Key smart anti-theft alarm

Abstract

The invention discloses a key intelligent anti-theft alarm. A circuit board and a buzzer are installed in a shell cavity formed by an upper shell and a lower shell to form an alarm. Six wires are drawn from the lower side of the shell, including a 48V power line, a ground Wire, electric door lock wire, motor rotation detection wire, 125K antenna coil, the RFID technology added to the Internet of Things in this invention makes the identity of the key unique and has no repeated code value.

Description

technical field [0001] The invention relates to a wireless anti-theft alarm for a mechanical key, in particular to an intelligent key anti-theft alarm for a mechanical key and a radio frequency identification (RFID) technology. Background technique [0002] Traditionally, mechanical locks are used for anti-theft. The mutual opening rate of mechanical locks is high. One key can open many locks. Different lock cylinder styles are used to reduce the mutual opening rate of locks, which increases the difficulty of mechanical lock and key manufacturers. brought about a price increase for the product. If the key is copied by others, personal information and property will be lost. [0003] Radio Frequency Identification (RFID), also known as radio frequency identification, is a communication technology that identifies specific targets through radio signals and reads and writes relevant data without establishing mechanical or optical contact between the identification system and spe...
