Industry physical processes of machines to create virtual

Industry4.0: It is current trend name of automation and dataexchange in manufacturing technologies. It contains Cloud computing, Internetof things, cognitive computing and cyber physical systems.

Cyber systems learnand control physical processes of machines to create virtual copy of physicalworld and make decentralized decisions. Through internet of things,cyber-physical systems communicate and cooperate with each other and withhumans in real time.Industrial 4.0 has certain design principles. Interoperability: Ability of sensors, devices andmachines to connect and communicate with each other through internet of things.

Information transparency: The ability of informationsystems to convert sensor data into high value digital data.Technical assistance: First, the ability of theassistance systems to aggregate and visualize data and make knowledgeabledecisions solving urgent problems in short notice there by helping humans. Second,cyber physical systems ability to conduct unpleasant or unsafe tasks to helphumans.Decentralized decisions: Cyber physical systemsability to make own decisions and perform tasks automatically.Modern technologies like big data analytics will helpearly prediction of defects and manufacturing failures, thus enabling theirprevention and increase productivity and quality that has significantcompetitive value. As more industrial big data sits on the floor all around theworld and manufacturing industry develops huge network, all these intelligentmanufacturing systems consider big data before going to make any decision whichhelps the systems to make more informed decisions.Internetof Things (IOT): It is network of physical devices, homeappliances and other items embedded with electronics, software, sensors,controllers and network connectivity which enables these objects to connect andexchange data. It allows objects to sense and control remotely through existingnetwork Infrastructure creating opportunities for more direct integration ofphysical world into computer-based systems resulting in improved efficiency,economic benefit in addition to reducing human intervention.

The background technology for Internet of things areclassified under their accessibility reach and form of connectivity.Short range wireless·        Radio-frequency identification: It useselectro magnetic field to read data stored in embedded tags of electronics.·        Wi-Fi: Local area networking whereelectronic devices can communicate through shared access point. Medium Range wireless·        LTE: High speed communication for mobilenetworks.Long range wireless·        Very small aperture terminal: Satellite communicationtechnology using small antennas for broadband data.Wired·        Ethernet: General networking standardusing fiber optic links and switches.·        Power line communication: Communication technologyusing electrical wiring to carry power and data.

Cyberphysical systems: It is mechanism that is controlled andmonitored by computer-based algorithms integrated with internet and its users. Examples:Autonomous automobile systems, process control systems and robotic systems.There is lot of research currently going in mobile cyberphysical systems. Mobile cyber physical systems include mobile robotics and othermobile electronics.

There is a huge scope for mobile cyber physical systemsdevelopment because of the following reasons.Many communication mechanisms such as Wi-Fi, Bluetoothto share data between interconnecting devices or internet. Multiple sensordevices and rapid development of Cyber physical systems programming languagessuch as JavaScript and C.
