Description
Technical field
The invention belongs to the anti-theft electricity technology field, relate to a kind of electric energy meter that can detect the wireless remote control stealing.
Background technology
Intelligent electric energy meter has that oneself power consumption is low, the characteristic of feature richness, and has taked certain measures of anti-stealing electricity.Abundant logout contents such as its storage decompression, defluidization, the phase failure, game clock lid; Can realize regularly freezing, instantaneously freeze, arrange to freeze; Can store the load curve data of long period, for power department is discovered and seized electricity filching behavior, reviewed electric quantity loss favourable foundation is provided.
Yet along with electronics, communication and development of computer, the intelligent constantly upgrading of stealing technology has occurred utilizing wireless remote controller to steal the behavior of electric weight.This wireless remote controller is made up of transmitting terminal and receiving end.Receiving end is installed in the voltage circuit or current return of electric energy meter snugly.Transmitting terminal sends signal, and receiving end is according to the break-make of its place branch road of the signal controlling that receives, and voltage through changing actual metered or current value reach the few meter or the purpose of quantity calculation not.This method has disguise, and the inspector of electric power enterprise is difficult to find and evidence obtaining.Though have the rich data record to be used for analyzing whether there is unusual electricity consumption in the intelligent electric energy meter, can't detect the behavior that utilizes wireless remote controller to steal electric weight automatically.
The utility model content
The purpose of the utility model is to provide a kind of electric energy meter that can detect the wireless remote control stealing, and this electric energy meter can detect the behavior of wireless remote controller stealing, finds the unusual electricity consumption of user in real time.
This electric energy meter that can detect the wireless remote control stealing provided by the invention comprises base table; Also comprise a radio detection module; The power supply of this radio detection module and ground connection are provided by the electric power system unit of said base table; The output of radio detection module connects the microprocessor of said base table, and the high-frequency signal that detection is received send microprocessor analysis, and power then is judged as wireless remote control stealing incident as descending saltus step takes place.
Said radio detection module is made up of selective frequency amplifier circuit, detecting circuit and comparer; Wherein selective frequency amplifier circuit is reduced into modulated signal with wireless signal; And export detecting circuit to and carry out demodulation, by comparer output high-low level, the microprocessor that is sent to said base table is handled.
The utility model is actually in existing intelligent electric energy meter has increased a radio detection module; Can effectively detect to utilizing wireless remote controller to steal the behavior of electric weight, in case note abnormalities then produce warning message, recording events data; Particularly to the intelligent electric energy meter with GPRS module is arranged; When detecting the wireless remote control incident, can also initiatively this reporting events be arrived management of power use center, can contain the bad behavior of illegal electricity consumption; Safeguard the legitimate rights and interests of power supply enterprise, reduce the energy loss of country.
Description of drawings
Fig. 1 is the structural representation of the utility model electric energy meter.
Fig. 2 is a radio detection module composition frame chart.Among the figure, 1 is base table, the 2,3, the 4th, and the interface of radio detection module and base table is respectively warning output, power supply and ground.
Embodiment
Through instantiation the utility model is further described below.
As can beappreciated from fig. 1 the utility model electric energy meter has base table 1 and radio detection module, and wherein base table 1 base table 1 comprises microprocessor, storage unit, clock, electric energy metrical unit, electric power system unit, I/O unit and communication unit etc.Base table and radio detection module adopt three-wire interface to link to each other, being respectively reports to the police exports 2, power supply 3,4.Wherein, power supply 3 provides with the 4 electric power system unit by base table 1, ground, and the output 2 of reporting to the police is connected to the microprocessor of base table 1.
The as can beappreciated from fig. 2 structure of radio detection module, the composition of this radio detection module is as shown in Figure 1, is made up of selective frequency amplifier circuit, detecting circuit and comparer.Wireless signal via selective frequency amplifier circuit after, be reduced into modulated signal, and export detecting circuit to and carry out demodulation, via exporting high-low level behind the comparer, the microprocessor that is sent to base table is handled again.
Base table 1 when microprocessor is carried out metering, measurement, event recording function, periodically detects the behavior that whether has the wireless remote controller stealing in operational process.Microprocessor judges whether to exist wireless signal to report to the police according to the warning output 2 of radio detection module.Report to the police if exist, whether the power of further analyzing electric energy meter significantly saltus step has taken place.If the descending saltus step of power, microprocessor is judged as the behavior that utilizes the wireless remote controller stealing with this situation, and the moment, electric weight and power take place record; Report to the police if receive wireless signal, but saltus step does not take place in power, then think the high-frequency signal that has nothing to do, do not handle; If wireless remote control stealing incident has taken place, and the ascending recovery of power, then being judged as the wireless remote control incident and finishing, it is normal that electricity consumption recovers, the end of record (EOR) moment, electric weight and power.Because power is directly proportional with voltage and current, in practical application, can be installed in position (voltage circuit or the current return) difference in the ammeter, with voltage or electric current replacement power, as the basis for estimation whether stealing takes place according to the remote control electricity filching device.For example, the remote control electricity filching device is installed in the electric energy meter of current return, when receiving that wireless signal is reported to the police and during the descending saltus step of electric current, this situation is judged as the behavior that the wireless remote controller stealing takes place; When wireless remote control stealing incident and electric current taking place, then be judged as the wireless remote control incident and finish by little big to recovering.
Therefore whether whether the utility model can detect the wireless high-frequency signal and exist, have wireless remote control to steal electrical phenomena thereby accurately analyze.Can contain effectively that thus wireless remote control steals the generation of electric incident.Particularly, when wireless remote control stealing incident takes place, initiatively this reporting events is arrived management of power use center to having the intelligent electric energy meter of wireless communication module.Electric power enterprise also can report to the police or trip signal electric energy meter output sound, light when detecting stealing according to its individual character requirement, has greatly made things convenient for effective management of power department.
