1.1. Concept: information and computer science. The impact of media on the senses. Types of computer information

Concept: information and computer science

Information- (from the Latin word Informatio explanation, presentation). Initial - information transmitted by one person to another person orally, in writing or in some other way (for example, using conventional signals, using technical means, etc.), as well as the process of transmitting or receiving this information itself.

Computer science, a discipline that studies the structure and general properties of scientific information, as well as the patterns of its creation, transformation, transmission and use in various spheres of human activity.

Due to the presence of five sense organs in humans, information about the environment comes to a person constantly. Vision provides the most information. If the eyes are open, then a huge amount of information comes through them about the shape and color of objects, where they are, and even how they move.

Conclusion:

¨ All information coming to a person consists of signals.

¨ A person receives these signals, processes them and either executes them or remembers them.

The impact of the media on the senses.

A person is designed in such a way that he protects himself from unnecessary, incomprehensible and unpleasant information. She walks past him. In this case, a person does not process it, which means he cannot remember and turn it into knowledge.

Information that cannot be understood and assimilated is called information noise.

Conclusion:

1. It is difficult for a person to consume information. He can only do this in very small portions. Any overload turns into information noise, and... it becomes useless, that is, it does not turn into knowledge.

2. It is difficult for a person to process information. This makes him tired.

3. Man, we can make mistakes. Due to information noise, we can incorrectly process information and turn it into false knowledge.

4. A person is biased (i.e. he perceives information not as it is, but as it seems to him). If the information coincides with his personal opinion, he accepts, processes and assimilates it very easily. If information is unpleasant to him, he assimilates it with great difficulty and much remains unattended.

5. A person cannot store information for a long time. If you do not consolidate knowledge with constant exercises, information is forgotten very quickly.

What is a computer?

A computer is an electronic machine that can:

¨ Receive information;

¨ Process information;

¨ Keep information;

¨ Give out information.

As was previously said, humans also have these functions. However, he does this slowly, sometimes with mistakes and not always willingly. A computer frees us from the need to process mountains of information, but it does it quickly, reliably, produces it in a form that is convenient for a person, and stores it indefinitely.

/ Automated information processing and control systems (ASOPI)

Information technologies (IT) occupy an important place in all spheres of human life and activity. A special place in the diversity of IT is occupied by automated information processing and control systems (ASOIU), the main purpose of which is the automation of activities related to the storage, transmission and processing of information. Since information is the most important resource in the modern world, automated information systems play a decisive role in any field of activity (accounting, banking, warehouse, administrative and management automated systems). Modern automated information systems rely on the use of local and global networks, processing of graphic, video and audio information, multimedia technology, and artificial intelligence systems. Without this kind of systems it is difficult to imagine a modern enterprise, regardless of the size and direction of activity.

Automated information processing and control system (ASOPI)

Introduction

The use of modern computer information technologies is one of the main conditions for the effective operation of enterprises. Computers are widely used for automated information processing in science, education, industry, agriculture and other industries. In the energy industry, automated information processing and control systems (APICS) operate at various levels of management of energy facilities: they collect, digitally process and store signals and processes, transmit information through various communication channels, and are used in expert diagnostic systems, for modeling and decision-making.

In this work I will consider the main methods of automation and transformation of information, the creation and implementation of ASKUE, ASOIU, automated workplace.

Basic concepts, principles and methods of automation

Automation in general is a set of actions and measures of a technical, organizational and economic nature, which makes it possible to reduce the degree of participation or completely eliminate the direct participation of a person in the implementation of a particular function of the production process or management process.

Automated information technology (AIT) is a set of methods and methods for collecting, transmitting, accumulating, storing, searching and processing information based on the use of computer technology and communications. The main task of modern information technologies for organizational management is the timely provision of reliable, in the required amount of information to specialists and managers for making informed management decisions. computer information automation

Automated information system (AIS) is a human-machine system with automated technology for obtaining the resultant information necessary for information services to specialists and optimization of the management process in various spheres of human activity.

Carrying out automation of the work of economic services implies the construction of some kind of automated control system based on AIS. An automated control system (ACS) is a control system built on the basis of the use of computer technology, economic and mathematical methods and information technology.

Mass design of AIS required the development of unified theoretical principles, methodological approaches to their creation and operation, without which the interaction of various economic objects and their normal functioning in a complex national economic complex is impossible.

Scientific and methodological provisions and practical recommendations for the design of automated systems have now emerged as the fundamental principles of creating an automated information system: consistency, development, compatibility, standardization and unification, efficiency.

The principle of consistency is the most important in the creation, operation and development of AIS. It allows you to approach the object under study as a single whole; on this basis, identify diverse types of connections between structural elements that ensure the integrity of the system; establish the directions of production and economic activity of the system and the specific functions it implements. The systematic approach involves conducting a two-aspect analysis, called macro and micro approaches.

