Description

Time recorder

The present invention relates to a time recorder for recording a working time or an after-hours time or the like on a time card, and more particularly to a time recorder having a time correction function using a radio wave clock.

Priority is claimed on the basis of Japanese Patent Application No. 2012-144329 and Japanese Patent Application No. 2012-14430, the entire contents of which are hereby incorporated by In the application.

In a time recorder including a time correction function using a radio wave clock, for example, standard time information obtained by standard radio waves is received at a predetermined reception time (several times a day), and the display unit is corrected based on the standard time information. Show the moment so that it shows the correct moment.

Here, the standard radio wave is transmitted in a long wave band of 10 kHz or a short wave band of 1 to 15 MHz, and is provided with standards for frequency standards and time information in countries around the world. At this moment, the information generally includes information such as time, date, year, week, leap second, and summer time. In Japan, it is an independent administrative agency information communication agency, with 2 delivery stations at 40 kHz and 60 kHz to transmit standard radio wave JJY (registered trademark).

The standard radio wave JJY is a time hopping code of 1 Hz, and the AM modulator is applied to the carrier of 40 kHz or 60 kHz at 10:1, and is a string of 1 frame when 1 second is set to 1 bit and 60 bits (1 minute) is set to 1. The digital signal of the column. The time code is expressed in binary (Bin (Binary Coded Decimal Notation)), which is divided into time, hour, week, total day (1 year), Western calendar year, and leap second information. The time code is composed of three energy ratios, and the 20% energy rate indicates a mark (M) corresponding to the start of the whole minute (0 seconds per minute), and corresponds to 9 seconds, 19 seconds, 29 seconds, 39 seconds, 49 seconds. The starting position mark (P0~P5), the 50% energy rate indicates that the binary value of 1,80% indicates zero in binary. In addition, the beginning of each element is adjusted to be synchronized with UTC.

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

The spatial wave intensity is lower than that of the ground wave at a short-distance reception point of about 200 km compared to the transmission point, so the reception strength is stable. Although the spatial wave intensity increases at night, the change does not become so large. The intensity of the ground wave and the spatial wave are almost the same, or the ground wave becomes a slightly stronger level than the range where the transmission point is about 700 km ahead.

Since the ground wave and the spatial wave are different in phase (due to the different transmission distances transmitted), the synthesized reception strength changes.

The daytime system with less impact on the ionosphere has less variation, but at night Although the level of reception increases, the change will become larger.

In the farther distance, the intensity of the spatial wave is greater than the intensity of the ground wave, and the variation of the reception intensity is greatly observed through day and night.

The ionosphere of the D layer is changed during the day and night, and the height of its appearance changes. In addition, it is observed that during the summer period, it is different from other periods. In the period other than the summer, although the fluctuation increases, the intensity of the spatial wave increases, so the radio clock is easy to receive at night.

In a conventional time recorder with a radio wave clock, a radio wave clock unit formed by a radio wave receiving antenna and a radio signal relay substrate is connected to the time recorder body by wire, and the radio wave receiving control is in the time recorder body. Side.

However, in a conventional time recorder with a radio wave clock in which the radio wave clock unit and the time recorder main body are wired, the radio wave reception depends on the radio wave sensitivity in the vicinity of the installation place of the time recorder main body.

Usually, the time recorder is installed in a place where many people enter and exit, such as the entrance and exit of the office or the locker room, but it is not necessarily a position such as a window that is conducive to radio wave reception, and there is a place at the standard time according to the place where it is installed. Radio wave reception produces a fault condition. Further, when the home electric appliance is located in the vicinity, there is a problem that the standard radio wave cannot be received due to the influence of noise from the home electric appliance. Therefore, when the time is corrected by the standard radio wave, it is necessary to move the time recorder to a window such as a window where there is no home electric appliance. However, there is a problem in the setting space of the mobile destination or the user's ease of use at the mobile destination.

Therefore, the applicant of the present invention has previously proposed a time recorder which is set for the time recorder and has a time recorder with a standard radio wave receiving function that does not need to consider the reception of standard radio waves. The installation unit is installed in the time recorder main body, and the installation unit is provided with a timing means for timing the time, and a standard radio wave receiving means for receiving the standard radio wave, and the standard radio wave received by the standard radio wave receiving means is received. The standard time information included is used to correct the timing of the timekeeping means (see, for example, Patent Document 1).

Poor (step S15).

In the determination process of the step S15, if there is no difference between the time information of the correction and the current time information, the process proceeds to step S20, and the correction for the correction acquired in the above step S14 is used. The time information is corrected by the time correction processing unit 110G, and the time information obtained by counting the time by the main body side time measuring unit 110A is corrected.

In addition, the power circuit 230 of the external unit 20 may also be a The secondary battery acts as a power source.

Further, in the time recorder 100, the notification light-emitting unit 250 is controlled by the notification control unit 210F to notify the user that the standard radio wave reception unit 220 is a standard radio wave reception operation, but may be utilized. Instead of the LED being turned on/off, the LED is turned on/off by the display of the LED display unit 250 for display or display by the sound of the buzzer.

In the state in which the time recorder main body 10 is provided with the external unit 20, the external unit 20 sets the automatic receiving mode, and the whole point + 30 minutes is used as the receiving time, 24 hours per hour, 1 hour. The standard radio wave receiving unit 220 performs a standard radio wave receiving operation, and transmits the time information to the time recorder main body 10 after the normal reception. However, in the reception, the display content of the display unit 130 of the time recorder main body 10 described above does not change. In addition, the frequency of reception is such that the previous success rate of reception is prioritized.

The time recorder main body 10 is formed as time information for correction that can be obtained by the external unit 20 through the main body connection interface unit 210C and the external connection interface unit 110F, and is displayed on the display unit 130 by the main body, for example. The time measurement unit 110A corrects the time information obtained by counting the time for a predetermined period of time to perform notification. Therefore, when the time recorder body 10 is held in the state in which the external unit 20 is mounted, if there is no display of the fact that the time information has been corrected, the intensity of the standard radio wave in the installation place of the time recorder is higher.
