New car decoration car anti-theft system strategy

Automobile anti-theft devices can be divided into four categories according to their structure and functions: mechanical, electronic, chip and network. Here are a brief introduction to these four types of anti-theft devices.

1. Mechanical lock anti-theft
Mechanical locks are the most common and earliest car anti-theft locks, mainly divided into steering wheel locks and gear locks. Most New Car owners will use the steering wheel lock, and there is no need to install it. The gear lock is generally installed on the center console, the lock body is connected to the body, and then the movement of the shift handle is restricted by the lock ring, but it needs to be drilled and installed, so not many people use it. In addition, there is a new type of transmission lock, which is directly made into a shift handle with a built-in lock. It looks very beautiful, but the price is nearly 1,000 yuan, and the original shift handle needs to be replaced.

Mechanical locks mainly play a role in restricting the operation of vehicles, and have limited help in anti-theft. It is difficult to resist the theft of heavy tools such as crowbars, hacksaws, and large scissors. However, they also have their advantages. It is a fact that it can delay the time for car thieves to commit crimes. Generally, it takes tens of seconds or even minutes for the car thief to pry off the steering wheel lock, and the time for the gear lever lock to break is longer.

2. Electronic anti-theft system
Electronic anti-theft lock is currently one of the most widely used anti-theft locks, divided into two types of one-way and two-way. The main functions of the one-way electronic anti-theft system are: opening and closing the door of the car, vibrating or illegally opening the door alarm, etc. There are also some brand products that add some functions according to customer needs: using an electronic remote control to complete engine start and flameout. The two-way visual electronic anti-theft system is much more advanced than the one-way. It can completely let the owner know the real situation of the car. When the car has an alarm, the LCD on the remote control will show the situation of the car, but the disadvantage is The effective range is only 100-200 meters.

Mastering the stick, but aiming for the yard. The electronic anti-theft system has a fatal injury: when the owner uses the remote control to open and close the door, the thief hiding in the vicinity can use the receiver or scanner to steal the radio waves or infrared rays emitted by the remote control, and then decode it to turn on the car Anti-theft system.

3. Chip digital anti-theft device
The chip-type digital anti-theft device is the focus of the development of automobile anti-theft devices. Most cars adopt this anti-theft method as the original anti-theft device.

The basic principle of the chip-type digital anti-theft device is to lock the motor, circuit and oil circuit of the car, and the vehicle cannot be started without the chip key. To unlock the lock, you must use the combination key to touch the combination lock on the car, which eliminates the drawbacks of being scanned. At present, many imported high-end cars, domestically produced Volkswagen, Guangzhou Honda, Palio and other models have been equipped with the original chip anti-theft system.

4. Network anti-theft
Network anti-theft refers to the functions of opening and closing the car, starting the motor, stopping the car, positioning the car, and the vehicle to provide remote vehicle condition reports according to the owner's requirements through the network. Network anti-theft is mainly to break the distance limit.

At present, the main networks used are: wireless network (BB machine network), GPS (satellite positioning system), of which the most widely used is GPS.

The GPS system is called "Global Satellite Positioning System". In fact, this technology is a major aerospace project in the United States that has cost more than 10 billion U.S. dollars and developed over 20 years. It was mainly used in wars at the beginning. Later, GPS technology has been more deeply applied in the non-military field, and has achieved practical results in the field of automobile anti-robbery and anti-theft. The GPS satellite positioning system is a network type anti-theft device, which mainly achieves the purpose of anti-theft by locking the ignition or starting. GPS mainly uses the satellite monitoring center to provide 24 hours of uninterrupted, high-precision monitoring services for vehicles. The system consists of a central control system installed in the command center, a mobile GPS terminal installed in the vehicle, and a GSM communication network. It receives positioning information from global positioning satellites, calculates the longitude, latitude, speed, and direction of the moving target, and uses The short message platform of the GSM network serves as a communication medium to realize the transmission of positioning information. This round-the-clock service is very effective, but its shortcomings are also obvious: the price is expensive, and there is a certain monthly service fee.
