摘　　要：针对目前的取暖系统中所存在的计费方式不合理、浪费能源、用户选择空间小等诸多弊端,介绍一种基于MSP430FW423单片机的多功能取暖管理系统。阐述了利用MSP430FW423内部SCAN IF实现无磁流量检测的基本原理,以及利用其内部比较器构成SLOPE A/D转换器的方法,给出了热量计算的具体公式。本系统采用软硬件结合的方法,不仅实现了热量表所有的全部功能,而且实现了多种可供用户选择的取暖方式,成功地解决了目前取暖系统中的各种问题。In view of unreasonable questions existing in heat supply system such as the irrational charging means, the energy waste, much less options for users, a multifunctional heat supply management system based on the MSP430FW423 one-chip computer was introduced here. This article elaborated on the basic non-magnetic current capacity examination principle completed by using MSP430FW423 internal SCAN IF, as well as formulating the concrete way of heat calculation by means of its internal comparator constituted SLOPE A/D switch. This system adopted the combination of software and hardware, which not only realized the entire functions of calorimeter, but also provided a multialternation of heat supply for the users, as a result, many present questions in the heat supply system were successfully solved.
