Diseño e implementación de un módulo de monitoreo y control de nivel de agua basado en un computador, a través del PLC utilizando LabVIEW para el Laboratorio de Control.

Abstract

It was design and I build a didactic module of monitoreo and control of the level of the water to be installed in the laboratory of Control of the EIE-CRI. The process is carried out in two tanks, a main one and a secondary one the water it will be taken of each other through pipe installed for the effect. The team allows to control the level of water through two actuadores, a bomb that gives water from the secondary tank to the main tank whose flow will be manipulated by a servovalvula, forming this way a closed circuit of water. The servovalvula was built starting from a sphere valve coupled AD to a motor that it is the actuador of the valve. The opening of the valve is measured through the voltage sign given by a sensor QRD. The taken sign of the sensor is conditioned AD by a pic that he/she sends signs to a bridge Hfor the control of the motor The control of the variable level of water is made by means of a PLC, the same one that is the one in charge of to process the data and to take the respective actions for the control of the variable Level. The monitoreo one can make from two locations: to) Local Control that is in the operator panel and b) automatic Control is carried out through a PC The control is carried out it in a manual way as automatic. once built the system of control and monitoreo of level of water the students of the EIE CRI could carry out practical of laboratory in mensuration, control and monitoreo of the variables of the level of the Iliquidate For what is recommended to integrate the I modulate didactic of monitoreo and control of the level of the water in the instrumentation matter and sensors.
