In order to explore the energy-saving control method of electronic communication, the author proposes the application of Internet of Things and embedded technology in electronic communication. The application makes full use of the “Internet of Things” and embedded technology to create an energy-saving system, send data to the energy-saving system to control the power supply, and control operation of electrical appliances to achieve energy saving results. According to the test resultsThe energy consumption of the system designed by the author after energy saving is 4.8335kWh, which is lower than that of the device before energy saving, which is 5.8424kWh and saves electricity. At different load current, the system output voltage is controlled at 220 V and the performance of the system is stable. ConclusionThe system designed according to the model proposed by the author has a good performance in terms of energy consumption and has a connection with Internet technology and embedded technology in fire communication power.
