Drive protection system of electronic lock

Abstract

The invention discloses a drive protection system of an electronic lock. The drive protection system of the electronic lock comprises a door body, the electronic lock, a control system and a power module. The control system comprises a single chip control circuit and an electronic lock drive circuit. The output end of the single chip control circuit is connected with the electronic lock by the electronic lock drive circuit. The power output end of the power module is connected with the power input end of the electronic lock drive circuit by an overcurrent, overvoltage and overheating protection circuit. The inner side of the door body is provided with a USB interface. The USB interface is respectively connected with the electronic lock, the single chip control circuit, the electronic lock drive circuit and the power input end of the overcurrent, overvoltage and overheating protection circuit. The drive protection system of the electronic lock has the rational and reliable structure, is capable of providing the overcurrent, overvoltage and overheating protection to the electronic lock drive circuit so that the electronic lock drive circuit does not happen the failure, providing the emergency power under the situation of no power of the power module, and guaranteeing the normal work of a door opening system.

Description

Technical field [0001] The invention relates to the field of anti-theft doors, in particular to an electronic door lock drive protection system. 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 security level. [0003] The full name of anti-theft door is "anti-theft security door". It has both anti-theft and safety performance. According to the "General Technical Conditions for Anti-theft Security Doors", a qualified anti-theft door cannot be pried or opened on the door leaf with a chisel, screwdriver, crowbar and other ordinary hand tools and portable electric tools such as electric drills within 15 minutes. Opening, or opening a 38 square millimeter opening in a semicircle of 150 square millimeters at the locking point. And the lock used on the anti-theft door must be a...

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
