That is, the information storage unit 143 has a function of a storage unit, and stores electrical device information (operation condition information) acquired by the acquisition unit 1421 for each electrical device.

  Next, management table creation processing by the power management apparatus 140 will be described with reference to FIG.

  In the power management apparatus 140, when the management unit 142 detects a new connection or reconnection of an electrical device (step S101), the management unit 142 acquires specific electrical device information from the electrical device (step S102), and the time zone, season, etc. A management table is created so as to satisfy the registered operation conditions (step S103).

  The power management apparatus 140 creates a management table corresponding to all connected electrical devices (creates a management table for each electrical device), and relates to electrical devices that are out of operation based on this management table. Notifies the outlet or tap to which the electrical device is connected that the power should be shut off.

  An example of the management table created by the management unit 142 is shown in FIG.

  In this example, in FIG. 1, the electric device 130 # 1 (electric device 1) indicates a computer (PC), the electric device 130 # 2 (electric device 2) indicates a printer, and the electric device 130 # 3 (electric device 3). ) Indicates a television (TV), the electric device 130 # 4 (electric device 4) indicates a lighting device, and the electric device 130 # 5 (electric device 5) indicates a heating device.

  Now, in the management table shown in FIG. 6, the management parameters of each electric device are given in a list. The management table includes items such as month, day of the week, time (24-hour time notation), temperature, operating conditions, connection hierarchy, and electric energy.

  For example, in this management table, “8:00 to 23:00” is registered in the time item and “time” is registered in the operation condition item, corresponding to the electrical device 1 (PC). This means that “8:00 to 23:00” indicates operating condition information (electric device information) related to the use of the electric device 1. In other words, the electrical device 1 (PC) is determined to have a standard usage time (operating condition) from 8:00 to 23:00.

  Corresponding to the electric device 2 (printer), “Saturday and Sunday (Saturday and Sunday)” is registered in the day item, and “Day of the week” is registered in the operation condition item. This means that “Saturday and Sunday (Saturday and Sunday)” is the operating condition information (electric device information) regarding the use of the electric device 2. In other words, the electrical equipment 2 (printer) is defined such that Saturdays and Sundays (Saturday and Sunday) are standard days of use (operating conditions).

  Corresponding to the electric device 3 (TV), “7 o'clock to 24 o'clock” is registered in the time item, and “time” is registered in the operation condition item. This means that “7 o'clock to 24 o'clock” indicates operating condition information (electric appliance information) regarding the use of the electric appliance 3. That is, it is determined that the standard usage time (operating condition) is from 7:00 to 24:00 for the electric device 3 (TV).

  Corresponding to the electric device 4 (lighting device), “18 o'clock to 6 o'clock” is registered in the time item, and “time” is registered in the operation condition item. This means that “18 o'clock to 6 o'clock” indicates operating condition information (electric device information) related to the use of the electric device 4. That is, it is determined that the standard usage time (operating condition) of the electrical device 4 (lighting device) is from 18:00 to 6 o'clock (6 o'clock the next day).

  Corresponding to the electric device 5 (heating device), “November to March” is registered in the monthly item, “16 degrees or less” is registered in the temperature item, and “monthly or temperature” is registered in the operation condition item. Is registered. This means that “November to March” or “16 degrees or less” is the operating condition information (electric device information) regarding the use of the electric device 5. In other words, it is determined that the standard use period (operating condition) of the electrical equipment 5 (heating equipment) is from November to March or 16 degrees or less (16 degrees or less regardless of the month).

  The above-described operating conditions are those that each electric device has in the initial state, and are given as standard conditions in each usage pattern. For this reason, it is considered that a case different from the actual usage method of the user may occur, but the problem is solved by gradually approaching the management table optimized for each user by updating the management table described later.

  Corresponding to each electric device, “connection position information of the electric device” is registered in the connection hierarchy item. Identification information (ID) is assigned to each of the outlet and the tap, and the management unit 142 acquires the connection information of the electric device together with the unique information of each electric device.

  For example, in FIG. 1, the outlet IDs are “00”, “01”, “02” in the order of the outlet 110 # 00, outlet 110 # 01, outlet 110 # 02, outlet 110 # 03, and outlet 110 # 04. ”,“ 03 ”, and“ 04 ”. In addition, the ID of the outlet 120 of the tap 120 is set to “a” and “b” in the order in which the outlet 120 a of the tap 120 and the outlet 120 b of the tap 120 are arranged.

