The security device 40 can receive power through the vehicle power supply 45, so that the power state can be judged at the same time, and if the power is off or the power system has a problem, the message can be immediately sent.

Applying the above-mentioned vehicle security system, the disclosure also discloses the flow of each signal in the security system, as shown in the flow chart of FIG.

Beginning in step S501, the security device is set to be in a standby detection state to detect an intrusion event. The step then proceeds to S503 to determine whether an intrusion signal generated by one or more sensors is detected. That is, the signal that the suspected intrusion event touches the sensor, such as the door is opened in the set state, the window is broken, the electronic device is destroyed, the power is interrupted or abnormal, the car body is vibrated, the engine is abnormally started, and the battery is activated. Abnormal voltage, abnormal vehicle movement (monitoring through global positioning system), etc. If not, the step proceeds to S501, that is, when no intrusion possible signal is detected, in step S501, the security device is in the standby detection state.

If a suspected intrusion event is detected (Yes), in step S505, the security device will immediately activate the camera module to capture the image through the camera (step S507), and the camera module may be connected to one or more cameras, if multiple The camera can take images in multiple directions to avoid dead angles. The images captured by the cameras can be immediately transmitted to the control center (step S509), and the storage, file creation, and the instant detection of the illegal intruders or suspicious events can be determined. Then, in step S511, the relevant preservation measures are executed, and the preservation measures include confirming whether the intrusion behavior is true, and then sending the personnel, notifying the owner, and the like; if not, the entire security state is reset.

Afterwards, the images stored in the control center or the specific file server are accessible files, stored in the database, and provided by a user authentication and authorization program. For example, the owner can access the authorized download image of the system through the computer system through the network at any time after being authenticated by the user. In actual operation, the user sends an anti-theft authorization code from the control center to authorize the user to download.

In the flow depicted in FIG. 5, in an embodiment, when the intrusion signal is detected (step S503), the display device determines that there is an intrusion behavior, and the present invention further confirms whether the intrusion behavior is true through the image. Thereafter, in addition to starting the photographic module as in step S505, the positioning function of the vehicle can be simultaneously activated, that is, the vehicle position is obtained through the global positioning module in the security device, as in step S506, to immediately arrive at the vehicle position processing.

Moreover, in step S508 of FIG. 5, in addition to capturing the in-vehicle or out-of-vehicle image through the camera module, the voice module can be activated (such as 404 in FIG. 4), and the sound in the car can be received to assist in judging whether Intrusion behavior, and can communicate with the people in the car two-way communication, the personnel can be confirmed by the password, identity data, etc. as the person who can log in to use the vehicle, in order to confirm whether it is an intrusion event.

Therefore, when an abnormal intrusion signal is generated inside the vehicle, the control center personnel can confirm the event through the image, which can avoid false positives or misjudgment. In the case of intrusion, the location of the vehicle can be judged through global positioning data for tracking and fast-on-site processing, and the above-mentioned voice module provides two-way communication with the vehicle personnel.

Based on the above description, the in-vehicle security system described in the present disclosure mainly activates the camera to capture the inside of the vehicle when the intrusion detection unit receives the suspected intrusion or destruction signal, or may add an image outside the vehicle. In addition to instant judgment of intrusion behavior, it can also generate image files, providing users with instant viewing, downloading and other services to achieve vehicle preservation.

However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent structural changes that are made by using the specification and the contents of the present invention are equally included in the present invention. Within the scope, it is combined with Chen Ming.
