In addition, the power consumption can be reduced according to the usage frequency of the user, and the function unit can be immediately used to shorten the startup time.

  In the present invention, when an operation instruction is received, the reception day and the reception time when the operation instruction is received are stored. The control means controls the transition between the operable state and the power saving state based on the reception day of the week and the reception time each time the stored reception day and reception time are reached. As a result, the state is shifted to the operable state or the power saving state according to the use state based on the operation instruction.

  In the present invention, when the receiving unit receives an operation instruction for power supply (power on) by the receiving unit, the control unit shifts a predetermined time zone before and after the operation instruction receiving time to an operable state. For example, the time zone of 30 minutes before and after the time when the power-on operation instruction is received is shifted to the operable state.

  In the present invention, when the receiving unit receives an operation instruction to stop power supply (power off) by the receiving unit, the control unit shifts a predetermined time zone before the operation instruction receiving time to an operable state. For example, the time zone of 1 hour before the time point when the power-off operation instruction is received is shifted to the operable state.

  In the present invention, when a predetermined period (for example, one month) has elapsed from the reception time of the operation instruction, the number of receptions based on the operation instruction is subtracted from the counted reception frequency. That is, an operation instruction that has passed for more than one month from the present time is excluded from the reception frequency. Thereby, even when a user's usage condition changes, power consumption is reduced according to a user's usage condition.

In the present invention, the reception time at which the operation instruction is received is stored , the reception frequency of the operation instruction is counted for a predetermined period and every predetermined time period, and according to the counted reception frequency, Controls the increase / decrease in the number of functional units that can be powered individually in the time zone.

  Hereinafter, a DVD recorder 100 as an example of an electric apparatus according to the present invention will be described with reference to the drawings illustrating an embodiment. FIG. 1 is a block diagram showing a main configuration of a DVD recorder 100 according to the present invention. In the figure, reference numeral 1 denotes a control unit constituted by a microprocessor. The control unit 1 loads the computer program stored in the storage unit 6 into the RAM 5 and executes it, thereby performing processing for controlling the power consumption of the entire DVD recorder 100.

  The DVD recorder 100 includes a CPU 8, a DVD 9, an HDD 10, a fan 11, a tuner 12, and the like, which are main functional components. The CPU 8 controls various functions of the DVD recorder 100 such as program recording, program reproduction, dubbing of recorded programs, and program reservation. The DVD 9 is used for recording a received program on a DVD disk and dubbing a program once recorded on the HDD 10 onto a DVD disk.

  The HDD 10 records a received program or a program reserved for recording in advance. The fan 11 discharges the heat generated inside the housing of the DVD recorder 100 to the outside, and suppresses the temperature rise inside. The tuner 12 includes, for example, a receiving circuit such as an analog broadcast or a digital broadcast. Based on the received signal, the tuner 12 reproduces a program on a liquid crystal monitor (not shown) and receives a signal received by an encoder (not shown). A desired program is recorded by converting it into a predetermined signal and recording it on the HDD 10 or the DVD 9.

  The CPU 8, DVD 9, HDD 10, fan 11, and tuner 12 are operated by electric power (for example, a predetermined DC voltage) supplied from the power supply unit 7. The power supply unit 7 supplies power to the CPU 8, the DVD 9, the HDD 10, the fan 11, and the tuner 12 independently based on a control signal input from the control unit 1. For example, the power supply unit 7 can stop supplying power to the DVD 9 and the HDD 10 and supply power to the CPU 8, the fan 11, and the tuner 12 based on the control signal input from the control unit 1. By setting the CPU 8, HDD 10, fan 11, and tuner 12 in a state in which power is supplied in advance from the power supply unit 7, each functional component can be put into a usable state. Compared with the case of starting up, the time required for starting can be shortened.

  The operation unit 2 includes a power-on button for power-on operation, a power-off button for power-off operation, a setting button for a program to be recorded, a recording button for recording a program, a dubbing button for high-speed dubbing a recorded program, a recording Each operation button (or operation key, operation switch, etc.), such as a play button for playing the program, a playback stop button for stopping playback, a recording stop button for stopping recording, etc. A signal indicating the operation is output to the control unit 1.

  The remote control light receiving unit 3 includes an infrared light receiving element, a demodulation circuit, and the like. The remote control light receiving unit 3 receives signals transmitted from a remote control (not shown) having various operation buttons similar to the operation unit 2, and demodulates and demodulates the received signals. The subsequent signal is output to the control unit 1.

  The timer 4 has a calendar function and a clock function, measures the current date, day of the week, hour, minute and second, and outputs the time measurement result to the control unit 1.

