Problems solved by technology

At present, the monitoring methods for external fires in mines mainly use temperature monitoring and smoke monitoring, etc. Smoke monitoring has the disadvantages of slow response, high false alarm rate and false negative rate; currently more advanced method of temperature monitoring is to use optical fiber distribution temperature monitoring, but optical fiber is prone to Damage, complicated installation, difficult maintenance, etc.

Embodiment Construction

[0024]figure 1 It is a schematic diagram of the composition of a fire monitoring and alarm system for outside mines. The composition of the system includes:

[0025]1. Information processing server (1): Responsible for storing the data of each sensor, and monitoring the data changes of gas concentration data, temperature data and flame monitoring data, and sending out fire alarm signals by analyzing the data changes.

[0026]2. Alarm device (2): The information processing server controls the sound and light alarm, and communicates with the information processing server through the RS232 interface.

[0027]3. Monitoring equipment (3): Provide data query and production monitoring services for production management personnel. The information processing server provides on-site data with alarm display and GIS service functions.

[0028]4. Core switch (4): Responsible for the management and data exchange of all equipment connected to the mine Ethernet, and is connected to the underground switch (5) t...

Abstract

The invention discloses a mine external fire monitoring and alarm system. Exogenous fires in mines have the characteristics of difficulty in detection and rapid development. The traditional external fire alarm system takes a long time to respond and is prone to misreporting and omissions, making the fire unable to be controlled in time and causing a large number of casualties. The system mainly includes an information processing server, an alarm device, a communication network, a gas concentration remote sensing device, a flame monitoring device, etc.; Comprehensive analysis of monitoring data to issue a fire alarm. The system can accurately monitor the characteristic gases of external fires, greatly improves the accuracy of the alarm, and provides an important guarantee for the safe production of coal mines.

Description

Technical field[0001]The invention relates to a mine external cause fire monitoring and alarm system, which relates to the fields of sensor technology, laser technology, spectrum analysis technology, signal processing technology and the like.Background technique[0002]Coal is my country's main energy source, accounting for about 70% of primary energy. The coal industry is a high-risk industry, and accidents such as gas, fire, roof, coal dust, etc. plague coal mine safety production. Coal mine fires include internal fires and external fires, and external fires have the characteristics of difficult discovery, rapid development, difficulty in extinguishing fire and rescue. Once a fire occurs, if the fire cannot be controlled in time, the scope of the fire will rapidly expand and cause a large number of casualties. Therefore, timely detection of fire outside the mine is of great significance. At present, the monitoring methods for fire outside the mine mainly use temperature monitoring a...
