Description

  The present invention relates to an electric device, an electric device system, and an electric device control method capable of cooperatively controlling power consumption when a plurality of electric devices are electrically connected to one power circuit breaker.

  Multi-function peripherals (hereinafter referred to as MFP (Multi Function Peripheral)) that contain two or more functions such as copy, printer, scanner, and fax in a single housing are more space-saving than single-function devices. Multifunctional. For this reason, it is very convenient for users, and MFPs are beginning to spread rapidly in the business market and home market.

  In general, an MFP executes a process with a large power consumption such as warming up of a fixing heater and image quality maintaining operation of an electrophotographic process at startup (warm-up). For this reason, many MFPs consume a large amount of power when activated.

  An increasing number of electric devices such as MFPs that require multi-functionality are accompanied by high power consumption especially at the time of startup as a price for pursuing multi-functionality.

  The large power consumption at the time of starting up the electric device causes the following problems, particularly when a plurality of electric devices are used at the same time. For example, when a plurality of MFPs are arranged in a concentrated manner in a location, when a power failure occurs, all MFPs simultaneously perform a warm-up operation when the power failure is restored. As a result, excessive power consumption exceeding the allowable power of the power breaker (hereinafter referred to as breaker) may occur due to large power consumption at startup. In this case, the breaker is activated and power is lost again. Problem arises. In addition, even when a power failure does not occur, a large current is consumed temporarily, and thus there is a problem that the power use efficiency is poor.

  Conventionally, this type of technology for suppressing excessive power consumption by an electric device such as an MFP is disclosed in Japanese Patent Laid-Open Nos. 10-94199 (Patent Document 1) and 2002-355212 (Patent Document 2). There is something that was done.

  The communication system disclosed in Patent Literature 1 includes a breaker device and a plurality of electrical devices. When each electrical device requires power, first, a power request signal with an ID unique to the device is transmitted to the breaker device. The breaker device predicts the total power usage based on the allowable power amount, and attaches the ID attached to the power request signal that has received the signal notifying that the power usage is permitted or the signal notifying that the power usage is not permitted. Each electric device determines whether it is a signal for its own device based on the received signal ID, and starts power consumption only when it receives a power use permission notification signal. . According to this communication system, since the total power consumption can be controlled based on the allowable power amount, it is possible to prevent the power supply from being interrupted by the power breaker (hereinafter referred to as breaker failure).

In addition, the electric machine apparatus disclosed in Patent Document 2 includes an L1 and N power supply line (breaker) and a L2 and N power supply line (breaker), which are largely divided into three-phase alternating current into single-phase alternating current. In the case where the power supply system is configured by, an electric apparatus such as an electrophotographic apparatus is divided into a plurality of blocks, and a high frequency signal is transmitted and received between each block via a power line, and the attenuation of the high frequency signal is performed. Based on the amount and propagation delay time, it is determined whether each block is connected to the same power supply line (breaker) (grouping), and a plurality of blocks are connected to the same power supply line (breaker) In some cases, control such as limiting power supply is performed. For this reason, it is possible to assign an appropriate power supply line (breaker) to each block, and use electrical equipment that requires a large current even in indoor wiring such as general offices and homes with low allowable power consumption. Can do.

  In the technique disclosed in Patent Document 1, a so-called intelligent function (such as a function for transmitting / receiving data or a function for controlling an electric device) is required for the breaker. For this reason, it is difficult to replace with an existing breaker, and in an existing power system, it is necessary to remove the existing breaker and replace it with a breaker having an intelligent function, which lacks versatility.

  In the technique disclosed in Patent Document 2, it is determined whether or not each block is connected to the same breaker based on the attenuation amount and propagation delay time of a high-frequency signal transmitted and received via the power line. However, depending on the power supply system, there is not always a correlation between the line length of the power line and the breaker. For this reason, the reliability of the grouping judgment is poor.

  As a case where the correlation does not hold between the line length of the power line and the breaker, the following cases can be considered. For example, there are two breakers (breaker A and breaker B), segment A is constituted by electric device A1 and electric device A2 connected to breaker A, and segment B is constituted by electric device B1 connected to breaker B. In the case where the breakers A and B are close to each other, for example, when viewed from the electric device A1, the line length between the electric device A2 and the electric device B1 belonging to the segment B, which is another segment, is larger. In the meantime, there is a possibility that the length of the line through the two breakers will be shorter.

