The electric energy meter made by utilizing the method can effectively prevent electricity larceny modes such as changing the electric energy meter itself, as well as improving the property of electricity larceny prevention.
Description
Technical field
The present invention relates to a kind of intelligent electricity anti-theft method and electric energy meter thereof, belong to electric power meter and make the field.
Background technology
At present, the electricity anti-theft method of electronic electric energy meter has following several form usually:
Shunt+common measuring IC; Adopt μ Ω order of magnitude copper-manganese resistance to adopt the source, have the advantages that to prevent external short circuit, but can not satisfy the measuring requirement that the phase zero line is inverted input back output terminal " a fiery ground " as electric current;
Shunt+current transformer+two sampling measuring ICs; Shunt to the phase line current sample time current transformer neutral line current is sampled, have the accurate metering characteristics of being inverted input back output terminal " a fiery ground " at the phase zero line, but when zero line is fallen in input, can not satisfy the requirement that still can measure;
Shunt+current transformer+transducer+two sampling measuring ICs; Utilize transducer the principle of current transitions for the work required voltage, have when zero line is lost in input, still the characteristics that can measure are distorted the electric energy meter inner parameter and stealing but can not take precautions against when power down.
Above method all is at changing off-balancesheet stealing mode such as ammeter wiring, but can not prevent from effectively more electric energy meter itself such as to be changed at more and more hidden stealing mode.
Summary of the invention
The purpose of this invention is to provide a kind of intelligent electricity anti-theft method and electric energy meter thereof, improve existing stealing electricity method.All changes to electric energy meter itself all will cause moves or causes vibration, as long as artificially move or the vibration ammeter, just these behaviors can be noted as abnormal information behind use the present invention.
The object of the present invention is achieved like this: a kind of intelligent electricity anti-theft method, it is characterized in that: spatial triaxial directional acceleration sensor and microcontroller are set in ammeter inside, described microcontroller detects electric energy meter the moving or vibration signal in the spatial triaxial direction of sensing from three direction of principal axis acceleration transducers, send memory stores after the processing, send display device to show.
For realizing the present invention better, described microcontroller is set acceleration range and minimum threshold values, detection and electric energy meter the moving or vibration signal in the spatial triaxial direction of arriving from described spatial triaxial directional acceleration sensor sensing according to the condition filter of setting.
Intelligent electricity anti-theft electric energy meter of the present invention, comprise electric current, voltage sampling circuit, the metering special IC, display device, storer, the metering special IC receives from electric current, behind the sample rate current and sampled voltage that voltage sampling circuit provides, calculate the output electric pulse, it is characterized in that: also comprise microcontroller and spatial triaxial directional acceleration sensor, described microcontroller receives the electric pulse of described metering special IC and realizes function of measuring, control and receive moving or vibration signal of three shaft space directions that described spatial triaxial directional acceleration sensor sensing arrives simultaneously, this moves or vibration signal send described memory stores after described microcontroller is handled, and send described display device to show.
The invention has the beneficial effects as follows: after the electric energy meter installation, move again or the vibration ammeter as the external world, spatial triaxial directional acceleration sensor sensing goes out corresponding signal, by the microcontroller detection and according to behind the condition filter of setting, be recorded respectively and show, thereby prevent disguised extremely strong stealings such as mobile ammeter effectively, improved anti-electricity-theft performance.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is circuit theory diagrams of the present invention.
Among the figure: 1. voltage, current sampling circuit; IC1 is the metering special IC; IC2 is a microcontroller; IC3 is a spatial triaxial directional acceleration sensor; IC4 is a display device; IC5 is a storer.
Embodiment
The technical solution adopted in the present invention is: as shown in Figure 1, voltage, current sampling circuit 1 output sample rate current and sampled voltage send metering special IC IC1, metering special IC IC1 calculates and changes the electrical energy pulse of output power equivalent, the size of pulsed frequency is proportional to the sampled power size, deliver to the I/O mouth PA0 of microcontroller IC2 by the CF pin, realize the electric energy metrical function, and by information such as display device IC4 demonstration electric weight.After the ammeter installation, the output I/O mouth PA4 of microcontroller IC2, PA5, PA6 carries out acceleration range and the isoparametric setting of threshold values to spatial triaxial directional acceleration sensor IC 3, when moving or vibrate ammeter, spatial triaxial directional acceleration sensor IC 3 can be on X or Y or Z direction, produce the corresponding simulating voltage signal by acceleration induction, the input I/O mouth PA1 of microcontroller IC2, PA2, PA3 detect this 1 or to 3 signals by inner ADC analog to digital conversion, judge as threshold values greater than former setting, think that then ammeter is moved or vibrates, this abnormal information is by the output I/O mouth PA9 of microcontroller IC2, PA10, PA11 delivers to memory IC 5 storages, by output I/O mouth PA7, PA8 delivers to display device IC4 and shows; Why minimum threshold values will be set, it is the activity factor of considering ammeter institute installation environment, the normal vibrations that bring as heavy wagon flow, logistics carrying, house fitting-up, trace level earthquake etc., avoid too sensitive and write down insignificant information, guaranteed intelligent, thereby realize reliable anti-electricity-theft purpose; Memory IC 5 also can be built-in by microcontroller IC2 in the present embodiment.
