Description

The present invention relates to a device management system that manages a plurality of managed devices, and a search method thereof.

Conventionally, when a device to be managed is periodically or when a failure occurs, it is necessary for a worker to go to the installation location of the device to be managed and perform maintenance. Therefore, it is required to specify and manage the managed device and its installation location.

As a background technology in this technical field, there is Patent Document 1 (Japanese Unexamined Patent Publication No. 2016-386777). In this publication, in paragraph 0014, "Therefore, the management system 100 according to the present embodiment is a management target device from the position information of the terminal device received from the management target device 101 and the terminal device bundled with the management target device 101 at the time of unpacking. The information for specifying the installation location of the 101 is created. As a result, the management system 100 can create the management information of the managed device 101 without inputting the installation location by the local worker, so that the installation location can be set. The management information of the management target device 101 including the identification information becomes accurate. "

Hereinafter, various embodiments of the present invention will be described with reference to the drawings. In addition, in a plurality of drawings, those having a common number number indicate the same thing. In addition, information acquisition terminals and mobile terminals may be collectively referred to as terminals.

In the first embodiment, a plurality of managed devices, a terminal that acquires information on the managed device, assigns location information to the server, and acquires information on the managed device and the assigned location information from the terminal. A server is provided, and the server implements a device management system that manages the position information given to the information of one specific managed device existing on the device network installed at the base as the location information of the base. This is an example. Further, in the first embodiment, a plurality of managed devices, a terminal that acquires information on the managed device, assigns location information to the server, and acquires information on the managed device and the assigned location information from the terminal. This is a method of searching for a device management system that includes a server to be used, and the device management system uses the location information given to a specific managed device existing on the device network installed at the base to obtain the location information of the base. This is an example of a search method that manages as location information, searches for bases that match the set search conditions, and displays information indicating the location of the matching bases on the map based on the location information of the matching bases. ..

Hereinafter, the device management system according to the first embodiment will be described with reference to FIGS. 1 to 7. FIG. 1 is a configuration example of the device management system according to the first embodiment, and the managed device 1 is connected to the device network L1. In many cases, a plurality of managed devices 1 are connected on the device network L1, but since the operation can be explained in the same manner in that case, only one managed device 1 is shown in FIG. There is.

The managed device 1 is connected to the device network L1 at the base, and includes a first communication unit 11 which is a means of communication with the device network L1. In addition, the managed device 1 includes a storage unit 12 and a control unit 13. The storage unit 12 stores device information including the identification information of the managed device 1 and the operation log. The identification information is the serial number of the managed device 1 and the address information that can identify the managed device 1 on the device network L1. The operation log records, for example, error occurrence information of the managed device 1. The control unit 13 controls the managed device 1. For example, if the controlled device 1 is an air conditioner, the control unit 13 performs the control necessary for air conditioning.

When the communication means included in the managed device 1 is only the first communication unit 11 that communicates with the device network L1, the information can be acquired by connecting to the device network L1 as the information acquisition means of the managed device 1. In many cases, there is an information acquisition terminal 2 for the device. For example, when the managed device is an air conditioner, there is a service checker as a device corresponding to the information acquisition terminal 2. A service checker is a terminal used by a worker to acquire identification information and operation information of an air conditioner when installing and maintaining the air conditioner.

The information acquisition terminal 2 includes at least a first communication unit 21, a second communication unit 22, and a storage unit 23. The first communication unit 21 communicates with the managed device 1 via the device network L1. The second communication unit 22 communicates with the mobile terminal 3 via the second communication means L2. The second communication unit 22 and the second communication means L2 are general-purpose communication forms different from the communication form of the device network L1, and are wireless communication such as Wifi, Bluetooth (registered trademark), NFC, or a USB cable. Either wired communication may be used. At least the information acquired from the managed device 1 is stored in the storage unit 23.

If the managed device 1 is provided with a means for directly communicating with the mobile terminal 3, the information acquisition terminal 2 is unnecessary. The configuration of the device management system in that case will be described with reference to FIG. 8 according to the second embodiment.

