Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of intelligent ammeter, comprise voltage, current sampling unit, electric energy metrical special IC and chip microprocessor, the input end connection circuit of voltage, current sampling unit, output terminal is connected with chip microprocessor by the electric energy metrical special IC; Described chip microprocessor also is connected with far infrared communication interface, pilot lamp, output interface, LCDs, real-time clock, and is provided with parameter button is set.
The electric weight of electric system daily load curve peak period is called the peak electric weight, and the electric flux of low-valley interval becomes the paddy electric weight, and metering peak, the electric flux beyond the paddy period are called the ordinary telegram amount, and three's sum is total electric weight.
Adopt the intelligent ammeter of the utility model, the needs that can adapt to the peak valley tou power price, it can be by predetermined peak, paddy, the division of section at ordinary times, measure the power consumption of peak, low ebb, flat section respectively, thereby the power consumption to the different periods adopts different electricity prices, gives full play to the regulating action of electricity price, encourages the electricity consumption client to adjust power load, " peak load shifting ", rationally electrification resource.
Big electric current and outside 220V AC voltage conversion that electric current, voltage sampling circuit will flow through circuit are suitable little electric current, small voltage signal, through the pulse signal of computation chip circuit conversion one-tenth with variable power; Chip microprocessor carries out electric energy accumulative total after receiving pulsed power signal, and deposit in the storer, read clock signal simultaneously, according to pre-set period time-sharing measurement, and data are outputed in the display of ammeter and show, and the signal of communication that receives communication port at any time carries out data processing.At present existing many dedicated IC chips towards electric energy metrical, inside provide the relevant algorithm of a lot of meterings to realize, can the measured voltage/current effective value, power factor, active power, reactive power, meritorious energy, quadergy etc.
As shown in Figure 2, the line synoptic diagram of intelligent electric meter and data acquisition unit, intelligent ammeter is responsible for gathering user's consumption information such as electric weight, and data acquisition unit mainly is responsible for intensive data and is uploaded to Surveillance center.For the effective monitoring and the management that realize system, intelligent electric meter is not only finished the automatic gauge to resident's energy consumption, and has the long-range drawing lock function towards the defaulting subscriber.When finding that certain family is with arrearage and when acquiring a certain degree, system can produce control command by automatic or manual, and control command sent to data acquisition unit, after data acquisition unit receives control command, send control signal corresponding by its CPU again, after driving through light-coupled isolation and by chip for driving, the switching of pilot relay, open or cut off each user's general supply input, thereby realize power supply and outage control the user.
Electric energy W is active power P accumulation in time, promptly
W＝∫TPdt，P＝IU
Wherein T is integration time, so electric energy metrical can obtain by a series of computings such as integrations then by the measurement to electric current, voltage; The metering of active power is the active power of each phase, by to going electric current, voltage signal after the DC component to carry out obtaining after a series of digital signal processing such as multiplication, addition, digital filtering.
As shown in Figure 3, electronic electricity meter principle of work block diagram, electronic electricity meter grows up on the digital power meter basis, adopt the measurement of multiplier realization to electric power, measured high voltage u, big current i is delivered to multiplier after electric pressure converter and current converter conversion, multiplier is finished the voltage and current instantaneous value and is multiplied each other, export one with a period of time in the DC voltage U that is directly proportional of average power, and then utilize electric voltage/frequency converter, U is converted into corresponding pulsed frequency f, with this frequency division of the frequency, and the technology by a period of time inside counting device, corresponding electric energy shown.