  Therefore, the conventional method of grouping for each connection breaker based on the attenuation amount and propagation delay time of the high-frequency signal transmitted / received via the power line is extremely unreliable and is not practical.

  The present invention has been made in consideration of the above-described circumstances, and can automatically and accurately group a plurality of electrical devices for each connection breaker, and control the power consumption of the electrical devices for each group.

And an in-execution signal receiving means for determining whether or not a signal indicating that the start-up operation is being executed, transmitted from the in-execution signal transmission means of the device, has been received.

  In order to solve the above-described problem, a multifunction machine according to the present invention is executing a startup operation in a multifunction machine having at least two types of functions of a copying function, a printer function, a facsimile function, and a scanner function. The in-execution signal transmitting means for transmitting a signal to the effect and the in-execution signal transmitting means of another electrical device electrically connected to each other via the power line are received to indicate that the starting operation is being performed. And an in-execution signal receiving means for determining whether or not.

The power breakers of the plurality of segments are electrically connected to each other via a power line, and a blocking filter configured to shield a signal transmitted by the electric device via the power line is provided near the power breaker. In preparation for this, a signal through the power line is not propagated from an electrical device in one segment to an electrical device in another segment by shielding with the blocking filter.

  On the other hand, in order to solve the above-described problem, the electrical device control method according to the present invention receives a signal indicating that the startup operation is being performed from other electrical devices that are electrically connected to each other via the power line. If the signal indicating that the startup operation is being executed is not received from the other electrical device, the startup operation is started. During the startup operation, the startup operation is being executed. A method comprising the step of transmitting a signal.

  Moreover, in order to solve the above-described problem, the electrical device control method according to the present invention transmits a signal indicating that the start operation is to be started, and from other electrical devices electrically connected to each other via the power line, It is determined whether or not a signal indicating that the activation operation is being performed is received, and if the signal indicating that the activation operation is being performed is not received from the other electrical device, the activation operation is started and the other It is determined whether or not a signal indicating that a start operation is to be started is received from the electrical device, and when the start operation is being performed and a signal indicating that a start operation is to be started is received from the other electrical device, A method comprising a step of transmitting a signal indicating that a start-up operation is being performed.

It is a flowchart which shows the procedure at the time of preventing a fall. In FIG. 5, reference numerals with numbers added to S indicate steps in the flowchart.

  Hereinafter, as an example, for the MFP 13 of the electric device system 1 shown in FIG. 1, the CPU 41 of the MFP 13 shown in FIG. 2 performs other electric devices (MFP 14, MFP 15 and copier 16) in the first power segment 10 that are the same segment. ) And the procedure for performing the start-up operation in cooperation with. For the MFP 14, the MFP 15, and the copier 16, the description of the same configuration and operation as the MFP 13 is omitted.

  First, in step S1, the MFP 13 receives an instruction to turn on the power by the user via the power switch 44 or the network connection means 48 or by automatic recovery from a power failure, and at least the CPU 41, the RAM 42, the ROM 43, and the nonvolatile memory. The energization of the means 49 is started.

  Next, in step S2, the index value determination unit 41a reads the value of SHDWN_SCSS stored in the nonvolatile storage unit 49, and determines whether this value is zero. If this value is zero, the process proceeds to step S3. On the other hand, if this value is not zero, such as 1, for example, the process proceeds to step S5. Next, in step S3, the index value changing unit 41b changes the value of SHDWN_SCSS stored in the nonvolatile storage unit 49 to 1.

  Next, in step S4, each unit warm-up control unit 41c transmits an instruction signal to be warmed up to the job execution unit 46, and the printer unit 46a, the copy unit 46b, and the scanner unit 46c constituting the job execution unit 46 Warm-up is started, and warm-up of a fixing device, a photoconductor and a developing device that require high power is started. Then, each part warm-up control means 41c receives a signal indicating that the warm-up is completed from each part of the printer section 46a, copy section 46b, and scanner section 46c constituting the JOB execution means 46, and proceeds to step S6.

  On the other hand, in step S5, the cooperative warm-up control unit 41d performs communication (PLC: Power Line Communication, etc.) via the power line with other electric devices (MFP 14, MFP 15, and copier 16) in the first power segment 10. The startup operation (warm-up) is performed cooperatively.

  Next, the procedure for performing this cooperative warm-up will be described.