The mobile terminal 3 is a portable information terminal such as a smartphone, a tablet, or a mobile phone. The mobile terminal 3 includes at least a first communication unit 31, a second communication unit 32, a GPS sensor unit 33, a storage unit 34, and a display unit 35. The first communication unit 31 communicates with the server 4 via the wide area network L3. The second communication unit 32 communicates with the information acquisition terminal 2 via the second communication means L2. The second communication unit 32 and the second communication means L2 may be either wireless communication such as Wifi, Bluetooth, NFC, or wired communication using a USB cable or the like, as long as they can communicate with the information acquisition terminal 2. .. The GPS sensor unit 33 receives a signal from the GPS satellite 5 and positions the position.

The storage unit 34 stores at least the address information of the server 4 and the information of the managed device 1 acquired from the information acquisition terminal 2. The display unit 35 is composed of, for example, a touch panel, and may serve as both a display device and an input device. Alternatively, a separate input device may exist. On the display unit 35, for example, a screen for instructing device information acquisition, displaying information acquisition results, instructing information transmission to the server 4, inputting work information, and the like is displayed. Further, the display unit 35 may display support information for workers such as display of the installation location of the managed device based on the information stored in the server 4.

The server 4 is a computer system having a normal configuration that plays the role of a server, and includes at least a communication unit 41, a storage unit 42, a search unit 43 realized by a functional program of a central processing unit (CPU), and a display unit 44. The communication unit 41, the storage unit 42, the search unit 43, and the display unit 44 may be divided into different devices. For example, the display unit 44 may be realized by connecting another device such as a monitor. The display unit 44 may serve as an input device as a touch panel, or may be connected to an input device. The communication unit 41 communicates with the mobile terminal 3 via the wide area network L3. The storage unit 42 stores at least the information acquired from the mobile terminal 3 and the information created in the server 4. The search unit 43 can be realized by a desired search program, and executes a search method for searching information such as a specific managed device from the information stored in the storage unit 42. The display unit 44 displays the search result of the search unit 43.

Information on the managed device 1 is acquired at the timing of installation or maintenance of the managed device 1. A sequence from the worker acquiring the information of the managed device 1 to registering it in the server 4 will be described with reference to FIG.

The worker connects the information acquisition terminal 2 to the device network L1 to which the managed device 1 is connected at the installation base of the managed device 1. Next, the mobile terminal 3 brought by the worker is connected to the information acquisition terminal 2 via the second communication means L2. When the worker performs an information acquisition operation on the mobile terminal 3 (S100), the mobile terminal 3 issues a device information acquisition instruction to the information acquisition terminal 2 (S101). The information acquisition terminal 2 requests device information from the managed device 1 (S102). The managed device 1 transmits device information such as identification information and an operation log stored in its own storage unit 31 to the information acquisition terminal 2 (S103). The information acquisition terminal 2 transmits the received device information to the mobile terminal 3 (S104). At that time, the GPS sensor unit 33 of the mobile terminal 3 receives a signal from the GPS satellite 5 (S105) and positions the mobile terminal 3. After associating the acquired device information with the position information, it is stored in the storage unit 34 of the mobile terminal 3. The worker inputs work information such as a base name and a worker into the mobile terminal 3 (S106). The input work information is stored in the storage unit 34 of the mobile terminal 3 in association with the acquired device information and position information.

Next, the worker issues an instruction to transmit the information to the server 4 to the mobile terminal 3 (S107). The mobile terminal 3 transmits the device information, the position information, and the work information acquired in the storage unit 34 to the server 4 (S108). The storage unit 42 of the server 4 is provided with an information storage form such as a database, and the server 4 registers the received information in the database of the storage unit 42 (S109).

The work information input (S106) to the mobile terminal 3 may be performed before the device information acquisition instruction (S100). Further, although the GPS signal is periodically transmitted from the GPS satellite 5, only the GPS signal at the timing when the position needs to be determined is specified as S105.

