Embodiment approach 1

[0033] Such as figure 2 The system shown mainly includes:

[0034] 1. Video recognition server (201). 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.

[0035] 2. Monitoring host (202); with sound and light alarm function, production managers can view live video images, sensor data changes and equipment failures through the monitoring host, and can manually issue 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.

[0036] 3. Storage server (203); responsible for collecting and storing camera signals, various sensor signals and equipment failure signals, and providing query and retrieval services ...

Embodiment approach 2

[0049] Such as Figure 4 The system shown mainly includes:

[0050] 1. Storage server (401); responsible for collecting and storing video signals, alarm signals, methane sensor signals and equipment working conditions, and providing query and retrieval services for users.

[0051] 2. Monitoring host (402); with sound and light alarm function, production management personnel can view live video images, alarm conditions, methane sensor data and equipment conditions through the monitoring host, and can manually send out alarms 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.

[0052] 3. Monitoring the standby machine (403); when the monitoring host breaks down, the monitoring standby machine works.

[0053] 4. Network switch (404); responsible for the management and dat...

Abstract

The invention discloses a coal face coal and gas outburst alarm method based on images. The alarm method includes the steps that cameras are installed nearby coal face related areas, video image data changes and device working conditions are analyzed in real time, abnormal data changes in the monitoring areas are found, and a coal and gas outburst alarm and power-off locking signal is sent out if the information-abnormal combination conditions meet an alarm condition. The coal face coal and gas outburst alarm method sufficiently considers various characteristics of a coal-mine coal face coal and gas outburst, implementation is simple, the coal face coal and gas outburst can be accurately determined, accidents such as gas explosions caused by contact between coal and gas can be effectively avoided, and life losses and personal injuries caused by gas suffocate and the gas explosions are avoided or reduced.

Description

technical field [0001] The invention relates to an image-based coal and gas outburst alarm method in a coal mining face, 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, coal and gas outburst, gas suffocation, gas burning and other accidents. In order to avoid or reduce coal and gas outburst accidents, people have proposed a variety of coal or rock and gas outburst preven...