  FIG. 6 is a subroutine flowchart showing the procedure of the cooperative warm-up executed by the cooperative warm-up control means 41d of the MFP 13 in step S5 of FIG. For the MFP 14, the MFP 15, and the copier 16, the description of the same configuration and operation as the MFP 13 is omitted. In FIG. 6, reference numerals with numbers added to S indicate steps in the flowchart.

  First, in step S51, the request signal transmission unit 41d1 of the cooperative warm-up control unit 41d transmits a WarmUP_Request message from the power line connection unit 45 via the power line as a signal indicating that the activation operation is to be started.

  The signal transmitted through the power line is transmitted to all the electric devices in the first power segment 10, but is filtered by the blocking filters 31 and 32 in the electric devices in the second power segment 20. Therefore, do not reach. For this reason, by arranging the blocking filters 31 and 32 in the vicinity of the segment breaker, a segment is constituted by electric devices connected to the same breaker, and mixing of signals via power lines with other segments is prevented. Is possible. It becomes possible for the electrical devices in the system to perform a startup operation in cooperation.

  Next, in step S52, the in-execution signal receiving unit 41d2 determines whether or not the WarmUP_Executing message, which is a signal indicating that the activation operation is being executed, is received from the in-execution signal transmission unit of another electrical device. If received, the process proceeds to step S53. On the other hand, if not received, the process proceeds to step S56.

  Next, in step S53, the random number generation means 41d3 generates a random number and gives this random number to the standby time calculation means 41d4.

  Next, in step S54, the standby time calculation unit 41d4 calculates the standby time Tw based on the random number received from the random number generation unit 41d3, and gives the value of the standby time Tw to the standby unit 41d5.

  Next, in step S55, the standby unit 41d5 causes the CPU 41 to wait for the standby time Tw received from the standby time calculation unit 41d4, and returns to step S52. For example, when 5 seconds is received as this Tw, at least 5 seconds is set as the determination interval as to whether or not the WarmUP_Executing message is received by the in-execution signal receiving unit 41d2 by the standby unit 41d5.

  On the other hand, in step S56, each part warm-up control means 41c transmits an instruction signal to be warmed up to the JOB execution means 46. As a result, the warm-up of the printer unit 46a, the copy unit 46b, and the scanner unit 46c constituting the JOB execution unit 46 is started, and the warm-up of the fixing device, the photosensitive member, the developing device, and the like that require high power is started. Become.

  Next, in step S57, the request signal receiving unit 41d6 determines whether or not a WarmUP_Request message that is a signal indicating that the activation operation is to be started is received from the request signal transmitting unit of another electrical device. If received, the process proceeds to step S58. On the other hand, if not received, the process proceeds to step S59.

  Next, in step S58, the in-execution signal transmission unit 41d7 transmits a WarmUP_Executing message, which is a signal indicating that the activation operation is being performed, and returns to step S57.

  On the other hand, in step S59, each part warm-up control unit 41c determines whether or not the warm-up completion signal has been received from each of the printer unit 46a, copy unit 46b, and scanner unit 46c constituting the JOB execution unit 46. To do. If not received, the process returns to step S57 to continue the warm-up of each part. On the other hand, if it has been received, the series of procedures for cooperative warm-up of the MFP 13 ends, and the process proceeds to step S6 in FIG.

  Next, in step S <b> 6, the power OFF instruction determination unit 41 e determines whether there is an instruction (normal termination instruction) that the user should turn off the power of the MFP 13 via the input unit 47 or the network connection unit 48. If there is no normal end instruction, the process proceeds to step S7. On the other hand, if there is an instruction, the process proceeds to step S11.

  Next, in step S7, the job execution instruction unit 41f monitors the job execution means 46 and determines whether there is a job to be executed. If there is a job to be executed, for example, if there is a print waiting job in the printer unit 46a, the process proceeds to step S8. On the other hand, if not, the process returns to step S6.

  Next, in step S8, the job execution instruction unit 41f monitors the job execution unit 46, and determines whether each of the printer unit 46a, the copy unit 46b, and the scanner unit 46c constituting the job execution unit 46 can execute the job. . For example, when there is a print waiting job in the printer unit 46a, it is determined whether the printer unit 46a can execute the job. If the job cannot be executed, the process proceeds to step S9. On the other hand, if the job can be executed, the process proceeds to step S10.

