Abstract

The invention provides a spark detecting method utilizing infrared rays and a spark detecting device utilizing infrared rays. The method is applied to a spark detecting system with a preset infrared heat source database. The method comprises the following steps: receiving a to-be-detected radiation curve measured by an infrared sensor in a preset area; comparing the to-be-detected radiation curve with a current corrected radiation base line, generating radiation increment at the detection wavelength; judging whether the radiation increment at the detection wavelength is greater than a preset threshold value at the detection wavelength or not; and if the radiation increment is greater than the preset threshold value, sending a start signal to an alarm mechanism and a fire-fighting performing mechanism. According to the spark detecting method and system utilizing the infrared rays provided by the invention, for spark detecting, reaction speed is relatively high when the spark detecting precision can be guaranteed, failure in report is avoided, the capacity of resisting disturbance is strong, and the risk treatment strategies are various, so that the spark detecting method and system can be suitable for multi-field industrial production, also can be adaptive to a complex working environment, and therefore, the range of application is effectively expanded.

Description

Technical field [0001] The present invention relates to the technical field of electronic detection, in particular to a spark detection method and system using infrared rays. Background technique [0002] With the development of the petrochemical industry, the types and applications of flammable, explosive and toxic gases have increased. Once these gases leak during production, transportation, and use, they will cause poisoning, fire and even explosion accidents. Seriously endanger people's lives and property safety. Therefore, for the production, storage, and transportation safety of petroleum, chemical, and high-dust industries, how to effectively prevent the occurrence of vicious accidents such as burning and explosion has become the top priority in the safety production process of petrochemicals. [0003] In the prior art, the spark detector is used to detect the occurrence and development of sparks, to prevent and control the combustion and explosion caused by the sparks, and...

Problems solved by technology

However, using ultraviolet spectrum technology to detect the occurrence of sparks, although the reaction time is faster, but the increment of ultraviolet radiation is small and the occurrence time is short, the sensitivity and detection accuracy of the ultraviolet sensor are high, and dangerous alarms are prone to false alarms, resulting in immeasurable loss

In addition, ultraviolet sensing technology is also extremely susceptible to interference from other factors such as light, heat and dust, thus affecting the final detection accuracy

[0005] Therefore, when the prior art is aimed at spark detection, it is impossible to have a faster response speed while ensuring the accuracy of spark detection
