摘要
本文研制了一种以89C52单片机为核心构成的多功能智能电度表,对于节电节能具有重大的经济效益和社会效益,它同时具有电能表、无功补偿控制器和分时段电度表、串口通讯四种功能,并以LCD显示屏显示当前的功率因数、总电能值,可通过按键循环显示所消耗的峰、谷、平、总四个时段的电能值。
A multi-functional intelligent watt-hour meter that base on single chip computer 89c52 is researched. This research has significant economic benefits and social effect. The meter has four functions: kilowatt-hour meter, reactive power compensation controller, dividing time quantum and series communication. Power factor and total electric energy can be displayed on the screen of LCD. By pushing the button, the peak, valley, level and total electric energy can be displayed circularly.
