Encryption communication and control methods for remote pre-payment electric meter

Abstract

The invention discloses encryption communication and control methods for a remote pre-payment electric meter. The methods are mainly formed by communication link management, a data encryption and decryption module, a random secret key control module, electric charge unit price and pricing method management, and a load power supply control module. Through a TEA encryption algorithm, a method of combining a fixed secret key and a random secret key is used to encrypt communication data, and system anti-attack ability is improved, system reliability is improved, and reliability of user recharge isrealized. A system can support a plurality of charging modes, to satisfy use requirement of different client bases. A real-time online recharge and fee deduction method is used, and when fee arrearage occurs, electricity is cut off immediately, use cost of users is saved, and the method provides convenience for electricity utilization charging management of residents. Users can freely expand, andthe encryption communication and control methods can be realized on various hardware platforms to support function optimization configuration under different application environments, to achieve resource optimal configuration and prevent resource waste.

Description

technical field [0001] The invention relates to the field of electric power metering and charging, in particular to an encrypted communication and control method for a remote prepaid electric meter. Background technique [0002] In the existing inventions of the same technology, through the functional modules of the unique encryption algorithm, the online safe recharging of electricity charges, etc. are realized. Most of the similar products on the market are pre-stored electricity charges by inserting a card. The card is repeatedly pulled out, the meter is maliciously damaged, the recharge card is decrypted, and the data security is low. For this reason, those skilled in the art have proposed an encrypted communication method for prepaid electric meters that can improve data security, facilitate operation, and avoid the disadvantages of other payment methods, so as to solve the problems raised in the above-mentioned background technology. Contents of the invention [000...