  The control unit 1 divides the power consumption of the entire DVD recorder 100 into a plurality of states (modes), and controls the reduction of power consumption and the startup time. For example, the quick start mode and the non-quick start mode (power saving mode) can be classified by the modes “0”, “1”, and “2” to control the start-up time and power consumption.

  FIG. 2 is an explanatory diagram showing an example of the quick start mode. In mode “1” (quick start mode), power supply to the DVD 9 is stopped, power is supplied to the CPU 8, HDD 10, fan 11, and tuner 12, so that the power can be used immediately. While minimizing the startup time.

  Mode “0” (non-quick start mode, ie, power saving mode) stops power supply to the CPU 8, DVD 9, HDD 10, fan 11, and tuner 12, and minimizes power consumption of the entire DVD recorder 100. In this case, for example, the CPU 8 may be set in a power saving mode in which the operation speed is reduced to supply power. Further, the rotational speed of the fan 11 may be reduced.

  In mode “2” (quick start mode), the power supply to the DVD 9 and the HDD 10 is stopped, the power is supplied to the CPU 8, the fan 11, and the tuner 12, and the power is immediately consumed. While suppressing, the start-up time is shortened and the balance between the two is improved. In this case, the rotational speed of the fan 11 may be reduced.

  The control unit 1 initializes all the time zones for 24 hours a day in a power saving mode (non-quick start mode) in advance. When the control unit 1 receives a power-on operation from the operation unit 2 or the remote control light receiving unit 3, the control unit 1 acquires the time when the power-on operation is received from the timer 4. The control unit 1 sets a time zone of 30 minutes before and after the acquired time to the quick start mode.

  FIG. 3 is an explanatory diagram showing a setting example of the quick start mode. In the figure, the horizontal axis indicates the time zone for one day from 0 to 24:00. As shown in FIG. 3 (a), in the initial state, all the time periods of 24 hours a day are set to the non-quick start mode, that is, the power saving mode.

  For example, when the user turns on the power at 18:00, the control unit 1 sets the time zone from 17:30 to 18:30 in the quick start mode (FIG. 3B). Thus, the DVD recorder 100 shifts to the quick start mode at 17:30 every day, and shifts to the power saving mode at 18:30.

  For example, when the user turns on the power at 19:30, the control unit 1 sets the time zone from 19:00 to 20:00 to the quick start mode (FIG. 3C). . As a result, the DVD recorder 100 shifts to the quick start mode at 17:30 every day, shifts to the power saving mode at 18:30, and starts again at 19 o'clock. The mode shifts to the power saving mode again at 20:00.

  For example, when the user turns on the power at 20:30, the control unit 1 sets the time zone from 20:00 to 21:00 to the quick start mode (FIG. 3D). . As a result, the DVD recorder 100 shifts to the quick start mode at 17:30 every day, shifts to the power saving mode at 18:30, and starts again at 19 o'clock. The mode shifts to the power saving mode again at 21:00. In the same way, the quick start mode is set in the same way, and the quick start mode is set according to the time zone used by the user, and the power saving mode is set for the time zone not used by the user. Reduce.

  In addition to the time zone of the day, the control unit 1 divides, for example, 24 hours for each day of the week into a predetermined time zone (for example, 1 hour interval) for one month, and for each divided time zone. The reception frequency of the power-on operation instruction received from the operation unit 2 or the remote control light receiving unit 3 is counted. The control unit 1 selects and sets the quick start mode (modes “1” and “2”) according to the counted reception frequency. The control unit 1 stores a mode table in which each mode is set for each day of the week and time zone in the storage unit 6.

  FIG. 4 is an explanatory diagram showing the frequency of accepting operation instructions. In the figure, the horizontal axis indicates the time zone of one day for each day of the week from 0 to 24:00. The vertical axis represents the reception frequency indicating how many times an operation instruction (for example, a power-on operation) is received during the past one month for each time slot obtained by dividing 24 hours into 24 equal parts. For example, between midnight and 1 am on Sunday, it indicates that seven operation instructions have been accepted during the past month, and between 8 am and 9 am on Sunday, 2 This indicates that the operation instruction is received three times, and between 9 am and 10 am on Sunday, it indicates that the operation instruction is received three times during the past month.

  FIG. 5 is an explanatory diagram showing the structure of the mode table. As shown in the figure, the mode table is composed of columns such as day of the week, time zone, operation instruction reception frequency, mode, and operation instruction reception date and time. The control unit 1 selects and sets the mode of the quick start mode according to the reception frequency of the operation instruction for each day of the week and time period. For example, when the threshold value for selecting and setting is “4”, the control unit 1 sets the mode “1” for the time zone in which the reception frequency is “7” as shown in the figure. On the other hand, the control unit 1 sets the mode “2” for the time periods in which the reception frequencies are “2” and “3”.

