The other operation data 275 includes the date and time when the operation terminal 3 was operated by the user, an identifier (operation source address) that can identify the operation terminal 3 operated by the user, and the equipment that is the target of the instruction indicated by the operation by the user An identifier (operation destination address) that can identify the device 2 and information indicating the operation content by the user are included. The other operation data 275 is also called a second history. The storage unit 205 functions as a second operation data storage unit 305 that stores a second history of operations performed by the user on the operation terminal 3.

In the present embodiment, the operation terminal 3 and the equipment 2 communicate with each other by wire. The control unit 204 of the management device 4 acquires the communication packet transmitted / received on the communication path between the operation terminal 3 and the equipment 2 and analyzes the acquired communication packet, thereby using the operation terminal 3 by the user. The information which shows the instruction | indication to the installed equipment 2 is acquired. The communication unit 201 and the control unit 204 cooperate to function as an acquisition unit 304 that acquires an instruction using the operation terminal 3 capable of communicating with the equipment device 2 and indicating an instruction to the equipment device 2 by the user. . Note that the operation terminal 3 and the equipment 2 may communicate wirelessly.

The transmission source address is an address assigned in advance to the operation terminal 3 operated by the user. The transmission destination address is an address previously assigned to the instruction target equipment 2.

In this embodiment, a unique number defined in the dedicated protocol is used for the address assigned to the operation terminal 3 and the equipment 2, but a character, a symbol, or the like may be used.

The communication log 276 indicates a history of communication between the facility device 2 and the management device 4, a history of communication between the facility devices 2, and a history of communication between the facility device 2 and the operation terminal 3. The communication log 276 includes a header portion including a communication date and time, a transmission source address, and a transmission destination address, and a data portion (payload) that stores data to be transmitted and received. The communication log 276 includes not only a communication history related to user operations, but also a communication history between the facility devices 2. The storage unit 205 functions as a communication history data storage unit 306 that stores a history of communication between the facility device 2 and the management device 4.

A part of the extracted data 277 is extracted from the own operation data 274, the other operation data 275, and the communication log 276 by the control unit 204 when a predetermined extraction condition for extracting the extracted data is satisfied. Associated data. Data extracted from the self-operation data 274, data extracted from the other operation data 275, and data extracted from the communication log 276 are associated with each other and stored in the storage unit 205 as extracted data 277. Of the extracted data 277, the data extracted from the own operation data 274 and the data extracted from the other operation data 275 are also referred to as a third history. Of the extracted data 277, data extracted from the communication log 276 is also referred to as a fourth history. The storage unit 205 functions as an extraction data storage unit 308 that stores the extraction data 277.

The extraction condition is, for example, “the management apparatus 4 receives an abnormality notification from the equipment device 2 that an abnormality has occurred in the equipment device 2”. When the control unit 204 of the management device 4 receives the abnormality notification from the equipment 2, the control unit 204 selects a certain period before and after the date and time indicated by the abnormality notification from all the self-operation data 274 stored in the storage unit 205 (for example, abnormality notification). 1 hour etc. from 30 minutes before the date and time when the error notification is received to 30 minutes after the date and time when the abnormality notification is received. Similarly, when the control unit 204 receives the abnormality notification from the equipment device 2, the data recorded in a certain period before and after the date and time indicated by the abnormality notification from all the other operation data 275 stored in the storage unit 205. To extract. In addition, when the abnormality notification is received from the equipment 2, the control unit 204 extracts, from all the communication logs 276 stored in the storage unit 205, data recorded for a certain period before and after the date and time indicated by the abnormality notification. To do. Then, the control unit 204 stores the extracted data in the storage unit 205 as the extracted data 277 in association with each other.

As the extraction unit 307, the control unit 204 extracts data within a target period including the date and time when the extraction condition is satisfied from the own operation data 274, other operation data 275, and the communication log 276 when a predetermined extraction condition is satisfied. Function.

Alternatively, the extraction condition may be “the user has instructed the operation to the equipment device 2”. The control unit 204 of the management apparatus 4 is stored in the storage unit 205 when any instruction is input from the user via the screen displayed by the management apparatus 4 or when any instruction is received from the operation terminal 3. From all the self-operation data 274, the other operation data 275, and the communication log 276, the data for a certain period before and after the date when the instruction is input from the user or the date when the instruction is received from the operation terminal 3 are extracted and associated with each other. Store as data 277. The content of the instruction from the user is arbitrary.

