Enterprises such as steel and metallurgical plants have fast production pace, complex process flows, and close connections between upper and lower
processes. During production, they often need to communicate with relevant personnel, deal with emergencies, or control operations, which requires
high–quality communication and is suitable for extremely harsh conditions. Internal communication system for environmental conditions, taking the metallurgical plant as an example, industrial–grade intercom terminals are set up in each link of the steel production line to ensure that production line workers can communicate effectively and directly;
A visual dispatch station and communication telephones are set up in the electrical room as a command system to conduct unified management of the
production line intercom terminals. The intercom terminals can be connected to an external digital power amplifier to broadcast emergency broadcasts
