Car anti-theft development direction - intelligent

Car alarm is a high-tech anti-theft product integrating GSM network digital mobile communication technology and GPS satellite positioning technology. It is a new generation of automobile anti-theft products following one-way anti-theft devices and two-way anti-theft devices. It uses mobile communication networks to completely solve the problem of distance limitations and easy to crack problems that cannot be solved by common anti-theft devices. In addition to the function of an ordinary anti-theft device, it also has functions such as mobile phone control, SMS positioning, remote monitoring, remote alarm, and full voice prompt operation. Whenever and wherever you are, you can monitor your car by phone to get the best protection.

At present, there are four main types of anti-theft devices: mechanical, electronic, chip-based and network-based. Their advantages and disadvantages are different. However, the direction of the development of car theft prevention is to a higher degree of intelligence and chip-type networks. Development.

The mechanical anti-theft device is a variety of anti-theft locks made of metal materials, including steering column locks, steering wheel locks, shift lever locks, pedal locks (clutch pedal locks, brake pedal locks), wheel lock wait until, through these anti-theft locks Locking the car's controls so that thieves can't drive the car away.

Now it is rarely used alone. It is mainly used in combination with electronic and chip type. It is mainly divided into two categories: steering wheel lock and gear lock. Most of the steering wheel locks will be used by the owner, and they do not need to be installed. The gear lock is generally installed on the center console, the lock body is connected with the body, and then the lock handle is moved through the lock ring, but the drill needs to be 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 is replaced, and there are fewer users.

The most widely used are steering wheel locks, gear locks, and throttle locks. Prices range from 100 yuan to 1,500 yuan. The main role is to shock theft. The new car can buy a baseball bat type steering wheel lock, which can increase protection and play a defensive role.

Mechanical locks mainly serve to limit the operation of the vehicle, and they provide limited assistance for anti-theft. It is difficult to resist the theft of heavy tools such as shovels, hacksaws, and large scissors. However, it is a fact that they can delay car thief crimes. In general, car thief use dozens of seconds or even minutes to open the steering wheel lock, and the shift lever lock breaks down even longer.

Electronic anti-theft devices, also known as microcomputer anti-theft devices, mainly insert, push-button and remote control and other types. The anti-theft device controls the starting and ignition circuits of the car through electronic equipment. When the entire system is turned on, if there is illegally moving the car, opening the door, fuel tank door, engine cover, trunk cover, and ignition circuit, the anti-theft device will immediately issue an alarm. The flashing light flashes and the siren works. At the same time, the starting circuit, the ignition circuit, the fuel injection circuit, the fuel supply circuit, and even the automatic transmission circuit are cut off and the vehicle is completely paralyzed. The anti-theft device is concealed, full-featured, wireless remote control, and easy to operate. It is an anti-theft device widely used in medium- and high-grade cars.

The electronic anti-theft lock is one of the most widely used anti-theft locks and is divided into two kinds of one-way and two-way. One-way electronic anti-theft system's main function is: the car's opening and closing doors, vibration or illegally open the door alarm, there are also some brands of products according to the needs of customers to increase some of the features: the use of electronic remote control to complete the engine start, turn off and so on. The two-way visual electronic anti-theft system is more intuitive than one-way, and can completely let the owner know the actual situation of the car. When the car has a change alarm, the liquid crystal display on the remote controller will show the status of the car. The disadvantage is effective. The range is only 100-200 meters.

The fatal flaw of the electronic anti-theft system lies in its electronic password and remote control mode. When the owner uses the remote control to open or close the door, a thief hiding in the vicinity can use the receiver or scanner to steal radio waves or infrared rays from the remote control. After decoding, the car's anti-theft system can be turned on.

The chip-type chip digital anti-theft device adopts radio frequency technology and is controlled by a chip-type smart card, which locks the oil circuit and circuit of the automobile and enables the automobile to play the anti-theft function. Good anti-theft performance, anti-locking, anti-decoding.

Chip-type digital anti-theft devices are now the focus of the development of car alarms. Most cars use this type of anti-theft device as the original anti-theft device.

The basic principle is to lock the motor, circuit and oil circuit of the car, and it is impossible to start the vehicle without a chip key. Currently imported many high-end cars, domestic Volkswagen, Guangzhou Honda, Palio and other models have been installed with the original chip anti-theft system.

At present, chip-type anti-theft has been developed to the fourth generation. The latest generation of the fourth-generation electronic anti-theft chip has a special diagnostic function, that is, the authorized person can obtain the history information of the anti-theft system when reading key security information. The number of authorized spare keys, time stamps, and other background information in the system form an integral part of the security features of the transceiver. The fourth-generation electronic anti-theft system has more advanced features than the previous electronic anti-theft system, but also has other advanced features: its unique RFID technology can ensure that the system can correctly identify the driving under any circumstances. The driver can automatically identify the identity of the driver when approaching or moving away from the vehicle and automatically open or close the vehicle lock. The original TMS37211 device can easily detect the position of the electronic key, whether inside or outside the vehicle.

Network security:

Network anti-theft refers to the realization of the car's door opening and closing, starting the motor, stopping the car, positioning of the car through the network, and the vehicle will provide remote vehicle condition report and other functions according to the owner's request. Network burglary is primarily a breakthrough in distance limitations.

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. GPS satellite positioning system is a network-type anti-theft device, which mainly aims to prevent theft by locking the ignition or starting. The application of GPS in car anti-theft anti-theft services is benefited from the 24-hour uninterrupted and high-precision monitoring service of vehicles by satellite monitoring centers. The system consists of a central control system installed in the command center, a mobile GPS terminal installed on the vehicle, and a GSM communication network. It accepts positioning information from global positioning satellites, calculates the longitude, latitude, speed, and direction of the moving target, and uses it. GSM network short message platform as a communication medium to achieve the transmission of positioning information, with the traditional GPS communication program can not be compared to the advantages.

GPS anti-theft device is the most advanced anti-theft setting. However, GPS anti-theft devices are more expensive than ordinary anti-theft alarms and require additional service fees, so the popularity is not high. The GSM mobile anti-theft device is based on the GSM communication network, combined with intelligent anti-theft mobile phones and cars, the alarm of this type of anti-theft device is not limited by distance, covering a wide range of networks, but need to pay the monthly fee for GSM number. At present, it is only applied to a few high-end models. There must be a GPS navigation system in the car. The installation price is more than 2,000 yuan, and the service fee for a certain fee is also paid every month. At present, it has not yet become popular.
