AI Technical Summary

Technical Problem

The existing underground voice broadcasting system in coal mines cannot broadcast messages according to personnel location, resulting in insufficient power supply and audio interference.

Method used

A zoned voice broadcasting system for the fully mechanized mining face is adopted, which includes a personnel positioning system, a voice broadcasting system, and a roadway centralized control system. The personnel positioning system obtains personnel location information, and the roadway centralized control system filters and converts it into audio signals, which are then sent to the electro-hydraulic control controller for targeted voice broadcasting.

Benefits of technology

It enables targeted voice broadcasts based on personnel location, reducing current consumption, minimizing audio interference, and improving the system's energy efficiency and broadcast accuracy.

Abstract

This invention provides a system and method for zoned voice broadcasting in fully mechanized mining faces, belonging to the field of personnel positioning and broadcasting technology in underground fully mechanized mining faces. It solves the problem of insufficient power supply or audio interference caused by existing underground voice broadcasting systems' inability to broadcast voice messages across the entire working face based on personnel location. The system includes a personnel positioning system, a voice broadcasting system, and a roadway control system installed underground. The personnel positioning system sends personnel location information to the roadway control system, which receives the personnel location information and converts it into the corresponding hydraulic support number. The roadway control system receives fault signals or important event signals from various underground subsystems, and through judgment or configuration, filters the signals from the working faces that need to be broadcast and converts them into audio signals. Then, based on the personnel location signals, it sends audio signals to electro-hydraulic controllers within a fixed range. This invention is applied to underground voice broadcasting.
