Abstract

The present invention relates to the technical field of thermal imaging detectors, and provides a thermal imaging camera overload protection method, device and storage medium. The method is applied to a thermal imaging camera detector and includes the following steps: Working temperature range, each working temperature range corresponds to a current safe electrical signal threshold; detect the current working temperature of the detector, and match the current safe electrical signal threshold of the corresponding working temperature range; when the thermal radiation of the temperature of the current target When the electrical signal is higher than the current safety electrical signal threshold, the thermal sensor of the protective detector is blocked. In this way, the detector of the thermal imaging camera is reasonably protected to avoid damage to its heat-sensitive element, thereby prolonging the service life and improving user experience.

Description

technical field [0001] The invention relates to the technical field of thermal imaging detectors, and in particular provides a thermal imaging camera overload protection method, device and storage medium. Background technique [0002] At present, most of the thermal imaging cameras commonly used in the market use uncooled detection methods. Among them, the detector is the key component of the thermal imaging camera. It is converted into an electrical signal, and finally an infrared thermal imaging image is formed. [0003] However, due to the limited temperature that the heat-sensitive pixels can withstand, when the radiation of an ultra-high heat source is detected, it is very easy to cause the heat-sensitive pixels to be overloaded and burned. [0004] Most of the existing thermal imaging cameras do not have overload protection, that is, when an ultra-high temperature radiation source is detected, it is easy to cause damage to the thermal imaging camera, the service life ...
