Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a meter reading system, a meter reading method and a meter reading device. Background technique [0002] At present, there are mainly single-carrier meter reading systems and micro-power wireless meter reading systems for residential electricity information collection. However, in the process of using the above two systems, some sporadic islands are far away from other parts or are seriously interfered, the wireless signal is difficult to cover and the carrier is affected by the impedance change of the power line, noise and harmonics. There are also some user tables located in the basement, and the carrier and wireless signals are also difficult to cover. In addition, there are a small number of unreadable tables and tables whose copying is very unstable. The current single-carrier meter reading system and the micro-power wireless meter reading system are unstable. The cur...
