Problems solved by technology

[0003] 1. Washing away the roadway, burying, submerging and blocking personnel
[0004] 2. Accompanied by water inrush, there will be a large amount of coal slime and rock silting up the roadway, which will cause difficulties for personnel to escape
[0005] 3. Damaged equipment
[0006] 4. A large amount of poisonous and harmful gas gushes out, which worsens the living conditions and environment of those who have not escaped in time
At present, flood early warning is mainly based on hydrological detection and prevention, underground water detection, and aura phenomenon observation and monitoring. Hydrological detection and underground water detection can prevent underground flood accidents. Hydrological detection and underground water exploration cannot completely prevent the occurrence of water inrush, let alone give an alarm for sudden underground water inrush; the observation of aura phenomena is mainly based on human experience and judgment, and there are relatively large subjective factors
At present, on-site water inrush accidents mainly rely on the manual alarm of the on-site personnel. However, when the water inrush occurs in an unattended time or area, or the on-site personnel flee in a hurry and fail to call the police actively, the dispatching room cannot obtain timely information about the occurrence of the emergency. If the water information cannot be notified to the relevant underground staff in time, so that emergency measures cannot be taken in time for the water inrush accident, which will easily cause water damage out of control and casualties

Embodiment Construction

[0020] Such as figure 1 As shown, the system composition mainly includes:

[0021] 1. The camera (101) adopts the explosion-proof analog camera required by the coal mine explosion-proof, with auxiliary light source, and is installed in the coal mine underground excavation work face, coal mining work face or other work faces where water seepage accidents may occur, through the coaxial Cable is connected with video splitter (102).

[0022] 2. A video splitter (102), responsible for dividing one analog signal output of the camera into two outputs, one of which is connected to the image and water inflow monitoring equipment (103), and the other is connected to the video server (105).

[0023] 3. The image and water inflow monitoring equipment (103) receives an analog video signal output by the video splitter (102), is responsible for monitoring the video and drainage channel flow data, and sends a flood alarm signal to the monitoring terminal according to the monitoring results. ...

Abstract

The invention discloses an underground flood alarm system based on an image and water inflow monitoring device. Cameras are installed on driving working faces, coal faces, or other working faces of an underground coal mine to which water inrush accidents may occur, and the cameras are connected with the image and water inflow monitoring device and a video server through a video branching unit. The image and water inflow monitoring device acquires water inflow data, and monitors onsite videos and water inflow data, and sends flood alarm data to a monitoring terminal according to a monitoring result. Production management persons can check onsite real-time and historical videos through the monitoring terminal, and carry out corresponding emergency processing. The alarm system gives full consideration on characteristics of floods in a coal face of an underground coal mine, and the system is simple to apply. Corresponding measures are automatically taken in time, and the system accurately gives out an alarm on mine water inrush in first time, and buys valuable disaster relief and escape time for underground personnel who are not on the site of the water inrush in other regions.

Description

technical field [0001] The invention relates to an underground flood alarm system based on image and water inflow monitoring equipment, and the system relates to the fields of image pattern recognition, sensor, 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. Among the major accidents in coal mines in my country, mine floods are the most harmful natural disasters to mines. Calculated by the number of deaths in coal mine accidents, water accidents accounted for 15.72%, second only to gas and roof accidents, ranking third. After a flood accident, the hazards include: [0003] 1. Wash away the roadway, bury, submerge and block people. [0004] 2. Accompanied by water inrush, there will be a large amount of coal slime and rock silting up th...
