A prepayment method for non-dielectric high-security electric meters

Abstract

The invention discloses a prepayment method of medium-free high-security electricity meters. The prepayment method comprises the following steps: after purchasing electricity by a user, encoding and encrypting the recharge type, electricity purchasing times, electricity purchasing time, meter number and electricity purchasing money amount at a selling operation end to generate a digital recharge token which is remotely sent to a concentrator through a communication network and is pushed to the mobile phone of the user at the same time; sending the digital recharge token into an interactive terminal by the concentrator to decrypt and obtain the recharge type, the electricity purchasing times, the electricity purchasing time, the meter number and the electricity purchasing money amount; carrying out data and flow recombination according to the recharge type so as to be suitable for recharging different types of prepayment electricity meters. The method is compatible with state grid electricity meters and STS (Standard Transfer Specification) prepayment electricity meters, and repeated construction of prepayment systems is prevented, and the waste of manpower and material resources is reduced; as an independent part, the interactive terminal is suitable for different types of prepayment electricity meters.

Description

technical field [0001] The invention relates to the field of electric meter prepayment, in particular to a prepayment method for a non-medium high-safety electric meter. Background technique [0002] The long-term business model of the power industry in the past is to use electricity first, and then pay the bill. The traditional method of collecting electricity bills: users need to pay at a designated outlet and at a fixed time. Phenomena, although legal means can be used to recover part of the loss after the event, but it often involves a considerable amount of manpower and material resources of the power company, which brings a lot of trouble to the normal operation of the power company. It has always been the goal of power companies to maximize the convenience of the vast majority of honest and trustworthy users to use electricity and pay bills, and to use economic and technical means to reduce the loss of arrears. Practical experience has proved that the promotion and a...

In addition, the recharge card itself is expensive and cannot resist physical and electrical (static interference) attacks. Once the card is lost or damaged, it must be replaced at an outlet equipped with a dedicated card reading and writing system and equipment.

This not only brings troubles to users, more importantly, power companies need to set up outlets for this, which increases operation and management costs, and it is not easy to improve customer satisfaction

[0006] Regardless of using a card-type prepaid meter or an STS prepaid meter for local recharge, the user will be in direct contact with the measuring instrument, and there are potential safety risks in electricity use, such as electricity theft, etc.

[0007] In the current electricity consumption environment, there are various prepaid meters. The power company must build a prepaid system for each type of prepaid meter. There are too many repeated investments, and it will also cause confusion in management.

[0008] With the development of communication, electronics and other technologies, the traditional method of collecting electricity bills no longer meets the needs of users and power companies. At the same time, the concept of energy saving and low carbon is becoming more and more popular. Achieve the goals of high security, high efficiency, low cost, convenience and freedom, and high participation shared by users and power companies
