The invention provides an intelligent sensing voice broadcaster for equipment states, and belongs to the field of power transformation equipment. A controller is connected with a proximity detection module, a switch sensing module and an audio encoding and decoding module to realize processing and storage of signals of each module; the switch sensing module is connected to a knife switch of equipment, and the state change of the knife switch of each component is detected to realize accurate control of the working state of each component of the equipment, and the cold and hot standby states areeffectively identified; and after the controller receives that the proximity detection module detects that a human body approaches, the working state in a memory is called for encoding and decoding,the encoded and decoded working state is output to the audio encoding and decoding module, the encoded and decoded working state is converted into an audio signal, and the audio signal is output to asound box, so that an effective warning effect is achieved.
