Embodiment
Through instantiation the present invention is further described below.
The wireless remote control stealing detection method that the present invention is based on intelligent electric energy meter is:
(1) in intelligent electric energy meter, increases a radio detection module, detect the wireless high-frequency signal of electric energy meter periphery.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, restore 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 intelligent electric energy meter is handled again;
(2) being connected like Fig. 2 of radio detection module and intelligent electric energy meter base table 1, wherein, 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;
(3) 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, and its process flow diagram is with reference to Fig. 3.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;
(4), when wireless remote control stealing incident takes place, initiatively this reporting events is arrived management of power use center for intelligent electric energy meter with 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.
