  First, in FIG. 1 showing the overall configuration of the power control system S1, a power control server (power control information providing means) in which communicable electrical devices 102, 103, and 104 manage the power load of the power line L via the indoor power line L. ) 101.

  The power control server 101 includes a power breaker (breaker) 106 and is connected to an outdoor wiring H serving as a power supply source.

  As the electric devices 102, 103, and 104 capable of communication, for example, so-called digital home appliances such as a refrigerator, an air conditioner, a lighting device, a printer, and a personal computer provided with communication means corresponding to power line communication described later are assumed.

  The power control server (power control information providing means) 101 is configured by a computer (for example, a host computer, a microcomputer, a program for realizing a server function, etc.) connected by power line communication via the power line L, and the like. Data relating to power control such as power amount information is provided to the devices 102, 103, and 104.

  Here, power line communication will be described.

  Power line communication is a technology that uses a 100 V (50/60 Hz) power line as a communication line, and an adapter for communication (PLC modem (power line communication modem) or PLC (Power Line Communications modem) card (power line communication card). )) Is connected to an electrical device such as a personal computer or a printer to superimpose a high-frequency signal (4 MHz to 28 MHz) on the power line and enable data communication of several Mbps to several hundred Mbps using the power line as a transmission line. It is.

  The power line communication modem has a function of extracting only digital data from the power line, sending the data to various electric devices, and sending information from the various electric devices to the power line.

  Since electrical wiring is stretched around houses and offices, it has the advantage of being able to easily build a local communication network without laying new cables. In addition, the distribution network of the electric power company can be used as it is as a communication infrastructure, and an Internet connection service is also possible.

  The electric devices 102, 103, and 104 communicate with the power control server 101 via the power line L when a change in power to be used occurs due to a change in operation or the like, and how much power is currently available. Is performed as an “inquiry about the amount of power that can be used”.

  Each electric device 102, 103, 104 determines whether or not to operate and an operation mode (operation mode) based on the amount of power that can be supplied from the power control server 101.

  Next, each electrical device 102, 103, 104 notifies the power control server 101 of the scheduled power usage amount in the determined operation mode, and then starts operation.

  In addition, the power control server 101 sets an upper limit value A that can be supplied to the power line L in advance, and can be currently supplied according to the power usage scheduled amount information from each of the electric devices 102, 103, and 104 connected to the power line L. A table (table information) 105 for calculating the electric energy B is stored in a storage device (information storage means: not shown).

  In response to an inquiry about the amount of usable electric power from each of the electric devices 102, 103, and 104, the calculated supplyable amount B is returned.

  Next, the configuration of the electric device according to the first embodiment will be described with reference to the block diagram of FIG.

  Here, the electric device 102 will be described as an example, but the electric devices 103 and 104 have the same configuration.

  The electrical device 102 has a function of communicating through the power line L, and includes a communication data combining unit 202 that performs electrical connection with the power line L, a power supply unit 203 that supplies power to each unit, and a communication control unit that performs communication control 204, a power breaker (breaker) 205 that cuts off the power supply, and a main operation unit (realization means) 206 that realizes the original function of the electric device. The communication data combining unit 202, the power supply unit 203, the communication control unit 204, and the power breaker 205 constitute an electric device terminal C.

  The communication data combining unit 202 has a function of separating communication data superimposed on the power line L or superimposing communication data on the power line L.

  The power supply unit 203 includes an AC / DC conversion so that the supplied power can be used inside the electric device 102 and a power supply unit that converts various voltages used inside.

  When the communication control unit 204 detects an operation instruction from the user, the communication control unit 204 makes an “inquiry of available power” to the power control server 101 through the power line L, and the main operation unit 206 based on the available power. The operation mode (operation mode) and the amount of electric power supplied to the inside are determined, and are constituted by a microcomputer or the like.

  In addition, the communication control unit 204 performs data transfer with the main operation unit 206 via the communication interface (I / F) unit 208 between the communication lines 207, issue of a control command to the operation mode, and the like.

  The power breaker 205 cuts off the power from the power supply unit 203 by a control signal from the communication control unit 204. In addition, the power line L interrupted | blocked by the power circuit breaker 205 is not necessarily one system.

  The main operation unit 206 is a part that realizes a main function of the electric device.

  The main operation unit 206 is a part where the power supply may be cut off during standby, but is a part that requires a large amount of power during operation.

  For example, when the electric device 102 is an air conditioner, the main operation unit 206 corresponds to a drive system motor, a heater as a heating unit, or the like. When the electric device 102 is a laser printer or the like, the main operation unit 206 corresponds to a printer engine including a drive system motor and an image processing apparatus.

  In order to realize the same function, the main operation unit 206 includes a high-speed mode that consumes a large amount of instantaneous power and a low-power mode that suppresses instantaneous power consumption by reducing the motor rotation speed or lowering the heater temperature. You can

  Next, with reference to the flowchart of FIG. 3, the process sequence of the power control process performed by the power control system S1 having the above configuration will be described.

