Visible wireless commanding device for mine rescure

Abstract

A mine rescue command visualization of wireless devices includes front-end equipment, repeater equipment, ground receiving equipment. Front-end equipment can capture filed picture under very low illuminance circumstances, and then audio signal and the parameters in the Underground sent to ground receiving equipment by way of repeater equipment, are downloaded and stored by ground operations center platform to achieve the dynamic of the scene underground surveillance and command. The invention's front-end equipment is an independent, full-featured, compact appearance of the micro-devices, adopting the most advanced Mesh wireless broadband network technology, using intelligent explosion-proof AP equipment for data transmission , the invention has real-time, accurate, multi-directional, multi-functional high speed and efficiency the advantages.

Description

technical field [0001] The invention relates to a wireless command device, in particular to a visualized wireless command device for mine rescue. Background technique [0002] When a disaster occurs in a mine, the ambulance personnel usually use a wired acoustic telephone or a special disaster relief telephone imported from abroad to rescue in the mine. Due to the special disaster environment, there is interference from flammable and explosive gases such as gas and gas that are harmful to the human body. Ambulance personnel must be equipped with self-protection equipment. Existing self-protection equipment generally uses negative pressure respirators or positive pressure respirators. If negative pressure respirators are used, the team members will breathe into the gas environment due to the nose clip falling off or opening their mouths, so they can only transmit the agreed information by the sound energy phone; Although the positive pressure respirator improves the comfort ...

AI Technical Summary

Problems solved by technology

Existing self-protection equipment generally uses negative pressure respirators or positive pressure respirators. If negative pressure respirators are used, the team members will breathe into the gas environment due to the nose clip falling off or opening their mouths, so they can only transmit the agreed information by the sound energy phone; Although the positive pressure respirator improves the comfort and safety of breathing and can speak, it is difficult to speak clearly due to the barrier effect of the mask

Therefore, regardless of using a wired acoustic phone or a wireless phone, it is impossible to clearly and accurately transmit various information such as sounds and images in the disaster area to reflect the actual situation in the disaster area.

At the same time, due to the flammable and explosive gas in the mine environment when a disaster occurs, the existing communication equipment with good performance cannot be used normally, which makes the accuracy and real-time performance of underground disaster relief voice communication poor, the amount of information is limited, and there is no memory, storage and image transmission functions.

When the accident happened, the existing communication and monitoring system in the coal mine could not be used safely and was basically in a paralyzed state

Some existing video and image devices need to use wired networks for transmission, but the laying of underground networks often takes a lot of time

These problems directly lead to poor information feedback between the rescue team and superior commanders and coordinators in the existing mine disaster relief equipment. The underground rescue personnel and the ground disaster relief headquarters cannot grasp the real situation in the disaster area in a timely and accurate manner. The inability to make scientific dispatch and quick response restricts its rescue work, delays possible rescue opportunities, and even causes greater disasters, causing greater casualties and property losses
