Taking into account the actual requirements and characteristics of the broadcasting system of the mine, and considering the advancement, reliability and economy of the equipment, the network audio broadcasting system is selected, and different broadcasting implementations are designed according to different areas of the enterprise and different broadcasting function requirements. In the end, the main broadcast control room controls and broadcasts the entire enterprise broadcast system through the IP data network platform according to the different broadcast needs of each region and each time period of the enterprise.
Each district uses the network terminal and explosion-proof speakers to broadcast background music. The advantages are:
1. The network signal can be converted into an analog signal to enter the traditional broadcasting power amplifier to meet the needs of broadcasting;
2. It can be controlled uniformly by the broadcast master control room, and can be independently controlled locally as a subsystem;
