GSM car burglar alarm development trend
First, the urgency of car security
As China's reform and opening up, people's living standards continue to increase, the car has become an indispensable part of people's lives, from the world's first T-Ford stolen, theft has become the most common in today's society One of the crimes has become a serious social problem. With the increase in the number of cars, the number of stolen vehicles has also increased year by year. This has brought great instability to the community, and is concerned that the stolen cars have become the number one problem plaguing car users.
According to statistics, the largest number of automobile thefts currently occur in the United States. Each year, 1.5 million vehicles are stolen, that is, one vehicle is stolen every 20 seconds; Hong Kong also has 4,000 limousines stolen each year. From the domestic situation, the number of thefts of cars has increased in recent years. According to statistics, there were more than 100,000 cases of theft of cars in the country in 2002, and more than 300 vehicles were stolen on an average day, and in recent years, they have continued to increase. The more fierce.
Second, the history of car anti-theft development
With the advancement of science and technology, in order to deal with the ever-evolving segment of car theft, people have developed and developed anti-theft devices in different ways.
The first generation is a mechanical anti-theft device:
Divided into two major categories of steering wheel locks and gear locks. It is mainly to lock the clutch, brake, throttle or steering wheel, gear shift to achieve the purpose of anti-theft, but only anti-theft alarm. The advantage is that it is cheap and easy to install. The disadvantage is that the anti-theft is not complete, and it is more troublesome to dismantle and disassemble each time. Sometimes the owner of the vehicle will be equipped with several types of mechanical anti-theft devices, according to industry sources, this can be a certain degree to deter car thieves, or increase the likelihood of thieves being discovered. The anti-theft performance of such products is extremely low and it is rarely used on the market alone.
The second generation is an electronic anti-theft device:
In order to overcome the shortcomings of mechanical locks that do not alarm, electronic alarms have emerged. It mainly relies on locking the ignition or starting to achieve the purpose of anti-theft, at the same time with anti-theft and sound alarm function. Remote-controlled car alarm is characterized by the remote control of the entire function of the alarm, reliable and convenient, with vibration detection gate protection and microwave or infrared probes and other functions. There are also two-way electronic anti-theft devices on the market. This type of anti-theft device not only allows the owner to remotely control the vehicle within a certain distance. The vehicle can also transmit its own status to the owner, for example, which side of the door is opened or the window glass. Destruction etc. However, these types of anti-theft devices generally have false alarms and do not fundamentally solve the problem of vehicle loss. This kind of anti-theft device has a certain anti-theft function. When it exceeds the effective distance and is left unattended, its anti-theft function will also be lost.
The third generation is a chip-type digital anti-theft device:
Most of it is used in automobile original anti-theft devices. Although the anti-decoding function of the second-generation anti-theft device is solved, the distance cannot be limited. With the escalation of thieves' means, many cars equipped with original anti-theft devices have been stolen, including reports that high-segment cars such as BMW and Mercedes have been stolen.
The fourth generation is the network anti-theft system:
1. The GPS system is called Global Satellite Positioning System. It is mainly used for assisting anti-theft function derived from navigation and positioning of the car. Its advantage is that it can understand the location of every vehicle in the group's fleet in real time for effective supervision. It is mainly after the vehicle is stolen to control or locate through the service center to locate the vehicle. It is a “purchase†method after the occurrence of the police. The main drawbacks of GPS anti-theft are: First, there is no GPS in the area where the satellite positioning ground monitoring center cannot be established; second, because of the limited number of satellites, there is a certain “blind area†in the information scanning coverage, so that the monitoring is often in an intermittent “lost†state. Third, the prices are generally more than a few thousand dollars, and they have to pay hundreds of thousands to thousands of yuan each year in service fees. This will increase the extra burden on the owners and make ordinary people discouraged. Because it is through the information alarm, network coverage is incomplete and the police sent the situation is not direct, so that its anti-theft performance is greatly reduced, so the installation of a GPS car stolen repeatedly.
2. GSM network anti-theft system (represented by Guangdong Jifulong GSM car alarm) is to use the GSM global mobile network to monitor the car in real-time for 24 hours, and to call the owner's mobile phone within a few seconds of the alarm. Or voice reports on the phone, the owner can immediately monitor, shout, lock the vehicle through the incoming call, the system will automatically cut off the oil circuit, circuit, so that the car can not start, with a real sense of "anti-theft" function, theft in the fundamental, The possibility of car theft was eliminated; after the robbery, the car could be locked by phone and the lost car could be recovered through the GSM network.
GSM's mobile digital communications technology and the universal application of global mobile communications, use any mobile, fixed telephone communications to manage and monitor the vehicle, and can also start and drive without the key to the vehicle operation, to achieve unlimited time and place of the global remote Remote control and monitoring make people and vehicles get along. Humanized products and humanized functions, using voice as a platform for product function setting, operation, use, and communication, real-time, clear, and clear voice transmission remote control and alarm information completely abandon the concerns of human and vehicle separation. Abandon the traditional products of passive alarm, distance barriers, remote ignorance and out of control of the drawbacks, the car will be in their own control at any time, is the latest automotive high-tech products. The GSM network anti-theft system effectively overcomes the drawbacks of the GPS anti-theft system, such as high cost, incomplete network coverage, low anti-theft performance, and indirect alarm, and it does not need to pay service fees, and it has rapidly become the new mainstream anti-theft system.
