DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an audio timepiece with a warning function that detects various situations around the timepiece and issues an appropriate warning.

Clocks that notify the time indicated by the clock by voice are well known, and with this type of clock, it is possible to tell the time only by hearing when the indicated time is difficult to read, such as at night or while working in a factory. It can also be widely used as a watch for the blind. Conventional audio timepieces employ voice writing/reading systems that utilize recent digital processing, and can provide excellent audio timekeeping using small electronic circuits.

The present invention provides an audio signal with a warning function that uses the audio time signal function of the audio time clock described above to detect various situations in the surroundings where the clock is installed, and that can issue a warning based on the detection signal by voice. It concerns a time signal clock.

According to the present invention, it is possible to give an audio warning of an indoor gas leak, a fire outbreak, a weather forecast, etc. It is difficult for the user to know the meaning of
According to the present invention, since the content of the warning is directly announced by voice, the user can quickly learn the surrounding situation.

Preferred embodiments of the present invention will be described below based on the drawings.

The figure shows a block diagram of an audio timepiece to which the warning method according to the present invention is applied.

A high-frequency signal from a reference signal generator 10 including a crystal oscillator is converted into a desired frequency-divided pulse train by a frequency dividing circuit 12, and the pulse train with a period of 1 second is supplied to a second counter 14. The second counter 14 is a sexagesimal counter and supplies minute pulses with a period of 60 seconds to the minute counter 16. The minute counter 16 also comprises a sexagesimal counter and supplies its output, the hour pulse, to an hour counter 18 comprising a decimal counter. This reference signal generator 10, frequency dividing circuit 12, second counter 1
4. The minute counter 16 and the hour counter 18 constitute a clock circuit 19 that clocks a reference signal to form a time signal.

Minute counter 1 is used to notify the specified time by voice.
6 and the count value of the hour counter 18 are supplied to the digital multiplexer 20, and at the same time, a code signal for reading out the sound "hun" or "ji" from the sound storage section to be described later is supplied to the digital multiplexer 20. and is supplied from the "di" code ROM 24.

The audio selection signal output from the digital multiplexer 20 is supplied to the audio notification circuit 28 via the 3-state buffer 26, and the audio signal corresponding to the designated time is supplied to the speaker 32 via the amplifier 30. Therefore, the designated time is announced from the speaker 32 using the audio selected by the digital multiplexer 20. In order to notify the time by voice, the present invention has an audio ROM 34 that stores the voice as digital data, and the audio ROM 34 contains time digits, ie, "zero" to "zero".
Numeric sounds up to "Kiyuu" and sounds "Hun" and "Ji" are stored, and based on the time code signal from the digital multiplexer 20, audio data corresponding to a desired designated time is selected. In this embodiment, the audio notification circuit 28 transfers audio data corresponding to the time code signal to the audio ROM 3.
This is a circuit that reads audio data from ROM 36 and broadcasts audio based on this audio data.

The start address and end address, which are time code signals from the ROM 36 and 38, are stored in both designated ROMs 36 and 38. The time code signals are stored in the order of the output signals from the digital multiplexer 20. For example, in the case of a designated time of "12:35",
The digital multiplexer 20 first stores the number in the 10th place of the hour counter 18, ie, "JIU", into the start address and end address designation ROMs 36 and 38 as a time code signal. designation
The start address of the ROM 36 is selected from the audio ROM 34 via the address counter 40, and the audio data is accessed and converted into an analog signal by the DA converter 44, and then passed through the low-pass filter 46. , unnecessary harmonic components are removed and output to the amplifier 30. The audio ROM 34 is accessed until the current address matches the end address, and for this purpose the current address is sequentially compared with the end address of the end addressing ROM 38 by the digital comparator 42. Then, when the current address and the end address match, that is, the reading of the audio data "JIYU" is completed, the process moves to the next audio data reading step.

In order to sequentially update and supply the time code signal from the digital multiplexer 20 to the audio notification circuit 28, the count signal from the heptadary counter 48 is supplied to the digital multiplexer 20. 7
When the advance counter 48 is reset, the signal from the counter 48 causes the digital multiplexer 2 to
0 selects the 10th signal of the hour counter 18. When the output of the 10th audio data is completed and the digital comparator 42 outputs a comparison output, the heptadary counter 48 counts +1 via the one-shot circuit 50, and as a result, the digital multiplexer 20 The voice notification circuit 2

Configure.

