The invention discloses an airplane passenger cabin data emitting system. The system comprises at least one data emitter, wherein the data emitter comprises a switch, a server and a wireless AP module; the wireless AP module and the server are both connected with the switch; the switch is connected with external network equipment; and the wireless AP module is in communication connection with an external mobile terminal. The airplane passenger cabin data emitting system provided by the invention has the advantages that the switch, the server, the wireless AP module and a power module are integrated, so that a small size and a large capacity are achieved, and a passenger, without connection to an external network, can access internal data of the server by establishing access of a handheld mobile terminal to wireless signals; and compared with the prior art, the system achieves entertainments through the mobile terminal without adoption of the traditional in-flight entertainment system, in which AVOD service is provided through hanging televisions or display screens mounted on chair backs, so that the costs for an airplane passenger cabin entertainment system are reduced, and the passenger experience for the passenger cabin entertainment system is improved.
