The Promotion And Application Of Digital Anti-noise Explosion-proof Loudspeaker Intercom Telephone Stations

Many industrial sites, such as oil and chemical enterprises, thermal power plants, coal preparation plants, steel mills and port terminals, etc., have industry characteristics such as harsh working environments (high noise, high dust, high humidity) and high staff mobility. To effectively address the communication issues with the production characteristics of such industries, the traditional dispatching communication system (without anti-noise broadcasting function) can no longer meet the production demands of enterprises. This provides a stable and reliable market platform for the promotion and application of anti-noise broadcasting call systems. Some industrial and mining enterprises have equipped their staff with wireless walkie-talkies to solve the communication problems of mobile personnel. However, some job positions have a shielding effect on wireless signals; In addition, in a high-noise environment, the call quality of using walkie-talkies is already very poor. Therefore, the communication effect of using walkie-talkies in such a working environment can be imagined. The anti-noise broadcast call system is a wired communication system, featuring no signal blind spots, excellent call quality and rich functions, which cannot be replaced by wireless intercom communication. In order to enhance the level of automated production and save energy and increase efficiency, all newly-built industrial and mining enterprises have designed and installed centralized monitoring systems. All the industrial and mining enterprises that have been put into operation and production are also undergoing centralized monitoring and transformation. Since the centralized monitoring system can output various "prompt/alarm sounds" of the operation status of production equipment, in order to ensure safe production and production efficiency, it is necessary to provide on-site staff with "prompt/alarm sounds" of the operation status of production equipment. This provides new practical efficiency for the promotion of the anti-noise broadcast call system.
