MAQOLA ANNOTATSIYASI

A review and analysis of known works on the automation of control and regulation-monitoring of the width of the working slots of the harvesting apparatus (НA) of the cotton harvester, in particular, the automation of control and regulation of working units, which determines the indicators of the quality of the harvest and the productivity of the cotton harvester, is carried out. It has been substantiated that in order to increase the efficiency of the functioning of the cotton picker, automatic control and management systems are needed that perform the functions of information-measuring and control systems that perform horizontal and vertical adjustment of the position of the harvesting device and adjust the working gap according to the agricultural background, inform the driver about other important parameters of the cotton picker and cotton-growing machine-tractor units (CGMTU). It has been established that one of the most important parameters to be monitored and regulated by the cotton harvester is the width of its working slot (WWS), which determines the productivity and quality of the cotton harvester collection. It was revealed that despite some progress in this direction, there is still a lot of research work to be done on the development of intelligent converters, sensors, instrumentation and control devices. At the same time, one of the main element and node that determines the accuracy of control and regulation of the width of the working slot is sensors that control and convert the width of the working slot into a different type of signal proportional to them, convenient for further use, which is an urgent issue. In this regard, the work considered and carried out a critical analysis of the principles of construction and operation, methods and sensors for controlling the width of the working slots (WWS), for example: contact with mechanical switches, inductive and potentiometric sensors with outputs of the controlled parameters to various display elements: numbered color lamps, displays, etc. The main characteristics, advantages and disadvantages of the considered sensors are given, as a result of which it is concluded that it is necessary to continue research and development in this direction
