Supervisory Control and Data Acquisition.\n\nThe system provides reliable data collection and continuous real-time control in a user-friendly environment. In Layman’s terms, the system is designed to supervise the flow of sewer water through the pump stations, and to perform certain functions, such as shutting off or turning on certain pumps, etc. The system consist of telemetric stations mounted on the individual pump and control stations and water tanks, water treatment and cleaning plants, and a dispatching center made up of one or more computers installed at the central dispatching facilities. Data transmission takes place using portable means, typically radio data networks, GSM or phone.

Mechatronics is the synergistic combination of mechanical engineering ("mecha" for mechanisms, i.e., machines that 'move'), electronic engineering ("tronics" for electronics), and software engineering. The purpose of this interdisciplinary engineering field is the study of automata from an engineering perspective and serves the purposes of controlling advanced hybrid systems.

This is evidently in reference to a computer simulation project\nwhere students had to write a program simulating a shuttle bus\ndispatch service.  "Ticks" refers to the tick of an arbitrary clock\nwhich initiates re evaluations in the system.  SSS stands for "simple shuttle system".

A computer system is the combination of hardware and software. A typical computer system has memory and set of states that define the relationship between the systems inputs and outputs.\n\nAlthough in earlier times the personal computer or PC was an example of a computer system, in practice a person considered a Computer Systems Engineer these days deals with a range of different computer architectures.\n\nEven the simplest computer classifies as a computer system, because at least two components (hardware and software) have to work together. But the real meaning of "computer system" comes with interconnection. Many computer systems can interconnect, that is, join to become a bigger system. In industry these days the interconnection of Variable speed drives and Programmable Logic Controllers (PLC's) to automate production lines and control motors is a common example of a computer system.\n\nInterconnecting different computer systems can prove difficult due to incompatibilities. Sometimes these difficulties occur due to incompatabilities between differing hardware and sometimes between differing software. Technically knowledgeable people can configure disparate computers to communicate using a set of rules and constraints known as protocols. Protocols attempt to precisely define the communication within and between computing endpoints. If two computer systems define the same protocols, they may be capable of interconnecting and become a part of a larger system.\n\nCommon computer system communications protocols include: Asi Profibus Modbus Canbus RS232 RS485\n\nEthernet based communications are also emerging as a computer systems communication protocol\n\nRetrieved from "http://en.wikipedia.org/wiki/Computer_system"

In information technology and telecommunications, the term configuration management or configuration control has the following meanings:\n\nThe management of security features and assurances through control of changes made to hardware, software, firmware, documentation, test, test fixtures and test documentation of an automated information system, throughout the development and operational life of a system. Source Code Management or revision control is part of this. \nThe control of changes, including the recording thereof, that are made to the hardware, software, firmware, and documentation throughout the system lifecycle. \nThe control and adaptation of the evolution of complex systems. It is the discipline of keeping evolving software products under control, and thus contributes to satisfying quality and delay constraints. Software configuration management (or SCM) can be divided into two areas. The first (and older) area of SCM concerns the storage of the entities produced during the software development project, sometimes referred to as component repository management. The second area concerns the activities performed for the production and/or change of these entities; the term engineering support is also often used to refer to this second area. \nAfter establishing a configuration, such as that of a telecommunications or computer system, the evaluating and approving changes to the configuration and to the interrelationships among system components. \nIn distributed-queue dual-bus (DQDB) networks, the function that ensures the resources of all nodes of a DQDB network are configured into a correct dual-bus topology. The functions that are managed include the head of bus, external timing source, and default slot generator functions.

The word "SCHEMA" means BLUEPRINT. N/w schema, though not a standard term, it means the set of rules which have been laid to implement the n/w being talked about.\nThe Schema is designed on the basis of the protocol suit being used.\n\nIf you have heard about the Conceptual schema, etc in DBMS, this is similar to that; diff being in the technology ref to.

Star-delta systems, as they are known in Great Britain and Europe, (transformers, motor starters, line reactors, electrode boilers etc) are essentially the same as what America refers to as delta wye systems, the only difference being in geographic terminology. \nThe phrase refers to two connection methods of a device in a three-phase electrical system: an example would be a distribution transformer with a delta primary, running on three 11KV phases with no neutral or earth required, and a star (or wye) secondary providing three 240v phases and an earthed neutral point.

A couple of good questions to ask yourself when designing a control system are...\nWhat is the minimum amount of control required?\nWill you ever have to expand this system, and what are the odds of that happening in the lifetime of the new control? (Based on the answer to this question, it may be wise to select a control that's more expandable than the minimum requirement.)\nWhat hardware, software, and training are going to be required to support the new system?\nWhat level of support do you currently get from the automation OEM's that you are considering?
