PROBLEMA DE LA INVESTIGACION.

E
l problema que nos llevo a realizar este proyecto fue la falta de tecnología de punta en un sector muy importante en la actualidad; la salud, específicamente a los largos procedimientos al momento de esterilización de utensilios hospitalarios entre otros.

DETALLES DE LA SITUACION ACTUAL

El tema surge de la preocupación en la actualidad al observar que en nuestro hospitales no se está realizando de forma correcta el proceso de esterilización de los utensilios hospitalarios ya que en muchos casos la desinfección de dichos utensilios se realiza con iodo o alcohol, lo que puede ocasionar una propagación más rápida de virus y bacterias. Estos ...view middle of the document...

Consideramos de gran importancia este proyecto propuesto ya que nuestro país carece de un buen rendimiento en el área de la salud.
Al mismo tiempo reducir o facilitar el tiempo empleado para esterilizar utensilios hospitalarios, que sería de gran ayuda para el personal, ganando más tiempo para otras actividades.
Al montar este proyecto pretendemos solucionar el problema ya mencionado.

CONTROLADOR LOGICO PROGRAMABLE (PLC)

Es un dispositivo electrónico digital que usa memorias programables para el almacenamiento interno de las instrucciones que cumplen funciones específicas tales como lógicas, temporizadas, secuenciales conteos y operaciones matemáticas con los cuales realiza la tarea de control utilizando señales digitales o analógicas. La memoria es donde va el programa.
El CPU se encarga de ejecutar en forma ordenada el programa.
El programa LADDER o escalera se puede realizar a través de computadoras personales o a partir de un terminal de mando o de un software apropiado para PC, el lenguaje es sencillo y práctico para todos.

CAMPOS DE APLICACIÓN.

El PLC por sus especiales características de diseño tiene un campo de aplicación muy extenso. La constante evolución del hardware y software amplia constantemente este campo para poder satisfacer las necesidades que se detectan en el espectro de sus posibilidades reales.
Su utilización se da fundamentalmente en aquellas instalaciones en donde es necesario un proceso de maniobra, control, señalización, etc., por tanto, su aplicación abarca desde procesos de fabricaciones industriales de cualquier tipo a transformaciones industriales, control de instalaciones, etc.
Sus reducidas dimensiones, la extremada facilidad de su montaje, la posibilidad de almacenar los programas para su posterior y rápida utilización, la modificación o alteración de los mismos, etc., hace que su eficacia se aprecie fundamentalmente en procesos en que se producen necesidades tales como:
* Espacio reducido.
* Procesos de producción periódicamente cambiantes.
* Procesos secuenciales.
* Maquinaria de procesos variables.
* Instalaciones de procesos complejos y amplios.
* Chequeo de programación centralizada de la partes del proceso.

EJEMPLOS DE APLICACIONES GENERALES:

* Maniobra de maquinas
* Maquinaria industrial de plástico
* Maquinas transfer
* Maquinaria de embalaje
* Instalaciones de seguridad
* Señalización y control

Nuevas tendencias.

En general, los PLC son cada vez más rápidos y más pequeños y como resultado de esto, están ganando capacidades que solían ser dominio exclusivo de la computadora personal (PC) y de las estaciones de trabajo. Esto se traduce en manejo datos críticos de manera...