  The case where the job cannot be executed refers to a case where the MFP 13 is in a state (state) generally called a power saving mode, a sleep mode, or a power saving mode after a predetermined time has elapsed after activation (warm-up) is completed. . This power saving mode state can occur when the user has set in advance to shift to the power saving mode when the time during which the JOB is not executed is long after the respective parts are warmed up by the specification or by the user via the input means 47.

  Next, in step S9, each unit warm-up control unit 41c transmits an instruction signal to be warmed up to the job execution unit 46, and the printer unit 46a, the copy unit 46b, and the scanner unit 46c that constitute the job execution unit 46. Start warm-up. Then, each part warm-up control means 41c receives a signal indicating that the warm-up is completed from each part of the printer section 46a, copy section 46b, and scanner section 46c constituting the JOB execution means 46, and proceeds to step S6. At this time, for example, when there is a print waiting job in the printer unit 46a, only the printer unit 46a may be warmed up.

  Next, in step S10, the job execution instruction unit 41f instructs the job execution means 46 to execute the job, and returns to step S6. For example, if the printer unit 46a has a job waiting to be printed, the printer unit 46a is instructed to perform print processing.

  In the series of steps from Step S7 to Step S10, the steps described as being performed by the JOB execution instruction unit 41f of the CPU 41 may be performed by the JOB execution unit 46. In this case, the job execution unit 46 may be configured to have the function of the job execution instruction unit 41f. In other words, the job execution means 46 may be configured to have at least a function for determining whether there is a job to be executed and a function for determining whether each unit such as the printer unit 46a can execute the job.

  Next, in step S11, the index value changing unit 41b receives a notification that there has been a normal termination instruction from the power OFF instruction determining unit 41e, and changes the value of SHDWN_SCSS stored in the nonvolatile storage unit 49 to 0. To do. Therefore, if a power failure occurs between step S3 and step S11, the value of SHDWN_SCSS at the next startup will be 1, while if the power is turned off after a normal termination instruction, the next startup The value of SHDWN_SCSS at the time is 0.

  Next, in step S12, the power OFF execution unit 41g performs a series of shutdown processes of the MFP 13 such as storing required information in the RAM 42 in the nonvolatile storage unit 49.

  With the above procedure, in an electrical equipment system having a plurality of segments configured by connecting a plurality of electrical equipments to the same breaker, the electrical equipment in the same segment performs a startup operation in a coordinated manner, so that the segment breaker Breaker dropping can be prevented.

  The electrical equipment system 1 shown in FIG. 1 is provided with blocking filters 31 and 32 in the vicinity of a segment breaker. For this reason, for example, a signal transmitted from the electrical device group 12 in the first power segment 10 via the power line does not reach the electrical device group 22 in the second power segment 20. Therefore, the electrical device system 1 can automatically and accurately group electrical devices connected to the same breaker.

  In the description of the present embodiment, the blocking filters 31 and 32 can reliably attenuate the signal via the power line, and this signal does not reach the other segment from its own segment, but this attenuation is insufficient. In order to cope with this, each electric device may be provided with a general group determination function based on a signal attenuation amount or a signal delay time. Here, this group determination function refers to a function of discarding this signal as a signal from an electrical device belonging to another segment when the signal attenuation is a certain value or less or the signal delay time is a certain time or more. And

  Of course, if only segmentation is to be performed, the user may investigate the electrical equipment connected to the same breaker, and perform segmentation settings for each electrical equipment in advance by the user.

  In addition, each electrical device of the electrical device system 1 is in the same segment at the next start-up when a termination other than normal termination (abnormal termination such as termination due to a power failure or failure) is performed. It has a function of confirming each other's activation execution state by transmitting and receiving signals through the power line between electrical devices. For this reason, it is possible to prevent two or more electric devices from starting simultaneously in the same segment, and one unit is sequentially warmed up for each segment.

  Therefore, according to this electrical equipment system 1, for example, even when a plurality of electrical equipments are activated simultaneously at the time of recovery from a power failure, the possibility of exceeding the allowable power amount of the segment breaker is extremely low, and excessive power consumption in the same segment is achieved. Can be prevented, and breaker dropping can be prevented.

