The fire detection in substation is required to be fast and exact

due to its special surroundings

smoke detection is a commonly used method in early fire detection

therefore

a fast smoke detection algorithm is proposed for such unique environment. The specific steps are as follows: Firstly

moving area are determined in real-time by using the improved Vi Be algorithm. Then

the suspected smoke area will be identified by judging color features of the detected regions. Finally

the smoke diffuse and moving characteristics are considered to ascertain the real smoke region. Experimental result shows that this algorithm can be used to detect smoke in different situations

it is not only suitable for nearby smoke detection

but also quite useful for detecting thin smoke in distance. Therefore

this algorithm

which meets the requirements of real-time and accuracy of fire detection in the substation

can be applied in smoke detection in the substation.
