Spraying control method for prefabricated bridge based on environmental information collection

The invention relates to the technical field of prefabricated bridge maintenance, and particularly discloses a spraying control method for a prefabricated bridge based on environmental information acquisition, which comprises the following steps: after spraying and replenishing water to the prefabricated bridge through a spraying device in an initial direction, obtaining the surface humidity of the prefabricated bridge again, and obtaining the humidity change amplitude according to the data obtained twice; the spraying direction of the spraying device is readjusted through the controller according to the humidity change amplitude, and a recommended spraying direction set of the current environment wind is obtained, the spraying direction can be continuously adjusted according to relevant parameters of the environment wind in the long-time and all-weather prefabricated bridge maintenance process, and the maintenance efficiency of the prefabricated bridge is improved. Therefore, the optimal humidifying effect u
