The control project, automation and supervision for SMEs, it's based on a system of open architecture, using principles of systems SCADA with the development of intelligent routines taking advantage of the advantages of the technology of the microcontrollers and DCE, for the control of physical variables, processes and digital treatment of data; coming from the different implemented RS, such as: point of pumping in underground well, filled of recipients, flow, electrovalves, as well as the gradual distribution and temporized in cultivation sectors using valves adapted mecatronicamente, all them with programming algorithms developing the process in real time. The system sense the different physical variables, it controls actuators, it establishes alarms and states of emergency stop through the RS, it processes them to their equivalent one digital it stops then to create the plots of information of this variable and later on to be correspondents to the BS, for their visualization in the control power station by means of the digital transmission of data governed by a communication protocol. All these characteristics are translated in optimization of watering control and in efficiency of manipulation of present variables in the system favoring with technical and technological attendance to the SMEs. © 2009 IEEE.
