The present invention relates to a device monitoring apparatus, a device monitoring system, a registration terminal, and a device monitoring method for monitoring the power consumption of devices connected to power wiring.

In view of the increasing interest in the environment, an energy management system (hereinafter referred to as EMS) that efficiently uses energy has attracted attention (for example, see Patent Document 1 or 2). This EMS reduces power consumption by performing various operations such as visualization of power consumption of equipment (load equipment), control of power consumption of equipment, and advice to reduce power consumption of equipment to users (users). Let Therefore, the EMS needs to have a configuration for measuring power consumption by each device in order to appropriately perform these operations. In recent years, a method using a smart socket (hereinafter also simply referred to as a socket) has been proposed as a method for measuring the power consumption of a device. When the power connector of the device is inserted into the smart socket, the smart socket supplies power to the device, measures the power consumption of the connected device, and transmits it to the EMS controller using wireless communication or the like. According to this method, it is not necessary for the device itself to have a function of measuring power consumption or a function of communicating with an EMS controller. It can be measured.

(Knowledge that became the basis of the present invention)
In EMS using a smart socket for power consumption measurement, for example, a smart socket is individually provided for each device, and the device monitoring device receives the power consumption measurement result from the smart socket and monitors the power consumption of the device. Conceivable. In this configuration, the power consumption of each device can be individually monitored, but it is necessary to make the device monitoring device recognize which smart socket is connected to which device. Therefore, when registering a device in the EMS, the user needs to register the device and the smart socket in association with the device monitoring apparatus.

However, the operation of registering the device and the smart socket in association with each other is complicated, and the user is required to perform a complicated operation such as inputting the device model, so the device and the smart socket are not correctly registered in the device monitoring apparatus. Things will also increase. In this case, since it becomes impossible to accurately monitor the power consumption of the device by the device monitoring device, it is difficult to reduce the power consumption of each device in the EMS.

Therefore, the device monitoring apparatus according to one aspect of the present invention is a device monitoring device that monitors the power consumption of the device connected to the power wiring, and collects the power consumption pattern of the device connected to the power wiring. The information collection unit and the contents of the registration operation performed on the device when registering the device as the monitoring target of the device monitoring apparatus are associated with the power consumption pattern of the device generated by the registration operation. Of the registration operation information holding unit, the registration operation content held by the registration operation information holding unit, the content of the registration operation performed on the target device that is a device to be registered as a monitoring target, and the registration operation information A registration operation guide generating unit for generating and notifying a registration operation guide for instructing an execution time; and the power information in a predetermined period determined based on the execution time indicated by the registration operation guide The power consumption pattern of the target device collected by the collecting unit and the power consumption pattern associated with the content of the registration operation indicated by the registration operation guide are collated to identify the power wiring to which the target device is connected A power consumption pattern matching unit; a power wiring specified by the power consumption pattern matching unit; and a device information registration unit that registers the target device in association with each other.

According to this aspect, the user does not need to perform a complicated registration operation, and the device monitoring apparatus automatically identifies the power wiring connected to the device that has requested registration, and the device that has requested registration. Register in association. As a result, the device monitoring apparatus can accurately register and register the device and the power wiring, and thus can accurately monitor the power consumption of the device.

For example, the target device is connected to the power wiring through a socket capable of detecting the power consumption of the connected device, and the power information collection unit collects the power consumption pattern of the target device from the socket. The device information registration unit registers the target device and the socket in association with each other.

According to this aspect, the device monitoring apparatus identifies the socket as the power wiring connected to the device that has requested registration, and registers it in association with the device that has requested registration. As a result, the device monitoring apparatus can accurately register the device and the socket in association with each other, and thus can accurately monitor the power consumption of the device.

For example, the registration operation information holding unit further associates the content of the registration operation with a communication pattern generated by the registration operation on a communication network in which the target device and the device monitoring apparatus are connected by the registration operation. The device monitoring device further includes a network information collection unit that collects the communication pattern on the communication network, an execution time indicated by the registration operation guide generated by the registration operation guide generation unit, Communication collected by the network information collection unit during a predetermined period based on a time length of a communication pattern generated on a communication network connected to the target device by the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit Correspondence between the pattern and the content of the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit A communication pattern matching unit that identifies an address on the communication network of the target device, and the device information registration unit is configured to identify an address on the communication network identified by the communication pattern matching unit. And the target device are registered in association with each other.

According to this aspect, the device monitoring apparatus further automatically identifies the address on the communication network of the device that has requested registration, and registers it in association with the device that has requested registration. Thereby, the device monitoring apparatus can register the address of the device on the communication network accurately and easily, and can accurately perform communication between the device and the device monitoring apparatus in the EMS.

For example, the registration operation information holding unit further includes an operation of the target device caused by the registration operation, a communication pattern of the target device caused by the registration operation, and a power consumption pattern of the target device caused by the registration operation. The communication pattern matching unit identifies the operation of the target device based on the communication pattern collected by the network information collecting unit, and the power consumption pattern matching unit The power consumption pattern collected by the power information collecting unit corresponding to the operation is collated with the power consumption pattern corresponding to the operation of the target device specified by the communication pattern matching unit held by the registered operation information holding unit. Thus, the target device connected to the power wiring is specified.

According to this aspect, the device monitoring apparatus can register the device and the power wiring in association with each other in consideration of the communication pattern on the communication network of the device that has requested registration.

For example, when the registration operation guide generation unit receives a registration request for a plurality of the target devices of the same type, each of the plurality of registration operation guides generated corresponding to the plurality of target devices is different. The plurality of registration operation guides are generated so as to include the time.

According to this aspect, even when a plurality of devices of the same type (model) are registered at the same time, the device monitoring apparatus executes the registration operation at different times. Can do.

For example, the registration operation information holding unit holds contents of a plurality of different registration operations, and the registration operation guidance generating unit receives the registration requests for the plurality of target devices of the same type, The plurality of registration operation guides are generated so that each of the plurality of registration operation guides generated corresponding to the above includes different contents of the registration operation.

According to this aspect, even when registering a plurality of devices of the same type at the same time, the device monitoring apparatus can register a plurality of devices separately because the contents of the registration operation are different.

For example, when the power information collection unit collects a power consumption pattern from a power wiring that is not associated with any device in the device information registration unit, the power information collection unit outputs a message that prompts registration of a device connected to the power wiring. To do.

According to this aspect, when there is an unregistered socket, the device monitoring apparatus can prompt the user to perform a registration operation.

For example, the power information collection unit is configured such that the power consumption pattern collected from the power wiring associated with the device in the device information registration unit is different from the device registered in association with the power wiring. If it is, a message prompting registration of the device connected to the power wiring is output.

Even if the device monitoring device correctly registers the socket, the device monitoring device accurately monitors the power consumption of the device if the correspondence between the device and the socket changes after that and the correspondence is not updated. Can not be. For example, if a device connected to two different sockets is replaced or another new device is connected to a registered socket, the power consumption of the device cannot be monitored accurately. However, according to this aspect, when the correspondence between the device and the socket changes, the user can be asked to register the device whose correspondence has changed, so even in this case, the power consumption of the device can be accurately monitored. can do.

For example, the registration operation information holding unit holds the contents of a plurality of different registration operations, and the registration operation guidance generation unit specifies the power wiring when the power consumption pattern matching unit fails to specify the power wiring. And generating a new registration operation guide including the content of the registration operation different from the content of the registration operation associated with the power consumption pattern used for the verification that failed, and the power consumption pattern verification unit Based on the execution time indicated by the new registration operation guide generated by the generation unit and the time length of the power consumption pattern of the target device generated by the registration operation indicated by the new registration operation guide generated by the registration operation guide generation unit The power consumption pattern measured during a predetermined period is collated with the power consumption pattern associated with the content of the registration operation indicated by the new registration operation guide, and Device identifies the connected power line.

According to this aspect, when the device monitoring apparatus fails in registration, the device monitoring apparatus can cause the registration operation to be performed again with a registration operation guide different from the failed registration operation guide.

For example, if the power consumption pattern matching unit fails to identify the power wiring, the power consumption pattern collected from the power wirings narrowed down in the failed matching, and the registered operation guidance generated by the registered operation guidance generating unit The power supply pattern associated with the content of the registration operation indicated by is again checked to identify the power wiring to which the target device is connected.

According to this aspect, the device monitoring device can narrow the range of sockets to be specified and specify sockets with high accuracy.

For example, the device monitoring apparatus further includes a power consumption pattern correction unit that corrects a power consumption pattern held by the registered operation information holding unit, and the power consumption pattern matching unit The power consumption pattern corrected by the power consumption pattern correction unit is collated with the power consumption pattern collected by the power information collection unit.

According to this aspect, the device monitoring apparatus can correct the power consumption pattern in consideration of, for example, variation depending on the socket model, so that the socket connected to the device that has requested registration in pattern matching can be accurately identified. can do.

