And a control unit (for example, a central processing unit (CPU)) 5. The controller 5 is connected to a timer circuit 6 that measures a certain time.
[0021]
The vibration detection sensor 1 is attached to each part of the vehicle body such as a bonnet, a fender, a roof, a trunk, a bumper, a door, a tire wheel, and other components around the chassis and the engine.
[0022]
As the human body detection sensor 2, a human body detection sensor that has been conventionally used can be used. For example, a human body detection sensor using infrared rays or a human body detection sensor using ultrasonic waves can be used. . The installation location of the human body detection sensor 2 may be a vehicle body, a vehicle or the like (for example, a garage wall), or both the vehicle and the vehicle. The number of human body detection sensors 2 to be installed may be appropriately determined depending on the balance between the shape and size of the vehicle to be installed and the detectable range of the human body detection sensor 2. That is, the installation location and the number of installation of the human body detection sensor 2 may be appropriately adjusted so that a person approaching a predetermined distance to the front and rear, the left and right, and the upper and lower peripheral portions of a vehicle or the like can be reliably detected.
[0023]
As the camera device 3, a digital camera, a digital video camera, or the like can be used. The camera device 3 may be installed at the vehicle body, around the vehicle (for example, a garage wall), or both around the vehicle body and the vehicle. Further, the number of camera devices 3 to be installed may be determined as appropriate according to the balance between the shape and size of the vehicle to be installed and the shootable range of the camera device 3.
[0024]
The transmission circuit 4 may output an optical signal or a radio signal such as a radio wave as a theft detection signal to the alarm notification device, and outputs a theft detection signal or a photographed image to the alarm notification device through a signal line. It may be.
[0025]
Note that the alarm notification device is preferably installed in a place where a person is always waiting (for example, a security room) in order to output a captured image.
[0026]
Next, an embodiment of the theft detection device will be described with reference to the drawings.
[0027]
[ Reference Example 1]
FIG. 2 is a flowchart showing a processing operation corresponding to the reference example 1 of the theft detection device shown in FIG .
[0028]
When the user parks the vehicle or the like, the user operates the theft detection device and leaves the vehicle or the like.
[0029]
Thereby, the theft detection device is in a state where the vibration detection sensor 1 always detects the vibration of the vehicle body (step S1).
[0030]
In this state, when vibration is detected by the vibration detection sensor 1 (Yes in Step S1), the vibration detection sensor 1 outputs a vibration detection signal to the control unit 5 (Step S2). ). When receiving the vibration detection signal, the control unit 5 operates the camera device 3 to start photographing around the vehicle or the like (step S3).
[0031]
In addition, when receiving the vibration detection signal, the control unit 5 outputs a predetermined signal to the transmission circuit 4, and the transmission circuit 4 outputs a theft detection signal to an alarm notification device (not shown) (step S4). Accordingly, the alarm notification device outputs an alarm sound. Further, the control unit 5 compresses a photographed image of the surroundings of the vehicle or the like photographed by the camera device 3 by a predetermined compression technique (JPEG, MPEG, etc.), and outputs this to the transmission circuit 4 to the alarm notification device. A captured image is output (step S4). In the alarm notification device, the photographed image sent after being compressed is decoded and displayed as a photographed image on a display unit (not shown) or printed out from the printing device.
[0032]
As described above, according to the theft detection device of the first reference example, when a suspicious person tries to open a door of a parked vehicle or the like, the vibration detection sensor 1 detects this and detects the vibration. Based on the signal, a photographed image around the vehicle or the like photographed by the camera device 3 is transmitted from the transmission circuit 4 to the alarm notification device. As a result, a photographed image of a suspicious person can be obtained, and even if the suspicious person has already escaped when the owner of the vehicle rushed to the place, the suspicious person is identified from the photographed image. You can report to the police. In addition, since a theft detection signal is also sent to the alarm notification device, the owner of the vehicle or the like can know in real time that his / her vehicle or the like is stolen by the alarm based on the theft detection signal. it can. As a result, it is possible to take a quick response such as reporting to the police.
[0033]
Reference Example 2 FIG. 3 is a flowchart showing the processing operation corresponding to Reference Example 2 of the theft detection device shown in FIG .
[0034]
When the user parks the vehicle or the like, the user operates the theft detection device and leaves the vehicle or the like.
[0035]
Accordingly, the theft detection device is in a state of detecting this when the suspicious person approaches the vehicle or the like by the human body detection sensor 2 (step S11).
[0036]
In this state, when the human body detection sensor 2 detects that a suspicious person has approached the vehicle or the like (when it is determined Yes in step S11), the human body detection sensor 2 detects the human body with respect to the control unit 5. A detection signal is output (step S12). When receiving the human body detection signal, the control unit 5 operates the camera device 3 to start photographing around the vehicle or the like (step S13).
[0037]
In addition, when receiving the human body detection signal, the control unit 5 outputs a predetermined signal to the transmission circuit 4, and the transmission circuit 4 outputs a theft detection signal to an alarm notification device (not shown) (step S14). Accordingly, the alarm notification device outputs an alarm sound. Moreover, the control part 5 compresses the picked-up image around the vehicle etc. image | photographed with the camera apparatus 3 with a predetermined | prescribed compression technique, outputs this to the transmission circuit 4, and outputs a picked-up image to an alarm alerting | reporting apparatus ( Step S14). In the alarm notification device, the photographed image sent after being compressed is decoded and displayed as a photographed image on a display unit (not shown) or printed out from the printing device.
