Implementation of Online Fuzzy Controller for Crude Oil Separator Industry Based on Internet of Things using LabVIEW and PIC Microcontroller

Precise control of industrial processes is challenging due to lack of sufficient knowledge about their behavior. These industrial processes are mostly controlled by the human operator responsible for making the selection of fuzzy logic optimal parameters for controlling industrial processes. As we are witnessing the Fourth Industrial Revolution and the emergence of industrial Internet of things, it became possible to benefit from the power of the hardware of the work stations and to provide wireless connection using microcontrollers building intelligent and reliable online control system. The wireless control system is suitable for environment witnessing dusty weather and a lot of pollutants, due to which the maintenance is difficult and costly. The wireless LabVIEW control and monitoring system if it is decided to be used will be very useful to overcome problems and it can be regarded as the best solution. The use of Wi-Fi for data transmission between the control device using PIC18F6627 microcontroller and LabVIEW will be reliable and help-full to control and automation. There are many off-the-shelf PIC microcontrollers boards which can be linked to industrial communication protocols. This paper focuses on designing, testing and developing wireless connectivity through TCP/IP protocol between the SBC65EC board and LabVIEW and discuss design and implementation the wireless network between the LabVIEW and PIC18F6627 selected for its fast analog to digital converter, through TCP/IP Ethernet network for control and monitor purpose for Crude Oil Separator Industry.

I. Introduction

Online control systems through wireless networks will make production management and control of industrial processes more efficient and intelligent, thus improving product quality and reducing the cost of production and maintenance. In the process control applications wired intercommunication is mostly used in communication between control device and HMI. Anyhow PLC, SCADA and DCS are costly in addition to wired communication is difficult to implement in the desert and sandy areas. Wireless communication is emerging technology and finds lot of use in process industry. This technology can be used in areas where wired communication is cumbersome. This project is LabVIEW - PIC18f6627 monitoring and control system depend on the Wireless LAN as communication through TCP/IP Ethernet Protocol, software written in C programming language that make the PIC microcontroller work as mini web server.
