Live detection system, method, and thermal infrared imager for power grid equipment

A live detection method for power grid equipment, comprising following steps:

• S1, acquiring environmental temperature, humidity and wind speed, and performing environmental parameter setting;
• S2, determining whether an environment meets a standard environmental requirement, proceeding to step S3, if yes, and ending detection if not;
• S3, measuring a linear distance d to the equipment, and completing detection requirement setting;
• S4, determining whether there is a need to determine whether a detection distance meets a detection requirement;
• determining whether the detection distance meets the detection requirement if yes, and proceeding to step S5, if the detection requirement is met;
• S5, intelligently recognizing an equipment type, and allowing manual adjustment if the recognized equipment type is inaccurate;
• S6, determining a material type of the power grid equipment according to the equipment type and an appearance characteristic of the equipment, and allowing manual adjustment if the recognized material type is inaccurate;
• S7, setting an emissivity according to the material type of the power grid equipment;
• S8, selecting a corresponding diagnostic model according to the type of the detected equipment;
• and
• S9, automatically focusing on positions of the detected equipment which need temperature measurement, reading temperature measurement results, performing calculation according to a corresponding determination criterion to draw a conclusion, and generating a report.
