Description

  The present invention relates to an equipment operation terminal for monitoring and operating equipment installed in a building or the like, and a related technology.

  Equipment operation terminals that monitor and operate equipment such as air conditioners and lighting equipment installed in the building can be provided at a low price with low manufacturing costs. In many cases, only necessary functions are provided. For this reason, a communication interface (for example, a USB (Universal Serial Bus) terminal, a LAN (Local Area Network) adapter, etc.) for outputting data held therein to an external device or the like is generally not provided.

  This kind of equipment operation terminal is usually provided with a display device such as a liquid crystal display, and the user can check the operation state of the equipment via a liquid crystal screen or the like. However, since the data cannot be output to an external device as described above, when attempting to electronically record and manage data related to the operating state of the equipment and abnormality history, the user can visually check the data via a liquid crystal screen or the like. There have been operations such as copying the contents once by hand on a paper medium such as a notebook or inputting the display contents directly into a portable information terminal or the like at the site.

  For example, Patent Document 1 discloses a technique (remote failure diagnosis system) that is intended to transmit device information in the event of a failure of a facility device in detail and easily to a repairer who is not on site. In this remote fault diagnosis system, equipment such as an air conditioner has a function of converting equipment information (error code, sensor value information, control value information, etc.) into a two-dimensional bar code and displaying it when an abnormality occurs. ing. The user captures the displayed two-dimensional barcode using a mobile phone with a digital camera or the like, and transmits the photographed two-dimensional barcode to the diagnostic server. Then, the diagnosis server decodes the device information from the two-dimensional bar code, thereby performing a failure diagnosis of the equipment.

JP 2004-265317 A

  In the technique proposed in Patent Document 1, the device information is converted into one two-dimensional barcode, so the amount of information is naturally limited. That is, for example, assuming that the size of the liquid crystal screen or the like provided in the equipment is about 160 × 160 dots, 2 modules of 2 liquid crystals are used as one module so that the mobile phone can be reliably read. When a dimensional barcode is created, only an information amount of about 600 bytes for alphanumeric characters and about 400 bytes for binary characters can be stored.

  The above problem can be solved by increasing the size of a liquid crystal screen or the like for displaying a two-dimensional barcode, but the cost increases and it cannot be said that it is practical.

  The present invention has been made to solve the above-mentioned problems of the prior art, and even if an interface for outputting data to the outside is not provided, a large amount of data held therein can be stored in an external device. It aims at providing the equipment operation terminal etc. which enabled it to transmit to.

In order to achieve the above object, the facility operation terminal according to the present invention is:
A facility operation terminal that is connected to one or a plurality of facility devices so that data communication is possible,
Equipment data storage means for storing equipment data related to the equipment acquired from the equipment;
Upon receiving a data output request, two-dimensional code generation that reads out the equipment data to be output from the equipment data storage means as output data and generates a two-dimensional code in a predetermined format expressing the content of the read output data Means,
Two-dimensional code display means for displaying the two-dimensional code generated by the two-dimensional code generation means,
When the size of the output data exceeds a preset data size threshold, the two-dimensional code generation means divides the output data into a plurality of data, and a plurality of data is provided so as to correspond to the divided data. Generate a two-dimensional code,
The two-dimensional code display means is characterized in that, when the plurality of two-dimensional codes are generated by the two-dimensional code generation means, each two-dimensional code is sequentially switched and displayed every predetermined time.

  According to the present invention, when the size of the data to be output is large, the facility operation terminal divides the data into a plurality of data, and generates and displays a two-dimensional code corresponding to each divided data. Even if an output interface is not provided, a large amount of data can be transmitted to an external device such as an information processing terminal.

  The input unit 32 includes operation buttons provided on the equipment operation terminal 3, a touch panel, a mouse, a keyboard, and the like, and performs a process of receiving an operation input from a user. For example, when a touch panel is employed, a transparent flat plate capacitive sensor that detects a change in capacitance is mounted on the liquid crystal display. When this capacitive sensor detects contact (press) on the touch surface (for the user, the display screen of the liquid crystal display) with the user's fingertip or a dedicated pen, the position information (coordinate data) is controlled. Is output to the unit 34. The control unit 34 determines the operation content of the user based on the position information.