  When the power control process is started, when the power switch of the electric device terminal C is turned on in step S301, the process proceeds to step S302, power is supplied only to the communication control unit 204, and the process proceeds to step S303.

  In step S303, the communication control unit 204 inquires of the power control server 101 about the currently available power via the power line L, and then proceeds to step S304.

  In step S304, it is determined whether or not the electric power necessary for initializing the electric device 102 (103, 104) is sufficient. If not enough, the apparatus waits until it can be supplied, and if it is determined that it is sufficient. The process proceeds to step S305.

  In step S305, it is determined whether or not initialization is possible in a high-speed mode that uses a lot of power for initialization of the electric device 102 (103, 104) with available power.

  Then, after notifying the power control server 101 of power required for initialization in the high speed mode (step S306), the communication control unit 204 operates the power breaker 205 to supply power to the main operation unit 206 (step S307). ), The main operation unit 206 performs initialization in the high-speed mode (step S308).

  On the other hand, if “No” is determined in step S305 (when initialization is performed in the low power mode because sufficient power cannot be supplied in the high speed mode), the initialization is performed in the low power mode. After notifying the power control server 101 of the necessary power (step S309), the communication control unit 204 operates the power breaker 205 to supply power to the main operation unit 206 (step S310). Initialization is executed in the mode (step S311).

  In the low power mode, power consumed instantaneously can be suppressed by processing such as operating a motor, a heater, etc. in time series, but the processing time is slower than in the high speed mode.

  Next, when initialization is completed (step S312), the entire apparatus is energized, but shifts to standby mode 1 where no operation is performed (step S313).

  In step S314, the power control server 101 is notified of the scheduled power usage in the standby mode 1, and when an operation instruction is generated from the user (step S315), the power control server is connected with the power currently available to the power control server. And waits until the power necessary for the instructed operation can be supplied (steps S321 and S322).

  Next, when the power necessary for the instructed operation is ready to be supplied, it is determined whether to execute in the high-speed mode that uses a large amount of power or in the low-power mode that suppresses power (step S323).

  If it is determined in step S323 that the operation in the high speed mode is possible, the power control server 101 is notified of the power required for the high speed mode operation (step S324), and then the process is executed in the high speed mode (step S326). .

  If sufficient power for high-speed mode operation cannot be supplied in step S323 and operation is performed in low-power mode, the power control server 101 is notified of power required for low-power mode operation (step S327), and then low. Processing is executed in the power mode (step S329).

  Also in this case, in the low power mode, power consumed instantaneously can be suppressed by processing such as operating a motor, a heater, etc. in time series, but the processing time is slower than in the high speed mode. When the process ends (step S330), it is determined whether there is an instruction from the next user (step S331). If there is no instruction, the process proceeds to the standby mode 1 (step S313). The power control server 101 is inquired about the power required for the operation (step S321).

  In addition, after the transition to the standby mode 1, if no operation instruction is issued from the user for a certain time, the transition to the power saving mode 2 in which the power supply of the main operation unit 206 is cut off is performed (step S317).

  When the power saving mode 2 is entered, the communication control unit 204 controls the power breaker 205 to cut off the power supply to the main operation unit 206, and then notifies the power control server 101 of the scheduled power usage in the standby mode 2. Here, the standby mode 2 is a mode in which the power supply other than the communication control unit 204 is stopped and the power control server 101 is notified of the power to be used.

  Note that the embodiment assumes an electrical device that requires a large amount of power when performing initialization, such as a laser printer. For an electrical device that does not require initialization, the process proceeds directly from step S301 to step S321. May be.

  Next, an example of a power change when the power control system S1 according to the first embodiment is operated will be described with reference to the graph of FIG.

  First, when the power is turned on, the electric device 102 (103, 104) supplies power to the communication control unit 202, determines whether it is possible to supply the power control server 101 with power necessary for initialization of the device, When it is determined that the power required for initialization can be supplied, the power control server 101 is notified of the power required for initialization (state 401).

  When the notification of the power necessary for initialization is completed with respect to the power control server 101, power is supplied to the entire apparatus to perform initialization.

  This example shows a case where initialization in the high-speed mode is possible (state 402).

  After the transition to the standby mode 1 where the apparatus operation is stopped when the initialization is completed, the power control server 101 is notified of the scheduled power usage in the standby mode 1 and waits for an operation instruction from the user.

  Next, when an operation instruction from the user is generated, it is checked whether or not power capable of operating the apparatus can be supplied to the power control server 101. (State 403).

  After the notification, the electric device 102 (103, 104) supplies power to the entire apparatus and executes the operation (state 404).

  Then, after shifting to the standby mode 1 where the apparatus operation is stopped when the process is completed, the power control server 101 is notified of the scheduled power usage in the standby mode 1 and waits for an operation instruction from the user.

  Next, when an operation instruction from the user is generated, it is checked whether or not power capable of operating the apparatus can be supplied to the power control server 101. (State 405).