  In the description of the present embodiment, the cooperative warm-up is not performed at the next activation in the case of normal termination, but the cooperative warm-up may be performed in the normal termination. In this case, steps S2, S3, S4 and S11 may be omitted in the procedure shown in FIG. 5, and the procedure after step S6 may be performed after the transition to step S5 after step S1. In this case, cooperative warm-up is also performed at the next startup after normal termination. Therefore, for example, in the office, even when multiple MFPs connected to the same breaker are activated at the same time, such as when going to work in the morning, excessive power consumption can be suppressed, and an unexpected breaker failure can be prevented. be able to.

  In this embodiment, only one electric device can be activated in the same segment in the cooperative warm-up procedure, but a plurality of devices may be activated simultaneously within the allowable power amount range. For example, when three units can be activated simultaneously, in the determination by the in-execution signal receiving means 41d2, if the number of received WarmUP_Executing messages is two or less, activation of the own device is started.

  In the present embodiment, an example in which the electrical device system 1 is configured by two segments has been described. However, by installing a blocking filter for each segment, cooperative control only within the segment is possible. Therefore, the electrical equipment system 1 according to the present embodiment can be applied to any number of segments, and can provide the same operational effects as when there are two segments.

  FIG. 7 is a schematic block diagram showing a configuration example of the cooperative warm-up control means 41d in the second embodiment of the electrical equipment system according to the present invention.

  In the electrical equipment system 1A shown in the second embodiment, priorities are assigned in advance to electrical equipment groups in the same segment, and are activated in the order of the priorities. In this embodiment, only the configuration of the cooperative warm-up control means of each electric device (MFP 13 or the like) is different from the electric device system 1 shown in FIG. Since other configurations and operations are not substantially different from those of the electric device system 1 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

  The MFP 13 and other electrical devices (MFPs 14, 15, 23, 24, and 25, the copier 16 and the printer 26) have the same configuration as the MFP 13 except that the configuration of the job execution unit 46 is different. A description will be given, and description of other electrical devices will be omitted.

  As shown in FIG. 7, the cooperative warm-up control unit 41d includes at least a priority determination unit 41d21, an executing signal receiving unit 41d2, a random number generating unit 41d3, a waiting time calculating unit 41d4, a waiting unit 41d5, and an executing signal transmitting unit 41d7. Have

  The priority order determination unit 41 d 21 has a function of determining whether or not the priority order of the own device is the highest in the first power segment 10. In addition, the priority order determination unit 41d21 compares the priority order of the other electrical devices included in the WarmUP_Executing message received from the in-execution signal receiving unit 41d2 with the priority order of the own device. It has a function of determining whether it is one higher in the priority order of the machine.

  The in-execution signal receiving unit 41d7 has a function of transmitting a WarmUP_Executing message which is a signal for informing other electrical devices that the own device is executing the start-up operation. This message includes at least information on the priority set in advance in the own device, in addition to information indicating that the own device is performing the start-up operation.

  FIG. 8 is a subroutine flowchart showing another procedure of the cooperative warm-up executed by the cooperative warm-up control means 41d in step S5 of FIG. Steps equivalent to those in FIG. 6 are denoted by the same reference numerals, and redundant description is omitted.

  In advance, the user assigns a unique priority order within the same segment to the electrical equipment group within the same segment via the input means 47 and the like, and this priority order is stored in each electrical equipment.

  In step S521, the in-execution signal receiving unit 41d2 determines whether a WarmUP_Executing message, which is a signal indicating that the activation operation is being executed, is received from the in-execution signal transmission unit of another electrical device. If not received, the process proceeds to step S522. On the other hand, if received, the process proceeds to step S523.

  Next, in step S522, the priority order determination unit 41d21 determines whether or not the priority order of the own device is the highest in the first power segment 10. If it is the highest level, it is the first electrical device to be activated in the first power segment 10, and thus the process proceeds to step S56 to immediately start activation. On the other hand, if it is not the highest level, the process returns to step S521.

  On the other hand, in step S523, the priority order determination unit 41d21 receives the WarmUP_Executing message received by the in-execution signal reception unit 41d2, and extracts the priority order of other electrical devices that are currently activated included in this message. Then, the priority order determination means 41d21 compares the priority order of the other electrical equipment currently activated with the priority order of the own equipment stored in advance in the own equipment, and the priority order of the other electrical equipment is one higher. It is determined whether it hits.

  Here, the priority order of the other electrical devices being one higher means that the start of the own device may be started immediately after the start of the other electrical devices. Note that this does not mean that you are bound to represent an integer value.

