水資源智能管理系統（大口徑水表管理系統）專(zhuān)供大口徑水表用戶(hù)使用 一個(gè)用戶(hù)安裝一套系統需要配備系統卡（一張）和管理卡（一張或多張）：系統卡對用戶(hù)系統進(jìn)行注冊，只在系統安裝后使用一次；管理卡加強用戶(hù)系統權限管理，用戶(hù)在補購和刪除預購記錄時(shí)需要該卡。系統卡和管理卡采用邏輯加密卡，實(shí)行嚴格加密，保證卡中數據安全可靠。
售點(diǎn)管理系統：可以兼容單、三相兩種電表的管理。一個(gè)用戶(hù)安裝一套系統需要配備系統卡(一張)和管理卡(一張或多張)：系統卡對用戶(hù)系統進(jìn)行注冊，只在系統安裝后使用一次，根據用戶(hù)系統卡中信息，系統自動(dòng)決定用戶(hù)的系統只做單相表管理，還是只做三相表管理，或者同時(shí)管理單、三相兩種表；管理卡加強用戶(hù)系統權限管理，用戶(hù)在補購和刪除預購記錄時(shí)需要該卡。系統卡和管理卡采用邏輯加密卡，實(shí)行嚴格加密，保證卡中數據安全可靠。
熱量表管理系統：熱量表管理系統V1.0，專(zhuān)供預付費熱量表用戶(hù)使用。采用基本費、熱量費兩種單價(jià)收費的方式收費。采暖部門(mén)每年按居住面積向用戶(hù)收取一次基本費用，再按用戶(hù)購熱量收取熱計量費用。
管理系統做到界面美觀(guān)，操作簡(jiǎn)便，安全可靠。
GENERAL CHARACTERISTICS
BASIC CHARACTERISTICS
Data is transferred by IC card between the management system and meter(s) to realize prepayment function;
Easy installation, friendly user interface, user manual bound in system software;
High density encryption of user card, strict encryption confirmation between meter and user card. It prevents duplication of user card by users;
Transaction record can be tracked and printed in terms of user name, time and area, for check-up of “zero transaction” users in long time period.
System operators are authorized by different levels of access, given different jurisdictions (to prevent fraud).
Transaction record can only be revised or deleted with cryptograghic key (password).
Database is supported periodically for safety in unexpected accidents.
BASIC PROCEDURE FOR NEW SUBSCRIBERS
Open an account at vending point.
Initialize user card.
Pre-purchase.
Write transaction data into user card.
TECHNICAL PARAMETERS

SPECIAL FEATURES
“One-card for four-meter” system: a single-phase watt-hour meter, a heat meter, a gas meter and a cold water meter.
“One-card for six-meter” system: a single-phase watt-hour meter, a heat meter, a gas meter, a cold water meter, a hot water meter, and a recycled water meter.
“One-card for eight-meter” system: two single-phase watt-hour meters, a heat meter, a gas meter, a cold water meter, a hot water meter, a recycled water meter and a purified water meter.
Electricity-vending management system: managing one or both of single-phase and three-phase watt-hour meters by the same system, determined by customers with a system card. The system card is also used for system registration. One or several managing cards are provided to enhance jurisdiction management of the system and for card recharging anddeletion of pre-purchase record. Logical encryption of system card and managing card ensures data security of the cards.
Water resource management system (heavy-duty water meter): for water user of large size pipe. To operate the system, one system card and one or several managing card(s) are needed. Functions of the two cards are same as that for Electricity Vending Management System.
Multi-tariff water meter management system: it manages water consumption by quota. Extra consumption above basic quota will be charged with higher step tariffs. Steps and step tariffs are set according to policy of management department, from one up to six steps and tariffs.
Heat meter management system: the system version V1.0 is for customers who installed prepayment heat meters. Heat consumption is charged on basis of basic fee plus consumption charge. Once a year heating management depart will collect a basic fee from each user based on area to be heated (m2). Consumption charge is based on heat volume user pre-purchased and heat tariff.
Total annual heat expenditure of user =
(Rate of basic fee * area heated)+ (heat tariff * heat volume pre-purchased)
