A data acquisition and management system for power consumption of factories, mines and enterprises

Abstract

The invention relates to a power consumption data acquisition management system of a factory, a mine and an enterprise, wherein each group of power consumption equipment is provided with an electric quantity collector to collect power consumption information of a plurality of power consumption equipment, and each power consumption equipment is provided with a voltage transformer and a current transformer. The current and voltage signals collected by the electric quantity collector are conditioned and amplified and sent to the A / D converter for various electric energy calculation, and uploadedto the centralized controller through power line communication, and then integrated by the centralized controller through the network interface module integrated with TCP / IP hardware protocol stack toaccess the Internet, so that the remote computer management system can be accessed by the computer and handheld mobile devices.

Description

(1) Technical field: [0001] The invention relates to a power consumption data collection and management system for factories and mines, which includes a centralized controller and various power collectors, and uses a power line communication method to send a wide pulse signal to a specific point where the cycle voltage of the power grid passes through 0 to generate a sudden change current, so that the cycle of the power grid can carry information. The centralized controller receives the data collected by each electricity collector, 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 ...

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
