The invention discloses a no-address-mode micropower wireless centralized collecting method. The no-address-mode micropower wireless centralized collecting method overcomes the problem that a micropower wireless ad hoc network communication center node needs to downward send the address archive of a sub-node so as to establish a network tie. The method establishes correspondence between the address of a sub-node and the address of a 485 electric energy meter mounted at the sub-node and feeds the correspondence to a center node by reporting and network connection via a beacon frame broadcasting search list, expanded field intensity collection commands, expanded free nodes and the like, so the center node can carry out ad hoc network communication, data collection and other operations under the conditions of no downward sending of the address of the sub-node (a collector) and only sending of the address of the electric energy meter. Thus, the operation of making a correspondence table of the addresses of sub-nodes and the addresses of electric energy meters before network establishment is avoided; the error rate of networking is decreased; and acquisition of the data of the electric energy meters is smoothly carried out.
