Reconfigurable radio frequency energy collector for indoor distribution antenna monitoring system

The invention discloses a reconfigurable radio frequency energy collector for an indoor distribution antenna monitoring system. An N-stage reconfigurable rectifier and a voltage comparator are adopted, the framework of the N-stage reconfigurable rectifier can be adjusted according to the receiving power of an antenna, and the initial state is an N-stage Dixon rectifier series framework. And the voltage comparator compares the direct-current voltage signals output by the rectifiers, and adjusts the number of stages of the N-stage reconfigurable rectifiers and the series-parallel connection structure of the N-stage reconfigurable rectifiers according to the comparison result. According to the invention, the radio-frequency signal originally existing in the indoor distribution antenna system is creatively utilized, and the radio-frequency signal is used for energy collection and is used as a carrier signal for backscattering modulation. And the gateway end does not need to additionally add a radio frequency sign