  Then, the management unit 142 acquires “01” as connection information from, for example, the electric device 130 # 1 (electric device 1 (PC)) connected to the outlet 100 # 01, and corresponds to the electric device 1 (PC). Then, “01” is registered in the connection hierarchy item. Similarly, the management unit 142 acquires connection information from each of the electrical devices connected to the outlet 110 # 02, the outlet 110 # 03, the outlet 110 # 04, or the tap 120, and uses the acquired connection information as an item of the connection hierarchy. Register with. The result of registering the connection information in the connection hierarchy item in this way is the content shown in FIG.

  The value registered corresponding to the electric energy item indicates the rated electric energy (power consumption) of the corresponding electric device.

  In the first embodiment, each item of “month”, “day of the week”, “time (24-hour time notation)”, “temperature”, “operating condition”, and “electric energy” shown in FIG. The value registered corresponding to the item indicates unique information of the electric device, and the value registered corresponding to the item “connection hierarchy” indicates the connection information. These unique information and connection information are stored in the information storage unit 143 of each electrical device as electrical device information.

  Further, the values set in the above-mentioned items “monthly”, “day of the week”, “time”, and “temperature” are set as “operation period information”. Also, information (data) composed of items related to the operation period information in the electrical equipment information is referred to as an “operation period table”.

  Next, power management processing for each electrical device by the power management apparatus 140 will be described with reference to FIG.

  In the power management device 140, the management unit 142 reads the electrical device information from the information storage unit 143, confirms the operating conditions of the electrical device (step S201), and the current time counted by the time management unit 1423 is the electrical to be processed. It is determined whether or not it is included in the power-off period related to the device (step S202).

  If the management unit 142 determines in step S202 that the current time is not included in the power-off period, the management unit 142 waits until the current time is included in the power-off period, while the current time is determined in step S202. If it is determined that it is included in the power-off period, the electrical device to be processed, that is, the electrical device to be shut down, is inquired about the state of the electrical device, and the electrical device is in use based on the result of the inquiry. Whether or not (step S203).

  If the management unit 142 determines in step S203 that the processing target (shut-off target) electrical device is not in use, the management unit 142 determines that the power supply should be shut off for the shut-off target electrical device. Based on the connection information (connection layer information) registered in the connection hierarchy item corresponding to the electrical device to be shut down in the management table, the power shutdown command for the outlet or tap to which the electrical device to be shut off is connected (Power interruption command) is transmitted (step S204).

  Note that, when there are a plurality of electrical devices to be shut down under one system, the management unit 142 performs control so that the electrical device is shut off in the maximum unit that can be shut off. For example, in FIG. 1, when the electrical device 4 and the electrical device 5 are to be shut off, the power management apparatus 140 transmits a power shutdown command (power shutdown command) to the outlet 110 # 04.

  By the way, in the outlet or the tap, when the communication unit 111 receives a power shutdown command (power shutdown command) from the power management device 140 and outputs the power shutdown command to the function unit 112, the function unit 112 turns the power on. Shut off (step S211). This means that power is not supplied to the electrical device to be blocked. At the outlet or tap, the communication unit 111 transmits a power-off completion notification to the power management apparatus 140 after the power-off by the functional unit 112 is completed (step S212).

  In the power management apparatus 140, the management unit 142 transmits a power shutdown command (power shutdown command) to the outlet or tap in step S <b> 204 and then shuts off the power from the destination outlet or tap via the communication unit 141. When a completion notification is received (step S205), it is determined whether or not the power-off period related to the electrical device to be shut off has been completed (step S206).

  If the management unit 142 determines in step S206 that the power-off period has not ended, the management unit 142 determines whether or not the user (manual) has reconnected the electrical device to be disconnected (step S207). In S207, if it is determined that the reconnection of the electrical device to be blocked by the user (manual) has not occurred, the process returns to step S206.

  On the other hand, when the management unit 142 determines in step S207 that reconnection of the electrical device to be shut off by the user (manual) has occurred (reconnection of the electrical device to be shut off by the user during the power shutdown period). If power is supplied to the outlet or tap to which the relevant electrical device is connected in order to supply power again regardless of the registered contents of the management table, At the same time, it is determined that the registered contents of the management table do not match the usage pattern of the user, and requests the electrical equipment to be interrupted to update the electrical equipment information (step S207).

  If the management unit 142 determines in step S206 that the power cut-off period has expired, the management unit 142 transmits a message indicating that power should be supplied to the outlet or tap to which the electric device to be cut off is connected. (Step S209), and then returns to Step S201. Then, when the outlet or the tap starts supplying power to the power supply device to be disconnected, the power is supplied to the electrical device to be interrupted.

  If the management unit 142 determines in step S203 that the electrical device to be blocked is in use, the management unit 142 proceeds to step S208. In this case, the management unit 142 determines that the registered content of the management table does not match the usage pattern of the user, and requests the electrical device to be blocked to update the electrical device information of the electrical device.

