Industrial IoT Application – Intelligent valves in IoT

 Industrial IoT Application – Intelligent valves in IoT

Objective:

To implement local intelligence in ICS (Industrial Control Servo) valve by measuring selected primary data and use it to calculate / infer useful derived data.


Primary data:
Pressure difference(∆𝑃) across the valve
Temperature at inlet and outlet(T1&T2)
Position of the servo piston

Derived data:
Mass flow / Capacity through valve
Life cycle estimation – wear & tear, number of operations

To implement connectivity in ICS valve
by creating a network layer & connect ICS valve for local & cloud interaction

Below is the block diagram of the IIoT application (figure 

Figure 1 IIoT Block diagram
Challenges:
•   Extreme temperature and pressure range(0 to 52 bar)
•   Presence of stray magnetic field.
•   Space, Design and cost constraints
•  Size of the system (sensor + signal conditioning + link       connectivity)
•   Presence of  highly reactive refrigerants (NH3)

Conclusion:
The prototype has been tested for its functionality and strength and finally it got placed in an actual IR system and verified the data acquisition and connectivity. Android based user interface is used to display the sensor information and derived data. If anyone interested to know more details of this application, please get back to me. Thank you

Anatomy of embedded Linux system

Linus Torvalds released 1st version of Linux kernel in 1991.  Much lower used as desktops and mainly used for embedded applications. In embedded systems, Linux has been ported to many architectures including ARM. It’s an open software, and some pros of open source software - reduces software costs, full control of source code, wide usage of components can improve quality, easy to evaluate new software. In the anatomy of embedded Linux system, these 4 items are very important - Tool chain, Boot loader, Kernel and File system. This is the basic diagram- we have 2 main components Host and Target.  Tool chain indicates the tools and software required for developing software on the target platform. Example compiler, Binutils, C library, debugger, kernel headers etc.  If we have to debug kernel headers, serial debugger can be used. If CPU wants to be debugged,  JTAG debugging tool must be used.  Please refer below image.  Binutils is a coll...

Introduction to Modelling and Simulation

What is about Today?    Modeling & simulation is use of the physical, mathematical or logical representation of a system , entity or process and these models  reduces the development time and cost of the system and it optimizes the design.  Simulation is the imitation of the real-world process or system. To simulate something, it requires a model to be developed, and these model represents the key characteristics, behaviors and functions of the selected system or process.Modelling an act of building a model and Simulation is act of using a model. Simulation software is based on the process of modeling a real phenomenon with a set of mathematical formulas.  Advantages: Allows to understand how the system operates in real-time system in virtual environment. Easy to make changes in to the system and their effect on the output. Can determine the system requirements by applying different configurations. Performing bottleneck analysi...

Introduction to latest technologies such as IoT, IoE, IIoT,WoT

Hi Everyone, Now-a-days, we are hearing terms such as IoT, IoE, IIoT, WoT. In this article i am trying to explain what exactly these terms means.  Let me start with fancy word called IoT (Internet Of Things). Its a world of things (such as vehicles, home appliances, any physical device) connected.  These devices embedded with firmware, software, electronics, sensors, actuators and connectivity which makes any physical device intelligent, so that they can talk with each other. Do you want to know why? I will be explaining more details in my next article. IIoT is Industrial IoT, i.e using IoT in manufacturing industries. This brings brilliant machines together, advanced analytics and many more. It has great potential to change the way how the Industry works and it enables M2M machine-to-machine communication. Next article i will tell some real time applications of this. IoE is Internet of Everything where people, process, data and things(these are ...
