The invention provides an intelligent helmet master controller and an intelligent helmet. The intelligent helmet master controller comprises a circuit board, a key part, a plurality of light sources, a Bluetooth sound box unit and a control unit. The circuit board comprises a first surface and a second surface opposite to the first surface; the key part is located on the first surface; the plurality of light sources are arranged on the first surface at intervals to form a light emitting band; the control unit is located on the circuit board, is connected with the key part, the light emitting band and a Bluetooth audio processor and is used for responding to the key part to control the light emitting band and the Bluetooth sound box unit. The intelligent helmet master controller provided by the invention can realize music playing, warning light emission and other functions and can be independent from the production of the helmet, and the main structure of the helmet body does not need to be changed, so that the production yield of the helmets is improved.
