Background
Energy Monitoring System: refers to architecture and large of public buildings to install classification of consumption metering device, it is using the remote transmission of data by means of timely collection of energy consumption and achieve energy focused on building an online monitoring and dynamic analysis capabilities collectively, systems and software systems.
Core technology to optimize energy consumption monitoring is that, while optimizing the premise that accurate measurement of energy consumption and optimize the process of measuring energy consumption. Thus the “meter” in the traditional sense such a simple dataset evolved into “online data aggregation and control”, which the network has put forward higher requirements.
Firstly, it requires a speed for two-way Internet. Secondly, it requires flexible network architecture. Thirdly requires the network to accommodate enough nodes.
The figure is shown a typical network diagram:
For each building or independent internal WPAN can use wireless, PLC or Ethernet and wireless hybrid network approach. WPAN internal structure as shown below:
The following diagram acquisition node with the evolution of energy acquisition and control approach also has many forms, from the beginning of the public buildings and factories in the three type of the meter, to the following figure for home, office use collection receptacle and wireless lighting control, the increasingly more.