  The data storage unit 33 plays a role as a so-called secondary storage device (auxiliary storage device), and includes, for example, a readable and writable nonvolatile semiconductor memory such as a flash memory. The data storage unit 33 stores various data (equipment device data) necessary for the control unit 34 to control each facility device 2. As shown in FIG. 2, the data storage unit 33 stores an operation state data table 330 and a history data table 331 when roughly classified.

  The operation state data table 330 stores information on the current operation state for each equipment device 2. For example, setting information such as operation / stop information, operation mode, setting temperature, temperature (room temperature and temperature inside each device), information on sensor detection values such as pressure value, power consumption, CO2 concentration (sensor information), Information on abnormal states such as the presence / absence of an abnormality and an abnormal code (abnormal state information), information on an energy saving operation state such as a capacity saving amount, and the like are stored.

  The history data table 331 stores trend data obtained by extracting operation histories, operation histories, abnormality histories, sensor detection values, and the like of each equipment device 2 at regular time intervals.

Functionally, the control unit 34 includes an equipment device management unit 340, a two-dimensional code generation unit 341, and a two-dimensional code display control unit 342 as shown in FIG. Each of these functional units is realized by the CPU executing a program stored in a ROM or the like.

  The facility device management unit 340 outputs data (operation state data) regarding the operation state acquired from each facility device 2 via the dedicated communication line 5 to the display unit 31 and stores it in the data storage unit 33. Further, the facility device management unit 340 generates operation control data based on an operation instruction for the facility device 2 input by the user via the input unit 32, and sends the specified facility device 2 via the dedicated communication line 5. To send. The equipment 2 that has received the operation control data performs an operation according to the contents.

  The two-dimensional code generation unit 341 generates a two-dimensional code 6 (see FIG. 1) that represents the specified data content when a data output command is input through the input unit 32 by the user. In the present embodiment, the two-dimensional code 6 is a so-called matrix type two-dimensional code. Although the details will be described later, the two-dimensional code generation unit 341 divides the data to be output when the size of the data to be output exceeds a preset maximum size that can be expressed by one two-dimensional code 6. Then, a plurality of two-dimensional codes 6 are generated.

  The two-dimensional code display control unit 342 causes the display unit 31 to display the two-dimensional code 6 generated by the two-dimensional code generation unit 341. When there are a plurality of generated two-dimensional codes 6, the two-dimensional code display control unit 342 sequentially switches each two-dimensional code 6 at a predetermined time interval and causes the display unit 31 to display the two-dimensional code 6.

  The information processing terminal 4 is a portable device such as a mobile phone or a PDA (Personal Digital Assistant) and has a function of reading the two-dimensional code 6 (two-dimensional code reader function).

  As illustrated in FIG. 4, the information processing terminal 4 includes a control unit 40, a communication unit 41, a data storage unit 42, a display unit 43, an input unit 44, and an imaging unit 45.

  The communication unit 41 includes an antenna 410 and the like, and transmits / receives data to / from other information processing terminals, information processing apparatuses, and the like using a predetermined communication method in a mobile phone or the like under the control of the control unit 40.

  The data storage unit 42 plays a role as a so-called secondary storage device (auxiliary storage device), and includes, for example, a readable and writable nonvolatile semiconductor memory such as a flash memory. The data storage unit 42 stores various programs including a two-dimensional code processing program. For example, if the information processing terminal 4 of this embodiment is a mobile phone, an application program that can be executed on a mobile phone that is created in accordance with a standard such as an i-appli or EZ app is stored in the data storage unit 42. The The data storage unit 42 also stores image data obtained by photographing by the imaging unit 45 as necessary.

  The display unit 43 is configured by a liquid crystal display or the like, and displays a screen for user operation or displays user input results, user-desired data, and the like under the control of the control unit 40.

  The input unit 44 includes a keypad, a touch pad, and the like, receives an input from the user, and outputs a signal related to the received input content to the control unit 40.

  The imaging unit 45 includes a CMOS image sensor, a lens unit, and the like, captures moving images and still images, and stores image data obtained as a result of imaging in the data storage unit 42 and the like.

  The control unit 40 includes a CPU, a ROM, a RAM, and the like (all not shown), and controls the information processing terminal 4 as a whole. Functionally, the control unit 40 includes a two-dimensional code reading unit 400, a read data storage unit 401, and a read data display control unit 402, as shown in FIG. Each of these functional units is realized by the CPU of the control unit 40 executing a two-dimensional code processing program stored in the data storage unit 42.

