The invention discloses a radio frequency card reader quick connection device used for supporting the operation of an electric energy meter calibrating apparatus. The radio frequency card reader quick connection device comprises a guide rod for the plug-in connection of an electric energy meter calibrating apparatus holder, and a guide rod U-shaped slot for the fixation of a radio frequency card reader. The guide rod U-shaped slot is fixedly connected with the guide rod. The invention also discloses the application method of the above device. The method comprises the steps of punching at least one profiled guide slotted hole besides the location of the electric energy meter calibrating apparatus, adjusting the guide rod to be at a desired installation depth, driving a position-limiting piece to slide downwards into a guide rod clamping slot, tightening screws, stabilizing the guide rod, placing the radio frequency card reader in the guide rod U-shaped slot, locking the radio frequency card reader and fixing the radio frequency card reader, wherein the guide rod can radially slide inside the guide slotted hole and cannot rotate. According to the technical scheme of the invention, only the electric energy meter calibrating apparatus holder needs to be modified, so that the modification operation is smaller in degree and easy to implement. The cost is lower. Meanwhile, the radio frequency card reader quick connection device is simple in structure, so that the installation and the operation of radio frequency card readers are facilitated. Therefore, the calibrating efficiency of the electric energy meter calibrating apparatus is greatly increased.
Description
technical field [0001] The invention relates to the technical field of electric energy meter detection, in particular to a quick connection device for a radio frequency card reader used in an electric energy meter verification device and a method for using the same. Background technique [0002] The dual-mode tariff control electric energy meter has two modes of local and remote tariff control. The local tariff control mode refers to local metering, local billing, and local switch control. The remote tariff control mode refers to local metering and remote master station billing, and The switch control is realized through the remote master station. The dual-mode fee-controlled electric energy meter interacts with security information through the radio frequency IC card and the security module embedded in the meter, and realizes data encryption / decryption, two-way identity authentication, access control and other fee control function operations. The radio frequency IC card is ...
