Introduction to safe and practical car chip induction anti-theft system

The car chip sensing anti-theft system is based on the popular safety concepts of "whole car anti-theft" and "bottom-level prevention" in the international automotive industry. It uses the latest RFID technology and is based on the design concept of safety, reliability, simplicity, practicality and more humaneness. It is a new generation of car anti-theft products developed and produced to achieve the safety purpose of car anti-theft, anti-robbery and anti-destruction.

Car chip induction anti-theft device

Chip-type digital anti-theft devices are the focus of the current development of car anti-theft devices, and most cars use this anti-theft method as their original anti-theft devices.

The basic principle of the chip-type digital anti-theft device is to lock the motor, circuit and oil circuit of the car, so that the vehicle cannot be started without the chip key. The digital password has a very low duplication rate, and the password key must be used to touch the password lock on the car to unlock it, eliminating the problem of being scanned. At present, many imported high-end cars, domestic Volkswagen, Guangzhou Honda, Palio and other models have been equipped with original chip anti-theft systems.

At present, chip-based anti-theft has developed to the fourth generation. The latest fourth-generation electronic anti-theft chip has a special diagnostic function, that is, when the authorized person reads the key confidential information, he can obtain the historical information of the anti-theft system. The number of authorized spare keys in the system, time stamps and other background information have become part of the transceiver's security features. In addition to being more effective in preventing theft than previous electronic anti-theft systems, the fourth-generation electronic anti-theft system also has other advanced features: its unique radio frequency identification technology (RFID) can ensure that the system can correctly identify the driver under any circumstances, and can automatically identify the driver's identity and automatically open or close the car lock when the driver approaches or moves away from the vehicle; whether inside or outside the car, the original TMS37211 device can easily detect the location of the electronic key.

Car chip sensing anti-theft system

1. Product performance

The car chip induction anti-theft system adheres to the security concepts of "whole vehicle anti-theft" and "bottom-level prevention" popular in the international automotive industry, uses the latest RFID technology, and is a new generation of car anti-theft products developed and produced with the design concept of safety, reliability, simplicity, practicality and more humaneness, to achieve the security purpose of car anti-theft, anti-robbery and anti-destruction.

2. Product composition

The product consists of three parts: control host, digital lock and electronic key.

3. Product Features

(1) The electronic key uses the safest American high-tech anti-magnetic chip, does not require battery power, and is waterproof, dustproof and shockproof. Each electronic key uses rolling code technology, with a unique global code that cannot be copied, imitated or changed.

(2) The digital lock can be installed in any convenient and hidden place in the car according to the owner's habits. Only the owner knows the unlocking location.

(3) The identification distance of electronic keys and chip induction locks is controlled within 10 cm, which completely eliminates the possibility of decoding and cracking by decoding and scanning in the air, and truly prevents interference.

(4) The control host is equipped with a built-in secondary anti-theft device to more effectively prevent malicious thefts such as cutting the wires and damaging the host, further strengthening the anti-theft function.

(5) Easy to install and use, without changing the original vehicle system status, without discarding the original vehicle remote control device, and without the trouble of replacing batteries. At the same time, the system itself has self-detection and self-protection functions, making it more convenient to use.

4. Operation method

(1) Before starting the car engine, identity verification must be performed first. The owner uses the electronic key he carries with him to sense the position of the hidden digital lock within a distance of 10 cm. When he hears two consecutive "beep" sounds, it indicates that the identity recognition is successful and the warning indicator light goes out. At this time, you can use the car key to start the ignition normally. If the car is not started for more than 30 seconds, the system will automatically enter the anti-theft self-locking state again.

(2) After the car is turned off, the anti-theft system will automatically lock the car after 30 seconds, and the warning indicator light will start to flicker, prompting the anti-theft system to enter the automatic warning state. At this time, if the electronic key does not recognize the chip sensor lock, the car cannot be started.

(3) If the user chooses to turn on the alarm horn and starts the car before identity recognition, the car horn will sound and the car will not start.

(4) Repair mode: Place the main card close to the anti-theft lock for 8 seconds and the system will emit three "BiBiBi" sounds. This will enter the repair mode and the anti-theft system will be turned off. To enter the repair mode, repeat the above steps.
