Two-wire controlled passive electronic lock cylinder

Abstract

The invention discloses a two-wire controlled passive electronic lock cylinder, and relates to the technical field of safety and theft prevention. The passive electronic lock cylinder consists of an intelligent key and a lock cylinder, wherein the working power supply of the lock cylinder is from the intelligent key, and two-wire control is adopted between the lock cylinder and the intelligent key. The lock cylinder consists of a microprocessor, a control module connected with the microprocessor, an execution mechanism connected with the control module, a diode D1 and a storage capacitor C1; the XIN and XOUT pins of the microprocessor are connected with the control module through the diode D1; the diode D1 is grounded through the storage capacitor C1; and the XIN and XOUT pins of the microprocessor are combined together to realize simplex communication together with the intelligent key. Because of a few control wires, the lock cylinder has simple design and process, low manufacturing cost and high reliability.

Description

technical field [0001] The invention relates to the technical field of safety and anti-theft, in particular to a passive electronic lock cylinder controlled by two lines. Background technique [0002] Existing lockset can be divided into two big classes: the one, mechanical lock class, the 2nd, electronic lock class. [0003] Mechanical locks are still the mainstream varieties in the lock industry due to their simple structure and low manufacturing cost. The mechanical lock adopts a mechanical lock cylinder, and the lock cylinder is the core of control. Due to the inability to carry out identity authentication and effective information management, incidents of keys being stolen and other illegal key holders opening locks often occur. The disadvantage of mechanical locks is that the key management security is low. [0004] With the development of electronic technology, electronic technology has been widely used in the lock industry, such as magnetic card locks, fingerprint ...

The disadvantage of mechanical locks is the low security of key management

[0004] With the development of electronic technology, electronic technology has been widely used in the lock industry, such as magnetic card locks, fingerprint locks, remote control locks, etc. There are many types of electronic locks. Most of the current electronic locks are based on traditional mechanical locks. Electronic control parts are added, so its The manufacturing process is much more complicated than conventional mechanical locks, and the cost is also greatly increased

[0005] Most of the current electronic locks adopt active design, that is, they need to provide working power for the lock. Because the use environment of the lock is very complicated, the reliability of the power supply directly affects the reliability of the lock, so the active lock cannot completely replace the traditional lock.

There are also a small number of locks that use passive design and key power supply, but there are many interface core wires, and its structure and manufacturing process are complicated.

Compared with traditional mechanical locks, electronic locks have complex technology and manufacturing processes, high manufacturing costs, and limited application range.
