Abstract

PURPOSE:To calibrate time automatically without the intervention of an operator by calling a time-casting oscillation station through a public telephone circuit at set time, and calibrating the time of the timer device incorporated in an information processor. CONSTITUTION:When the incorporated timer device 3 indicates set time, the CPU2 of the information processor 1 calls the time-casting oscillation station from an automatic public telephone circuit calling device 6 and its acoustic signal is transmitted to a recognizing device 7. This device 7 confirms a sound from the time-casting station by the coincidence with a registered sound and supplies a corresponding code signal to the CPU2. Then, the stopping of the device 3 and its restart at correct time are controlled through the CPU2 to calibrate the time of the timer device incorporated in the information processor automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a time calibration method for an information processing device incorporating a clock device.

Generally, an information processing device having an internal clock device needs to calibrate the time of the clock device. In this case, the time was calibrated by the operator of the device listening to a time signal over the phone and resetting or setting the clock, which required time for the operator to calibrate, and caused errors due to incorrect operation. I got the drawback.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic time calibration method that can automatically calibrate the time of a clock device built into an information processing device without any operation by an operator.

The automatic time calibration system of the present invention has a configuration including: (1) an information processing device with a built-in clock device, and when the clock device reaches a preset time, the clock device calls a time signal transmitting station to a public telephone line, and the clock transmits a call from the time signal transmitting station. an automatic line calling device that receives the signal; and when this automatic line calling device receives the audio signal from the time signal transmitting station, it compares this audio signal with a predetermined first audio signal and recognizes these signals. a voice recognition device which, when recognizing a match, transmits the coincidence to the clock device via the information processing device; When a third predetermined sound signal is received from the time signal transmitting station, the time measurement is temporarily stopped and a predetermined time is set, and the time measurement is started from the time setting value when a third predetermined sound signal is received from the time signal transmitting station.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. This embodiment includes an information processing device 1 having a built-in clock device 3, an automatic calling device 6 for a public telephone line connected to the information processing device 1 via a connection line 4, and an information processing device 1 and a connection line 5. A connection line between the sound recognition device 7 connected via the public line automatic calling device 6 and a signal line 8 that transmits an acoustic signal from the public line automatic calling device 6 to the p1 sound recognition device and a public telephone line connected to the automatic calling device 6. 9. Note that the timepiece device 3 is composed of an electrically controllable circuit driven by a crystal oscillator.

When the time indicated by the clock device 3 reaches a predetermined time, the processing section 2 of the information processing device 1 gives an instruction to call the time signal transmitting station to the public telephone line automatic calling device 6 via the connection line 4. After the time signal transmitting station is called, the public telephone line automatic calling device 6 supplies the acoustic signal to the voice recognition device 7 via the signal line 8. This voice recognition device 7 has a word string that foretells a time signal (for example, "12
We will inform you of the hour 0 minutes 0 seconds. '') and time signal oscillation sounds (for example, 440Hz 3 seconds ago, 2 seconds ago, 8 seconds ago at the current time)
80Hz), and when those acoustic signals are transmitted through the signal line 8, the connection line 5 notifies the processing section 2 of the information processing device that the acoustic signal has been recognized. When the processing unit 2 of this information processing device is informed of the recognition of the time signal by the voice recognition device 7, it sets the time to the clock device 3 via the connection line 10.

Next, as a specific example, a case will be described in which time signal station number 117 is called once a day at 5:00 AM and 0 seconds to calibrate the time.

First, when the clock device 3 indicates 4:59:00 a.m., the processing unit 2 of the information processing device automatically calls the public telephone line and instructs the device 6 to call 117. At the same time, the voice recognition device 7 is brought into a recognition enabled state. This voice recognition device 7 has a telephone voice and 440Hz oscillation sound that says "I'm home, I'd like to inform you that it's 5:00 a.m."
, 880Hz is registered, the speech recognition device 7 in this recognition possible state sequentially encodes and reports the recognition results for the input audio signal to the processing unit 2 of the information processing device. The processing unit 2 of this information processing device stops the clock device 3 and sets the time when it receives the sign ``We are here to notify you of 5:00 a.m. 0 minutes θ seconds''. This set time is set to a preset value (5:00:00) taking into account the delay in the recognition time of voice recognition. Next, from the voice recognition device 7, 440Hz 3 seconds ago, 440H 2 seconds ago
z Recognition 5 - After the 880 Hz certification report is submitted, an instruction is given to the clock device 3 to start timing. This time setting can be done instantaneously because the clock device 3 is composed of an electrical logic circuit, a counting circuit, and the like.

As explained above, according to the present invention, the time can be automatically calibrated without the need for the operator to calibrate the time once a day. This is unnecessary and no problems will occur due to incorrect operation.
