Process Parameter Estimation Oriented Industrial Wireless Sensor Networks: A Sequential Approach

Process parameter estimation, to a large extent, determines the quality of the industrial production. Traditionally, limited sensors are deployed in production field by elaborate wiring, which cannot provide the accurate estimate in the hostile industrial environment. Recently, industrial wireless sensor network (IWSN) has been considered as one promising technology to improve the process parameter estimation by deploying more sensors flexibly and making them work collaboratively. In this paper, a sequential IWSN (Seq-IWSN) approach is provided for the temperature estimation of the steel slab during the hot strip milling process. In Seq-IWSN, the network deployment and scheduling strategies coupling with the process parameter estimation algorithm are involved.


System Architecture

Project Overview
In this paper, we exploit IWSN to enhance the temperature estimation of the steel section for harsh processing process. Related outcomes can likewise be received for other genius cess stages or other modern process parameter estimation situations. To evaluate the temperature of the steel piece some time recently it enters the harsh plant faces a few difficulties. In the first place, the steel chunk moves along the exchanging table. Subsequently, the arrangement what's more, coordination of IWSN should adjust to the development to guarantee that the section can be inspected and the system can be fittingly worked. Second, the temperature condition of the steel section is time-changing. To secure the exact estimation before unpleasant processing, the IWSN ought to be fit to persistently track the temperature of the piece when it moves along the table.

Sample Code
NS_LOG_INFO ("Create channels.");
LrWpanHelper lrWpanHelper;// Add and install the LrWpanNetDevice for each node
// lrWpanHelper.EnableLogComponents();
NetDeviceContainer devContainer = lrWpanHelper.Install(nodes);
lrWpanHelper.AssociateToPan (devContainer, 10);
std::cout << "Created " << devContainer.GetN() << " devices" << std::endl;
std::cout << "There are " << nodes.GetN() << " nodes" << std::endl;
/* Install IPv4/IPv6 stack */
NS_LOG_INFO ("Install Internet stack.");
InternetStackHelper internetv6;
internetv6.SetIpv4StackInstall (false);
internetv6.Install (nodes);
Code Explanation
This code explains how we are creating channels and getting attached withe devices.Internet stack creation also done with the assignment of ipv4 addresses.