  An example of updating the electrical equipment information will be described with reference to FIG. Information (usage state information) indicating the use state (power off or in use) of the electrical equipment is supplied by the information generation unit 132 via the communication unit 131 when the use state changes (every time the use state changes). The data is transmitted to the management device 140 and is centrally managed by the management unit 142 of the power management device 140.

  It is assumed that the operation period information at the time of new connection is an electric device, for example, electric device 130 # 1 (electric device 1), in which “8 to 23:00” is given in the time item. The information generation unit 132 of the electric device 130 # 1 (electric device 1) updates the operation period information for the time item that is a management target based on the usage record of the user.

  For example, as illustrated in FIG. 8, when the use of the electric device exceeds the set power supply connection time “8:00 to 23:00”, the information generation unit 132 at this time has passed 23:00 in this example. The operating time information is updated based on a preset time unit. In this example, the time unit to be updated is “1 hour”. When the final time of the power connection time, that is, the disclosure time of the power shut-off period is updated to “24:00” in this way, the power shut-off start time is fixed at 24:00 until it is changed again after this time. .

  Moreover, when the unused time slot | zone of an electric equipment exists in the predetermined power supply connection period in the period according to the preset number of days, that time slot | zone is defined as a power-off period. In this example, since the electrical device has not been used for a period corresponding to the number of days “D” in which the time zone (shaded portion) of “8:00 to 9:00” in the power supply connection period is preset, the information generation unit 132 It is determined that it is not suitable for the user's usage record, and “8 to 9 o'clock” is changed from the power connection period to the power cutoff period. Thus, when the final time of the power-off time, that is, the disclosure time of the power connection period is updated to “9 o'clock”, the power connection start time is fixed at 9 o'clock until it is changed again after this time. .

  FIG. 9 shows the update result of the electrical device information updated by the update process of the electrical device information shown in FIG. 8 by the information generation unit 132 of the electrical device 130 # 1 (electric device 1).

  That is, the electric device information before update shown in FIG. 9A stored in the information storage unit 133 is updated to the electric device information shown in FIG. 9B. In the example illustrated in FIG. 9, the “time” item that is a management item is inherited as it is, and only the time is changed from “8 to 23:00” to “9 to 24:00”.

  Basically, the management item is not changed, but if the management item that has not been defined since the first connection also has a noticeable tendency from the usage history, the information generation unit 132 manages the management item. Add to target management items for further optimization.

  Next, electrical appliance connection determination processing by the power management apparatus 140 will be described with reference to FIG.

  When a new electric device is connected (newly connected) to the outlet 110 or the tap 120, or when the removed electric device is connected to the outlet 110 or the tap 120 again, in the power management device 140, the management unit 142 Then, the electric device information of the connected electric device 130 is acquired (step S301).

  The management unit 142 collates the electrical device information acquired in step S301 with the management table of the connected electrical device stored in the information storage unit 143, and separates the outlets of the same system based on the collation result. It is determined whether or not a plurality of electrical devices are connected, that is, whether or not there are a plurality of electrical devices in the same outlet (step S302).

  If the management unit 142 determines in step S302 that there are a plurality of electrical devices in the same outlet, whether or not the operation periods (power connection periods) corresponding to the plurality of connected electrical devices compete with each other. Is determined (step S303).

  If the management unit 142 determines in step S303 that the operation periods (power supply connection periods) corresponding to the plurality of electrical devices are competing, the total amount of power when the plurality of electrical devices 130 are simultaneously operated is determined. It is determined whether or not the allowable amount of the outlet is exceeded (step S304).

  When the management unit 142 determines in step S304 that the total power amount of the plurality of electrical devices exceeds the allowable amount of the outlet, the management unit 142 rejects the connection of the connected electrical devices (step S305). The result (notifying the connection of the electric device is rejected) is presented to the user (step S306), and then this process is terminated.

  In step S306, when the plurality of electric devices are connected to the same outlet, the management unit 142 exceeds the allowable amount of the outlets, so that the connected electric device should be connected to another outlet. It will be presented to the user.

  As a presentation method to the user, lighting by a warning LED (light emitting diode) (not shown) on the power management device 140, and the connected electric device 130 # 1 (electric device 1 (PC)) or electric device 130 # 3 (electrical device) Presentation by display output on the device 3 (TV)) or presentation by print output on the electric device 130 # 2 (electric device 2 (printer)).

  When the management unit 142 determines in step S302 that a plurality of electrical devices are not present in the same outlet, the management unit 142 determines in step S303 that the operation periods (power connection periods) corresponding to the plurality of electrical devices are not in conflict. If it is determined in step S304 that the total power amount of the plurality of electric devices does not exceed the allowable amount of the outlet, new connection of the electric device is permitted (step S307), and then this process ends.

