specific Embodiment approach

[0021] Specific implementation method: below in conjunction with figure 1 , detailing a specific implementation of an RFID radio frequency identification-based electric energy meter calibration console.

[0022] The energy meter calibration console based on RFID radio frequency identification includes an energy meter to be calibrated, an RFID wireless reader, a main control host computer meter calibration port, a program-controlled power source, and a standard meter. An RFID electronic tag chip is welded on the internal PCB of the electric energy meter to be calibrated, and is connected with the RFID wireless reader by a frequency identification wireless signal to store error information.

[0023] The RFID wireless reader is connected to the meter calibration port of the main control host computer through the serial port, and reads and writes the RFID electronic tag chip in the electric energy meter to be calibrated within a certain range, and sends the received error informat...

Abstract

An electric energy meter calibration operating console based on RFID radio frequency identification and a meter calibration method thereof are disclosed. The operating console comprises an electric energy meter to be calibrated, an RFID wireless reader and writer, a master control upper computer meter calibration port, a program control power source and a standard meter. The operating console is characterized in that the electric energy meter to be calibrated is connected to the RFID wireless reader and writer in a radio frequency identification wireless signal connection mode; and the master control upper computer meter calibration port is connected to the RFID wireless reader and writer, the program control power source and the standard meter through serial ports respectively. Calibration error information of the electric energy meter is automatically transmitted and meter calibration efficiency is increased.

Description

technical field [0001] The invention relates to an electric energy meter calibration console, in particular to a meter calibration method based on RFID radio frequency identification. Background technique [0002] In the traditional energy meter calibration process, the calibration console and the energy meter to be calibrated are connected through cables, and the calibration error information is transmitted to the energy meter to be calibrated through the cable. After the energy meter is calibrated, it needs to be disconnected. Unplug the cables connected to the calibration console, and then connect to the next batch of watt-hour meters to be calibrated. This energy meter calibration method requires frequent switching of cable connections, and the length of the cable also limits the communication distance, resulting in low calibration efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose an RFID-based ele...
