Description

  The present invention relates to a time recorder that records a time for entering a company, a time for leaving a company, and the like on a time card, and more particularly, to a time recorder having a time correction function using a radio timepiece.

  In a time recorder equipped with a time correction function using a radio clock, for example, standard time information by a standard radio wave is received at a predetermined reception time (several times a day) and displayed on the display unit based on this standard time information. The correct time is corrected and the correct time is displayed.

  Here, the standard radio wave is transmitted in a long wave band of several tens of kHz or a short wave band of 1 to 15 MHz in order to provide a frequency standard and a standard of time information in various countries around the world. This time information generally includes information such as time, date, year, day of the week, leap second, and daylight saving time. In Japan, a standard radio wave JJY (registered trademark) is transmitted from two transmitting stations at 40 kHz and 60 kHz by an independent administrative agency information communication mechanism.

  The standard radio wave JJY is a serial digital signal in which a 1 Hz time code is applied to a 40 kHz or 60 kHz carrier wave by 10: 1 AM modulation, and 1 second is 1 bit and 60 bits (1 minute) is 1 frame. It is. The time code expresses minute, hour, day of the week, day of the year (one year), year of the year, leap second information, etc. in binary numbers (BCD (Binary Coded Decimal Notation) positive logic). This time code consists of three types of duty ratios, and 20% duty is a marker (M) corresponding to the rising edge of the minute (0 seconds per minute) and 9 seconds, 19 seconds, 29 seconds, 39 seconds, 49 seconds The position marker (P0 to P5) corresponding to the rising edge is represented. The 50% duty represents a binary 1 and the 80% duty represents a binary 0. The rising edge of each bit is adjusted so as to be synchronized with UTC.

  The long-wave radio wave used in the standard radio wave is received at the reception point by combining the ground wave transmitted along the ground surface and the spatial wave reflected and transmitted by the ionosphere (D layer).

  At near-field reception points within 200 km from the transmission point, the intensity of the spatial wave is lower than the surface wave, so the reception intensity is stable. At night, the spatial wave intensity increases, but the fluctuations are not so great. In the range of about 700 km beyond the transmission point, the intensity of the surface wave and the spatial wave are almost the same or slightly higher.

  Since the phase is different between the surface wave and the spatial wave (because the propagation distance is different), the combined received intensity varies.

  There is little fluctuation during the day when the ionospheric influence is small, and the fluctuation is greater at night, although the reception level increases.

  Further, in the distance, the intensity of the spatial wave is larger than the intensity of the surface wave, and the fluctuation of the received intensity is observed greatly throughout the day and night.

  The apparent height of the D layer ionosphere changes during the day and at night. It has also been observed that the summer period is different from other periods. During periods other than summer, although the fluctuation increases, the intensity of the spatial wave increases, so that the radio timepiece is easier to receive at night.

  In a conventional time clock with a radio clock, a radio clock unit including a radio receiving antenna and a radio signal relay board is connected to the time recorder main body by wire, and radio wave reception control is performed on the time recorder main body side.

  However, in a conventional time clock with a radio clock in which the radio clock unit is connected to the time recorder body by wire, the success or failure of radio wave reception depends on the radio wave sensitivity near the installation location of the time recorder body.

  Normally, time recorders are installed in places where many people come and go, such as the entrances and exits of offices and changing rooms, but they are not necessarily in a position that is advantageous for receiving radio waves, such as by the windows. May occur. In addition, there is a problem that when a home appliance is in the vicinity, the standard radio wave cannot be received due to the influence of noise from the home appliance. For this reason, when the time is corrected by the standard radio wave, it is necessary to take measures such as moving the time recorder near a window where there is no home appliance in the vicinity. However, there are problems in terms of installation space at the destination and usability at the destination of the user.

  Therefore, the applicant of the present application is provided with a mounting unit that is detachably mounted on the time recorder main body as a time recorder having a standard radio wave receiving function that does not need to consider the reception of the standard radio wave when installing the time recorder. A time recorder provided with time measuring means for measuring time and standard radio wave receiving means for receiving standard radio waves, and correcting the time of the time measuring means based on standard time information contained in the standard radio waves received by the standard radio wave receiving means (For example, refer to Patent Document 1).

