SYNCHRONIZED APPLICATION OF ONE OR MORE MATERIALS TO A SURFACE FROM A VEHICLE

摘要

An apparatus and system (42/200) is disclosed, preferably mounted on a servi ce vehicle (40), for synchronized application of fluid materials, either solid (44) or liquid (57), to a vehicle travel surface in proportional amounts or spatially distributed proportions in response to user defined requirements and/or operation of a vehicle mounted component (70/91/114/216) in response to conditions encountered in real time. A first embodiment is a vehicle mounted apparatus and system (42) for coordinated application of a plurality of materials (44, 57) to a surface simultaneously and in desired proportions and/or widths automatically and/or selectively. A second embodiment includes a granular material distribution device (46) and includes a plurality of liquid spray headers (58/60/62) and pumping means (136/138/140). A third embodiment (200) includes an automated component control such as bla de blocking plate (242) control based on sensed current surface condition information and current accurate location information as well as past operating history and predicted near term weather conditions.
