The invention belongs to the field of public audio-visual equipment control, and provides a control method and
system for one-key shutdown of public audio-visual equipment, which comprises the steps of initializing a
system, detecting the state of the public audio-visual equipment, receiving a one-key shutdown instruction input by a user, generating a corresponding
control signal according to the one-key shutdown instruction, and controlling the public audio-visual equipment according to the corresponding
control signal. The
control signal is sent to each protocol conversion device through a wired or
wireless communication module, and the protocol conversion device executes a power supply shutdown operation of the public audio-visual device after receiving the control
signal; according to the invention, through a one-key shutdown instruction, rapid and unified control of a plurality of public audio-visual devices is realized, the device
management efficiency is obviously improved, before shutdown operation is executed, a control
signal is transmitted through the communication module, the reliability of
signal transmission and the shutdown state of the devices are monitored in real time, and a manager can find and process abnormal conditions in time.
