The utility model content
The purpose of this utility model is that the purpose of this utility model provides and a kind ofly compares in real time with electrical impulse frequency data and standard electricity consumption electric current in real time by reading in the ammeter extension line, can test at the scene that timely discovery stealing etc. is unusual in time sends signal to ammeter copy system far away, so that the timely anti-electricity-theft real-time supervisory device of digital kilowatt-hour meter of evidence obtaining of supervision of power consumption personnel.
For reaching above-mentioned purpose, technical solution adopted in the utility model is to it is characterized in that comprising: card table, electric current voltage transitions, pulse detector, frequency meter, frequency voltage transitions, single-chip microcomputer, power amplifier, red light, green light, wireless transmitting unit, radio receiving unit, dop, pulse induction probe, switch.Dop links to each other with the card table, and Ka Biao links to each other with the electric current voltage transitions, and the electric current voltage transitions links to each other with single-chip microcomputer by K switch, and single-chip microcomputer connects power amplifier, red light, green light, and the other end of power amplifier connects wireless transmitting unit; Pulse induction probe links to each other with pulse detector, and pulse detector links to each other with frequency meter, frequency meter and frequency voltage transitions link to each other, power amplifier links to each other with wireless transmitting unit, the signal that radio receiving unit sends for the reception wireless transmitting unit.
The utility model provides a kind of digital kilowatt-hour meter anti-electricity-theft real-time supervisory device for transmission line of electricity anti-theft electricity technology field.Its principal feature is, comprise, card table, electric current voltage transitions, pulse detector, frequency meter, frequency voltage transitions, single-chip microcomputer, power amplifier, red light, green light, wireless transmitting unit, radio receiving unit, dop, pulse induction probe, switch.Electric power supervision of power consumption department is for the electricity filching behavior of modern high tech method, all will spend the regular hour every year, energy hits electricity filching behavior, there is certain corresponding relation in normal watt-hour meter extension line current value size with the flicker frequency of digital kilowatt-hour meter operation pulsed illumination pipe, when the electricity consumption electric current is large, the flicker frequency of digital kilowatt-hour meter operation luminotron is just high, otherwise frequency is just low, when watt-hour meter extension line current value and the flicker frequency corresponding relation of operation pulsed illumination pipe were destroyed, this device can in time find to rewrite the ammeter chip program, the high-tech electricity filching behavior of data.And in time send the stealing signal to copy system far away, the power supply personnel evidence obtaining of can filing has timely strengthened the hitting dynamics to electricity filching behavior, effectively hits electricity filching behavior.Compared with prior art have: can in time find electricity filching behavior, the generation of thoroughly stopping the stealing event uses manpower and material resources sparingly, and is safe and reliable waits remarkable advantage.
Description of drawings
Reach by reference to the accompanying drawings example and further specify specific structural features of the present utility model.
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Referring to Fig. 1, the anti-electricity-theft real-time supervisory device of a kind of digital kilowatt-hour meter described in the utility model.Its principal feature is to comprise: card table 1, electric current voltage transitions 2, pulse detector 3, frequency meter 4, frequency voltage transitions 5, single-chip microcomputer 6, power amplifier 7, red light 8, green light 9, wireless transmitting unit 10, radio receiving unit 11, dop 12, pulse induction probe 13, switch K.Dop 12 links to each other with card table 1, card table 1 and electric current voltage transitions 2 link to each other, electric current voltage transitions 2 link to each other with single-chip microcomputer 6 by K switch, single-chip microcomputer 6 connects power amplifiers 7, red light 8, green light 9, the other end of power amplifier 7 connects wireless transmitting unit 10; Pulse induction probe 13 links to each other with pulse detector 3, pulse detector 3 links to each other with frequency meter 4, frequency meter 4 and frequency voltage transitions 5 link to each other, power amplifier 7 links to each other with wireless transmitting unit 10, and radio receiving unit 11 is used for receiving the signal that wireless transmitting unit 10 is sent.
Its principle of work is: open dop 12 during use, the outlet of watt-hour meter is put into wherein, can record watt-hour meter outlet wire current value 1, convert corresponding voltage signal to through Guo Dianliu voltage transitions 2, through divider resistance R1, R2, R3 ... Rn is divided into different voltage, switch K is according to the model of digital kilowatt-hour meter, and watt level is such as 2(4) A, 3(6) A, 5(10) A selects different gear input single-chip microcomputers 6.
