Embodiment Construction
[0037] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0038] Such as figure 1 As shown, a visual device-based short-circuit early warning device provided by an embodiment of the present invention includes: a visual device 1 , a cache queue 2 , a video memory 3 , an embedded processor 4 and a photosensitive sensor 5 . Among them, the visual device 1 is used to collect the real-time video of the power equipment; the buffer queue 2 is used to cache the real-time video collected by the visual device 1; the photosensitive sensor 3 is used to detect the ambient light, wherein, when the detected When the brightness of the ambient light exceeds the preset value, a trigger signal is sent to the embedded processor; otherwise, the trigger signal is not sent to the embedded processor; the embedded processor 4 is used t...

The invention provides a short-circuit warning device based on a visual device, comprising: a visual device for collecting real-time video of electric equipment; a cache queue for buffering the real-time video collected by the visual device; a photosensitive sensor, It is used to detect ambient light, wherein when the brightness of the detected ambient light exceeds the preset pre-value, a trigger signal is sent to the embedded processor, otherwise, the trigger signal will not be sent to the embedded processor; the embedded processor, using According to the trigger signal, the video collected by the visual device is stored in the video memory, and the video in the video memory is processed to determine whether the video in the video memory is short-circuited. The invention can obtain the damage process of the accident scene intuitively and with low resource occupation, and analyze the direct cause for the short-circuit fire.
Description
technical field [0001] The invention relates to a short-circuit early warning device, in particular to a short-circuit early warning device based on a visual device. Background technique [0002] Short circuits in the power system are prone to discharge, which can cause relatively large damage to electrical equipment. Therefore, short circuit detection and early warning are very important. The technical route is to adopt the circuit direction, which is to install a short-circuit trigger device in the equipment that may be short-circuited. Once the circuit is short-circuited, the trigger device will send out an early warning signal. However, in this technical route, only early warning can be performed, but the situation after early warning cannot be known, such as the destruction process of fire caused by short circuit after early warning. Therefore, how to obtain the damage process of the accident site intuitively and with low resource consumption, and analyze the direct c...
