Description

[Detailed Description of the Invention] The present invention relates to a voice watch with a security function that can be used as a crime prevention device.

According to conventional audio clocks, the measured time is outputted audibly in response to instructions such as key operations by the user. According to such a voice clock, there was no purpose other than to keep it in a certain place as an accessory.

In addition to accessories, there are also items that have game functions added so that they can be used as games, or items that have computer functions added.

However, in the past, there was no audio clock device that could be used for crime prevention purposes.

Therefore, the purpose of the present invention is to provide an audio clock that can be used for crime prevention, functions accurately as a crime prevention device during a certain time period, and functions as an audio notification clock during other times. be.

The present invention will be explained in detail based on the figures below. Fig. 1 shows an external view of the audio watch with security function according to the present invention, in which A is the watch body, S is the speaker, D is the digital display section, and K is the main body of the watch. is a key input section such as a time notification key and a time setting key, and M is a microphone for sound detection.

FIG. 2 shows a block diagram of the audio clock.
CPU indicates a central processing unit, which is connected to the crystal oscillator The time measurement information is appropriately supplied to a voice synthesizer (speech synthesizer) VS for audio output in order to output audio at each time.

Also, the generated sound (abnormal sound) captured by the microphone MIC is introduced into the CPU via the power amplifier AMP1 and the interface I/F, and the CPU
When the generated sound captured by the microphone MIC is transmitted during a preset time period (midnight), the voice synthesizer is first used to notify the current time.
Supply timing information to VS. Then, this timing information is sent to the power amplifier AMP2 and notified by the speaker SP, and if the next sound is not captured by the microphone MIC within a certain period of time, the voice synthesizer VS is sent with alarm information (for example, "``Thieves'').

Figure 3 is a flowchart showing the operation of the audio clock, which will be explained in a little more detail.
In step A1, time pulses are counted and the time is displayed based on the count. Next step J
In step 1, it is determined whether the current time enters a preset time zone (midnight) in a certain period, that is, whether the relationship is 6 o'clock < current time < 23 o'clock, and if the current time satisfies this relationship. If it is, that is, it is not night, the process proceeds to step J4, where it is determined whether or not there is a request for time notification using the key KEY. If the determination is "no", the process immediately returns to step A1, and if the determination is "yes", the process proceeds to step A2, where the current time is announced as ``what hour and minute it is now'', and then the process returns to step A1.

On the other hand, if it is determined in step J1 that the current time belongs to a preset time zone (midnight), the process proceeds to step J2. In step J2, it is determined whether the generated sound is captured by the microphone MIC,
If "no", the process returns to step A1, and if a sound is generated, step A3 is executed to notify the current time as "what hour and minute is it now?" Further step A after notification
4. Proceed to step J3, and if the sound is generated again within a certain period of time after notifying the current time, proceed to step A1.
If there is no generated sound again, the process proceeds to the next step A5 and an alarm ("thieves") is repeatedly issued.

In particular, the reason why the time was announced when the first sound was heard, and an alarm ("thieves") was given if there was no sound within a certain period of time after the notification was made was because of the intruder's psychological situation. This method makes use of a person's behavior, and based on this, it is possible to almost accurately determine whether or not the person is an intruder. In other words, the intruder's psychology is that if you suddenly announce the time etc. by voice, he will judge that the person in the house is still awake or not home, and will not act in a way that will cause further footsteps or noises. It is thought that it will not cause On the other hand, it would be unnatural for a person in that household to act in a way that does not make abnormal noises, even if a voice notification is made during that time period, and would probably make footsteps or other noises. Therefore, if there is no abnormal sound after a certain period of time has elapsed since the time notification, it is believed that it is possible to accurately determine whether the person is a person in the house or an intruder.

In this way, in addition to the audio time notification, it is possible to detect an intruder and issue an alarm ("thieves"). Note that it is more effective if the configuration is such that the alarm cannot be reset easily. Alternatively, a voice recognition function may be provided to determine whether or not there is an intruder based on a password.

As described above, according to the audio clock with security function of the present invention, by notifying the time by voice based on the detection of abnormal sounds, it takes advantage of the fact that the next action is different depending on whether the intruder is the intruder or the person in the house. The system determines whether or not there is an intruder, and if it determines that there is an intruder, it issues an alarm, so it not only functions as an audio time alarm, but also serves as a crime prevention device to determine whether the sound is an intruder or something else. and make it function without error.

Furthermore, since most of the crime prevention functions effectively utilize the voice synthesis function, special hardware for this purpose is extremely small, and therefore, it can be provided at a very low cost.
