RFID electronic lock

Abstract

The invention provides an RFID electronic lock which mainly comprises an insulated body, a rod and a circuit module. The insulated body is provided with a three-dimensional spiral antenna and an annular metal ring, the internal surface of which is embedded with a C-shaped ring. The antenna is provided with an antenna probe extending and protruding from the metal ring. A first part of the rod is cone-shaped and coated with insulating materials, while the second part without insulating materials is provided with the annular groove on the external surface. The circuit module is embedded with a wireless radio frequency identification chip (RFID) and packaged inside the rod; therefore an RFID reader can read electromagnetic waves which contain the identification code and is sent by radio frequency identification chip in the RFID electronic lock via the antenna.

Description

technical field [0001] The invention relates to an RFID electronic lock, in particular to an omnidirectional passive electronic container lock provided with a three-dimensional helical antenna without power supply. Background technique [0002] Maritime transportation is an indispensable part of international trade. As the era of global logistics and logistics is unfolding, all countries are thinking about how to reduce the operating costs of the industry, speed up the customs clearance of containers, and improve the international competitiveness of ports. In addition, in order to solve the problem of time and manpower consumption caused by the use of traditional mechanical container locks to manage containers, and to completely realize the safety protection of re-export containers, various countries have tried their best to combine the automatic access control system with the container dynamic database system. , to enhance the capability of the container safety monitoring s...

Problems solved by technology

[0008] Although the above-mentioned electronic seal can effectively solve the inconvenience of traditional known mechanical seals, and can quickly detect whether the electronic seal is damaged and / or the advantage of the container being invaded, it still has structural shortcomings and functional Restrictions on the above, including for example: the antenna pin and the pin on the conductive pin must be aligned in order to make it electrically connected to the antenna of the electronic seal, and to play the role of the electronic seal; secondly, the electronic seal The signal transmission between the antenna and the RFID reader is directional, so the electronic seal must be fixed on the latch so that the side where the antenna is placed is opposite to the RFID reader, so that the electronic Signal transmission and reception between the seal and the RFID reader
