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

The passive electronic lock core of two line traffic controls
Technical field
The present invention relates to the safe antitheft technical field, specifically is a kind of passive electronic lock core of two line traffic controls.
Background technology
Existing lockset can be divided into two big types: the one, and mechanical lock class, the 2nd, electronic lock class.
Mechanical lock is with simple in structure, and advantages such as low cost of manufacture remain the main flow kind of lockset industry.What mechanical lock adopted is mechanical lock, and lock core is the core of control, owing to can't carry out authentication and effectively information management, key is stolen the incident that non-legal key holder opens lockset such as joins and often take place.It is low that the shortcoming of mechanical lock is exactly the key management safety.
Along with development of electronic technology; Electronic technology is used for the lockset industry in a large number, such as magnetic card lock, and Fingerprint Lock; Remote control locks etc. are of a great variety; Present electric lockset is on the basis of traditional mechanical lockset, to have increased electronic control part mostly, so its manufacturing process is much complicated than the conventional mechanical lockset, and cost also increases considerably.
Present electric lockset adopts active design mostly, just need working power be provided to lockset, and because of the lockset environment for use is very complicated, power supply reliability directly influences the reliability of lockset, so active lockset can't replace conventional lock fully.Also have a small amount of lockset to begin to adopt passive design, adopt key-poweredly, but the interface heart yearn is many, and its structure and manufacturing process are complicated.Electronic lock is compared with the traditional mechanical lockset, and technology and manufacturing process are complicated, and manufacturing cost is high, is of limited application.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, the present invention provides a kind of passive electronic lock core of two line traffic controls, and power supply only adopts two lines to control with communicate by letter, not only can satisfy the requirement that lock core is supplied power, and also has information transfer function between the while lock & key.
The present invention realizes with following technical scheme: a kind of passive electronic lock core of two line traffic controls, comprise Intelligent key and lock core, and the lock core working power derives from Intelligent key, adopts two line traffic controls between lock core and the Intelligent key; It is characterized in that: described lock core is made up of microprocessor, the control module that is connected with microprocessor, diode D1 and energy-storage capacitor C1; The XIN of microprocessor, XOUT pin are connected with control module through diode D1, and diode D1 is through energy-storage capacitor C1 ground connection; The XIN of microprocessor, XOUT pin are also realized simplex with Intelligent key together.
The invention has the beneficial effects as follows: the design and processes of lock core interface is simple, low cost of manufacture, and reliability is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Accompanying drawing is principle of the invention figure.
The specific embodiment
Shown in accompanying drawing, the passive electronic lock core of two line traffic controls mainly contains following components and forms: microprocessor: be used for control and information processing.Diode D1 utilizes the unidirectional on state characteristic of diode as the pattern control element, realizes the conversion of powering mode and communication pattern; Diode D1 provides passage for energy-storage capacitor C1 under the powering mode, and diode D1 isolates the influence of energy-storage capacitor C1 to communication process under the communication pattern.Energy-storage capacitor C1: for lock core power supply is provided under the communication pattern; Control module: under microprocessor control, carry out unlocking action, realize the conversion of electric energy to mechanical energy.Executing agency adopts micromachine or minitype electromagnet etc.Draw single line respectively as power supply and the interface of communicating by letter from the positive pole of diode D1 with ground wire.Have two kinds of mode of operations of powering mode and communication pattern between Intelligent key and the lock core, the work that hockets of two kinds of mode of operations.
The course of work: after Intelligent key inserts lock core, at first get into powering mode, charge for energy-storage capacitor C1, control the charging interval according to lock core communication pattern institute energy requirement size by Intelligent key.When the energy of energy-storage capacitor C1 storage is enough to keep the overall process of lock core communication pattern, change between Intelligent key and lock core communication pattern under and work, carry out information exchange between Intelligent key and the lock core; After the information Recognition; Need carry out unlock operation like the lock core affirmation, change powering mode between Intelligent key and the lock core once more over to, lock core is through control module driving execution mechanism (motor or electromagnet etc.); Accomplish unlocking action, the energy source of carrying out unlocking action is in Intelligent key.

Claims (1)

1. the passive electronic lock core of a line traffic control comprises Intelligent key and lock core, and the lock core working power derives from Intelligent key; It is characterized in that: adopt two line traffic controls between lock core and the Intelligent key; Described lock core is made up of microprocessor, the control module that is connected with microprocessor, the executing agency that is connected with control module, diode D1 and energy-storage capacitor C1; The XIN of microprocessor, XOUT pin are connected with control module through diode D1, and diode D1 is through energy-storage capacitor C1 ground connection; The XIN of microprocessor, XOUT pin are also realized simplex with Intelligent key together; After Intelligent key inserts lock core, at first get into powering mode, charge for energy-storage capacitor C1 by Intelligent key, control the charging interval according to lock core communication pattern institute energy requirement size; When the energy of energy-storage capacitor C1 storage is enough to keep the overall process of lock core communication pattern, change communication pattern between Intelligent key and lock core.