  After the notification, the electric device supplies power to the entire apparatus and executes the operation (state 406). In this case, since it is a low-speed mode, the power used instantaneously is suppressed, but the processing time is long.

  After shifting to the standby mode 1 where the apparatus operation is stopped when the processing is completed, the power control server 101 is notified of the power to be used in the standby mode 1 and waits for an operation instruction from the user (state 407). ).

  If no operation instruction is issued from the user for a certain period of time, the power to the main operation unit 206 is cut off, the process shifts to the standby mode 2, and the power control server 101 receives power required for the standby mode 2. And waits for an operation instruction from the user (state 408).

  When an operation instruction from the user is generated, it is confirmed whether or not the power capable of operating the apparatus can be supplied to the power control server 101. If the power can be supplied, the power control server 101 is notified of the scheduled power usage during operation. Then, power is supplied to the main operation unit 206 to start the operation (state 409).

  According to the power control system S <b> 1 according to the first embodiment, by communicating with the power control server 101 through the power line L, the electric device 102 (103, 104) determines the operation mode from the currently available power amount. It is not necessary to implement a management program for each electric device on the power control server 101 side, and what state of the electric device is about the electric device whose power consumption changes in time series and the electric device having a plurality of operation modes Can be grasped, and the dynamically changing power consumption can be managed stably. In addition, since the power control server 101 only needs to obtain power that can be newly supplied based on the total amount of power currently scheduled to be used by each of the electric devices 102, 103, and 104, the processing on the power control server 101 side is reduced. be able to. In addition, since it is not necessary to control the power control server 101 so as not to exceed the rated power amount, efficient control can be performed even when many devices that do not support power control are connected. In addition, when the electrical devices 102 to 104 are operating, it may not be possible to perform a normal stop or switching control to an operation mode with low power consumption, but it is necessary to reduce power as in the past. At this point in time, there is no one-way power cut or low power control instruction to the electric devices 102 to 104 regardless of the state of the devices. Absent. In addition, there is an advantage that it is not time-consuming because it is not necessary to set scheduled power usage in all operation modes on the power control server 101 side and to introduce an operation control power management program on the power control server 101 side.

  Next, the power control system S2 according to the second embodiment will be described with reference to FIG. 5 and FIG.

  In addition, about the same structure as electric power control system S1 which concerns on 1st Embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The difference from the power control system S1 according to the first embodiment is a case in which the electric device is activated by a timer or the like, in advance the activation reservation on the power control server 101 side, the scheduled power at the time of activation, When it starts, it is a place to notify the scheduled use period.

  Electrical devices 102, 103, 104 capable of power line communication are connected to the power line L, and the power control server 101 manages the power load of the monitored power line L so that they operate stably. The electric devices 102, 103, and 104 have substantially the same configuration as that connected to the power control system S1 according to the first embodiment (see FIG. 2), but are activated at a set time in this embodiment. It is necessary to provide a possible timer (set time starting means).

  When a change in power to be used occurs due to a change in operation or the like, the electrical devices 102, 103, and 104 communicate with the power control server 101 via the power line L and notify the power that the user wants to use. Whether or not the power can be used is performed as an “inquiry about the amount of usable power”. Then, based on the suppliable power returned from the power control server 101, the availability of the operation and the operation mode (operation mode) are determined, and the power use scheduled amount and the scheduled use period in the determined operation mode are stored in the power control server 101. After notification, the operation starts.

  When the electric devices 102, 103, and 104 are started by a timer, the power control server 101 is notified of the scheduled start time and the scheduled power at the time of start, and the power control server 101 is again re-established how much power is present at the start of the timer. An inquiry is made as to whether or not the power can be used, and whether or not the operation is possible is determined based on the power supply available amount returned from the power control server 101.

  In addition, the power control server 101 sets an upper limit value D that can be supplied to the power line L in advance, and can be currently supplied according to the power usage scheduled amount information from each of the electric devices 102, 103, and 104 connected to the power line L. A table (table information) 505 for calculating the electric energy is stored in a storage device (information storage means: not shown).

  Then, this calculated supplyable amount is returned in response to the possible amount inquiry from the electric devices 102, 103, 104. In addition, when an activation reservation is entered, the scheduled use period of each electrical device is monitored, and power is secured so that the apparatus can be activated at the activation reservation time.

  Next, the procedure of the power control process in the power control system S2 configured as described above will be described with reference to the flowchart of FIG. Note that FIG. 2 is referred to for the configuration of the electric device 102 (103, 104).

  When this power control process is started and the power switch of the electric device terminal C is turned on (step S601), only the communication control unit 204 is supplied with power and the communication control unit 204 is activated (step S602).

  The communication control unit 204 notifies the power control server 101 of the power to be used, inquires about the currently available power through the power line L, and can supply the power necessary for the operation of the electric device 102 (103, 104). It waits until it will be in a state (step S603, step S604).

  When the electric power necessary for the operation of the electric device 102 (103, 104) is ready to be supplied, is the electric device 102 (103, 104) executed in the high-speed mode in which much electric power is used based on the available electric power? Then, it is determined whether to execute in the low power mode with reduced power (step S605).