The extraction condition may be “an instruction to cause the equipment 2 to perform a specific operation”. For example, when the user inputs an instruction to operate the equipment 2 in an operation mode in which heating or cooling is performed with less power consumption than usual, that is, a so-called energy saving mode, the control unit 204 of the management device 4 stores the storage unit 205, data of a certain period before and after the date and time when the operation in the energy saving mode is started are extracted from all the self-operation data 274, other operation data 275, and the communication log 276 stored in 205, and are extracted as the extracted data 277 in association with each other. Remember.

The extraction condition may be “the room temperature indicated by the environmental data has increased by a predetermined value or more”. When the control unit 204 of the management device 4 receives environmental data indicating that the indoor temperature has risen by a predetermined value or more from the equipment device 2, all of the self-operation data 274 stored in the storage unit 205 and other data are stored. From the operation data 275 and the communication log 276, data for a certain period before and after the date and time when the environmental data indicating that the indoor temperature has risen by a predetermined value or more are received from the equipment 2 are extracted and associated with each other. Store as 277.

The extraction condition may be “the target air conditioning temperature has been changed by the user”. When the instruction to change the target temperature is input from the user via the screen displayed by the management apparatus 4 or the instruction to change the target temperature is received from the operation terminal 3, the control unit 204 of the management apparatus 4 Data of a certain period before and after the date and time when the instruction to change the target temperature is input is extracted from all the self-operation data 274, the other operation data 275, and the communication log 276 stored in the storage unit 205 and associated with each other. Stored as extracted data 277.

The control unit 204 of the management device 4 can arbitrarily set the extraction condition, and generates the extraction data 277 when determining that the set extraction condition is satisfied. Thus, the extraction data 277 is generated by being triggered when it is determined that the extraction condition is satisfied.

In the following explanation, satisfying the extraction condition is also expressed as an event occurring. When the event occurs, the control unit 205 of the management device 4 generates the extracted data 277.

The storage period for storing the own operation data 274, the other operation data 275, and the communication log 276 is arbitrary. The control unit 204 of the management apparatus 4 determines the storage period of the self-operation data 274, the other operation data 275, and the communication log 276, for example, for the latest one month, and deletes old records that have passed this period. May be. This saves memory.

Alternatively, the control unit 204 of the management device 4 sets the maximum size that can store the own operation data 274, the other operation data 275, and the communication log 276 in the storage unit 205. New records may be added while sequentially deleting from the oldest record.

The control unit 204 of the management apparatus 4 sets an upper limit on the number of records that can store the own operation data 274, other operation data 275, and the communication log 276 in the storage unit 205. A new record may be added while sequentially deleting from the record with the oldest recorded date and time so as to fit in the number.

The user may be able to set a storage period for storing the own operation data 274, the other operation data 275, and the communication log 276. The control unit 204 of the management device 4 may receive an input designating the retention period from the user and sequentially delete records that have exceeded the input retention period.

The control unit 204 of the management device 4 may set different storage periods for each type of the equipment 2 such as 1 month for an air conditioner and 10 days for a lighting device.

For example, the control unit 204 of the management device 4 may be configured such that one month if the source address or destination address is a living room air conditioner, and ten days if the source address or destination address is a bedroom air conditioner. In addition, a different retention period may be set for each equipment device 2.

For example, if an instruction from the user is input via the screen displayed by the management apparatus 4, the control unit 204 of the management apparatus 4 receives the instruction from the user via the operation terminal 3 for one month. For example, a different storage period may be set for each operation unit to which an instruction from the user is input, such as 10 days.

Next, details of processing executed in the management apparatus 4 will be described.

FIG. 3 shows a functional configuration of the management device 4.

Fig. 4 shows an example of a screen that accepts input from the user. There are a plurality of types of screens displayed on the display 251, and different screen IDs are associated with the screens in advance. Each object on the screen is associated with a unique object ID in advance.