It is determined whether or not the time has elapsed (step S3), and after waiting for a predetermined time, for example, 5 minutes in the low power consumption mode, the operation of receiving the standard radio wave by the time radio wave receiving circuit 222 is resumed, and the above step Returning to S1, the standard radio wave intensity received by the standard radio wave receiver 220 is determined.

  Further, when the control unit 210 determines that the standard radio wave received by the standard radio wave receiver 220 is strong in the standard radio wave strength determination process of step S1, the standard radio wave receiver 220 is provided. The standard radio wave reception process is performed (step S4), and it is determined whether the standard radio wave has been successfully received (step S5).

  If the standard radio wave reception unit 220 fails in the standard radio wave reception process, the control unit 210 returns to step S1 and again determines the standard radio wave intensity received by the standard radio wave reception unit 220. If the standard radio wave reception unit 220 fails in the standard radio wave reception process, the external unit 20 is set in the low power consumption mode and enters a standby state.

  Note that the standard radio wave strength determination process in step S1 performed at the start of the standard radio wave reception operation may be omitted. If it is determined in step S5 that the standard radio wave has been successfully received, it is determined that reception of the standard radio wave has failed. The process then proceeds to step S2 and the external unit 20 is set in the low power consumption mode and waits for a predetermined time. After that, the standard radio wave receiving operation by the time radio wave receiving circuit 222 may be resumed. When the standard radio wave receiving operation is performed again, the standard radio wave strength determination process in step S1 may be omitted.

  Here, an LED light emitting unit 250 is provided as a notification means indicating that the standard radio wave receiving unit 220 is receiving standard radio waves, and the control unit 210 of the external unit 20 includes the standard radio wave shown in FIG. When the receiving unit 220 receives the standard radio wave, the first light emitting unit 251A of the LED light emitting unit 250 is turned on, and when the standard radio wave receiving unit 220 succeeds in receiving the standard radio wave, the second light emitting unit It has a function of a notification control unit 210F that controls to turn on the third light emitting unit 251C when the standard radio wave receiving unit 220 fails to light the 251B and the standard radio wave receiving unit 220 fails.

  In the time recorder 100, the ten control units 110 of the time recorder main body perform the time correction processing based on the standard time information obtained by receiving the standard radio wave from the standard radio wave receiving unit 220 in the external unit 20. Time information obtained by measuring time by the external time measuring unit 210A corrected by the unit 210E is acquired as time information for correction from the external unit 20 via the external connection interface unit 11F, and the main unit time measuring The time correction processing unit 110G corrects the time information obtained by measuring the time by the unit 110A.

  Here, the control unit 110 of the time recorder main body 10 controls the operation of the external unit 20 according to the procedure shown in the flowchart of FIG.

  The time recorder 100 includes a determination unit that determines whether or not the time information obtained by the standard radio wave reception unit is effective for correcting the time information of the time recorder main body 10. In this embodiment, when the external unit 20 is mounted on the time recorder main body 10, first, a connection confirmation process is performed between the time recorder main body 10 and the external unit 20 (step S11), and then the time recorder main body is connected. The control unit 110 sends a status acquisition command, and indicates whether the attached external unit 20 has successfully received the standard radio wave, or information indicating the status of the external unit 20 such as during reception. Obtain (step S12).

  Next, the control unit 110 of the time recorder body 10 determines whether or not the attached external unit 20 has successfully received the standard radio wave based on the state information acquired from the external unit 20 (step S13) If the reception of the standard radio wave is successful, a clock request command is sent, and the standard radio wave receiving unit 220 receives the standard radio wave in the external unit 20 and is based on the standard time information obtained. The current time information obtained by measuring the time by the external time measuring unit 210A corrected by the time correction processing unit 210E is acquired as time information for correction from the external unit 20 through the external connection interface unit 110F. (Step S14).

