The invention discloses an 
urban road watering and dust removal 
system. The 
urban road watering and dust removal 
system comprises a power supply 
system for providing 
electric energy for a dust removalsystem, a dust 
detector for detecting the 
road dust concentration information in real time, a 
central processing unit used for receiving and converting the dust concentration information into controlsignals, a watering system used for cleaning the 
urban road under control of the control signals, a 
water supply system for supplying water to the watering system under control of the control signals, and an alarm system for sending alarm signals under control of the control signals. The dust 
detector is used for detecting the urban 
road dust concentration, the 
central processing unit is used forcontrolling the watering system to clean the urban road, accordingly, the urban 
road dust content is reduced, and no influences are generated to the urban 
road traffic. The watering 
investment cost is reduced, and the situation that due to too many watering carts, the urban carbon emission is increased, and the environment is polluted is avoided; and through the alarm system, pedestrians can be reminded in time, and the situation that the watering system sprinkles water to the bodies of the pedestrians accidentally is avoided.
