Abstract

The Modular Production System (MPS) can be used to reproduce nearly any function in complex manufacturing processes. In this work a different way of real time TCP/IP control of three different MPS controlled by embedded processors inside a FPGA is proposed. The digital design with FPGA is particularly advantageous due to its parallel processing made possible by its flexible structure, high integration and velocity. The TCP/IP control is carried out with a Rabbit Core microprocessor. This device contains the functions required to implement a web server allowing the remote control of the MPS. A user enters a public IP direction on a designed web page to enable/disable each independent manufacturing process.

Keywords: MPS, FPGA, Picoblaze, TCP/IP.

 

Resumen

Los MPS son Sistemas Modulares de Producción que pueden utilizarse para reproducir casi cualquier función en procesos complejos de fabricación. La propuesta de éste artículo se basa en el procesamiento en tiempo real de tres sistemas modulares de producción controlados por procesadores embebidos en un solo circuito integrado VLSI, específicamente un FPGA. El diseño digital con FPGAs presenta una gran ventaja por su procesamiento en paralelo debido a su estructura flexible, alta velocidad e integración. Otra característica importante de esta implementación es que los sistemas de producción son habilitados/deshabilitados a distancia a través de una página web, mediante la implementación de un microprocesador Rabbit que contiene las funciones de servidor de red integradas. El usuario deberá ingresar una IP pública en la página Web diseñada para habilitar/deshabilitar independientemente cada proceso de manufactura.
