In this study, attempt has been made to develop digital controller using a microcontroller to automate the bottling plant and to make it user-friendly for village entrepreneur of our country to increase the production of bottles filled with edible oils, country liquor alcohol, mustered oils, fruit juice, Jam, and Jelly, etc. In this era of rural industrialization, technological revolution/automation conventional plants with the manual bottle filling system are shrinking day by day due to high cost, low efficiency. As a result, the need for automated machinery is increasing in a very fast manner. To hold out the commitment of timely delivery of product and to meet the demand, hi-tech automated production even in rural areas has become essential. The grid interactive 1kW solar power supply as provided by the rural grid for 24x7days ensures the continuous production of this product. The field of automation has a notable impact in the rural society of our country. The design of the controller for automated bottling plant with limited capacity with 200 bottle capacity per shift in a day using microcontroller ATMEGA32, have been developed. The simulation study of functional and operational test on prototype unit has been performed, and the results have been found an encouraging one. The cost economy of prototype unit has been computed and analyzed, and the impact study has been carried out in rural society.

Supervisory control and data acquisition (SCADA) systems continuously monitor the real-time processes in the smart grid. The system software, which is based on a human-machine interface (HMI), makes intelligent decisions to assist the system operator and perform normal grid management activities. The management of SCADA networks and monitoring without proper security is a major concern, as many grids and plant networks still lack necessary monitoring and detection systems, making them vulnerable to attack. SCADA networks exploit physical weaknesses as well as cyber-attacks. Researchers have developed a monitoring system based on a field-programmable gate array (FPGA) and a microcontroller that allows for faster timing and system response. The cryptography-based substitution box (S-box) Advanced Encryption Standard (AES) and decryption method were proposed in the research paper, which may be merged with smart grid communication hardware and grid distribution as an integrated chip, synthesized on FPGA-Virtex-5 hardware. The method creates a platform for grid security by implementing a cryptographic-based security algorithm in hardware chips. The algorithm was designed using VHDL coding in Xilinx ISE 14.7 software and tested with various grid data sizes and key. The research represents a significant effort on the part of the businesses looking for solutions to secure the smart grid and plants by incorporating secure hardware.
