Proyecto de Graduación (Licenciatura en Ingeniería en Mantenimiento Industrial) Instituto Tecnológico de Costa Rica, Escuela de Ingeniería en Mantenimiento Industrial, 2016.
The Project was made in TRIMPOT ELECTRONICAS Ltda. This is an
electronical components manufacturing enterprise. The East plant has a water
supply system conformed by a deep well pump which feeds two capture tanks
automatically and feeds manually an emergency tank.
The level control systems of the tanks was installed more than 25 years ago
and it has undergone many modifications due to component failures. Furthermore,
it did not have any monitoring system interface, which allowed observing and
controlling the actuators, besides identifying failures generating alarm messages on
the computer screen.
In this project, the control system for filling the process tanks was updated
and improved, and the emergency tank was included in the control system. This was
done with an Omron PLC controlled by ultrasonic sensors, flow sensors and
pressure transmitters. The sequence also considers the time to decrease the
probability that the well pump will start in the peak period of CNFL billing and
increase in the night period
An application was also designed in LabVIEW that communicates with the
PLC via FINS / UDP, Omron protocol, with which it is possible to monitor the status
of tank levels and volumes, pressures and specific pipeline flows, remotely control
the solenoid valves and the deep well pump, perform configurations and also
displays system alerts.
Finally, a database was implemented in Microsoft Access, which carries a
record of some variables of the system, which communicates with the LabVIEW
application through an ODBC.
