Abstract

PURPOSE:To eliminate the need for artificial monitoring and correcting operating by collating time information generated by a time casting service device with time information transmitted periodically from the timer device of an electronic exchange and correcting the information when necessary. CONSTITUTION:A time counting circuit 22 generates time information on the basis of a standard frequency signal from a crystal oscillator 21 to transmit it to a sound piece editing circuit 23 at every specific period, and also sends a second tone generating signal and a hour casting tone generating signal to a second tone and hour casting tone generating circuit 24, so that the sound piece editing circuit 23, circuit 24, and a mixing circuit 26 generate a time casting message. A time receiving circuit 28, on the other hand, transmits the time information from the timer device 15 to a time collating circuit 29 and a time rewriting circuit 210. The time collating circuit 29 collates the time information generated by the time counting circuit 22 with the time information sent from the time receiving circuit 28 and outputs the collation result. Further, the time rewriting circuit 210 sets the time information sent from the time receiving circuit 28 in the circuit 22 on the basis of the collation result from the time collating circuit 29 or when an external correction command is inputted. The time counting circuit 22 generates time information on the basis of the time information set by the time rewriting circuit 210 as an initial value.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a time signal service system in an electronic exchange.

Automatic switchboards are widely used to provide time signal services that notify subscribers of the current time when they dial a special number.

It is desirable that the work for always accurately maintaining the time notified by this type of time signal service be automated as much as possible.

It is also desirable that the means for realizing such a time signal service be constructed as economically as possible.

[Conventional technology]

FIG. 3 is a diagram showing an example of a conventional time signal service system.

In FIG. 3, an automatic exchange 1 has a time signal service device 2.
The crystal oscillator 21 in the 0 time signal service device i, which is provided with the 0 time signal service device i, generates a highly stable standard frequency signal and transmits it to the time counter circuit 22. The frequency signals are counted and the notification time (
The time information indicating HH hours, MM minutes, 88 seconds) is displayed at a predetermined period (
For example, the signal is transmitted to the sound piece editing circuit 23 at intervals of 10 seconds, and the strange sound generation signal and the time signal generation signal are also transmitted to the strange sound/time signal generation circuit 24. The sound piece editing circuit 23 extracts the required sound piece from the sound piece memory 25 based on the time information transmitted from the time counting circuit 22, and extracts a required sound piece from the sound piece memory 25, and extracts a required sound piece from the sound piece memory 25, SS seconds") and transmits it to the mixing circuit 26. In addition, the strange sound/time signal generating circuit 24 is connected to the time counting circuit 22.
In synchronization with the strange sound generation signal transmitted from the time counting circuit 22, a strange sound is generated at 1 second intervals and transmitted to the mixing circuit 26, and in synchronization with the time signal generation signal transmitted from the time counting circuit 22, a time signal sound is generated. and is transmitted to the mixing circuit 26. The mixing circuit 26 edits a time signal message by combining the time signal notification text transmitted from the sound piece editing circuit 23 with the strange sound and time signal sound transmitted from the strange sound/time signal sound generation circuit 24, and outputs the message via the message output circuit 27. and is supplied to the talkie trunk 11 of the automatic exchange 1. The automatic exchange 1 connects the subscriber 12 who has dialed a special number for the time signal service to the talkie trunk 11 via the network 13, and allows the calling subscriber 12 to listen to the time signal message supplied from the time signal service device 2. .

When starting up the time signal service device 2, a maintenance person sets the initial value of time information in the time counting circuit 22, and manually synchronizes it with the standard time separately obtained by, for example, standard radio waves transmitted from a standard organization. Activate it.

Even after the start of operation, the maintenance person periodically checks the time notified by the time signal message with the standard time, and if an error of more than a predetermined value occurs, corrects the time information using the same procedure as described above.

[Problem to be Solved by the Invention 3] As is clear from the above explanation, in conventional time signal service systems, maintenance personnel manually monitored and corrected the time information generated by the time signal service device. This monitoring and correction work required skill, and sufficient accuracy could not always be obtained.

[Means for solving problems]

The present invention solves the above problems by the following means.

If the automatic exchange equipped with a time signal service device is an electronic exchange, etc., the central control device uses a high-precision clock device (hard clock) to calibrate the time information created by software for use in billing processing, etc. There are few cases where it is equipped with (no).

In the invention of the youngest brother 1, time information generated by a clock device included in such an electronic exchange is periodically transmitted to the time signal service device. The time signal service device compares the received time information with the time information created within itself, and outputs the result of the comparison. Further, the time signal service device corrects the time information created within itself to the time information transmitted from the electronic exchange based on the verification result or an external command.

