Android OPC UA SCADA and Client

TeslaSCADA is a SCADA for accessing production and process data through smart phones and other Android devices, using the industrial communication standard – OPC Unified Architecture (UA).

Android OPC UA SCADA and Client

Quick visualization between an Android device and remotely situated industrial devices such as flow meters, compressors, tanks, artificial lift devices and more. TeslaSCADA allows the monitoring and control of automated processes to be extended to an ordinary mobile device, smart phone or tablet PC without extra development environment

Android TeslaSCADA

TeslaSCADA can be used in these industries: Home automation, Oil and gas, Water water management, Factories and production lines.Energy Control and Monitoring.

Tesla offers products and services in the field of automation industry and beyond. Based on OPC Unified Architecture technology we offer OPC UA SCADA and OPC UA Client for smart phones and Tablet PC based on Android platform.

Gadgets as Visual Interface for Process Control

Here is is gadget GUI for Industrial Process control, WebApps. The buttons make a sound and Light up internal LED lamps. Power On-Off control, Digital Timer; Start, Reset Scroll and Select are the controls.

An Image ScreenShot is here.

I will first make some simple examples with this UI. Then i will try to interface the javascript with PHP-MYSQL Application. I am just Thinking Loud. This makes a Globally Distributed Process Control Possible. :~) . You can Use html-js-php-msql. You can use ajax-python-perl too.

Digital Timer Gadget Visual Interface - Live Gadget Demo

But for now, back to earth, I will just complete some more simple tutorial gadgets. This Idea of mine is Open Source, please keep it that way.

The advantage is that the industrial process or Home automation can be monitored and controlled on any computer including tablets which has a Browser. The plant automation or Home appliance can be regulated even as you travel back from factory to home. Or in any city from the Cyber Cafe. A Wireless Lan and Computer with Browser is all you need.

Press The Power on-off for a soft start, this is to prevent the inrush current from stressing the javascript components. Then it goes to a display test. The Start button can run or stop timer by toggling. The reset will Bring timer to 0000, format is min-sec.

Set by pressing select to get a marker over orange digit, Use Scroll to set number. Press Start to start timer, Start to be off to set again. The buzzer will turn on when Time elapsed matches time set. and the alarm relay trips. And a Flashing Annunciator signals end of process. Now Reset will start process again and stop flashing LED.

To use this like a regular instrument, you need a small portable hand-held computer with browser. Fix that in a Cabinet by filing or grinding it to size and wire the relays and supply. :-)

Analog Bargraph Clock Gadget

Analog Clock, Linear Display of Time Elapsed using Bargraph, Shows Week Days and Month Days Passed.

The WD indicates Complete Week Days passed and MD is Month Days Completed.This is not the date, date is MD+1. This is an example of CSS Animation, that was the Motivation for this clock.

Reliability of Electronic Products

I have been in Product Design, Manufacturing and Marketing of Electronic Products/components. I have also been, like many of you, a customer.

It is very important that the customer gets a Reliable, Sturdy, Usable and Dependable product. This is what makes the Good Brands which in turn add to the Company Reputation and value.

The most important is the "Direct Customer Support" when a product fails or user finds it difficult to operate.  This include Prompt Product Service and Repairs. Any laxity or high-handedness or a Ping-Pong Customer Support can cause acute Brand Blindness that could even become Hereditary. Your brand can be shunned by a Family for generations and they also propagate negative marketing.

Your Product and Your Customer are like Family. Protect it and Nourish it for your own good.

The bathtub curve is widely used in reliability engineering. It describes a particular form of the hazard function which comprises three parts:

  • The first part is a decreasing failure rate, known as early failures.
  • The second part is a constant failure rate, known as random failures.
  • The third part is an increasing failure rate, known as wear-out failures.
  • The name is derived from the cross-sectional shape of a bathtub.

Engineering Poetry and Heuristics

Knowledge comes in Handy at every part of your Life. Entertainment should be Edutainment. Here is a collection of comments and blurbs i wrote around 2012 - delabs

Verify Again and Again

After doing something, Verify, ask a friend to crosscheck, verify again.

Wait there is more ...

Then ask somebody who does not like you so much, to check or test it and offer critical comments.

Otto, Manuel and Me

No these are not Modes of Operation in another tongue. I met these Gentlemen in an Online Ergonomics and Usability Hangout.

It was just Otto, Manuel and Me.

Whence Input Hence Output

If Inputs are Distorted, The Outputs are Noisy.
Even if the Amplifier is Very Good.

If Raw Materials are of Poor Quality, The Finished Goods are Defective.
Even if the Process and Machinery is State Of The Art.

If the Specifications are incomplete, The Prototype will be rejected.
Even if the Design and Tools are Perfect.