  The two-dimensional code reading unit 400 reads the two-dimensional code 6 displayed on the display unit 31 of the equipment operation terminal 3, decodes the read two-dimensional code 6, converts it to a predetermined data format, and converts the converted data The read data is supplied to the read data storage unit 401 as read data. Here, when a plurality of two-dimensional codes 6 are generated and displayed from one output data at the equipment operation terminal 3, the two-dimensional code reading unit 400 reads the plurality of two-dimensional codes 6 after reading them. Then, the divided data are combined and restored to one data. Then, the restored data is converted into a predetermined data format, and the converted data is supplied to the read data storage unit 401 as read data.

  The read data storage unit 401 stores the read data supplied from the two-dimensional code reading unit 400 in a predetermined memory. At this time, the read data storage unit 401 may store the supplied read data in a RAM that is a volatile memory so that it can be displayed immediately, or a non-volatile memory so that it can be used even after restarting. The data may be stored in the data storage unit 42.

  The read data display control unit 402 reads the read data stored in the data storage unit 42 and the like by the read data storage unit 401 and displays the read data on the liquid crystal screen of the display unit 43 in a predetermined manner. At this time, the original two-dimensional code 6 may be converted and displayed, or may be displayed as a graph or synthesized with a predetermined plan view.

  In the equipment management system 1 configured as described above, an operation for transmitting output data from the equipment operation terminal 3 to the information processing terminal 4 will be described.

  First, the operation of the equipment operation terminal 3 will be described. When the power of the facility operation terminal 3 is turned on, the facility device management unit 340 performs initial communication with each facility device 2, performs notification setting when the state of the facility device 2 changes, scheduled communication processing setting, etc. The operation state of each facility device 2 can be managed on the facility operation terminal 3. The latest data of each facility device 2 is stored in the operation state data table 330 of the data storage unit 33 at the timing when the state change notification is received or when the state of the facility device 2 is collected at regular intervals.

  In addition, when an abnormality occurs in the equipment device 2, data indicating the abnormality is stored in the history data table 331 at the timing when the abnormality notification is received from the equipment device 2. In addition, when storing periodic trend data, the operation state data is read from the operation state data table 330 of the data storage unit 33 at regular time intervals, and the contents are processed into a predetermined format under predetermined conditions. Thereafter, it is stored in the history data table 331.

  FIG. 6 shows an example of the operation state data table 330. Here, the operation mode of each equipment 2 and the detection value of each sensor are stored. FIG. 7 shows an example of the history data table 331, (a) shows an example in which an abnormality history is stored, and (b) shows an example in which temperature trend data is stored.

  In the examples of FIGS. 6 and 7, the headings for each item are attached and described in text character strings, but these data are converted into binary data and compressed and displayed in a normal text editor. It may be stored in a format that cannot.

  Next, a two-dimensional code generation process executed by the control unit 34 (two-dimensional code generation unit 341) of the equipment operation terminal 3 will be described with reference to FIG. In the following processing, the two-dimensional code generation logic itself conforms to the conventions of the two-dimensional code adopted, and here, the description will focus on the features of the present invention.

  When an operation for requesting data output is performed by the user via the input unit 32 (step S101; YES), the two-dimensional code generation unit 341 accesses the data storage unit 33 to access the driving state data table 330 or the history. The designated data (output data) is acquired from the data table 331 (step S102). Here, the user designates, via the input unit 32, the type of data desired to be output (whether it is operating state data or history data), the period (one day, one week, one month, etc.), etc. can do.

  Next, the two-dimensional code generation unit 341 determines whether the size of the acquired output data exceeds a predetermined data size threshold (step S103). In the present embodiment, it is assumed that a data size corresponding to the maximum two-dimensional code that can be displayed in the two-dimensional code display area of the display unit 31 is set in advance as the data size threshold.

  As a result of the determination, if the size of the output data is equal to or smaller than the data size threshold (step S103; NO), the two-dimensional code generation unit 341 corresponds to the output data, that is, a matrix format that expresses all of the contents. The two-dimensional code 6 is generated (step S104), and this process is terminated.

  On the other hand, when the size of the output data exceeds the data size threshold (step S103; YES), the two-dimensional code generation unit 341 divides the output data into a plurality of data (step S105). For example, the two-dimensional code generation unit 341 divides the output data into a plurality of data by sequentially cutting out data corresponding to the threshold value from the top of the output data.