  In the multifunction device 200 # 1, the control determination unit 210 performs initialization when the switch 230 is turned on (when the power of the multifunction device is turned on) (step S601).

  After the initialization is completed, the control determination unit 210 searches for peripheral devices connected to the same power line 204 by power line communication via the power line communication unit 220 (step S602), and based on the result of this search, It is determined whether there is another multifunction device (step S603).

  In step 603, the control determination unit 210 shifts to a normal operation when there is no other multifunction peripheral in the vicinity (step S604). On the other hand, if another multifunction peripheral exists in the vicinity, the control determination section 210 # 1. And the efficiency of the peripheral device are compared (step S605). Details of the processing for comparing the efficiency are described later (see FIGS. 20 and 21).

  In step 605, the control determination unit 210 shifts to normal operation when the peripheral multifunction peripheral determines that the performance of the peripheral multifunction peripheral is better than the multifunction peripheral (step S606). If it is determined that the performance is worse than that of the MFP, the performance comparison result data is notified to the user (step S607).

  Details of this comparison result data notification to the user will be described later (see FIG. 22). Also, a user interface for notification of comparison result data will be described later (see FIG. 27).

  The control determination unit 210 determines whether input information (selection information) corresponding to the determination (selection) from the user who has notified the performance comparison result is input based on the information provided from the input device 270. (Step S608). Details of the determination process for determining whether or not this input information (selection information) has been input will be described later (see FIG. 23).

  If it is determined in step S608 that the input information (selection information) is not input, the control determination unit 210 waits until the input information (selection information) is input, while the input information (selection information). If it is determined that the input is input, an operation corresponding to input information (selection information) from the input device 270, that is, information selected by the user is executed (step S609). Details of the execution of the operation according to the information selected by the user will be described later (see FIGS. 24 to 26).

  Thereafter, the control determination unit 210 shifts to a normal operation of the multifunction machine (step S610).

  Next, the performance judgment process based on the comparison of the efficiency between the multifunction peripheral as the second electrical device and the peripheral device (in-house product) as the first electrical device will be described with reference to FIG.

Step S704).

  If the control determination unit 210 determines in step S704 that the model number does not exist in the device list, the control determination unit 210 requests product information from the external server 205 installed in the manufacturer, and acquires product information from the external server 205 (step S704). S705).

  When it is determined in step S704 that the model number exists in the device list, the control determination unit 210 compares the superiority and inferiority in the comparison table stored in the storage device 240 because the products are in-house products (step S706). The result is output (displayed) on the display device 260, for example (step S707).

  The comparison table is stored in the storage device 240, but may be downloaded from a server (not shown) that stores the comparison table.

  Next, the performance judgment process based on the comparison of the efficiency between the multifunction peripheral as the second electrical device and the peripheral device (other company's product) as the first electrical device will be described with reference to FIG.

  In the multifunction device as the second electric device, for example, the multifunction device 200 # 1, the control determination unit 210 takes in the model number and built-in parameter (Parameter) of the peripheral device from the storage device 240 (step S801).

  The control determination unit 210 inquires of the external server 205 installed in the peripheral device or manufacturer about the function and the capability value (spec predetermined by the industry standard) (step S802).

  The control determination unit 210 determines whether or not the peripheral device is within the product life based on the information acquired in step S801 (step S803). If the result of this determination is that the peripheral device exceeds the product life, Since the peripheral device has expired, the process proceeds to the peripheral device processing so that the user can stop using the peripheral device (step S804). The details of the processing of this peripheral device will be described later (to FIGS. 24 to 26, however, the product cannot be sold because the product has expired).

  If the control determination unit 210 determines in step S803 that the peripheral device is within the product lifetime, the control determination unit 210 performs the following four comparison processes.

  That is, the control determination unit 210 compares the MFP 200 # 1 with all the functions of the peripheral device (step S805), and the MFP 200 # 1 is superior to the peripheral device in terms of toner cost. Comparison processing (step S806), comparison processing (step S807) of whether the multifunction device 200 # 1 is superior to the peripheral device in standby power, and the multifunction device 200 # 1 is superior in function specification to the peripheral device If the result of all the comparison processes is “YES”, it is recognized that the multifunction device 200 # 1 is superior to all the peripheral devices (step S809). .

  If even one of the four comparison processes (steps S805 to S808) results in “NO”, the control determination unit 210 does not mean that the multifunction device 200 # 1 is superior to the peripheral device in all functions. Recognize (step S810).

  Comparison processing in step S805

  Question 1: Does it cover all functions of peripheral devices?

