Additional apparatus for recording electric energy meter data and reducing energy consumption

Abstract

The invention relates to the technical field of the electric energy meter, especially to an additional apparatus for recording electric energy meter data and reducing energy consumption. The additional apparatus is composed of an infrared sampling circuit, a power management module, a metering module ADE7755, an MCU single-chip microcomputer, a standby battery, a 485 communication interface, and an infrared communication interface and the like. The infrared sampling circuit consists of an infrared photosensitive tube, a resistor, a capacitor, and a field-effect tube; and the power management module includes a transformer, a voltage-regulator tube, a diode, a capacitor, a resistor, and an integrated block and has three-path voltage outputs. The infrared sampling circuit and the power management module are respectively connected with the input terminal of the MCU single-chip microcomputer, the metering module ADE7755, the 485 communication interface, and the standby battery. According to the invention, the structure of the apparatus is simple; and the apparatus can be used conveniently and is suitable for electric energy meters with various types. The apparatus can be widely applied to the electricity larceny prevention field of the power system.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an additional device for recording electric energy meter data and reducing energy consumption. Background technique [0002] The safe and stable operation of the power system and the prerequisite for power market transactions are reliable and accurate power metering. The most commonly used electric energy metering methods in the prior art are inductive, electronic, and multi-functional all-electronic electric energy meters. However, these electric energy meters have single measurement functions, poor accuracy, and unsatisfactory anti-theft functions. For this reason, the anti-stealing electric energy meter with good precision has been developed continuously. For example, the Chinese patent number is Z200720115688.3 (a single-phase anti-stealing electric energy meter), anti-stealing electric energy meter and anti-stealing electric energy meter. These electric energ...

For example, the Chinese patent number is Z200720115688.3 (a single-phase anti-stealing electric energy meter), anti-stealing electric energy meter and anti-stealing electric energy meter. These electric energy meters have reasonable structure, reliable performance, sensitive response to any electric stealing, and can Unbalanced and other situations are measured and measured. The development of these electric energy meters has greatly improved the work efficiency of the electric power industry, making it impossible for some criminals to achieve the purpose of stealing electricity.

But its cost is high, energy consumption is high, operation is inconvenient, and the data cannot be copied and received by the handheld when the power is off.
