Electronic door lock driving protection and door opening overtime automatic alarming system of security door

Abstract

The invention discloses an electronic door lock driving protection and door opening overtime automatic alarming system of a security door. The automatic alarming system comprises an electronic door lock, a proximity switch, a metal sheet, a DSP control system, a GPRS module, a time delay circuit, an electronic door lock driving circuit, a power source module, an alarming lamp, a buzzer and a USB interface for providing an emergency power supply; a single-chip microcomputer is connected with the proximity switch, the time delay circuit is connected with the alarming lamp and the buzzer, the GPRS module is in communication with a mobile terminal, and the electronic door lock driving circuit is connected with the electronic door lock; and the power supply output end of the power source module is connected with the power supply input end of the electronic door lock driving circuit through an overcurrent, overvoltage and overheating protection circuit. The electronic door lock driving protection and door opening overtime automatic alarming system is reasonable and reliable in structure, overcurrent, overvoltage and overheating protection can be provided, the emergency power supply can be provided under the condition that the power source module is out of power, the opening time of the door can be detected, automatic alarming will be carried out for reminding if overtime occurs, and the safety factor and the anti-theft effect are improved.

Description

technical field [0001] The invention relates to the field of anti-theft doors, in particular to an electronic door lock drive protection and door-opening timeout automatic alarm system for anti-theft doors. Background technique [0002] The anti-theft door is equipped with an anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time, has certain safety protection performance and meets the corresponding anti-theft safety level. [0003] The full name of anti-theft door is "anti-theft safety door". It has both anti-theft and safety performance. According to the "General Technical Conditions for Anti-theft Safety Doors", a qualified anti-theft door cannot be pried open by ordinary hand tools such as chisels, screwdrivers, crowbars, and portable electric tools such as electric hand drills within 15 minutes or a 615 square millimeter hole can be opened on the door leaf. opening, or a 38 mm2 opening within a semicircle of 150 mm2...

AI Technical Summary

Problems solved by technology

In the actual working process, its driving circuit is prone to failure under overcurrent, overvoltage and overheating conditions, resulting in the failure of the entire door opening system to work normally; in addition, because it is not equipped with any emergency power supply, the power supply module used Once there is no power, the entire door opening system will be paralyzed

[0005] In addition, in the actual use process, other people, even criminals, can easily enter the room due to human negligence, which often causes the privacy to be disclosed and even cause unnecessary property losses.
