, CHAPTER ONE: COMPUTER PROCESS CONTROL
1. Overview of computer process control
Computer process control is the study and application of automated control in various field of
engineering, remote monitoring software and system development, operation etc. in order to
maintain a process at the desired operating condition, safety and efficiently while satisfying
environmental and product quality requirement. Therefore, there are various applications of
computer process control in diverse areas of human endeavor and industries. These include:
Computer process control in an industry can actually improve safety and profitability of a
process.
In addition, the use of computer process control helps to reduce complexity in machine
operational process, speed up and enable high performance measurement of control system.
Computer process control is used in industrial continuous production, manufacturing
where some kind of material is produced without interruption.
Process control is used to automatically control condition in which products is made or
process being carried out with better quality and efficiency
1.1 Examples of computer process control are:
Continuous waste water and sewage management;
Remote monitoring, control, and management of oil and gas pipeline from control Centre;
Use of Fibre optics for long distance data transmission across country infrastructure
installation;
Milk pasteuring industries where sensors is used to provide monitoring feedback on
temperature reading and eliminate human error from manual process
Computer operating system performance process
Essentially, computer process control helps to eliminate human feedback and allow
advanced automated system to handle minor adjustment automatically without interaction
beyond human monitoring
1.2 Areas where computer process control can be used
1. Engineering to design reliable functional and operationally efficient system. It is used to
develop process control instrument for industrial operational staff to aid monitoring of
individual process.
, 2. Software and system development. Software and system development designers and
developers are typically responsible for software based system that interface the physical
machinery used for the process control. Software engineers work closely with other
professionals when developing process control system.
3. Quality assurance. This is required to catch errors and mistake, adjust the process and take
necessary action to ensure perfect product quality, safety and efficiency.
4. Operation personal such as supervisor and workers are responsible for monitoring process
control equipment to ensure that it is functioning properly, and without errors.
1.3 Benefits of computer process control
1. Increase system throughput without additional expenditure;
2. Increase automation, decrease human interaction;
3. Eliminate rework, scrap and inefficiencies. Control process helps to keep every system
operate at maximum efficiency, eliminate inefficiency and the need to rework and scrap
product;
4. Enhances your capability to take on more work;
5. Boost energy efficiency. Helps to utilize machinery at its full best and remove waste.
In recent time, one the technologies that drive process control in industries and at home is the
internet of things. Internet thing popularly abbreviated as IOT is the networked interconnection of
industrial and everyday objects equipped with some kind of intelligence to ubiquitously collect
and analyze real time data. Internet of things technology is composed of five main technologies
such as radio frequency identification (RFID), wireless sensor networks (WSN), Middleware,
cloud computing and internet of things software. In the next chapter, internet of things technology
features such as applications, components, characteristics and technologies that support its
implementation will be discussed in details.
