specific Embodiment 1

[0063] Specific embodiment 1: as figure 1 as shown,

[0064] The invention discloses an intelligent anti-theft electric meter system, comprising:

[0065] The control unit 1 includes an intelligent controller, the intelligent controller includes an MCU, a display, and a keyboard, and the display and the keyboard are respectively connected to the MCU;

[0066] The anti-stealing unit 2 includes a transformer connected in series on the meter body, which is used to change a voltage different from the load operating voltage into the load operating voltage; a relay is provided at the output end of the transformer, and the control end of the relay is connected to the MCU ;

[0067] The voltage detection unit 3 includes two voltage sensors arranged on the primary and secondary sides of the transformer; the voltage sensor is electrically connected to the MCU, so that the MCU collects voltages on both sides of the transformer;

[0068] The voltage regulating unit 4 includes a voltage...

specific Embodiment 2

[0073] According to the intelligent anti-theft electric meter system of specific embodiment 1, its pressure measuring method:

[0074] (1) After the ammeter is connected to the power grid, the voltage sensor detects the voltage on the primary and secondary sides of the transformer at the same time;

[0075] (2) The MCU collects the analog voltage signal detected by the voltage sensor and converts it into a digital voltage signal for storage;

[0076] (3) At an interval of 60ms, the MCU collects, converts, and stores the voltage on the primary and secondary sides of the transformer again;

[0077] (4) After the MCU stores 8 digital voltage signals, the MCU extracts the stored digital voltage signals to calculate the average voltage, and at the same time calculates the maximum variation range of the voltage; if the maximum variation range of the voltage is not greater than the maximum variation range value pre-stored in the MCU, Then record the maximum variation range and avera...

specific Embodiment 3

[0081] According to the intelligent anti-theft electric meter system of specific embodiment 1, its voltage regulation method:

[0082] (1) The MCU detects through the voltage sensor that the voltage on the secondary side of the transformer is not equal to the working voltage of the load;

[0083] (2) The MCU controls the action of the voltage regulator, and then changes the coil connected to the circuit on the secondary side of the primary transformer; after 2-3s, the MCU detects and calculates the main adjustment difference between the voltage on the secondary side of the transformer and the operating voltage of the load;

[0084] (3) If the main adjustment difference is greater than the set value, repeat step (2) until the main adjustment difference is not greater than the set value

[0085] (4) After the main adjustment difference is less than the set value, the MCU controls the voltage regulator to change the coil connected to the circuit on the primary side of the transfo...

Abstract

The invention relates to an intelligent antitheft electric meter system, and belongs to the field of electrical equipment. The system comprises a control unit, an electricity stealing prevention unit, a voltage detection unit, a voltage regulation unit, an insect expelling unit, and a communication unit, wherein the electricity stealing prevention unit, the voltage detection unit, the voltage regulation unit, the insect expelling unit and the communication unit are respectively connected with the control unit. The system effectively avoids a phenomenon of electricity stealing. The phenomenon of electricity stealing is caused by that a user wants to save money and enables a household electric appliance or other loads to be connected to the input end of an electric meter. The phenomenon of electricity stealing not only reduces the safety of a power grid, but also causes hidden dangers to the personal safety. An MCU is used for unified control, so as to achieve the intelligent electricity stealing prevention of the electric meter. A display controlled by the MCU can display a detected voltage value and the detected electric energy consumption condition. The display can achieve a convenient query function and a control function through cooperating with a keyboard. A voltage detection unit can precisely detect the value of a voltage across two ends of a transformer, and prevents the difference between the output voltage of the transformer and the working voltage of the load from causing damages to equipment. The system achieves the constant output of a voltage.

Description

technical field [0001] The invention relates to an intelligent anti-theft electric meter system, which belongs to the field of electrical equipment. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. Current meter in use. The current coil inside the meter is short-circuited on the lead wire outside the meter to achieve the cheating effect of using electricity without running characters or less characters. This method of stealing electricity is very simple, that is, use a small section of wire outside the meter to short-circuit the two connectors of the meter to achieve the purpose. This method does not destroy the lead seal, the case, does not need to be connected to the open wire, and is easy to camouflage and emergency destruction, so it is adopted by many users. This is a ...
