Description

A vehicle anti-theft system

technical field

The utility model relates to the field of automobile anti-theft systems.

Background technique

Currently popular vehicle anti-theft systems on the market mainly include mechanical locks, electronic locks and GPS anti-theft devices. Although these anti-theft measures can delay the time of stealing, they all have certain limitations. Because the mechanical lock cannot alarm, the stability of the electronic lock is not good, the sensor misjudgment rate is high, and there is a risk of disturbing the people. After continuous development, the existing GPS anti-theft device has now realized positioning, sound and light alarm, mobile terminal monitoring, video shooting, and text messages. Functions such as notifying mobile terminals and connecting to car starting systems, but there are still many problems. For example, the installation of displays in some will lead to the possibility of exposure, which is easy to be damaged by thieves. The battery will cause the battery to lose power after the car is not used for a long time, and the vehicle cannot be started. Some communication networks are not stable enough, the data transmission capability is weak, and some modules have more modules with low integration, and the cost will also increase. Moreover, the existing technical solution has only one sensing factor for judging the theft, which will lead to a high rate of misjudgment and the risk of disturbing the people.

Description of drawings

The following is a brief description of the content expressed by each piece of accompanying drawing in the specification sheet of the utility model:

Figure 1 is a block diagram of an intelligent vehicle anti-theft system.

detailed description

As shown in Figure 1, the vehicle anti-theft system is equipped with a central control box. The central control box integrates a GPS positioning module, a 4G communication module and a central processing unit. This high degree of integration is conducive to reducing costs and reducing installation space. There are three theft sensing units, which are car door touch switch, infrared detection module and vibration sensor, which are used to judge whether the vehicle is being stolen. Among them, the car door touch switch and infrared detection module are the sufficient conditions for the judgment, because when someone When entering the car normally, whether it is to pry the door or break the window to enter, one of the two sensors must be touched to improve the accuracy of the induction. The central processing unit receives the induction signals of the door touch switch, vibration sensor and infrared detection module installed on the vehicle, and outputs an alarm signal to the 4G communication module and warning module, and notifies the car owner or the police station through the 4G communication module SMS.

The system is powered by a dedicated power module, which is designed to provide power for the anti-theft system, which will not cause the car battery to lose power. The dedicated power module is connected to the electric energy output of the car generator, and when the vehicle starts, it can charge the dedicated power module. , There is a photovoltaic power generation unit on the car body, and the photovoltaic power generation module outputs electric energy to the dedicated power supply module, so that even if the vehicle is parked for a long time, the dedicated power supply module will not feed power to avoid the failure of the anti-theft system.

The system is equipped with a GPS positioning module and outputs position signals to the central processing unit; there is a solenoid valve on the fuel oil circuit of the car, and the central processing unit outputs control signals to the solenoid valve. The pinhole camera on the camera and the camera of the vehicle recorder, the video shooting uses a miniature infrared camera, which is easy to install in a hidden location, can be installed in multiple locations, and the multi-angle monitoring coverage is wider, and the infrared camera technology can improve nighttime surveillance. Ability to achieve 24-hour anti-theft without blind spots. After the system is started, when it is determined that a theft has occurred, it can perform a full set of anti-theft measures such as sound and light alarm, SMS notification to the owner, video shooting, positioning, and cutting off the car's fuel supply and power supply lines.

The warning module is a vehicle horn and a double-jump lamp. The special power supply module is provided with a power supply line connected to the warning module. The power supply line is provided with a switch unit controlled by a central processing unit. The independent power supply avoids battery feeding. Such a warning module can attract the attention of passers-by, warn and deter thieves, and make them retreat.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
