Abstract

PURPOSE:To provide a clock system capable of sharply correcting the error of the time and securing the high reliability of the time. CONSTITUTION:An automatic dial circuit 11 calls the time broadcasting service connected to a telephone line under the control of a control circuit 10, and a voice recognizing circuit 12 recognizes the voice of the time information of the time broadcasting service. A comparing circuit 13 compares the time of the voice-recognized time information with the time of a clock circuit 14. If both of them are inconsistent, the time of the clock circuit 14 is corrected to the voice-recognized time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece mechanism incorporated in a computer system or the like, and more particularly to a timepiece mechanism suitable for automatically correcting the time in a system requiring accurate time.

[0002]

2. Description of the Related Art A conventional apparatus is disclosed in Japanese Patent Laid-Open No. 62-21438.
As disclosed in Japanese Patent Laid-Open No. 7-75, the timepiece built in the facsimile is compared with various tones of the time signal service, and the error of the timepiece is corrected based on the result.

[0003]

In comparison of the above-mentioned various tones according to the above-mentioned prior art, it is impossible to cope with a large time delay due to an accident or a large error due to a time setting error. There was a problem that the time of day had to be accurate to some extent.

An object of the present invention is to provide a timepiece mechanism which enables a large time error correction and ensures high time reliability.

[0005]

The clock mechanism of the present invention is a means for calling a time signal service connected to a public line, and voice recognition of time information received from the time signal service via the public line. And a second means for comparing the time of the time information recognized by voice with the time of the clock circuit, and a second means for correcting the time of the clock circuit to the time of the time information when the two do not match as a result of the comparison. It is characterized by having the means of 3.

[0006]

According to the present invention, the time of the clock circuit is corrected on the basis of the time obtained by voice recognition of the time information received via the public line, so that a large error correction of the time becomes possible, High reliability of time can be secured.

[0007]

The present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a clock mechanism of a computer system of the present invention, and FIG. 2 is a block diagram of FIG.
3 is a block diagram showing details of a voice recognition circuit shown in FIG.

The clock mechanism of the computer system of the present embodiment shown in FIG. 1 includes a clock adapter 1 and a network control device (hereinafter,
(Referred to as NCU) 2). The timepiece adapter 1 shown in FIG. 1 is for automatically correcting a timepiece error, and includes a control circuit 10, an automatic dial circuit 11, a voice recognition circuit 12, a comparison circuit 13, a timepiece circuit 14, and a system bus B.
And is configured.

FIG. 3 is a block diagram showing the voice recognition circuit 12 shown in FIG.
A voice analysis circuit 16, a matching circuit 17, and a standard pattern storage circuit 18 are provided.

FIG. 3 is a flow chart showing the operation of the embodiment shown in FIGS. 1 and 2, and the operation of the embodiment will be described with reference to this flow chart. Control circuit 1 shown in FIG.
0 means at system startup and at a fixed time (eg midnight, once a day when the computer is idle),
Upon receiving a command from a host device (not shown) via the system bus B, the automatic time error correction is started. The automatic dial circuit 11 automatically dials, for example, the time signal service "117" of Nippon Telegraph and Telephone Corporation (registered trademark) (step S1). As a result, the NCU 2 connects the timepiece adapter 1 and the telephone line (step S2). When the voice and various tones of the time signal service are input to the voice recognition circuit 12 through the connection to the telephone line, the analog / digital conversion circuit 15 converts them from an analog signal to a digital signal. The voice analysis circuit 16 extracts the features of the voice and various tones from the converted digital signal, and the matching circuit 17 outputs the pattern registered in the standard pattern storage circuit 18 and the features of the voice output from the voice analysis circuit 16. And are recognized to recognize the voice (step S3). After the voice recognition is completed, the comparison circuit 13 compares the time when the voice is recognized with the time of the clock circuit 14 (step S4).
If there is no error as a result of the comparison, the fact is reported to the control circuit 10, and the control circuit 10 cuts off the reception of the time signal service,
The automatic correction of the error ends. If there is an error,
Under the control of the control circuit 10, the clock circuit 14 changes the time to the time at which voice recognition is performed (step S5). In consideration of the time required for the correction, this automatic correction has a method of starting the setting based on the signal one second before the set time tone and completing the setting after one second. Then, the voice recognition circuit 12 recognizes various tones again (after the second time, only various tones are recognized, step S3), and the comparison circuit 13 compares the time with the time of the clock circuit 14 (step S4). If so, the correction operation ends.

As described above, the error correction is repeated until the time recognized by the voice recognition circuit 12 and the time of the clock circuit 14 coincide with each other, so that the time is always an accurate value.

Further, in FIG. 2, the standard pattern storage circuit 18 generally stores a standard voice pattern of a person, but since it is fixed to the time signal service of Nippon Telegraph and Telephone Corporation (registered trademark), The pattern storage circuit 18 may store a pattern dedicated to the time signal service, or the voice type of the pattern may be limited to the voice used for the time signal service. By limiting the voice type of the pattern to the voice used for the time signal service, the recognition rate of the time signal can be increased and the time can be accurately adjusted by the clock mechanism.

[0014]

As described above, according to the present invention, it is possible to provide a timepiece mechanism capable of significantly correcting the time error and ensuring the high reliability of the time.
