Description

The present invention senses a person with a human sensor at night or in the daytime, the garden lamp is lit at night, the lamp is not lit during the day, and a warning sound is emitted. It is related with the crime prevention system which can project suspicious person intrusion.

In recent years, there has been an increasing interest in crime prevention. In the current situation, so-called picking (inserting and unlocking a rod-like body through a keyhole) and theft of garden items occur frequently in the white as well as at night. These incidents tend to occur during daytime, at home or at night, after the family goes to bed.

In response to this, various measures have been taken, and applications for such measures are also seen. For example, as shown in Document 1, there is shown a warning facility that monitors the entire building with a monitoring camera, accumulates image information, and reports an image to a predetermined monitoring station.

Problems to be solved by the invention

However, since the monitoring device of Patent Document 1 continuously monitors even when no incident occurs, the information data capacity for image storage becomes full immediately, and many storage media need to be constantly replaced.
The present invention has been made in view of such circumstances, and provides a crime prevention system that automatically senses when a suspicious person enters, warns by voice, and captures and accumulates images only when necessary. Objective.

Means for solving the problem

In order to achieve the object, the invention according to claim 1 of the present invention is configured to transmit a human voice to an outdoor speaker using a human sensor, an outdoor speaker, an automatic sound generator, and / or an indoor microphone. When a person or animal invades, the human sensor can detect this, and the housekeeper in the room can know these intrusions. Can do.
Since the invention according to claim 2 further includes an outdoor monitoring camera, an indoor monitor, and a video recording device, the person or animal that has entered the site is observed indoors, and both video and audio are recorded. After the elapse of time, the contents can be confirmed and stored as evidence.
The invention according to claim 3 of the present application is provided with a length measuring means for judging the height dimension of the intruder and the invading animal, and the system is controlled so as not to operate below a certain size. Even if a so-called small animal invades, the system does not operate as an intruder, so that a warning voice is not issued at midnight, and a trouble that a family member determines that there is an intruder and jumps in at midnight can be avoided.
The invention according to claim 4 of the present application is to detect the temperature of the intruder and the invading animal only at a constant temperature in order to avoid detecting that the branch of the tree is shaken by the wind and the sensor malfunctions and suspicious. Since the system is configured to operate, the trouble can be prevented.
According to the fifth aspect of the present invention, even when the housekeeper is a deaf person, the housekeeper who has received the outgoing signal built in or attached to the indoor speaker wears the receiving device by vibration at the time of reception. It is possible to know outdoor abnormalities by attaching to.

The invention's effect

    According to the security system of the present invention, when a person enters the site at night, a human sensor can issue a warning to the person, and if necessary, an indoor householder issues a warning directly from a microphone through an outdoor speaker. It is possible to record sound and video at the same time, so it is possible to secure evidence. As in the daytime, it is possible to record images while the motion sensor is operating, so the number of recording media can be minimized. In addition, it does not react to small animals such as dogs and cats, and does not react to tree branches or the like that do not have a constant body temperature.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an overview of the system of the present invention. Reference numeral 1 is a human sensor, and 2 is a light.

This monolith is attached to a part of the house garden. At night, when a person enters the site and approaches a certain distance, the sensor 1 reacts and the light 2 lights up. When a person falls asleep at night, it is normal for an indoor housekeeper not to notice that the light has been lit, so at the same time as the light is lit, the house speaker 3 is informed by a buzzer sound that the light has been lit by the indoor speaker 3. . It is common for a suspicious person to escape when a suspicious householder goes to the microphone 5 via the controller 4 and shouts "Which is it" or "Thief!"

Here, it can be considered that a great effect can be obtained by automatically producing a sound such as “Which is it?” From the outdoor speaker 6 by a voice of a person recorded in advance when the light 2 is turned on by the reaction of the sensor 1. It is desirable that the audio content to be uttered can be selected from a plurality of types in advance as appropriate. In this case, that is, when the recorded voice is emitted, the family member does not need to wake up, but when it is still suspicious, it is more effective to take action such as to wake up and speak. For recording sound, a sound reproducing tape deck connected to the microphone 5 is used.

In this example, it is explained that the human voice is automatically uttered from the outdoor speaker 6 at the same time as the light 2 is turned on, but at the same time, the surveillance camera 7 turns the garden garden to a wide angle or takes a picture of the fixed position and displays the image on the indoor monitor. 8 may be projected. At the same time as the human sensor 1 is turned on, the switch of the controller 4 is turned on, the monitor 8 is turned on, the recording / playback device 9 such as a video deck or DVD is turned on, and automatic recording is started. These may be linked simultaneously with the human sensor 1ON, and it is possible to operate only one of the necessary devices as necessary. These combinations can be easily made by turning on and off the switches of the respective devices.

