SYSTEM AND METHOD FOR LAND APPLICATION OF WASTE FLUIDS

摘要

A system and method are provided for automated control of application of fluid to a surface. A surface map is annotated with shapes designating zones for spraying, and excluding others. A control system in a vehicle uses the annotated map and GPS to assist the operator of the vehicle avoid spraying on excluded zones, and provides a record of the spraying operation including locations sprayed and fluid spray rates. The control system operates valves to control spraying from a container on the vehicle, based on several parameters, so as to avoid spraying excluded zones and steep slopes, to avoid overlaps, and to limit fluid spray rates below pre-determined maximums. The system further assists the operator by providing a visual guide on a display. A kit can be provided to retrofit a vehicle for landspraying.