For example, the device monitoring apparatus further includes a power consumption pattern correction unit that corrects a power consumption pattern collected by the power information collection unit, and the power consumption pattern matching unit is configured to match the power consumption pattern in the power consumption pattern matching. The power consumption pattern corrected by the power pattern correction unit is collated with the power consumption pattern associated with the content of the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit.

For example, the registered operation information holding unit associates the held power consumption pattern with a model of the power wiring, and the power consumption pattern matching unit collects the power information collecting unit in matching the power consumption pattern. The content of the registration operation indicated by the registration operation guide associated with the power consumption pattern and the model of the power wiring from which the power consumption pattern collected by the power information collection unit is obtained and generated by the registration operation guide generation unit Are compared with the power consumption pattern associated with.

According to this aspect, the device monitoring apparatus can perform pattern matching with a power consumption pattern that takes into account variations depending on the type of socket, for example. Therefore, the socket connected to the device that requested registration in pattern matching can be accurately identified. Can be identified.

A device monitoring system according to an aspect of the present invention includes the device monitoring device described above and an outlet capable of detecting power consumption of the connected device, and the power information collection unit of the device monitoring device includes: Collecting the power consumption pattern of a symmetric device that is a device to be registered as a monitoring target from the outlet, and the device information registration unit of the device monitoring apparatus registers the target device and the outlet in association with each other To do.

This produces the same effect as the above device monitoring device.

Also, a registration terminal according to an aspect of the present invention is a registration terminal that displays the registration operation guide generated by the device monitoring apparatus described above.

Thereby, since the registration terminal accepts an operation from the user to the device monitoring device, the device monitoring device can accurately register the device and the power wiring so that the power consumption of the device can be registered. Can be monitored accurately.

The device monitoring method according to one aspect of the present invention is a device monitoring method in a device monitoring apparatus that monitors power consumption of a device connected to a power wiring, and includes a power consumption pattern of the device connected to the power wiring. A power information collecting step for collecting the information, a content of a registration operation performed on the device when the device is registered as a monitoring target of the device monitoring apparatus, and a power consumption pattern of the device generated by the registration operation. Of the registration operation information holding step held in association with each other and the registration operation content held in the registration operation information holding step, the registration operation performed on the target device that is the device to be registered as the monitoring target A registration operation guide generation step for generating and notifying a registration operation guide for instructing the content and the execution time of the registration operation; and The power consumption pattern of the target device collected by the power information collection unit during a predetermined period determined based on the execution time is collated with the power consumption pattern associated with the content of the registration operation indicated by the registration operation guide.

(Embodiment 1)
First, the configuration of the EMS according to the first embodiment will be described. FIG. 1A is a first block diagram showing a schematic configuration of the EMS according to the present embodiment. FIG. 2A is a diagram showing an operation correspondence table held by the registered operation information holding unit of the EMS according to the present embodiment. FIG. 2B is a diagram showing a device correspondence table held by the device information registration unit of the EMS according to the present embodiment.

As shown in FIG. 1A, the EMS 1 includes a registration terminal 10, a plurality of smart sockets SS1 to SS4, and a device monitoring device 2, and includes a device A of model A, a device B of model B, and a device of model C. The power consumption of a plurality of devices A to D of different models of the device D of C and the model D is monitored. Note that the device model is information for identifying the device type including, for example, a device name such as a refrigerator, a television, an air conditioner, and a personal computer, a device manufacturer name, and a device model number.

The EMS 1 is, for example, a HEMS (Home Energy Management System) that manages the devices A to D as home appliances. Based on the monitoring results of the power consumption of the devices A to D, the EMS 1 visualizes the power consumption of the devices A to D, controls the power consumption, or provides advice and messages to the user, etc. Performs various operations to reduce power consumption.

The smart sockets SS1 to SS4 are sockets (also called outlets, taps or outlets) having functions of power supply and power consumption measurement, and are provided corresponding to any of the devices A to D, respectively. It is connected to a corresponding device in a state where power is supplied and power consumption of the corresponding device can be measured. Specifically, the smart socket SS1 is connected to the device A in a state where the power consumption of the device A can be measured. Similarly, the smart socket SS2 is connected to the device B in a state where the power consumption of the device B can be measured. The smart socket SS3 is connected to the device C in a state where the power consumption of the device C can be measured. The smart socket SS4 is connected to the device D in a state where the power consumption of the device D can be measured. At this time, the connection between the smart socket and the device is realized, for example, by inserting the power connector of the device into the smart socket, or by incorporating the function of the smart socket in a table tap or an outlet connecting the device and the power system. Is done.

Each of the smart sockets SS1 to SS4 transmits a measurement result (power consumption value) of power consumption to the device monitoring apparatus 2 by wireless communication or wired communication such as a specific low power wireless or ZigBee (registered trademark) system. The transmission of the measurement result of the power consumption from the smart sockets SS1 to SS4 to the device monitoring apparatus 2 is performed, for example, at a predetermined fixed period or at a predetermined time by an instruction from the device monitoring apparatus 2 or by a spontaneous operation.

The registration terminal 10 is a terminal used for a dialogue between the user and the EMS 1 and includes an input / output unit and a display unit. When registering a device in the EMS 1, the registration terminal 10 receives a device information input from a user and transmits a device registration request to the device monitoring device 2, and also describes the contents of the device registration operation and the device registration. The result is received from the device monitoring device 2. The device information is information including at least the device model, and the device information may include a device manufacturing number and a device ID.

The device monitoring device 2 is a controller that monitors the power consumption of the devices A to D and performs various operations for reducing the power consumption of the devices A to D based on the monitoring result. The device monitoring apparatus 2 includes a power information collecting unit 21, a registered operation information holding unit 22, a registered operation guidance generating unit 23, a power consumption pattern matching unit 24, and a device information registering unit 25.

The power information collection unit 21 is a reception unit that receives the measurement results of power consumption transmitted from the smart sockets SS1 to SS4, and collects the measurement results of power consumption by the smart sockets SS1 to SS4, for example. The device monitoring apparatus 2 monitors the power consumption of the devices A to D based on the power consumption measurement result collected by the power information collecting unit 21.

The power information collecting unit 21 consumes the power consumption measurement results measured by the smart sockets SS1 to SS4 during the period based on the power pattern designation timing received from the registration operation guide generating unit 23 when the device is registered in EMS1. It transmits to the power pattern matching unit 24. Specifically, the power information collection unit 21 uses the power consumption measurement results measured by the smart sockets SS1 to SS4 during the period based on the power pattern designation timing for each of the smart sockets SS1 to SS4. The time variation pattern (measured power consumption pattern) is derived and transmitted to the power consumption pattern matching unit 24. In this transmission, the measured power consumption pattern and the smart that transmitted it are identified so that the power consumption pattern matching unit 24 can identify which smart socket SS1 to SS4 each of the measured power consumption patterns is from. The identification information of the socket is transmitted in association with it. Note that the smart sockets SS1 to SS4 measure the power consumption of the device with an accuracy that allows the power consumption pattern matching unit 24 to check the time variation pattern of the power consumption of the device.

The registration operation information holding unit 22 receives the device information of the device requested to be registered from the registration terminal 10 when registering the device in the EMS 1 and transmits the received device information to the device information registration unit 25.

The registration operation information holding unit 22 holds an operation correspondence table provided for each of the models A to D, and when receiving a device registration request from the registration terminal 10 when registering the device in the EMS 1, the registration request information is received. Operation correspondence table for the model of the selected device. In the operation correspondence table, as shown in FIG. 2A, a plurality of contents of registration operations to the device are registered, and the contents of each registered operation include a pattern of time variation of power consumption of the device due to the registration operation. (Assumed power consumption pattern) is associated. For example, in the operation correspondence table provided for the model A, “power activation” is registered in association with a predetermined assumed power consumption pattern of the model A device as the content of the registration operation of the model A device. In addition, the content of the registration operation in the operation correspondence table includes a registration operation in which the time fluctuation of the power consumption generated in the device on which the registration operation is performed can be distinguished from the time fluctuation of the power consumption of other devices. Is preferably registered.

The registration operation information holding unit 22 selects the content of any registration operation from the extracted operation correspondence table when registering the device in the EMS 1. Then, the registration operation information holding unit 22 transmits the content of the selected registration operation and the assumed power consumption pattern associated with the content of the selected registration operation to the registration operation guidance generation unit 23 and selects it in the operation correspondence table. The assumed power consumption pattern associated with the contents of the registered operation is transmitted to the power consumption pattern matching unit 24.

The registration operation guide generation unit 23 generates a registration operation guide from the content of the registration operation transmitted from the registration operation information holding unit 22 when registering the device in the EMS 1 and transmits the registration operation guide to the registration terminal 10. This registration operation guidance is guidance indicating the content of the registration operation of the device requested to the user in order to register the device and the execution time (execution timing) for performing the registration operation. The execution timing included in the registration operation guide is set by the registration operation guide generation unit 23, and is set to an arbitrary time that can be executed by the user after receiving the device registration request. The content of the registration operation included in the registration operation guide is the content of the registration operation transmitted from the registration operation information holding unit 22.