Since it is inconvenient if the light 2 is turned on only by passing a person outside the site, it is necessary to adjust the sensitivity of the sensor 1 in advance to avoid this. Needless to say, the sensor 1 can be set to operate only at a constant illuminance such as at night, and the human body infrared ray is detected even in the daytime regardless of the brightness, and the light 2 is not turned on. The outdoor speaker 6 emits a sound such as “Who is it?”, “Thief!” Or “Welcome”, and the surveillance camera 7 starts to shoot and automatically records outdoor sound and video on the recording device 9. It is also possible to make it possible. For example, when a housekeeper goes out in the daytime, if someone wants to enter the garden, or wants to know who came to the entrance after returning home, the motion sensor can be activated even during the day by playing the recording device 9 If set to, these operations are possible.

All of these are possible by turning on and off the switches of the respective devices.
When the garden is dark at night, the motion sensor 1 is activated but the light 2 is not turned on. The sound of the indoor speaker 3 in the house tells that a suspicious person has entered the monitor (TV) It is also possible to set so that the screen can be seen. In this case, it is possible to use an infrared night vision camera.

Since monitoring from different directions in the garden may be required, a plurality of sensors 1, lights 2, monitoring camera 7 and other sets may be installed at different positions. In this case, it is possible to install a plurality of monitors 8 'and recording devices 9', and it is possible to shoot and record different angles by switching the channel of one monitor. Normally, it would be rare for a suspicious person to enter from a plurality of locations at the same time. Therefore, it is appropriate to operate only a device in which a plurality of installed human sensors 1 are turned on. In the unlikely event of multiple intrusions at the same time, even with one monitor 8 recording device, one screen is displayed for a certain period of time, and then another screen is displayed. Since devices that project the screen exist as products, they can be realized by using them.

An embodiment in which the present system can be used even when the householder is a deaf person or a blind person will be described. In the case of a hearing-impaired person, the sound from the indoor speaker 3 cannot be heard. Therefore, when the hearing-impaired person goes to bed, a signal is received from a signal transmission device (not shown) that is built in or attached to the indoor speaker 3. Like a silent vibration incoming call from a mobile phone, it is possible to know an outdoor abnormality by wearing a small receiver. This signal may be either a wireless incoming call or a wired call.
It is also effective to add a function of visually informing signal reception when the small receiver emits light.
In addition, since it is common for a blind person to hear the ear, it can be detected by the sound of the indoor speaker 3 and can be dealt with by calling another person.
In addition, although the signal transmission apparatus was demonstrated as what is built in or attached to the indoor speaker 3, it cannot be overemphasized that it is good also as an apparatus which can transmit a signal from an independent apparatus.

There is a problem to be noted here. For example, even if a dog or cat enters the site at night, the animals may be detected, the light 2 is turned on, and the system may operate as if a suspicious person has entered, as described above. A recent high-sensitivity sensor has caused this problem in reality, and a problem has arisen in which a family member sleeping late at night is surprised. Therefore, in order to prevent this in the present invention, the size of the dog or cat is detected, and when it is determined that the person is not a person from the size, the setting is made so that the system does not operate.

The outline is as follows. In other words, length measurement sensors are installed at the entrance of the site, the upper part of the fence. When it is determined by the length measurement sensor that the object such as a dog or cat is 60 cm or less, for example, the system is not operated.

A specific description will be given based on FIG. For example, a cat that has entered the site through the gap between the gates 10 is measured in the height direction by length measuring sensors 11a and 11b. If this is, for example, 45 cm, it is determined that the person is not human and the system is not operated. A length measuring sensor 13 is also installed in the upper part of the block rod 12, and the same determination is made. Here, the length measuring sensors 11 and 13 are composed of infrared beam projection units 11a and 13a embedded in the vertical direction in the form of dots and light receiving units 11b and 13b corresponding to the infrared beam projection units 11a and 13a, respectively. It is a device that measures the thickness. It is more effective to use invisible light that is not visible to dogs, cats, and people as well as infrared light.

Another problem is that the branches of a strong windy day tree or garden tree shake and are judged to be large in size, and the human sensor 1 malfunctions, and the system operates as if it is determined that a suspicious person has entered. There was from the applicant's experience.
In order to prevent this, the system was configured so that the length measurement sensor judged that the size of the object was large and the body temperature was above a certain level.
By juxtaposing the temperature sensors 14 and 15 in the vicinity of the length measuring sensor, it is possible to determine that the sensor is not a living thing or a person by using both sensors, and more safety and security can be obtained.
As described above, the length measuring sensor has been described by the invisible light projection light receiving method, but the length can be measured by another method. The embodiment will be described.

For example, as shown in FIG. 3, during shooting with the camera 16, for example, a dog 19 passing through the gate 20 is imaged, and the height direction thereof is compared with a dimension measured in advance to know the height direction dimension of the dog 19. is there. In this case, an error occurs in the dimension in the height direction when the dog 19 approaches the left or right side of the gate 20, but the size of the dog and cat can be improved by installing the camera 16 in the right direction from the position shown in FIG. 3. In practical use, there is no problem in error and it can be used effectively.
