Basic concept
Office Automation (OA) is based on the gradual automation of equipment and communications through the Management Information System (MIS) ) is a comprehensive technology that emerged from the development of It is a new way of office that combines computer network with modern office. It can not only realize the automated processing of office affairs, but also greatly improve the efficiency of office affairs of individuals or groups, and provide a basis for the management and decision-making of enterprises or departments. Provide scientific basis. In the field of office automation management, if hardware technology is its environmental protection, then software technology is the soul for the smooth realization of various office automation functions. Since the 1970s, it has started with stand-alone processing. For example, microcomputers have been used to process text, and then complete tasks such as filing files, recording instructions, and automatically recording phone calls. After the 1980s, office automation entered a period of rapid development. Computers were commonly used in offices as high-level management tools, such as information retrieval, auxiliary decision-making, etc. Computer network systems consisting of office equipment, computers, communications, etc. were interconnected. , using network integration technology, people's ability to process office information has undergone a qualitative leap, and office automation has become a major symbol of intelligent buildings.
At present, the office automation system has become a comprehensive system including computers, communications, audio and video recognition, numerical calculation and management and other technologies. Computer technology, communication technology, system science and behavioral science are regarded as the four supports of office automation, and workstation (Work Station) and local area network (Local Area Network) have become the two pillars of office automation.

The six major application areas of computers are scientific computing (or numerical calculation), data processing (or information processing), assistive technology (or computer-aided design) and manufacturing), process control (or real-time control), artificial intelligence (or intelligent simulation), and network applications.
Scientific computing (or numerical calculation)
Scientific computing refers to the use of computers to complete calculations of mathematical problems raised in scientific research and engineering technology. In modern scientific and technological work, scientific computing problems are numerous and complex. By utilizing the computer's high-speed computing, large storage capacity, and continuous computing capabilities, various scientific computing problems that cannot be solved manually can be realized.
Data processing (or information processing)
Data processing refers to the collection, storage, organization, classification, statistics, processing, and utilization of various data A collective name for a series of activities such as , communication and so on. According to statistics, more than 80% of computers are mainly used for data processing. This type of workload is large and wide-ranging, which determines the dominant direction of computer applications.
Data processing has gone through three stages of development from simple to complex. They are:
Electronic Data Processing (EDP), which uses the file system as a means to achieve Individual management within a department.
Management Information System (MIS) uses database technology as a tool to achieve comprehensive management of a department to improve work efficiency.
Decision Support System (DSS), which is based on database, model library and method library, helps management decision-makers improve their decision-making level and improve the correctness and effectiveness of operational strategies. sex.
At present, data processing has been widely used in office automation, computer-aided management and decision-making in enterprises and institutions, information retrieval, library management, film and television animation design, accounting computerization and other industries. Information is forming an independent industry. Multimedia technology allows information to be displayed in front of people not only in numbers and text, but also in emotive sounds and image information.
Assistive Technology (or Computer Aided Design and Manufacturing)
Computer-aided technology includes CAD, CAM and CAI, etc.
Computer Aided Design (CAD)
Computer-aided design is a method that uses computer systems to assist designers in engineering or product design to achieve the best design results. kind of technology. It has been widely used in aircraft, automobiles, machinery, electronics, construction and light industry and other fields. For example, in the design process of electronic computers, CAD technology is used for architecture simulation, logic simulation, plug-in division, automatic wiring, etc., thus greatly improving the automation of the design work. For another example, in the architectural design process, CAD technology can be used to perform mechanical calculations, structural calculations, and architectural drawings, etc. This not only increases the design speed, but also greatly improves the design quality.
Computer Aided Manufacturing (CAM)
Computer-aided manufacturing is the process of using computer systems to manage, control and operate production equipment. For example, in the manufacturing process of products, computers are used to control the operation of machines, process the data required in the production process, control and process the flow of materials, and inspect products, etc. The use of CAM technology can improve product quality, reduce costs, shorten production cycles, increase productivity and improve labor conditions.
Integrate CAD and CAM technology to realize design and production automation. This technology is called Computer Integrated Manufacturing System (CIMS). Its implementation will truly enable an unmanned chemical factory (or workshop).
Computer Aided Instruction (CAI)
Computer-assisted instruction uses computer systems to use courseware to teach. Courseware can be developed and produced using writing tools or high-level languages. It can guide students to learn in a cyclical and progressive manner, allowing students to easily learn the required knowledge from the courseware. The main features of CAI are interactive education, individual guidance and individualized teaching.
Process control (or real-time control)
Process control is the use of computers to collect detection data in a timely manner and quickly automatically adjust or automatically control the control object according to the optimal value . Using computers for process control can not only greatly improve the automation level of control, but also improve the timeliness and accuracy of control, thereby improving labor conditions, product quality and qualification rate. Therefore, computer process control has been widely used in machinery, metallurgy, petroleum, chemical industry, textile, hydropower, aerospace and other sectors.
Artificial Intelligence (or Intelligent Simulation)
Artificial Intelligence (Artificial Intelligence) is a computer simulation of human intelligent activities, such as perception, judgment, understanding, learning, and problem solving and image recognition, etc. At present, artificial intelligence research has achieved a lot of results, and some of them have begun to move towards the practical stage. For example, expert systems that can simulate high-level medical experts for disease diagnosis and treatment, intelligent robots with certain thinking abilities, etc.
