International Publication No. 97/21533 pamphlet (pages 25-27)

  The information storage means at the time of power supply power reduction in the conventional electronic clock circuit system stores the alarm time using a non-volatile memory as a data memory, and is obtained from the outside when the power supply voltage is restored by battery replacement or the like A means for outputting an alarm signal when the time coincides with the alarm time is used.

  However, this system has a problem that when the power supply is restored, the information processing means used before the power supply voltage drops cannot be continued as it is.

  That is, as in Patent Document 1, a technique capable of storing a temporary point such as an alarm time has been proposed, but predetermined information that is continuously operated when the power supply voltage decreases, for example, stop When the watch is in operation, the timing information is erased. Therefore, even if the power supply voltage is restored by replacing the battery, the timing information cannot take over the previous state.

  Therefore, it is difficult to continue the function from the starting point of the information processing means that was operating before the power supply voltage is lowered.

  Therefore, an object of the present invention is to compare the information acquired from the nonvolatile memory with the current time acquired from the outside when the power supply voltage is restored, and to determine the starting point of the information processing means that was operating before the power supply voltage decreased. The operation of the information processing means can be continued as a base point.

The solution of the present invention to achieve the above object is as follows.
Time measuring means for measuring time information, an information display unit for displaying time information output from the time measuring means, a non-volatile memory for storing predetermined information, and predetermined time based on the time information of the time measuring means Information processing means for outputting notification information at time, a time information acquisition circuit for acquiring time information from the outside, time information stored in the nonvolatile memory, and time information acquired from the outside by the time information acquisition circuit Comparing means for comparing and determining whether it is time to notify the notification information, a power supply unit for supplying power to each circuit, and a power supply capability value representing the power supply capability of the power supply unit operate each circuit. When it is determined by the power supply state detection circuit that determines whether or not the predetermined value for enabling has been exceeded, and the power supply state detection circuit that the power supply capability value of the power supply unit does not exceed the predetermined value, The operation of the time means and the information processing means is stopped, and the time information and the notification information are transferred to the nonvolatile memory and stored, and then the power supply capacity value of the power supply unit exceeds a predetermined value. When the determination is made, the notification information stored in the nonvolatile memory is transferred to the information processing means, the time information income circuit is operated to acquire time information from the outside, and the acquired time information and the nonvolatile memory are An electronic device comprising: control means for controlling the output of the notification information from the information processing means by comparing the time information stored in the information processing means with the comparing means.

  Further, the control means operates the time information income circuit to acquire time information from the outside, and as a result of comparing the acquired time information and the time information stored in the nonvolatile memory by the comparison means, If it is determined that output of the notification information from the information processing means should be permitted, control is performed so that the notification information from the information processing means is immediately output.

  Further, the control means operates the time information income circuit to acquire time information from the outside, and as a result of comparing the acquired time information and the time information stored in the nonvolatile memory by the comparison means, If it is not the time at which the output of the notification information from the information processing means should be permitted, but it is necessary to permit the output after a predetermined time, the time information and the notification information stored in the nonvolatile memory are stored in the information processing. Control to transfer to the means.

  Further, the control means operates the time information income circuit to acquire time information from the outside, and as a result of comparing the acquired time information and the time information stored in the nonvolatile memory by the comparison means, If it is determined that it is no longer necessary to permit the output of the notification information from the information processing means, the time information and the notification information stored in the nonvolatile memory are controlled to be deleted.

  In addition, the information processing means stores an end time when the diving activity is ended, and outputs a flying board prohibition information as the notification information for a predetermined time from the end time based on the time information of the time measuring means. The non-volatile memory stores the end time and the flight prohibition information stored by the diving information processing means.

  In addition, the information processing means stores the medication time, and when the arrival of the medication time is detected based on the time information of the time measuring means, the medication time information processing that outputs medication arousal information prompting medication as the notification information The non-volatile memory stores the medication time and medication awakening information stored by the medication time information processing means.

