The invention provides an advertising board for a subway and belongs to the field of culture media. The advertising board comprises a display screen, a first photoelectric detection unit, a first acoustic wave detection unit and a controller. The first photoelectric detection unit is arranged at the first position, a first distance away from an advertising board body, in the direction of a departure station of a subway train and is used for detecting the light intensity of the first position and sending a first photoelectric detection signal for indicating the light intensity of the first position; the first acoustic wave detection unit is used for detecting an acoustic wave signal of the first position and sending a first acoustic wave detection signal for indicating the acoustic wave signal of the first position; the controller is used for receiving the first photoelectric wave detection signal, judging whether or not the light intensity of the first position is larger than a first light intensity, if yes, starting the first acoustic wave detection unit, receiving the first acoustic wave detection signal, judging whether or not the loudness of the acoustic wave signal of the first position is larger than a first loudness, and if yes, starting the display screen.
Description
technical field [0001] The invention relates to the field of cultural media, in particular to a billboard for subways. Background technique [0002] The billboard is a signal tool for starting the next production process in the pulling system, or moving the work-in-progress to the downstream process.
