Fire detection industry solution

Summary

Dangerous places, ammunition depots, oil depots, chemical factories and other inflammable and explosive places to prevent malicious intrusion, protect personal life and public property to prevent malicious invasion, ensure the safety of personal life and public property, provide real-time and online monitoring and warning, prevent escape from prison and illegal invasion, and ensure that the public safety is guaranteed to provide real time. On-line monitoring and warning to prevent escaping from escaping and unlawfully invading, providing all weather real-time intrusion events positioning alarm and intelligent discrimination to provide efficient security for the safe operation of the airport area.

Fire alarm detection system

In metallurgy, coal and other industries, fire, electricity consumption and gas consumption are large, and there are inflammable and explosive fire hazards, and great fire accidents are extremely easy to occur. There are many layers of high-rise buildings, scattered functions and densely populated, and fire rescue work is arduous and difficult, and it is a great threat to people's life and property safety. The sky feed line in radio and television transmission system has the maximum transmission frequency for the year, and the installation environment is generally in the outdoor and high altitude, relatively bad, the construction and maintenance is larger, so once the failure will probably cause a number of channels to stop.

A series of temperature monitoring systems have been developed to ensure the safe and stable operation of the industry, based on the characteristics of optical fiber intrinsic safety, explosion proof, accurate temperature measurement and suitable for complex environment.

Industry background

Grain depot is a place where the state and collective store grain, which is related to the national grain reserves and the high level of fire prevention. However, because of the spontaneous combustion of grain, insecticide and Rodenticide, flammability, electrical wiring aging and short circuit, there are fire risks in grain depots. The sensor needs to bury the sensor into grain. The distributed fiber fire detector uses optical fiber cable as the sensor. There is no power supply without electrical fire risk, and the cable can be retractable. It is suitable for the temperature of grain warehouse and fire detection.

Tobacco warehouse has fire risk because of its own heating and even spontaneous combustion, common fumigating insecticides and inflammable substances and electrical lines aging and short circuit. In the detection of tobacco spontaneous combustion, the sensor needs to be embedded into the tobacco. The distributed fiber fire detector uses optical fiber cable as the sensor. It does not need power supply without electrical fire risk, and is suitable for the application of fire detection in tobacco warehouse.

Underground garage has fire risk due to vehicle self ignition and electrical line aging and short circuit. The underground garage belongs to the closed space, the burning speed is fast, the ventilation and exhaust smoke and the fire fighting and rescue are difficult. The fuel gasoline used in the parking vehicle belongs to flammable goods, so it has brought many difficulties to the fire fighting work. The distributed optical fiber fire detector uses optical cable as sensor, which can accurately detect the temperature and fire situation of each parking space and guide the precise fire fighting.

Forest fire prevention, people are responsible. However, due to weather drought, spontaneous combustion, human factors, self ignition factors and other reasons, forest fires are inevitable. How to effectively predict the fire and identify the flame position and spread trend after the fire will contribute to the development of forest fire prevention. The distributed optical fiber fire detector uses optical fiber cable as sensor and does not need power supply on site. The system uses the underground optical cable to identify the fire alarm in the area of the fire area. At the same time, it analyzes the temperature difference of the optical cable in each region to identify the fire spread trend, and provides the decision support for the forest fire extinguishing.