For example, the screen shown in FIG. 4 is associated with the screen ID “101”. In addition, the component ID “1001” corresponds to the button 401 corresponding to the operation start instruction, and the component ID “1002” corresponds to the instruction to set the operation mode to the cooling corresponding to the button 402 corresponding to the operation stop instruction. The button 403 has a component ID “1003”, the button 404 corresponding to the instruction to set the operation mode to heating has the component ID “1004”, and the button 405 corresponding to the instruction to set the operation mode to blow has a component. The part ID “1006” is assigned to the button 406 corresponding to an instruction to increase or decrease the target temperature by a predetermined value with the ID “1005”, and the part ID is assigned to the button 407 corresponding to the instruction to cancel the input content. The component ID “1008” is associated with the button 408 corresponding to the instruction to apply the input content “1007”.

FIG. 5 shows a flow of a saving process in which the management apparatus 4 saves the history that the object in the screen is operated by the user as the self-operation data 274. When the control unit 204 of the management apparatus 4 detects that an object in the screen displayed on the display 251 is operated by the user, the control unit 204 starts the storage process illustrated in FIG.

When the control unit 204 of the management device 4 detects an operation on the object by the user, the date and time when the object was operated by the user, the screen ID indicating the screen operated by the user, and the object indicating the object operated by the user ID is discriminated (step S501).

The control unit 204 of the management device 4 acquires an object state indicating the state of the object operated by the user (step S502).

For example, in FIG. 4, when the button 401 labeled “Start” is operated by the user, the control unit 204 of the management apparatus 4 has an object ID “1001” indicating the object operated by the user, In addition, it is determined that the object state corresponding to the object has changed from “non-selected” to “selected”.

Further, for example, when the button 402 labeled “START” is operated by the user in a state where the button 402 labeled “STOP” is selected before the operation by the user, the control unit 204 of the management device 4 , It is determined that the object state of the button 402 has changed, and it is determined that the object state of the object whose object ID is “1002” has changed from “selected” to “not selected”.

Then, the control unit 204 of the management apparatus 4 stores the operation date / time, the screen ID, the object ID, and the information indicating the object state determined in step S501 in the storage unit 205 as the own operation data 274 (step S503).

As described above, the self-operation data 274 indicating the history of the screen operation by the user is stored in the storage unit 205. The stored self-operation data 274 is searched using the date and time operated by the user as a key and displayed on the display 251. The image processing unit 202 and the control unit 204 cooperate to function as a display instruction unit 309 that instructs the display 251 to display the extracted data 277.

For example, when an instruction to display a history of screen operations is input from the user, the control unit 204 of the management device 4 determines the latest predetermined number from the own operation data 274 (for example, 10 items in order from the current time). And the date and time operated by the user, the screen ID, and the object ID are acquired. Based on the object data 273, the control unit 204 determines the screen corresponding to the acquired screen ID and the content of the operation corresponding to the acquired object ID. Then, as illustrated in FIG. 6, the control unit 204 displays the date and time operated by the user, the screen name corresponding to the screen ID, and the operation content corresponding to the object ID on the display 251.

Although not shown in the flowchart of FIG. 5, the control unit 204 of the management device 4 transmits an operation command to the equipment 2 based on the detected screen operation by the user, and operates the equipment 2 according to the operation command. Let

Next, a flow of processing in which the equipment device 2 operates based on an instruction from the user using the operation terminal 3 will be described with reference to FIG. In the present embodiment, two operation terminals 3 (a first operation terminal and a second operation terminal) can accept an instruction to the same equipment 2 from a user.

When the first operation terminal detects an operation input by the user (step S701), the first operation terminal transmits an operation command based on the operation input to the equipment device 2 (step S702). For example, when the first operation terminal detects an instruction input to start the heating operation, the first operation terminal transmits an operation command to the facility device 2 to start the heating operation.

When the facility device 2 receives the operation command, the facility device 2 executes an operation based on the operation command (step S703). For example, when the operation command transmitted in step S702 is a command for starting heating, the facility device 2 starts the heating operation.

The facility device 2 transmits response data for the received operation command to the first operation terminal that is the transmission source of the operation command (step S704).

The response data includes, for example, information indicating that the operation command has been normally received (or that the operation command has not been normally received), or information indicating that the operation based on the operation command has been successfully started (or has failed). included.

The facility device 2 transmits a state notification indicating that the operation state has been changed by executing an operation based on the operation command from the first operation terminal to the first operation terminal that is the transmission source of the operation command. (Step S705).

