Embodiment Construction

[0048] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0049] Take the infrared monitoring of coal gasification plant as an example. figure 1 , 2 It is a simplified workflow diagram and architecture diagram of the monitoring system. First of all, use a handheld thermal imaging camera (that is, a portable thermal imaging camera, manually carried, and collect infrared image information) or a fixed infrared thermal imaging camera (fixed installation , monitor a certain area of ​​the device in real time, collect infrared video stream information) collect infrared pictures and video data, and complete figure 2 The process of middle red circle 1. Among them, when using a hand-held infrared thermal imager, use the "base map recognition" function to artificially set an infrared thermal image in the normal state of the monitoring device as a "standard image", and take the infrared standard image of the g...

Abstract

The invention discloses an infrared standardized intelligent early warning / alarm wireless transmission system for a refinery device, and belongs to the technical field of infrared monitoring. The system comprises a terminal acquisition unit, a cloud database storage unit, a data deep analysis unit, a webpage cloud display unit and an abnormity alarm feedback unit. The system is used for monitoring the temperature field of the outer surface of equipment in a refinery enterprise, and machine self-learning analysis can be carried out on the temperature change trend of the outer surface of the device according to the specific temperature change characteristics of the refinery device, so that temperature threshold alarm and trend early warning are carried out on an abnormal area, and data are uploaded and downloaded through a wireless network; the system is simple to operate and high in monitoring accuracy, and can predict abnormal problems such as coking, corrosion and damage in the device through trend analysis of the temperature of the outer surface of the device so as to realize predictive maintenance.

Description

technical field [0001] The invention belongs to the technical field of infrared monitoring, and in particular relates to an infrared standardized intelligent early warning / alarm wireless transmission system for refining and chemical equipment. Background technique [0002] The infrared intelligent analysis system of refining and chemical equipment is used to monitor the temperature field on the outer surface of the equipment of refining and chemical enterprises. Since refining and chemical equipment is different from electric power or railway equipment, the structure of equipment pipelines is complex, and different areas have different degrees of sensitivity to temperature. Manual monitoring or Analysis is quite difficult. And because the temperature of refining and chemical equipment changes slowly, it is difficult to find faults through manual timing monitoring, and the infrared images collected manually in the past are only used to check the temperature status at that tim...