  Next, the control unit 110 of the time recorder main body 10 compares the current time information acquired from the external unit 20, that is, the time information for correction, and the current time information obtained by measuring the time by the main body side time measuring unit 110A. It is determined whether or not there is a difference greater than the set time (step S15).

  In the determination process of step S15, if there is no difference between the correction time information and the current time information over the set time, the process immediately proceeds to step S20 and the correction time acquired in step S14. Using the time information, the time correction processing unit 110G corrects the time information obtained by measuring the time by the main body time measuring unit 110A.

  Here, in the time recorder 100, the power source detection unit 240 provided in the external unit 20 detects a driving power source in which the external unit 20 can operate at least in the low power consumption mode. Based on the detection output from the power source detection unit 240, the control unit 210 corrects the time information obtained by the main body side timekeeping unit 110A of the time recorder main body 10 using the time information obtained by the external main body side timekeeping unit 210A. A flag indicating whether or not it is valid may be set.

  The control unit 110 of the time recorder main body 10 maintains the standby state in the low power consumption mode by determining the validity of the correction time information based on the flag in the determination process of step S13. If it is not possible, it is possible to prevent time information from being corrected using incorrect time information for correction.

  Further, in the determination process of step S15, if there is a difference of a set time or more between the time information for correction and the current time information, the control unit 110 of the time recorder body 10 performs time correction. The confirmation screen is displayed on the display unit 130, an input as to whether or not the time correction is performed by the operation of the operation unit 140 is received, and whether or not the time correction is performed based on the operation input of the operation unit 140 is received. Is determined (step S16).

  As a result of the determination processing in step S16, the control unit 110 of the time recorder body 10 has an error in the time information for correction, and there is a difference of a set time or more between the time information for correction and the current time information. If there is, it is possible not to correct the time information obtained by measuring the time by the main body side timing unit 110A. Note that time correction may be performed regardless of the time difference.

  When performing time correction, the control unit 110 of the time recorder main body 10 determines whether or not the time information for correction and the current time information straddle a day (step S17).

  In the determination process of step S17, when the time information for correction and the current time information do not cross the day, a clock request command is sent and corrected from the external unit 20 via the external connection interface unit 110F. Time information is acquired again (step S19), and the time correction processing unit 110G corrects the time information obtained by measuring the time by the main body time measuring unit 110A using the acquired correction time information. (Step S20) After that, a unit operation command is sent to set the operation mode of the external unit 20 after removal (Step S22).

  In the determination process of step S17, when the correction time information and the current time information straddle a day, after waiting for a predetermined time or more, the process proceeds to step S19, and the external unit 20 Time information for correction is acquired again, and using the acquired time information for correction, the time correction processing unit 110G corrects the time information obtained by measuring time by the main body side time measuring unit 110A.

  That is, when the time information for correction and the current time information straddle the date, if the time correction is performed as it is, the date change time is straddled and the previous day is reversed or the next day is reached. In such a case, since the process associated with the date change time of the time recorder main body 10 may be double-processed or not processed, the time information for correction is acquired again after a predetermined time and the time correction process is performed. Note that this processing may not be required depending on the processing structure of the time recorder body 10.

  Further, the control unit 110 of the time recorder body 10 determines that the attached external unit 20 has failed to receive the standard radio wave as a result of the determination process in step S13, or the result of the determination process in step S13. When time correction is not performed, a date setting command or a clock setting command is sent to set the date and time of the external unit 20 (step S21), and then the control unit 110 of the time recorder main body 10 An operation command is sent to set the operation mode of the external unit 20 after removal (step S22).

  By the date and time setting process in step S21, the time information and calendar information of the time recorder main body 10 and the external unit 20 can be matched and synchronized.

