Description

  The present invention relates to a radio-controlled timepiece that receives a standard radio wave including a standard time information signal and corrects a display time based on the extracted standard time information signal.

  A radio-controlled timepiece that has a function to receive a standard radio wave including a standard time information signal and correct the display time based on the extracted standard time information signal is received at a preset normal reception time (periodic reception time). The display time correction process is automatically executed based on the standard time information signal extracted from the standard radio wave. Recently, there is also a radio-controlled timepiece that allows the display time correction process to be executed from a preset normal reception time to an arbitrary reception time (arbitrary reception time) arbitrarily set by the operator (user). It has been proposed (see, for example, Patent Document 1).

In the radio-controlled timepiece as described in Patent Document 1, when the normal reception time is set in advance, for example, 2:00 am, 3:00 pm, 4 pm every day, the operator can set the optional reception time as, for example, 6:00 pm every day, When set by operating the operation buttons at 7 o'clock and 8 o'clock, the standard radio wave reception operation is executed every day at 6 o'clock, 7 o'clock, and 8 o'clock, which is an arbitrary reception time. The reason for setting multiple reception times (time) as normal reception time and arbitrary reception time is to receive again when reception fails due to radio wave reception status, etc., and reception was successful at the first reception time. In this case, the standard radio wave reception operation is not performed at the subsequent reception time.
JP 2006-119209 A

  As described above, when the arbitrary reception time is set by the operation of the operator, all of the preset normal reception times are changed to the set arbitrary reception time. In addition, the normal reception time is set in advance from midnight to early morning (for example, every two hours at 2:00, 3:00, and 4:00), which are generally less affected by noise and noise radio waves than in the daytime.

  For this reason, when the arbitrary reception time is changed by a user's operation to a time other than midnight to an early morning time (for example, every hour from 6 pm, 7 pm, or 8 pm), for example, when traveling to North America If the day is the start date of daylight saving time (daylight saving time in the case of North America, it is 2:00 am on the first Sunday in April), if it is set to the normal reception time, When radio wave reception fails, correction is automatically performed so that the time is advanced by 1 hour at 3 am or 4 am, but as described above, any reception time (for example, 6 pm, 7 pm, 8 pm) If the time is changed and set, the display time correction process is not performed until this arbitrary reception time, and the time corresponding to the daylight saving time may not be displayed for a long time.

  In view of the above, the present invention has an object to provide a radio-controlled timepiece capable of performing a display time correction process based on both a normal reception time set in advance and an arbitrary reception time set by an operator. And

  The invention according to claim 2 excludes at least one reception time among the plurality of reception times when the normal reception time storage means stores a plurality of reception times as the normal reception time. The other reception time can be set by changing to an arbitrary reception time by an operator's operation, and the setting control means uses the changed reception time as the arbitrary reception time. It is characterized by memorizing.

  The invention according to claim 3 is characterized in that it has display means capable of displaying the changed reception time stored in the arbitrary reception time storage means.

  According to a fourth aspect of the present invention, the arbitrary reception time storage means can store a plurality of reception times as the arbitrary reception time, and the setting control means is stored in the normal reception time storage means. Other reception times other than the normal reception time and the arbitrary reception time previously stored in the arbitrary reception time storage unit are stored in the arbitrary reception time storage unit.

  The invention according to claim 5 is characterized in that it has display means capable of switching and displaying the other reception times stored in the arbitrary reception time storage means in order.

  The invention described in claim 6 is characterized in that it has a display means capable of simultaneously displaying the other reception times stored in the arbitrary reception time storage means.

  The invention according to claim 7 includes an automatic reception mode in which a reception operation is performed only at the normal reception time, and a composite reception mode in which a reception operation is performed at both the normal reception time and the arbitrary reception time. And the arbitrary reception time is displayed on the display means only in the composite reception mode.

  According to the radio-controlled timepiece according to the present invention, it is possible to perform display time correction processing based on both the normal reception time set in advance and the arbitrary reception time set by the operator, and arbitrary reception Since it is possible to prevent the timing from overlapping with a preset normal reception timing, it is possible to prevent the number of times of reception of the standard radio wave by the radio wave receiving means from being reduced.

  The radio wave reception unit 2 includes a reception unit 11 that receives a standard radio wave via the antenna 10 and a signal analysis unit that extracts a time data signal (standard time information signal) b from a reception signal (standard radio wave) a received by the reception unit 11. 12 and a reception information storage unit 13 for recording the time data signal b obtained by the signal analysis unit 12 as reception time information. In the present embodiment, the radio wave receiving unit 2 receives standard radio waves (time data) in Japan, North America (USA), or Europe (Germany) by operating a user's operation button (not shown). It is configured to be able to select and receive.