  If it is determined in step S305 that the operation in the high speed mode is possible, the power control server 101 is notified of the power necessary for the operation in the high speed mode (step S606), and then the communication control unit 204 shuts off the power. The device 205 is operated to supply power to the main operation unit 206 (step S607), and the main operation unit 206 executes the operation (step S608).

  On the other hand, when power sufficient for the operation in the high speed mode cannot be supplied in step S605 and the operation is performed in the low power mode, the power control server 101 is notified of the power necessary for the operation in the low power mode ( After step S609), the communication control unit 204 operates the power breaker 205 to supply power to the main operation unit 206 (step S610), and the main operation unit 206 executes the operation (step S611).

  When the operation is finished (step S612), it is detected whether or not the activation timer of the electric device 102 (103, 104) is set. When the activation timer is set, the power control server 101 is activated with the activation time. The power control server 101 is notified of the required planned power sometimes (step S617), the standby mode is entered (step S614), and the planned power usage in the standby mode is notified to the power control server 101 (step S615).

  After that, when there is an operation instruction from the user or when the activation time set by the timer is reached, the power control server 101 is inquired of the power that can be used through the power line L and is necessary for the instructed operation. Wait until power can be supplied (step S603, step S604).

  According to the power control system S2 according to the second embodiment, it is possible to predict when the electric devices 102, 103, and 104 will operate on the power control server 101 side even when the timer is started by a timer. It is possible to take measures to limit power, such as stopping electrical equipment. In addition, various recorders, recorders, rice cookers, etc. are assumed as the electric devices that operate with the timer, but even if these electric devices are started with the timer at the set time, the entire system is due to excessive power consumption. Can be prevented from going down. In addition, when the electric devices 102 to 104 are operating, it may not be possible to perform a normal stop or switch control to an operation mode with low power consumption, but it is necessary to reduce power as in the past. At this point in time, there is no one-way power cut or low power control instruction to the electric devices 102 to 104 regardless of the state of the devices. Absent.

  Next, the power control server SE according to the third embodiment will be described with reference to FIG. 7 and FIG.

  The configuration of the power control server SE can also be applied to the power control system S1 according to the first embodiment and the power control server 101 of the power control system S2 according to the second embodiment. .

  The power control server SE includes a power meter 702 that monitors current power consumption, a power breaker 703 that cuts off power supply when an overcurrent occurs, and a communication data combination that couples communication data to the power line L to perform power line communication. Unit 704 and a power control unit 705 that performs power control of the electric devices 102, 103, and 104 (see FIGS. 1 and 5) connected to the power line L.

  The power control calculation unit 705 includes a communication control unit 706 that performs communication via the power line L and a power control table 707.

  The power control table 707 corresponds to the table 105 of the first embodiment and the table 505 of the second embodiment.

  The power control calculation unit 705 updates the scheduled use power notified from the electric devices 102, 103, and 104 connected to the power line L in the table 707, and the currently used power amount and power obtained from the power meter 702 Based on the control table 707, the amount of power that can be used is notified to the inquired electric device 102 (103, 104).

  The operation procedure of the power control server SE configured as described above will be described based on the flowchart of FIG.

  When the power control server SE is notified of the update of the scheduled power usage amount from the electric device 102 (103, 104) (step S801), the corresponding electric device 102 (103, 104) is registered in the power control table 707. If the corresponding device is not registered in the power control table 707, the device is additionally registered in the power control table 707, and then the power control table 707 information is updated (steps S805 and S806). Step S807).

  When an inquiry about available power from the electrical device 102 (103, 104) occurs (step S802), whether or not a timer start reservation is registered in the power control table 707, the current power meter value, Based on the total amount of power scheduled to be used from each device, the amount of power that can be used is notified to the electrical device (steps S803 and S804).

  Here, the amount of power that can be used by electrical equipment is

  Usable power amount of electrical equipment = [Power supply upper limit]-[Scheduled power amount sum from each device or the larger value of power meter]-[Sum of scheduled power when timer starts]

  Each value is substituted for and calculated (step S804).

  As another embodiment, regarding the timer start reservation, the current electrical device uses power and manages the current time, and calculates the power that can be supplied at the time of start by the timer. Good.

  Next, a power control system S3 according to a fourth embodiment will be described with reference to FIGS.

  First, in the block diagram of FIG. 9, a multi-function printer (printing apparatus) P capable of power line communication and the electric devices 103 and 104 are connected via the power line L so that these devices operate stably. The power control server 101 manages the power load of the power line L.

  The multi-function printer refers to a multifunction printer (MFP) equipped with a copy function, a fax function, a scanner function, a communication function, etc. in addition to a print function.

  When the power used by the multifunction printer P1 and the electrical devices 102, 103, 104 changes due to a change in operation, etc., communication is performed with the power control server 101 via the power line L, and how much power is currently used. Whether or not operation is possible is determined as an “inquiry of available power amount”, and based on the possible power supply amount returned from the power control server 101, whether or not the operation is possible and the operation mode (operation mode) are determined. After notifying the power control server 101 of the scheduled power usage amount, the operation is started.

