Multifunctional watt-hour meter based on single chip microcomputer

Abstract

The invention discloses a multifunctional high-precision watt-hour meter which comprises a signal acquisition module used for acquiring a current signal and a voltage signal and sending the signals to a chip CS5463. The chip CS5463 detects the received current signal and voltage signal to obtain a detection digital signal and sends the detection digital signal to the single chip microcomputer; the single chip microcomputer controls the detection process of the chip CS5463, sends the received detection digital signal to an LED module and sends an abnormal detection signal to an alarm module; the LED module displays the received detection digital signal; the alarm module gives out an alarm after receiving the abnormal detection signal. The multifunctional watt-hour meter is high in cost performance and high in anti-interference capacity and measurement precision, and effectively eliminates deficiencies of an existing multifunctional watt-hour meter.

Description

technical field [0001] The invention relates to the field of measurement and detection, in particular to a multifunctional electric energy meter with a microprocessor as the core. Background technique [0002] A multi-function watt-hour meter refers to an watt-hour meter that has two or more functions such as time-sharing and demand measurement in addition to measuring active power (reactive power), and can display, store and output data. The traditional inductive watt-hour meter uses its structure and Restricted in principle, there are usually shortcomings such as small measurement range, poor stability, and low precision, which cannot meet the needs of social development. With the development and popularization of microelectronics technology and single-chip microcomputer, new intelligent measurement and control technology develops rapidly, so the electronic energy meter with single-chip microcomputer as the core shows its obvious advantages. Contents of the invention ...
