Abstract: This paper presents mitigating the effect of latency constraints on industrial process control monitoring over wireless using predictive approach. The study reviewed many literatures on the challenges of quality communication services in control system industries and identified latency as the major constraint which is caused by the behaviors of Remote Telemetry Unit (RTU) and Programmable Logic Controller (PLC). The system was implemented with neural network toolbox in Mathlab and then simulated. The result showed real time data monitoring performance of 22.05ms which is very good and within the in ISA100.11a, IEC 61850 and IEEEE 802.15 standards for industrial communication systems.
Keywords: PMU, RTU, Real time, PLC, ISA100.11a, IEC 61850 and IEEEE 802.15
I. INTRODUCTION
Industrial communication system (ICS) has dominated the industrial sector over the years, with the aim of ensuring interoperability between industrials plants, machines, computers, etc autonomously to achieve a process called industrial automation [1]. This has today remained an integral part of process design and control systems network. Basically there are two types of ICS which are the wired or wireless [2].
The wired based ICS uses network cables to connect the various process design equipments via surface or conduit wiring. This type of ICS have advantages such as low latency, immune to some environmental problems like as temperature and weather, closeness between process design, communication and control system, cheap to implement among other advantages; however, it also suffers certain limitations such as short circuit connection, accidental disconnection of cables, and corroded terminal due to environmental contamination among others.
Secondly, the use of wired communication systems are limited to only local area industrial network settings and cannot be deployed for the monitoring of remote off shore (off field or remote areas) based plants and machines as required in the oil and gas, power system, among other modern day industrials settings which requires long range remote monitoring of offshore plants, substations, oil rigs etc.
