SCADA – Supervisory Control and Data Acquisition

A Closed loop control system has a Sensor-Controller-Actuator. The Bimetal Thermostat has all the three in the Bimetal itself. The Sensor, the Relay Contact and the Intelligence. This is Process Control when implemented to control the temperature in a Bakery Oven.

This leads us to Sensors-Transmitter-Controller-Outputs-Actuators. Where each is an independent electronic/electrical component of an entire Process Control system. The Process could be Temperature, Pressure, Speed, or Level.

IntegraXor SCADA

IntegraXor SCADA  - Create the interactive graphical interface for multi-device compatibility.

Industrial Automation encompasses many such Process Control Systems to form a Engineered System Solution for an Entire production line with different stages and process types.

At the machine end, the control has to be real time and highly reliable, dedicated controllers both Analog and Microcontrollers based are used. Analog as a fallback/override/trip or backup controller in case Embedded system gets stuck/fails.

These controllers or transmitters also send the data of the process back to a center control panel room. The actuators and outputs also have an override from the control panel. Sometimes Intelligent controllers at machine end can be remotely tweaked/tuned by Control room. This is possible due to Embedded systems and Flash., It also can pose problems if misused. Using SCADA such networking of these process control systems and Monitoring, Tweaking, Data Collection and Analysis is possible.

Come Internet or Web and Wireless, the scenario changes entirely. The Control room stays where it is, the Tablets can Access and utilize the SCADA and entire plant at the machine end also. The Control room can be carried around with limited access. This evolves further to that extent that an expert engineer can check the status of the Product Line from any Web Browser and suggest remedial  actions to the others at the factory. He can even see the status on mobile devices. Now study the Resources below.

Industrial Process parameters, production flow or work status, material offtake, processing of products, incoming inspection status and quality process monitoring. All these need to be interfaced with the ERP and access to Mobile devices like Smartphones and remote Computers provided. This helps smooth micro management of a industry. Some Interfaces may have supervisory control and others just graphs and progress charts. Depending on the person and his work or machine area.

The data and presentation of complex data (by graphs and charts) enhances analysis and timely decision making. Then these solutions will be productive, and be an asset to an existing system. To ensure that; software or webware developers have to be supported by the domain experts having decades of hands on experience on the shop floor. Else; if it is built on theory and some statistics, the result may appear good and work well for small or standard configurations, but in demanding, changing, real life scenario, it may fail to deliver the best.

Analytical Instrumentation Technologies

Let us assume Physics, Chemistry and Biology as Verticals on a Horizontal plane called Science. A part of Physics developed into Magnetism and Electricity, which further evolved into Electrical Engineering a Technology. When a branch of Science is applied to develop, evolve and maintain Life on this Planet it becomes a Technology.

Electrical Engineering as a Technology has evolved and branched out into many specialized domains. With the coming of Semiconductors and the Advancements of Material Technologies, Electronics Engineering emerged as a foundation or a Horizontal for many new Verticals.

Analytical Instrumentation Technologies

One such Vertical is Instrumentation, here you know Industrial Process Control is one and the other is Test and Measurement. The third branch we learn about today is "Analytical Instrumentation Technologies" which is more like an Oblique, it Cuts thru Physics, Chemistry and Biology and many of its sub-branches. It also supports the areas called Life Sciences, Bio Technology, GeoSciences, Materials Science etc. .

Here i have posted some analytical instruments ... Laboratory Analytical, - Research and Lab Instruments, Bio and Earth Science. - EEMetric.com - Test and Measurement Instrumentation.

Start Learning -
(I Inherited some chemistry apparatus and chemicals from my grandfather. This lead to a Tiny Physical and Electro-Chemistry lab in the Store Room and later the Garage when i was at school. That is one of the reasons my website has the name delabs and i created a blog called "Analytical Bionics" around 2004. Later those posts were integrated in my other blogs.)

Uninterrupted Power Distribution for Homes

The Enhancement of Mains power system for Homes and Small Business is critical. The population is more now and the use of electricity for more appliances becomes inevitable, this makes power shortages imminent.

Power Electronics & Solar Energy

The power to Homes can be distributed by two types of phase lines (live), a common neutral and the usual earth. High Phase is for Heaters and Motors and some lighting too. This phase can be shut down on power failure, load management or over use. The other is the Green Energy line, a low current phase which never fails! It is used only for lighting and small and light electronic appliances. It is a limited energy line.

"Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services."


That means, so much kWhr for a month, beyond which the line will trip off for the month. This Green Line is augmented by solar, wind or tidal electricity. That way this Green Line is Uninterrupted, but Energy Limited. This will bring a sense of responsibility on the consumer, who will plan the usage of his Green Power Line carefully.

The other High Phase raw line can go off due to Black-out and Brown-outs, when there is a shut down or load balancing. This can also be energy limited at a higher threshold, depending on the number of people in the small business or home. Big Companies have their own Mini Power stations to manage the Power problems, Here also a Green Line can be provided in addition to the mini power stations.

The sensible and frugal, energy consumer can depend on his Green Line to manage his office or home, with no interruption of power. All Home users, Commercial Establishments, Factories and Companies have to become responsible, frugal and austere in the consumption of both electricity and fossil fuels. This not only saves the costs for the company, but the society (read customers) which is the environment they depend on, is also sustained.

Happy Healthy People means more Customers/Consumers, that implies Economic Growth and a Vibrant/Resilient Stock Market.

Power Electronics shows the way - Power Electronic Circuits.