When a plurality of managed devices are connected to the device network L1, for example, S101 to S106 are repeated to acquire all necessary device information of the managed devices in the mobile terminal 3 and store them in the storage unit 34. Alternatively, after repeating S102 and S103 to acquire and store information on a plurality of managed devices in the storage unit 23 of the information acquisition terminal 2, all the device information of the storage unit 23 of the information acquisition terminal 2 is stored in the mobile terminal in S104. It may be transmitted to 3. In that case, there is an advantage that the number of operations by the worker on the mobile terminal 3 and the number of communications between the mobile terminal 3 and the information terminal 2 are reduced.

The mobile terminal 3 may be able to specify which information of the managed device 1 is required. Alternatively, the information of all managed devices on the device network L1 may be automatically acquired. In that case, when storing in the server 4, it may be compared with the information registered in the database of the server 4, only the difference information is registered in the database, and unnecessary information may be discarded. For example, if there is a possibility that a new managed device has been newly installed after the previous work, the device information that has already been registered is automatically detected and discarded, and only the new managed device is registered. May be good.

As described above, even when a plurality of managed devices exist, information can be acquired and managed by one mobile terminal 3 and an information acquisition terminal 2.

From here, an example of a device management system in the case where the controlled device 1 is an outdoor unit or an indoor unit of an air conditioner will be described with reference to FIG. It is assumed that outdoor units 6a and 6b and indoor units 7a and 7b are installed in the base. The outdoor unit 6a and the indoor unit 7a are connected by a refrigerant pipe L4a to form one refrigeration cycle. Similarly, the outdoor unit 6b and the indoor unit 7b are connected by a refrigerant pipe L4b to form one refrigeration cycle. In this case, the outdoor unit 6a and the indoor unit 7a belong to the same refrigerant system. Further, the outdoor unit 6b and the indoor unit 7b belong to the same refrigerant system.

These outdoor units 6a and 6b and indoor units 7a and 7b are connected by an air conditioning network L1a. The air-conditioning network L1a corresponds to the device network L1 of FIG. 1, and is used for communication when a plurality of outdoor units / indoor units cooperate to perform air conditioning. Since it is necessary to identify the refrigerant systems in the air conditioning network L1a, numbers that do not overlap on the same air conditioning network are assigned to each refrigerant system. In addition, the outdoor unit and indoor unit are assigned the numbers of units that do not overlap in the same refrigerant system. This number is generally assigned from the youngest number automatically.

At this time, if the air conditioning network is the same, the desired outdoor unit or indoor unit can be specified by the combination of the refrigerant system and the unit. For example, the outdoor unit 6a and the indoor unit 7a are set to 0 system, the outdoor unit 6a is set to 0 unit, the indoor unit 7a is set to 1 unit, the outdoor unit 6b and the indoor unit 7b are set to 1 system, the outdoor unit 6b is set to 0 unit, and the indoor unit 7b is set. Is the first machine. In this case, the outdoor unit 6a can be designated on the air conditioning network L1a by the information of 0 system 0 unit.

In this case, the "address information that can identify the managed device 1 on the device network L1" described in the description of FIG. 1 corresponds to the combination of the refrigerant system and the unit. Therefore, the identification information of the management target device 1 stored in the storage unit 12 of the management target device 1 includes the address information including the information of the refrigerant system and the unit. The information acquisition terminal 2 corresponds to a service checker here. Since the other elements in FIG. 3 are the same as those in FIG. 1, the description thereof will be omitted.

Here, an example of a database included in the storage unit 42 of the server 4 will be described with reference to FIG. The database of the server 4 includes the device management table D1, the work management table D2, and the error management table D3 shown in (a), (b), and (c) of the figure. The device management table D1 includes a base name, a base number, a base position information, a refrigerant system, a unit, a serial number, an area name, a device name, and a position information. The refrigerant system, unit, and serial number correspond to the identification information acquired from the controlled device 1. The base name, area name, and device name are information input by the worker to the mobile terminal 3, and are included in the work information input in S105 of FIG. The area name is information used by a worker to specify a specific location of the device in the base, such as floor information in which the managed device 1 is installed. The device name is a name for workers to distinguish the device for convenience. The area name and device name are not required and do not have to be entered. The position information is the position information acquired by the GPS sensor 33 of the mobile terminal 3.

