after the first device receives a network access confirmation frame sent by the intelligent device, determining the relative position information of the intelligent device relative to the first device;
and sending the relative position information of the intelligent device relative to the first device to other devices to update the relative position information of the first device relative to the intelligent device stored by the other devices, wherein the other devices are devices which are provided with UWB modules except the first device in the UWB network.
7. The method of claim 6, wherein determining the relative position relationship of the smart device with respect to the first device according to the sending time of the network acknowledgement frame and the receiving time of the network access acknowledgement frame comprises:
determining the interval duration of the sending time of the network confirmation frame and the receiving time of the network access confirmation frame;
and determining the relative distance information of the intelligent equipment relative to the first equipment according to the interval duration.
8. A network access apparatus for a smart device, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute the network access method for the smart device according to any one of claims 1 to 4 when executing the program instructions.
9. A network entry apparatus for a smart device, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute the network entry method for the smart device according to any one of claims 5 to 7 when executing the program instructions.