Also, the registration operation guidance generation unit 23 transmits to the power information collection unit 21 a power pattern designation timing indicating a period (time) indicated by the execution timing to a period corresponding to the time length of the assumed power consumption pattern.

The power consumption pattern matching unit 24 matches a measured power consumption pattern transmitted from the power information collecting unit 21 with an assumed power consumption pattern transmitted from the registered operation information holding unit 22 when the device is registered in the EMS 1 ( Verification). Then, as a result of pattern matching, the power consumption pattern matching unit 24 identifies the smart socket that has transmitted the actually measured power consumption pattern that matches the assumed power consumption pattern as a smart socket connected to the device that has requested registration. . Then, the power consumption pattern matching unit 24 transmits the identified smart socket identification information to the device information registration unit 25.

The device information registration unit 25 holds a device correspondence table in which a plurality of correspondence relationships between device information and smart socket identification information are registered. When registering a device in the EMS 1, the device information registration unit 25 transmits the smart socket identification information transmitted from the power consumption pattern matching unit 24 and the registration operation information storage unit 22 to the device correspondence table held. Registered in association with the device information.

When the device is registered in the device monitoring device 2 in response to the device registration request to the device monitoring device 2, the device information registration unit 25 transmits the device registration result to the registration terminal 10 as the device registration result. For example, in the device correspondence table, as shown in FIG. 2B, the device information of the device A is registered in association with the identification information of the smart socket SS1.

Note that the power information collection unit 21 receives the power pattern received from the registration operation guidance generation unit 23 in consideration of the case where the execution of the registration operation of the actual user is shifted by several seconds with respect to the execution timing included in the registration operation guidance. Measured power consumption patterns are derived for each of the smart sockets SS1 to SS4 based on the measurement results of the power consumption measured by the smart sockets SS1 to SS4 during a period several seconds before and after the specified timing.

Note that the configuration of the EMS may be a configuration in which the smart sockets SS1 to SS4 are provided in the distribution board. FIG. 1B is a second block diagram illustrating a schematic configuration of the EMS according to the present embodiment. In FIG. 1B, the smart sockets SS1 to SS4 are arranged inside the distribution board 13, measure the power flowing through the power line connecting the system power supply 14 and the device (or outlet), and consume the measured power. The power is transmitted to the power information collecting unit 21.

In FIG. 1B, the smart sockets SS1 to SS4 can be replaced with ones that realize a function of measuring the power flowing through the power line for each power line and transmitting the measured value for each power line to the power information collecting unit 21. is there. That is, the configuration of the EMS may be a configuration using a power monitoring device that measures the power flowing through a plurality of power lines in one housing instead of the mart sockets SS1 to SS4.

In FIG. 1B, one smart socket is used for a power line to which one device (or outlet) is connected. However, one smart socket is used for a power line to which a plurality of devices (or outlets) are connected. May be. In this case, the power that can be measured by the smart socket is the total power consumption of a plurality of devices. In this case, the power consumption pattern matching unit 24 identifies devices included in the plurality of devices from the total power consumption of the plurality of devices. Specifically, for example, it is realized by acquiring the power consumption pattern of the device to be specified during a period in which fluctuations in power consumption of devices other than the device to be specified are relatively small. In this case, the device monitoring apparatus 2 determines the operation status of the device as necessary.

Next, a device registration process flow in the EMS 1 according to the first embodiment will be described. FIG. 3 is a sequence diagram showing a flow of device registration processing in EMS 1 according to the present embodiment. FIG. 4 is a diagram for specifically explaining pattern matching of the power consumption pattern matching unit 24 in the EMS according to the present embodiment. In the description of FIG. 3, it is assumed that the device D is not registered in the EMS 1 and the flow of processing for registering the device D in the EMS 1 will be described. However, the same processing is performed in the registration of other devices.

As shown in FIG. 3, first, when the registration terminal 10 receives a registration request for the device D from the user (step S <b> 1), the registration terminal 10 transmits the registration request for the device D to the registration operation information holding unit 22 of the device monitoring apparatus 2. (Step S2). The device D registration request includes the device information of the device D input by the user.

Next, since the received device information indicates that the model of the device D is the model D, the registered operation information retaining unit 22 extracts the model D operation correspondence table from the retained operation correspondence table. . Subsequently, the registration operation information holding unit 22 selects the content of any registration operation from the extracted operation correspondence table, the assumed power consumption pattern associated with the content of the selected registration operation, and the device D The content of the registration operation selected as the content of the registration operation is transmitted to the registration operation guidance generation unit 23 (step S3). Subsequently, the registration operation information holding unit 22 transmits an assumed power consumption pattern associated with the content of the registration operation selected in the operation correspondence table to the power consumption pattern matching unit 24 (step S4). Subsequently, the registration operation information holding unit 22 transmits the received device information of the device D to the device information registration unit 25 (step S5).

Note that the operations in steps S3 to S5 after the operation correspondence table extraction by the registered operation information holding unit 22 may be performed simultaneously, or may be performed in a different order from that described above.

Next, the registration operation guidance generation unit 23 sets the execution timing for executing the registration operation content of the device D transmitted from the registration operation information holding unit 22. Subsequently, the registration operation guide generation unit 23 generates a registration operation guide for the device D including the set execution timing and the content of the registration operation for the device D transmitted from the registration operation information holding unit 22 (step S6). .

Next, the registration operation guide generation unit 23 transmits the generated registration operation guide for the device D to the registration terminal 10 (step S7). Subsequently, the registration operation guidance generation unit 23 transmits a power pattern designation timing based on the set execution timing and the time length of the assumed power consumption pattern associated with the content of the registration operation of the device D to the power information collection unit 21. (Step S8).

It should be noted that the operations in steps S7 to S8 after the registration operation guide generation by the registration operation guide generation unit 23 may be performed simultaneously or in an order different from that described above.

Next, the registration terminal 10 presents the contents of the registration operation guidance of the device D transmitted from the registration operation guidance generation unit 23 to the user by text, images, voice, or the like (step S9). For example, if the selected registration operation is “Power on” and the set execution timing is one minute later, the registration terminal 10 will “power on device D after one minute. To the user. The user who has received the presentation performs the registration operation of the content indicated by the registration operation guide on the device D at the execution timing indicated by the registration operation guide (step S10).

At this time, the power information collection unit 21 collects the power consumption measurement results from each of the smart sockets SS1 to SS4 (step S11), and each of the smart sockets SS1 to SS4 during the period based on the power pattern designation timing. The measured power consumption pattern is derived for each of the smart sockets SS1 to SS4 based on the measurement result of the power consumption measured by, and the derived measured power consumption pattern is transmitted to the power consumption pattern matching unit 24 (step S12).

Next, the power consumption pattern matching unit 24 performs matching between the actually measured power consumption pattern transmitted from the power information collecting unit 21 and the assumed power consumption pattern transmitted from the registered operation information holding unit 22, thereby assuming the assumed power consumption pattern. The actually measured power consumption pattern that matches with is specified (step S13). Thereby, the power consumption pattern matching unit 24 can specify the smart socket SS4 that has transmitted the actually measured power consumption pattern that matches the assumed power consumption pattern.

For example, let us consider a case where the actually measured power consumption patterns shown in FIGS. 4A to 4D are derived and the assumed power consumption pattern shown in FIG. 4E is transmitted. In this case, the power consumption pattern matching unit 24 matches the patterns (a) to (d) in FIG. 4 with the pattern (e) in FIG. 4 to obtain the pattern (d) in FIG. Identify. In this pattern matching, for example, based on the pattern of FIG. 4 (e) as a reference, the pattern matching is performed depending on whether a plurality of coordinates of each pattern of FIG. 4 (a) to (d) exist within a predetermined error range such as 10%. Is called.

Next, the power consumption pattern matching unit 24 transmits the identification information of the identified smart socket SS4 to the device information registration unit 25 (step S14).

Next, the device information registration unit 25 associates the identification information of the smart socket SS4 transmitted from the power consumption pattern matching unit 24 with the device information of the device D transmitted from the registered operation information holding unit 22, and corresponds to the device. Register in the table (step S15).

Next, the device information registration unit 25 transmits a device registration result indicating that the device information of the device D and the identification information of the smart socket SS4 are registered in the EMS 1 to the registration terminal 10 (step S16). The registration terminal 10 presents the contents of the device registration result of the device D transmitted from the device information registration unit 25 to the user by text, an image, or voice (step S17).