  The reception operation setting control unit 3 operates the radio wave reception unit 2 to cause the radio wave reception unit 2 to receive a standard radio wave when a normal reception time set in advance and an arbitrary reception time set by a user's manual operation are reached. The time correction operation is executed (details will be described later).

  The hand movement control unit 4 includes an oscillation unit 14, a frequency division unit 15, an internal clock counter 16, a drive control unit 17, an hour / minute hand drive unit 18, a second hand drive unit 19, a comparison unit 20, and a time correction control unit 21. .

  The oscillating unit 14 oscillates the crystal resonator at a high frequency, and the frequency dividing unit 15 divides the oscillation signal c and outputs a predetermined reference signal d to the internal clock counter 16. The internal clock counter 16 counts the reference signal d and outputs an internal time signal (reference time signal) e to the drive control unit 17. The drive control unit 17 outputs an hour / minute hand drive control signal f to the hour / minute hand drive unit 18 and a second hand drive control signal g to the second hand drive unit 19 based on the input internal time signal (reference time signal) e. Output.

  The hour / minute hand drive unit 18 outputs a drive pulse signal h to a step motor (not shown) that drives the hour hand 5 and the minute hand 6 based on the input hour / minute hand drive control signal f, and the second hand drive unit 19 receives the input. By outputting a drive pulse signal i to a step motor (not shown) for driving the second hand 7 based on the second hand drive control signal g, the hour hand 5, the minute hand 6, and the second hand 7 are internally time signals (reference time signals). The current time according to e is indicated. The hour hand 5 and the minute hand 6 are driven via a plurality of gear trains by one step motor, and the second hand 7 is driven via a plurality of gear trains by another step motor.

  The comparison unit 20 receives a reception information signal (time data signal b) j input from the reception information storage unit 13 of the radio wave reception unit 2 and the internal clock counter 16 when the radio wave reception unit 2 receives the standard radio wave. When the time (pointer time) indicated by the hands (hour hand 5, minute hand 6, second hand 7) is different from the received time (standard time) by comparing with the internal time signal e, the time according to the time difference The difference signal k is output to the time correction control unit 21. The time adjustment control unit 21 outputs the time adjustment signal 1 to the internal clock counter 16 based on the input time difference signal k, and increases or decreases the count value in the internal clock counter 16, and the internal time is received. Correct to match the time (standard time).

  The reception operation setting control unit 3 includes a normal reception timing storage unit 22, an arbitrary reception timing setting control unit 23, an arbitrary reception timing storage unit 24, a reception operation control unit 25, and a display unit 26.

  The normal reception time storage unit 22 stores a normal reception time (periodic reception time) set in advance when the radio-controlled timepiece 1 is manufactured as a standard radio wave reception time by the radio wave reception unit 2. As the normal reception time set in advance, in this embodiment, taking into account the case where the reception could not be performed once due to the reception situation, three reception times every hour at 2 am, 3 am and 4 am Is set. In the present embodiment, the third reception time (4 am) of the three reception times is set to any value by the setting control of the arbitrary reception time setting control unit 23 by operating the first operation button 27. It is configured so that it can be changed at any reception time. The reason for setting the normal reception time at 2:00, 3:00, and 4:00 is that the time from midnight to early morning when the reception of radio waves is less affected by noise and noise than the daytime is more advantageous.

  The arbitrary reception time setting control unit 23 sets an arbitrary reception time (for example, 12:00 am (midnight)) set by the user by operating the first operation button 27 by the user, and this setting is performed. The arbitrary reception time is stored in the arbitrary reception time storage unit 24. Further, the arbitrary reception time set in the arbitrary reception time setting control unit 23 is configured to be displayed on the display unit 26 including a liquid crystal display panel provided in the dial unit 8.

When the reception time comes, a reception operation signal m is output to the radio wave receiver 2. The radio wave receiver 2 starts an operation of receiving a standard radio wave based on the input reception operation signal m.

  In the present embodiment, when the user operates the second operation button 28, the reception operation signal m is received from the reception operation control unit 25 even when the normal reception time and the arbitrary reception time are reached. So that the reception operation can be stopped (OFF). Further, when the user operates a third operation button (not shown), a forced reception signal is output from the reception operation control unit 25 to the radio wave reception unit 2, and a standard radio wave reception operation can be started. The first operation button 27 and the second operation button 28 are provided in the vicinity of both sides of the crown 29 provided on the side surface of the dial portion 8.