[0038]
Thus, according to the theft detection device of the present reference example 2, when a suspicious person approaches a parked vehicle or the like, the human body detection sensor 2 detects this, and based on the human body detection signal, the camera device 3 is transmitted from the transmission circuit 4 to the alarm notification device. As a result, a photographed image of a suspicious person can be obtained, and even if the suspicious person has already escaped when the owner of the vehicle rushed to the place, the suspicious person is identified from the photographed image. You can report to the police. In addition, since a theft detection signal is also sent to the alarm notification device, the owner of the vehicle or the like can know in real time that his / her vehicle or the like is stolen by the alarm based on the theft detection signal. it can. As a result, it is possible to take a quick response such as reporting to the police.
[0039]
[Example 1 ]
FIG. 4 is a flowchart showing a processing operation corresponding to the first embodiment of the theft detection apparatus shown in FIG .
[0040]
When the user parks the vehicle or the like, the user operates the theft detection device and leaves the vehicle or the like.
[0041]
Thus, the theft detection device detects a case where a suspicious person approaches the vehicle or the like by the human body detection sensor 2 and always detects vibration of the vehicle body by the vibration detection sensor 1 (step S21).
[0042]
In this state, first, when the human body detection sensor 2 detects that a suspicious person approaches the vehicle or the like (when it is determined Yes in step S21), the human body detection sensor 2 The human body detection signal is output (step S22). When receiving the human body detection signal, the control unit 5 operates the camera device 3 to start photographing around the vehicle or the like (step S23).
[0043]
In addition, when receiving the human body detection signal, the control unit 5 activates the timer circuit 6 and starts measuring a certain time (for example, 10 seconds) (step S24). When vibration is detected by the vibration detection sensor 1 during the measurement for a certain time (when it is determined Yes in step S25), the vibration detection sensor 1 outputs a vibration detection signal to the control unit 5. (Step S26). When receiving the vibration detection signal, the control unit 5 compresses a photographed image of the surroundings of the vehicle or the like photographed by the camera device 3 by a predetermined compression technique, outputs the compressed image to the transmission circuit 4, and based on the vibration detection signal. A predetermined signal is output to the transmission circuit 4. Based on the predetermined signal, the transmission circuit 4 outputs a theft detection signal to the alarm notification device and outputs a captured image to the alarm notification device (step S27). Thus, the alarm notification device outputs an alarm sound, decodes the captured image sent after being compressed, displays it as a captured image on a display unit (not shown), or prints it out from the printing device.
[0044]
On the other hand, if vibration is not detected by the vibration detection sensor 1 in step S24 even if a certain time is measured (if it is determined Yes in step S24), for example, the passerby can simply approach the vehicle or the like. In step S28, the captured image is erased (step S28), the timer circuit 6 is reset (step S29), and the process returns to step S21.
[0045]
As described above, according to the theft detection apparatus of the first embodiment, when the vehicle is not intended for theft such as a vehicle, the captured image is transmitted only when the vehicle is used for theft. Thus, it is possible to avoid erroneous detection such that a mere passerby is determined to be a suspicious person. In addition, when a suspicious person approaches a parked vehicle, the captured image of the suspicious person can be obtained, so when the owner of the vehicle rushes to the place, the suspicious person has already escaped. Even in the case of suspicion, the suspicious person can be identified from the photographed image and reported to the police or the like. Furthermore, since a theft detection signal is also sent to the alarm notification device, the owner of the vehicle or the like can know in real time that his / her vehicle or the like is stolen by the alarm based on the theft detection signal. it can. As a result, it is possible to take a quick response such as reporting to the police.
[0050]
According to the theft detection device of the present invention, when a suspicious person approaches a parked vehicle or the like and tries to open the door of the vehicle or the like, the image is taken by a digital camera or digital video camera as a photographing means. The captured image around the vehicle or the like is transmitted from the transmission means. As a result, a photographed image of a suspicious person can be obtained, and even if the suspicious person has already escaped when the owner of the vehicle rushed to the place, the suspicious person is identified from the photographed image. You can report to the police. Further, based on the human body detection signal output from the human body detection means, the photographing means starts photographing around the vehicle and the like, and based on the vibration detection signal output from the vibration detection means, the captured image is transmitted from the transmission means. It is configured to do. In other words, for example, if the vehicle is just close to the vehicle, etc., and it has passed as it is, that is, if it is not the purpose of stealing the vehicle, etc. Since the photographed image is transmitted, it is possible to avoid an erroneous determination that a mere passerby is determined to be a suspicious person. Further, since the transmission means is configured to output the theft detection signal based on the vibration detection signal output from the vibration detection means or the human body detection signal output from the human body detection means, the owner of the vehicle or the like The alarm based on the detection signal allows the user to know in real time that his / her vehicle or the like is stolen and to confirm the behavior of the suspicious person. As a result, it is possible to take a quick response such as reporting to the police.