  Further, the control unit 1 updates the reception frequency by excluding the operation instructions received one month or more ago based on the reception date and time of the operation instructions recorded in the mode table. As a result, the mode setting is performed by reflecting the latest usage status for the past month.

  Next, the power consumption control operation of the DVD recorder 100 according to the present invention will be described. FIG. 6 is a flowchart showing a mode setting processing procedure. The control unit 1 determines whether or not there is an initial setting request for the quick start mode (S11). If there is an initial setting request (YES in S11), all days of the week and time zones are initialized to initialize the mode table. Is set to “0” (S12), and the mode for all days of the week and time zones is set to “0” (non-quick start mode, ie, power saving mode) (S13). In this case, the reception date and time is also set to “0”.

  The control unit 1 determines whether or not there is a power-on operation (S14). If there is no power-on operation (NO in S14), the control unit 1 continues the process of step S14 and waits until there is a power-on operation. When there is no request for initial setting (NO in S11), the control unit 1 continues the processing from step S14. When there is a power-on operation (YES in S14), the control unit 1 acquires the current day of the week and date (S15), and sets the reception frequency of the day of the week and time zone in the mode table corresponding to the acquired day of the week and date and time. 1 "is added (S16). In this case, the control unit 1 also records the reception date and time when the power-on operation is received in the mode table.

  The control unit 1 determines whether or not the reception frequency is greater than the threshold (S17). If the reception frequency is greater than the threshold (YES in S17), the control unit 1 sets the mode “1” in the quick start mode (S18). When the reception frequency is equal to or lower than the threshold (NO in S17), the control unit 1 sets the mode “2” of the quick start mode (S19).

  The control unit 1 stores the set mode table in the storage unit 6 (S20). The control unit 1 determines whether or not there is a request to end the process (S21). If there is no request to end the process (NO in S21), the process from step S14 is continued. If there is a request to end the process (YES in S21), the control unit 1 ends the process.

  FIG. 7 is a flowchart showing a processing procedure for mode table update. The control unit 1 searches for the day of the week and the time zone in the mode table from midnight on Sunday (S31). The control unit 1 determines whether or not there is a record of the reception date / time in the searched time zone (S32), and if there is no record of the reception date / time (NO in S32), the process of step S31 is continued, and the subsequent time zones The same processing is performed for the day of the week.

  When there is a record of the reception date and time (YES in S32), the control unit 1 compares the current date and time with the reception date and time (S33). When there are a plurality of records of the reception date and time in a certain time zone (that is, when the reception frequency is 2 or more), each reception date and time is compared with the current date and time.

  The control unit 1 determines whether or not the reception date / time is one month or more before the current date / time (S34), and if it is one month or more before (YES in S34), the reception is one month or more before the reception frequency. The reception frequency is updated by subtracting the number of times (S35).

  The control unit 1 determines whether or not there is a request to end the process (S36). If there is no request to end the process (NO in S36), the process from step S31 is continued. If there is a request to end the process (YES in S36), the control unit 1 ends the process. On the other hand, when the reception date / time is not more than one month before the current date / time (NO in S34), the control unit 1 continues the processing from step S36.

  FIG. 8 is a flowchart showing a processing procedure of power supply. The control unit 1 acquires the current day of the week and date (S41), accesses the mode table, and determines the quick start mode of the time zone corresponding to the acquired day of the week and date (S42).

  When the mode is “0” (“0” in S42), the control unit 1 turns off the power for the DVD, HDD, CPU, fan, and tuner (S43).

  When the mode is “1” (“1” in S42), the control unit 1 turns off the power for the DVD and turns on the power for the HDD, CPU, fan, and tuner (S44).

  When the mode is “2” (“2” in S42), the control unit 1 turns off the power for the DVD and HDD, and turns on the power for the CPU, fan, and tuner (S45).

  The control unit 1 determines whether or not there is a request to end the process (S46). If there is no request to end the process (NO in S46), the process from step S41 is continued. When there is a request to end the process (YES in S46), the control unit 1 ends the process.

  As described above, in the case of a day of the week or a time zone in which the user is frequently used, the quick start mode is set to “1” and the HDD power is turned on in advance, for example, a recording button By operating the, the program can be recorded on the HDD instantaneously and can be recorded without missing the program scene.