  As a result of the determination, if the priority order of the other electrical devices is not one higher than the priority order of the own device, the process returns to step S521. On the other hand, if it is one higher level, the process proceeds to step S52 in order to start the start immediately after the start of the other electrical devices.

  In step S59, each part warm-up control unit 41c determines whether or not the warm-up completion signal has been received from each of the printer unit 46a, copy unit 46b, and scanner unit 46c constituting the JOB execution unit 46. To do. If not received, the process returns to step S58 in order to continue the warm-up of each part. On the other hand, if it has been received, the series of procedures for cooperative warm-up of the MFP 13 ends, and the process proceeds to step S6 in FIG.

  According to the above procedure, it is possible to start up the electrical devices in the order of priorities set in advance for the electrical device group in the same segment.

  The same effect as that of the first embodiment can also be obtained by the electrical apparatus system 1A according to the present embodiment.

  In addition, the electrical equipment system 1A according to the present embodiment prioritizes electrical equipment groups in the same segment and starts up in the order of the priorities. Therefore, according to the electrical equipment system 1A, electrical equipment with a high usage frequency (priority) can be used at an early stage, which is excellent in convenience.

  FIG. 9 is a schematic block diagram showing a configuration example of the cooperative warm-up control means 41d shown in FIG. 3 in the third embodiment of the electrical equipment system according to the present invention.

  The electrical equipment system 1B shown in the third embodiment determines the power allocation order (allocation order) in advance and allocates power to the electrical equipment in the same segment based on the allocation order in a time-division multiplexed manner. , All electric devices are activated simultaneously in parallel. In this embodiment, only the configuration of the cooperative warm-up control means of each electric device (MFP 13 or the like) is different from the electric device system 1 shown in FIG. Since other configurations and operations are not substantially different from those of the electric device system 1 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

  The MFP 13 and other electrical devices (MFPs 14, 15, 23, 24, and 25, the copier 16 and the printer 26) have the same configuration as the MFP 13 except that the configuration of the job execution unit 46 is different. A description will be given, and description of other electrical devices will be omitted.

  As shown in FIG. 9, the cooperative warm-up control unit 41d includes at least an allocation order determination unit 41d31, an executing signal receiving unit 41d2, a random number generating unit 41d3, a waiting time calculating unit 41d4, a waiting unit 41d5, and an executing signal transmitting unit 41d7. , An allocation time determination unit 41d32 and an activation completion notification unit 41d33.

  The allocation order determination unit 41 d 31 has a function of determining whether or not the power allocation order (allocation order) is the highest in the first power segment 10. Further, the allocation order determination unit 41d31 extracts the allocation order of other electrical devices that are currently activated included in the WarmUP_Executing message received from the in-execution signal reception unit 41d2. Then, the allocation order determination unit 41d31 compares the allocation order of the other electrical devices currently activated with the allocation order of the own device, and determines whether the allocation order of the other electrical devices is immediately above the own device. It has a function. In this determination, if the allocation order determination unit 41d31 receives a notification of completion of activation (activation completion notification) from the activation completion notification unit of another electrical device, the allocation completion determination unit 41d31 Remove the electrical device that sent the from the judgment target.

  The allocation time determination unit 41d32 has a function of determining whether or not the elapsed time from the start of each part warm-up has exceeded the power allocation time allocated to the own device.

  The activation completion notification means 41d33 has a function of transmitting information indicating that the warm-up of the own device has been completed (activation completion notification) together with information on the allocation order of the own device.

  The in-execution signal receiving unit 41d7 has a function of transmitting a WarmUP_Executing message which is a signal for informing other electrical devices that the own device is executing the start-up operation. This message includes at least information on the allocation order set in advance in the own device in addition to information indicating that the own device is performing the start-up operation.

  FIG. 10 is a subroutine flowchart showing still another procedure of the cooperative warm-up executed by the cooperative warm-up control means 41d in step S5 of FIG. Steps equivalent to those in FIG. 6 are denoted by the same reference numerals, and redundant description is omitted.

  First, an order for assigning unique power in the same segment (assignment order) to the electrical equipment group in the same segment is set in advance by the user via the input means 47 and the like, and this assignment order is stored in each electrical equipment. Let me. Further, this allocation order may be determined randomly by random numbers so as to be unique within the same segment.

