將現(xiàn)行的供暖計費方式由按建筑面積計費變?yōu)榘聪牡臒崮苡嬞M是供暖計費方式發(fā)展趨勢，為了滿足這一計費方式變化的需要，設(shè)計了基于IC卡的預(yù)付費式新型供暖計費系統(tǒng)，通過測量用戶采暖系統(tǒng)進出口的溫度和流量，計算用戶消耗的熱能，利用IC卡記錄用戶預(yù)付費的金額和當(dāng)年熱能的單價，根據(jù)熱能消耗和當(dāng)年熱能的單價計算用戶采暖費，根據(jù)實際發(fā)生的供暖費用和預(yù)付費金額控制供暖的開停，這一計費方式的變化使供暖計費更趨合理。
Abstract:
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?蒺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?蒺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
