With the development of science and technology, various electronic devices of the Internet of Things have gradually entered thousands of households. However, due to the different information transmission standards adopted by various manufacturers, the access methods of the Internet of Things are also varied, such as infrared, WiFi, Bluetooth, ZigBee, VB-IoT, LoRa, LTE and so on, which makes the market fall into chaos. In view of the above situation, In this paper, a communication technology of Internet of Things using PLC encryption transmission is proposed, By setting up the narrow-band exit of the Internet of Things with the Distribution station area as the unit, and using the existing resource "power line" as the communication carrier, the network signal covers all the power terminals, so that the IoT equipment can be connected to the network when powered on, thus realizing the unified monitoring and management of various items on the IoT cloud platform and reducing the construction cost of the IoT network.
Replacing coal with electricity is a national key livelihood project. In the field of energy conversion, the more electric heating is popularized in northern China, the less environmental pollution caused by loose coal in winter, and the more beneficial it will be to improve the quality of life of residents. Therefore, how to absorb these high-power green electric energy substitutes with little or no capacity increase in distribution network has become an urgent problem to be solved by State Grid Corporation of China. This paper puts forward an intelligent management technology that can make distribution transformers use clean electric heating in the form of over-capacity, On the premise of ensuring users' heating comfort, letting the distribution network accept more new electric heating load in the way of no capacity increase or less capacity increase on the existing basis will contribute to the wide promotion of electric heating and contribute to the early realization of "carbon peaking and carbon neutralization" in China.