  Then, the two-dimensional code generation unit 341 generates a two-dimensional code corresponding to each of the divided data (step S106), and ends this process. Here, it is assumed that the two-dimensional code corresponding to the divided data stores information indicating the number of divisions and the division number.

  Next, a two-dimensional code display process executed by the control unit 34 (two-dimensional code display control unit 342) of the equipment operation terminal 3 will be described with reference to FIGS. The two-dimensional code display process is executed following the above-described two-dimensional code generation process.

  The two-dimensional code display control unit 342 first determines whether the number of the two-dimensional codes 6 generated by the two-dimensional code generation unit 341 is plural. As a result, when the generated two-dimensional code 6 is one, the two-dimensional code 6 is displayed continuously (that is, continuously) in the two-dimensional code display area of the display unit 31. On the other hand, when the generated two-dimensional code 6 is plural, the two-dimensional code display control unit 342 sequentially switches and displays each two-dimensional code 6 at regular time intervals.

  FIG. 9 shows an example when the two-dimensional code 6 is displayed in the two-dimensional code display area of the display unit 31. As shown in FIG. 9, when the generated two-dimensional code is one, the same two-dimensional code 6 is displayed continuously, and when divided into three, the three two-dimensional codes 6a to 6c are sequentially switched and displayed. In the case of six divisions, six two-dimensional codes 6a to 6f are sequentially switched and displayed.

  FIG. 10 is an example of a timing chart when three generated two-dimensional codes are sequentially switched and displayed. As shown in FIG. 10, the two-dimensional code display control unit 342 switches the display to the two-dimensional code 6B after displaying the two-dimensional code 6A for a certain period of time, and then switches to the two-dimensional code 6C after a certain period of time has elapsed. Execute repeatedly.

  When the two-dimensional code display control unit 342 displays the two-dimensional code 6 as described above for a predetermined time (for example, 2 to 3 minutes), the two-dimensional code display processing ends. In addition, when the operation indicating the display end request is performed by the user, the two-dimensional code display process may be immediately ended.

  Next, the two-dimensional code handling process executed by the information processing terminal 4 will be described with reference to FIG. The two-dimensional code corresponding process is started when a predetermined operation is performed by the user via the input unit 44. For example, the user can start the processing corresponding to the two-dimensional code by selecting an icon indicating the start of the program for two-dimensional code processing on the operation menu screen displayed on the liquid crystal screen or the like of the display unit 43. .

  When the two-dimensional code processing program is activated and the two-dimensional code correspondence processing is started, the control unit 40 causes the display unit 43 to display a mode selection screen (such as a menu screen) (step S201). The user can select a desired processing mode via this mode selection screen. In the present embodiment, three processing modes are prepared: a reading mode, a display mode, and an end mode.

  When any processing mode is selected by the user's touch operation or the like (step S202; YES), the control unit 40 determines which processing mode is selected (step S203). As a result, when the reading mode is selected by the user (step S203; reading mode), the two-dimensional code reading unit 400 reads the two-dimensional code 6 displayed on the facility operation terminal 3 (step S204). More specifically, the two-dimensional code reading unit 400 controls the imaging unit 45 to photograph the two-dimensional code displayed on the equipment operation terminal 3 and obtain the captured image, thereby displaying the displayed two-dimensional code. To get.

  The two-dimensional code reading unit 400 analyzes the read two-dimensional code 6, and determines whether or not the read two-dimensional code 6 is divided (step S205). Whether it is divided or not can be determined from information indicating the number of divisions embedded in the two-dimensional code 6.

  As a result, when the read two-dimensional code 6 is not divided (step S205; NO), the two-dimensional code reading unit 400 converts the read two-dimensional code 6 into a predetermined data format, and reads the read data. Is supplied to the read data storage unit 401. The read data storage unit 401 stores the supplied read data in the data storage unit 42 or the like (step S206). Then, the control unit 40 sets the reading mode to a non-selected state (in other words, shifts the processing mode from the reading mode to neutral), and performs the process of step S201 again.

  On the other hand, when the read two-dimensional code 6 is a part of the divided one (step S205; YES), the two-dimensional code reading unit 400 reads all the remaining two-dimensional codes 6 (step S207). . For example, when the number of divisions is six and the division number embedded in the two-dimensional code 6 read first is “1”, the two-dimensional code 6 having division numbers “2” to “6” is read. Do.

