The system can be divided into three layers: the field device layer, the network communication layer and the platform management layer.

Field equipment layer: It is mainly connected to various types of instruments used in the network for the acquisition and measurement of water, electricity, gas and other parameters, and is also a necessary basic element for constructing the power distribution, water consumption, and gas consumption system. With the heavy responsibility of collecting data, these devices can be the company's various series of power meters with communication network, temperature and humidity controllers, switching value monitoring modules, as well as water meters, gas meters, and heat and cold meters from qualified suppliers.

Network communication layer: including on-site intelligent gateways, network switches and other equipment. The intelligent gateway actively collects the data of the field device layer equipment, and can perform protocol conversion, data storage, and upload the data to the established database server through the network. The intelligent gateway can store the data locally when the network fails. Continue uploading data from the interrupted position to ensure that server-side data is not lost.
