Method for triggering broadcast based on peripheral signals

The invention relates to the technical field of safety protection, in particular to a method for triggering broadcast based on peripheral signals. A trigger terminal obtains a trigger signal and arranges the trigger signal into a first data packet; converting the first data packet into a first voice packet, and transmitting the first voice packet outwards in a broadcast form; according to the invention, the trigger signal is received and generated by triggering the trigger button on the terminal, the trigger signal activates the trigger processing unit, the trigger processing unit arranges the trigger signal into the first data packet and sends the first data packet to the main control unit, and the main control unit synthesizes the corresponding voice information according to the content or property of the trigger signal. And the voice information is sent to the voice interphone module, and the voice interphone module immediately broadcasts the voice information to a nearby voice interphone, so that the func