In the configuration of this embodiment, the refrigerant system, serial number, area name, device name, and position information are registered as unique information for each managed device. On the other hand, the base name, base number, and base location information are unique information for each base, and the same information is registered for all managed devices of the same base. The base name is a name that identifies the base, such as the building name of the installation base. Similar to the area name and the device name, the information is input by the worker to the mobile terminal 3, and is included in the work information input in S106.

There may be multiple managed devices at the site, and each may have different location information. When searching for the location of a base from a database or displaying the location of a base on a map based on the information in the database, it is difficult to handle if there are multiple location information at the base. Therefore, it is desirable to determine one unique location information for each base. Therefore, in this embodiment, the base location information is set as the only information indicating the location of the base. In the base location information, the location information of the managed device 1 having a combination of the youngest refrigerant system in the base and the unit number is set. Specifically, the position information of the managed device 1 which is the 0 system and the 0th machine is used. Since the system and the unit are set in order from the youngest number, there is a characteristic that there is always one device of the 0 system and the 0 unit at every base.

Since the base name is entered by the worker, an input error may occur. Therefore, as a mechanism for enabling name identification, in this embodiment, a base number is set for each base based on a unique number based on the device information of the base. In the base number, the serial number of the managed device 1 having a combination of the youngest refrigerant system in the base and the number of the unit is registered. Specifically, it refers to the serial number of the managed device 1 which is the 0 system and the 0th machine. For example, when registering information in the database in S109 of FIG. 2 on the server 4 using the base number, it is possible to prevent multiple registration of bases due to an input error of the base name.

This will be described in more detail with reference to the flowchart shown in FIG. When the worker transmits the information of the managed device 1 from the mobile terminal 3 to the server 4, the server 4 extracts the serial number of the device of the 0 system and the 0th machine from the received information, and the same number as the extracted serial number. Searches whether it exists in the device management table as the base number (S201). If the serial number of the equipment of system 0 and Unit 0 does not yet exist as the base number in the equipment management table, it is judged that it is the base where the work was done for the first time, and the serial number of the equipment of system 0 and Unit 0 is the installation base of the equipment. The base number and location information of are registered in the device management table as the base location information (S202).

If the serial number of the equipment of system 0 and Unit 0 already exists as the base number in the equipment management table, it is determined that the base has worked in the past. In that case, it is confirmed whether the base name having the same base number matches the base name as the information currently received by the server 4 (S203). If they match, it is determined that there is no input error in the base name, and all device information, location information, and work information received by the server 4 are registered in the device management table, work management table, error management table, etc. ( S204). If they do not match, check whether the base name has been entered incorrectly (S205). The confirmation may be performed by any means, but for example, a notification is sent to the mobile terminal 3 when there is a suspicion of an input error. The worker sees the notification and confirms whether it is a typo. If there is an input error, the worker re-enters the correct base name on the mobile terminal 3 or the like (S206). After that, S203 is re-executed to reconfirm the base name, and if there is no problem, the device information is registered (S204).

If it is determined in S205 that the worker does not make an input error, the information of the base is newly registered (S202, S204). For example, if the base is the same but the building name or customer name changes, it is not a typo, so a new base name is registered. At this time, the base name may be overwritten and registered, but it is inconvenient if the past base name is unknown, so it is desirable to be able to retain the past base name as well. Information with the same base number but different base names may be registered in the device management table D1. In that case, since the base numbers are the same, it is possible to consider the same base by identifying the bases by the base number. Is. Alternatively, an item for storing information such as a past base name may be prepared in the device management table.