  In the case of a day of the week or time of day when the user is not very frequent, the quick start mode is set to “2”, the power for DVD and HDD is turned off in advance, and the CPU, tuner, fan By turning on the power supply, etc., it is possible to reduce the power consumption while shortening the startup time of the entire DVD recorder.

  Also, for days of the week and time periods when the user is not frequently used, set the mode to “0” (non-quick start mode, power saving mode), and turn off the power to DVD, HDD, CPU, tuner, fan, etc. As a result, the power consumption of the entire DVD recorder can be suppressed.

  In the above-described embodiment, the mode is set for a predetermined time zone based on the power-on operation instruction, but the present invention is not limited to this, and based on the power-off operation instruction, It is also possible to perform mode setting for a predetermined time zone, and other operation instructions may be used.

  FIG. 9 is an explanatory view showing another setting example of the quick start mode. In the figure, the horizontal axis indicates the time zone for one day from 0 to 24:00. As shown in FIG. 9 (a), in the initial state, the time zone of all 24 hours a day is set to the non-quick start mode, that is, the power saving mode.

  For example, when the user performs an operation to turn off the power at 21:00, the control unit 1 sets the time zone from one hour before the time when the power off operation is received, that is, the time zone from 20:00 to 21:00. Is set to the quick start mode (FIG. 9B). As a result, the DVD recorder 100 shifts to the quick start mode at 20:00 every day and shifts to the power saving mode at 21:00.

  For example, when the user performs a power-off operation at 22:30, the control unit 1 sets the time zone from 21:30 to 22:30 in the quick start mode (FIG. 9 ( c)). As a result, the DVD recorder 100 shifts to the quick start mode at 20:00 every day, shifts to the power saving mode at 21:00, and shifts to the quick start mode again at 21:30. Then, when it becomes 22:30, it shifts to the power saving mode again.

  For example, when the user performs a power-off operation at 23:30, the control unit 1 sets the time zone from 22:30 to 23:30 in the quick start mode (FIG. 9 ( d)). As a result, the DVD recorder 100 shifts to the quick start mode at 20:00 every day, shifts to the power saving mode at 21:00, and shifts to the quick start mode again at 21:30. At 23:30, the mode again shifts to the power saving mode. In the same way, the quick start mode is set in the same way, and the quick start mode is set according to the time zone used by the user, and the power saving mode is set for the time zone not used by the user. To reduce.

  In the above-described embodiment, the DVD recorder has been described as an example. However, the present invention is not limited to a DVD recorder, and is not limited to a DVD recorder. A television with a built-in recording function, a personal computer with a built-in tuner, a mobile phone, a music playback device, and a notebook personal computer. The present invention can be applied to any electrical apparatus such as a computer.

  In the above-described embodiment, DVD, HDD, CPU, fan, tuner, and the like have been described as functional components that can be individually supplied with power. However, functional components are not limited to these, and the present invention is not limited thereto. Functional parts that can be individually supplied with power according to the applied electrical equipment, and have a quick start mode and a power saving mode to improve user convenience in terms of startup time and power consumption Any configuration may be used.

  In the above-described embodiment, the mode setting time zone is set in units of one hour. However, the mode setting time zone is not limited to this, and may be another time zone such as a 30-minute unit.

  In the above-described embodiment, the operation instruction that has passed one month or more has been configured to exclude and update the reception frequency. However, the present invention is not limited to this, and other periods such as two months, half a month, one week, etc. May be used.

  In the above-described embodiment, the quick start mode is set to 30 minutes before and after the reception time when the power-on operation is received. However, the present invention is not limited to this, and 15 minutes before and after the reception time, or It may be one hour before and after the reception time. Also, 15 minutes before the reception time and 45 minutes after the reception time may be 1 hour in total.

  In the above-described embodiment, the configuration is such that the quick start mode is set based on the reception time when the power-on operation is received. However, the present invention is not limited to this, and it may be 5 minutes or 10 minutes in advance. The reception time can also be set by dividing 24 hours a day at intervals and depending on which time the power-on operation is accepted is close to. Thereby, since the reception time is limited to a predetermined number, it is possible to reduce the processing effort performed in the control unit 1 without lowering the accuracy of the usage situation of the user.

  In the above-described embodiment, the operation instruction that has passed for more than one month is configured to be excluded and update the reception frequency. However, the present invention is not limited to this, and for example, the control unit 1 performs a predetermined period ( (For example, 1 week, 2 weeks, etc.) When the operation instruction is not received in the time zone recorded in the mode table (when there is no reception history for a predetermined period), the time zone is set to the non-quick start mode (power saving mode). You may make it.
