[0002]
[Prior art]
Conventionally, the time information of one or a plurality of time measuring means such as one or a plurality of watches or clocks existing in a predetermined area such as a home via a time information relay device is set to a correct time (official standard time information ) A time information management system is proposed. For example, Japanese Patent Laid-Open No. 10-311886 discloses a time information management system as described above.
[0003]
Hereinafter, a conventional technique similar to that disclosed in JP-A-10-31886 will be described with reference to the system block diagram of FIG.
[0004]
In FIG. 4, time information generating means 2 for generating information including standard time information, which is information generating means, is provided independently of the time information generating means 2, and first time measuring means 4 and receiving means 9 are provided. The time information is a time information relay device configured to receive the time information including the standard time information by the receiving means 9 and to send the time information of the first time measuring means 4. One or a plurality of second time measuring means 5 fixedly or movably arranged around the time information relay apparatus independently of the adjustment means 3 and the time information adjustment means 3 as the time information relay apparatus. , 5-2,..., 5-n, and the time information adjustment unit 3 as the time information relay device receives the time information from the time information generation unit 2 via the reception unit 9. Standard time information from the time information signal The standard time information extracting means 6 to be output, and the first time counting built in the time information adjusting means 3 as the time information relay device using the standard time information extracted from the standard time information extracting means 6 Time which is time information sending means for sending information including time information from the standard time adjusting means 7 for correcting the time information of the means 4 to correct standard time information and the first time measuring means 4 set to the correct standard time. Information output means 8, and the time information included in each of the second time measuring means 5-1, 5-2,.

[0005]
That is, the above-described time information management system 1 includes a wall clock 5-1, which is a fixed second measuring means existing in a predetermined area 10 such as at home, and a microwave oven 5-2 with a clock function. Alternatively, one or more of a watch 5-3, a portable clock 5-4, and a remote control 5-5 for home appliances with a clock function, which are portable mobile bodies that can move freely within the predetermined area 10, are provided. There has been proposed a time information management system 1 that can be easily or sequentially set to accurate standard time information.
[0006]
Further, the time information generating means 2 is not particularly limited, but the government agencies and official agencies of countries around the world including Japan are in a specific country or in a region where the same standard time is used. Any structure may be used as long as it has a function of generating extremely accurate standard time information to be output for use.

FIG. 2 is a system block diagram disclosing further details of the configuration of the transmission / reception frequency control means 12 in FIG. 1, which is an important component of the time information relay device and the time information management system according to the present invention.
The system block diagram of FIG. 2 will be described below.
[0015]
The transmission / reception frequency control means 12 includes a reception time storage circuit 122 that stores a preset reception time, for example, every hour (24 times a day), and a preset, for example, every ten minutes (144 a day). Transmission time memory circuit 123, current reception time memory circuit 121, current transmission time memory circuit 124, and preset hourly intervals (24 times a day). A coincidence circuit for reception 125 that performs coincidence detection between the reception time and the current time, and a coincidence circuit for transmission 126 that performs coincidence detection between a preset transmission time every 10 minutes (144 times a day) and the current time, Consists of.
[0016]
The operation of the system block diagram of FIG. 2 is as follows. Current time information of the first time measuring means 4 is sent to the reception current time storage circuit 121 and the transmission current time storage circuit 124 via the I input terminal every minute ( It is desirable to detect whether the reception coincidence circuit 125 or the transmission coincidence circuit 126 detects coincidence with the time information to be received or transmitted, which is preset in the reception time storage circuit 122 or the transmission time storage circuit 123. Do. When a coincidence between a preset reception time every hour (24 times a day) and the current time is detected, the reception coincidence circuit 125 controls the reception means 99 via the X output terminal. When the coincidence between the preset transmission time every 10 minutes (144 times a day) and the current time is detected, the transmission coincidence circuit 126 sends the time information transmission means 88 via the Y output terminal.