The base name, base number, and base location information may be divided and saved in a table different from the device management table D1. For example, there may be a separate base management table that includes the base name, base number, and base location information.

The work information management table D2 includes a serial number, a work date and time, a worker, and operation information. As described above, the serial number is the serial number provided in the managed device, and is recorded as information for identifying the device in which the work is performed. As long as the information can identify the device, the combination information of the base name, the refrigerant system, and the unit may be used instead of the serial number. The work date and time is the date and time when the information acquisition work is performed, and the date and time information in the mobile terminal 3 may be automatically recorded and added to the work information transmitted from the mobile terminal 3 to the server 4. Alternatively, the worker may input by himself / herself in S106. The worker is the information that the worker has entered his / her name in S106. The worker may be automatically identified by using the identification information of the mobile terminal 3 and the name may be input.

The operation information is the operation information of the managed device 1 acquired by the information acquisition terminal 2. The air conditioner shall be commissioned during installation, maintenance, and operation. At that time, detailed driving information can be acquired in the service checker corresponding to the information acquisition terminal 2, and the information acquired at that time is registered. Since the amount is enormous, it may be divided and recorded in another table. Alternatively, the information registered in the operation information may be an operation log stored in the storage unit 12 of the managed device 1. The operation log is a log that mainly records abnormal operations such as alarm occurrence status, maintenance operation, and number of operation retries. The operation log may be recorded in the error management table D3, and the association information for indicating which error information in the error management table D3 is acquired at which work may be recorded instead.

The error management table D3 includes the serial number, the date and time of occurrence, and the error type. The serial number is the serial number of the managed device as described above, and is recorded as information for identifying the device in which the work is performed. As long as the information can identify the device, the combination information of the base name, the refrigerant system, and the unit may be used instead of the serial number. The date and time of occurrence is the date and time when the abnormal operation occurred. The error type is the type of abnormal operation that occurred. For example, the type of alarm and maintenance operation. It is created based on the operation log information and the like stored in the storage unit 12 of the managed device 1.

Next, using FIG. 6, the database provided in the storage unit 42 of the server 4 is searched by the search unit 43 under specific conditions, so that a specific managed device is selected from among a large number of managed devices. A search method for identifying and displaying information on the display unit 44 in an easy-to-understand manner will be described. The figure is an example of the search screen 600 of the managed device displayed on the display unit 44 of the server 4. On this screen, it is possible to search for managed devices that require maintenance based on operation log information, and to search for desired managed devices by base name.

The search screen 600 includes three display areas: a search condition area 601, a map display area 602, and a device information display area 603. The search condition area 601 includes a search condition input field and a search execution button. In the search condition input field, for example, the number of errors, error type, number of maintenance operations, cumulative operation time, number of retries, base name, location information, etc. are displayed as search conditions. If a large number of search conditions cannot be displayed, for example, the search condition area 601 may be expanded by pressing the icon displayed at the lower right of the search condition area 601. Alternatively, the screen may transition to another screen displaying detailed search conditions.

When the search execution button in the upper right part of the search condition area 601 is pressed, the search unit 43 of the server 4 searches the database of the storage unit 42, and displays the search results in the map display area 602 and the device information display area 603. If a large number of devices satisfy the search conditions and the list information of the devices is displayed in the map display area 602 or the device information display area 603, a large number of information is displayed on the screen and is difficult to see. Therefore, it is easier to see by displaying the information for each base.

In the map display area 602, information indicating the location of the base is displayed on the map based on the base position information of the base corresponding to the search result. As information indicating the location of the base, for example, the base icons 604a and 604b indicating the base name are displayed. Although the building name is displayed as the base name on the base icons 604a and 604b, the building name may not be displayed and the icon form may be different. In the device information display area 603, the bases corresponding to the search results are displayed in a list. Note that the three display areas may be divided and displayed on different screens instead of being displayed on the same screen as shown in FIG.

