With the large number of cars entering the family, the increasingly rampant cases of car theft are also on the rise. According to statistics, the number of stolen cars in the world is as high as nearly 10 million per year. How to effectively prevent car theft has become a worldwide topic. In recent years, scientists have continuously introduced new types of anti-theft devices for automobiles, which has brought the car anti-theft technology to a new level.

With the development of electronic technology, the form of electronic locks for automobiles is also increasing. Currently, electronic code locks are more advanced. When the key is inserted into the electronic lock hole, the electronic code transmitter hidden in the key handle sends a password signal, and the two-way data communication is performed with the controller through the read/write coil, and the controller's authentication circuit compares the passwords. The controller also performs password identification with the electronic control unit (ECU) of the engine management system. Only the two parts of the password are “confirmed without errorsâ€, and the controller's identification circuit outputs an electrical signal, allowing the ECU to perform the next action to start the engine. Through electronic technology, the key can be distinguished into the "primary and secondary" identity, that is, the main key and the secondary key. The main key can open all the locks on the car, including the door, the trunk lock, the glove lock, etc., and the secondary key can only open the door. Lock and ignition lock. Its role is to protect the owner's personal belongings from infringement.
In recent years, a variety of biometric locks have appeared on the car, providing great convenience to the owner. The characteristic of this kind of lock is that the human biological characteristics such as sound and fingerprint are input as a password, which is recognized by the computer and controlled to unlock. Therefore, the safety of the bio-lock is quite high, and it is also the development trend of the car anti-theft lock. The fingerprint lock is a kind of automobile door lock which is made by using different characteristics of each person's fingerprint pattern. When making the first, enter the fingerprint image of the owner in the lock. When the owner opens the door, just press the finger to the door and press the button. If the fingerprint pattern matches, the door will open. Retinal locks are car door locks that are controlled by retinal patterns. The lock has a retina recognition and memory system. When the owner unlocks, he only needs to close the door lock to see it. When the retina pattern matches the record, the door will open automatically, otherwise the person will be rejected.
Although the use of high-tech keys can make the common car theft means such as destroying car locks useless, but this practice is still not perfect, the thief still has the means to steal the car, such as stealing the key or directly grabbing the car. British scientists have recently invented a remote-controlled engine to turn off the anti-theft device, even if the car is stolen, can quickly catch the criminal and find the car.
The remote control engine shutdown anti-theft device is a control box that integrates a miniature radiotelephone, microprocessor, memory and GPS satellite positioning receiver. In a car equipped with such a device, if the remote control engine is turned off and the driver has not been authenticated (such as typing an identification number), it will send a wireless message indicating that the car was stolen to the monitoring center. signal. After receiving the signal, the staff of the monitoring center will contact the owner to confirm whether the car is lost. If the situation is true, the monitoring center will use GPS to track its route and notify the police. When the car is parked safely, the monitoring center sends a signal to cut off the car circuit. In order to start the car again, you need to wait for the monitoring center to send another unlock signal. It is reported that this device was introduced to the market this year.
Spring-type terminals are new types of spring-type terminals, which have been widely used in the world's electrical and electronic engineering industries: lighting, elevator control, instrumentation, power, chemistry, and automotive power.
If the terminal block is black, one of the possibilities is not necessarily burning black, oxidation may also be black. So how to verify whether it is burnt black? The method we take is to wipe it with a finger. If it can be wiped off, like soot, it is the black substance formed by oxidation, which can only be ground off with sandpaper or a file.