  For this, determine whether the basic functions such as FAX, scanner, copy, and print are included.

  Comparison processing in step S806

  Question 2: Is toner cost superior to peripheral devices?

  This is determined by the toner cost (color, monochrome, etc.) per sheet at the time of printing. For example, color = X circle, monochrome = Y circle, and the like.

  Comparison processing in step S807

  Question 3: Is standby power superior to peripheral devices?

  This is determined based on which of the standby powers of the multifunction machine is less. For example, minimum power = XW (X watts) or less. Power consumption (such as TEC value) in an operation pattern determined in the industry = Y or less.

  Comparison processing in step S808

  Question 4: Is it superior to peripheral devices in function spec?

  In this regard, it is judged whether the function (function standard) of the multifunction device is superior. For example, for a printer, color printing speed = X (sheets / minute), monochrome printing speed = Y (sheets / minute), resolution = ZZZ (dpi), and the like.

  Next, a notification destination selection process to the user by the MFP 200 # 1 as the second electric device will be described with reference to FIG.

  In multifunction device 200 # 1, control determination unit 210 determines whether the functions of the LCD, buttons, and buzzer of its own device (multifunction device 200 # 1) are sufficient for notification to the user (step S901). .

  If the control determination unit 210 determines in step S901 that the above functions are sufficient for notification to the user, the control determination unit 210 proceeds to notification work using the LCD of the device itself (step S902). If it is determined that the above functions are insufficient for notification to the user, the connection state of the host computer 201 is confirmed based on information from the various interfaces 250 (step S903).

  When determining that the host computer 201 is in the connected state in step S903, the control determination unit 210 notifies the user using the host computer 201 (step S904).

  If the control determination unit 210 determines in step S903 that the host computer 201 is not connected, the control determination unit 210 inquires of other peripheral devices as to whether the host computer 201 has a display function (step S905).

  If the control determination unit 210 determines in step S905 that there is a peripheral device (such as a television) having sufficient performance for user notification, the control determination unit 210 uses the peripheral device to notify the user (step S906). If it is determined that there is no peripheral device with sufficient performance, it cannot be displayed this time, and is displayed at the next startup (step S907).

  Next, a notification process to the user from the MFP 200 # 1 as the second electric device and a selection process by the user will be described with reference to FIG.

  List the peripheral status to the user. If even one device to be canceled is selected from the list, all devices are not used together, and the process proceeds to the direction not using them. On the other hand, if no item is selected, the process proceeds to the combined use.

  The user determines whether or not all the devices are used together (step S1001). As a result of the determination, if the devices are used together, it is determined whether or not the devices displayed in the current list will be displayed again after the next time. (Step S1002).

  If it is selected in step S1002 that it will not be displayed in the future, the control determination unit 210 stores the model number, serial number, and the like in the storage device 240 and sets them so that they will not be displayed in the future (step S1003). Thereafter, the control determination unit 210 shifts to a normal multifunction peripheral operation (step S1004).

    If not used in step S1001, the user determines whether to dispose of the device (step S1005).

  In step S1005, when the user determines not to dispose of this time, the control determination unit 210 displays that the power cable is disconnected from the outlet in order to stop the power supply of the corresponding device to cut standby power (step S1006). The process proceeds to step S1004.

  If the user decides to dispose of the corresponding device in step S1005, the control determination unit 210 asks the user whether to take over the setting information of the corresponding device to the newly introduced multifunction device 200 # 1 (step S1007).

  If it is determined in step S1007 that the setting is to be taken over, the control determination unit 210 transfers data related to the setting between the corresponding device and the multifunction device 200 # 1 (step S1008).

  The control determination unit 210 asks the user whether or not to display the disposal or sale method of the corresponding device (step S1009).

  When displaying in step S1009, the control determination unit 210 proceeds to the peripheral device processing (main flow) shown in FIG. 24 (step S1010).

  In step S1009, when the user determines not to display this time, the control determination unit 210 proceeds to step S1006.

  Note that if it is determined that a plurality of devices are not necessary, the control determination unit 210 determines in order whether or not to dispose of each before entering the normal operation of the multifunction device.

  Next, treatment processing of the peripheral device by the MFP 200 # 1 as the second electric device will be described with reference to FIG.

  In the MFP 200 # 1, the control determination unit 210 transmits information about the target peripheral device and user information to the external server 205 (step S1101). The external server 205 indicates a server installed in (manufacturer, second-hand trader, local government (disposal method, etc.)).

  The control determination unit 210 takes in information related to the processing method selected from the external server 205 via the power line communication unit 220 (step S1102).

  The control determination unit 210 displays the processing method to the user and requests selection as shown in a user interface as shown in FIG. 28 (step S1103).

