DDS70--中华人民共和国是一个综合的反篡改单一阶段

DDS70 PRC-A is a single phase card meter which uses IC card media for two-way communication to provide a highly secure and flexible mechanism for revenue collection, thereby allowing prepayment customers to be managed efficiently and cost-effectively. Designed for residential users, simple, elegant, prepayment systems generate advance cash flow for utilities, eliminate customer debt, reduce fraud risk and lower the costs of meter reading and billing. Utility disconnections are no longer necessary because the consumer has full control over the account, while utility revenue is safeguarded. Pay as you go Providing electricity customers with a low cost, convenient method of paying for their electricity as they use it. Themeter provides a highly secure and flexible method for revenue collection and allows prepayment customers to be managed efficiently and cost-effectively. Measuring and registration Meter records import and export energy flow in separate registers, and add the values in both directions as the labeled energy consumption Remote Programming Capability collaborate with pax-hualongs vending system,the meteroffers significant benefits both to the utility and the end user. Designed with ease of remote management in mind, it allows the utility to manage meter parameters via the IC card, thus maximising the capabilities of a full two-way payment network. Specific features such as remote change of tenancy/supplier and remote credit & debt adjustments are included, all of which can remove the requirement for a customer site visit. Data security Use special protect circuit, data of the meter is keep in nonvolatile memory for whole meter life and will lost in case of power outage. Read and write the IC card is protected by three layers of passwords. In addition, each card is set to corresponding specific meter. Non-Disconnect Facility Themeter provides a flexible non-disconnect facility, which if configured can minimise the requirement for out-of-hours customer support (on a daily basis). in another hand, it providing programmable friendly hours/emergency credit/negative credit to improve customer service.

Improved Customer Service The operation of themeter is simple for the end-user and includes a new, easy-to-read backlit LCD display. To further optimize customer support requirements, automatic reporting of IC card and meter errors via the payment network have been considered to assist with problem determination. LCD Display Different display mode: - Automatic scroll mode - Manual scroll mode Information hint: Use different code and information to indicate different operation, it is including check meter and IC card malfunction.
