The invention discloses a built-in communication bin based on 230 MHz electric power wireless private network intelligent electric meter direct collection, and relates to a communication bin of an electric energy meter. At present, a built-in communication bin is mainly used for local communication, data needs to be forwarded to a service master station through a concentrator after being collected, the network structure is complex, more network devices are needed, the network security is poor, and the timeliness cannot be guaranteed. The built-in communication bin is arranged in an electric meter, and comprises a shell, an antenna module, and a main control unit, a power supply module, a communication module, a carrier module and a security chip module which are arranged in the shell; according to the technical scheme, through the 230 MHz electric power wireless private network, a concentrator does not need to be adopted for forwarding, the built-in communication bin is directly connected with a service master station, intermediate links are reduced, the data acquisition efficiency is improved, and a network structure is flattened; an annular recognition technology of the carrier communication and a wireless private network is adopted, the carrier interference is reduced through one-way carrier communication, and the data recognition rate is increased; and moreover, after carrier communication is completed, the module enters a dormant state, energy consumption is reduced, and line loss is reduced.
