System and method for controlling the release of material

摘要

A system includes one or more actuators (such as valve assemblies) that are configured to release a material. The system also includes a wireless receiver configured to receive wireless positioning signals. The system further includes a processing device configured to determine a position associated with the one or more actuators based on the wireless positioning signals and to determine whether to open or close the one or more actuators based on the determined position. In addition, the system includes a controller configured to control the opening and closing of the one or more actuators based on signals from the processing device. The processing device may be configured to determine whether to open or close the one or more actuators by determining whether the material has already been released at the determined position.