  Since the present invention employs the above-described configuration, the state before the power supply voltage is lowered is continued by the power supply voltage being restored regardless of the functional state that was operating before the power supply voltage was lowered. The effect that it can be easily obtained is exhibited. As a particularly remarkable effect, the power supply voltage drops while warning of prohibition of boarding after the diver watch diving is finished, and then the power supply voltage is restored, and the information stored in the nonvolatile memory and the external The obtained time information is compared, and the display of the aircraft boarding prohibition warning can be restored starting from the start point of the information processing means that was operating before the power supply voltage decreased.

(First operation)
Next, the first operation of the present embodiment will be described with reference to FIGS. The first operation of the present embodiment is to display a warning during an airplane boarding prohibition period that starts after the diving activity ends. During the warning display, the voltage of the storage battery 4 of the watch exceeds a predetermined threshold value. The case where the warning display is turned off after the airplane boarding prohibition period has elapsed will be described.

  5, (A) represents the start time T1, the end time T2, and the airplane boarding prohibition time T8 of the diving activity, (B) represents the state of the display unit 6, and (C) represents the calculation function of the microcomputer 2. An operation state is represented, and (D) represents a voltage of the power storage unit 4.

  In FIG. 5, the time before the time T1 is a normal timepiece use state on land, so the display unit 6 displays the time. The voltage of the power storage unit 4 is higher than a predetermined voltage threshold.

  Next, when it is determined that the diving activity is started from time T1 based on the water depth information obtained from the sensor unit 14, the display unit 6 displays a diving display necessary for the diving activity. At this time, the microcomputer 2 executes START in FIG. 3, and determines whether the diving activity is finished in step S1.

  Next, based on the water depth information obtained from the sensor unit 14, if it is determined that the diving activity has ended at time T2, the calculation function of the microcomputer 2 operates, and in step S1, it is determined that the diving activity has ended. Then, the process proceeds to step S2. In step S <b> 2, the microcomputer 2 outputs a signal to the display circuit 5 so as to light the warning display mark 17 indicating that airplane boarding is prohibited, and executes a warning display on the liquid crystal display unit 15 of the display unit 6.

  Then, the processing of the microcomputer 2 proceeds to step S3, and the time T2 is set as the start time for prohibiting airplane boarding, and measurement of the passage of time from that point is started.

Then, in step S4, it is determined whether or not the elapsed time from the measurement start time has reached a predetermined time T8. If the voltage of the storage battery 4 does not decrease and the time T8 is exceeded as it is, the process proceeds to step S5, the warning display mark 17 is turned off and END is set.
(Second operation)
Next, the second operation of this embodiment will be described with reference to FIGS. 3, 4, 5, 7, and 8. FIG. The second operation of the present embodiment is to display a warning during an airplane boarding prohibition period that starts after the diving activity ends, and the voltage of the storage battery 4 of the watch is lower than a predetermined threshold value during the warning display. A description will be given of a case where the warning display once disappears due to a drop, but the power supply of the clock is restored during the airplane boarding prohibition period and the warning display is continuously displayed.

  Until time T2, the operation is the same as described above, and thus the description thereof is omitted. When the voltage of the power storage unit 4 becomes lower than a predetermined threshold at time T3, the power supply state detection circuit 3 detects a voltage drop and outputs a detection signal to the microcomputer 2. The microcomputer 2 executes processing from START in FIG. 4 based on the detection signal detected by the power supply state detection circuit 3. In step SS1, the microcomputer 2 detects the detection signal from the power supply state detection circuit 3 that is output when the voltage of the power storage unit 4 is lower than the predetermined threshold value. Execute the process of transferring information to

Next, information transferred to the nonvolatile memory in step SS2 will be described with reference to FIG. In the microcomputer 2, the time measuring means includes information on the current time information such as year, month, day, hour, minute, and second. A plurality of functions can be set in the information processing means, and a flag indicating whether or not each function is operating is set. Among the functions, there is an airplane boarding prohibition function, and the measurement start time information is stored for the airplane boarding prohibition function. At present, since only the airplane boarding prohibition function is operating, the flag there is 1, and the flags for other functions are 0. In the present embodiment, when the power supply state detection circuit 3 detects that the voltage of the power storage unit 4 is lower than a predetermined threshold value, the control means in the microcomputer 2 displays the information in the time measuring means and the information in the information processing means. Transfer to the non-volatile memory 7.

