ABSTRACT:
An agricultural chemical sprayer is disclosed using special pre-coded machine-readable chemical containers which, when attached for use, become an integral part of an automatic spray control system. The pre-coded data derived from a given container effectively prevents unauthorized and unsafe container refilling operations and, at the same time, automatically provides optimum control over the spray application rate (pump operation and/or electrostatic voltage), prevents mixing of incompatible spray solutions, prescribes proper spray system flushing procedures, and at all times after filling maintains an irreversible account of the available liquid remaining in the container. Provisions are made for monitoring the condition and/or operation of each spray nozzle and special connectors are provided for effecting optimum liquid and electrical circuit connections in such a system. A distributed logic microprocessor-based electronic control system, a modular nozzle design incorporating a customized I/O integrated circuit and a special container design including a customized PROM integrated circuit are provided in the preferred embodiment.
