when the corresponding LED lamp body is switched from a low-power lighting state of a warm color lamp to a high-power lighting state of a cold color lamp, acquiring color temperature power switching time (namely, the difference value between the switching starting time and the switching ending time of the next switching process), wherein the color temperature power switching time is too short, which indicates that the switching process is too fast to easily cause shooting exposure and influence monitoring image quality, and the color temperature power switching time is too long, which indicates that the switching reaction is relatively slow and the switching process is abnormal; invoking a preset color temperature power switching time range which is recorded and stored in advance, performing numerical comparison on the color temperature power switching time and the preset color temperature power switching time range, and generating a gradual change control abnormal signal if the color temperature power switching time is not in the preset color temperature power switching time range;
if the color temperature power switching time length is within the preset color temperature power switching time length range, setting a plurality of groups of power increase capturing time points in the time period related to the corresponding color temperature power switching time length, wherein the time intervals between two adjacent groups of power increase capturing time points are the same, marking the power increase capturing time points as i, i=1, 2, …, n, n represents the number of the power increase capturing time points and n is a positive integer greater than 1; acquiring an actual measurement value of the operating power of a corresponding LED lamp body at a corresponding power increase capturing time point i, establishing a rectangular coordinate system by taking time as an X axis and the actual measurement value of the operating power as a Y axis, drawing a standard power gradual change growth curve in the rectangular coordinate system, wherein the standard power gradual change growth curve is a power gradual change curve in the normal switching process of the LED lamp, presetting and inputting and storing the actual measurement value of the operating power of n groups by corresponding management personnel or programs, and marking the actual measurement value of the operating power of the n groups in the rectangular coordinate system according to a time sequence to generate n power analysis coordinate points in the rectangular coordinate system; connecting n power analysis coordinate points in a rectangular coordinate system one by one through line segments to form an actual power gradual change growth curve, and generating a gradual change control normal signal if the actual power gradual change growth curve is completely overlapped with a standard power gradual change growth curve;
