The car chip inductive anti-theft system is adhering to the safety concept of “vehicle anti-theft†and “under-the-ground prevention†popular in the international automobile industry. Using the latest RFID technology, the new R&D and production technology is based on safe, reliable, simple and practical, more humanized design ideas. A generation of car anti-theft products to achieve the safety purpose of anti-theft, anti-robbery and anti-corruption.
Chip-type digital anti-theft device is the focus of the development of car alarms. Most cars use 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. The digitized password has a very low bit rate, and the password key can be used to unlock the lock on the car to prevent the scanning of the defect. At present, many high-end cars imported, domestic Volkswagen, Guangzhou Honda, Palio and other models have been equipped with the original chip anti-theft system.
At present, the 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 the key confidential information. The number of authorized spare keys, time stamps, and other background information in the system form an integral part of the transceiver's security features. In addition to its more effective anti-theft function than the previous electronic anti-theft system, the fourth-generation electronic anti-theft system has other advanced features: its unique radio frequency identification technology (RFID) ensures that the system can correctly identify the driving under any circumstances. The driver automatically recognizes his or her identity as the driver approaches or moves away from the vehicle, automatically opening or closing the lock; the original TMS37211 device can easily detect the position of the electronic key, both inside and outside the vehicle.
Car chip induction anti-theft system
1, product performance
The car chip inductive anti-theft system is adhering to the safety concept of “vehicle anti-theft†and “under-the-ground prevention†popular in the international automobile industry. Using the latest RFID technology, the new R&D and production technology is based on safe, reliable, simple and practical, more humanized design ideas. A generation of car anti-theft products to achieve the safety purpose of anti-theft, anti-robbery and anti-corruption.
2, product composition
The product consists of three parts: control host, digital lock and electronic key.
3, product features
(1) The electronic key adopts the most safe American high-tech anti-magnetic chip, which does not need battery power, waterproof, dustproof and shockproof. Each electronic key is a rolling code technology, the only code in the world, can not be copied, can not be imitated, can not be changed.
(2) The digital lock can be installed in any convenient and concealed place in the car according to the owner's habits. Only the owner knows the unlocking position.
(3) The identification distance of the electronic key and the chip sensor lock is controlled within 10cm, which completely solves the possibility of decoding and decoding in the air by decoding and scanning, and truly achieves anti-interference.
(4) The control host is equipped with a built-in secondary anti-theft device, which can effectively prevent malicious thread trimming, damage the host car and other car theft behavior, and further strengthen the anti-theft function.
(5) It is easy to install and use, does not change the state of the original car system, does not abandon the original car remote control device, and has no trouble to replace the battery. At the same time, the system itself has self-detection and self-protection functions, which is more convenient to use.
4, the operation method
(1) Before the car starts the engine, it must first be authenticated. The car mainly uses the electronic key that is carried with it to sense the position of the hidden digital lock. The distance can be within 10cm. When the “drip†is heard for two consecutive sounds, the identification is successful and the warning indicator is off. At this time, the ignition can be started normally with the car key. If the car is not started for more than 30 seconds, the system will automatically enter the anti-theft lock state again.
(2) After the car is turned off and the engine is turned off, the anti-theft system will automatically lock after 30 seconds, and the warning indicator will start to light and dim, prompting the anti-theft system to enter the automatic alert state. At this time, if there is no identification of the chip sensor lock by the electronic key, the car cannot be started.
(3) If the user chooses to switch on the alarm horn mode, the car will be started before the identity is recognized. At this time, the car horn will sound an alarm and the car will not start.
(4) Repair mode, the main card is close to the anti-theft lock. After 8 seconds, the system will make three “BiBiBi†sounds. At this time, the vehicle repair mode is entered and the anti-theft system is turned off. To access the repair mode, repeat the above.

Magic Led Ball, we also called it Led Magic Ball Light, we hang the ball on the tree, in the street, in the air to make it in a wide view. also we can put the ball on the floor or desk as well. The led magic ball light mostly for stage lighting, disco llight ball, park decoration, celebration and so on.
The Magic LED Ball can do dmx rgb Led Ball or warm white led ball, golden led ball. The standard size of the magic color led ball is 200mm diameter, 250mm diameter, 350mm diameter, 500mm diameter. and the even bigger led ball which can realize a customized design.