FIG. 7 is an example of the device list screen 605 that displays a list of managed devices on the display unit 44 of the server 4 of this embodiment. When a desired base is selected by clicking the base icons 604a and 604b in the map display area 602 or clicking the base name in the device information display area 603, a list of managed devices installed at that base is displayed on the device list screen. It is displayed at 605. On the device list screen 605, for example, the contents of the device management table having the base number corresponding to the selected base are displayed. The device list screen 605 may be displayed in the device information display area 603 of the search screen 600, or may be displayed on a separate screen.

It is desirable that the list of device information on the device list screen 605 is arranged and displayed for each refrigerant system. Only the number of the refrigerant system existing in the selected base is displayed first, and by selecting the refrigerant system by clicking the number of the refrigerant system, a list of managed devices belonging to the refrigerant system is further displayed. You may do so. A list of devices may be displayed in advance arranged by the system number of the refrigerant system and the number of the unit.

As shown in FIG. 7, when displaying a list of managed devices on the device list screen 605, for example, a column indicating whether or not the search condition is applicable is displayed, and marks are displayed in the column of the device corresponding to the search condition. By doing so, only the applicable equipment can be distinguished. The display of the corresponding device may be made distinguishable by making it in red or bold. As a result, it is possible to easily find a desired device that meets the search conditions from the list of devices.

Alternatively, only the list of devices that meet the search conditions may be displayed on the device list screen 605 from the beginning. It may be possible to switch whether to display only the devices corresponding to the search conditions on the device list screen 605 or to display all the devices in the base. For the switching, for example, the display method of the search result may be selected by the search condition, or the device list display setting may be changed by providing a separate display setting screen.

Since the number of devices is large, it is necessary to scroll the screen to check all the devices. For example, a scroll bar may be displayed on the right side of the device list screen 605 to enable scrolling. If the display screen is a touch panel or the like, the screen may be scrolled by scrolling the screen with a finger without displaying the scroll bar.

If you select a desired device while the list of devices is displayed, detailed information about that device is displayed. For example, each device on the device list screen 605 has a field for selecting a detailed display, and FIG. 7 has a detail field on the left side of the scroll bar. By selecting a character such as "display" in the field, the details of the managed device are provided. Display information. Alternatively, the detailed information display screen of the device may be displayed by selecting a character in any column of the corresponding device, such as the device name of the corresponding device on the device list screen 605.

On the detailed information display screen of the device, for example, the information of the work information management table D2 and the error management table D3 corresponding to the serial number of the selected managed device is displayed. That is, the operation information acquired during maintenance work, the acquisition date and time, the error type, and the date and time of occurrence are displayed. The information may be displayed in tabular format or in graph format. The detailed information of the device may be displayed in the device information display area 603, or may be displayed by transitioning to another screen for displaying the detailed information.

An example of the operation and transition of the search screen 600 will be described with reference to FIGS. 6 and 7. For example, when a search is performed by inputting an error of 5 times or more in the search condition input field of the search condition area 601 of FIG. 6, the search unit 43 of the server 4 identifies the device corresponding to the condition. It is assumed that there are multiple devices in which the error has occurred 5 times or more, and the bases that have these devices are the XX building and the XX building. The location information of each base is displayed as an icon in the map display area 602, and a list of base names is displayed in the device information display area 603. Next, when the base icon 604a of the XX building in the map display area 602 is clicked, the device list screen 605 as shown in FIG. 7 is displayed in the device information display area 603 as list information of the devices corresponding to the XX building. Will be done.

As shown in the figure, the devices in which the error occurs five times or more are the three devices with serial numbers AAA, BBB, and EEE, and a check mark is displayed in the corresponding column of each device. If you select the display of the detail column of the device with serial number AAA, the screen transitions to the screen where detailed information such as error information of the device with serial number AAA is displayed. As a result, the managed devices that meet the search conditions can be easily identified and browsed using the information of the installation base. The operations and transitions described are examples, and they actually have multiple variations described so far.

