description The invention provides a Zigbee equipment communication method and system based on beacon transmission and time slot allocation, and belongs to the technical field of Zigbee equipment communication. The problems existing in a Zigbee equipment communication method under the conditions of dense uplink periods, numerous terminals and high-frequency position mobile application scenes are solved; the technical scheme adopted for solving the technical problem is as follows: a Zigbee router registered to access a network through a server and a Zigbee gateway initiates routing discovery, the router submits path information step by step and establishes a routing chain table based on a B-tree data structure, and beacons are transmitted step by step in a determined path and a unique time slot through non-recursive preorder traversal on the B-tree chain table; the router receiving the beacon synchronizes self time information and sends the self time information to a next-level router specified by the routing chain table
