Description
Technical field
The utility model relates to a kind of real recording electric energy meter in position of testing, and is a kind of electronic electric energy meter of liquid crystal display.
Background technology
Electricity is commodity, how much uses electric energy meter metering power consumption at present, and electric energy meter is installed in the service-wire front end usually, and the staff of electric system regularly copies the electric weight numerical value that shows on the electric energy meter, as the charge basis.Because the situation of electric energy meter registration often appears miscopying in manual metering, have no idea to find and miscopied, so influence the accurate metering of electric system, cause the dispute of electric system and electricity consumer easily to electricity consumer.
Summary of the invention
The purpose of this utility model provides a kind of real recording electric energy meter in position of testing, this electric energy meter can show the electric weight number and test the bit table registration, whether two groups of data can be power department and check manual metering correct, find that mistake is copied, the mistake problem of copying is provided convenience, thereby improve the accuracy of power department meterage.
The technical solution of the utility model is: a kind of real recording electric energy meter in position of testing, comprise watchcase, voltage changer is housed in the watchcase, power pack, electric energy computation chip, voltage to frequency converter, register, LCDs is housed on the watchcase, wherein voltage changer is connected with the electric energy computation chip input end respectively with power pack, the electric energy computation chip output terminal is connected with the voltage to frequency converter input end, it is characterized in that: register is by voltameter degree unit, the table number storage element, testing meter degree unit, position constitutes, voltameter degree unit, the table number storage element respectively with test a meter degree unit, position and be connected, the input end of voltameter degree unit is connected with the voltage to frequency converter output terminal, tests meter degree unit, position output terminal and is connected with LCDs.
This electric energy meter can show electric quantity data and test the bit table registration, store table number in the electric energy meter on LCDs.Because table number is input register internal fixation constant data, register draws through mathematical operation according to electric quantity data and table number data and tests bit data, so three groups of data are mathematical relations.Whether power department is correct with the relation of testing bit data with the electric quantity data that identical algorithm checks copies back, and just can find the electric quantity data that mistake is copied, mistake is copied, and reaches check, supervises the quality of checking meter, and improves the accuracy of meterage.
Description of drawings
Fig. 1 is a watchcase front view of testing the real recording electric energy meter in position.
Fig. 2 is an inner structure schematic diagram of testing the real recording electric energy meter in position.
Among the figure: 1 voltage changer, 2 power packs, 3 electric energy computation chips, 4 voltages, frequency converter, 5 registers, 6 table number storage elements, 7 are tested a meter degree unit, position, 8 LCDs, 9 voltameter degree unit, 10 watchcases, 11 and are tested bit table registration, 12 electric quantity datas.
Embodiment
The watchcase 10 of testing the real recording electric energy meter in position is provided with LCDs 8, voltage changer 1 and power pack 2 are housed in the watchcase, voltage changer is connected with electric energy computation chip 3 respectively with the output terminal of power pack, electric energy computation chip 3 and voltage, frequency converter 4 connects, register 5 is by voltameter degree unit 9, table number storage element 6, testing meter degree unit, position 7 constitutes, voltameter degree unit 9 and table number storage element 6 respectively with test a meter degree unit, position 7 and be connected, the input end and the voltage of voltameter degree unit 9, frequency converter 4 output terminals connect, and the signal output part of testing meter degree unit, position 7 is connected with LCDs 8.During use, voltage changer 1 and the power pack 2 input ends electrical network that inserts in parallel, during user power utilization, the high voltage of electrical network and big electric current have become electric energy computation chip 3 discernible signals through voltage changer 1 and power pack 2, and this signal passed to electric energy computation chip 3, electric energy computation chip is with voltage, current signal is handled, export one with a period of time in the voltage signal that is directly proportional of average power, again through superpotential, frequency converter 4 converts the correspondent frequency pulse signal to, and input register 5, register is a microprocessor, voltameter degree unit 9 goes out the electric weight number according to the frequency pulse calculated signals, test meter degree unit 7, position figure place is tested in one of the acquisition that performs mathematical calculations of gained electric weight number and table number number, again gained electric weight number is drawn electric quantity data 12 and tests bit table registration 11 with testing further processing of figure place, show by LCDs 8.
