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 a power load data acquisition and management system for a plant. Electric quantity monitoring instruments are arranged on distributing lines of primary electric equipment andeach electric quantity monitoring instrument comprises one or more voltage transformers and current transformers. The electric quantity data acquired by the electric quantity monitoring instruments are transmitted to a centralizing processor to be processed through communication using a power line. The centralizing processor is accessed to the Internet through a network interface module, and management staff can use a computer and a portable mobile device to access a computer management system of a master station anytime.

Description

(1) Technical field: [0001] The invention relates to a factory power load data collection and management system, which includes a centralized monitor and various power monitoring instruments, and uses a power line communication method to send a wide pulse signal to a specific point where the grid cycle voltage crosses 0 to generate a sudden change current, so that the grid cycle carries information. . The centralized monitor receives the data collected by each power monitoring instrument, and connects to the Internet through the network interface module integrated with the TCP / IP hardware protocol stack, so that computers and handheld mobile devices can be used to access the remote computer management system. (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 wav...
