摘　　要：将现行的供暖计费方式由按建筑面积计费变为按消耗的热能计费是供暖计费方式发展趋势,为了满足这一计费方式变化的需要,设计了基于IC卡的预付费式新型供暖计费系统,通过测量用户采暖系统进出口的温度和流量,计算用户消耗的热能,利用IC卡记录用户预付费的金额和当年热能的单价,根据热能消耗和当年热能的单价计算用户采暖费,根据实际发生的供暖费用和预付费金额控制供暖的开停,这一计费方式的变化使供暖计费更趋合理。It is trend that the mode of heat charging is changed from billing by building area to by thermal energy. In order to meet the needs of heat charging mode changing, a new system of heat charging based on IC card is proposed. The user＇s energy consumption is calculated by measuring the user inlet and outlet temperature and flow,using the IC card to record the prepaid amount and the current price of heat. The user＇s heating costs is calculated according to energy consumption and current price, according to actual heating costs and prepaid amount,the system controls the heating opening or stopping. It is more reasonable that calculated heating costs by user heat consumption.
