The Need for an Embedded Processor

The upgrade project consisted of the design & construction of a new Programmable Logic Controller (PLC) and Supervisory Control And Data Acquisition (SCADA) system to eventually replace the existing legacy Honeywell/Experion system and equipment which is nearing the end of its life cycle. The new chemical sludge handling PLC, incorporates hot standby Siemens S7400H processors utilising a Media Redundancy Protocol (MRP) remote Input/Output (RIO) network allowing simultaneous PLC and network failure without process interruption.

Old in the days, computers were huge in size, hence, not that powerful and relatively slow when compared to computers nowadays. A computer is a complex electrical integrated circuit connects multiple of electrical components together. These components could be summarized in the following; transistors, resistors, capacitors, and diodes. Therefore, when it comes to high tech computers, revolutionary quality is a serious matter. One of the computer quality standards, for example, is the speed at which a computer carries out calculations, this speed is determined by transistors speed. The faster the transistor the better the computer.

if an attacker manages to enter the SCADA network, it will be difficult to carry out any sort of attack. The monitoring

The control system of the automated warehouse include management/monitor computer, master PLC and lower PLC, which are connected by Modibus and wireless networks and can build up a complete multilevel computer monitoring system, as shown in Figure 2.2. The whole automated warehouse system integrated cargo storage, retrieval, distribution and transportation together, realizes intelligence operations in the whole system, and is an intelligent warehouse without any manual operation.

Everyday businesses here at The Best Widget Incorporated involves working with various types of data. The need to manage the data to ensure that it is accurate while also ensuring that if follows and necessary laws is a requirement. To assist in ensuring all data is accurate and properly collected the use of data capture system will need to be deployed.

When conducting operation functions in any organization, a set of rules and common procedures must be abided by to ensure that the highest level of consistency and accuracy is maintained. The receiving of Raw material can be improved upon by reducing the paper load that one would have to follow just to be able to track and store data from the point of shipping to unloading the raw materials at a factory. By creating a new system

Describe the steps to be taken prior to inputting the data into the computerized system and how you would go about implementing the new system.

In this following assignment, we will be developing monitoring systems for Suzlon Energy India. The assignment is focused on an efficient development of a monitoring system.

In the last decade there was an overproduction of coffee. Prices of coffee beans plummeted when the quantity supply of beans exceeded the quantity demanded, causing the surplus. Before the 2008 Recession, the economy was growing and people wanted to get the best coffee for their buck. Since the U.S economy was expanding, gourmet coffee suppliers wanted a cut of the money, so gourmet retailer shops started popping up. Coffee retailers were fairing pretty well in the market, and remained strong during and after the 2008 Recession.

Ever since technology was discovered, it has progressed its way throughout history. From the electrical relay to iphones, it is obvious that there will be more pieces of technology to come. As a matter of fact, one invention that will be coming soon is the human microchip. This chip that contains information about an individual will be implanted into their brain. Although some people are with this idea, others oppose of it. The government shouldn’t allow implanting a microchip into one’s brain because of invasion of privacy, posing a threat to one’s health, and making them a prime target for people with bad intentions.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

Before developing the new system we have to look for existing system and what were the advantages in it and which were the reasons that forced to develop new system. In this chapter we will discuss about these in detail.

Abstract— clean air is a basic necessity for all human beings living on earth, yet about 80% of world’s population breathes air that has pollutants which exceed the World Health Organization’s recommended level. Environmental air pollution has significant influence on the concentration of constituents in the atmosphere leading to effects like global warming and acid rains. To avoid such adverse imbalances in nature, an air pollution measuring system is of utmost importance. This paper presents fault detection and isolative model implemented in a novel fault tolerant microcontroller based data acquisition system design for air pollutant concentration measurement in industrial facilities in Nigeria. A supervisory control unit was incorporated in the data acquisition system design in an attempt at robust control. The model utilizes weighted standard deviation /data variance method to detect anomalies and correlation in measured data, with a view to data intelligence elicitation, an error residual generator was designed to handle fault isolation and accommodation. The overall system implements corrective procedures in the event of a fault or failure with appropriate indicators showing in-process operation.

On systems that perform real-time processing of data, performance is often limited by the processing capability of the system [1]. Therefore, in order to judge the efficiency of any system it is very important that we evaluate the performance of the architectures based on which the system is being built. We can also state that we can make a system more efficient and more capable by working upon the algorithm on which the system is being built. The more efficient the algorithm is the more efficient will be our system and vice versa. It is assumed that the way in which this chapter is written will provide the source of motivation for the thesis, it will also give an insight of the work which is done and it is organized in the thesis.
