Aiming at the problems of long response time and poor anti-interference ability of traditional vacuum nano-coating automatic control system, a design of vacuum nano-coating automatic control system based on AVR single-chip microcomputer is proposed. The use of ATmega128L microcontroller and Harvard architecture improves the parallel processing efficiency of the microcontroller. Select the transient voltage suppression diode to protect the power supply of the single-chip microcomputer, optimize the communication circuit, connect an external encryptor to realize the data encryption function, increase the filtering program and optimize the binary code processing function. Using PID (Packet Identifier) control algorithm, the design of nano-coating vacuum automatic control system based on AVR single-chip microcomputer is realized. Compared with the traditional system, when the simulation model and system parameters of the control system constructed in the environment change, the proposed system can be stabilized within 15 seconds, and can be stabilized for 13 seconds after the interference signal is added. The response time of the system is longer. Shorter, stronger anti-interference ability, more suitable for automatic control of vacuum nano-coating.

Prototype Test

This paper developed an automatic control system for folding arm awning based on environmental factors, which can overcome the disadvantages of the traditional awning of unitary control mode and low level of intelligence. The system consists of sensor unit, controller, drive motor and transmission mechanism. The sensor unit is used for testing light intensity, wind speed and rain, then an AT89S52 SCM single-chip microcomputer which is the core of the controller is applied to receive testing signal and send instructions to AC motor to realize the extending and withdrawing state of the awning according to the corresponding control logic. Meanwhile, this system is able to switch from automatic control to manual control so as to deal with power outage and other special situation and maintain operation of awning. The results of the prototype test show that this system is running steadily and can adjust the working condition of the awning in time according to the environment change. Compared with the current electric awning, the intelligent folding arm awning controlled according to environmental factors can achieve more energy conservation and environmental protection.

The thesis researched and designed a solar air heating automatic control system. The system is based on the AT89C52 single-chip microcomputer. The system has automatic tracking function control of the blade heat collector, winter and summer function conversion, and active and passive function conversion functions. The advantage of this system is that it can set the operating parameters of the system as required and can typically work following the set mode under complicated weather changes. Through experimental research, it is found that the solar air heating automatic control system can effectively improve the utilization efficiency of solar energy.

Automatic Removal

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.
