智能热表的超低功耗设计

The Design of Intelligent Calorimeter with Ultra-low Power Consumption

按居住面积和供暖时间收取暖气费的方法暴露出的问题日趋明显,实行分户计量收费势在必行。作为分户计量的热表大都采取了干电池供电方式,要求干电池有效工作的时间越长越好,因而必需用特殊的方法使热表按超低功耗运行才能达到目的。本文阐述了一种超低功耗的智能化热表的设计思想。

The problems about the heating charge based on the area of the living space and the hearing period become clearer, and charging per household is inevitable. Mostly, the household-based calorimeter is battery powered, the life-span of the battery is as long as possible. Thus it is necessary to adopt some method to make the calorimeter featuring ultra-low power consumption. The design concept of such intelligent instrument is described and the major part of the prototype is analyzed in detail.
