Computers are becoming more and more popular, and the use of computer technology has been widely used. The ceramic bead electronic anti-theft technology has matured, and it is equipped with intelligence and automation. This ceramic bead electronic anti-theft device is suitable for various models, and can lock, prevent theft and alarm in all directions.
At present, the development of car identification keys has successfully produced a "car identification key"-ceramic bead electronic anti-theft key. The principle is simple and complex:
①, the radio frequency transponder is trapped in the car key, and a special identification code that matches the specific vehicle is stored in the transponder;
② When the key is inserted into the power switch and turned, the transponder installed inside the ignition lock reads the identification code in the key. If the signal is on, the car starts, otherwise the car cannot start.
Ceramic bead electronic anti-theft key is an electronic ignition key with ceramic beads embedded in it. And the ceramic beads on each key have a corresponding code to match them. When the ceramic bead electronic anti-theft key is inserted into the ignition switch, the electrical contact in the key cylinder measures the resistance of the key and transmits the information to the component. If the resistance value is the same as that of ceramic beads, you can start the car, otherwise you cannot start the ignition.
The characteristics of the ceramic bead electronic anti-theft key are: the key of this key is to input the biological characteristics of the human body as a password, which is identified by a computer and controlled to unlock, so the intelligent degree of the ceramic bead electronic anti-theft key is quite high. This is a development trend of automobile anti-theft electronic locks.
