Problems solved by technology

[0004] The detection of TW A CS signals is mainly based on time-domain difference technology. Most of these methods have complex data processing, poor real-time performance, and high equipment costs. In order to determine whether the signal bit is "1" or "0", due to the rigor of the calculation, the interference signal will seriously affect the judgment result of the detected signal, so the original method is difficult to apply in our country

Abstract

The invention relates to an electric energy measurement and automatic meter reading system for a residential area. A broad pulse signal is sent to a specific point of a cycle voltage 0-exceeding region of a power grid by utilizing a centralized controller and data acquisition units through a power line communication method, so as to generate mutation current; the mutation current is used as a bitvalue of the signal; data acquired by each data acquisition unit is received by the centralized controller and is accessed into a 4G mobile wireless communication network through a wireless router, sothat wireless networking can be realized by utilizing a mobile phone, a computer and handheld mobile equipment at any where.

Description

(1) Technical field: [0001] The invention relates to an automatic meter reading system for electric energy measurement in a residential area, which includes a centralized controller and a data collector, and uses a power line communication method to send a wide pulse signal to a specific point in the grid cycle voltage crossing 0 to generate a sudden change current, which is used as a bit of the signal. The centralized controller receives the data collected by each data collector, and accesses the 4G mobile wireless communication network through a wireless router, so that no matter where you are, you can use mobile phones, computers and handheld mobile devices to realize wireless networking. (two) background technology: [0002] Current power line communication mainly refers to power line carrier communication and two-way power frequency communication. Power line carrier communication PLC uses the existing power line to transmit signals through carrier wave. However, the di...
