Abstract

The invention belongs to the technical field of electric energy measuring equipment, which relates to a multifunction watt-hour meter. A main control unit is used as a core part to be externally connected with a display unit, and is in electrical information communication with a communication unit; the main control unit is in electrical information communication with a keystroke handling unit to realize processing of keystroke information; a pulse output unit is electrically communicated with the main control unit according to an electricity principle; the main control unit is embedded with an electrical information-communicated storage unit, so that the storage management of data and information is realized; a measurement sampling unit and a power supply management unit are arranged on the periphery of the main control unit in an electrical communication way; and the units are in electrical information communication to combine into the multifunction watt-hour meter according to the electricity principle. The multifunction watt-hour meter has a simple structure, strong software portability, low cost, less power consumption, and high reliability, can realize remote meter reading and local communication, and is an ideal intelligent instrument for realizing electric energy measuring and business accounting operation.

Description

Technical field: [0001] The invention belongs to the technical field of electric energy metering equipment, and relates to a composite functional electric energy metering device with multi-parameter measurement, multi-communication modes and multi-tariff, in particular to a multifunctional electric energy meter. Background technique: [0002] Electric energy is the most important energy in today's society. With the continuous development of the economy, the power supply is becoming more and more tense. As the main tool for electric energy measurement, the electric energy meter has higher and higher requirements for its accurate, stable and reliable performance. At present, The development of energy meters with diversified design functions is gradually accelerating. The existing multi-function energy meters generally adopt the scheme of "dedicated energy metering chip + MCU" or "AD sampling + DSP + MCU", and its dedicated metering chip integrates ADC and DSP cores. Therefore,...
