Embodiment Construction

[0027] The technical solution of the present invention will be described below in conjunction with the accompanying drawings, and the 125K frequency is used as the antenna coupling frequency for illustration, and the principles of other frequencies are the same.

[0028] Such as figure 1 , 2 As shown, a circuit board and a buzzer are installed in the shell cavity composed of the upper shell and the lower shell to form an alarm, and 6 wires are drawn out from the lower side of the shell, including 48V power line, ground wire, electric door lock wire, The motor rotation detection line, the 125K antenna coil, and the electronic components on the circuit board are connected as follows:

[0029] Power module: The 48V power line is connected to the anode of diode D6, and the cathode of D6 forms a node, and there are 2 branches, 1 branch is connected to the network label V+, 2 branches are connected to one end of resistor R36, and the other end of R36 forms a node, and there ...

Abstract

The invention discloses an intelligent antitheft alarm device adopting a key. A circuit board and a buzzer sheet are arranged in a shell cavity composed of an upper shell and a lower shell to form the alarm device; six wires are led out of the lower side of the shell and comprise a 48-V power wire, a grounding wire, an electric door locking wire, a motor rotation detection wire and a 125K antenna coil. Due to an RFID (radio frequency identification) technology for the internet of things, the identity of the key is unique and a repeated code value does not exist; even if the key is copied by others, the copied key cannot open a door; mutual opening rate is zero; meanwhile, the warning sound can frighten an opener to enable the opener to stand in awe before opening the door and not get close to the door; people feel safe and quick.

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 uses radio signals to identify specific targets and read and write related data without establishing mechanical or optical contact between the identification system and specific...