As described above, the device monitoring device 2 of the EMS 1 of the present embodiment is a device that monitors the power consumption of registered devices, and the device A connected from the smart sockets SS1 to SS4 to the smart sockets SS1 to SS4. A power information collecting unit 21 that collects measured power consumption patterns measured for .about.D is provided. The device monitoring apparatus 2 further includes a registration operation information holding unit that holds the content of the registration operation performed on the device D when registering the device D and the assumed power consumption pattern of the device D generated by the registration operation in association with each other. 22. In addition, when receiving a registration request for requesting registration of the device D, the device monitoring apparatus 2 performs the registration request on the device D having the registration request among the contents of the registration operation held by the registration operation information holding unit 22. A registration operation guide in which the content of the registration operation is associated with the execution timing of the content of the registration operation of the device D that has requested registration is generated, and the expected power consumption pattern is determined from the time (time) indicated by the execution timing. A registration operation guidance generation unit 23 is provided that transmits the power pattern designation timing indicated by the period corresponding to the time length to the power information collection unit 21. In addition, the device monitoring apparatus 2 further includes a power pattern designation timing (execution timing indicated by the registration operation guide generated by the registration operation guide generation unit 23 and registration operation indicated by the registration operation guide generated by the registration operation guide generation unit 23. The registration operation indicated by the registered operation guide generated by the registered operation guide generator 23 and the actually measured power consumption pattern measured by the smart sockets SS1 to SS4 during the period based on the time length of the power consumption pattern of the device generated by The power consumption pattern collating unit 24 that identifies the smart socket SS4 to which the device D requested to be registered is collated with the assumed power consumption pattern associated with the content of In addition, the device monitoring apparatus 2 further includes a device information registration unit 25 that registers the smart socket SS4 specified by the power consumption pattern matching unit 24 and the device D that has requested registration in association with each other. Thus, the user does not need to perform a complicated registration operation, and the device monitoring apparatus 2 automatically identifies the smart socket SS4 connected to the device D for which registration is requested, and the device D for which registration is requested. Register in association. As a result, since the device D and the smart socket SS4 can be registered in association with each other accurately, the power consumption of the devices A to D can be accurately monitored by the device monitoring device 2.

Further, in the present embodiment, the registration operation information holding unit 22 holds the contents of a plurality of different registration operations. Therefore, if the registered operation guidance generation unit 23 cannot identify the smart socket SS4 in the matching with the assumed power consumption pattern in the power consumption pattern matching unit 24 (when the identification of the smart socket (SS4) fails), the registration operation guidance generation unit 23 You may generate | occur | produce the new registration operation guidance containing the content of the registration operation different from the content of the registration operation matched with the assumption power consumption pattern used for the matching which failed in specification of socket SS4. Then, the power consumption pattern matching unit 24 indicates the power pattern designation timing newly transmitted by the registration operation guidance generating unit 23 to the power consumption pattern matching unit 24 (the new registered operation guidance generated by the registration operation guidance generating unit 23 indicates Actual measurement measured by the smart sockets SS1 to SS4 during a period based on the execution timing and the time length of the power consumption pattern of the device generated by the registration operation indicated by the new registration operation guide generated by the registration operation guide generation unit 23 The device D that has requested registration is connected by comparing the power consumption pattern with the assumed power consumption pattern associated with the content of the registration operation indicated by the new registration operation guide generated by the registration operation guide generation unit 23. The identified smart socket SS4 may be specified. Thereby, when the smart socket to which the device D is connected cannot be specified as the smart socket SS4 and the registration of the device D fails, the registration operation is performed again with a registration operation guide different from the failed registration operation guide. be able to.

Moreover, in this Embodiment, although it was able to narrow down to several smart sockets in matching with the assumed power consumption pattern of the power consumption pattern collation part 24, it was not able to specify to one smart socket (SS4). In the case (when the identification of the smart socket (SS4) fails), when the registration operation of the device D is performed again, the power consumption pattern matching unit 24 selects the smart socket (the failed matching) that has been narrowed down in the previous matching. The smart power sockets narrowed down in FIG. 5 are again associated with the measured power consumption pattern based on the measured power consumption measurement result and the content of the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit 23. The device D that requested registration is connected by matching the assumed power consumption pattern. It may identify the smart socket SS4. Thereby, the range of the smart socket to be specified can be narrowed, and the smart socket SS4 can be specified with high accuracy.

(Modification 1 of Embodiment 1)
Next, the configuration of the EMS 1 according to the first modification of the first embodiment will be described with reference to FIG. FIG. 5 is a block diagram showing a schematic configuration of the EMS 1 according to this modification.

In the device monitoring apparatus 2 of the EMS 1 of the first embodiment, the power consumption pattern matching unit 24 performs pattern matching using the assumed power consumption pattern transmitted from the registered operation information holding unit 22 as it is. However, for example, current sensors built in smart sockets have different characteristics depending on the model, so that the power consumption (measured power consumption pattern) measured by the smart socket may vary depending on the smart socket model. The characteristics of the current sensor include, for example, a coupling coefficient (K value: ideal is K = 1) characteristic indicating a ratio of a difference between an ideal value and an actual measurement value at a measurement point. Therefore, as shown in FIG. 5, the device monitoring apparatus 2 of the present modified example consumes between the registered operation information holding unit 22 and the power consumption pattern matching unit 24 with respect to the device monitoring apparatus 2 of the first embodiment. A power pattern correction unit 28a is provided to correct the assumed power consumption pattern. Hereinafter, the differences from the EMS 1 of the first embodiment will be mainly described.

The device monitoring apparatus 2 includes a power information collecting unit 21, a registered operation information holding unit 22, a registered operation guidance generating unit 23, a power consumption pattern matching unit 24, a device information registering unit 25, and a power consumption pattern correcting unit 28a. With.

The registration operation information holding unit 22 selects the content of any registration operation from the extracted operation correspondence table when registering the device in the EMS 1. Then, the registration operation information holding unit 22 transmits the content of the selected registration operation and the assumed power consumption pattern associated with the content of the registration operation to the registration operation guidance generation unit 23 and the registration selected in the operation correspondence table. The assumed power consumption pattern associated with the content of the operation is transmitted to the power consumption pattern correction unit 28a.

When registering the device in the EMS 1, the power consumption pattern correction unit 28a corrects the assumed power consumption pattern transmitted from the registration operation information holding unit 22 according to the model of the smart socket, and obtains the corrected assumed power consumption pattern. It transmits to the power consumption pattern matching unit 24. Therefore, when the models of the smart sockets SS1 to SS4 are different from each other, the assumed power consumption pattern is corrected according to the model of the smart socket, and a plurality of corrected assumed power consumption patterns are transmitted to the power consumption pattern matching unit 24. . The assumed power consumption pattern is corrected by, for example, the assumed power consumption transmitted from the registered operation information holding unit 22 based on a correction value based on the smart socket model such as the coupling coefficient of the current sensor of the smart socket from which the assumed power consumption pattern is obtained. This is done by correcting the pattern. For example, when the coupling coefficient of the current sensor is used as the correction value, the assumed power consumption pattern is multiplied by the coupling coefficient.

In this case, the correction value may be held in the power consumption pattern correction unit 28a for each smart socket model, but the correction value for each assumed power consumption pattern and each smart socket model is stored in the operation correspondence table. The registered operation information holding unit 22 may hold the information in association with the assumed power consumption pattern. In this case, the power consumption pattern correction unit 28a transmits the correction value for each model of the smart socket associated with the assumed power consumption pattern.

When the power consumption pattern matching unit 24 registers the device in the EMS 1, the actual power consumption pattern transmitted from the power information collection unit 21, and the corrected estimated power consumption pattern transmitted from the power consumption pattern correction unit 28a. Perform matching. At this time, as the corrected assumed power consumption pattern used for matching with the actually measured power consumption pattern, the assumed power consumption pattern corrected according to the model of the smart socket that has measured the actually measured power consumption pattern is used. Then, as a result of pattern matching, the power consumption pattern matching unit 24 identifies the smart socket that has transmitted the actually measured power consumption pattern that matches the corrected estimated power consumption pattern, thereby connecting the smart device connected to the device that has requested registration. Identify the socket.

As described above, according to the EMS 1 of this modification, the power consumption of the devices A to D can be accurately monitored by the device monitoring device 2 for the same reason as the EMS 1 of the first embodiment.

Further, according to the EMS 1 of the present modification, the device monitoring apparatus 2 further includes the power consumption pattern correction unit 28 a that corrects the assumed power consumption pattern held by the registered operation information holding unit 22. Then, in the pattern matching, the power consumption pattern matching unit 24 matches the assumed power consumption pattern corrected by the power consumption pattern correction unit 28a with the actually measured power consumption pattern collected by the power information collecting unit 21. Thereby, for example, the assumed power consumption pattern is corrected in consideration of variations depending on the type of smart socket, so that the smart socket SS4 connected to the device D requested to be registered in the pattern matching can be accurately specified.

