A method for remotely verifying a fee-controlled electric energy meter of a radio frequency card pre-paid encryption function comprises the following steps: Step 21: The upper computer performs data communication with the electric energy meter verification device through the network switch, and reads the fee-controlled electric energy meter before being verified Parameter information; Step 22, the host computer performs data communication with the cryptophone through the network switch, requests to encrypt the remote command, and obtains the encrypted data set; in step 23, the host computer communicates with the power meter verification device through the network switch, and checks the energy meter The corresponding check-up electric energy meter on the device is written into the encrypted data set, and the to-be-checked control electric energy meter starts to execute after receiving the data set; in step 24, the upper computer performs data communication through the network switch and the electric energy meter verification device, and reads The parameter and the quantity of electricity after the verification of the energy meter are checked, and compared with the remote command requested in step 22, if the information read in this step is consistent with the remote command requested in step 22, it is determined that the fee-controlled electric energy meter is qualified. If it is inconsistent, it is determined that the fee-controlled electric energy meter is unqualified; in step 25, the upper computer stores the verification result.
Compared with the prior art, the present invention has the beneficial effects that the present invention can simulate that the user uses the card to directly perform the card swiping operation on the fee-controlled electric energy meter with the radio frequency module installed or the interactive terminal, and the information of the energy-controlled electric energy meter and the main station. The usage scenario of the secure interaction, and the cost control security test of the electric energy meter in the scenario. The card swiping operation on the main body of the electric energy meter is completed by the verification personnel, and the swiping operation on the interactive terminal can be automatically completed by the device itself through the modification. The invention solves the problem that the electric power company verification device does not have the pre-paid function verification of the radio frequency card in the process of upgrading and renovating the electric energy meter, and is convenient for the full-function verification of the electric energy meter.
