Anti-theft alarm technology

With the development of economy and science and technology, new technologies and NEW Products for automobile anti-theft at home and abroad continue to emerge. France has applied GPS satellite monitoring technology to car anti-theft devices and has entered a practical stage. This has opened up a new idea for the development of domestic anti-theft technology. Foreign anti-theft products continue to flood the domestic market. In China, more stringent standards have been set in the area of ​​automobile anti-theft regulations, and a large amount of money has been invested in actively developing new products. Therefore, major domestic manufacturers should seize the opportunity to rationally use advanced foreign anti-theft technology and establish an effective vehicle theft prevention technology development system to promote the rapid development of domestic automobile theft prevention technology. Anti-theft alarm in China's car waves usher in new opportunities for development, and the future development will be safe, simple and intelligent.

First, the development of anti-theft alarm

1, inevitable longer development period

Due to the domestic economy, unbalanced development of science and technology, and the existence of regional differences, the demand for anti-theft products and technologies varies among automotive users of different grades, and it will take a while for the new technologies and new products for automobile anti-theft to be widely promoted in China. At present, although the development of automobile anti-theft technology at home and abroad is quite rapid, but for the core technologies of automobile anti-theft, there are widespread external closure phenomenon in the world, resulting in the relatively slow development of domestic automobile theft prevention technology, and a long-term development process is needed to catch up. Developed countries.

2. Towards security, simplicity, intelligence, and diversification of functions

At present, the widespread use of automobile anti-theft devices at home and abroad has the disadvantages of complicated structure, high price, single function and poor reliability, and cannot achieve real anti-theft. To realize real anti-theft, it is necessary to further improve the flexibility and applicability of the product. Control technology, data communication and network technology should be applied to the field of automobile anti-theft, making the car anti-theft device safe, simple, highly intelligent and versatile. The direction of development. In recent years, the popular remote-controlled lockless system is only a preliminary manifestation of intelligentization and diversification of functions. In the future, the automobile anti-theft devices will also develop in the direction of diverse identifications such as electronic passwords.

The development level of automobile anti-theft technology reflects the level of development of a country’s science and technology and the level of civilization. It is necessary to improve the technical level of domestic automobile theft prevention as soon as possible and narrow the gap with the developed countries in the world. Combining domestic actual conditions, we insist on independent research and development, and at the same time introduce advanced foreign technology and equipment, attach importance to the research and promotion of car anti-theft technology, and gradually increase the level of car anti-theft technology.

Second, the vehicle anti-theft alarm technology analysis

Anti-theft alarm for vehicles Due to the huge market prospects, many different types of products have emerged, and the structure and characteristics of their products are different.

1. Mechanical anti-theft device

A relatively common anti-theft device, mainly using a simple mechanical principle to lock a part of the car, so that it can not effectively play its due role in order to achieve the purpose of anti-theft. The advantage is that the price is cheap, and the installation is simple; the disadvantage is that the use is not concealed, the anti-theft is not thorough, and the disassembly is troublesome. After undergoing several technical upgrades, it now has more reliable steering wheel locks and gear locks. In addition, in order to increase the anti-theft security factor, the vehicle is equipped with several kinds of mechanical anti-theft devices, which can scare the thief to a certain extent and increase the possibility of the thief being discovered.

2. Electronic anti-theft alarm device

To overcome the shortcomings of the mechanical lock can only be anti-theft can not alarm, mainly by locking the ignition or starting device to achieve the purpose of anti-theft, while having voice alarm and other functions. Electronic anti-theft device design is more advanced, complex structure, including start control, remote control car doors and alarm parts, mainly by the anti-theft control unit, reading coils, warning lights, remote control keys and other components. Electronic anti-theft devices generally have a remote control function, which is concealed and easy to operate. The disadvantage is that it is prone to false positives and cannot fundamentally solve the problem of vehicle loss. Of course, with the development of science and technology, electronic anti-theft devices have also added many convenient and practical additional functions. Nowadays, electronic anti-theft devices with two-way functions have appeared on the market. Not only can the owner control the vehicle, the vehicle can also transmit its own status to the owner.

3, chip anti-theft device

By locking the braking device, circuit and steering wheel for anti-theft purposes, the vehicle cannot be started without a chip key. The digitized password code rate is extremely low, and the coded key must be used to access the coded lock on the car to unlock it and eliminate the possibility of being scanned. Due to its outstanding features and ease of use, most cars use it as the original anti-theft device. At present, domestic Volkswagen, Guangzhou Honda, Palio and other models are equipped with the original J1 chip anti-theft system. It has been developed to the fourth generation, with special diagnostic functions, not only more effective than electronic anti-theft systems, but also has other advanced features: the use of unique radio frequency identification technology between the electronic chip key and the digital lock can guarantee the system under any circumstances The driver can be correctly identified. When the driver is approaching or moving away from the vehicle, his identity can be automatically recognized and the lock can be opened or closed. The original TMS37211 device detects the position of the electronic key, whether it is inside or outside the vehicle.

4, network type anti-theft system

It realizes the starting, stopping and positioning of vehicles through the network, and can provide remote vehicle status reports and other functions according to the owner's requirements. The main use of the network is CPS, it is to lock the ignition or start the engine to achieve the purpose of theft. The network-based anti-theft system breaks through the distance limit and covers a wide range of areas. It can be used for tracking and detection of a stolen vehicle. It can be used throughout the day, has a fast detection speed, and has high monitoring and positioning accuracy. GPS anti-theft technology can be said to be a technological revolution. It can change the passive, isolated and helpless passive services of traditional anti-theft devices. It can provide all-round active services for car owners, which is unmatched by other types of anti-theft systems. However, the level of development of network-based anti-theft technology in China is relatively backward, and there is still a clear gap with developed countries.

5, other anti-theft system

An inventor in Jilin, China has now successfully developed a D816 full-range remote control car alarm. This type of anti-theft device is suitable for all kinds of vehicles, including full-vehicle, all-round anti-theft, alarm and locking functions. In addition to the owners, anyone who wants to start or smash, disassemble, hit a car, steal a tire or carry goods on the vehicle will emit a powerful alarm sound of not less than 120 decibels. The remote control can be carried around.
