Electromechanical intelligent control circuit for anti-theft lock

Abstract

The invention relates to a control circuit used for an electronic lock, in particular to a control circuit used for an electromechanical intelligent burglar-proof lock, which comprises a main control module and a peripheral control circuit, wherein, the peripheral control circuit comprises a keyboard control module, a motor drive module, an electromagnet drive module, a switch detecting module, a key detecting module and a power control module; the input / output port of a microprocessor in the main control module is connected with all the functional devices in the keyboard control module, the motor drive module, the electromagnet drive module, the switch detecting module and the key detecting module; the power control module provides power for all the modules; the invention provides a control circuit used for the electromechanical intelligent burglar-proof lock, with high integration degree, good reliability and high intelligence degree.

Description

(1) Technical field: [0001] The invention relates to a control circuit for an electronic lock, in particular to a control circuit for an electromechanical intelligent anti-theft lock. (two), background technology: [0002] In the current lock industry, various forms of anti-theft locks emerge in endlessly. The general mechanical lock has poor anti-theft function because it is easy to be picked, while the mechanical combination lock requires the opener to memorize the password before it can be unlocked. For many people, especially the elderly and For children, it is difficult for them to remember a series of passwords, and it is inconvenient for users to use. At the same time, criminals may open the combination lock through long-term trial keys. Later, electronic anti-theft locks appeared, but the electronic locks used with it The key only plays the role of storing and transmitting electronic signals, and cannot transmit the mechanical power required to open the door. Its sco...

[0002] In the current lock industry, various forms of anti-theft locks emerge in endlessly. The general mechanical lock has poor anti-theft function because it is easy to be picked, while the mechanical combination lock requires the opener to memorize the password before it can be unlocked. For many people, especially the elderly and For children, it is difficult for them to remember a series of passwords, and it is inconvenient for users to use. At the same time, criminals may open the combination lock through long-term trial keys. Later, electronic anti-theft locks appeared, but the electronic locks used with it The key only plays the role of storing and transmitting electronic signals, and cannot transmit the mechanical power required to open the door. Its scope of application is limited. Once the lock or key has no power supply, it cannot be used

Because it is difficult to achieve the purpose of anti-theft or because of the inconvenience of use, the above-mentioned locks are gradually abandoned by high-end customers.

At present, the common electronic door locks mostly adopt the electromechanical combination type. The electronic signal carried by the smart chip installed on the key is used to connect the door opening circuit of the door lock, and then the mechanical structure of the key is used to transmit the power required for opening the door. Most of the control circuits of locks have low integration, poor reliability and single function.
