The digital DC power supply from the analog power, display circuit, control circuit, digitaltoanalog conversion circuit, regulator circuit and analogtodigital converter circuit posed of six parts. This system is based on the principle of singlechip microputer to control the unit AT89C51 to DAC0832 digitaltoanalog converter chip reference voltage to control the output voltage, while the analogtodigital converter ADC0832 chip convert the sampling of voltage to digital signals. Analog power supply to provide the various chips, digital amplifier control and the required operating voltage, display circuit for displaying the size of power supply output voltage, output voltage value may be stepping through the control button (177。 super vision Sur vey Sect ion r elies on m otor vehicle det ect ion r emot e issued t est qualif ied logo sof t war e plat for m super vision m otor vehicle t est , and ident if icat ion sit uation 7418l iangci, invest igat ion m otor vehicle except ion business 30 car t im es, his par ds business war ning 244 ar t icle, vehicles and dr iving people sound video r egulat or y screenshot s 1852 Zhang, checks m otor vehicle ar chives 716 pieces t imes, and medium bus, and medium above t r uck, and Of hazar dous chemicals, vehicles and school buses and other key vehicle inspect ion r ecord of 420.
