摘要
以PIC16C73A微控制器为核心,采用软件滤波、低通滤波等技术,着眼于可靠性,设计了一种工业现场用温度智能仪表.该智能仪表可通过控制冷冻机冷却水流量对冷冻机蒸发温度进行控制,并且具有显示、报警等功能,可靠性强,易于升级,还可以应用于中央空调冷水机组.
Taking PIC16C73A micro controller as the core, with software filtrating and low-pass filtrating technology,taking reliability into account, design a kind of intelligent instrument operating in industrial environment. The intelligent instrument, with functions of display and alarm, can control the evaporation temperature of refrigerator by controlling its cooling water flow. It performances high reliability, easy to upgrade, and can be used in chillers in central air-conditioning.