  After each information is transferred to the nonvolatile memory 7 and the stop flag is set to 1 (not shown), the processing of the microcomputer 2 proceeds to step SS3 at time T4. Then, the power supply from the power storage unit 4 to each circuit is stopped, and END is set.

  Next, when the voltage of the power storage unit 4 returns to a predetermined threshold value or more due to charging by the solar battery 9 at time T <b> 5, the power supply state detection circuit 3 detects the voltage return and outputs a detection signal to the microcomputer 2. The microcomputer 2 restarts the power supply from the power storage unit 4 to each circuit based on the detection signal detected by the power supply state detection circuit 3, and executes the process again from START in FIG.

  The processing of the microcomputer 2 proceeds to step SS1. At this time, since the voltage of the power storage unit 4 is equal to or higher than a predetermined threshold value, the process proceeds to step SS4. In step SS4, the return of the power storage unit (power supply voltage) 4 is detected. Although not shown, when the stop flag of the nonvolatile memory 7 is set to 1, it is determined that the return is made, and the step is performed at the timing of time T6. Move to SS5. Thereafter, the stop flag is set to 0.

  At time T5, the microcomputer 2 outputs an operation command signal to the time information acquisition circuit 11. As a result, the time information acquisition circuit 11 operates to receive radio waves including time information obtained from the receiving antenna 12. Next, in step SS6, the microcomputer 2 acquires time information obtained by the time information acquisition circuit 11, and reads information stored in the nonvolatile memory 7 before the voltage of the power storage unit 4 is decreased in step SS7. The time measuring means in the microcomputer 2 is controlled by the time information obtained by the time information acquisition circuit 11 by the control means.

  Next, information read from the nonvolatile memory 7 in step SS7 will be described with reference to FIG. The control means in the microcomputer 2 includes the year, month, day, hour, minute, and second information as current time information from the time information acquisition circuit 11 and the time when the power supply voltage stored in the nonvolatile memory 7 is lowered. Information such as year, month, day, hour, minute, and second is transferred to the comparison means.

  Further, the control means in the microcomputer 2 transfers the information stored in the nonvolatile memory 7 to the information processing means as it is when the power is lowered. Specifically, measurement start time information is transferred for operation flags of a plurality of functions and airplane boarding prohibition functions. The flag is 1 because only the airplane boarding prohibition function is operating as a state before the power supply voltage is lowered, and the flag is 0 because the other functions are not operating.

  Next, in step SS8, the microcomputer 2 determines that the information processing means is measuring the airplane boarding prohibition time before the power supply voltage is reduced based on the operation flag of each function acquired from the nonvolatile memory 7, and in step SS9, The current time information acquired by the time information acquisition circuit 11 is compared with the time information of the nonvolatile memory 7 which is the time information when the power supply voltage decreases, and the voltage of the power storage unit 4 decreases, and the diver clock The elapsed time that was not operating is calculated.

  Next, at time T7, the processing of the microcomputer 2 proceeds to step SS10. In step SS10, the elapsed time from the measurement start time T2 is calculated based on the measurement start time T2 of the airplane boarding prohibition time, and the elapsed time obtained by the comparison means that the diver's clock has not been operated is added. It is determined whether or not the time T8 that is the end time of the prohibited time has passed.

  At this time, if the time T8 has not passed, in step SS11, notification information is output from the information processing means of the microcomputer 2 to the display circuit 5, and the display circuit 5 displays the liquid crystal display unit of the display unit 6 based on the notification information. The warning display mark 17 is immediately turned on at 15.

Thereafter, when the time has elapsed and it is determined in step SS10 that the elapsed time from the measurement start time T2 has passed the time T8, which is the end time of the airplane boarding prohibition time, the warning display mark 17 is turned off in step SS12. Further, in the information processing means of the microcomputer 2, the airplane boarding prohibition function flag is reset to 0 and becomes END.

