Problems solved by technology

However, the existing real-time monitoring and forecasting methods of rock burst (including microseismic, acoustic emission, electromagnetic radiation, infrared radiation, etc.) have a high rate of false alarms and false negatives, which is difficult to meet the needs of coal mine safety production.
[0004] The mining working face in the coal mine is prone to rock burst. When the rock burst occurs, it is easy to cause the staff near the working face to be buried or trapped; in addition, the rock burst will cause the blockage of the roadway near the working face, making the roadway Poor ventilation causes gas accumulation, which can easily lead to gas explosion

Embodiment approach 1

[0039] like image 3 The system shown mainly includes:

[0040] 1. Video recognition server (301). The video recognition server is responsible for processing the video images of various cameras, and sends out alarm and power-off locking signals by analyzing data changes and fault information.

[0041] 2. Monitoring host (302); with sound and light alarm function, production management personnel can view live video images, sensor data changes and equipment failures through the monitoring host, and can manually send out alarms and power-off locking signals to cut off all non-intrinsically safe underground coal mines. Power supply of electrical equipment, issue a dispatch order to notify the withdrawal of underground coal mine operators. And can retrieve historical monitoring data from the storage server.

[0042] 3. Storage server (303); responsible for collecting and storing camera signals, various sensor signals and equipment failure signals, and providing query and retrieva...

Embodiment approach 2

[0055] like Figure 5 The system shown mainly includes:

[0056] 1. Storage server (501); responsible for collecting and storing video signals, alarm signals, methane sensor signals and equipment working conditions, and providing query and retrieval services for users.

[0057] 2. Monitoring host (502); with sound and light alarm function, production managers can view live video images, alarm conditions, methane sensor data and equipment conditions through the monitoring host, and can manually send out alarm and power-off locking signals to cut off all abnormal Intrinsically safe electrical equipment power supply, issued a dispatch order to notify the withdrawal of underground coal mine workers. And can retrieve historical monitoring data from the storage server.

[0058] 3. Monitoring the standby machine (503); when the monitoring host breaks down, work is performed through the monitoring standby machine.

[0059] 4. Network switch (504); responsible for the management and...

Abstract

The invention discloses an impact ground pressure alarm method based on an image recognition acceleration characteristic. The alarm method comprises the following steps of mounting a camera near a related area of an excavating working face; analyzing video image data change and equipment working condition in real time to find abnormal data change in a monitored area; and if an abnormal combinationcondition of information meets an alarm condition, sending out an impact ground pressure alarm signal. The alarm method fully considers various characteristic points of the impact ground pressure ofthe excavating working face of a coal mine, is easy to implement and can judge the impact ground pressure of the excavating working face relatively accurately, so that the rescue efficiency is improved effectively, it is favorable for management staff to take corresponding measures in time, severe accidents such as gas explosion due to roadway blockage and gas accumulation and the like are avoided, and casualties are avoided or reduced.

Description

technical field [0001] The invention relates to a rock burst alarm method based on image recognition acceleration characteristics, and the method relates to the fields of image processing, communication and the like. Background technique [0002] Coal is the main energy in my country, accounting for about 70% of the primary energy. The coal industry is a high-risk industry, and accidents such as gas, flood, fire, roof, and coal dust have plagued coal mine safety production. Most of the major accidents in my country's coal mines are severe gas accidents, and the number of casualties caused by gas accidents is also the largest proportion of all coal mine accidents. Therefore, the prevention and control of gas accidents is very important. [0003] Gas accidents include gas explosion, rock burst, gas suffocation, gas burning and other accidents. In order to avoid or reduce the occurrence of rock burst accidents, a variety of coal or rock and gas outburst prevention and contro...
