This paper deals with the upgradation of CNC machine and its flexibility for modern technologies. In this paper, designing of control panel and its implementation is discussed. Different components are mounted in control panel to protect the system in case of power failure and protect motors against phase down. Almost all the industries use PLCs now-a-days because it is highly compatible, reduces wiring, and makes the design more compact and reliable. This is as up-gradation of CNC machine. Generally, PLCs are programmed in “ladder logic”, which strongly resembles a schematic diagram of relay logic. Different ladder logics are developed for performing different operations. This article can be extended further by emerging it with IIoT, i.e. Industrial Internet of Things, where we can monitor CNC machines from remote place.
In the present time, the multi-phase Permanent Magnet Synchronous Machines (PMSMs) are being popular in the industries with efficient performance. In future, the multi-phase Permanent Magnet (PM) synchronous machines may be used in the variable speed drive applications, especially in renewable energy generation. Therefore, an accurate simulation model is needed for variable speed applications of PMSMs. Therefore, in this paper, an attempt has been made to make variable speed PMSMs simulation models in the latest MATLAB/Simulation environment with effective performance. The three phase and five phase variable speed PMSM machines models have been developed and both the performances have been compared. For performance comparison, three motor parameters have been used; these are stator currents, rotor speed, and electromagnetic torque. In the simulation models, two control loops have been used for efficient performance of the motor. The inner loop is used to control the speed of the motor and outer loop is used to control stator currents. The PI controller has also been used for motor controlling purpose. Finally, the authors state that the five phase variable speed PMSM motor model gives encouraging results as compared to three phase PMSM motor.
The MST radar is situated at National Atmospheric Research Laboratory (NARL), Gadanki, Andhra Pradesh. This radar is used to investigate the atmospheric dynamics in the regions of Mesosphere, Stratosphere, and Troposphere (MST). MST radar was developed with an active phased antenna array consisting of 1024 Yagi-Uda antenna elements and operated by a frequency of 53 MHz. In this article, the authors introduce new hybrid window functions by using a combination of Kaiser and Blackman windows. The new hybrid window functions exhibit low side lobe levels and narrow beam width of main lobe so that the spectral leakage is minimum. The proposed window based algorithms has been applied to MST radar time series data to compute Doppler power spectrum. After computing Doppler spectrum, the wind parameters like Zonal U, Meridional V, and Wind velocity W can be calculated from the Doppler profile. The obtained wind velocity components of the MST radar data is validated through the Global Positioning System (GPS) Radiosonde data.
Paralyzed people find it difficult to communicate their intent to serve outside world. Hence, this work provides a Mind Controlled communication system that uses Brain Computer Interface which can bypass different communication channels like neurons’ electrical activity, muscles, and thoughts to supply direct communication and management between the physical devices and human brain by translating dissimilar patterns of brain activity into instructions followed by the conversion of predefined text on the screen into voice. The proposed system consists of: Amplifier Filter circuits and LabVIEW software for signal processing and acquisition. The main aim of this work is to develop a brain computer interface system called BCI system that allows the paralyzed people to communicate their intention without any difficulty, provided it is more superior which may assist disabled folks in their everyday life. Different messages are put up on the visual stimulation screen and made to flicker at different frequencies. When patient looks at one of the flickering frequency on the screen, the same frequency is generated in the visual cortex of the human brain and the frequency is then determined by signal acquisition system and translates the predefined assigned message to voice.
4G mobile phones are able to perform video coding and streaming over wireless networks, but are often constrained by the energy supply and end-to-end delay requirements. Video transmission via wireless channels with good Quality of Service (QoS) is still strenuous problem as it is a difficult task to deliver video content through limited bandwidth and error prone networks. In a real time wireless video communication system, the capture-to-display delay would significantly affect the overall video reception quality. To study, control, and optimize the quality of service parameters in the recent video transmission schemes, the DRDO for the wireless video communication system is extented and a novel control algorithm is proposed by investigating the allocation of capture-to-display delay to different delay components. Causes of end-to-end delay are identified and quantified, where the average end-to-end distortion under the transmission rate and end-to-end delay are considered by a joint selection of both source coding and channel coding parameters. To guarantee the Quality of Service (QoS), different service levels are specified for various stream of traffic in terms of delay, distortion, power, throughput, rate, and packet loss. This survey highlights, the tradeoff between various QoS parameters in the area of wireless video communication systems and quality of the reproduced picture.
The improvement of knowledge and substructure takes through our inhales natural. The arrival of equipment consumes improved the road traffic exposures and the road accident take place regularly which practicalities enormous injury of lifetime and belongings because of the concentrated emergency facilities. Our development resolve deliver an right justification to this problem. An accelerometer can be recycled popular a car apprehension submission so that hazardous motivating can be searched. It container be rummage-sale as a crash or rollover detector of the vehicle over and subsequent an accident, an accidents can be recognized with a help of an accerlometer sensor. The main aim of implemented this project identification of accidents through vibrations the sensor is notice the signals of vehicle moves, the MEMS sensor is pass the signal to the ARM controller to performed action. The signal is send to the GSM module it gives accident location of information to the rescue team or pre-defined numbers after receiving the message rescue or predefined numbers know the accident location. Then takes the immediate action.