Further, the equipment device 2 transmits a status notification to the second operation terminal (step S706).

Furthermore, the facility device 2 transmits a status notification to the management device 4 (step S707). The control unit 204 of the management device 4 updates the operation data 271 and updates the communication log 276 based on the state notification.

The process flow when the second operation terminal detects an operation input by the user is the same. That is, when the second operation terminal detects an operation input by the user, the second operation terminal transmits an operation command based on the operation input to the equipment device 2. The equipment 2 executes an operation based on the operation command, transmits response data to the received operation command to the second operation terminal, and sends a status notification to the second operation terminal, the first operation terminal, and the management device 4. Send.

Next, a storage process flow in which the management device 4 stores the history of operation of the operation terminal 3 by the user as the other operation data 275 will be described with reference to FIG.

When the control unit 204 of the management device 4 receives a communication packet transmitted from the operation terminal 3 to the equipment device 2 (or from the equipment device 2 to the operation terminal 3) (step S801), all or part of the communication packet is communicated. The log 276 is stored in the storage unit 205 (step S802).

The control unit 204 of the management device 4 of the present embodiment stores the communication log 276 in which the communication time, the transmission source address, the transmission destination address, and the communication content included in the received communication packet are extracted in the storage unit 205. However, the storage format is not limited by the present invention, and for example, data included in a communication packet including such information may be stored in the storage unit 205 as it is.

The control unit 204 of the management device 4 analyzes the data stored in the communication packet, and determines whether or not the management device 4 includes an instruction to the management target equipment 2 (step S803).

When it is determined that the operation instruction to the management target equipment 2 by the management apparatus 4 is included (step S803; YES), the control unit 204 of the management apparatus 4 transmits the date and time when the communication packet is transmitted, the transmission source address, and the transmission The destination address and the operation content are acquired (step S804), and stored in the storage unit 205 as other operation data 275 (step S805).

In addition, the control part 204 of the management apparatus 4 does not preserve | save other operation data 275, when it determines with the communication packet not including the instruction | indication to the equipment 2 of the management object by the management apparatus 4 (step S803; NO). For example, the heartbeat signal periodically transmitted / received regardless of whether there is an input from the user or the history regarding the transmission / reception of data that does not require a response is not included in the other operation data 275.

As described above, when the user operates the operation terminal 3 instead of the management device 4 and inputs an instruction, the management device 4 stores the other operation data 275. Therefore, the user operates which operation terminal 3 and which equipment It is possible to trace later whether an instruction to the device 2 has been input.

Next, a management process flow in which the management apparatus 4 generates and displays the extracted data 277 will be described with reference to FIGS. 9 and 10. This management process is periodically and repeatedly executed by the management device 4.

As described above, the extraction condition is, for example, that “the management apparatus 4 receives an abnormality notification from the equipment device 2 that an abnormality has occurred in the equipment device 2” or “an operation instruction from the user to the equipment device 2. It is optional.

The control unit 204 of the management device 4 determines whether or not the extraction condition is satisfied (step S901).

When it is determined that the extraction condition is not satisfied (step S901; NO), the control unit 204 of the management device 4 ends the management process. When it is determined that the extraction condition is satisfied (step S901; YES), the control unit 204 of the management device 4 acquires the self-operation data 274 within the target period including the time when it is determined that the extraction condition is satisfied (step S902). ).

Here, the control unit 204 of the management device 4 determines that the extraction condition is satisfied from the date and time when the instruction is input from the user among all the records of the self-operation data 274 stored in the storage unit 205. Records included between time T2 before time T1 and time T3 after time T1 are extracted.

The length from time T2 to time T1 and the length from time T1 to time T3 may be the same or different.

In the present embodiment, the length from time T2 to time T1 and the length from time T1 to time T3 are both the same fixed value. The target period is determined, for example, from 30 minutes before time T1 to 30 minutes after time T1.

Further, the control unit 204 of the management device 4 acquires other operation data 275 within the target period including the time when it is determined that the extraction condition is satisfied (step S903).

Here, the control unit 204 of the management device 4 determines that the extraction condition is satisfied from the date and time when the instruction is input from the user among all the records of the other operation data 275 stored in the storage unit 205. Records included between time T4 before time T1 and time T5 after time T1 are extracted.

