Method, device and system for data transmission based on ZigBee network

The invention discloses a method, a device and a system for data transmission based on a ZigBee network, relates to the field of data processing and solves a problem that lower success rate of data transmission is possibly caused when the ZigBee network affected by large disturbance is utilized to carry out data transmission in the existing technology. The method comprises the following steps that a first routing node obtains disturbing energy intensity of remaining channels when detecting that a current working channel is disturbed; the first routing node determines the channel whose disturbing energy intensity is smaller than a first threshold as a selectable switching channel; the first routing node sends a channel report message to an upper-layer routing node, wherein the channel report message comprises all selectable switching channels; the first routing node receives a channel switching message which is sent by the upper-layer routing node; and the first routing node is switched to a target switching c