In macroanalysis, a system or its element is considered as part of a higher order system. Particular attention is paid to information connections: their number is established, those connections that are determined by the purpose of studying the system are identified and analyzed, and then the most preferable ones are selected that implement the given target function. In microanalysis, the structure of an object is studied, its constituent elements are analyzed from the point of view of their functional characteristics, manifested through connections with other elements and the external environment. In the process of designing an AIS, the systems approach allows the use of a mathematical description of the functioning, the study of various properties of individual elements and the system as a whole, and the modeling of the processes being studied to analyze the operation of newly created systems.

AIS control is characterized by a multi-level hierarchy with vertically subordinate elements (subsystems). The advantages of hierarchical structures have contributed to their widespread use in management systems. Thus, the hierarchical structure creates relative freedom of action over individual elements for each level of the system and the possibility of various combinations of local optimality criteria with the global optimality criterion for the functioning of the system as a whole. It provides relative flexibility of the control system and the ability to adapt to changing conditions; increases reliability due to the possibility of introducing elemental redundancy and streamlining the directions of information flows.

The practical significance of the systems approach and modeling is that it allows, in a form accessible for analysis, not only to reflect everything essential that interests the creator of the system, but also to use a computer to study the behavior of the system in specific, specified conditions. Therefore, the creation of AIS is currently based on a modeling method based on a systems approach, which makes it possible to find the optimal variant of the system structure and thereby ensure the greatest efficiency of its functioning.

Creation and implementation of ASKUE

Currently, the creation or modernization of automated systems for commercial metering of electricity (ASCAE) is a mandatory requirement when working in the wholesale electricity market.

To comply with the procedure for accounting for electrical energy and power supplied to an enterprise and accounting for all tariff groups of consumers established in the contract for the use of electrical energy, the developed automated systems for commercial metering of electricity (ASKUE) have to be placed directly with consumers and create complex hierarchical structures.

The development of technical projects for the automation of electrical energy and power metering for industrial enterprises is impossible without careful consideration of the issues of selection, placement and installation of ASKUE technical means, devices for collecting and transmitting information, and this should, as a rule, be carried out by employees of specialized industry design institutes.

Despite the fact that automated systems for commercial metering of electricity are created on the basis of standard metering devices, the unified "Standard technical requirements for means of automation of control and metering of electricity and power for ASKUE of power systems", approved by RAO "UES of Russia" on October 11, 1994, their use for financial settlements for consumed electrical energy and power for each enterprise has its own specific features. In this regard, in the design work, special attention is paid to the development of the section “The procedure for determining the consumption of electricity and power for settlements with the consumer of the ASKUE”.

An important element of information collection is dispatch control of actual electricity consumption and tracking deviations from the schedule.

The system, which may be widely used in the future, is a hierarchical structure where the number of levels is practically unlimited. Wired, fiber optic and wireless technologies are used as communication systems. To meet the needs of various objects, you need a single base software that has equal levels of functionality, reliability and security. It is also necessary to have several platforms that allow you to adapt the system to a specific object. Next, it is necessary to make the transition to systems focused on meters with new interfaces that have appeared from a number of manufacturers.

One of the most important areas of activity for equipment manufacturing companies should be the development of a multifunctional meter. This device must combine the functions of a 0.2S class electricity meter, a telemetry sensor, a power quality meter and analyzer and a digital oscilloscope. In addition, the device must keep an event log, which will solve most of the problems currently facing market participants in the field of commercial and technical accounting.

Automated processing systeminformation and management (ASOIU)

The basis of the electric power industry is an integrated energy system that carries out the technological process of electricity production, transport and distribution.

The main aspect of management is operational control of operating modes (operational - current). The main task is reliability of supply.

ASOIU as a system consists of a large number of elements at various levels and for various purposes. These include subsystems, modules, control units, tasks, management procedures, functions, operations, etc. Basic systems, as a rule, are hierarchical structures, ultimately consisting of elementary management procedures intended for inclusion in the automated control system.

Integration involves combining and coordinating management functions and procedures so that the optimization of its behavior is ensured during the enterprise management process.

Integration is manifested in all functional and supporting subsystems without exception.

In the technical support subsystem, these are local computer networks and ensuring communication between the enterprise and the external environment through global networks. In the information support subsystem, this is the maintenance of databases controlled by a DBMS. The integration of mathematical software is manifested, first of all, in the coordination of inputs and outputs of mathematical models, the integration of various models (for example, forecasting and planning), the integrity and consistency of the system of mathematical models. Software integration is manifested in the fact that it is built in the form of a complex and at the same time flexible software package that allows you to execute programs in the required sequence and in the required combinations. Integrated ASOIU, built on the basis of one basic one, takes the enterprise to a new level of integration of organizational support due to the unification of the user interface. This effect is especially noticeable in large automated control systems, where a new system replaces hundreds of old local systems. The practical result of the transition to a new system is a uniform enterprise-wide standard for how users interact with the system.

The main reason why automated systems are created at enterprises is functional integration. Enterprise management systems, production automation, product design automation and technological processes are combined into integrated computer production.

