Time distribution device and method based on time reversal in wireless power supply network

The invention belongs to the technical field of wireless energy transmission, and provides a time distribution device and method based on time reversal in a wireless power supply network. The device comprises a time grading module which divides the time period in the wireless power supply network into three stages; a downlink energy collection module which acquires energy from a radio frequency signal sent by a hybrid access point in a downlink energy transmission stage and stores the energy; a time reversal detection module which performs time reversal on a detected channel pulse response ina time reversal detection stage; an uplink information transmission module which performs uplink data transmission by using the obtained energy in an uplink information transmission stage; a time distribution module which performs time distribution by adopting a distribution mode corresponding to each stage. According to the method, the interference is suppressed by utilizing the special space-time focusing property of ti
