DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a power/end information 1111 knowledge control system for notifying calendar information such as year, month, day, 1 hour, 5 minutes, and 1 second from a center to a terminal.

Conventional technology and problems On various terminals, in September 2017, "15:03.

This type (1) often requires calendar information such as seconds. For example, in 1111 communication between terminals, when specifying 11 o'clock to automatically start communication, or when im (ij
l l 11. When recording information such as '1' or communication time, power/time information is required. It is conceivable to provide a calendar function such as a clock device on each terminal, but rather than providing a monthly/annual function such as an hour device on each terminal, Terminal costume]・
There are +11 people and 11 synchronized power 1/under functions of each terminal-I! Number'1. This has the disadvantage that the synchronization method is complicated.

Therefore, it has been adopted to provide a data center with a calendar function so that each terminal can receive calendar information.

In this J-Una calendar information 1Fll intelligence method, the calendar information including 1:01:09 on January 3, 2017 is transferred, so there is a large number of pieces of information to transfer, and the time required for transfer and This has the disadvantage that the traffic on the transfer path increases.

OBJECTS OF THE INVENTION The present invention aims (1) to enable efficient notification of calendar information from a center to a terminal.

Composition of the Invention The present invention provides a system for transmitting calendar information from a center having a power/reader function to an arbitrary number of terminals, in which the center is provided with means for identifying changing digit positions and digit contents of the calendar information. , the changed digit content information and its digit position information are sent to the terminal as calendar information, and in the terminal, the digit content information is set at the digit position indicated by the digit position information, and from the digit position The content of the lower digits is set as the initial value, and the calendar information is compressed and transferred, so the calendar information can be notified efficiently. Examples will be described in detail below.

Power to hold second calendar information [-nda register, 15
64: A monitoring point pointer that indicates the changing digit position of the I calendar information, 17 is a communication control unit, 21 is a 1ffl communication control unit of the terminal, 22 is an information processing unit, and 23 is a calendar Information Setting No. 111 (4).

A clock device is constituted by an oscillator 12, a calendar information generating section 13, and a calendar register 14. A calendar information processing section 15 monitors changes in the digit content of the monitoring point indicated by the monitoring point pointer 16, and When the digit content of a monitoring point changes, the digit position information and digit content information of the monitoring point are sent to the terminal via the communication control unit 17 as calendar information, and when the digit content of the monitoring point does not change, the The lower digit position information is sent to the terminal via the communication control unit 17 as calendar information.

In the terminals 118 to lIn, the information processing unit 22 processes the calendar information received via the communication control unit 21, identifies the digit position information, updates the digit content information in the calendar information setting unit 23, When this finger position information indicates a digit position other than the lowest digit, the contents of the digits lower than that digit are set to initial values under the control of the information processing section 22.

FIG. 3 is a flowchart of the center according to the embodiment of the present invention.
The calendar information processing unit 15 uses the clock (5) interrupt to determine whether the monitoring point has changed or not by checking the contents of the digit indicated by the %-viewpoint pointer 16, and if it has not changed, changes the position of the least significant digit. The least significant digit information including the information and its 111 content information is sent. Also monitoring 3. In the case of 'j, l', the calendar information section of the monitoring point sends out the digit position information and digit content information of the supervisor 1 viewpoint, and controls the movement of the monitoring point. This monitoring point movement occurs, for example, after the monitoring point is at the minute digit position and the 59th minute (:1), the monitoring point moves to the hour 111 position. Since the hour digit content will change later, when a change in the hour digit content is detected, the hour digit position information and digit content information are sent as calendar information. The monitoring point after reaching 23:59 on the 127131st is controlled to move to the year digit position.

FIG. 4 shows a flowchart of a terminal according to an embodiment of the present invention. The contents of the digits lower than the Ii (6) position indicated in the finger position information are set to initial values.The initial values are 0 for the hour 1 minute 2 seconds and 1 for the 1st day of the month.For example, the digit position If the information indicates the month and the digit content indicates 3, then 2
Since it is calendar information that shows the change from March to March, 3
In addition to setting the month, ``15:05:02'' is set as the initial value of 0:00:0 seconds on the 1st.

FIG. 5 is an explanatory diagram of the operation of the embodiment of the present invention. As shown next to the year, month, day, hour, minute, and second, the second digit position information of the lowest digit is set to [1-1, and the minute digit position information is set to [1-1]. "2", hour digit position information "3", day digit position information "4", month digit position information "
5", the year digit position information is 4 digits in the case of the Western calendar, so the lower digit position information is "6-1", and the L digit position information is "7".
This shows the case where For example, the sending calendar information at 19:10:25 on January 1, 1988 is +
988.1,1. +9. to, 25, but according to the present invention, it becomes r125J.

That is, the digit information "1" and the digit content information "25" are sent out as calendar information. Due to the passage of time t (7), the content of the lower digits of NO changes from 25 seconds to 26 seconds after the next one second, so the forwarding 44 calendar information in this case becomes N26J.

In this way, when the content of the least significant digit is 59 seconds and 4c, the transmitted calendar information becomes r159.1, and the monitoring point pointer 16 indicates the minute digit. After the next second, 10
minute to 11 minutes, the change in digit content for this minute is detected, digit position information + IJ is set to r2J, digit content information is set to [111], transmission calendar information is formed and sent to the terminal (8 In the terminal, since the digit position information is 121 indicating minutes and the digit content information is [111, it is set to 11 minutes and the digit content for seconds is initialized to 0.

One minute after the 11th minute has elapsed, the time will be 12 minutes, and the transmission calendar information will be r212j. When further time passes and the transmission calendar information reaches r259.1, the monitoring point pointer 1
6 is specified every time the hour digit position is specified. After the next one minute has passed, the time changes from 19:00 to 20:00, so the hour digit position information 131 and the digit content information r 20 J are sent as calendar information (8). The terminal that receives this calendar information sets the hour digit content to r20.1, and sets the minutes and seconds to the initial value of 0.

Calendar information can be transmitted for months and years by the same operation as described above, and since the changed digit position information and the digit content information are used as the transmitted calendar information, the amount of information to be transferred is small. Moreover, since the digit content information is transferred, errors will not accumulate.

As described in detail, the present invention provides means such as the calendar information processing unit 15 for identifying the changed digit position and digit content of the power 1 nonda information in the center, and the changed digit content information and its digit position. information as calendar information to the terminal, and in the terminal, digit content information is set in the digit position indicated by the digit position information, and digit content lower than the digit position is set to the initial value. The transmitted calendar information consists of changed digit position information and changed digit position information, and compared to the case of transmitting information (9) that includes the year, month, and day, the amount of transferred information is reduced by two times, This has the advantage that the time required for transfer and the traffic on the transfer path can be reduced. In addition, there is an advantage that there is no accumulation of differences between il and jt compared to the case where only the changed information is transferred. Therefore, it is possible to improve the overall efficiency of the system.
