Abstract
A system for controlling water distribution from a water distribution vehicle includes spray heads for spraying water from the vehicle and an actuator system for turning the spray heads on and off. A computer processor is programmed to control the actuator system in response to a sensor input. The system can include means for measuring the ground speed of the vehicle, such as a GPS, and the sensor input signal can be associated with the ground speed of the vehicle. Using a pulse width modulated signal, the processor can adjust water flow from the spray heads based on the vehicle ground speed. The processor also can be programmed to prevent water flow from one or more spray heads when the vehicle speed is below a minimum speed or as the vehicle speed is reduced.
