Method and system for regulating and controlling metering parameters of intelligent metering equipment

Abstract

The invention provides a technical scheme for regulating and controlling metering parameters of intelligent metering equipment, and the technical scheme comprises the steps: determining a digital digest of the metering parameters of the intelligent metering equipment based on a first encryption algorithm at a supervision platform end, and determining seal data based on the metering parameters and the digital digest thereof; obtaining a digital seal based on the seal data and a second encryption algorithm; and based on the digital seal and the identification code, generating a remote transmission frame and sending the remote transmission frame to the intelligent metering equipment. At the intelligent metering equipment end, the remote transmission frame is received and analyzed to obtain the digital seal and the identification code, matching identification is carried out based on the identification code, and if the digital seal is matched with the identification code, the digital seal is decrypted based on a second encryption algorithm to obtain seal data; and then, based on a first encryption algorithm, carrying out digital digest calculation on the metering parameters in the seal data, carrying out matching identification on the metering parameters and the digital digest of the metering parameters, and obtaining the metering parameters if the metering parameters are matched with the digital digest of the metering parameters. The remote networking regulation and control of the metering parameters can be safely realized, and the metering parameters can be prevented from being tampered without authorization.

Description

technical field [0001] The present application relates to the technical field of smart metering devices, and in particular, to a technology for regulating the measurement parameters of smart metering devices. Background technique [0002] Metering equipment such as water meters, electricity meters, taxi meters, and fuel dispensers are provided with business-related metering parameters, such as segmented unit prices, cost calculation methods, and settlement fees. In order to prevent the relevant measurement parameters in the measurement equipment from being adjusted without authorization, the relevant measurement parameters are usually set before the measurement equipment leaves the factory or used, and then the physical seal is set. However, due to the adjustment of application scenarios or business needs, it is sometimes necessary to adjust the relevant metering parameters in the metering equipment in use (for example: increase or decrease segment prices, adjust segment pri...