The aforementioned audio data is read out using the time signal switch 5.
This can be done at any time by performing step 2.
That is, the time signal switch 5 is connected to the AND gate 54.
A time signal is supplied from 2 at an arbitrary time, and the time signal trigger signal of the AND gate 54 is supplied to the one shot circuit 5.
6 to the reset terminal of the heptad counter 48, and from the flip-flop 60 via the OR gate 62 to open the AND gate 64. An address pulse is supplied from the frequency dividing circuit 12 to the other input terminal of the AND gate 64, and when the AND gate 64 is opened, the address pulse is supplied to the address counter 40 of the audio notification circuit 28, and the address pulse is supplied from the audio ROM 34 mentioned above. The audio data is read out. Therefore, the designated time is announced from the speaker 32 at any time when the time report switch 52 is operated. The time signal switch 52 and flip-flop 60 constitute a time signal trigger circuit 61 which outputs a time signal trigger signal for starting the operation of the time signal code generation circuit 57 and audio notification circuit 28.

As described above, in the audio time signal clock of the embodiment, the designated time is read out as an audio signal by operating the time signal switch 52, and the audio time signal section consisting of the speaker 32 reports the audio of the time. A feature of the present invention is that this audio time reporting function is used to issue audible warning sounds in response to detection signals from various sensors connected to the watch.

For this reason, this embodiment includes a sensor circuit 71 having multiple types of sensors that output detection signals when preset conditions are met, including a gas sensor 66 for detecting gas leaks, and a temperature sensor for detecting fire. 68 and includes a humidity sensor 70 for identifying rainy or sunny weather. and these 3
These three types of warning sounds are stored as digital audio data in the aforementioned audio ROM 34 corresponding to the type of sensor, and in order to read out these stored contents, the gas sensor code ROM 72, temperature sensor code ROM 74, and humidity sensor code are used. ROM7
6 is provided. Each code ROM72,7
4,76 codes are fed to a multiplexer 78, and these codes are sent to the three types of sensors 66,
68 and 70 selectively read out the code from the multiplexer 78, and the read code is supplied from the 3-state buffer 80 to the audio notification circuit 28. The code ROMs 72, 74, and 76 and the multiplexer 78 constitute a warning code generation circuit 79 that outputs a warning code signal that selects audio data corresponding to the detection signal from each sensor.

The detection signals of the sensors 66, 68, and 70 are supplied from an OR gate 82 to a set input of a flip-flop 86 via a one-shot circuit 84. The Q output of the flip-flop 86 supplies an operating signal to the three-state buffer 80, and is also applied as a signal to control the supply of address pulses from the OR gate 62 to the address counter 40 of the audio notification circuit 28 via the AND gate 64. . This OR gate 82, one shot circuit 8
4 and the flip-flop 86 constitute a warning trigger circuit 87 which outputs a warning trigger signal to operate the audio notification circuit 28 when any detection signal is output from the sensor circuit 71. , a code selection circuit 81 is configured to selectively output a time code signal to the audio notification circuit 28 when outputting a time signal trigger signal. The Q output of flip-flop 86 is supplied to the gate input of AND gate 54, and as a result, when any sensor 66, 68, 70 outputs a detection signal and sets flip-flop 86, AND gate 54 is closed and this It is prohibited to operate the time signal switch 52 to make an audio time signal. This AND gate 54 constitutes a gate circuit 55 that prohibits the output of the time signal trigger signal when the warning trigger signal is output.

In the above manner, one of the sensors 66, 6
When the detection signal is output from 8, 70, the 3-state buffer 80 and the audio notification circuit 28 become active, and at this time, one of the code ROMs 72, 74, 76 selected by the multiplexer 78 is activated.
A code signal is supplied from the three-state buffer 80 to the audio notification circuit 28, and audio data according to this code is read from the audio ROM 34. Therefore, the content of the warning detected by the sensor is announced as audio from the speaker 32, and the user can accurately know the surrounding situation. Since the gate circuit 55 does not output the time trigger signal from the time trigger circuit 61 during the period when the warning content is being announced, the designated time is not announced by voice.

As explained above, according to the present invention, when issuing a warning by voice using the voice notification function of the watch,
By disabling the audio notification function such as the designated time during the warning notification period, it is possible to prevent the warning notification from being interrupted due to erroneous operation of the time switch, etc., and to ensure that important warning contents are notified. Can be done.