The length from time T4 to time T1 and the length from time T1 to time T5 may be the same or different. However, it is desirable to make time T2 and time T4 coincide, and make time T3 and time T5 coincide.

Further, the control unit 204 of the management device 4 acquires the communication log 276 within the target period including the time when it is determined that the extraction condition is satisfied (step S904).

Here, the control unit 204 of the management device 4 determines that the date and time when the instruction is input from the user among all the records of the communication log 276 stored in the storage unit 205 is that the extraction condition is satisfied. Records included between time T6 before T1 and time T7 after time T1 are extracted.

The length from time T6 to time T1 and the length from time T1 to time T7 may be the same or different. However, it is desirable that the time T2, the time T4, and the time T6 are matched, and that the time T3, the time T5, and the time T7 are matched.

Since the data amount of the communication log 276 generally tends to increase, the control unit 204 of the management apparatus 4 stores in the storage unit 205 instead of all the records of the communication log 276 stored in the storage unit 205. All records in the communication log 276 that have been determined and that include at least one of the determined transmission source address and transmission destination address may be extracted.

And the control part 204 of the management apparatus 4 respond | corresponds the data acquired from the self-operation data 274 at step S902, the data acquired from the other operation data 275 at step S903, and the data acquired from the communication log 276 at step S904. In addition, the extracted data 277 is stored in the storage unit 205 (step S905).

Further, the control unit 204 of the management device 4 displays the extracted data 277 generated in step S905 on the display 251 (step S906).

FIG. 10 shows a display example of the extracted data 277. FIG. 10 shows the time (18:16) when the management apparatus 4 receives the abnormality report from the equipment 2 when the above extraction condition is “the management apparatus 4 has received the abnormality report from the equipment 2”. The self-operation data 274, the other operation data 275, and the communication log 276 are displayed together for 15 minutes before and after (00 seconds) (that is, from 18:01:00 to 18:30:59).

Although the communication log 276 is displayed in a simplified manner in FIG. 10, the communication log 276 includes not only a communication log in communication between the management apparatus 4 and the equipment 2 but also an outdoor unit and an indoor unit. Communication log in communication between communication equipment and communication log in communication between equipment device 2 and operation terminal 3 (when there are a plurality of operation terminals 3, each communication in communication between equipment device 2 and operation terminal 3) Log), a communication log or the like in communication between the facility devices 2 may be included.

According to the present embodiment, the management system 1 causes the occurrence of an event even when there are a plurality of operation terminals 3 that can be operated by the user or even when there are a plurality of managed equipment 2. It is possible to present the user's operation history, communication history, and the like, which are useful for investigations, in an easy-to-understand manner. The management system 1 can automatically extract information that is valuable to the user from the user's operation history, communication history, etc., and present it to the user, triggered by the extraction condition being satisfied. .

Further, according to the present embodiment, since the operation history and communication log by the user before and after the occurrence of the specific event can be viewed on the same screen, the operation analysis by the management system 1 is facilitated. For example, when a problem occurs in the management system 1, the user can obtain information useful for pursuing the cause of the problem by browsing the display of the extracted data 277 illustrated in FIG.

In addition, according to the present embodiment, the user can view the extracted data 277 when the indoor environment such as the indoor temperature and humidity changes greatly or when the indoor environment deviates from the assumed range. Information can be obtained to help investigate the causes of environmental changes.

Moreover, according to this embodiment, in addition to the user's operation history on the screen displayed by the management device 4 and the control history of the equipment 2 not depending on the user's operation, the user using the operation terminal 3 The operation history is also saved, and the user can view this history, so that the cause can be easily caused even when a complaint such as the equipment device 2 operating without permission or the equipment device 2 stopping without permission is received. It becomes possible to elucidate.

As described above, the self-operation data 274 stored in the storage unit 205 includes the date and time when the operation was performed by the user, the screen ID indicating the screen operated by the user, and the object ID indicating the object operated by the user. And information indicating the object state. Therefore, by using the self-operation data 274, the situation when the event occurs can be easily reproduced later. For example, when a failure occurs, a reproduction experiment or the like is performed using the self-operation data 274, thereby helping to investigate the cause of the failure.

