The research relevance is determined by the need to reduce the energy intensity of intensive livestock production. The latter is possible on the basis of innovative methods and technical means of intelligent management of complex biotechnical systems with identification of animal behaviour and control using video surveillance systems. The paper presents the results of experimental researches of the energy efficiency of an automated infrared irradiation system for weaners with irradiation modes set according to analysis of video surveillance of animal behaviour. A sign for the location of animals along the floor area relative to a warm source – a dark infrared irradiator, was defined as an ethological sign for the analysis of animal behaviour. As a result of experimental studies, based on the video surveillance data, IR-irradiation modes were determined by statistical analysis of the ethological sign of the location of animals relative to the thermal source of IR-irradiation. These modes were recorded in the program of the microcontroller, within 20 days the experimental group of animals was exposed to IR-irradiation according to the established modes. It was determined that the developed irradiation modes ensure additional profit of 2.97 roubles per animal, including economic effect for heating of 0.89 roubles per animal. The developed IR irradiation modes for weaners exclude general heating requirement. The IKOV-1 automated plant allows to develop energy-efficient zoology hygienic modes for animals management based on data processing and video surveillance equipment using air temperature sensor in the IR irradiation area.

Object recognition in video surveillance systems is the primary and most significant challenge task in the field of image processing. Video Surveillance systems provides us continuous monitoring of the objects for the enhancement of security and control. This paper presents novel approach recognizing the objects using Shi-Tomasi approach for detecting the corners of the object and then applies the Lucas-Kanade techniques to extract the features of the objects. The main objective of this paper is providing precise recognition of objects and estimation of their location from an unknown scene. Whenever the object is recognized from extracted frames of the input video the background subtraction will be applied. Then the classification of the objects into their respective categories can be achieved using support vector machine classifier by supervised learning. In case of multiple objects of different classes in a single frame, a vector containing the classes of all the detected in that frame is produced as output. The results of this work are drawn in the MATLAB tool by considering the input video dataset taken from various sources and extracting the frames from the input video for the detection then the efficiency of the proposed techniques will be measured.

The article substantiates the relevance of processing thermolabile materials into dried foods, as one of the alternative options for fresh fruits and vegetables. It is noted that drying, as a method of conservation, is characterized by high energy intensity and increased requirements for the quality and safety of the final product. The naturalness of the dried products and the environmental cleanliness of the process come to the fore. The criteria of quality and efficiency of the process are combined into a single task: increasing the efficiency of the drying process and creating energy-efficient equipment. The analysis of heat and mass transfer during convective drying allowed us to establish methods and ways to improve the energy efficiency of the process. Based on a synthesis of theoretical and experimental studies, the optimal heat and humidity parameters of dehydration were determined, according to which the temperature of the material during drying does not exceed the maximum permissible value. This contributes to the preservation of valuable nutrients in the final product. Prevention of excess material temperature above the acceptable level is confirmed by the nature of the change in the numerical value of the Rebinder effect and is provided by drying in multi-stage dehydration modes, including high-temperature high-moisture method using zone drying installations of tunnel and belt type, as well as heat-pump drying installations with low heat consumption. It was emphasized that the drying of thermolabile materials is carried out in an environment of pure hot air without the use of inert and chemically synthesized substances. Non-contact air heating is carried out using traditional fuels as well as secondary and renewable energy sources. It is noted that the design features of the drying equipment make it possible to distribute the intensity of the thermal effect on the material, depending on its moisture content into zones, and also automatically maintain and control these parameters for a specific type of raw material. The adopted recirculation system of the drying agent helps prevent emissions of waste coolant and reduces thermal pollution of the environment.

Key Update

In the construction process of smart cities, more and more video surveillance systems have been deployed for traffic, office buildings, shopping malls, and families. Thus, the security of video surveillance systems has attracted more attention. At present, many researchers focus on how to select the region of interest (RoI) accurately and then realize privacy protection in videos by selective encryption. However, relatively few researchers focus on building a security framework by analyzing the security of a video surveillance system from the system and data life cycle. By analyzing the surveillance video protection and the attack surface of a video surveillance system in a smart city, we constructed a secure surveillance framework in this manuscript. In the secure framework, a secure video surveillance model is proposed, and a secure authentication protocol that can resist man-in-the-middle attacks (MITM) and replay attacks is implemented. For the management of the video encryption key, we introduced the Chinese remainder theorem (CRT) on the basis of group key management to provide an efficient and secure key update. In addition, we built a decryption suite based on transparent encryption to ensure the security of the decryption environment. The security analysis proved that our system can guarantee the forward and backward security of the key update. In the experiment environment, the average decryption speed of our system can reach 91.47 Mb/s, which can meet the real-time requirement of practical applications.

To overcome the difficulties of extending the main power grid to isolated locations, this paper proposes the local installation of a combination of three renewable energy sources, namely, a wind driven DFIG, a solar PV unit, a biogas driven squirrel-cage induction generator (SCIG), and an energy storage battery system. In this configuration one bi-directional SPWM inverter at the rotor side of the DFIG controls the voltage and frequency, to maintain them constant on its stator side, which feeds the load. The PV-battery also supplies the load, through another inverter and a hysteresis controller. Appropriately adding a capacitor bank and a DSTATCOM has also been considered, to share the reactive power requirement of the system. Performance of various modes of operation of this coordinated scheme has been studied through simulation. All the results and relevant waveforms are presented and discussed to validate the successful working of the proposed system.

AbstractLithium-ion battery energy storage systems (Li-ion BESS), due to their capability in providing both active and reactive power services, act as a bridging technology for efficient implementation of active network management (ANM) schemes for land-based grid applications. Due to higher integration of intermittent renewable energy sources in the distribution system, transient instability may induce power quality issues, mainly in terms of voltage fluctuations. In such situations, ANM schemes in the power network are a possible solution to maintain operation limits defined by grid codes. However, to implement ANM schemes effectively, integration and control of highly flexible Li-ion BESS play an important role, considering their performance characteristics and economics. Hence, in this paper, an energy management system (EMS) has been developed for implementing the ANM scheme, particularly focusing on the integration design of Li-ion BESS and the controllers managing them. Developed ANM scheme has been utilized to mitigate MV network issues (i.e. voltage stability and adherence to reactive power window). The efficiency of Li-ion BESS integration methodology, performance of the EMS controllers to implement ANM scheme and the effect of such ANM schemes on integration of Li-ion BESS, i.e. control of its grid-side converter (considering operation states and characteristics of the Li-ion BESS) and their coordination with the grid side controllers have been validated by means of simulation studies in the Sundom smart grid network, Vaasa, Finland.