Note that, in the EMS 1 of this modification, by providing the power consumption pattern correction unit 28a, the variation due to the smart socket in the assumed power consumption pattern is suppressed, and the accuracy of pattern matching is improved. However, the configuration of the EMS 1 is the same as that shown in FIG. 1A, and in the operation correspondence table, by associating a plurality of assumed power consumption patterns corresponding to the smart socket models with the content of one registration operation, The accuracy may be improved. In this case, the registered operation information holding unit 22 associates the assumed power consumption pattern to be held with the smart socket model. In the pattern matching, the power consumption pattern matching unit 24 determines the actual power consumption pattern collected by the power information collection unit 21 and the smart socket model from which the actual power consumption pattern collected by the power information collection unit 21 is obtained. The assumed power consumption pattern matched with the content of the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit 23 is matched. At this time, the model of the smart socket is information specifying the type of the smart socket such as the manufacturer name of the smart socket and the model number of the smart socket.

In this configuration, in step S4 of FIG. 3, the registered operation information holding unit 22 transmits a plurality of assumed power consumption patterns associated with the contents of the registration operation selected in the operation correspondence table to the power consumption pattern matching unit 24. . In step S13 of FIG. 3, the power consumption pattern matching unit 24 is associated with the model of the smart socket that has transmitted the actually measured power consumption pattern from the plurality of assumed power consumption patterns transmitted from the registered operation information holding unit 22. Pattern matching is performed after extracting the assumed power consumption pattern. Accordingly, the power consumption pattern matching unit 24 uses, for example, an assumed power consumption pattern associated with the smart socket SS4 in the operation correspondence table in matching with the actually measured power consumption pattern from the smart socket SS4. And the power consumption pattern collation part 24 uses the assumed power consumption pattern matched with smart socket SS3 by the operation corresponding | compatible table, for example in the matching of the measurement power consumption pattern from smart socket SS3.

(Modification 2 of Embodiment 1)
Next, the structure of EMS1 which concerns on the modification 2 of Embodiment 1 is demonstrated using FIG. FIG. 6 is a block diagram showing a schematic configuration of the EMS 1 according to this modification.

In the device monitoring apparatus 2 of the EMS 1 of the first embodiment, the power consumption pattern matching unit 24 performs pattern matching using the measured power consumption pattern transmitted from the power information collecting unit 21 as it is. However, for example, current sensors built in smart sockets have different characteristics depending on the model, so that the power consumption (measured power consumption pattern) measured by the smart socket may vary depending on the smart socket model. Therefore, as shown in FIG. 6, the device monitoring apparatus 2 according to the present modification has a power consumption between the power information collecting unit 21 and the power consumption pattern matching unit 24 compared to the device monitoring apparatus 2 according to the first embodiment. A pattern correction unit 28b is provided to correct the measured power consumption pattern. Hereinafter, the differences from the EMS 1 of the first embodiment will be mainly described.

The device monitoring apparatus 2 includes a power information collecting unit 21, a registered operation information holding unit 22, a registered operation guidance generating unit 23, a power consumption pattern matching unit 24, a device information registering unit 25, and a power consumption pattern correcting unit 28b. With.

The power information collection unit 21 transmits the measured power consumption pattern derived for each of the smart sockets SS1 to SS4 to the power consumption pattern correction unit 28b when the device is registered in the EMS1.

The power consumption pattern correction unit 28b corrects the actually measured power consumption pattern transmitted from the power information collection unit 21 when the device is registered in the EMS 1 and transmits the corrected actual power consumption pattern to the power consumption pattern matching unit 24. To do. The correction of the actual measured power consumption pattern is performed by correcting the collected actual measured power consumption pattern with a correction value based on the smart socket model such as the coupling coefficient of the smart socket current sensor from which the actual measured power consumption pattern was obtained. . For example, when the coupling coefficient of the current sensor is used as the correction value, the coupling coefficient is divided into the actually measured power consumption pattern.

In this case, the power consumption pattern correction unit 28b holds a correction value in association with the smart socket model.

When the power consumption pattern matching unit 24 registers the device in the EMS 1, the corrected actual power consumption pattern transmitted from the power consumption pattern correction unit 28 b and the assumed power consumption pattern transmitted from the registered operation information holding unit 22. Match with. Then, as a result of pattern matching, the power consumption pattern matching unit 24 identifies the corrected actual measured power consumption pattern that matches the assumed power consumption pattern, and identifies the smart socket that transmitted the uncorrected one. Identify the smart socket connected to the affected device.

Further, according to the EMS 1 of the present modification, the device monitoring apparatus 2 further includes the power consumption pattern correction unit 28b that corrects the actually measured power consumption pattern collected by the power information collection unit 21. Then, the power consumption pattern matching unit 24 performs the actual power consumption pattern corrected by the power consumption pattern correction unit 28b and the contents of the registration operation indicated by the registration operation guide generated by the registration operation guide generation unit 23 in the pattern matching. Matching with the assumed power consumption pattern associated. As a result, for example, the measured power consumption pattern is corrected in consideration of variations depending on the type of smart socket, so that the smart socket SS4 connected to the device D requested to be registered in pattern matching can be accurately specified.

(Modification 3 of Embodiment 1)
Next, the structure of EMS1 which concerns on the modification 3 of Embodiment 1 is demonstrated using FIG. FIG. 7 is a flowchart showing the flow of the device registration operation guidance generation process (step S6) in the EMS 1 according to this modification.

In the device monitoring apparatus 2 of the EMS 1 according to the first embodiment, it is assumed that when there is a registration request for the device D, there is no registration request for another device. The configuration of Form 1 is applicable. However, the model of another device that has already been requested for registration is the same model D as the device D, and a registration operation guide having the same content as the other devices may be generated in the registration operation guide of the device D. In this case, since the same actually measured power consumption pattern is obtained from the device D and other devices at the same time, the device D cannot be registered separately from the other devices. Therefore, as shown in FIG. 7, the device monitoring apparatus 2 of the present modification is different from the device monitoring apparatus 2 according to the first embodiment in that the registration operation guide generation unit 23 is connected to other devices already requested for registration. In consideration of whether or not the device D is the same model, a registration operation guide for the device D is generated. Hereinafter, the differences from the EMS 1 of the first embodiment will be mainly described.

In generating a registration operation guide for the device D, the registration operation guide generation unit 23 first registers a device other than the device D of the same model as the device D before setting the execution timing of the registration operation guide for the device D. Whether or not is performed is determined (step S31).

Next, when it is determined that registration processing of another device of the same model as the device D has not been performed (No in step S31), the registration operation guidance generation unit 23 considers registration operation guidance of other devices. The execution timing of the registration operation guidance for the device D is arbitrarily set without any change. In this case, the registration operation guidance generating unit 23 sets the execution timing of the registration operation guidance for the device D at the same execution timing as the registration operation guidance for other devices other than the device D of the same model as the device D. You can also. Subsequently, the registration operation guide generation unit 23 generates a registration operation guide for the device D including the set execution timing and the content of the registration operation for the device D transmitted from the registration operation information holding unit 22 (step S32). .

On the other hand, when it is determined that registration processing of another device of the same model as the device D is being performed (Yes in step S31), the registration operation guidance generation unit 23 performs the execution timing of the registration operation guidance of the device D as An execution timing different from the execution timing of registration operation guidance for other devices is set. Specifically, the registration operation guidance for other devices is executed with a sufficient interval so that the power pattern designation timing in the registration process of device D and the power pattern designation timing in the registration processing of other devices do not overlap. Set an execution timing different from the timing.

Subsequently, the registration operation guide generation unit 23 generates a registration operation guide for the device D including the set execution timing and the content of the registration operation for the device D transmitted from the registration operation information holding unit 22 (step S33). .

Further, according to the EMS 1 of the present modification, the registration operation guide generation unit 23 receives a registration request for a plurality of devices of the same type, and each of a plurality of registration operation guides generated corresponding to the plurality of devices. A plurality of registration operation guides are generated so as to include different execution timings. Thus, even when a plurality of devices of the same type are registered at the same time, the contents of the registration operation are executed at different execution timings, so that a plurality of devices can be registered separately.

(Modification 4 of Embodiment 1)
Next, the structure of EMS1 which concerns on the modification 4 of Embodiment 1 is demonstrated using FIG. FIG. 8 is a flowchart showing the flow of a transmission process (step S3) of the content of the registration operation of the device and the assumed power consumption pattern associated with the content of the registration operation in the EMS 1 according to the present modification.

In the device monitoring apparatus 2 of the EMS 1 according to the third modification of the first embodiment, when another device that has already been requested for registration and the device D are the same model, the execution is different from the execution timing of the registration operation guidance for the other device. The timing registration operation guide is generated as the registration operation guide for the device D. However, adjusting the contents of the registration operations of the both can achieve the same effect as adjusting the execution timing of the registration operation guidance described above. Therefore, as shown in FIG. 8, the device monitoring device 2 of the present modified example is different from the device monitoring device 2 according to the first embodiment in that the registration operation information holding unit 22 is different from other devices already requested for registration. The contents of the registration operation different from those of the device D are selected and transmitted. However, in this case, the registration operation information holding unit 22 registers the content of the registration operation that allows the power consumption pattern to be distinguished because the time variation of the power consumption differs depending on the content of the registration operation even if the model is the same. It shall be. Hereinafter, the differences from the EMS 1 of the first embodiment will be mainly described.