Next, the operation of the radio-controlled timepiece 1 when the above-described reception operation setting control unit 3 sets only the normal reception time and the arbitrary reception time will be described.
[When only normal reception time is set]

  As shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C, three modes are set as reception operation modes of the radio-controlled timepiece 1. Each will be briefly described as follows. 2A, 2B, and 2C show display states on the display unit 26 when each mode is set.

  “AUT” in FIG. 2A indicates an automatic reception mode in which reception is performed only during normal reception timing. In this automatic reception mode, the arbitrary reception time cannot be set and is not displayed.

  “MAN” in FIG. 2B indicates a composite reception mode in which reception is possible at both the normal reception time and the arbitrary reception time. Since the arbitrary reception time can be set in the composite reception mode, the currently set arbitrary reception time is displayed.

  “OFF” in FIG. 2C indicates a mode in which reception is completely prohibited. In this mode, of course, the arbitrary reception time cannot be set and is not displayed.

  Each of these three modes can be arbitrarily selected by the user (for example, it can be switched by operating the second operation button 28).

  As described above, the radio-controlled timepiece 1 according to the present embodiment receives the reception operation control unit at the normal reception time (in the present embodiment, every day at 2 am, 3 am, and 4 am) set in advance during normal time. 25 outputs a reception operation signal m to the radio wave reception unit 2 based on the signal n from the normal reception time storage unit 22 and the internal time signal e input from the internal clock counter 16. At this time, for example, the characters “AUT” (auto) corresponding to the state of the normal reception time are displayed on the display unit 26 as shown in FIG. At this time, the first operation button 27 and the second operation button 28 are not operated.

  Then, the radio wave receiving unit 2 starts the operation of receiving the standard radio wave based on the input reception operation signal m at 2:00 am of the first normal reception time.

  The radio wave receiver 2 receives the standard radio wave via the antenna 10 at the receiver 11, and the signal analyzer 12 extracts the time data signal b from the received signal (standard radio wave) a received at the receiver 11, and this time The data signal b is recorded in the reception information storage unit 13 as reception time information.

  If the radio wave reception unit 2 successfully receives the standard radio wave at 2:00 am in the first normal reception period, the radio wave reception unit 2 does not receive the standard radio wave after the second normal reception period. In addition, when the standard radio wave reception fails at 2:00 am in the first normal reception time, the standard radio wave is received again at 3:00 am in the second normal reception time. If the reception of the standard radio wave fails at 2 am, the standard radio wave is received again at 4 am, the third reception time of the normal reception period. If reception of the standard radio wave fails even at the third reception time of 4 am, stop receiving the standard radio wave, stop the time adjustment operation, and start receiving the standard radio wave again from 2 am the next day. Do.

  When the standard radio wave is successfully received at the first reception time of 2:00 am, the comparison unit 20 of the hand movement control unit 4 receives the reception time information signal (time) input from the reception information storage unit 13 of the radio wave reception unit 2. The data signal b) j is compared with the internal time signal e input from the internal clock counter 16, and the time (standard time) indicated by the hands (hour hand 5, minute hand 6, second hand 7) is received (standard time) If it is different from (time), a time difference signal k corresponding to the time difference is output to the time correction control unit 21. The time adjustment control unit 21 outputs the time adjustment signal 1 to the internal clock counter 16 based on the input time difference signal k, and increases or decreases the count value in the internal clock counter 16, and the internal time is received. Correct to match the time (standard time).

  It should be noted that the time from the reception of the standard radio wave to the comparison processing of the reception time information signal (time data signal b) j and the internal time signal e by the comparison unit 20 is usually about several minutes to 15 minutes. In order to reduce the generation of internal noise, the second hand 7 is held at a predetermined position in a stopped state, and the hour hand 5 and the minute hand 6 are driven each time one minute elapses.

  As described above, when the time (point time) indicated by the hands (hour hand 5, minute hand 6, second hand 7) is different from the received time (standard time), the internal clock counter 16 sets the time correction control unit 21. The internal time signal is corrected after the internal time is corrected to coincide with the received time (standard time) by increasing or decreasing the count value in the internal clock counter 16 based on the time correction signal l output from e is output to the drive control unit 17.

  The drive control unit 17 outputs an hour / minute hand drive control signal f to the hour / minute hand drive unit 18 and outputs a second hand drive control signal g to the second hand drive unit 19 based on the corrected internal time signal e inputted. . The hour / minute hand drive unit 18 outputs a drive pulse signal h to a step motor (not shown) that drives the hour hand 5 and the minute hand 6 based on the input hour / minute hand drive control signal f, and the second hand drive unit 19 receives the input. On the basis of the second hand drive control signal g, an internal time signal (reference time) corrected by the hour hand 5, the minute hand 6, and the second hand 7 by outputting a drive pulse signal i to a step motor (not shown) for driving the second hand 7 The hand is driven to indicate the current time according to the signal e).

