Background

Energy consumption monitoring system: refers to the hardware system that realizes online monitoring and dynamic analysis functions of key building energy consumption by collecting classification and sub-item energy consumption metering devices for buildings and large public buildings, using remote transmission and other means to collect energy consumption data in time. A general term for a software system.

The core of energy monitoring technology is energy optimization, and the premise of optimization is accurate energy metering and measurement of energy consumption in the optimization process. This has evolved from a simple data set such as “sheet reading” in the traditional sense to “online data aggregation and control”, which puts higher demands on the network.

First, the network requires two-way speed. Second, a flexible network architecture is required. The third requirement is that the network can accommodate enough nodes.

The following figure is a typical network diagram:

Wireless, PLC or Ethernet and wireless hybrid networking can be used for each building or relatively independent WPAN. The structure inside the WPAN is shown below:

In the figure, the collection nodes evolved in the form of energy consumption collection and control. There are three forms from the first public buildings and factories and mines, to the collection sockets and wireless lights for home and office as shown below. The more you come.
