χ226590 V. Description of the invention (1) Technical field to which the invention belongs The present invention relates to the prior art: As the subject gradually improves. The clean room of I is expensive. Therefore, it is expected that the existing detection is set, that is, the protection system or the fire alarm and extinguishing system. ^ The conventional technology system, such as the t-detection system, image monitoring, identification, image photography, etc. Advance early. However, most of the systems are still usually used. Advances in technology are, in some specific terms, only important to be able to respond immediately in advance. Fire protection system Actions such as fire detection in fire prevention facilities. During the operation, the methods of the Republic of China and the method of public notice have been adopted to prevent special effects. The conventional image recognition has its inconveniences, such as general house or electrical component temperature rise recognition classification method. Human requirements for various disaster protection are also called locations, such as precision laboratories or semiconductor factory equipment or workpiece materials are often costly to detect a fire, and the primary purpose of the fire must be the first purpose. Therefore, the fire protection system and the fire control system or fire protection facilities generate smoke and the position of the high-level detector, so that they can respond to the above-mentioned passive infrared thermal image straightening announcement No. 4 6 6 1 0 7 47622 1 Active infrared thermal imaging in a fixed area to adjust the temperature rise.

Parts, etc., which are most prone to fire during production. The most common factors are presumably due to the generation of smoke in the electrical laboratory, that is, the circuit components are close to burning and disaster. However, when the smoke begins to generate combustion conditions, the fire is easy to react to; 'But the condition of the equipment or its workpiece materials or damage, etc., affects and harms. At this time, if the above-mentioned conventional monitoring system is used to perform the standard value of the detection of the closed space, so that the setting of the instrument has not reached the standard value, that is, in a laboratory or a semiconductor factory, under high or low temperature conditions, the same, And each has a different operating safety temperature, which must be far south than some specific components used in general electrical processes, and even produce combustion reactions. The system performs detection, not only the temperature detection detection or monitoring system generates a warning, but also is prone to errors. It is usually caused by a fire & when its power system or power does not consider special occasions. For example, one may indicate the fire point of the electrical system of the equipment. Although no fire occurs at this time, it means that the temperature has reached the ignition point. The disaster may be fired in the first reaction time at any time within a very short time. The material may still be deteriorated due to high temperature, which may be enough to cause irreparable disasters. Infrared thermal image integrated detection or temperature detection, although the temperature of the power system or circuit components can be set to warn first. However, some experiments or processes may be precise in the specific use of electronic components with different ignition temperatures; for example, the temperature of a heater element or device, while the low temperature system may be around normal temperature. When the standard value of infrared detection or monitoring is not easy to determine, and it is difficult to distinguish the temperature abnormality during operation, the cause of high temperature cannot be identified correctly.
