The intelligent double-side cleaning device based on the steel plate conveying production line according to claim 3, wherein the cleaning control unit generates a low-power cleaning signal for a stain-free area, a normal cleaning signal for a low-density stain area, and a strong cleaning signal for a high-density stain area, wherein the operating powers of the upper inlet brush (11), the lower inlet brush (17), the upper axial rolling brush (12), and the lower axial rolling brush (18) are higher than each other, and the operating power in a strong cleaning signal state is higher than the operating power in a normal cleaning signal state and is higher than the power in a low-power cleaning signal state.

7. The intelligent double-side cleaning device based on the steel plate conveying production line according to claim 3, wherein the cleaning control unit sends an area, in which the high-density stain area is located, to the server, the high-frequency analysis unit counts the number of times of high-density stains appearing in each area after acquiring the high-density stain area from the server, in one production cycle, if the number of times of high-density stains appearing in a certain area is larger than or equal to a preset number threshold value, the area is marked as a fault area, an equipment pollution signal is generated, the equipment pollution signal and the fault area are sent to the server, the server is sent to an external display screen through a network, and an equipment pollution text and an image containing the fault area are displayed on the display screen.

8. The intelligent double-side cleaning device based on the steel plate conveying production line according to claim 3, wherein after the administrator checks and maintains equipment pollution, a pollution elimination signal is manually input to the feedback rechecking unit, the feedback rechecking unit receives the pollution elimination signal, calls a high-density stain area from the server after the time point of generation of the pollution elimination signal, counts areas of the high-density stain area appearing in the image, does not respond if the areas of the high-density stain area appearing are different from fault areas generated when the equipment pollution signal is generated, generates a fault signal if the areas of the high-density stain area appearing are the same as the fault areas generated when the equipment pollution signal is generated, sends the fault signal to the server, and displays a text that 'pollution fault is not eliminated' on an external display screen after the server receives the fault signal.

9. The use method of the intelligent double-sided cleaning device based on the steel plate conveying production line, as claimed in claim 1, is characterized by comprising the following steps:

the method comprises the following steps: the method comprises the following steps that a steel plate to be cleaned is conveyed to the position above a supporting roller (4) in a conveying channel (1), the supporting roller (4) drives the steel plate to move forward under the action of a driving roller (3), when the steel plate passes through a sensor, the sensor acquires the stain condition on the steel plate, analyzes and processes the stain condition, and controls an upper inlet brush (11), a lower inlet brush (17), an upper axial rolling brush (12) and a lower axial rolling brush (18) which are used for cleaning;

step two: when the steel plate reaches the positions of the upper inlet brush (11) and the lower inlet brush (17), the upper inlet brush (11) and the lower inlet brush (17) perform primary brushing on the surface of the steel plate, so that stains firmly attached to the surface of the steel plate are brushed, and when the steel plate reaches the positions of the upper axial rolling brush (12) or the lower axial rolling brush (18), the spiral bristles on the upper axial rolling brush (12) or the lower axial rolling brush (18) brush the stains attached to the surface of the steel plate to two sides through rotation, so that the surface of the steel plate is cleaned;

step three: when a large number of steel plates are seriously stained at the same position in a certain period, the high-frequency analysis processing unit generates signals for the server and displays the signals through a display screen externally connected with the server, so that a worker is reminded to check and maintain the equipment.
