Problems solved by technology

However, due to the technical shortcomings brought about by simple modules, overall transplantation, and poor adaptability, resulting in poor communication effects, low accuracy, and poor reliability, and various products are affected by the site conditions of the installation building and the coverage of the on-site wireless communication network. The real-time strength of the real-time intensity has a great influence, and the phenomenon of false reporting, false reporting and mixed reporting has been continuously produced; it eventually leads to inconsistent meter reading data, transmission delays, information fluctuations, etc., which brings great troubles to electricity sales units and end customers. , resulting in a large number of conflicts and disputes between electricity sellers and electricity consumers
