摘要
由于实施分户热收费的迫切需要,详细介绍一种预付费式智能热量仪表的工作原理。根据供暖系统的技术指标,给出了硬件和软件系统的设计方法,能实现对温度、流量等各项参数进行分段自校正运算,提高了测量精度。从国外应用实例中分析了影响测量精度的主要因素并指出设计中应注意的问题。
Because of the urgent need of execution of divided family heat charging, working principle of one kind of prepaid fee type intelligent heat meter was introduced in detail. Base on the qualifications of heating system, design methodology of hardware and software were provided, which can improve the precision of measuring by proceeding automatic sectionalize adjuslment to parametes such as temperature and flow, etc. Factors that effecting the precision of measurement were analyzed in the instances of foreign countries, questions should be noticed in design were pointed out.