The search screen 600 and the device list screen 605 showing the result may be displayed on the display unit 35 of the mobile terminal 3. For example, the search condition is input by the mobile terminal 3, the search unit 43 of the server 4 searches the database of the storage unit 42, and the result is acquired and displayed on the mobile terminal 3. As a result, when the worker goes to the installation base, the information on the managed device and the installation base can be searched, and the work of the worker can be supported.

According to the device management system and the search method according to the first embodiment described in detail above, it is possible to acquire, manage, and search the location information of the managed device and the base at low cost.

The second embodiment is an embodiment of the device management system when the managed device includes means for directly communicating with the mobile terminal. When the managed device 1 has a plurality of communication means, the mobile terminal 3 can directly communicate with the managed device 1 and acquire information. In this embodiment, the device management system does not require the information acquisition terminal 2.

A configuration example of the device management system according to the second embodiment will be described with reference to FIG. As shown in the figure, the managed device 1 includes at least the first communication unit 11, the storage unit 12, the control unit 13, and the second communication unit 14. The first communication unit 11 communicates with a managed device in another base via the device network L1. In FIG. 8, the notation of the device network L1 and other managed devices is omitted. The second communication unit 14 communicates with the mobile terminal 3 via the general-purpose second communication means L2. The second communication means L2 is preferably short-range wireless communication such as NFC. However, other wireless communication such as Bluetooth and Wifi, and wired communication such as USB may be used.

The mobile terminal 3 includes a first communication unit 31, a second communication unit 32, a GPS sensor unit 33, a storage unit 34, and a display unit 35. The first communication unit 31 communicates with the server 4 via the wide area network L3. The second communication unit 32 communicates with the managed device 2 via the second communication means L2. Since the other parts of FIG. 8 are the same as those of the first embodiment, the description thereof will be omitted.

When the second communication means L2 is short-range wireless communication such as NFC, the worker holds the mobile terminal 3 directly over the management target device 1 for which information is to be acquired, so that the information in the storage unit 12 of the management target device 1 can be stored. You can get it. Since the information registration and screen display contents on the server 4 after the information is acquired in the mobile terminal 3 are the same as those in the first embodiment, the description thereof will be omitted.

Compared with Example 1, the system of this example has the following advantages. In the first embodiment, since the mobile terminal 3 is connected to the information acquisition device 2, the position information acquired by the GPS sensor unit 43 of the mobile terminal 3 becomes the information on the installation position of the information acquisition device 2, and the management target device 1 is installed. There is a deviation from the position information of the position. On the other hand, in this embodiment, since the mobile terminal 3 is brought close to each managed device 1 to acquire information and the position information is acquired at that time, the position information that substantially matches the installation position of the managed device 1 is acquired. It is possible to manage. As a result, the installation position of the management target device 1 can be specified in detail, so that it can be used as information for the worker to search for the installation position of the management target device 1 in the base at the subsequent maintenance opportunity. ..

Further, in the first embodiment, even if the position of the managed device 1 to be maintained can be specified, for example, if the managed device 1 is an air conditioner, the information must be specified via the air conditioning network L1 unless the refrigerant system and the unit are specified. Cannot be obtained. Since it is often the case that the refrigerant system and unit cannot be identified by looking at the exterior of the outdoor unit or indoor unit, it is necessary to identify the refrigerant system and unit by actually operating some outdoor units and indoor units. On the other hand, in the second embodiment, since the information is acquired without going through the air conditioning network L1, there is a peculiar effect that the device information can be acquired even when the information of the refrigerant system and the unit is unknown.

The present invention is not limited to the above-described examples, and includes various modifications. For example, the above-mentioned examples have been described in detail for a better understanding of the present invention, and are not necessarily limited to those having all the configurations of the description.

Further, each of the above-mentioned configurations, functions, servers, etc. has been described mainly with an example of creating a program that realizes a part or all of them, but it is hard to design a part or all of them by, for example, an integrated circuit. Needless to say, it can be realized with hardware. That is, all or part of the functions of the processing unit may be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array) instead of the program.
