Problems solved by technology

[0003] At present, the number of electric energy meters used by urban residents and rural households is huge, about 150 million. The two major power grid companies have plans to build electricity information collection systems in the next few years, but a large number of consumer electric energy meters are due to cost. Considering the quantity and quantity, the power line carrier and short-distance wireless will be mainly used as the means of communication, and the communication signal of the carrier energy meter is transmitted on the power supply line together. Communication signals have a serious impact, resulting in great differences in communication signal performance, and it is difficult to determine the probability and intensity of interference. Before the purchase of carrier meters and the construction of power collection systems, it is difficult for power supply departments to have a prior understanding of the operating environment of electric meters. It is to use the manufacturer's carrier wave energy meter and electric energy
