Mine safety early warning and rescue information systems

Abstract

The present invention relates to a wireless information sending and receiving system, in particular to a wireless sending and receiving system for mine safety early warning and rescue information, including a main control computer, and at least one wireless information receiver connected in sequence with the main control computer Modulator, at least one power amplifier, and the same number of antennas as the power amplifier; wherein, the modulator is used for two-way communication with the main control computer, mutual data transmission, and data information sent by the main control computer coded, modulated into an ultra-long wave signal, and then output to a power amplifier, and then transmitted to the wireless information receiver through an antenna. The present invention has the prominent features of clear information, safety and timely, and easy to use. It can quickly establish an effective personnel dispatching and emergency rescue communication command method between the ground command center and underground miners, greatly improve the coal mine safety early warning capability, and promote the improvement of underground production efficiency and safety level.

Description

[technical field] [0001] The invention relates to a wireless information sending and receiving system, in particular to a wireless sending and receiving system for mine safety early warning and rescue information. [Background technique] [0002] With the increase of mining depth and the continuous extension of underground roadways, the threat of various disasters is increasing, and the difficulty of disaster management is increasing. It is manifested in the increasing amount of gas gushing out, increasing pressure on mines, and more complicated disaster management. my country's coal production accounts for 35% of the world's total, but the number of accident deaths has reached 80% of the world's total. The death rate of miners per 1 million tons of coal collected is about 100 times that of the United States and 30 times that of South Africa, ranking first in the world. From 2001 to 2004, an average of more than 10 mine accidents occurred every 7.4 days. In 2004, 6,027 peo...

Problems solved by technology

The disadvantage is: when there is an emergency underground, the system does not have the function of sending emergency response orders to the underground shift operators at the first time, and notifying the underground shift operation leaders to quickly organize the operators to implement emergency response measures or evacuate.

At present, there is no system for dispatching and commanding in normal production operations