  Here, in the time recorder 100, the external unit 20 can be attached to and detached from the time recorder body 10, and the external connection male connector 15 and the main body connection female connector 21 are electrically connected to each other, thereby providing an external connection interface. Serial communication is performed via the unit 110F and the main unit connection interface unit 210C, and calendar information, time information, radio wave reception history information, setting information, etc. are transmitted between the control unit 210 of the external unit 20 and the control unit 110 of the time recorder main unit 10. The external connection interface unit 110F and the main body connection interface unit 210C are configured to be a non-contact communication interface using radio waves or light as a communication medium, or between the control unit 210 of the external unit 20 and the recorder main body 10. Wired connection with the control unit 110 It may be an interface.

  Further, in this embodiment, in the time recorder 100, the power supply circuit 230 as the built-in power supply of the external unit 20 includes a charging circuit 230A that charges the storage means that can store electricity using an electric double layer capacitor, a secondary battery, etc. The power supply means provided in the time recorder main body 10 in the state of being mounted on the time recorder main body 10, that is, the power storage means is charged by the electric power supplied from the power supply circuit 150, but the power supply source is the time recorder main body 10. Alternatively, an AC adapter or a charging unit may be used as an external power source. For example, the external unit 20 may be attached to a cradle placed near a window and charged. Further, the power supply circuit 230 of the external unit 20 may use a primary battery as a power source.

  In the time recorder 100, the notification light control unit 210F controls the LED light emitting unit 250 to notify the user that the standard radio wave receiving unit 220 is receiving standard radio waves. Instead of LED lighting / flashing / color change by 250, notification by LCD display or sound by a buzzer may be used.

  In the state where the external unit 20 is mounted on the time recorder body 10, the external unit 20 is set to the automatic reception mode, and the standard time +30 minutes is received 24 hours a day for every hour. The radio wave receiving unit 220 performs a standard radio wave reception operation, and transmits time information to the time recorder body 10 after normal reception. During the reception, the display content of the display unit 130 of the time recorder body 10 is not changed. The reception frequency is given priority to the previous successful reception frequency.

  The time recorder main body 10 is obtained by measuring the time by the main body side time measuring section 110A with the correction time information acquired from the external unit 20 through the main body connection interface section 210C and the external connection interface section 110F. Whether or not the time information has been corrected within a predetermined period can be displayed on the display unit 130 for notification, for example. As a result, when the time recorder body 10 is used with the external unit 20 mounted, if there is no indication that the time information has been corrected, the standard radio wave intensity at the time recorder installation location is Since it is weak, it is possible to urge the user to remove the external unit 20 and bring it to a place where the intensity of the standard radio wave is strong and receive it.

  Further, when the forced reception mode is set with the external unit 20 mounted on the time recorder body 10, the external unit 20 immediately performs a standard radio wave reception operation by the standard radio wave receiving unit 220, and after normal reception. Time information is transmitted to the time recorder body 10. During reception, the display content of the display unit 130 of the time recorder main body 10 is changed. However, when there is a key operation or card insertion during forced reception, priority is given to the reception of key operation input and the process of stamping, and the process returns to the forced reception mode after the process ends. Similarly, the display of the display unit 130 also prioritizes key operation input acceptance and stamping processing.

  In addition, the control unit 210 of the external unit 20 performs reception by alternately switching the frequency selection of 40 KHz and 60 KHz every several seconds in the standard radio wave receiving operation of the standard radio wave receiver 220. Immediately after the frequency switching, there is a case where the accurate reception cannot be performed due to the influence of the previous frequency intensity. Therefore, the data for a certain period immediately after the frequency switching is skipped and the subsequent data reading process is performed. Thereby, when the external unit 20 is removed and a place where the strength of the standard radio wave is strong is searched, the reception sensitivity of the radio wave condition with the better radio wave condition of 40 KHz and 60 KHz is shown in real time regardless of whether the usage environment is east or west in Japan it can.

  In addition, in order to correct the time of the time recorder 100 and other electronic devices by one external unit 20, time information obtained from the standard time radio wave received once by the external unit 20 is stored in a memory or the like. You may make it hold | maintain to a means for a predetermined period. At this time, the time information held in the storage means may be overwritten when a new standard radio wave is received and the time information can be obtained.

  The standard radio wave may receive AM wave, FM wave time signal information, etc. as an example other than the above.
