I. Analysis of the needs of the fire protection industry

At present, most of the domestic fire safety automation systems rely on alarm detection devices such as temperature, smoke, and UV, as well as manual methods for manual alarm buttons and fire telephones. There are many cases of false alarms and artificial false reports. Inappropriate handling of false and false reports will cause unnecessary panic and loss and damage the image of the fire brigade. Therefore, the determination and confirmation of fire alarms are an important part of firefighting work. Because the efficiency of relying on telephone and manual confirmation of fire alarms is low, and many units do not have full-time fire watch personnel, automated fire and fire linkage measures that use secondary confirmation methods cannot solve this problem well, resulting in the current fire alarm determination method. Absence.

How to improve the level of modernization of fire prevention in firefighting work, early detection of fires through high-tech equipment, avoidance of dangers, and minimization of the damage caused by fires, a much needed visual aid. Based on the above actual conditions, the use of thermal imaging technology/products can effectively achieve early detection and early prevention of fire risks.

The infrared thermal imager has a very prominent application in the field of modern firefighting, which can help us to quickly determine the location of the fire source and improve the efficiency of firefighting. It can be used in forest fire prevention, electrical equipment, on-site firefighting and so on.

Infrared Thermal Imaging Smart Alert Dual Band Camera is a long-range thermal imaging camera based on the latest fifth-generation uncooled infrared technology and continuous zoom infrared optical technology. It uses a high-sensitivity 640X480 resolution uncooled focal plane imaging detector, advanced digital circuitry and image processing algorithms to provide detailed and smooth images. Specially designed optical zoom lens, taking into account the dual application needs of search and observation. Built-in intelligent analysis module, hot spot detection algorithm, can automatically detect long-distance flame, vehicles, personnel and other heat source targets, and supplemented with heavy-duty 360 degree pan/tilt, can realize fire detection and alarm display in the other circle within 6000m. . The overall enclosure adopts super-strong aluminum alloy to achieve IP66 protection grade, which can be sealed and filled with nitrogen to ensure long-term operation of equipment in the harsh loop mirror in the field. With special FR2000 fire warning platform software, video display, control, storage, playback, and automatic control scanning, automatic processing of alarm information, alarm recording, automatic calibration calibration fire spot location, false alarm management, GIS map information display Specialized functions such as access to weather data, hierarchical management, dynamic fire evolution, and tactics for fire fighting are very suitable for remote monitoring and early warning of fire prevention automation.

Second, thermal imaging camera application features

(a) Fire detection

The thermal imaging camera can display the temperature field of the object and change the temperature distribution of the target surface, which cannot be directly seen by the human eye, into a thermal image representing the temperature distribution of the target surface that can be seen by the human eye. The temperature can be detected immediately by monitoring the temperature field. Abnormality, prevention of hidden dangers caused by abnormal temperature, such as fire.

Thermal imaging cameras are the only diagnostic technology that can instantaneously visualize and verify thermal information. The thermal imaging camera quantifies the non-contact detected infrared thermal energy and can accurately measure the surface temperature of the photographed object. By analyzing the thermal energy distribution and temperature of the photographed scene, the thermal imaging camera can realize the abnormal diagnosis of the environment or the object. Tracks scenes or areas of high temperature targets, and alarms when the temperature is above a set point.

Thermal imaging technology is used to analyze the fire situation in real time, determine the distribution of fires, locate the wounded, provide accurate and effective data analysis and technical support for the fire department to rescue and rescue the on-site personnel, and obtain pre-disaster and disaster-site thermal imaging video recordings. The relevant data provides a strong basis for the fire department to investigate the cause of the fire and the inspection department to obtain evidence and accountability.

(2) Fire warning The thermal imaging camera is used to monitor the flammable area around the clock. When the temperature in the area rises sharply, an alarm is automatically triggered. Before the fire has occurred, measures are taken for the fire department to obtain the decision time.

(C) The system through infrared thermal imaging temperature warning system, can quickly detect and discover over-temperature targets, indicating the location of high-temperature point and send out an alarm, auxiliary visible light camera to confirm, and ultimately identified as fire insurance.

Infrared thermal imaging technology has become a high-tech technology that has attracted much attention. The role of infrared thermal imager in future fire safety can not be underestimated. With the acceleration of social life and modernization process, infrared thermal imaging is not suitable for fire protection and fire protection. The lack of detection methods will surely be applied more widely.