  The comparison unit 20 compares the reception time information signal (time data signal b) j output from the reception information storage unit 13 of the radio wave reception unit 2 with the internal time signal e output from the internal clock counter 16. When the time (pointer time) indicated by the hands (hour hand 5, minute hand 6, second hand 7) coincides with the received time (standard time), the time indicated by the hands (hour hand 5, minute hand 6, second hand 7) Since there is no deviation, the time adjustment operation is canceled.

[When the optional reception time is set in addition to the normal reception time setting]
As described above, the radio-controlled timepiece 1 according to the present embodiment changes the third reception time (4 am) to the arbitrary reception time set by the user by operating the first operation button 27. can do.

  That is, when the user operates the first operation button 27, the arbitrary reception time setting control unit 23 is in a state where the arbitrary reception time can be set. Setting control by the arbitrary reception timing setting control unit 23 will be described with reference to a flowchart shown in FIG.

  First, when the user operates the first operation button 27, the arbitrary reception time setting control unit 23 sets an arbitrary arbitrary reception time selected by the user, and the set arbitrary reception time is the normal reception time storage unit. Based on the signal (normal reception time information) o output from the terminal 22, it is determined whether or not it matches the preset normal reception time (step S1).

  If the set arbitrary reception time overlaps (matches) with the normal reception time in step S1 (step S1: YES), a warning is given that the arbitrary reception time set on the display unit 26 overlaps with the normal reception time. Such display is performed on the display unit 26 (step S2), and the user is warned. As a warning display in this case, for example, a process of applying a mesh on the display surface of the selected arbitrary reception time is performed. In addition to the means for meshing on the display surface, the warning means may be, for example, displaying characters that prompt the user to set the reception time again, or issuing a warning with a sound emitted from a buzzer or the like. A combination of these may also be used.

  On the other hand, if the set arbitrary reception time does not overlap with the normal reception time in step S1 (step S1: NO), the signal p is output to the arbitrary reception time storage unit 24 to store the arbitrary reception time ( Step S3). At this time, on the display unit 26, based on the signal q output from the arbitrary reception timing setting control unit 23, for example, as shown in FIG. 2B, “MAN” ( Manual), “12:00” which is the time of the set arbitrary reception time, and “A” (AM) indicating AM.

  The reception operation control unit 25 then converts the signal n output from the normal reception timing storage unit 22 and the signal r output from the arbitrary reception timing storage unit 24 into an internal time signal e input from the internal clock counter 16. Based on whether or not they match, a reception operation signal m is output to the radio wave receiver 2. That is, the radio wave receiving unit 2 uses the normal reception time (in this embodiment, 2 am and 3 am every day) for receiving the standard radio wave the first time and the second time based on the input reception operation signal m. The time for receiving the standard radio wave for the third time is an arbitrary reception time set by the user (in this embodiment, 12:00 am every day).

  As described above, when there are a plurality of normal reception times for operating the radio wave receiver 2, one of the reception times can be easily changed to an arbitrary reception time set by the user.

  Therefore, even when the user has set an arbitrary reception time as described above, for example, when traveling to North America, the day is the start date of daylight saving time (daylight saving time) (in the case of North America, the first Sunday in April) In the case of 2 am), it is possible to automatically execute correction such that the time is advanced by 1 hour at a preset normal reception time (2 am, 3 am).

  In addition, when the user operates the second operation button 28, the reception operation control unit 25 does not output the reception operation signal m to the radio wave reception unit 2 even when the normal reception time and the arbitrary reception time are reached. The reception operation is stopped (OFF). At this time, for example, as shown in FIG. 2C, the character “OFF” corresponding to the stop state of the reception operation is displayed on the display unit 26.

  In the first embodiment, the user is allowed to select an arbitrary reception time. However, the present invention is not limited to this. For example, a plurality of recommended reception times are displayed and selected with an operation button. You may be able to do it. In addition, the reception time desired by the user may be input in units of hours and minutes, or the reception time may be increased or decreased by a predetermined time width.

<Embodiment 2>
In the present embodiment, when the user operates the first operation button 27, the arbitrary reception time setting control unit 23 sets a plurality of arbitrary arbitrary reception times selected by the user. At this time, the arbitrary reception timing setting control unit 23 selects the normal reception timing stored in the normal reception timing storage unit 22 and the previous (in the arbitrary reception timing storage unit 24) for the selected arbitrary arbitrary reception timings. Other reception times other than the arbitrary reception time stored in (1) are stored in the arbitrary reception time storage unit 24.