  Based on the input information (selection information) from the input device 270, the control determination unit 210 determines whether or not to perform a disposal procedure this time (step S1104). Then, the procedure proceeds to the detailed procedure of the processing method (see FIG. 25) (step S1105). On the other hand, if the disposal procedure is not performed, the procedure proceeds to the procedure for prohibiting the use of peripheral devices (see FIG. 26) (step S1106).

  Next, processing of the peripheral device by the multifunction peripheral 200 # 1 as the second electric device will be described with reference to FIG.

  In the MFP 200 # 1, the control determination unit 210 redisplays the request destination of the selected disposal method, the disposal cost (or gain on sale), and the like (step S1201), and determines whether or not the disposal of the peripheral device is really executed. Confirmation is requested (step S1202).

  If the control determination unit 210 determines in step S1202 to cancel the disposal, the procedure ends, and the process proceeds to the normal operation of the multifunction machine (step S1203).

  When it is determined that the disposal is to be executed in step S1202, the control determination unit 210 inquires of the user whether or not to apply online regarding the disposal (step S1204).

  When the online application is selected in step S1204, the control determination unit 210 transmits the application content to the request destination (step S1205), receives the response, and causes the display device 260 to display the application result (step S1206). .

  In step S1206, the control determination unit 210 may print out the application result from the printing apparatus 280.

  After completing step S1206, the control determination unit 210 proceeds to a peripheral device use prohibition procedure (see FIG. 26) (step S1207).

  If the online determination is not made in step S1204, the control determination unit 210 prints out the application form or outputs the file to the user (step S1208), and then proceeds to step S1207.

  Next, the peripheral device use prohibition procedure control processing by the multifunction peripheral 200 # 1 as the second electric device will be described with reference to FIG.

  All the settings for the peripheral devices are made via the multifunction device 200 # 1. The interface with the user is performed using the interface selected in the notification destination selection process shown in FIG.

  In multifunction device 200 # 1, control determination unit 210 causes the user to select whether or not to erase the internal data of the peripheral device, and erases the internal data of the peripheral device based on the input information (selection information) from input device 270. It is determined whether or not to perform (step S1301).

  If it is determined in step S1301 that the internal data is to be deleted, the control determination unit 210 performs control to cause the peripheral device to delete the internal storage area (hard disk, storage ROM, etc.) via the power line communication unit 220 ( Step S1302).

  Next, the control determination unit 210 determines whether to prohibit the activation of the peripheral device in the future based on the input information (selection information) from the input device 270 according to the operation indicating whether or not the user will prohibit the activation of the peripheral device in the future. It is determined whether or not (step S1303).

  If the control determination unit 210 determines in step S1303 that the activation of the peripheral device is prohibited, the control determination unit 210 executes the peripheral device activation prohibition process, that is, turns on the power to the peripheral device via the power line communication unit 220. In such a case, it is instructed not to start again (step S1304).

  Next, the control determination unit 210 notifies the notification destination selected in the notification destination selection process shown in FIG. 22 and displays that the peripheral device power cable should be disconnected from the outlet in order to reduce standby power. (Step S1305).

  Thereafter, the control determination unit 210 shifts to the normal operation of the multifunction machine 1 (step S1306).

  If the control determination unit 210 determines in step S1301 not to delete the internal data of the peripheral device, the control determination unit 210 proceeds to step S1303.

  If the control determination unit 210 determines in step S1303 that the activation of the peripheral device is not prohibited, the process proceeds to step S1305.

  Next, an example of a user interface for displaying a list of the statuses of peripheral devices will be described with reference to FIG.

  In the example shown in FIG. 27, the devices are displayed from the top in ascending order of efficiency. The user performs an operation of inputting the determination in the use stop setting portion and pressing the OK button.

The meaning of each item displayed in the user interface is as follows. Note that the items are merely examples, and may be added or reduced.
Use stop setting: Indicates the part to input user settings. Set the check point (check) when not in use.
Discontinuation recommendation: Indicates an apparatus that the multi-function peripheral 1 has determined that it is better not to continue using it due to the efficiency of power, toner cost, and the like. The symbol “◯” is assigned corresponding to the corresponding device (model name).

Scan spec (spec) value: Color and monochrome scan speed (sheets / minute).

  Although not shown in FIG. 27, important specification values for comparing use continuation are displayed on the user interface.

  As a way of recommending cancellation, there is also an idea that the same function for backup is at least two devices. That is, if there are three models with the same function, one model with the lowest efficiency is recommended, and if there are four models, the two models with the lowest efficiency are recommended.

  Next, an example of a user interface at the time of selecting a disposal method for the peripheral device will be described with reference to FIG.