A unified computer system allows for mutual transparency of systems. For example, already at the design stage it is possible to simulate the possible impact of design and technological solutions on the production process.

The system is integrated with objects and systems located outside the enterprise. Integration between subsystems is the first step towards integration within. It is expressed in the exchange of data between subsystems. Often this data initiates events and processes in other subsystems.

Flexibility in the implementation of specific control structures gives rise to new aspects in the integration of the functions of the base system, since the composition of the functions included in the subsystems of a particular automated control system may not completely coincide with the functional content of the subsystems of the base system.

ASOIU is built with a focus on managing the production process as a single whole, and not on automating the activities of individual departments involved in management. Thus, comprehensive management automation helps to overcome barriers between various management services.

Workplace automation (AWS)

With the help of the implementation of AIS, comprehensive management accounting and analysis of the production and economic activities of the enterprise is organized, and the reliability and efficiency of the information received and used in management and analysis is achieved.

Prerequisites for automation of work are:

· successful computerization of management departments of the enterprise;

· the presence of a local computer network connecting users’ computers and providing access to common databases;

· implementation of an automated production resource planning system, which allows the use of management accounting data for analysis and forecasting of production and economic activities.

Typically, information is subject to some transformation procedures, but in some cases some procedures may be missing. The sequence of their implementation also varies, and some procedures may be repeated. The composition of the transformation procedures and the features of their implementation largely depend on the enterprise itself, which carries out automated information processing.

Performing basic procedures for converting information includes some mandatory steps: collection and registration, transfer, processing of information .

When collecting and recording information, special importance is attached to the reliability, completeness and timeliness of primary information. At an enterprise, information is collected and recorded when performing various operations; the collection of information must be accompanied by its registration, i.e. fixing information on a material medium (document, computer medium), entering it into a computer. Entry into primary documents is carried out manually, so collection and registration procedures remain the most labor-intensive.

In conditions of partial automation of management - the state expected after the implementation of AIS, special attention is paid to the use of technical means of collecting and recording information, combining operations of quantitative measurement, registration, accumulation and transmission of information through communication channels, input directly into a computer to generate the necessary documents or accumulation of received data in the system.

The transfer of information is carried out in various ways: using a courier, sending by mail, delivery by vehicles, remote transmission via communication channels using other means of communication. Remote transmission via communication channels reduces data transmission time, but its implementation requires special technical means, which increases the cost of the transmission process. It is preferable to use technical means of collection and registration, which, automatically collecting information from sensors installed at workplaces, transfer it to a computer for subsequent processing, which increases its reliability and reduces labor intensity.

Both primary information from the places of its origin and the resulting information in the opposite direction are transmitted remotely. Information is received via communication channels at the processing center in two ways: on computer media or directly entered into a computer using special software and hardware.

Information processing is carried out on a computer, decentralized, in places where primary information occurs, where automated workstations for specialists of a particular service are organized.

Processing can be carried out not only autonomously, but also in computer networks, using a set of software tools and information arrays to solve functional problems.

In the course of solving problems on a computer, in accordance with the machine program, result summaries are generated, which are printed by machine on paper or displayed on the screen. Printing summaries may be accompanied by a replication procedure if a document with the resulting information needs to be provided to several users.

It is planned to use decentralized means of collecting and preprocessing data, which is achieved using client-server technology, which allows the system to function in multitasking and multi-user mode.

The resulting automated analysis should include the following functions:

· analysis of the enterprise's activities;

· analysis of the use of production resources;

· analysis of financial consequences;

· feasibility study;

· balance forecast;

· cash flow forecast.

During the design of AIS analysis, the following work is carried out:

The composition of indicators necessary to solve problems, their space-time characteristics and information connections are determined;

Various classifiers and codes are being developed; the possibility of using national classifiers is being studied;

The possibility of using a unified documentation system to reflect indicators is identified, forms of new primary documents adapted to the requirements of machine processing are designed;

An information fund is being organized; the composition of the database and its organization are determined; forms for outputting processing results are designed.

When creating an automated information analysis system, the following work is performed:

· The composition of tasks and a system of indicators for each level of processing (individual workstations, local computer networks, distributed networks) are determined.

· The composition and methods of information exchange between different levels of processing are established.

· An information fund is being created and distributed among processing levels.

· Various forms of information input on a computer are created, taking into account multi-level data processing.

· Issues of using various types of classifiers are considered and the compilation of local information classifiers is provided.

· Various forms of information output are created.

· Issues of information and reference services for users and the construction of standard request forms are being developed.

· Automated information technology is being created to ensure direct user contact with the computer.

· Issues of organizing computerized office work for management activities and control over the execution of documents are being studied.

· Information interaction with the external environment is created based on the organization of e-mail.

Thus, automation of analysis work is carried out in a complex, as an integral part of a unified automated information system of the enterprise, which also includes an automated production resource planning system.
