Abstract. Combined with the Jiangbei wastewater treatment plant project in Yushu city, Jilin province, China, the design scheme, the system and the function for the automatic control system were summarized. The problems of the great change of water quality and quantity, dissatisfaction of design load and other issues existed in WWTP were solved. From the aspects of control strategy and microbial reaction mechanism, etc., the energy consumption for each processing unit under the control of automatic control system was analyzed. And the system performance and power consumption were evaluated by the WWWP’s operation results. The results show that: the quality of effluent is stable and the energy saving effect is remarkable by the use of automatic control system.

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.

On the basis of the computerized technological process control of sewage treatment in a urban sewage treatment plant in the Zone of Nanning, the author had brought forward a plan of PROFIBUS that based on automatic control system for sewage treatment, and designed the automatic control system diagram and the PROFIBUS network diagram for sewage treatment plant. At the same time, the author also made a study of techniques to control the sewage aeration, which was the most difficult problem in sewage treatment process. The fuzzy controller could indicate the changes of the water quality in treated sewage, effectively controlled the volume of aeration and then cut down the operation costs,it had produced good economic and social benefits.

Commercial means of automatic control system of electricity metering, as is known, are installed on the input switchgear and measure the power consumption of all electrical consumers of this metering facility. Such data do not give a complete picture of electricity consumption on each floor of the metering facility, which in turn does not allow the implementation of energy saving measures. Also, these metering systems for electricity metering have a high cost. The article proposes a method of data processing and transmission to the server with their subsequent analysis of power consumption on each floor of the object under study using the ARDUINO microcontroller. Such an accounting system has a lower cost than an automatic control system of electricity metering industrial production. The article presents the scheme of implementation and types of current and voltage sensors. The topology of the measuring complex is also considered in the article. Such a topology can expand and keep not only the general account of a concrete floor, but also in the generality of each educational audience separately. Collecting such data on electricity consumption, it is possible to conduct a qualitative analysis of rational electricity consumption in the educational process, it means that for example in sufficient natural light artificial lighting in the classroom does not need to be used, or after laboratory tasks in a computer class, computers there is still some time. The introduction of energy-saving housing is performed due to the comparative characteristics of the power of gadgets, laboratory stands, etc. with the number of students in the group in accordance with the approved educational process. The algorithm of data processing, analysis of rational use of electric energy and comparative characteristics are implemented on the university server.
