AI Technical Summary

Technical Problem

The existing mining damper system cannot trigger the switch normally due to the sensor being blocked by coal dust in harsh environments.

Method used

The mining damper opening system is adopted with dual condition trigger control of voiceprint and personnel/vehicle identification card. By installing card readers and sound pickup equipment on the tunnel walls and making comprehensive judgments through the electrical control box, the damper works normally in harsh environments.

Benefits of technology

It effectively avoids the problem that the damper cannot trigger the switch normally caused by the sensor in harsh environments, and ensures that the damper can operate reliably in a coal dust environment.

Abstract

The utility model relates to the technical field of mine air doors, in particular to a dual-condition trigger control mine air door opening system, which is characterized in that two side-by-side air doors are mounted in a roadway wall, and card readers and pickup equipment are mounted on two sides of the roadway wall on the outer sides of the air doors; card readers, pickup equipment and an electric cabinet are mounted on the wall of the roadway between the two air doors, and the electric cabinet is electrically connected with all the card readers and all the pickup equipment. The mining air door opening system has the advantages that the situation that a traditional sensor cannot normally trigger a switch when the air door is in a severe environment can be avoided through the mining air door opening system triggered and controlled under the double conditions of the voiceprint and the personnel / vehicle identification card.

Description

Technical Field

[0001] The utility model relates to the technical field of mine air doors, and particularly relates to a mine air door opening system controlled by dual conditions trigger. Background Technique

[0002] At present, most of the triggering methods for opening air doors on the market are triggered by infrared pair sensors, light control sensors, radar sensors, and video monitoring. When the light-sensitive position of the sensor, the infrared emission / reception position, the radar sensor antenna, and the video monitoring lens are blocked by coal dust, the air door cannot be triggered to open or close normally.

[0003] Therefore, this application designs a mine air door opening system controlled by dual conditions trigger of voiceprint and personnel / vehicle identification cards to solve the above problems. Summary of the Invention

[0004] The utility model provides a mine air door opening system controlled by dual conditions trigger to make up for the deficiencies in the prior art.

[0005] A mine air door opening system controlled by dual conditions trigger includes a roadway wall, and is characterized in that:

[0006] Two side-by-side air doors are installed in the roadway wall. A card reader and a sound pickup device are installed on both sides of the roadway wall outside the air door. A card reader, a sound pickup device and an electric control box are installed on the roadway wall between the two air doors. The electric control box is electrically connected to all the card readers and sound pickup devices.

[0007] Further, to better implement the utility model, one card reader is installed on one side of the roadway wall outside the air door, and one sound pickup device is installed on the other side.

[0008] Further, to better implement the utility model, one sound pickup device and two card readers are installed on the roadway wall between the two air doors, and the linear distance between the two card readers is greater than twice the card reading limit distance.

[0009] The beneficial effects of the utility model are:

[0010] The mine air door opening system controlled by dual conditions trigger of voiceprint and personnel / vehicle identification cards of the utility model can avoid the situation that the traditional sensor causes the air door to not be able to trigger the switch normally in a harsh environment.

[0013] In the figure,

[0014] 1. roadway wall, 2. air door, 3. card reader, 4. sound pickup device, 5. electric control box. Specific implementation manner

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Figure 1 - Figure 2 This is a specific embodiment of the present invention. This embodiment is a mine air door opening system with dual-condition trigger control. The sound pickup device and the personnel / vehicle identification card reader are installed at the air door inlet and between two air doors, and are connected to the air door electric control box through 485 control lines. The air door electric control box is connected to the underground industrial ring network through optical fibers, and the collected voiceprint data is uploaded to the password judgment module of the software platform for analysis.

[0018] Outside the air door, when the card reader detects a personnel / vehicle identification card signal for more than 5 seconds (the time is adjustable), it immediately sends signal A to the electric control box; when the sound pickup device receives the "open door" or "close door" (the switch password can be set) password, it uploads it to the password judgment database. Assuming that the "open door" password is B and the "close door" password is b, the air door electric control box verifies the current state of the air door. If the air door is currently closed + A + B, the air door opens; if the air door is currently open + A + B, the air door does not move; if the air door is currently closed + A + b, the air door does not move; if the air door is currently open + A + b, the air door closes.

[0019] Between the air doors, due to the small space, only 1 sound pickup device and 2 card readers can be installed. The card readers should be installed on the roadway walls on both sides respectively, and the linear distance is greater than 2 times the limit distance of the card reading signal. When the personnel / vehicle is within the signal range of the first card reader, the air door electric control box receives and judges the "open door" and "close door" passwords of the sound pickup device + the first card reader to control the first air door; when the personnel / vehicle is within the signal range of the second card reader, the air door electric control box receives and judges the "open door" and "close door" passwords of the sound pickup device + the second card reader to control the second air door.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
