Encrypted detection method for consistency of electric energy metering equipment and electric energy metering equipment consistency comparison system

Abstract

The invention discloses an encrypted detection method for the consistency of electric energy metering equipment, which comprises the steps that a workstation is started and performs identity authentication with a first security encryption controller; the workstation sends a control command to a consistency detection device, starts a signal source, and controls voltage, current and a power factor according to consistency detection logic; the workstation reads the consistency detection logic, is connected to the first security encryption controller and a second security encryption controller and performs bidirectional identity authentication through a first encryption channel; the workstation is connected to the first security encryption controller, the second security encryption controller, detected electric energy metering equipment and reference electric energy metering equipment, and performs bidirectional identity authentication through a second encryption channel; the workstation reads a target code ciphertext of the reference electric energy metering equipment, sends the ciphertext to the first security encryption controller, also reads a target code ciphertext of the detected electric energy metering equipment and sends the ciphertext to the second security encryption controller; and the workstation verifies each frame of ciphertext data and stores the verified ciphertext data to a target code ciphertext library of the detected electric energy metering equipment. The invention further discloses an electric energy metering equipment consistency comparison system.

Description

technical field [0001] The invention relates to an encrypted detection method and a system device for software consistency comparison of intelligent metering equipment. Background technique [0002] The complexity of the current electric energy metering equipment software is getting higher and higher. In order to verify the consistency and reliability of the software, the power grid company has formulated a comparison scheme that meets the requirements of relevant technical specifications. The main defects are as follows: during the software comparison process, equipment manufacturers need to provide codes, which may easily lead to code leakage; data is transmitted in plain text during the comparison process, which is easy to be intercepted by eavesdroppers; only simple passwords are used for verification, and software comparison cannot be guaranteed. Reliability to personnel. Contents of the invention [0003] The present invention solves the above-mentioned technical de...
