Digital spray control system

A system for controlling water distribution from an industrial water distribution vehicle, the system comprising:

• a water tank of an industrial water distribution vehicle, wherein the water tank is configured to store a quantity of water and the industrial water distribution vehicle includes a hydraulic control circuit configured to drive a water pump via a hydraulic motor;
• wherein the hydraulic control circuit includes a hydraulic control manifold and one or more hydraulic control lines configured to deliver a flow of hydraulic fluid to a plurality of hydraulically controlled spray heads, each being configured to spray a flow of water from the quantity of water stored by the water tank;
• an actuator for turning each of the plurality of the spray heads on and off, wherein the actuator is configured to actuate one or more valves of the hydraulic control manifold that control the flow of hydraulic fluid to the plurality of spray heads;
• and
• a computer network comprising a processor programmed for controlling the flow of water from the plurality of spray heads in response to at least one sensor input signal;
• wherein the processor is programmed to control the flow of water from the plurality of the spray heads using pulse width modulation.