In transmitting the contents of the registration operation of the device D, the registration operation information holding unit 22 first performs registration processing of a device other than the device D of the same model as the device D before setting the content of the registration operation of the device D. It is determined whether or not it has been performed (step S41).

Next, when it is determined that registration processing of another device of the same model as the device D has not been performed (No in step S41), the registration operation information holding unit 22 considers the contents of the registration operation of other devices. The contents of the registration operation of the device D are arbitrarily selected without doing so. In this case, the registration operation information holding unit 22 can select the same registration operation content as the registration operation content of the other device as the registration operation content of the device D. Subsequently, the registration operation information holding unit 22 transmits the content of the registration operation of the selected device D and the assumed power consumption pattern associated with the content of the registration operation to the registration operation guidance generation unit 23 (step S42).

On the other hand, if it is determined that registration processing of another device of the same model as the device D is being performed (Yes in step S41), the registration operation information holding unit 22 performs registration different from the content of the registration operation of other devices. Select the content of the operation. Subsequently, the registration operation information holding unit 22 transmits the registration operation content of the selected device D and the assumed power consumption pattern associated with the registration operation content to the registration operation guidance generation unit 23 (step S43).

Further, according to the EMS 1 of the present modification, the registration operation information holding unit 22 holds the contents of a plurality of different registration operations. When the registration operation guide generation unit 23 receives a registration request for a plurality of devices of the same type, each of the plurality of registration operation guides generated corresponding to the plurality of devices includes different contents of the registration operation. A plurality of registration operation guides are generated. Thereby, even when registering a plurality of devices of the same type at the same time, the contents of the registration operation are different, so that a plurality of devices can be registered separately.

(Embodiment 2)
Next, the configuration of the EMS 3 according to the second embodiment will be described with reference to FIG. FIG. 9 is a block diagram showing a schematic configuration of the EMS 3 according to the present embodiment.

As shown in FIG. 9, when the EMS 3 registers a device in the EMS 3, the address (IP address) of the device to be registered based on the communication pattern on the device's LAN (Local Area Network) 11 ) Is different from the EMS 1 of the first embodiment. Therefore, the device monitoring apparatus 4 is added with a network information collecting unit 26 and a communication pattern matching unit 27 as a configuration for specifying the IP address of the device with respect to the device monitoring apparatus 2 of the first embodiment. Hereinafter, the differences from the EMS 1 of the first embodiment will be mainly described.

The EMS 3 includes a registration terminal 10, a plurality of smart sockets SS1 to SS4, a device monitoring device 4, and a LAN 11, and monitors the power consumption of the devices A to D. The EMS 3 is, for example, a HEMS that manages a plurality of devices A to D as home appliances. The EMS 3 performs various operations for reducing the power consumption of the devices A to D through data communication with the devices A to D via the LAN 11 based on the monitoring results of the power consumption of the devices A to D.

The LAN 11 is an example of a wireless or wired local area communication network, and connects the devices A to D and the device monitoring device 4 in a state where data communication is possible.

The device monitoring device 4 monitors the power consumption of the devices A to D based on the measurement results of the power consumption by the smart sockets SS1 to SS4, and performs data communication with the devices A to D via the LAN 11 to obtain the monitoring result. Based on this, the controller performs various operations for reducing the power consumption of the devices A to D. The device monitoring apparatus 4 includes a power information collecting unit 21, a registered operation information holding unit 22, a registered operation guidance generating unit 23, a power consumption pattern matching unit 24, a device information registering unit 25, and a network information collecting unit 26. The communication pattern matching unit 27 is provided.

The registration operation information holding unit 22 holds an operation correspondence table provided for each of the models A to D, and when receiving a device registration request from the registration terminal 10 when registering a device in the EMS 3, the registration operation information is received. Operation correspondence table for the model of the selected device. In the operation correspondence table, as shown in FIG. 10A, a plurality of registration operation contents for the device are registered, and the contents of each registered operation include the assumed power consumption pattern of the device by the registration operation, A communication message sequence (assumed communication pattern) on the LAN 11 by the registration operation is associated. For example, in the operation correspondence table provided for the model A, “power activation” is registered as the content of the registration operation of the model A device, and the predetermined assumed power consumption pattern and power activation at the time of power activation of the model A device are displayed. It is registered in association with the assumed communication pattern at the time of raising. Note that the content of the registration operation in the operation correspondence table includes the content of communication messages and the order of communication messages generated by the device on which the registration operation has been performed, the content of communication messages of other devices and the order of communication messages. It is preferable that the contents of the registration operation that can be distinguished are registered.

The registration operation information holding unit 22 selects content of any registration operation from the extracted operation correspondence table when registering a device in the EMS 3. Then, the registration operation information holding unit 22 transmits the content of the selected registration operation and the assumed power consumption pattern and the assumed communication pattern associated with the content of the selected registration operation to the registration operation guidance generation unit 23, and the operation The assumed power consumption pattern associated with the content of the registration operation selected in the correspondence table is transmitted to the power consumption pattern matching unit 24. Also, the registered operation information holding unit 22 transmits an assumed communication pattern associated with the content of the registered operation selected in the operation correspondence table to the communication pattern matching unit 27.

The registration operation guide generation unit 23 generates a registration operation guide including the execution timing, transmits the registration operation guide to the registration terminal 10, and further, from the time (time) indicated by the execution timing to the period corresponding to the time length of the assumed power consumption pattern Is transmitted to the power information collection unit 21, and the communication pattern designation timing indicating the period corresponding to the time length of the assumed communication pattern from the time (time) indicated by the execution timing to the network information collection unit 26. Send.

The network information collection unit 26 is an acquisition unit that acquires communication messages of the devices A to D on the LAN 11, and always collects communication messages on the LAN 11.

The network information collection unit 26 derives communication messages (measured communication patterns) on the LAN 11 collected during a period based on the communication pattern designation timing received by the registration operation guide generation unit 23 when the device is registered in the EMS 3. And transmitted to the communication pattern matching unit 27. In this transmission, in order to be able to identify which of the devices A to D each communication message is, the communication message is transmitted in association with the IP address (MAC address) of the device that transmitted the communication message. .

The communication pattern matching unit 27 performs matching between the actually measured communication pattern transmitted from the network information collecting unit 26 and the assumed communication pattern transmitted from the registered operation information holding unit 22 when the device is registered in the EMS 3. Specifically, in the matching, a communication message included in the assumed communication pattern is searched from communication messages in the actually measured communication pattern, and a device that performs communication is specified in accordance with a communication message sequence indicated by the assumed communication pattern. And the communication pattern collation part 27 specifies the IP address of the apparatus which requested | required registration by specifying the apparatus which communicated with the measured communication pattern which matches an assumption communication pattern as a result of pattern matching. Then, the power consumption pattern matching unit 24 transmits the identified IP address to the device information registration unit 25.

The device information registration unit 25 holds a device correspondence table in which a plurality of correspondence relationships between device information, smart socket identification information, and IP addresses are registered. When the device information registration unit 25 registers the device in the EMS 3, the smart socket identification information transmitted from the power consumption pattern matching unit 24 and the registration operation information storage unit 22 are transmitted to the device correspondence table held by the device information registration unit 25. Device information and the IP address transmitted from the communication pattern matching unit 27 are registered in association with each other. For example, in the device correspondence table, as shown in FIG. 10B, the device information of the device A is registered in association with the identification information of the smart socket SS1 and the IP address A1.

Next, a device registration process flow in the EMS 3 according to the second embodiment will be described. FIG. 11 is a sequence diagram showing a flow of device registration processing in the EMS 3 according to the present embodiment. In the description of FIG. 11, the flow of processing for registering the device D in the EMS 3 is described assuming that the device D is not registered in the EMS 3, but the same processing is performed in the registration of other devices. In FIG. 11, processing different from that in the other embodiments is indicated by a broken-line frame.

As shown in FIG. 11, first, when the registration terminal 10 receives a registration request for the device D from the user (step S <b> 1), the registration terminal 10 sends the registration request for the device D to the registration operation information holding unit 22 of the device monitoring apparatus 4. Transmit (step S2).