  In addition, the power control server 101 sets an upper limit value F that can be supplied to the power line L in advance, and can supply the power control server 101 in accordance with the scheduled power usage amount information from each of the electric devices 102, 103, and 104 connected to the power line L. A table 120 for calculating the amount of electric power is returned, and the suppliable amount G calculated in response to an inquiry about the usable amount from the electric devices 102, 103, 104 is returned.

  Next, a configuration example of the multifunction printer P1 connected to the power control system S3 according to the fourth embodiment will be described with reference to the block diagram of FIG.

  The multifunction printer P1 performs power line communication via the power line L, determines an internal operation mode (operation mode), and determines a power to be supplied to each function. It comprises a functional unit 1202 that is an aggregate of functional block units (image processing unit 1207, FAX unit 1208, scanner unit 1209, and printing unit 1202) that realize various functions of the printer.

  The apparatus control unit 1201 extracts communication information from the power line L that is also used as a communication line, and enables the communication data combining unit 1203 that superimposes communication information and the supplied power to be used inside the multi-function printer P1. The power supply unit 1204 that performs AC-DC conversion and generates each internal voltage level, and the control command is determined from communication data from the outside such as the power line L or USB, and the amount of power that can be supplied to the power control server 101 An inquiry is made, the operation mode in the multi-function printer P1 is determined from the information from the power control server 101 and the input control command, and necessary function block units (image processing unit 1207, FAX unit 1208, scanner) Control unit 12 configured by a microcomputer or the like that performs power supply control on the unit 1209 and the printing unit 1202). 5 and a power breaker (breaker) 1206 that cuts off the power supplied to each functional block unit (image processing unit 1207, FAX unit 1208, scanner unit 1209, printing unit 1202) when unnecessary. Yes.

  The function unit 202 includes a drawing image processing unit 1207a that performs image processing so that print data is drawn based on a drawing command and scan data conforms to the print data, and a hard disk, a memory, and the like that store the result. An image processing unit 1207 including a storage unit 1207b, and a FAX unit 1208 including a communication processing unit 1208b that performs communication processing via an interface (IF) 1208a with an external FAX apparatus and a communication line 1300 such as a telephone line. A scanner unit 1209 and a printing unit 1210 are included.

  The scanner unit 1209 includes an image input unit (not shown) such as a CCD, a lamp 1209a that performs exposure, various motors 1209b of a driving system such as a paper feed mechanism, a data input control unit 1209c that controls scanned data, and the like. ing.

  The printing unit 1210 is a printer engine mounted according to the type of printer. For example, in the case of a laser printer system, a fixing unit 1210a, a developing unit 1210b, various motors 1210c of a driving system that performs paper feeding, and the like. It is configured.

  Next, with reference to FIGS. 11 to 13, a processing procedure of power control processing (first embodiment) performed in the power control system S <b> 3 having the above configuration will be described.

  First, the processing procedure of the power control process when the multifunction printer P1 is turned on will be described with reference to the flowcharts of FIGS.

  When the power control process is started and the power switch of the multi-function printer P1 is turned on (step S1301), power is supplied only to the apparatus control unit 1201 and the communication function is activated (step S1302). The control device 1205 inquires of the power control server 101 about currently available power through the power line L, and waits until power necessary for initialization of the multi-function printer P1 becomes available (steps S1303 and S1304).

  When the power necessary for initialization of the multi-function printer P1 is ready to be supplied, it is executed in the high-speed mode that uses a lot of power for initialization based on the amount of available power, or in the low-power mode with reduced power It is determined whether or not to perform (step S1305).

  If it is determined in step S1305 that initialization is possible in the high-speed mode, the power control server 101 is notified of the amount of power required for initialization in the high-speed mode (step S1306). 1206 is operated to supply power to the function block units (image processing unit 1207, FAX unit 1208, scanner unit 1209, printing unit 1202) in the function unit 202 all at once (step S1307), and initialization is executed. (Step S1308).

  When the initialization is completed (step S1309), it is determined whether or not an operation instruction from the user is generated (step S1314). If it is generated, the process proceeds to the processing of the corresponding function. If not, the process proceeds to the standby process in FIG.

  On the other hand, when it is not possible to secure a sufficient amount of power for initialization in the high speed mode in step S1305 and the initialization is performed in the low power mode, the power control server 101 is notified of the power required for initialization in the low power mode. After (step S1310), the control device 1205 activates the power breaker 1206 to each function block unit (image processing unit 1207, FAX unit 1208, scanner unit 1209, printing unit 1202) inside the function unit 202. Power is supplied in chronological order and initialization is performed for each function. (Step S1311, Step S1312, Step S1313).

  In this low power mode, power consumed instantaneously can be suppressed by operating in time series for each function, but the processing time is slower than in the high speed mode. At this time, the electric power consumed instantaneously may be suppressed by slowly rotating the motor or slowing the heater temperature.

