Embodiment Construction

[0011] The present invention will be further described below by specific examples.

[0012] The wireless remote control electricity stealing detection method based on the smart electric energy meter of the present invention is:

[0013] (1) Add a wireless detection module to the smart energy meter to detect wireless high-frequency signals around the energy meter. The composition of the wireless detection module is as follows: figure 1 As shown, it is composed of a frequency-selective amplifier circuit, a detection circuit and a comparator. After the wireless signal passes through the frequency-selective amplifier circuit, the modulated signal is restored, and output to the detection circuit for demodulation, and then output high and low levels after passing through the comparator, and sent to the microprocessor of the smart energy meter for processing;

[0014] (2) The connection between the wireless detection module and the base meter 1 of the smart energy meter is as follo...

Abstract

The invention discloses a method and wireless detection module for detecting electricity stealing of a wireless remote control device. The method comprises the following steps of: arranging the wireless detection module in an intelligent electric energy meter, wherein the wireless detection module is composed of a selective frequency amplification circuit, a detection circuit and a comparator; judging if the electricity stealing of the wireless remote control device is existent in combination with change conditions of output and power of the wireless detection module; and recording electricity stealing start time, electricity stealing stop time, electric quantity and power at the start time and electric quantity and power at the stop time. Therefore, technical and data support is provided for electricity stealing prevention and electric quantity reclaiming of power supply enterprises.

Description

technical field [0001] The invention belongs to the technical field of electricity theft prevention, and relates to a detection method and a wireless detection module for a wireless remote control electricity theft of an intelligent electric energy meter. Background technique [0002] The smart energy meter has the characteristics of low power consumption and rich functions, and has adopted certain anti-theft measures. It stores a wealth of event records such as voltage loss, current loss, phase failure, and meter cover opening. It can realize timing freezing, instantaneous freezing, and agreed freezing, and can store load curve data for a long time. Retrospective power loss provides a favorable basis. [0003] However, with the development of electronics, communication and computer technology, the intelligence of electricity stealing technology has been continuously upgraded, and the behavior of using wireless remote control devices to steal electricity has appeared. The ...