  When all the divided two-dimensional codes 6 are read, the two-dimensional code reading unit 400 combines the divided data, restores the original output data, converts the data into a predetermined data format, and reads the data. The data is supplied to the read data storage unit 401 as data. The read data storage unit 401 stores the supplied data in the data storage unit 42 or the like (step S206). And the control part 40 makes a reading mode a non-selection state, and performs the process of step S201 again.

  When the display mode is selected by the user (step S203; display mode), the read data display control unit 402 reads the read data stored in the read data storage unit 401 from the data storage unit 42 or the like (step S208). Then, the read data that has been read out is displayed on the liquid crystal screen or the like of the display unit 43 in a predetermined manner (step S209). In this case, the display mode of the read data is arbitrary. For example, when the read data is composed of a text character string, it may be displayed as it is, or may be processed and displayed so that the data is easy to see, such as graphing.

  Alternatively, the display may be performed using a plurality of read data stored in the data storage unit 42 or the like. In this way, for example, a plurality of types of data (for example, trends for each time of temperature and electric energy) in a single equipment device 2 are superimposed and displayed, or data of a plurality of equipment devices 2 are compared. It is possible to display the graph in the form.

  FIG. 12 illustrates an example of a temperature-power amount graph, and FIG. 13 illustrates an example of a power amount comparison graph for each equipment device 2. As shown in these figures, a bar graph of electric energy is designated on the plan view based on the positional relationship between the plan view and each facility device 2 that are displayed in combination with a plurality of read data. And can be displayed in the position. In the latter case, the data of the plan view is stored in the data storage unit 42 and the like, and can be appropriately called by the control unit 40 when the two-dimensional code processing program is activated. In addition, the information processing terminal 4 may obtain the data of the plan view in any way, and may obtain it by data communication via the communication unit 41, for example, or may be a two-dimensional code displayed by the equipment operation terminal 3 6 may be embedded.

  When the end mode is selected by the user (step S203; end mode), the control unit 40 ends the two-dimensional code handling process. When the two-dimensional code corresponding process is completed, a standby screen or the like is displayed on the liquid crystal screen or the like of the display unit 43, for example.

  As described above in detail, in the facility management system 1 according to the present embodiment, the facility operation terminal 3 represents and displays data (output data) to be output to the outside in a two-dimensional code. When the size of the output data is large, a plurality of two-dimensional codes are generated, and each two-dimensional code is sequentially switched and displayed at a constant interval. Therefore, even an inexpensive equipment operation terminal that does not have a communication interface for outputting data to external equipment transmits large-capacity data such as various equipment operation data and trend data of measurement data to external equipment. It becomes possible to do.

  In addition, it is possible to manage and view various types of data on information processing terminals such as mobile phones that are generally used, so that the operating status data of equipment can be managed without investing in new equipment. Or the like.

  In the present embodiment, the facility device 2 and the facility operation terminal 3 are described as separate devices. However, the function of the facility operation terminal 3 of the present invention is implemented in the facility device 2 and is displayed on the display unit on the facility device 2. The two-dimensional code corresponding to the driving state data or the like may be displayed in the same manner.

  In the present embodiment, the facility operation terminal 3 is described as a single system. However, in the facility management system in which a plurality of facility operation terminals are installed, each piece of output data is received from a plurality of facility operation terminals. It may be acquired at the processing terminal so that data of a plurality of facility operation terminals can be managed.

  In addition, there is no limitation on the content of data output by the equipment operation terminal. For example, model information such as equipment equipment model name, serial number, capability value, equipment name and service contact information set in the equipment operation terminal, backup, etc. Various setting information and the like may be output in the form of a two-dimensional code.

  Moreover, the facility operation terminal is not limited to when a data output command is input from the user, and may automatically generate and display a two-dimensional code at a predetermined timing. For example, the operation state data of the equipment whose operation state has changed may be automatically selected as output data, and a two-dimensional code corresponding to the output data may be generated and displayed.

(Embodiment 2)
Then, the equipment management system concerning Embodiment 2 of the present invention is explained.

  In a two-dimensional code reader function that is pre-installed in a general information processing terminal, when a read image is read again, it is normal to display an error message on the screen to notify duplicate reading. . Then, for example, when the plurality of divided two-dimensional codes 6 are sequentially displayed on the facility operation terminal 3 of the first embodiment, the information processing terminal 4 displays the error message, and the user confirms the message. The possibility that the display of the two-dimensional code 6 by the equipment operation terminal 3 is switched during the operation cannot be denied. In this case, it may take a long time to read all the two-dimensional codes 6 by the information processing terminal 4.

