Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, the time information setting method of the present invention comprises a time setting device 6 and an information processing system 8. The time setting device 6 includes a line connection means 1 for connecting to a time signal service of a public network, a time signal recognition means 2 for receiving voice and a specific frequency transmitted from the time signal service via the line connection means 1 and identifying time information. A counting means 3 which receives and sets the recognized time information and operates in synchronization with a clock signal for updating the time information of the connected information processing system; and the time information updated by the counting means 3. A first matching unit 4 for comparing the time information received from the time signal recognition unit 2 with the time information, and a time information of the information processing system 8 and a time information being updated by the counting unit 3 at a predetermined time. And second collating means 5 for performing the above.

The information processing system 8 issues a connection instruction to the line connection means 1 based on the designation, supplies a clock signal to the counting means 3, and when the matching result of the first matching means 4 matches, the counting means 3 uses the clock signal. The time information being updated is set in the own system, and the operation of the system is continued by the time information of the own system when the collation result of the second collation means 5 matches. And a control means 7 for newly setting time information being updated in the own system.

In the preferred embodiment of the present invention, it is desirable that the system can be controlled from a system which requires setting of time information. That is, if control can be performed from the system side, maintenance and operation including the present invention can be performed by performing collective management from the system.

First, the control of the line connection means 1 automatically enables connection and disconnection to the time signal service of the public network at the time of setting and checking according to the system operation schedule in accordance with the operation of the system. It is also possible to start the line connection means 1 by operating a system maintenance terminal or the like.

Secondly, since the first collating means 4 and the second collating means 5 collate time information that is constantly updated, they are collated by a hardware circuit. When the collation is performed by software processing, there is a possibility that an accurate collation may not be performed due to a processing delay. Therefore, a mode in which software dedicated to the collation processing is incorporated in the first collation unit 4 and the second collation unit 5 is adopted. Take. Further, control of the first collating means 4 and the second collating means 5 from the system side is necessary, and the collation result is notified to the system.

Third, the counting means 3 is constituted by a hardware circuit, and is operated by a signal which is the same as and synchronized with a clock signal used for updating time information used for clock management operation on the system side. The counting means 3 makes it easy to set and check the time information in the system.

Fourth, the time signal recognizing means 2 has a function of recognizing a time fixed tone of the time signal service and a function of voice recognition. In the voice recognition process, there is a time of about 5 seconds from the end of the time signal announcement to the transmission of the confirmed tone at that time.
It needs a processing capability that recognizes the time signal within seconds and completes the transmission to the counting means 3 and the first collating means 4. If this processing capacity cannot be obtained, the processing capacity is supplemented in three stages: hour, minute, and second. In recognition of the time confirmation tone,
The first collating means 4, the second collating means 5 and the counting means 3 recognize the confirmation of the time, convert the signal into a signal, and send it as a trigger for the collation and setting of the counter value. Since the present invention always recognizes, checks, and sets the time that is being updated, it is desirable to use a hardware logic with a stable processing delay. Almost the same time information is set, and the time information can be set in the system and used for system operation.

FIG. 2 is a block diagram showing an embodiment of the time information setting method according to the present invention. Referring to FIG. 2, the present method includes a time setting device 17 and an information processing system 19.

). When detecting the occurrence of the time setting trigger (S2), the operation control unit 18b instructs the line connection unit 11 to connect to the time signal service (S3). After the connection to the time signal service is completed, the tone / voice recognition unit 12 receives the time signal announcement and the time confirmation tone (S4), recognizes the time of the time signal announcement by voice (S5), and counts the recognized time by the counter circuit 13. (S6).

Next, the time confirmation tone is recognized (S7).
A signal is sent to the counter circuit 13 to start updating the time information of the counter circuit 13 (S8). The tone / voice recognition unit 12 recognizes the next time signal (S9), and sets time information in the collation unit 14 (S10). Then, the time information set in the matching unit 14 is compared with the time information updated by the counter circuit 13 (S11), and the result of the matching is notified to the operation control unit 18b.

If the collation results match, the information processing system 19 sets the time information that is set in the counter circuit 13 and continues to be updated in the time control unit 18a and uses it for operation (S12). On the other hand, if the collation results are inconsistent in S11, the operation control unit 18b issues a collation instruction again and causes collation to be performed a predetermined number of times (S13). . If the collation results still do not match, an alarm is output as a failure (S14).

9 is compared with the time information used in the operation of S9 (S2).
4).

In the case of a match in S24, the operation is continued with the time information of the system (S25), and in a case of no match in S23, a predetermined number of matching operations are performed (S2).
6) As a result, if no match is obtained, an alarm is output as a failure (S27). On the other hand, if there is no match in S24, the time information of the counter circuit 13 is set in the information processing system 19 (S28), but the time control unit 18a
If the number of times set to is equal to or more than the number specified by the operation control unit 18b, an alarm is output as a failure (S2).

Next, the control unit 2 on the information processing system 24 side
FIG. 6 shows an example in which a part of the operation control function is included in the time setting device 22 as the operation control auxiliary unit 20 in order to reduce the load of No. 3.

The operation control auxiliary unit 20 includes a line connection unit 11
Instructions to connect to and disconnect from the time signal service,
It collects the collation results from 4 and 15 and performs re-collation control. The operation control unit 23b of the information processing system 24 controls only the time setting start and the collation setting start of the operation control auxiliary unit 20 via the interface unit 21, and the operation control auxiliary unit 20 sets the time to the time control unit 23a. It sends out the time information, the matching result, etc.

The schedule control for time setting and collation trigger and the algorithm for re-collation are also performed by the operation control auxiliary unit 2.

[0034]

As described above, according to the present invention, the first effect is that the reliability of the time information set in the system is improved, whereby the system can be operated with incorrect time information. Can be prevented. The reason is that the reliability of the time information itself to be set is improved by providing the collation function in the middle of setting the time information in the system from the time signal service.

The second effect is that the system can set the time instantaneously and can cope with the immediacy in information processing. The reason is that, by holding time information equivalent to the reference time of the time signal service in the counter circuit, setting can be performed without connecting to the time signal service each time the time is set.

A third effect is that maintainability is improved by enabling detection of a failure. The reason is that the collation of the time information of the counter circuit and the collation of the time information of the system are performed, so that a failure can be found.
