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...
Currently, the information and communications technology (ICT) industry sector accounts for about 2–6% of the energy consumption worldwide, and a sign...
The single-carrier frequency division multiple access (SC-FDMA) system is a well-known system that has recently become a preferred choice for mobile u...
随着电磁阀在工业和日常应用的增多,其功耗越来越被人们所重视。通过对电磁阀驱动电路的研究,设计一套电磁阀节能驱动电路。不仅提高了电磁阀的响应时间,更重要的是降低了功耗,使电磁阀由工作在大电流状态下,变成大电流启动小电流维持的工作状态。减少了由电流过大引起的电磁阀线圈过热,增加了电磁阀的安全性。The ...
