Carrier data safety protection method and recording system device of pre-payment meter

Abstract

A method for protecting the data of a pre-payment electric energy meter includes the following steps: sending the data of payment to a user's electric energy meter by a carrier wave of a power line; receiving the data of payment by a carrier wave module of the user's electric energy meter and storing the data to a data storing circuit; and sending the confirm information to the computer for recording meter and selling electricity power to make a check on it. A device of recording meter system includes: a computer for recording the data of the meter and selling electricity power; a recording meter junction station; a carrier wave module; a user's electric energy meter as well as down and up channels, wherein the carrier wave module which is installed together with the user's electric energy meter includes a data storing circuit made up of RA (EEPROM, FRAM) units; and wherein the down and up channels are made up of low-voltage power transmission line. According to the present invention, the distributing, using, measuring and charging of the electric power are all under the control of the computer.

Description

technical field [0001] The invention belongs to electric energy metering, control and charge management technology, in particular, it uses the power line carrier as the information channel to carry out centralized meter reading and charging, and realizes the prepayment function on each user's electric energy meter, so as to protect data information security and avoid external malicious attacks. Decentralized control management system. Background technique [0002] The metering and charging of electric energy is currently mostly done by installing electric energy meters at the power supply entrance of each user, full-time meter reading personnel come to the door to read the meter regularly, and then each user pays the fee at the toll office. This method is time-consuming and labor-intensive, and errors caused by various reasons are unavoidable. Due to the lack of effective monitoring measures to pay electricity bills, many power supply companies or property companies have mo...

Problems solved by technology

Since these two schemes still have a data input window open to users such as an IC card or a keyboard, they only increase the degree of preventing external malicious attacks, but cannot fundamentally avoid external attacks, and there is no information feedback channel to allow copying The computer for meter electricity sales often checks the user's meter reading and electricity purchase data

Therefore, there are still large security loopholes in the data information of user electricity purchase charges and electricity meter reading
