handling terminal 7 performs the processing in step ST408, but the present invention is not limited to this case. For example, the maintenance compatible terminal 7 sequentially stores the state notification form received from the portable terminal 3 in the storage unit 71, and outputs the state notification form stored in the storage unit 71 according to the input operation of the maintenance worker. Good. In this case, the maintenance worker can see the temporal change of the operating state of the facility device 2 by comparing and referring to the plurality of state notification forms stored by the maintenance compatible terminal 7. As a result, the maintenance worker can more easily find the parameter approaching the abnormal value from the temporal change of the operating condition and the temporal change of the environmental information.

The facility maintenance system of the third embodiment reads out information necessary for maintenance from the facility information that the portable terminal 3 receives from the facility equipment, creates a status notification form, and sends the status notification form to the maintenance compatible terminal 7 It is

In the third embodiment, by referring to the status notification form, the maintenance worker can quickly find parts and the like that are prone to failure. Therefore, even if a failure does not occur in the equipment 2, the maintenance worker can not only perform measures before failure such as failure prediction, but also can propose parts replacement to the user before the failure occurs. Further, by notifying the maintenance compatible terminal 7 of the operating state of the facility device 2 at the timing when the portable terminal 3 communicates with the facility device 2, the maintenance worker regularly goes to the location of the facility device 2 for inspection. The need is reduced.
