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

FMEA Types and steps involved

FMEA means Failure Mode and Effects Analysis. There are 3 types of FMEAs.  System FMEA (SFMEA) Design FMEA  (DFMEA) Process FMEA  (PFMEA) SFMEA is for System and used to analyze the failures of the end product in a customer's system. It focuses on the potential failure modes associated with the functions of the end product.  DFMEA begins with the development of information to understand the system, subsystem or component being analyzed and defines their functional requirements and characteristics. It focuses on potential failure modes associated with the function of each system, subsystem or component being analyzed.  PFMEA is used to analyze manufacturing and assembly processes. It focuses on process inputs.  FMEA Processes - Steps Involved  There are 13 steps in creating an FMEA. Please find the attached diagram. Step 2: Define the Function  What is the system, the sub system or process steps supposed to d...

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...