  FIG. 14 is a timing chart for explaining the occurrence of a duplicate error. In this example, after the two-dimensional code 6B is read, it is indicated that the next reading process is started while the two-dimensional code 6B is still displayed. For this reason, the information processing terminal 4 reads the two-dimensional code 6B twice, and as a result, an image duplication error message is displayed.

  Further, in FIG. 14, while the error message is displayed, the display time of the two-dimensional code 6C has passed, and at the next reading timing, the already read two-dimensional code 6A is read again, and the image is displayed again. It also shows that duplicate error messages are displayed.

  In the present embodiment, a method for displaying a two-dimensional code on the facility operation terminal 3 will be described so that the image duplication error message as described above is not displayed.

  In addition, although the equipment management system of this embodiment differs in the display timing of the two-dimensional code output from the equipment operation terminal 3 from the equipment operation terminal 3 of Embodiment 1, about the other points, the equipment management system of Embodiment 1 1 and performs the same operation.

  In the equipment operation terminal 3 of the present embodiment, the two-dimensional code generation unit 341 of the control unit 34, as in the case of the first embodiment, the size of the output data designated by the user exceeds the preset data size threshold. If so, a plurality of two-dimensional codes 6 are generated from the output data. The two-dimensional code display control unit 342 sequentially switches and displays the plurality of generated two-dimensional codes 6. After the first two-dimensional code 6 is displayed, the next (second) two-dimensional code 6 is displayed. Instead of displaying immediately, a period of non-display state is provided for a certain time, and then the next two-dimensional code 6 is displayed. Hereinafter, this is sequentially repeated. In other words, the two-dimensional code display control unit 342 intermittently sequentially switches and displays the generated two-dimensional codes.

  The display time and the non-display time are adjusted according to the time required for reading the two-dimensional code in the information processing terminal 4. In this embodiment, the display time of the two-dimensional code can be shortened compared to the first embodiment, but it is assumed that the information processing terminal 4 secures a time that allows the two-dimensional code to be read sufficiently.

  FIG. 15 is a timing chart showing display switching timing of the plurality of two-dimensional codes 6 displayed on the facility operation terminal 3 in the present embodiment.

  As shown in FIG. 15, the facility operation terminal 3 provides a state (non-display time period) in which the two-dimensional codes 6A to 6B are not displayed for a certain period of time at the timing of switching the two-dimensional codes 6A to 6B. For this reason, it can prevent that the information processing terminal 4 reads the same two-dimensional code 6A-6B again, and can prevent the situation where an image duplication error message is displayed.

  In this embodiment, the non-display time zone is provided at the switching timing of the two-dimensional code 6, but it is not always necessary to display nothing in this time zone. For example, a message such as an image number or “please wait for a while” may be displayed, or the next two-dimensional barcode 6 may be displayed with a reduced brightness until it cannot be recognized. In short, any image that the information processing terminal 4 does not recognize as the two-dimensional code 6 can be displayed regardless of the content.

  Further, the facility operation terminal 3 may be provided with a function that allows the user to appropriately adjust the display time and non-display time zone of the two-dimensional code 6.

  As described above, according to the equipment management system according to the present embodiment, when the equipment operation terminal 3 displays the two-dimensional code 6 in a divided manner, information is provided by providing a non-display time zone at the switching timing. In the processing terminal 4, it is possible to prevent the two-dimensional code 6 that has already been read from being read continuously and to prevent the occurrence of an image duplication error.

Next, when the transmission mode is selected by the user, the read data transmission unit 403 reads the read data stored in the data storage unit 42 and the like, and sends the read data to the remote management server 8 via the wide area network 9. Send.

  The read data transmitted from the information processing terminal 4 is received by the communication unit 80 of the remote management server 8 and supplied to the read data receiving unit 840. The read data receiving unit 840 analyzes the read data, divides it into data types (operating state data, history data), and stores them in the data storage unit 83.

  The read data processing unit 841 reads necessary data from the data storage unit 83 in accordance with an instruction from the user, etc., processes the read data into equipment units, tenants, data types, charging groups, etc. The stored data is stored in the data storage unit 83. At this time, the processed data may be displayed through the display unit 81 and further processed by the user through the input unit 82.
