Description

  The present invention relates to a startup processing control device that controls startup processing when power is turned on to a data processing device.

  In order to reduce power consumption in various data processing devices in general use, it is effective to stop all power consumption in the device completely by turning off the main power when the device is not used. is there.

  However, the applications installed in various data devices in recent years have become more and more complex year by year, and it takes longer to start up when the main power is turned off. Turning off reduces the convenience of the user at startup.

  In order to perform the startup process at the time of turning on the power at high speed, the state in which the power is turned on in advance is set to a steady state, and when the power is turned off, the display screen is darkened so that the power is turned off. It is conceivable to set the state, but in this case, the startup process is fast, but the power consumption is not substantially different from when the power is turned on, so the power consumption cannot be reduced effectively.

  Therefore, there is a data processing apparatus described in Patent Document 1 as a means for achieving both “reduction of power consumption” and “reduction of startup time”.

  The data processing apparatus described in Patent Document 1 records the generated data while the supply of power to the signal processing circuit that performs the data generation processing continues when the power supply control unit receives an instruction to turn off the power. Stop supplying power to the drive that writes to the media.

By processing in this way, power consumption can be suppressed compared to when the power is turned on when the power is turned off, and it is possible to start up faster when the power is turned on again.

  Further, in the present embodiment, as a premise that the power mode determination process is executed, the measured value of the illuminance of the room Y measured by the illuminance sensor 80 at predetermined time intervals is sent to the measured value recording unit 35 and recorded. And In the present embodiment, the interval at which the illuminance sensor 80 measures the illuminance is 1 minute.

  The operation when the power mode determination process according to the present embodiment is executed in a state where the measurement process of the illuminance in the room Y, which is the premise of these power mode determination processes, is performed, with reference to the flowchart of FIG. I will explain.

  This power mode determination process is a process executed at predetermined time intervals after the power-off instruction is acquired by the user's operation in the broadcast content recording / playback apparatus 2 until the next power-on instruction is acquired. First, when the power mode determination process is started, the time information acquisition unit 34 acquires the current time information at predetermined time intervals (S21).

  The current time information acquired by the time information acquisition unit 34 is sent to the power mode determination unit 312, and the power mode determination unit 312 corresponds to the preset daytime time zone or the night time zone. It is determined whether it is applicable (S22).

  The preset daytime and nighttime periods are classified according to time information depending on whether or not there is a natural light brightness to the extent that it is not necessary to turn on the lighting in the room Y, and are fixed time information. You may divide and may change with seasons. As an example in the case of sorting by fixed time information, there is a setting in which the daytime zone is from 7:00 am to 5:00 pm, and the night time zone is from 5:00 pm to 7:00 am.

  When it is determined in step S22 that the current time information corresponds to the daytime zone ("YES" in S22), the acquired current time information is set to the first time zone by the power mode determination unit 312 as in the first embodiment. Broadcast content recording / playback apparatus 2 is determined to be in the high-speed activation mode, and when the current time information corresponds to the second time zone, broadcast content recording / playback apparatus 2 is determined to be in the power saving mode (S23, S24, S25). ).

  When it is determined in step S22 that the current time information corresponds to the night time zone ("NO" in S22), the power mode determination unit 312 acquires the latest three measurement values from the measurement value recording unit 35. Based on the three measurement values, it is determined whether the illumination in the room Y is turned on or off (S26). In this embodiment, since the illuminance is measured at intervals of 1 minute, three measurement values of 2 minutes before, 1 minute before, and the current time are acquired.

  The operation of determining whether the illumination in the room Y is turned on or off by the power mode determination unit 312 will be described with reference to the flowchart of FIG.

  First, it is determined whether or not the illuminance two minutes before the current time is lower than the illuminance A that is an illuminance that does not require lighting of the room Y with natural light (S31).

  When it is determined in step S31 that the illuminance 2 minutes before the current time is lower than the illuminance A ("YES" in S31: the room Y needs illumination but is not lit), the current time is 1 minute further It is determined whether the illuminance is lower than the illuminance A (S32).

  When it is determined in step S32 that the illuminance one minute before the current time is also lower than the illuminance A ("YES" in S32: the room Y needs illumination but is not lit), the illuminance at the current time is further increased. Then, it is recognized that the illumination in the room Y is turned on, and it is determined whether or not the illumination intensity B is higher than the illumination intensity A (S33).