  The user interface is displayed in the order in which the cost burden for the user (if it is negative, the profit on sale) is reduced. The user performs an operation of inputting a check mark for the selected method and pressing the OK button.

The meaning of each item displayed in the user interface is as follows. Note that the items are merely examples, and may be added or reduced.

  In the fourth embodiment, information is transmitted and received by power line carrier communication using a power line. However, the present invention is not limited to this, and information is transmitted by communication using a communication network such as a network or a communication line. May be transmitted / received.

  As described above, in the fourth embodiment, when a multifunction machine is newly installed, an old device is detected and a subsequent processing method is presented to the user. Then, by allowing the user to select a processing method, the existing setting of the old device is diverted, and the amount of setting work for the user's own new multifunction device is reduced.

  Newly introduced multifunction devices detect old inefficient models and prompt users to discontinue or dispose of them, thereby reducing costs for consumables and power (operation, standby) usage, etc., and contributing to energy conservation To do.

  It is also applied to a mechanism that detects devices that are no longer needed due to technological advances and encourages disposal. For example, a video recorder when a hard disk recorder was developed.

  By providing recommended information to the user so as to ensure a plurality of the same functions when prompting disposal, a backup function in the event of a failure is also ensured.

  The newly introduced multifunction peripheral itself checks the disposal or sale method and notifies the user, thereby reducing the burden of the user's disposal or sale. It also helps reduce illegal dumping by directing users to proper disposal and sale.

  The newly installed MFP confirms the device life of the existing equipment, and accepts the device life of devices that do not have a user interface. As a result, it is possible to prevent breakdown of home appliances due to continued use even after the life of the device.

  The notification unit 305 notifies the administrator at the time of theft.

  The timer 306 outputs date / time information.

  The power switch 307 is switched between an on state and an off state. When the power switch 307 is on, the power switch 307 supplies power provided from the power line L2 to the function unit 301. When the power switch 307 is off, the function unit 301 is turned on. The supply of power provided from the power line L2 is cut off.

  Note that the storage unit 302, the power line communication unit 303, the information control unit 304, the notification unit 305, and the timer 306 are supplied with power from the power line L2 regardless of whether the power switch 307 is on or off.

  Note that power from the power line L2 is supplied to the storage unit 402, the power line communication unit 403, the information generation unit 404, and the timer 405 regardless of whether the power switch 406 is on or off.

  In the fifth embodiment, the electric device (in this example, a printer) has a timer, but the date and time information is acquired from the device management apparatus (in this example, a multifunction device) each time the operation mode is changed. By doing so, you may make it the structure which does not have a timer in an electric equipment.

  The printers 400 # 2 to 400 # 6 have the same functional configuration as the printer 400 # 1.

  Device information transmission processing of the printer 400 # 1 will be described with reference to FIG.

  Here, the case of the printer 400 # 1 will be described, but it is assumed that the printers 400 # 2 to 400 # 6 perform the same processing as the printer 400 # 1.

  When printer 400 # 1 is connected to an outlet, and power line communication unit 403 and information generation unit 404 detect connection to power line L2 (step S1510), information generation unit 404 stores the model number stored in advance from storage unit 402, The device information such as the serial number is acquired (step S1511), and the device information is transmitted to the multi-function device 300 through the power line communication unit 403 and the power line L2 (step S1512).

  The information generation unit 404 determines whether or not a device information acquisition notification has been received from the multifunction device 300 through the power line communication unit 403 and the power line L2 (step S1513). As a result of the determination, the information generation unit 404 receives the device information acquisition notification. If not, on the other hand, if the device information acquisition notification is not received, the information generation unit 404 determines whether or not the device information has been transmitted a predetermined number of times (step S1514). .

  If the information generation unit 404 determines in step S1514 that the specified number of times has been performed, the information generation unit 404 determines that the multifunction device 300 that performs device management is not installed, ends the process, and determines that the specified number of times has not been performed. In this case, the process proceeds to step S1512 and device information is transmitted.

  Next, device information registration processing of the multifunction device 300 will be described with reference to FIG.

  In the MFP 300, when the information control unit 304 receives the device information of the printer 400 # 1 from the printer 400 # 1 from the power line communication unit 403 and the power line L2 from the 400 # 1 (step S1520), the printer 400 # A device information acquisition notification is transmitted to 1 through the power line communication unit 403 and the power line L2 (step S1521).

  Next, the information control unit 304 acquires a device information registration list from the storage unit 302 (step S1522), and determines whether the device information of the printer 400 # 1 is registered in the device information registration list (step S1523). .

  If the information control unit 304 determines in step S1523 that the device information is not registered, the device information of the printer 400 # 1 is added to the device information registration list, and the storage unit 302 is added. The list is stored (step S1524).

