集成电路毕业论文外文翻译

Since the electronic type electric energy meter from last centuries90 time rise in domestic shouldUse, now has more than 10 years of development history, but as a result of the technology, application of pushWide aspects, in the current market share is not high. Intelligent electricTable is based on this, in recent years before the development of practical function more richElectric energy meter, it has a series of advantages and functions, is the traditional induction meter can not beCompared to meters in the structure, principle and characteristicsPrincipleElectronic type intelligent electric meter, the electronic meter based on, in recent years the development ofLaunch high-tech products, its composition, working principle and the traditional inductive energyTable has the very big difference. Induction type meter is mainly composed of aluminum plate, current and voltage lineRing, permanent magnet and other elements, its working principle is mainly through the current coil andDynamic disks in induction vortex interaction for measurement. Electronic type intelligent electricTable is mainly composed of electronic components, its working principle is based on customer firstElectric voltage and current sampling in real time, and then use special electric energy meter IC, onSampling the voltage and current signals are processed and converted into electrical energy, and directly proportional to the pulseImpulse output, finally through the single chip to carry on processing, control, display for electric pulseQuantity and output. We usually get smart metering of electricity when the A / D converter byThe number of pulses called pulse constant, for intelligent electric meter, which is one less than theThe more important constant, because the A / D converter in unit time by the number of pulsesA how many, will directly decide the meter measuring accuracy. The intelligent meterMostly uses a A / D converter design principles, but also some manufacturersProduction of the multi-user centralized intelligent electric meter with multiple families sharing one A / D conversionDevice, so that the electric energy measurement can only use time-sharing queuing to, will cause the meterQuantity accuracy declines, it should pay attention to in design and type to the adoption of electronic integrated circuit design, coupled with a remote communicationFunction, can connect with computer and the software control, and therefore, inductiveTable, smart meter no matter whether in performance or function have a greatAdvantage.(1) power: due to the adoption of smart meters electronic components design, therefore aAs each power is only 016w ~017W left and right sides, for multi-user centralizedIntelligent electric meter, the average household power is smaller. While each inductionMeter power consumption is about 117w.(2) accuracy: Table error range,210 electric energy meter in5% ~ 400% calibration current range measurement error of + 2%, and the current generalAll applications are accurate grade 110 level, the error is smaller. Induction ammeterError range from + 186% to -517%, but due to mechanical wear thisTo overcome the defects, leading to the induction watthour meter walked more and more slowly, the final error more and moreLarge. The State Grid has the induction meter to undertake selectiving examination, the results found that more than 50%Induction type meter in use5 years later, the error will exceed the permissible range.(3), the frequency range of overload overload multiples: smart meters up to 6To 8 times, with a wide range of. At present 8to 10ratio table is more and moreMulti user choice, and some can even reach20rate in wide range. Working frequencyRate of wide, in the 40HZ ~ 1000HZ range. While induction meter overload timesCount as only 4 times, and the working frequency range is only 45~ 55HZ.(4): smart meters due to the use of electronic technology, can be achieved by phaseThe communication protocol with the computer networking, through software programming the hardwareControl and management. Therefore the intelligent meter not only has the characteristics of small size, but also with theRemote control ( remote meter reading, remote cutting-supplying electricity ), multi-rate, identification of malignant load, electricity anti-stealing electricity, prepaid expenses and other functions, and can pass on the control software ofWith the parameter modification, to meet the different requirements of control functions, and these functions onIn the traditional induction meter it is difficult or meter function applicationAccording to the design of some engineering examples, the different characteristics, different engineeringElectrical properties, different use place, how to reasonably choose different functional characteristics of intelligentMeter, make some of shallow discuss.分享到
