Abstract
An electro/hydraulic system for controlling remotely located valves or other types of hydraulically powered equipment. The electrical system uses multiple microprocessors to send, validate, and execute commands. Microprocessors at the central control station constantly communicate with and monitor similar microprocessors at remote locations. The validation of commands increases safety and reliability of the present invention as compared to direct electrical control systems. The electrical components of the present invention greatly decrease the lapse time between initiating a command at the central location and equipment response at the remote location. The system also monitors and displays temperature, pressure, and valve position.
