The invention provides a rapid route recovering method in a wireless chain network. The method at least comprises one of the following two route recovering modes. A first route recovering model comprises following steps of when a moving node switches among different nodes, a target switching node is determined and the target switching node allows to switch the accessing moving node, after a source access node informs the moving node of switching permission, starting a route updating process, wherein the process comprises sub-steps S1 and S2, the sub-step S1 comprises that the source access node sends a route updating message to the target switching node instead of the moving node; and the sub-step S2 comprises that the target switching node reports a switching success message to the source access node and sends another route updating message to the source access node. The second route recovering mode comprises a following step of after the target switching node allows the moving node to switch, directly initi