  Further, in the present embodiment, the time of arbitrary reception time can be set at intervals of 15 minutes. The configuration of the radio-controlled timepiece according to this embodiment is the same as that of the radio-controlled timepiece according to Embodiment 1 shown in FIG.

  The plurality of arbitrary reception times stored in the arbitrary reception time storage unit 24 are displayed on the display unit 26, for example, as shown in FIG. In FIG. 4, “MAN” (manual) characters corresponding to the state of the arbitrary reception time, and “5:00” and “23:45”, which are the set arbitrary reception times, are displayed. In addition, when there are two or more arbitrary reception times stored in the arbitrary reception time storage unit 24, the next reception time can be switched in order and displayed.

  Next, the arbitrary reception timing setting control in the present embodiment will be described with reference to the flowchart shown in FIG.

  First, when the user operates the first operation button 27 (see FIG. 1), the arbitrary reception time setting control unit 23 sets a plurality of arbitrary arbitrary reception times selected by the user, and this selected arbitrary reception time. However, based on the signal (normal reception time information) o output from the normal reception time storage unit 22, it is determined whether or not it matches the preset normal reception time (step S11).

  In step S11, if the set arbitrary reception time overlaps (matches) with the normal reception time (step S11: YES), the display unit 26 warns that the arbitrary reception time overlaps with the normal reception time. Such display is performed on the display unit 26 (step S12), and the user is warned. As a warning display in this case, for example, a process of applying a mesh on the display surface of the selected arbitrary reception time is performed.

  On the other hand, if the set arbitrary reception time does not overlap (does not match) with the normal reception time in step S11 (step S11: NO), the process proceeds to step S13. In step S13, if the set arbitrary reception time overlaps with the arbitrary reception time previously stored in the arbitrary reception time storage unit 24 (step S13: YES), the arbitrary reception selected on the display unit 26 is displayed. A display that warns that the time overlaps with the normal reception time is displayed on the display unit 26 (step S12), and the user is warned. As a warning display in this case, for example, a process of applying a mesh on the display surface of the selected arbitrary reception time is performed.

  Further, in step S13, if the set arbitrary reception time does not overlap with (or does not match) the arbitrary reception time previously stored (step S13: NO), the arbitrary reception time storage unit The signal p is output to 24 and the set arbitrary reception time is stored (step S14). At this time, based on the signal q output from the arbitrary reception time setting control unit 23, the display unit 26, for example, The two arbitrary reception times as shown in FIG. 4 are displayed.

  As described above, in the present embodiment, even when there are two or more arbitrary reception times stored in the arbitrary reception time storage unit 24, the next reception time can be switched in order and displayed. On the other hand, it is possible to visually confirm the arbitrary reception time set for the user.

  In the second embodiment, since the time of arbitrary reception timing can be set at intervals of 15 minutes, for example, when the maximum reception time required for one reception operation is 15 minutes, the previous (first) The reception operation is executed when the next arbitrary reception time comes after the reception operation at the arbitrary reception time stored in (1) ends. Therefore, during the reception operation at the arbitrary reception time stored before (previous), when another arbitrary reception time set later comes, the reception operation at the arbitrary reception time set later is ignored. The reception operation can be executed for the set number of times.

  In this way, by considering the maximum reception operation time required for one reception operation, the arbitrary reception time set later is set to the arbitrary reception time or the normal reception time stored before (first). It may be set and controlled so as not to overlap with the reception time in consideration of the maximum reception operation time.

<Embodiment 3>
In the second embodiment, when there are two or more arbitrary reception times stored in the arbitrary reception time storage unit 24, the next reception time is switched in order and displayed. However, in this embodiment, any arbitrary reception time is displayed. Even when there are two or more arbitrary reception times stored in the reception time storage unit 24, for example, as shown in FIG. 6, a plurality of arbitrary reception times can be displayed on the display unit 26 at the same time. Yes.

  In FIG. 6, “MANUAL SETTING” (manual setting) corresponding to the state of the arbitrary reception time, the set arbitrary reception time “2006/12/23 SAT 5:00”, and “2006/12/30 SAT” "4:30" and "SUN 1:30" are displayed at the same time.

  As described above, in the present embodiment, even when there are two or more arbitrary reception times stored in the arbitrary reception time storage unit 24, they can all be displayed at the same time, so that the arbitrary reception set for the user can be displayed. The time can be easily confirmed visually.
