Anti-collision simplex communication system and method based on radio frequency energy collection tag chip

The invention discloses an anti-collision simplex communication system based on a radio frequency energy collection tag chip and an anti-collision method of the tag chip. The simplex communication system comprises a gateway and a radio frequency energy collection chip, and the gateway is used for providing charging and carrier modulation for the radio frequency energy collection tag chip, sending a name transmission code according to a set time for polling, collecting and processing data transmitted from the radio frequency energy collection tag chip, and interacting with an external network at the same time. Transmitting the data to a target terminal; and the radio frequency energy collection tag chip is used for collecting the charging energy sent by the gateway and modulating the carrier wave for charging, matching after receiving the name transfer code sent by the gateway, and sending the unique ID information of the chip to the gateway after matching the name transfer code. The uniqueness of the chip Id
