## Article

Energy consumption monitoring system: refers to a hardware system and a hardware system that implements online monitoring and dynamic analysis of energy consumption of key buildings by installing classified and sub-item energy consumption metering equipment for buildings and large public buildings, using long-distance transmission and other methods to collect energy consumption data in a timely manner. The general term for a software system.

The skill center of energy consumption monitoring lies in energy consumption optimization, and the conditions for optimization are accurate energy consumption measurement and measurement of energy consumption in the optimization process. In this way, the simple data collection such as "meter reading" in the traditional sense has evolved into "online data aggregation and control", which puts forward higher requirements for the network.

First and foremost, the two-way speed of the network is required. Second, agile network architecture is required. The third requirement is that the network can accommodate satisfying nodes.

The following figure is a typical network diagram:

For each building or relatively independent WPAN can use wireless, PLC or Ethernet and wireless hybrid networking methods. The internal structure of WPAN is shown in the following figure:

The network nodes in the figure also have various forms along with the evolution of energy consumption collection and control methods. From the initial public buildings and three meters in factories and mines, to the collection sockets and wireless light control for household and office use as shown in the figure below, more and more.

The center of metering in the whole system is the gateway node that has data aggregation and processing functions, and ensures the connection between PAN and WAN.

Now let's talk about the planning of the comment gateway.

design

The internal structure of the gateway node is as follows:
