Problems solved by technology

The advantage of broadcasting is that it has a wide range of objects, rapid transmission, diverse functions, and strong appeal; and because the broadcasting system is a multi-point arrangement, the wires of the broadcasting are mostly arranged in remote areas, which are easily struck by lightning and the equipment is easily damaged; in the past, broadcasting was mostly based on information content, The importance is controlled by manual switching. When an emergency occurs, it is difficult to transmit information, and it often takes a lot of time to start broadcasting, which affects the timeliness of information transmission. In case of emergency broadcasts such as geological disasters, there may be manual Unforeseen losses due to untimely switching or delayed switching

Description

technical field [0001] The invention relates to a control device for hierarchical automatic broadcasting of broadcast signals. Background technique [0002] Broadcasting refers to the information dissemination tool that transmits sound through radio waves or wires. Radio was born in the 1920s. The advantage of broadcasting is that it has a wide range of objects, rapid transmission, diverse functions, and strong appeal; and because the broadcasting system is a multi-point arrangement, the wires of the broadcasting are mostly arranged in remote areas, which are easily struck by lightning and the equipment is easily damaged; in the past, broadcasting was mostly based on information content, The importance is controlled by manual switching. When an emergency occurs, it is difficult to transmit information, and it often takes a lot of time to start broadcasting, which affects the timeliness of information transmission. In case of emergency broadcasts such as geological disasters...
