Problems solved by technology
[0002] With the development of science and technology, the electric power business has become an important part of the development of science and technology. People's basic life is inseparable from electric energy. Electricity metering is an indispensable link. At present, many places still use the traditional meter reading method, that is, door-to-door This method not only wastes a lot of manpower, but also is not conducive to data aggregation and data transmission, which is easy to cause data loss and confusion, which is very unfavorable to the development of modern electric power industry
