隨著國內(nèi)住宅業(yè)的迅速發(fā)展,熱量計在供暖行業(yè)的集中供熱和分戶計量中越來越重要
了。本儀表的二次儀表部分為低功耗單片機系統(tǒng),可以采用電池供電,極大地拓寬了熱量計的應(yīng)用范圍。在低功耗設(shè)計時,除了在硬件上選用低功耗的芯片,還在軟件上采用了低功耗設(shè)計技術(shù)。另外,本儀表還具有RS-485 接口,可以在相當遠的距離內(nèi)和上位機通訊,便于上位機采集數(shù)據(jù)。

Abstract: With the domestic housing developed quickly, it is more important in central heating and detached measurement of the heating industry. The signal processing circuit of the single-body calorimeter is a low-power micro-controller system, so it can be powered by lithium battery, which could widen its application range. In order to reduce power consumption, some low-power techniques are adopted in both hardware and software. In addition, the single-body calorimeter has RS-485 interface and can communicate with computer in quite far distance so that computer collects data.
