Problems solved by technology

[0004] In view of the complex pilot site, there are not only the influence of power line load impedance fluctuations and noise signals from power interference sources, but also the shielding attenuation in dense obstacle areas such as urban buildings or mountains and metal spaces, and some station areas are often encountered. The lack of reply information for meter reading caused a lot of trouble for grid employees

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a general narrowband carrier and micropower wireless dual-mode communication module. Background technique [0002] Although the single micro-power wireless communication method has the function of realizing long-distance meter information collection, it can effectively solve the problem of inconvenient manual meter reading, no wiring, self-organizing network, intelligent frequency modulation selection, high communication rate, strong real-time performance and other advantages However, due to the complexity of the environment and region during the gradual installation and application process, some indicators of the interactive success rate of meter reading can no longer meet the requirements. [0003] Power line narrowband carrier communication is a traditional communication method. The carrier signal can transmit effective information through high-voltage ...
