Problems solved by technology

However, at present, this method often only has a voice communication system, and the ground processing personnel cannot directly see the situation in the mine, which may easily lead to misjudgment
In view of this problem, there is a technical proposal to add an additional image transmission system to send the downhole status information to the ground in time, but this requires additional setting of corresponding equipment, and the cost is relatively high

Embodiment Construction

[0025] Such as figure 1 As shown, the multi-band communication system for mine safety management of the present invention includes a voice communication subsystem, an image transmission subsystem, a sensor subsystem and a front-end machine arranged in a central station on the ground, and the three subsystems pass corresponding to the The interface equipment and interface software of each subsystem described above (for example, when the signal is transmitted through the voice communication subsystem, the interface equipment is a portable mobile phone or a vehicle-mounted station) changes the data of each equipment in the mine into a wireless signal, and the wireless signal is passed through The relay equipment in the base station installed in the mine sends to a transmission leaky cable shared by the above three subsystems, and further transmits to the central station on the ground through the transmission leaky cable, and then passes through the front end in the central station...

Abstract

The invention relates to a multi-frequency-band communication system for mine safety management. The multi-frequency-band communication system comprises a voice communication sub system, an image transmission sub system, a sensor sub system and a leakage system front-end machine; the three sub systems convert data of various equipment in a mine into wireless signals through interface equipment and interface software corresponding to the sub systems; and the wireless signals are sent to a transmission leakage cable commonly used by the three sub systems through relay equipment, are further transmitted to a central station on the ground through the transmission leakage cable, and then are processed via the front-end machine disposed in the central station, so real-time monitoring for a condition in the mine from the ground is achieved. The multi-frequency-band communication system for the mine safety management adopts the leakage cable to transmit information, the one transmission leakage cable is used to integrate the voice communication sub system, the image transmission sub system and the sensor sub system together, comprehensive real-time monitoring for the condition of the mine is achieved in low cost, and the safety factor of underground work is effectively improved.

Description

technical field [0001] The invention relates to a multi-band communication system, in particular to a multi-band communication system for mine safety management. Background technique [0002] At present, in the process of mining natural resources such as coal, operators are often required to go deep into underground mines to work. Due to the complex and harsh underground environment, there are many factors that endanger the personal safety of operators and mine construction safety. In order to avoid mine accidents, real-time monitoring of underground safety conditions is required. [0003] The current mine safety status detection mainly has the following methods: [0004] Professional safety personnel carry detection equipment deep into the mine for safety inspection, and report safety information through traditional telephone and other equipment. This method has a long history, mature technology, and low operating cost, but it requires a lot of manpower. , and rely heavil...
