However, because the information prompt board is set in the open air and has a certain height, it is easily polluted by the outdoor environment. If the front of the information prompt board cannot be kept clean, the pollutants will cover the entire surface, seriously affecting the driver's visual inspection and not conducive to traffic. In general, the cleaning of the information warning signs is generally done by the maintenance personnel setting up a ladder to climb up and wipe. The operation process is cumbersome and laborious, and the cleaning is difficult. Larger, there is a greater security risk