Next, since the device information included in the received registration request indicates that the model of the device D is the model D, the registered operation information holding unit 22 operates the model D from the held operation correspondence table. Extract correspondence table. Subsequently, the registration operation information holding unit 22 selects any registration operation content from the extracted operation correspondence table, and assumes an assumed power consumption pattern and an assumed communication pattern associated with the selected registration operation content. Then, the content of the registration operation selected as the content of the registration operation of the device D is transmitted to the registration operation guidance generating unit 23 (step S19). Subsequently, the registration operation information holding unit 22 transmits an assumed power consumption pattern associated with the content of the registration operation selected in the operation correspondence table to the power consumption pattern matching unit 24 (step S4). Subsequently, the registration operation information holding unit 22 transmits an assumed communication pattern associated with the content of the registration operation selected in the operation correspondence table to the communication pattern matching unit 27 (step S20). Subsequently, the registration operation information holding unit 22 transmits the received device information of the device D to the device information registration unit 25 (step S5).

Note that the operations of steps S3 to S5 and S20 after the operation correspondence table extraction by the registered operation information holding unit 22 may be performed simultaneously, or may be performed in a different order from that described above.

Next, the registration operation guide generation unit 23 transmits the generated registration operation guide for the device D to the registration terminal 10 (step S7). Subsequently, the registration operation guidance generation unit 23 transmits a power pattern designation timing based on the set execution timing and the time length of the assumed power consumption pattern associated with the content of the registration operation of the device D to the power information collection unit 21. At the same time (step S8), the communication pattern designation timing based on the set execution timing and the time length of the assumed communication pattern associated with the contents of the registration operation of the device D is transmitted to the network information collecting unit 26 (step S21). .

It should be noted that the operations of steps S7 to S8 and S21 after the registration operation guide generation by the registration operation guide generation unit 23 may be performed simultaneously or in a different order from that described above.

Next, the registration terminal 10 presents the contents of the registration operation guidance of the device D transmitted from the registration operation guidance generation unit 23 to the user by text and images, and further by voice (step S9). The user who has received the presentation performs a registration operation of the content indicated in the registration operation guide on the device D at the execution timing indicated in the registration operation guide (step S10).

At the same time, the network information collection unit 26 collects communication messages on the LAN 11 (step S22), and derives and derives an actually measured communication pattern based on the communication messages collected during the period based on the communication pattern designation timing. All measured communication patterns are transmitted to the communication pattern matching unit 27 (step S23).

Further, the communication pattern matching unit 27 performs matching between the actual communication pattern transmitted from the network information collecting unit 26 and the assumed communication pattern transmitted from the registered operation information holding unit 22 and matches the assumed communication pattern. A pattern is specified (step S24). Thereby, the communication pattern collation part 27 can specify the IP address of the apparatus D which communicated with the actual measurement communication pattern which matches an assumption communication pattern.

For example, consider a case where the device D supports UPnP (Universal Plug and Play) and the content of the registration operation is power-up. In this case, the device D executes a service discovery sequence based on SSDP (Simple Service Discovery Protocol) when the power is turned on. Accordingly, the communication pattern matching unit 27 broadcasts a search request (M-SEARCH) message from the device to the multicast address, and connects to the LAN 11 that has received the search request, for example, a device (such as a router not shown in the figure). ), A device information (DDD) acquisition request message is transmitted from the device that has received the search response message to the other device, and device information from the other device that has received the device information (DDD) acquisition request message ( DDD) The device that communicates in the message sequence is identified as device D, and the IP address of device D that has transmitted a message such as a search request (M-SEARCH) is identified.

Also, consider a case in which device D supports DHCP (Dynamic Host Configuration Protocol) and the content of the registration operation is power-up. In this case, the device D obtains an IP address by executing a DHCP-based sequence with a DHCP server (for example, a router not shown in the figure has a DHCP server function) upon power-up. To perform the operation. Accordingly, the communication pattern matching unit 27 transmits the DISCOVER packet from the device to the DHCP server, the response of the OFFER packet from the DHCP server that has received the DISCOVER packet, and the REQUEST packet from the device that has received the response of the OFFER packet to the DHCP server. The device that communicates with the sequence of the PACK response from the DHCP server that has transmitted and received the REQUEST packet is identified as the device D, and the IP address acquired by the device D is identified by DHCP.

Next, the power consumption pattern matching unit 24 transmits the identification information of the identified smart socket SS4 to the device information registration unit 25 (step S14), and the communication pattern matching unit 27 sends the IP address of the identified device D to the device information registration unit. 25 (step S25).

Next, the device information registration unit 25 includes the identification information of the smart socket SS4 transmitted from the power consumption pattern matching unit 24, the device information of the device D transmitted from the registered operation information holding unit 22, and the communication pattern matching unit 27. Is registered in the device correspondence table in association with the IP address of the device D transmitted from (step S15).

Next, the device information registration unit 25 transmits to the registration terminal 10 a device registration result indicating that the device information of the device D, the identification information of the smart socket SS4, and the IP address of the device D are registered in the EMS 3 in association with each other. (Step S16). The registration terminal 10 presents the contents of the device registration result of the device D transmitted from the device information registration unit 25 to the user by text and images, and further by voice (step S17).

As described above, according to the EMS 3 of the present embodiment, for the same reason as the EMS 1 of the first embodiment, the power consumption of the devices A to D is accurately monitored by the device monitoring device 4 and the devices are connected via the LAN 11. A to D can be appropriately controlled.

Further, in the device monitoring device 4 of the EMS 3 of the present embodiment, the registration operation information holding unit 22 includes the contents of the registration operation and an assumed communication pattern that occurs on the LAN 11 that connects the device D and the device monitoring device 4 by the registration operation. Are stored in association with each other. The device monitoring apparatus 4 further includes a network information collection unit 26 that collects measured communication patterns on the LAN 11. In addition, the device monitoring apparatus 4 further includes a communication pattern designation timing (execution timing and registration operation indicated by the registration operation guide generated by the registration operation guide generation unit 23) transmitted from the registration operation guide generation unit 23 to the network information collection unit 26. A measured communication pattern collected by the network information collection unit 26 during a period based on a period of time based on a time length of an assumed communication pattern of a device generated by the registration operation indicated by the registration operation guide generated by the guide generation unit 23, and a registration operation guide A communication pattern collating unit that collates the content of the registration operation indicated by the registration operation guide generated by the generating unit 23 with the assumed communication pattern associated with the IP address on the LAN 11 of the device D that has requested registration. 27. Then, the device information registration unit 25 registers the IP address on the LAN 11 specified by the communication pattern matching unit 27 and the device D that has requested registration in association with each other. As a result, the device monitoring apparatus 4 automatically identifies the IP address of the device D for which registration has been requested, and registers it in association with the device D for which registration has been requested. Therefore, the IP address of the device D can be accurately and easily registered, and the communication between the devices A to D and the device monitoring apparatus 4 can be performed accurately in the EMS 3.

The registration operation information holding unit 22 may further hold the operation of the device generated by the registration operation, the communication pattern of the device generated by the registration operation, and the power consumption pattern of the device generated by the registration operation in association with each other. .

For example, in this case, the communication pattern collating unit 27 identifies the device model and operation by collating the communication pattern collected by the network information collecting unit 26 with the communication pattern held by the registered operation information holding unit 22. The power consumption pattern matching unit 24 is a device that is stored in the measured power consumption pattern corresponding to the operation of the device collected by the power information collecting unit 21 and the registered operation information holding unit 22 and specified by the communication pattern matching unit 27. The model of the device connected to the smart socket (or the power line) may be specified by collating with the assumed power consumption pattern corresponding to the operation.

(Modification 1 of Embodiment 2)
Next, the structure of EMS3 which concerns on the modification 1 of Embodiment 2 is demonstrated using FIG. FIG. 12 is a sequence diagram showing a flow of device registration processing in the EMS 3 according to this modification. In the description of FIG. 12, the flow of processing for registering the device D in the EMS 3 will be described assuming that the device D has not been registered in the EMS 3, but similar processing is performed in the registration of other devices. In FIG. 12, processing different from that in the other embodiments is indicated by a broken-line frame.

In the device monitoring device 4 of the EMS 3 of the second embodiment, the user voluntarily issues a registration request for the unregistered device D to the device monitoring device 4 via the registration terminal 10. However, the device monitoring apparatus 4 discovers the unregistered device D and prompts the user to register the device D, thereby avoiding a situation where the device D is left unregistered. Therefore, as shown in FIG. 12, the device monitoring apparatus 4 according to the present modified example has not been registered by the power information collection unit 21 by collecting the power consumption measurement results with respect to the device monitoring apparatus 4 of the second embodiment. It discovers that a device is connected to the smart socket SS4 and prompts the user to register the device D connected thereto. Hereinafter, the difference from the EMS 3 of the second embodiment will be mainly described.

First, the power information collection unit 21 collects power consumption measurement results from the smart socket SS4 (step S30). Subsequently, the power information collection unit 21 determines whether or not a device is registered in the device correspondence table of the device information registration unit 25 regarding the collected smart socket SS4 (step S31). Thereby, the power information collection unit 21 can determine whether the detection result of the power consumption is transmitted from the unregistered smart socket SS4.

