A readout circuit of infrared focal plane array (FPA) and a control method therefor. The readout circuit is connected to an infrared FPA, which comprises a plurality of pixels. The readout circuit comprises an integral and readout unit, a correction unit and a digital control unit. For each pixel, the correction unit determines an initial bias value based on a to-be-corrected parameter value for the pixel; the integral and readout unit determines, based on a first current corresponding to the initial bias value and a second current caused a pixel response temperature value, a responsive voltage value for the pixel; and the digital control unit adjusts, based on a comparison result between the responsive voltage value and a preset voltage value, the to-be-corrected parameter value for the pixel, to obtain an adjusted parameter value, and determines, based on the adjusted parameter value, an optimal corrected parameter value for the pixel.

Disclosed is a multi-dimensional analysis method for a tripping risk of a whole transmission line due to a lightning shielding failure. A quantity of thunderstorm days, a tower size, a terrain proportion, an altitude, and insulation configuration data are collected for a transmission line for which a tripping risk due to a lightning shielding failure needs to be analyzed, and a striking distance, an exposure distance, a lightning resisting level of the line after altitude factor correction, and a lightning shielding failure risk of a single-base tower are calculated in turn. Characteristics of a lightning shielding failure under different nominal heights, quantities of thunderstorm days, and terrains are studied. Representative combination conditions are selected to calculate a tripping risk of a typical tower due to the lightning shielding failure. A weight coefficient is extracted, to calculate a tripping risk of the whole line due to the lightning shielding failure.

The embodiments of the present application provides a method and apparatus for preventing heat damage to a thermal imaging camera. The method includes: obtaining a thermal imaging picture of the thermal imaging camera; detecting whether the thermal imaging picture shows that a high-temperature object appears in the picture of the thermal imaging camera; confirming that the thermal imaging picture shows that a high-temperature object appears in the picture, generating a heat damage alarm signal, and closing a baffle if the baffle is not closed currently. In the present application embodiments, after detecting a heat damage alarm signal, that is, after detecting that a high-energy radiating object enters an image picture, the baffle is closed immediately, thereby avoiding the risk of the sensor being permanently burnt due to directly face to the high-energy radiating object.