  The information control unit 304 outputs the device information of the printer 400 # 1 to the function unit 101, and the function unit 101 notifies the administrator of the device information of the printer 400 # 1 (step S1525), and then ends the process.

  If the information control unit 304 determines in step S1523 that the device information has been registered, the information control unit 304 proceeds to step S1525.

  Here, the device information registration process will be described with a specific example.

  For example, if the notification destination is the personal computer P1 (or personal computers P2 to P8) used by the administrator, the functional unit 301 uses the network I / F function to use the personal computer P1 used by the administrator through the network L1. (Or notify the personal computers P2 to P8 of the device information). When the personal computer P1 (or personal computers P2 to P8) used by the administrator receives the device information from the multifunction device 300, the device information as shown in FIG. 34 is displayed to the administrator.

  The administrator sets or confirms the nickname and theft prevention process in the displayed device information as shown in FIG. The personal computer P1 (or personal computers P2 to P8) transmits the device settings for the printer 400 # 1 set or confirmed by the administrator to the multi-function device 300 through the network L1.

  Further, the initial value of the anti-theft process setting may be validated so that the anti-theft process is automatically activated when the device setting is not performed due to absence of an administrator or the like.

  Next, device setting registration processing of the multifunction device 300 will be described with reference to FIG.

  When the information control unit 304 receives the device setting of the printer 400 # 1 from the personal computer P1 through the function unit 101 and the network L1 (step S1530), the information control unit 304 acquires the device information registration list from the storage unit 302 (step S1531). Then, the device settings of the printer 400 # 1 in the device information registration list are updated, the storage unit 302 stores the device information registration list as shown in FIG. 36 (step S1532), and the process is terminated.

  Also, when the administrator changes the device settings of each device or deletes device information from the device information registration list due to device disposal or the like, the administrator requests the device information registration list from the personal computer P1 to the MFP 300. 37, settings are made in accordance with the display of the device information registration list as shown in FIG. 37, and the multifunction device 300 updates the device information registration list in the same manner as the device setting registration process shown in FIG.

  In the example shown in FIG. 37, the anti-theft processing of the printer 400 # 7 and the printer 400 # 8 that are no longer used and removed from the outlet is invalidated, and the printer 400 # 8 is deleted from the device information registration list due to disposal or the like. belongs to.

  The multifunction device 300 performs anti-theft processing and collects power consumption information according to the device information registration list created in this way.

  Further, when the anti-theft setting is disabled and deletion from the list is enabled, a flow for performing administrator authentication in consideration of security may be added.

  Next, the anti-theft process of the multifunction machine 300 will be described with reference to FIG.

  In the MFP 300, the information control unit 304 compares the anti-theft processing start time set in advance with the date / time information from the timer 306, and determines whether it is the anti-theft processing start time (step S1540). .

  If the information control unit 304 determines in step S1540 that the anti-theft process start time is not reached, the information control unit 304 stands by until the anti-theft process start time is reached. The device information registration list is acquired from the unit 302 (step S1541), and the installation confirmation including the device information of the printer 400 # 1 is transmitted to the printer 400 # 1 through the power line communication unit 303 and the power line L2 according to the device information registration list acquired in step S1541. A request is transmitted (step S1542).

  The information control unit 304 determines whether an installation confirmation response is received from the printer 400 # 1 through the power line communication unit 303 and the power line L2 (step S1543).

  When the information control unit 304 cannot receive the installation confirmation response from the printer 400 # 1 in step S1543, the information control unit 304 notifies the administrator of the notification example as shown in FIG. 40 through the notification unit 306 and the telephone line L3 (step S1543). After that, the processing is terminated.

  If the information control unit 304 has received an installation confirmation response from the printer 400 # 1 in step S1543, the information control unit 304 confirms the device information registration list and determines whether or not the installation confirmation of all the printers that perform the installation confirmation has been performed. Judgment is made (step S1545).

  If the information control unit 304 determines in step S1545 that installation confirmation of all printers that perform installation confirmation has not been performed, the information control unit 304 proceeds to step S1542, and on the other hand, performs installation confirmation of all printers that perform installation confirmation. If it is determined that the anti-theft processing end time is set in advance and the date and time information from the timer 306 is compared, it is determined whether or not the anti-theft processing end time is reached (step S1546).

  If the information control unit 304 determines in step S1546 that the anti-theft process end time is reached, the information control unit 304 ends the process. On the other hand, if the information control unit 304 determines that the anti-theft process end time is not reached, the information control unit 304 confirms the previous installation. The time, the preset installation confirmation cycle, and the date / time information from the timer 306 are compared to determine whether or not a preset time has elapsed (step S1547).