Next, when the power information collection unit 21 determines that the device is not registered in the device correspondence table with respect to the smart socket SS4, the power information collection unit 21 transmits a message for urging registration of the device D connected to the smart socket SS4 to the registration terminal 10 ( Step S32). Upon receiving the message, the registration terminal 10 presents the content of the message to the user by text and images, and further by voice (step S33).

Next, the same processing of steps S1 to S25 as in FIG. 11 is performed. However, it is specified that the smart socket to which the device D that has received the registration request is connected is the smart socket SS4. Accordingly, in step S12, the power information collection unit 21 derives an actually measured power consumption pattern for only the smart socket SS4.

As described above, according to the EMS 3 of the present modification, the power consumption of the devices A to D can be accurately monitored by the device monitoring device 4 for the same reason as the EMS 1 of the first embodiment.

Moreover, according to EMS3 of this modification, when the device collects the power consumption pattern from the unregistered smart socket SS4, the power information collection unit 21 registers the device D connected to the unregistered smart socket SS4. Output a prompt message. As a result, the device monitoring apparatus 4 automatically discovers the unregistered device D and prompts the user to register it, thereby preventing the device D from being left unregistered.

(Modification 2 of Embodiment 2)
Next, the structure of EMS3 which concerns on the modification 2 of Embodiment 2 is demonstrated using FIG. FIG. 13 is a sequence diagram showing a flow of device registration processing in the EMS 3 according to this modification. In FIG. 13, processing different from that in the other embodiments is indicated by a broken-line frame.

In the device monitoring apparatus 4 of the EMS 3 according to the second embodiment, the correspondence relationship between the device and the smart socket may change due to changing the installation location of the device or replacing the device. In this case, if the user recognizes the change in the correspondence relationship and does not update the correspondence relationship, the power consumption of the device continues to be erroneously monitored. For example, two different devices connected to two different smart sockets may be exchanged, or another new device may be connected to a smart socket in which devices are already registered. Therefore, in the device monitoring apparatus 4 of this modification, as shown in FIG. 13, the power information collection unit 21 detects a change in the correspondence between the device and the smart socket, compared to the device monitoring apparatus 4 of the second embodiment. Therefore, it prompts the user to re-register the device whose correspondence has changed. Hereinafter, the difference from the EMS 3 of the second embodiment will be mainly described.

In the description of FIG. 13, if a device different from the device D is connected to the smart socket SS4, it is registered in the EMS 3, and the device D newly connected to the smart socket SS4 is not registered in the EMS 3. Assuming that there is a flow of processing for registering the device D in the EMS 3 again, the same processing is performed for registration of other devices.

First, the power information collection unit 21 collects the measurement result of power consumption from the smart socket SS4 (step S40), derives the actual measurement power consumption pattern for the smart socket SS4 based on the collected measurement result of power consumption, and periodically Specifically, the smart socket SS4 is matched with a predetermined power consumption pattern of a device associated with the device correspondence table.

Actually, not only the smart socket SS4 but also the smart sockets SS1 to SS4 whose devices are registered in the device correspondence table are periodically derived from the respective measured power consumption patterns and correlated in the device correspondence table. Matching with a predetermined power consumption pattern of the device being used.

For example, with respect to the power consumption pattern when the power supply is started up rapidly from 0 W, it is determined whether or not the derived actual power consumption pattern matches the power consumption pattern when the predetermined power supply is started. Thereby, the power information collection unit 21 determines whether the correspondence relationship in the device correspondence table is maintained. At this time, in the case of FIG. 13, a power consumption pattern different from that registered for the smart socket SS4 is detected (step S41). In this case, the power information collection unit 21 uses the assumed power consumption pattern registered in the operation correspondence table held in the registered operation information holding unit 22 as a predetermined power consumption pattern for matching with the actually measured power consumption pattern. refer.

Next, the power information collection unit 21 transmits a message for prompting registration of the device D newly connected to the smart socket SS4 to the registration terminal 10 (step S42). Upon receiving the message, the registration terminal 10 presents the content of the message to the user by text and images, and further by voice or the like (step S43).

Further, according to the EMS 3 of the present modification, the power information collection unit 21 uses a device whose measured power consumption pattern collected from the smart socket SS4 in which the device is registered is different from the device registered in association with the smart socket SS4. In the case of the power consumption pattern, a message prompting registration of the device D newly connected to the smart socket SS4 is output. As a result, when the correspondence between the device and the smart socket changes, it is possible to ask the user to register the device whose correspondence has changed. Even in this case, the device monitoring device 4 can accurately determine the power consumption of the device. Can be monitored.

(Modification 3 of Embodiment 2)
Next, the structure of EMS3 which concerns on the modification 3 of Embodiment 2 is demonstrated using FIG. FIG. 14 is a block diagram illustrating a schematic configuration of the EMS 3 according to the present modification.

In the EMS 3 of the second embodiment, the user inputs the device information of the device D to the registration terminal 10 when registering the device D. However, when the registration terminal 10 includes an imaging unit or the like, specifies the model of the device D by image analysis, and inputs the device information of the device D to the registration terminal 10, the device information can be input accurately and easily. Therefore, as shown in FIG. 14, the registration terminal 10 of the present modification includes a device information acquisition unit 12 having an imaging unit or the like that acquires device information with respect to the registration terminal 10 of the second embodiment. . Hereinafter, the difference from the EMS 3 of the second embodiment will be mainly described.

The registration terminal 10 includes an apparatus information acquisition unit 12 including an imaging unit such as a camera and a model specifying unit that specifies a model of the device by image analysis. The model specifying unit holds, for each device type, reference information for analyzing the image obtained by capturing the device and specifying the device model. The device information acquisition unit 12 captures the device D, identifies the model of the device to be imaged by performing image analysis on the captured image, and acquires device information. For example, at this time, the device information can be acquired more accurately by imaging the nameplate portion of the device D on which the model number of the device D is printed. Thereby, it is possible to input the model of the device to be imaged accurately and simply to the registration terminal 10.

Next, the flow of device registration processing in EMS 3 according to Modification 3 of Embodiment 2 will be described. FIG. 15 is a sequence diagram illustrating a flow of device registration processing in the EMS 3 according to the present modification. In the description of FIG. 15, it is assumed that the device D has not been registered in the EMS 3 and the flow of processing for registering the device D in the EMS 3 will be described. However, similar processing is performed in the registration of other devices. In FIG. 15, processing different from that in the other embodiments is indicated by a broken-line frame.

First, the user performs an imaging operation to instruct the registration terminal 10 to image the device D (step S50), and the device information acquisition unit 12 images the device D (step S51). Subsequently, the device information acquisition unit 12 analyzes the captured image and acquires device information (step S52).

Next, the registration terminal 10 transmits a registration request including the device information of the device D acquired by the device information acquisition unit 12 to the registration operation information holding unit 22 of the device monitoring device 4 (step S2).

Next, the same processing of steps S3 to S25 as in FIG. 11 is performed.

Further, according to the EMS 3 of the present modification, the registration terminal 10 includes the imaging unit and the model specifying unit that specifies the model of the device by image analysis, and includes the device information acquisition unit 12 that acquires the device information. The information holding unit 22 identifies the model of the device D based on the device information obtained by imaging the device D by the device information acquisition unit 12. Thereby, apparatus information can be input into the apparatus monitoring apparatus 4 correctly and easily.

In the EMS 3 of this modification, the device D itself to be registered is imaged. However, the warranty card of the device D or a document attached at the time of purchase of the device D is imaged, and the device D printed on them by image analysis is captured. The model number may be specified.

In addition, in the EMS 3 of this modification example, the registration terminal 10 performs the specification of the device type. However, the registration terminal 10 performs the image acquisition, and the device monitoring apparatus 4 acquires the device information by image analysis. It may be broken. In this case, the device monitoring apparatus 4 includes a processing unit corresponding to a model specifying unit.

Further, when the device D has a non-contact IC communication function such as NFC (Near Field Communication), the device information acquisition unit 12 of the registration terminal 10 has a non-contact IC communication unit in the EMS 3 of this modification. Device information may be acquired from the device D by performing non-contact IC communication with the device D. In this case, simply by touching the non-contact IC communication unit of the registration terminal 10 to the non-contact IC communication part of the device D, the device information acquisition unit 12 of the registration terminal 10 acquires the device information of the device D. Thus, the device information can be input to the device monitoring device 4 accurately and easily.

Further, in the EMS 3 of this modification, the device information acquisition unit 12 has a barcode reader, and the device D printed on the barcode indicating the model of the device D attached to the device D, the warranty card of the device D, or the like. The device information of the device to be imaged may be acquired by reading a bar code indicating the type of the device. In this case, the device information acquisition may be performed by the device information acquisition unit 12, or the code information acquired by the device information acquisition unit 12 may be transmitted to the device monitoring device 4 and performed by the device monitoring device 4. .