In the present embodiment, the management device 4 saves the own operation data 274 indicating the operation by the user and the other operation data 275 in the storage unit 205, but transmits them from the management device 4 to the equipment 2 regardless of the operation by the user. Control information (for example, information related to operation schedule, operation or non-operation of energy saving control, restriction of target temperature, etc.) may be stored in the storage unit 205 and displayed together with the communication log 276. In this case, it is possible to determine whether the communication is triggered by the user's operation, such as transmission / reception of an operation command, or the communication not based on the user's operation by referring to the own operation data 274 and / or other operation data 275. is there.

The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Moreover, it is also possible to freely combine the constituent elements of the above-described embodiments.

In the above embodiment, the target period for generating the extraction data 277 is a fixed value such as 30 minutes before and after the time T1 when the extraction condition is satisfied. However, the control unit 204 of the management device 4 may change the target period according to the event that occurs.

Specifically, if the extraction condition is the first condition “the management device 4 receives an abnormality notification from the equipment device 2 that an abnormality has occurred in the equipment device 2”, the control unit 204 of the management device 4 If the target period is set to a first value (for example, 30 minutes before and after time T1) and the extraction condition is the second condition “the user has issued an operation instruction to the equipment 2”, the target period Is set to a second value (for example, 10 minutes before and after time T1). The first value and the second value can be arbitrarily changed.

The control unit 204 of the management device 4 may change the target period according to the time when the event occurs.

For example, if the time T1 when the extraction condition is satisfied is a first time zone (for example, from 7:00 to 21:00), the control unit 204 of the management device 4 sets the target period to the first value (for example, the time T1). If the time T1 is the second time zone (for example, from 0:00 to 7:00, and from 22:00 to 24:00), the target period is set to the second value (for example, the time T1). Set to 10 minutes before and after. The first value and the second value can be arbitrarily changed. The definition of the time zone can be arbitrarily changed.

The control unit 204 of the management device 4 may change the target period according to the frequency of events that have occurred in the past.

For example, the control unit 204 of the management device 4 sets the target period to the first value (for example, 30 minutes before and after the time T1) if the frequency that the extraction condition is satisfied is equal to or higher than a threshold (for example, 10 times or more in the past week) If the frequency at which the extraction condition is satisfied is less than a threshold (for example, 9 times or less in the past week), the target period is set to a second value (for example, 10 minutes before and after time T1). The first value and the second value can be arbitrarily changed. Further, the definition of the threshold value can be arbitrarily changed.

The management device 4 of the above embodiment includes a history of screen operations on the touch panel 252, a communication log of communication between the management device 4 and the facility device 2, and a communication log of communication between the facility device 2 and the operation terminal 3. From the above, the extraction data 277 is generated and displayed with the extraction condition being satisfied as a trigger. Since it is relatively easy to store operation and communication histories, the present invention can be applied to an existing system without greatly changing an existing software application.

Since the generated extracted data 277 is stored in the storage unit 205, the control unit 204 of the management device 4 reads out the extracted data 277 at an arbitrary timing and displays it on the display 251 not only when the extraction condition is satisfied. can do. For example, the user can call up and display the extracted data 277 generated with an event that occurred in the past as a trigger.

Further, the control unit 204 of the management device 4 may read the extracted data stored in the storage unit 205, reproduce the operation of the screen by the user using the extracted data 277, and display it on the display 251. For example, the control unit 204 of the management device 4 uses the extracted data 277 generated in response to the defect that occurred on the first date and time as the second date and time after the first date and time (for example, during maintenance of the management system 1). And the event that occurred on the first date and time can be reproduced on the second date and time. Thereby, the administrator can reproduce and verify the defect retroactively, and the efficiency of investigation of the cause of the defect by the administrator is improved.

Although the management device 4 of the above embodiment includes the display 251, the management device 4 may be connected to an external display device instead of the management device 4 not including the display 251. The control unit 204 of the management device 4 instructs the external display device to display the generated extracted data 277, and the external display device acquires and displays the extracted data 277 generated by the management device 4. Good.

A program for operating the computer as all or part of the management device 4 is stored and distributed in a computer-readable recording medium such as a memory card, CD-ROM, DVD, or MO (Magneto Optical disk). This may be installed in another computer and operated as the above-described means, or the above-described steps may be executed.

Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.