In the second invention, the time signal service device edits the time signal message based on time information periodically transmitted from a clock device included in the electronic exchange.

[Effect]

That is, according to the invention of the youngest brother 1, the time information created by the time signal service device is checked against the time information periodically transmitted from the clock device of the electronic exchange and corrected as necessary, thereby eliminating artificial monitoring and No correction work is required.

Furthermore, according to the invention of the youngest brother 2, the time signal service device does not create time information within itself, but edits the time signal message based on the time information periodically transmitted from the clock device of the electronic exchange, which solves the problem described above. Not only do the points disappear, but
The economic efficiency of the time signal service device is also improved.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a time signal service system according to an embodiment of the invention of Woodbrush 16, and FIG. 2 is a diagram showing a time signal service system according to an embodiment of the invention of youngest brother 2. It should be noted that the same reference numerals indicate the same objects throughout the plan.

In FIGS. 1 and 2, the time signal service device 2 is attached to an electronic exchange 10. In FIG. The electronic exchange 10 is equipped with a highly accurate clock device 15 in order to calibrate a software clock built into the central controller 14 . The clock device 15 periodically transmits time information to the time signal service device 2.

In FIG. 1, the time signal service device 2 includes a time receiving circuit 28 that receives time information periodically transmitted from the clock device 15 included in the electronic exchange 10, and a time information generated by the time counting circuit 22. The time verification circuit 29 verifies the time information received by the time reception circuit 28, and the time information transmitted from the time reception circuit 28 based on the verification result output from the time verification circuit 29 or a command input from the outside. A time rewriting circuit 210 that corrects the time information created by the time counting circuit 22 is provided.

In FIG. 1, the time counting circuit 22 creates time information based on the standard frequency signal transmitted from the crystal oscillator 21, as in FIG.
At the same time, the strange sound generation signal and the time signal generation signal are transmitted to the sound piece editing circuit 23, the strange sound and time signal generation circuit 24, and the mixing circuit 26.
create a time signal message.

On the other hand, the one-time receiving circuit 28 transmits time information periodically transmitted from the clock device 15 to the time verification circuit 29 and the time rewriting circuit 210. The time verification circuit 29 1 verifies the time information created by the time counting circuit 22 and the time information transmitted from the time receiving circuit 28, and outputs the verification result. Further, the time rewriting circuit 210 sets the time information transmitted from the time receiving circuit 28 to the time counting circuit 22 based on the verification result output from the time verification circuit 29 or when a correction command is input from the outside. . From now on, time counting circuit 2
2 creates time information using the time information set by the time rewriting circuit 210 as an initial value.

As is clear from the above description, according to this embodiment, the time information created by the time counting circuit 22 in the time signal service device 2 is the time information periodically transmitted from the clock device 15 included in the electronic exchange 10. and amended as necessary.

On the other hand, in FIG. 2, the time signal service device 2 is not provided with a crystal oscillator 21 and a time counting circuit 22, but is a time receiving circuit that receives time information periodically transmitted from a clock device 15 included in the electronic exchange 10. Only 28 are provided.

In FIG. 2, the time receiving circuit 28 transmits time information periodically (for example, every 10 seconds) transmitted from the clock device 15 to the sound piece editing circuit 25. The sound piece editing circuit 25 edits the time signal notification text based on the time information transmitted from the time receiving circuit 28 and transmits it to the mixing circuit 26. Further, the strange sound/time signal sound generation circuit 23 generates strange sounds at 1 second intervals in synchronization with the strange sound generation signal transmitted from the clock device 15.
Further, a time signal sound is generated in synchronization with the time signal generation signal transmitted from the clock device 15 and is transmitted to the mixing circuit 26. The mixing circuit 26 compiles the time message as in FIG. 3 and supplies it to the talkie trunk 11 of the electronic exchange 10 via a message output circuit 27.

As is clear from the above description, according to the present embodiment, the sound piece editing circuit 23 can obtain the time information necessary for editing the time signal notification text, and the strange sound/time signal sound generation circuit 24 can generate the strange sound and the time signal sound. Since both the necessary strange sound generation signal and time signal sound generation signal are transmitted from the clock device 15, the time signal service device 2 includes a crystal oscillator 21 necessary to generate the time information, the strange sound generation signal, and the time signal sound generation signal. Also, the time counting circuit 22 becomes unnecessary, and the time signal service device 2 becomes economical.

It should be noted that the above-mentioned embodiment is merely an example of the wood brush 1 and the second invention, and for example, the configuration of the time signal service device 2 is not limited to that shown in the drawings, and many other modifications may be considered. However, the effects of the present invention remain the same in either case.