  Next, a processing procedure of standby processing will be described with reference to the flowchart of FIG.

  As for standby processing, in the present embodiment, there are two states of “standby mode 1” in which power is supplied and processing is not performed, and “standby mode 2” in which unnecessary power is cut off internally. Will be described.

  When this standby process is started, if an operation instruction from the user is not detected, the process proceeds to standby mode 1 (step S1315).

  At that time, the power control server 101 is notified of the amount of power when no operation occurs in the power supply state of the function that has been operating until then (step S1316).

  In that state, when there is an instruction within a certain time waiting for an operation instruction from the user, the process shifts to the processing of the corresponding function, and if there is no instruction, the process shifts to the standby mode 2 (step S1317, step S1318, step S1319).

  When the standby mode 2 is entered, the control device 1205 stops the power supply of unnecessary portions other than the device control unit 1201 (step S1320).

  At this time, the power supply is not stopped for the FAX unit 1208 such as the one that requires constant power supply.

  After the internal power is stopped, the power control server 101 is notified of the amount of power used in the standby mode 2 (step S1321), and an operation instruction from the user is awaited (step S1322).

  Next, a processing procedure of power control processing when the power is turned off will be described with reference to the flowchart of FIG.

  First, in step S2322, the power off button or the like is operated, and the device control unit 1201 stops power supply other than the device control unit 1201 (step S2323), and then the power amount used by the device control unit 1201 is changed to the power control server 101. Is notified (step S2324), and the power supply of the device control unit 1201 is stopped (step S2325).

  As a result, even when the power is turned on next time, it is possible to prevent the entire system from going down due to insufficient power supply.

  Next, a processing procedure of power control processing (second embodiment) at the time of printing / FAX reception of the multi-function printer P1 will be described based on the flowchart of FIG.

  When this process is started, a print request is accepted (step S401), the power control server 101 is inquired about the amount of power that is currently available (step S402), and the process proceeds to step S403.

  In step S403, it is determined which of the image processing unit 1207 and the printing unit 1210 can be used. If it is determined that both the image processing unit 1207 and the printing unit 1210 can be used (step S403a), step S419 is performed. When it is determined that only the image processing unit 1207 is usable (step S403b), the process proceeds to step S404, and when it is determined that neither the image processing unit 1207 nor the printing unit 1210 is usable (step S403b). In step S403c, the process returns to step S402.

  In step S404, the image processing unit 1207 notifies the power control server 101 of the amount of power scheduled to be used. In step S405, image processing is started, and the process proceeds to step S406.

  In step S406, it is determined whether or not the image processing is completed. If “No”, the process waits until it is completed, and if “Yes”, the process proceeds to step S407.

  In step S407, the generated print image data is stored in a predetermined storage area of the storage unit 1207b, and then the process proceeds to step S408. The power control server 101 is inquired about the amount of power that is currently available, and then step S409. Migrate to

  In step S409, it is determined whether the amount of power is available for the image processing unit 1207 and the printing unit 1210. If “Yes”, the process proceeds to step S413, and if “No”, step S410 is performed. The process proceeds to the standby mode 1 and notifies the power control server 101 of the scheduled power consumption (step S411), and then proceeds to step S412.

  In step S412, it is determined whether or not a certain time has elapsed. If “No”, the process waits until the time elapses. If “Yes”, the process returns to step S408 to continue the process.

  In step S413, the printing unit 1210 notifies the power control server 101 of the amount of power scheduled to be used, and then the process proceeds to step S414. The warming up of the printing unit 1210 is started, and the process proceeds to step S415.

  In step S415, it is determined whether or not the warm-up of the printing unit 1210 has been completed. If “No”, the process waits until it is completed. If “Yes”, the process proceeds to step S416 to start printing. .

  Next, in step S416, it is determined whether or not printing has been completed. If “No”, the process waits until completion, and if “Yes”, it is determined whether or not there is an operation instruction from the next user. Is done.

  Then, when the determination result is “Yes”, the process proceeds to a process of executing each functional unit, and when the determination result is “No”, the process proceeds to the above-described standby process (see the flowchart of FIG. 12).

  On the other hand, if the determination in step S403 has shifted to step S419, the image processing unit 1207 and the printing unit 1210 notify the power control server 101 of the power amount scheduled to be used, and then the process proceeds to step S420.

  In step S420, image processing by the image processing unit 1207 and warm-up in the printing unit 1210 are started, and the process proceeds to step S421.

  In step S421, it is determined whether or not image processing and warm-up have been completed. If “No”, the process waits until completion, and if “Yes”, the process proceeds to step S416.

  Accordingly, usable functions of the image processing unit 1207 and the printing unit 1210 can be activated according to the amount of power that can be used. Further, it is possible to prevent a situation in which the power consumption is excessive due to the simultaneous use of the image processing unit 1207 and the printing unit 1210 and the entire system goes down.

