The invention relates to the technical field of
wireless communication of
the Internet of Things, in particular to a star communication method and
system of the building
Internet of Things based on
time sequence isolation, and the method comprises the steps: constructing a communication time axis of
radio frequency communication, dividing the communication time axis into a plurality of continuous communication cycles, and generating
time domain segmentation configuration information of each communication cycle; wherein the
time domain segmentation configuration information defines a
beacon time period, a control time period, a report time period and a synchronization time period which are arranged in sequence. According to the invention, a communication time axis based on strict
time sequence isolation is constructed, the
terminal equipment is forced to lock a reporting function in a control time period by issuing a time period control flag bit in a
beacon frame, the
exclusive access of a control instruction to channel resources is realized, the mechanism eliminates the interference of an uplink
data stream to a downlink control instruction, and the performance of the
terminal equipment is improved. Uncontrollable
delay in the prior art is reduced to deterministic time slot transmission, and the problem that in the prior art, the control success rate is low under high
concurrency is effectively solved.
