AUTOMATION: Introduction of HMI
http://ravi-softwares.blogspot.com/2009/08/introduction-of-hmi.html
Examples of embedded systems. Basic of Embedded system. User interfaces of HMI. PLC compared with other control systems. However it is abbreviated, the terms refer to the 'layer' that separates a human that is operating a machine from the machine itself. In some circumstance computers might observe the user, and react according to their actions without specific commands. A means of tracking parts of the body is required, and sensors noting the position of the head, direction of gaze and so on have be...

AUTOMATION: Wireless SCADA System
http://ravi-softwares.blogspot.com/2009/08/wireless-scada-system.html
Examples of embedded systems. Basic of Embedded system. User interfaces of HMI. PLC compared with other control systems. Wireless media can also be a communication medium for the master unit and the remote unit. Systems using this type of media are termed "wireless SCADA systems." A few examples of wireless media are explained below. Spread Spectrum Radio -. This is an electromagnetic transmission with frequencies of 175MHz-450MGz-900MHz. Special antennas are required to receive these signals.

Examples of embedded systems. Basic of Embedded system. User interfaces of HMI. PLC compared with other control systems. Basic of Embedded system. Since the embedded system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale. In general, "embedded system" is not an exactly defined term, as many systems have some element of prog...

AUTOMATION: SCADA Systems
http://ravi-softwares.blogspot.com/2009/08/scada-systems.html
Examples of embedded systems. Basic of Embedded system. User interfaces of HMI. PLC compared with other control systems. SCADA comes under the branch of Instrumentation Engineering. The term SCADA stands for Supervisory Control And Data Acquisition. Scada systems are used for controlling and monitoring chemical or transport processes and can be used in a factory environment such as electic power generation, water supply systems, gas and oil pipelines or any other distributed processes. The RTUs and PLCs ...
