Single chip machine controlled mechanical electronic cipher lock

Abstract

The invention discloses a mechanical electric cipher lock which is controlled by a singlechip, which comprises a singlechip, cipher codes are preset in the singlechip, contact points are arranged on a lock body on the periphery of a lock pin key hole, and the contact points are correspondingly connected with an input hole and an output hole of singlechip cipher codes signals and a supply port, contactors which are matched with the number and positions of the contact points are arranged on a key, cipher codes which are corresponded with presetting cipher codes of the singlechip are arranged on the key, and the cipher codes on the key are arranged in a conservator which is fixedly arranged in the key, the contactors on the key are correspondingly connected with an input hole and an output hole of conservator codes signals and a supply port, the contactors can contact with the corresponding contact points to decode when the key is inserted in the key hole or in the process of the rotating of the key, the singlechip is provided with at least a signal output circuit, and the signal output circuit is connected with a drive component. The invention is difficult to be illegally unlocked and electric cipher codes are difficult to be destroyed, which can totally replace a mechanical door lock and an electric lock, the invention which is added with a transducer can constitute a reliable anti-theft warning system.

Description

technical field [0001] The invention relates to a mechanical and electronic combination lock, in particular to a mechanical and electronic combination lock controlled by a single-chip microcomputer. Background technique [0002] What people use now is the popular mechanical tumbler lock. For the sake of safety, people have thought of many ways to increase the difficulty of unlocking, and a pin lock with pins in both directions up and down has appeared. In recent years, there have been mechanical pin locks with pins in four directions: up, down, left, and right. Nowadays, the phenomenon of cars and motorcycles being stolen is more common and difficult to prevent. As the saying goes, this kind of lock can only be "prevent gentlemen but not villains". protective device; [0003] For this reason, electronic combination locks that use a keyboard to input a password and open it with a mechanical tumbler lock appear again; because the password is input by a keyboard, the number ...

AI Technical Summary

Problems solved by technology

Nowadays, the phenomenon of cars and motorcycles being stolen is more common and difficult to prevent. As the saying goes, this kind of lock can only be "prevent gentlemen but not villains". protective device;

[0003] For this reason, electronic combination locks that use a keyboard to input a password and open it with a mechanical tumbler lock appear again; because the password is input by a keyboard, the number of digits of the password cannot be too many, and it is difficult to remember if there are too many, and the password is easy to forget, especially when you are old. old man, can't remember

And the keyboard is also very easy to be damaged by human beings. Once damaged, the lock cannot be opened, and it is not suitable for outdoor use;

[0004] There is also an IC card lock, which only has an electronic password without the protection of a mechanical tumbler lock. The IC card reading device is easily damaged. Once damaged, the lock cannot be opened. It is also not suitable for outdoor use, and the lock tongue must be opened directly. , using a lot of power;

[0005] There is also a mechanical electronic combination lock, which is characterized in that the key is equipped with a storage medium, which is a magnetic material, which is essentially the same as a magnetic card phone, but the magnetic material can be used on phone cards and bank passbooks, and can be used on locks no, poor reliability

Because the password on the magnetic material is to be read out, the magnetic material must be in close contact with the password readout device, but the magnetic loss in the air is the largest, that is, the magnetic resistance is the largest, so the surface material of the readout device must be hard, not easy to be damaged, rough, The magnetic material on the key should also be firm and not easy to fall off, and the rotation of the key should drive the lock cylinder to rotate together. On the one hand, the lock cylinder cannot be in close contact with the lock body, and the code on the lock body will also be read out of the device surface when the lock cylinder is turned Damage, resulting in poor contact. On the other hand, the magnetic material on the key will fall off due to the friction of the key rotation, the lock body and the marble. In this way, the password on the storage medium is difficult to read without error, and the failure rate is very high.