In the third operation of the present embodiment, a warning is displayed during an airplane boarding prohibition period that is started after the diving activity is completed, and the voltage of the storage battery 4 of the watch is lower than a predetermined threshold value during the warning display. The warning display disappears once it drops. Subsequently, a case will be described in which the clock is turned off after the airplane boarding prohibition period, and the warning display is turned off when it is determined that the elapsed time from the measurement start time T2 has passed the time T8 that is the end time of the airplane boarding prohibition time.

  The third operation in FIG. 6 is the same as the second operation in FIG. 5 from time T1 to time T4, and thus the description is omitted, and the operation from time T8 will be described. At T8, the microcomputer 2 does not operate because the voltage of the power storage unit 4 is lower than the predetermined threshold.

  Next, at time T9, the voltage of the power storage unit 4 returns to a predetermined threshold value or more. Since time T9 to time T10 are the same as time T5 to time T6 of the second operation, description thereof will be omitted, and operation from time T11 will be described.

At time T11, the processing of the microcomputer 2 proceeds to step SS10. In step SS10, the elapsed time from the measurement start time T2 is calculated based on the measurement start time T2 of the airplane boarding prohibition time, and the elapsed time obtained by the comparison means that the diver's clock has not been operated is added. It is determined whether or not the time T8 that is the end time of the prohibited time has passed. At this time, if it is determined that the elapsed time from the measurement start time T2 has passed the time T8, which is the end time of the no-flying time, the warning display mark 17 is not turned on in step SS12, and the information processing means of the microcomputer 2 Return the airplane boarding prohibition function flag to 0 and become END.

Next, an embodiment in which a medicine medication notification function is added in the user measurement processing 1 of the information processing means in the microcomputer 2 shown in FIGS. 7 and 8 will be described. The medication notification function stores the measurement start time information as in the airplane boarding prohibition function. In addition, since the operation flag of the airplane boarding prohibition function is 0, the airplane boarding prohibition function is not operating.

FIG. 9 is a first flowchart for explaining the operation of the diver watch having the medication notification function according to the present invention. FIG. 10 is a second flowchart for explaining the operation of the diver watch having the medication notification function according to the present invention. FIG. 11 is a first timing chart showing the operation of the diver watch having the medication notification function according to the present invention.

Next, the first operation of this embodiment will be described with reference to FIGS. First of this embodiment
In this operation, a warning is displayed after the next medication time has elapsed since the medication function was executed, and the elapsed time since the medication function was executed is measured. During this period, the voltage of the storage battery 4 of the watch is kept above a predetermined threshold value, and a warning display is executed after the medication time has elapsed. A case will be described in which the warning display is turned off by the user operating the input unit 8 at this time.

  In FIG. 11, (A) represents the medication function execution time and medication time, (B) represents the state of the display unit 6, (C) represents the operating state of the arithmetic function of the microcomputer 2, and (D) represents The voltage of the electrical storage part 4 is represented. In FIG. 11, the time before the time T ′ 1 is a normal timepiece use state, so the display unit 6 displays the time. The voltage of the power storage unit 4 is higher than a predetermined voltage threshold.

Next, medication is performed, and the user operates the input unit 8 to execute the medication function from time T′1. In the microcomputer 2, START in FIG. 9 is executed. The processing of the microcomputer 2 proceeds to step S′1, and the time T′1 is set as the start time of the medication function, and the elapsed time from that time is started to be measured. Then, it is determined in step S′2 whether or not the elapsed time from the measurement start time has reached a predetermined time T′7. If the voltage of the storage battery 4 does not decrease and the time T'7 is exceeded as it is, the process proceeds to step S'3, and the microcomputer 2 outputs a control signal to the display circuit 6 to turn on the LED unit 16, The liquid crystal display unit 15 displays a warning by displaying the excess time. Thereafter, in step S′4, the microcomputer 2 determines whether or not the user has performed the SW operation of the input unit 8 indicating the end of the process. If it is determined that the SW operation has been performed, the microcomputer 2 proceeds to step S′5. By outputting a control signal to the display circuit 6, the LED unit 16 is extinguished, and the display of the excess time is ended, thereby terminating the warning display and END.
(Second operation)
Next, the second operation of this embodiment will be described with reference to FIGS. 9, 10, 11, 13, and 14. FIG. In the second operation of this embodiment, a warning is displayed after the next medication time has elapsed since the medication function was executed, and the elapsed time since the medication function was executed is measured. During this time, the elapsed time measurement is interrupted by the voltage of the storage battery 4 of the watch dropping below a predetermined threshold, but the watch power is then restored by the next medication time, and the elapsed time measurement is continued. The warning display is executed after the medication time has elapsed. A case will be described in which the warning display is turned off by the user operating the input unit 8 at this time.