As a result, the receiving means 99 receives information including the standard time information from the time information generating means 2 at a frequency of 24 times a day every hour, and the time information transmitting means 88 is 144 times a day every 10 minutes. Information including standard time information at a frequency is a clock 5-1 which is a second clocking means fixedly provided in a predetermined area 10 such as in the home from the time information transmission means 88, and an electronic device with a clock function. The data is transmitted to the range 5-2 or the watch 5-3 provided so as to be freely movable within the predetermined area 10, the portable clock 5-4, and the remote control 5-5 of the home appliance with a clock function.
[0018]
Next, transmission information by radio waves including long wave standard time information, which is operated and managed by the Ministry of Posts and Telecommunications Communications Research Laboratory (CRL), which is one of the specific means of the time information generating means 2, will be described in detail.
[0019]
The current Japanese longwave standard radio waves are experimentally transmitted from Sanwa Town, Ibaraki Prefecture under the operation of the Communications Research Laboratory (CRL) of the Ministry of Posts and Telecommunications. It is the accumulated date from the day (see FIG. 3C).
[0020]
The time data is transmitted at 1 bit / second, and one frame is one frame, and the information of the accumulated date from the above-mentioned minute / hour / January 1 is provided as a BCD code in this frame. The transmitted data includes a marker of P code in addition to 0 · 1. This P code has several places in one frame, and it is the minute (0 seconds), 9 seconds, 19 seconds, 29 seconds, 39 seconds. , 49 seconds and 59 seconds. This P code appears continuously only once at 59 seconds and 0 seconds in one frame, and the position where this P code appears continuously becomes the minute position. In other words, time data such as minute / hour data is determined in the frame with reference to this minute position, so that the time data cannot be extracted unless the minute position is detected.
[0021]
Next, the long wave standard radio wave formalized in 1999 will be described.
[0022]
Japan's standard radio wave is currently an experimental station as described above, but is scheduled to become an official station in 1999 for the purpose of advanced use of the standard radio wave. Along with this, in addition to the current (experimental station) transmission data, the last two digits, day of the week, minute parity, hour parity, spare bits scheduled to be used when daylight saving time is introduced, and leap seconds are added (FIG. 3 ( a)). Also, wave stop information for interrupting the transmission of radio waves was added at 15 minutes and 45 minutes per hour (see FIG. 3B). The data transmission method is the same as the current method, that is, one frame per minute at 1 bit / second, even if it is an official station. Of these newly established information, spare bits, leap second information, and stop information will be described in particular.
[0023]
As shown in Table 1, the reserved bits use SU1 and SU2. These are prepared for future information expansion. When this bit is used in daylight saving time information, when SU1 = SU2 = 0, there is “no change to daylight saving time within 6 days”, and when SU1 = 1 · SU2 = 0, there is “change to daylight saving time within 6 days”, When SU1 = 0 and SU2 = 1, the information format is “daylight saving time in progress”, and when SU1 = SU2 = 1, “daylight saving time ends within 6 days”. Daylight saving time has not been introduced yet in Japan, and it is still unknown, but when it comes to European summertime changes, it is often done in the middle of the night.
[0024]
[Table 1]

[0025]
Next, as shown in Table 2, the leap second uses 2 bits of LS1 and LS2, and when LS1 = LS2 = 0, “the leap second is not corrected within one month”, and when LS1 = 1 · LS2 = 0 “There is a negative leap second (deletion) within one month”, that is, one minute is 59 seconds, and when LS1 = LS2 = 1, “There is a positive leap second (insertion) within one month”, that is, one minute is 61 seconds. The information form is as follows. The leap second correction timing has already been determined, and is to be performed immediately before January 1 or July 1 of the UTC time. Therefore, in Japan time (JST), it will be performed immediately before 9:00 am on January 1 or July 1.
[0026]
[Table 2]

[0027]
As shown in (a), (b), and (c) of Table 3, ST1, ST2, ST3, ST4, ST5, and ST6 are used as the stop information. In ST5 and ST6, the stop information of the stop period is provided. First, the stoppage start notice will be described. When ST1 = ST2 = ST3 = 0, “No stoppage is planned”, and when ST1 = ST2 = 0 · ST3 = 1, “Stop within 7 days”, ST1 = 0 · ST2 = 1・ When ST3 = 0, “Stop within 3 days from 3”, ST1 = 0 ・ When ST2 = ST3 = 1, “Stop within 2 days”, When ST1 = 1 and ST2 = ST3 = 0, “Stop within 24 hours” In the case of “stop”, ST1 = 1 · ST2 = 0 · ST3 = 1 “stops within 12 hours”, and ST1 = ST2 = 1 · ST3 = 0 indicates “stops within 2 hours”. Next, the stop time notice is “only daytime” in ST4 = 1, and “all day or no stoppage plan” in ST4 = 0. Next, the stop period notice is “no stop plan” at ST5 = ST6 = 0, “stop for 7 days or longer or unknown period” at ST5 = 0 · ST6 = 1, “ “Stop within 2 to 6 days”, and ST5 = ST6 = 1 indicates “stop in less than 2 days”.
[0028]
[Table 3]
