FPGA application for wireless monitoring in power plant

The process of automation and monitoring in industrial control system involves the use of many types of sensors. A programmable logic controller plays an important role in the automation of the different processes in the power plant system. The major control units are boiler for temperature and pressure, turbine for speed of motor, generator for voltage, conveyer belt for fuel. The power plant units are controlled using microcontrollers and PLCs, but FPGA can be the feasible solution. The paper focused on the design and simulation of hardware chip to monitor boiler, turbine, generator and conveyer belt. The hardware chip of the plant is designed in Xilinx Vivado Simulator 17.4 software using VHDL programming. The methodology includes VHDL code design, simulation, verification and testing on Virtex-5 FPGA hardware. The system has four independent buzzers used to indicate the status of the boiler, generator, turbine motor and conveyer belt in on/off conditions respectively. The GSM is used to display corresponding message on the mobile to know the status of the device in on/off condition. The system is very much helpful for the industries working on plant automation with FPGA hardware integration.

Indiscriminate collection of Arnebia benthamii roots from wild for extraction of red pigments by traders prompted to put this Himalayan plant species under critically endangered category. Concerning the development of sustainable phytoconstituents sources, the present study is aimed at understanding the factors crucial for the scalability of A. benthamii cell suspension cultures. Here, the effect of orbital shaking speed (60–80 rpm) and inoculum density (5–15%) on leaf-induced cell suspension cultures during sequential scale up in shake flask (0.25–5 L) was assessed. The suspension cultures were established on Murashige and Skoog medium supplemented with 10 μM 6-benzylaminopurine and 5 μM indole-3-butyric acid having a 20-days cultivation cycle. The data revealed a significantly (p ≤ 0.05) high biomass productivity (523.80 ± 5.95 g/L, fresh weight) in 0.25 L vessel with 10% inoculum at 70 rpm as compared to large (5.0 L) volume flask (310.80 ± 32.85 g/L). Interestingly, the optimum inoculum density was found to vary with the size of culture vessels. Furthermore, noticeable effects of sequential scaleup with shaking speed and inoculum density were also observed on hydrogen peroxide (stress indicator) production as well as enzymatic (catalase and phenylalanine ammonia-lyase activity) and non-enzymatic (phenolic compounds) antioxidant potential. A. benthamii cells cultivated with optimized conditions had a significant amount of red pigment, with 669.17 ± 26.71 mg dry weight/L yield of total shikonin derivatives. In conclusion, the results clearly demonstrated the likelihood of scalability using optimized process variables for the production of natural red pigments using A. benthamii cell suspension cultures.
