Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle theft or harm prevention device for preventing automobiles, motorcycles, etc. from being stolen or harmed.

[Conventional technology]

As a theft or harm prevention device for this type of vehicle, if it detects that the vehicle door is forcibly opened or the vehicle vibrates abnormally while it is parked, the control device is activated based on the detected signal. There are some devices that are configured to emit a sound to remind people to leave that is stored in advance in a built-in IC memory, or to sound an alarm buzzer (references not listed).

[Problem to be solved by the invention]

In the case of a theft or harm prevention device that emits a sound to remind the person to leave, it can have a higher psychological deterrent effect on criminals than a warning buzzer. However, with conventional products, the same evocative voice is emitted repeatedly until the end after purchase, so if the thief is a habitual thief, it is possible that the thief has heard the same voice before and is used to it. However, a very high effect could not be expected.

Furthermore, even the same evocative voice can have different effects depending on the situation; for example, depending on the region, it may be more effective to use a dialect for the evocative voice. However, conventional anti-theft devices cannot effectively respond to the situation on the spot.

The present invention has been made to eliminate such inconveniences, and its purpose is to make it possible to emit a sound suitable for urging people to leave depending on the situation.

[Means to solve the problem]

In order to achieve the above object, the present invention is characterized by the following points.

In the first invention, there is provided a detection means for preventing theft or harm, a voice generation means for emitting a voice to remind people to leave, and a control means for operating the voice generation means based on detection information of the detection means. , the voice generating means is characterized in that the voice for evoking can be freely changed and set.

The second aspect of the present invention is characterized in that the voice producing means is comprised of a storage means that can be updated and recorded, and a voice reproduction means that reproduces the voice based on the information in the storage means.

In the third invention, the voice generating means includes a storage means for storing a plurality of types of evocative sounds, a selection means for selecting one of the plurality of stored evocative sounds. The present invention is characterized in that it comprises a sound reproduction means for reproducing the evocative sound based on the information in the storage means.

A fourth invention is characterized in that the detection means is configured to sense vibrations of the vehicle body.

[For production]

In the first invention, when an abnormality is detected by the detection means, the control device operates the voice generation means based on the information and emits a voice to remind people to leave, and the voice can be freely changed and set. You will be able to do this.

In the second aspect of the invention, even if the previous sound is stored in the storage means, the sound generation means can update and record a new sound, and the sound reproduction means can reproduce the new sound.

In the third invention, in the voice generating means, a plurality of types of evocative sounds are stored in the storage means, one of them is selected by the selection means, and the selected evocative sound is based on the information in the storage means. Then, the audio reproducing means starts reproducing the audio.

In the fourth aspect of the invention, the detection means detects as vibrations of the vehicle body when the vehicle door is forcibly opened or vehicle accessories are stolen while the vehicle is parked. This becomes information for control.

[Effects of the Invention] According to the first invention, the setting of the sound for reminding people to leave can be freely changed to different sounds (including not only vocal cords but also sounds with different meanings), so that the sound can be changed depending on the situation. Depending on the situation, the most effective arousal sound can be emitted. For example, in rural areas, it is possible to more effectively encourage people to leave by making sounds in a dialect. In addition, even criminals who are habitual thefts have difficulty getting used to the different voices, and the psychological deterrent effect can be maintained.

According to the second invention, so-called recording and playback becomes possible. It is economical because different voices can be emitted without increasing the capacity of the storage means or replacing the storage means. In addition, since it is possible to freely memorize sounds that are suitable for the current situation, it is versatile and versatile.

According to the third aspect of the invention, one is selected from a plurality of pre-stored types of evocative sounds to be emitted, so there is no need to memorize evocative sounds suitable for each occasion. Therefore, even in a hurry, it is possible to immediately emit a voice that is suitable for the current situation. It is also very convenient for people with language disabilities.

According to the fourth invention, although the vibration sensor serving as the detection means is easy to install and relatively inexpensive, it can reliably detect theft or harm of the vehicle. The reliability of the prevention device can be increased.

If it is ON, the stored audio will be played and the REC/
The PB display diode (LE1) 2) is turned on (step 7). If the PB switch (SW4) is OFF, the process proceeds to the next step without reproducing the audio.

When the above steps are completed, the device enters a standby state (step 6). The standby state is a state in which only audio storage and playback is possible, signals from the vibration sensor (SE1) and reed switch (SF3) are ignored, and the amplifier (6) is not operating. Then, when the set switch (SW6) is operated and turned ON in the standby state, or it is turned ON by the remote control circuit (4) (step 7), the vibration sensor (SEI) is maintained in the standby state for 15 seconds. )
The monitor starts waiting for input from the reed switch (SF3) and amplifier (6). 15 on standby
The 5 TBY display diode (LED3) lights up for a second (step 8). Incidentally, the anti-theft device does not operate during this 15 seconds, which is a grace period for the person to get out of the passenger car.

Once the above steps are completed, reed switch (SF3)
) is ON or OFF (step 9),
The presence or absence of a signal from the vibration sensor (SE1) is checked (step 10). If the reed switch (SF3) is ON in step 9, the alarm is sounded continuously (step 11), and then the process returns to step 8. Further, when a signal from the vibration sensor (SE1) is detected in step 10, the stored audio data is reproduced only once, and an alarm is sounded for 7 seconds starting from 3 seconds later.

Further, while the alarm is sounding, the alarm display diode (LED1) is turned on (step 12).

In addition, the reed switch (SF3) and vibration sensor (SE
Detection l) is performed in parallel.

[Another example]

In the above embodiment, a rewritable RAM is used as the memory (M), but it is also possible to use a ROM in which audio data is stored in advance, and to play back the audio data stored in these ROMs. . In this case, it is also possible to configure the memory (M) with multiple ROMs, store different audio data in each ROM, and select one of the audio data by pressing a button. .

By the way, the different voice data refers to various words that are effective in urging people to leave, such as "Someone please come,""Pleasestop,""Helpme,""Thieves,""I'm important to you." Please do not take it with you as it is a dangerous car.'' However, even though words have the same meaning, there are differences in mother tongues such as English and Japanese, regional differences such as Kanto and Kansai, differences in men and women, age differences in adults and children, honorific and profanity, and commands and requests. Although there are grammatical differences, these differences in expression and vocal cords are also treated as different audio data.

Therefore, in the case of a passenger car that travels around various regions, it is recommended to prepare a ROM that stores the voice for evocation in each region's dialect.
You can switch to the local dialect wherever you go, and if the owner is a woman, you can warn with a male voice if you prepare a ROM that stores audio data of a low male voice. . Also, even if the owner is a foreigner,
Since a warning can be issued in Japanese, theft prevention can be made more effective.

In addition, the main purpose of this anti-theft device is to prevent the passenger car, its equipment, or valuables inside the car from being stolen, but it can also be used in various other ways depending on the user's needs. It can be used for various purposes. For example, at a new or used car dealership, the selling points of the passenger car can be promoted to customers who open the door. Further, when a stranger borrows the vehicle with permission from the owner of the vehicle, the owner can also convey business or messages to the renter.

In the embodiments described above, the present invention is explained using a passenger car as an example of a vehicle, but it is also possible to apply the present invention to other vehicles such as a hand truck, a transport vehicle, a construction work vehicle, etc.

Furthermore, when the detection means detects an abnormality, not only an alarm or sound but also the headlights of the vehicle may be turned on. As a storage means, a tape recorder or a CD player may be used instead of an IC memory. As the detection means, in addition to the vibration sensor (SEL), a photo sensor, an ultrasonic sensor, or a touch sensor may be used.
