The controller 101 may be configured to periodically acquire screen color data detected by the color sensor 102; comparing and calculating the screen color data of the current period with the screen color data of the previous period to obtain color variation; determining whether the screen color of the advertisement screen is abnormal or not according to the color variation; and in the case that the screen color of the advertising screen is determined to be abnormal, sending a screen color abnormal report message to the server.
The color sensor 102 may be an RGB (Red Green Blue ) color sensor, and the color sensor may detect light intensities of different colors of the screen, and convert the light intensities into digital output signals to obtain screen color data. When the advertisement screen normally plays the advertisement, the screen color data detected by the color sensor is changed; when the advertisement screen has a fault, such as a white screen state, a black screen state or a screen splash state, the color data of the screen detected by the color sensor is unchanged for a long time, so that the color variation can be obtained by periodically acquiring the color data of the screen and comparing the color data of the screen in two periods before and after the periodic time, and whether the color of the screen of the advertisement screen is abnormal or not can be further determined according to the color variation. The period for acquiring the screen color data detected by the color sensor may be a preset time period, and may be any value between 1 second and 60 seconds, for example, 5 seconds or 10 seconds.

And secondly, determining that the screen color of the advertisement screen is abnormal under the condition that the color variation obtained by calculation in the preset number of detection periods is less than or equal to a preset variation threshold value.
The preset number may be set empirically, and may be any number between 1 and 60, for example. Therefore, through multiple detections, the color variation is smaller than or equal to the preset variation threshold, that is, the screen color is not changed all the time within the first preset time, and it can be determined that the screen color of the advertisement screen is abnormal.

Therefore, the color data of the screen of the advertisement screen can be normally detected, and the display effect of the advertisement screen is prevented from being influenced.
Further, in the case where the above color sensor is plural, each color sensor may detect and obtain respective screen color data.
The controller may be configured to periodically acquire a plurality of screen color data detected by a plurality of color sensors; comparing and calculating the screen color data of the current period with the screen color data of the previous period to obtain a plurality of color variations of a plurality of color sensors; at this time, the manner of determining whether the screen color of the advertisement screen is abnormal according to the color variation may include any one of the following two manners:
the method comprises the steps of firstly, comprehensively calculating the color variable quantities of the plurality of color sensors to obtain a comprehensive color variable quantity, then taking the comprehensive color variable quantity as a new color variable quantity, and determining whether the screen color of the advertising screen is abnormal or not according to the new color variable quantity.
And secondly, respectively determining whether the screen color of the advertisement screen is abnormal according to the color variation of each color sensor, and if the screen color of the advertisement screen is abnormal according to the color variation of any one color sensor, determining whether the screen color of the advertisement screen is abnormal.
