一种基于低功耗单片机的供热仪表系统开发

随着国内住宅业的迅速发展,热量计在供暖行业的集中供热和分户计量中越来越重要了。本仪表的二次仪表部分为低功耗单片机系统,可以采用电池供电,极大地拓宽了热量计的应用范围。在低功耗设计时,除了在硬件上选用低功耗的芯片,还在软件上采用了低功耗设计技术。另外,本仪表还具有RS-485接口,可以在相当远的距离内和上位机通讯,便于上位机采集数据。

The Calorimeter System Design based on Low Cost SoC

With the domestic housing developed quickly, it is more important in central heating and detached measurement of the heat- ing industry. The signal processing circuit of the single- body calorimeter is a low- power micro- controller system, so it can be pow- ered 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.