  The operation is the same as that described above until time T'1, and the description thereof is omitted. When the voltage of power storage unit 4 becomes lower than a predetermined threshold at time T ′ 2, power supply state detection circuit 3 detects a voltage drop and outputs a detection signal to microcomputer 2. The microcomputer 2 executes processing from START in FIG. 10 based on the detection signal detected by the power supply state detection circuit 3. In step SS′1, the microcomputer 2 detects the detection signal from the power supply state detection circuit 3 that is output when the voltage of the power storage unit 4 is lower than the predetermined threshold value. Therefore, the microcomputer 2 proceeds to step SS′2. A process of transferring information to the nonvolatile memory 7 is executed.

  Next, information transferred to the nonvolatile memory 7 in step SS'2 will be described with reference to FIG. In the microcomputer 2, the time measuring means includes information on the current time information such as year, month, day, hour, minute, and second. A plurality of functions can be set in the information processing means, and a flag indicating whether or not each function is operating is set. Among the plurality of functions, there is a medication notification function, and the measurement start time information is stored for the medication notification function. Currently, since only the medication notification function is operating, the flag there is 1, and the flags for other functions are 0. In the present embodiment, when the power supply state detection circuit 3 detects that the voltage of the power storage unit 4 is lower than a predetermined threshold value, the control means in the microcomputer 2 displays the information in the time measuring means and the information in the information processing means. Transfer to the non-volatile memory 7.

  After each information is transferred to the non-volatile memory 7, at time T'3, the processing of the microcomputer 2 proceeds to step SS'3. Then, the power supply from the power storage unit 4 to each circuit is stopped, and END is set.

  Next, when the voltage of the power storage unit 4 returns to a predetermined threshold value or more due to charging by the solar battery 9 at time T ′ 4, the power supply state detection circuit 3 detects the voltage return and outputs a detection signal to the microcomputer 2. The microcomputer 2 restarts the power supply from the power storage unit 4 to each circuit based on the detection signal detected by the power supply state detection circuit 3, and executes the process again from START in FIG.

  The processing of the microcomputer 2 proceeds to step SS'1. At this time, since the voltage of the power storage unit 4 is equal to or higher than a predetermined threshold value, the process proceeds to step SS′4. In step SS'4, the return of the power storage unit (power supply voltage) 4 is detected, and the process proceeds to step SS'5 at time T'5.

  At time T ′ 5, the microcomputer 2 outputs an operation command signal to the time information acquisition circuit 11. As a result, the time information acquisition circuit 11 operates to receive radio waves including time information obtained from the receiving antenna 12. Next, in step SS′6, the microcomputer 2 acquires the time information obtained by the time information acquisition circuit 11, and in step SS′7, the information in the nonvolatile memory 7 stored before the voltage of the power storage unit 4 decreases. Is read.

Next, information read from the nonvolatile memory 7 in step SS′7 will be described with reference to FIG. The control means in the microcomputer 2 includes the year, month, day, hour, minute, and second information as current time information from the time information acquisition circuit 11 and the time when the power supply voltage stored in the nonvolatile memory 7 is lowered. Information such as year, month, day, hour, minute, and second is transferred to the comparison means.
Further, the control means in the microcomputer 2 transfers the information stored in the nonvolatile memory 7 to the information processing means as it is when the power is lowered. Specifically, measurement start time information is transferred for operation flags of a plurality of functions and a medication notification function. The flag is 1 because only the medication notification function is operating as a state before the power supply voltage is lowered, and the flag is 0 because the other functions are not operating. Note that the time information obtained by the time information acquisition circuit 11 is transferred to the time measuring means in the microcomputer 2 by the control means, and the time measuring operation is resumed.