  Next, the processing procedure of the power control process (third embodiment) when using the scanner / FAX of the multi-function printer P1 will be described based on the flowchart of FIG.

  When this process is started, a scan and copy request is accepted (step S501), the power control server 101 is inquired about the amount of power currently available (step S502), and the process proceeds to step S503.

  In step S503, it is determined which of the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 can be used, and if all of the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 are determined to be usable ( In step S503a), the process proceeds to step S521. When it is determined that only the scanner unit 1209 and the image processing unit 1207 are usable (step S503b), the process proceeds to step S504, and the scanner unit 1209 and the image processing unit 1207 use them. If it is determined that it is not possible (step S503c), the process returns to step S502.

  In step S504, the scanner unit 1209 and the image processing unit 1207 notify the power control server 101 of the power amount scheduled to be used. In step S505, scanning and input image processing are started, and the process proceeds to step S506.

  In step S506, it is determined whether or not the image processing is completed. If “No”, the process waits until the process is completed. If “Yes”, the process proceeds to step S507.

  In step S507, the generated print image data is stored in a predetermined storage area of the storage unit 1207b, and then the process proceeds to step S508 to determine whether there is a copy request.

  If the determination result is “No”, the process proceeds to step S514, the image generated is transferred to an external personal computer, etc., and then the process proceeds to the above-described standby process (see the flowchart in FIG. 12).

  If the determination result is “Yes” in step S508, the process proceeds to step S509, the power control server 101 is inquired about the amount of power that is currently available, and then the process proceeds to step S510.

  In step S510, it is determined whether the amount of power that can be used by the printing unit 1210 is determined. If “Yes”, the process proceeds to step S515, and if “No”, the process proceeds to step S511. The process proceeds to the standby mode 1 and notifies the power control server 101 of the scheduled power consumption (step S512), and then proceeds to step S513.

  In step S513, it is determined whether or not a predetermined time has elapsed. If “No”, the process waits until it elapses. If “Yes”, the process returns to step S509 to continue the processing.

  In step S515, the printing unit 1210 notifies the power control server 101 of the power amount scheduled to be used, and then the process proceeds to step S516. The warming up of the printing unit 1210 is started, and the process proceeds to step S517.

  In step S517, it is determined whether or not the warm-up of the printing unit 1210 has been completed. If “No”, the process waits until it is completed. If “Yes”, the process proceeds to step S518 to start printing. .

  Next, in step S519, it is determined whether or not printing has been completed. If “No”, the process waits until completion, and if “Yes”, it is determined whether there is an operation instruction from the next user. Is done.

  Then, when the determination result is “Yes”, the process proceeds to a process of executing each functional unit, and when the determination result is “No”, the process proceeds to the above-described standby process (see the flowchart of FIG. 12).

  On the other hand, if it is determined in step S503 that all of the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 are usable, the process proceeds to step S521, where the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 are used. Notifies the power control server 101 of the amount of power scheduled to be used before proceeding to step S522.

  In step S522, scanning by the scanner unit 1209, image processing by the image processing unit 1207, and warm-up in the printing unit 1210 are started, and the process proceeds to step S523.

  In step S523, it is determined whether or not scanning, image processing, and warm-up have been completed. If “No”, the process waits until completion, and if “Yes”, the process proceeds to step S518.

  Accordingly, usable functions of the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 can be activated according to the amount of power that can be used. In addition, the simultaneous use of the scanner unit 1209, the image processing unit 1207, and the printing unit 1210 can prevent a situation in which the entire system is down due to excessive power consumption.

  Next, with reference to FIGS. 16-18, electric power control system S4 which concerns on 5th Embodiment is demonstrated.

  The same configurations as those of the power control system S1 according to the first embodiment, the power control system S2 according to the second embodiment, and the power control system S3 according to the third embodiment are the same. Detailed description will be omitted.

  First, in the block diagram of FIG. 16, the power control system S4 includes a printing apparatus (printer) P2, a power control server 101, and a power line L that connects them.

  The printing apparatus P2 includes a function A unit 3004 including a display system circuit 3009 and a communication system circuit 3010, a function B unit 3005 including an image processing circuit 3011 and a motor system drive circuit, a function power saving mode control unit 3006, From the power control unit 3007 that controls the power saving mode of the function A unit 3004 and the function B unit 3005, and the cutoff circuit 3008 that cuts off the power to the function A unit 3004 and the function B unit 3005 under the control of the power control unit 3007 Composed.

  Note that this embodiment mode describes a case where the function section is divided into a function A section 3004 and a function B section 3005. However, the display system circuit 3009, the communication system circuit 3010, the image processing circuit 3011, and the motor system drive circuit 3012 are included. It is also possible to divide into four functional units individually.

  The power control server 101 supplies power to the cutoff circuit 3008 of the printing apparatus P2 through the connected power line L and notifies the power control unit 3007 of the usable power capacity.

  The power control unit 3007 determines whether the printing apparatus P2 can be normally activated, activated in the power saving mode, or only performs power supply of some functions based on the amount of power related to the notification of the usable power capacity, The determination result is transmitted to the power saving mode control unit 3006 and the cutoff circuit 3008.

