Measures to reduce operator fatigue
In modern automated production, psychology and physiology of human operator occupy a key role. It is necessary to improve the working conditions and to establish the scientific basis, to ensure the proper working conditions, to organize the working schedule and to organize the leisure. Screen-operated exm operators are characterized by headaches, backbones, backbones, back pains, and fatigue. One of the most important measures to improve the conditions of work is the working status and work schedule of the worker. Job status. The work of the operator is essential in improving the working conditions. We added a working table. , as it will allow you to scroll the screen, keypad, and documents at any time. The desktop and eyelashes need to be proportional to each other. The height of the adapter is 42-55 cm. The working chair is selected according to the duration of the work: if it is processed for a long time, it can be used with a lightweight seat, a large chair, for a short period of time as it is easy to move.

Picure 4.1 demand for operator's work
Business route. Stopping the operation of the display operator prevents unnecessary safety and fatigue. During the working day, the employee's ability to work can not attain his highest value. When operating the screen with the operator, it may take up to half an hour to restart every 2 hours or take 15 minutes for 1 hour. This short-term restraint reduces fatigue and fatigue. In addition, the distance between the operator and the car, the magnitude of the screen magnitude on the screen, and the screen depth. The color of the eye and the screen is 60-80 cm, the size is 3-4 mm, the optimal width and height 3: 4, and the distance between the mark should be 15-20%.

Picture 4.2. Requires the operator to work on a computer
When designing the workplace, you should also emphasize the status of the display and the keypad on the table. The exm keypad in the graduation qualification works separately from the screen and complies with the terms of the workplace. The role of the operator is determined display joylashtirilayotganda eye and head movements of the viewing area is also planned. Its business is provided so that the operator, in this screen, in the midst of writing doqument the left approach or should joylatirgichlarda. The keyboard is relatively flat, with an average row height of 2.5 to 5.0 cm. The distance from the middle part of the keyboard to the tablecloth is 16 cm. Exms produce various x-rays from their workouts. Considering this, it is necessary to reduce the working time, as well as to use special protection screens. Working conditions in order to, sanitary and technical measures will be developed and hygiene among workers and labor norms, rules on propaganda work. Sanitation sanitary technolo- gies, intensified activities and provide healthy working conditions in production. For this purpose, the health of employees affected by such technological processes and equipment developed ways removing the gaps. As for the technical development of industrial enterprises to use the achievements of effective process for screening and prevention workers in hazardous work environments, equipment, placement of devices on the open air, you should check the contents of the gray labor as possible in jobs that require modern tools and equipment, administration, protection devices to use it. Ergonomics is also important in providing security in production. During the ergonomics of the man's work to create a comfortable, safe environment, improve labor productivity related facilities studied. If there are different types of processes and related equipment, the carrier model provides information, even if the operator is in a complex system. In order to accomplish this task, a model of information should be created, which means that the model should provide a timely description of the vehicle and, as a result, the operator should recheck and retrieve information without eradication, thought, and attention. Solution of complicated tasks depends on the operator's safety, precise quality of work, labor productivity, and the psychophysiological capacity of the person to comply with the information model. Biophysical compatibility describes the environment in which the operator's functional, normal physiological state is maintained. The power and energy of a human being have a definite limit. Therefore, fatigue in other routes of operation may lead to unpleasant consequences. The energy equivalent is an agreement of the machine with the optimum capacity of the operator, the power required, power consumption, accuracy and speed of movement. Space-anthopometric compatibility means the size of the human body, the possibilities of the external space, the operating state of the operator, the stability of the body. The exact position of the task determines the size of the work place, the operator's distance, height, interval, and other indications. In addition, the psychological function of the person is also important. Human ability and productive work depend on the level of psychological stress. It is assumed that the operator does not have a normal level of emotional and emotional stability of more than 40% to 60%, otherwise this will reduce his / her ability to work. Ventilation is of great importance in supplying industrial buildings with standard meteorological and sanitary-hygienic conditions, limiting the amount of harmful and toxic products in the workplace, further improving the working conditions, increasing labor productivity and safety. In the building, air, window, shutters, and lanterns can be easily and explicitly switched on so that air can be exchanged. Due to the large difference in winter and outside air temperature during winter, it is desirable to change the air in the building. Therefore, the surface of the protective windows is reduced and they are fitted at a height of 5-6 meters above the floor surface. In summer, it is enough to arrange the air flow at a height of 1.5-2 meters. Ventilation systems in the premises, rooms are started 10-15 minutes before the start and 10-15 minutes after the work is completed. Another condition that is consistent with sanitary and hygiene requirements is the degree of illumination of the room. Exposure to hypertrophied and illuminated rooms increases productivity, decreases tiredness, and ensures safety of the enterprise. The operator or worker who works in a well-lit room does not fit well and can not adapt to the production environment. As a result, labor productivity can be seen in labor activity. Excessive illumination also affects the image. The normal lighting of the room should be 400 lux. It is also important for the light to come from the workplace to the workplace. The selection of the types of lighting systems depends primarily on the technological process, category. To improve the worker's work, we need to focus on such factors as lighting, humidity, and ventilation, as we have mentioned above. Under normal circumstances the moisture content of the room should be around 60-70%. Considering the air exchange in the room, the ventilator should be installed in each room.