  Next, in step SS′8, the microcomputer 2 is measuring the elapsed time from the execution of the medication function before the power supply voltage is lowered by the operation flag of each function acquired from the nonvolatile memory 7. In step SS′9, the current time information acquired by the time information acquisition circuit 11 is compared with the time information of the nonvolatile memory 7 which is the time information when the power supply voltage decreases, and the power storage unit 4 The elapsed time when the diver watch was not operating is calculated.

Next, at time T′6, the processing of the microcomputer 2 proceeds to step SS′10. In step SS′10, the elapsed time from the measurement start time T′1 is taken into account, taking into account the elapsed time that the diver clock was not operating, obtained from the medication function execution time T′1. It is determined whether or not a predetermined time T′7, which is the next medication time, has been reached. Thereafter, when the time T′7 is exceeded, the microcomputer 2 shifts the processing to step SS′11 and outputs a control signal to the display circuit 6 to turn on the LED unit 16 and the liquid crystal display unit 15 exceeds it. The warning display is executed by displaying the time. Thereafter, in step SS′12, the microcomputer 2 determines whether or not the user has performed the SW operation of the input unit 8 indicating the end of the process. If it is determined that the SW operation has been performed at time T′8, the microcomputer 2 proceeds to step SS′13. The microcomputer 2 outputs a control signal to the display circuit 6 to turn off the LED unit 16 and finish displaying the excess time. Further, in the information processing means of the microcomputer 2, the medication notification function flag is reset to 0 and becomes END.

In the third operation of this embodiment, a warning is displayed after the next medication time has elapsed since the execution of the medication function, and the elapsed time since the medication function was executed is measured. During this time, the elapsed time measurement is interrupted when the voltage of the storage battery 4 of the clock drops below a predetermined threshold, but after that, the warning power is displayed indicating that the time is exceeded by the power supply of the clock returning after the next medication time T'7. Execute. A case will be described in which the warning display is turned off by the user operating the input unit 8 at this time.

  The third operation in FIG. 12 is the same as the second operation in FIG. 11 from time T′1 to time T′3, and thus the description is omitted, and the operation from time T′7 will be described. At T′7, since the voltage of the power storage unit 4 is lower than the predetermined threshold value, the microcomputer 2 does not operate.

  Next, at time T′9, the voltage of power storage unit 4 returns to a predetermined threshold value or more. Since the time T′9 to the time T′10 are the same as the time T′4 to the time T′5 of the second operation, the description is omitted, and the operation from the time T′11 will be described.

  At time T′11, the process of the microcomputer 2 proceeds to step SS′10. In step SS′10, the elapsed time from the measurement start time T′1 is taken into account, taking into account the elapsed time that the diver clock was not operating, obtained from the medication function execution time T′1. It is determined whether or not a time T′7 that is the next medication notification time has passed. At this time, since the time T′11 has passed the time T′7 which is the next medication notification time, the microcomputer 2 shifts the processing to step SS′11 and outputs a control signal to the display circuit 6. Then, the LED unit 16 is turned on, and the liquid crystal display unit 15 displays an excess time to display a warning. Thereafter, in step SS′12, the microcomputer 2 determines whether or not the user has performed the SW operation of the input unit 8 indicating the end of the process. If it is determined that the SW operation has been performed at time T′12, the microcomputer 2 proceeds to step SS′13. The microcomputer 2 outputs a control signal to the display circuit 6 to turn off the LED unit 16 and finish displaying the excess time. Further, in the information processing means of the microcomputer 2, the medication notification function flag is reset to 0 and becomes END.

  In the above embodiment, a diver watch has been described as an example. However, the present invention is not limited to this example. For example, an electronic ticket for amusement reservation at an amusement park, a rental video return notification card, etc. It is possible to use.