  The power saving mode control unit 3006 instructs the function A unit 3004 and the function B unit 3005 to start in normal operation when the result of determination from the power control unit 3007 is normal activation.

  When the determination result is the power saving mode, the function A unit 3004 and the function B unit 3005 are instructed to start in the power saving mode.

  Specific operations in the power saving mode include, for example, lowering the clock frequency, lowering the backlight voltage of the display system circuit 3009 of the function A unit 3004, or motor rotation speed of the motor system drive circuit 3012 of the function B unit 3005. It may be possible to lower the value.

  Further, by dividing the function into the function A unit 3004 and the function B unit 3005, the activation in the power saving mode can be individually performed for each function, thereby enabling fine control.

  The cutoff circuit 3008 serves as a switch, and supplies power to the function A unit 3004 and the function B unit 3005 when the determination result of the power control unit 3007 can be normally activated.

  When it is determined that only the power supply for some functions can be activated, power is supplied to only one function. For example, as a specific example of operation, in a situation where only display on the liquid crystal panel is necessary and the function B unit 3005 side is not necessary, the cutoff circuit 3008 supplies power only to the function A unit 3004 side. When the amount of power that can be used is so small that it cannot be activated only by power supply of some functions, the cutoff circuit 3008 does not supply power to the function A unit 3004 and the function B unit 3005, and the printing apparatus P2 remains powered off.

  Next, the procedure of the power control process performed in the power control system S4 having the above configuration will be described with reference to the flowchart of FIG.

  First, when the printing apparatus P2 is activated, preparation for activation of the printing apparatus P2 is started in step S700, the process proceeds to step S701, and a notification of the amount of usable electric power is received from the power control server 101.

  Next, in step S702, it is determined whether or not the usable power amount is less than or equal to the power consumption required for the normal activation of the printing apparatus P2. If the determination result is “Yes”, the process proceeds to step S703 and the printing apparatus. P2 is activated in the normal mode and the process is terminated.

  If “No” is determined in step S702, the process proceeds to step S704 to determine whether or not the power saving mode can be started. If the determination result is “Yes”, the process proceeds to step S705. The printing apparatus P2 is activated in the power saving mode, and the process ends.

  On the other hand, if “No” is determined in step S704, the process proceeds to step S706, where it is determined whether the printing apparatus P2 can start only some functions, and if possible, the process proceeds to step S707. Then, the printer P2 is activated by supplying power to only a part of the functions, and then the process is terminated.

  On the other hand, if it is determined in step S706 that activation cannot be performed, the activation is not performed in the power-off state, the process returns to step S700, and the value of the usable power amount notified thereafter increases until the activation becomes possible. Repeat the process and wait.

  FIG. 18 is a table showing specific examples of the power consumption for each of the three printing apparatuses P2 (I, B, C), the power consumption for each function, and the power consumption in the power saving mode.

  With reference to the table of FIG. 18, in the power control system S4 according to the present embodiment, the activation patterns of the printing apparatuses A, B, and C with respect to the usable power amount will be described.

  In this example, it is assumed that the notification of usable electric energy is 25 W.

  In the case of this amount of power (25 W), the printing apparatus A can be normally started because the power consumption value for normal startup is 15 W, which is 25 W or less.

  Further, the printing apparatus B is 35 W and the printing apparatus C is 50 W, both of which exceed 25 W, and therefore both cannot be normally started.

  Further, since the total power consumption of the power saving mode of the function A part and the function B part of the printing apparatus B is 24 W and 25 W or less, the power saving mode can be activated.

  On the other hand, since the power consumption in the power saving mode is 35 W in total, the printing apparatus C exceeds 25 W and cannot be activated in the power saving mode.

  However, since the power consumption of only the function A unit is 20 W, it is possible to start only the function A unit by supplying power only to the function A unit.

  Thus, in the past, when the rated power amount is exceeded when the printing apparatus is activated, the power is unilaterally cut off by the power control server apparatus or the like, and the printing apparatus cannot be activated at all. In the power control system S4 according to the present embodiment, the printing device P2 side knows the surplus amount up to the usable power capacity, and accordingly the printing device P2 side stops activation in the power saving mode or partially unnecessary functions. In this state, it is possible to perform fine power control for each function such as starting only necessary functions.

  Furthermore, if it is expected that the power amount determined during the operation as well as the start-up by the printing device P2 is voluntarily controlled, the power is switched to the power saving mode or the function is partially stopped. A reduction control of the amount is possible.

  In addition, it is possible to perform control so as not to reach the target power consumption by selecting the start-up method according to the usable power capacity, as determined by the printing apparatus P2, and the control itself is simple. .

  Further, when the determined amount of power is set as a power saving target value, it can also function as a power saving system.

  Also, even when there are many printing apparatuses that do not support control over the available power amount notification, the system according to the present embodiment can be configured, and power control can be performed using only the corresponding printing apparatus.
