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

Embodiment Construction

[0011] The present invention will be further elaborated below according to the drawings and specific embodiments.

[0012] The design mechanism of the Mine Safety Early Warning and Rescue Information System (Mine Emergency System, MES) described in the present invention is to apply the ultra-long wave wireless communication technology in the coal mine underground, and the ultra-long wave wireless signal can be diffracted and penetrated in the complex environment of the underground roadway. The transmission characteristics of the coal (rock) layer realize the mobile transmission and communication of the wireless signal in the underground roadway.

[0013] As shown in Figure 1, the system of the present invention includes: a main control computer 1, a plurality of wireless information receivers 5, a modulator 2 connected in sequence with the main control computer 1, at least one power amplifier 3, at least one loop antenna 4, and Antenna lightning protection safety protection de...

Abstract

The invention relates to a wireless information sending and receiving system, in particular to a wireless system for sending and receiving mine safe alarming and rescue information, comprising at least a wireless information receiver, a modulator series connected with the master control computer, at least a power amplifier and antennas with the same number with the power amplifiers, wherein the modulator is used for two-way communication and transmitting data to each other with the master control computer and codes the data information from the master control computer, and then modulates the data to a myriametric wave and outputs to the power amplifier, and the myriametric wave is transmitted to the wireless information receiver via the antenna. The invention has the advantages of clear information, safe and timely, simple in using, and can rapidly build a communication and controlling method between a ground control center and underground miner's hammers for personnel dispatching and emergency rescuing, therefore improves the safe alarming property in the mine and enhances the production efficiency and security level underground.

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...