  As a time-sharing method, a fixed length may be assigned so that all electric devices are treated equally, or priorities of electric devices may be set in advance and a long time may be assigned to a higher priority. .

  In step S531, the in-execution signal receiving unit 41d2 determines whether or not a WarmUP_Executing message, which is a signal indicating that the activation operation is being executed, is received from the in-execution signal transmission unit of another electrical device. If not received, the process proceeds to step S532. On the other hand, if received, the process proceeds to step S533.

  Next, in step S532, the allocation order determination unit 41d31 determines whether or not the allocation order of the own device is the highest in the first power segment 10. If it is the highest rank, the process proceeds to step S53. On the other hand, if it is not the highest level, the process returns to step S531.

  On the other hand, in step S533, the allocation order determination unit 41d31 receives the WarmUP_Executing message received by the in-execution signal reception unit 41d2, and extracts the allocation order of other electrical devices currently activated included in this message. Then, the allocation order determination unit 41d31 compares the allocation order of the other electrical devices currently activated with the allocation order of the own device stored in advance in the own device, and the allocation order of the other electrical devices is Determine whether it is directly above.

  Here, the allocation order of other electrical devices is directly above, from the viewpoint of the allocation order, there is no electrical device that has not been started up between itself and other electrical devices, and It means that the allocation order of other electrical devices is higher than the own device.

  As a result of this determination, if the allocation order of the other electrical devices is not immediately above the allocation order of the own device, the process returns to step S531. On the other hand, if it is directly above, the process proceeds to step S535 in order to start the start immediately after the start of the other electrical devices.

  On the other hand, in step S534, the standby unit 41d5 waits for the processing of the CPU 41 for the standby time Tw received from the standby time calculation unit 41d4, and proceeds to step S535. As a result, the highest electrical device in the segment in the segment waits for Tw from the time when the WarmUP_Executing message stops (when NO is determined in step S531), and then proceeds to step S535.

  The reason for this standby is only when power allocation has been completed as a cause of the message being interrupted (the allocation time of the lowest-ordered electrical device has been completed and all the electrical devices in the segment have received the same number of power allocations). Instead, step S531 may have been performed in the time lag of switching the power allocation from the electrical device other than the lowest allocation order to the other electrical devices. In order to eliminate the latter case, the CPU 41 waits for the waiting time Tw, and the process proceeds to step S535.

  Next, in step S535, the in-execution signal receiving unit 41d2 determines whether or not the WarmUP_Executing message, which is a signal indicating that the activation operation is being executed, is received from the in-execution signal transmission unit of another electrical device. If received, the process returns to step S533. On the other hand, if not received, the process proceeds to step S56.

  In step S536, the allocation time determination unit 41d32 determines whether the elapsed time from the start of warming up of each unit (step S56) exceeds the power allocation time allocated to the own device. If exceeded, the process returns to step S531. If not, the process proceeds to step S59.

  Next, in step S59, each unit warm-up control unit 41c determines whether or not the warm-up completion signal has been received from each unit of the printer unit 46a, copy unit 46b, and scanner unit 46c constituting the JOB execution unit 46. judge. If not received, the process returns to step S58 in order to continue the warm-up of each part. On the other hand, if it is received, the process proceeds to step S537.

  Next, in step S537, the activation completion notification means 41d33 transmits information indicating that the warm-up of the own device has been completed (activation completion notification) together with information on the allocation order of the own device. Upon receiving the activation completion notification, the allocation order determination unit of the other electrical device causes the MFP 13 that is the electrical device that has transmitted the activation completion notification to be excluded from the target in the allocation order determination (step S533). Then, the series of cooperative warm-up procedures of the MFP 13 ends, and the process proceeds to step S6 in FIG.

  By the above procedure, all electric devices can be activated in parallel by allocating power to the electric devices in the same segment in a time-division-multiplexed manner based on the allocation order set in advance for the electric device group. Is possible.

  The electric device system 1B according to the present embodiment can also obtain the same effect as that of the first embodiment.

  In addition, the electrical device system 1B according to the present embodiment allocates power to the electrical devices in the same segment in a time-division multiplexed manner so that all the electrical devices are activated simultaneously in parallel. Therefore, according to the electrical device system 1B, it is possible to substantially align the timing of completion of activation of all the electrical devices in the same segment, and in particular, the load on the electrical device that has been activated that may occur when only one unit is activated. It is possible to avoid the harmful effects of simultaneous concentration.
