In this paper, a smart railway system is developed to monitor fine collection, food wastage and sales flow in railway pantry, passenger flow, security etc., various sensors are used to count the number of passengers who board the train in a coach. The sensors placed in the door can detect the person boarding the train. The ATmega328 controller used to check the data of passengers entering and exiting the train sends data constantly to every station through wireless module. The smart pantry uses the previous sales data of the food items and uses the data to predict the sales of products in future. The data acquired by the sensors is sent to cloud platform using ESP8266 node mcu and prediction of sales of products is done using the data. The passenger prediction uses the past data of number of passengers travelled in the train and uses the data to predict passenger flow in the trains based on seasonal changes and the data can be used to add the passenger coaches. The system can be adapted for railways because the proposed system is relatively cheap and the system can work efficiently and does not require much space. © Alpha Publishers. All rights reserved.

Analysis of passenger flow prediction model using machine learning algorithms for sustainable development in smart railway system

In this article, we study bistability, multiscroll, and symmetric properties of fractional-order chaotic system with cubic nonlinearity. The system is configured with hyperbolic function consisting of a parameter “ g.” By varying the parameter “ g,” the dynamical behavior of the system is investigated. Multistability and multiscroll are identified, which makes the system suitable for secure communication applications. When the system is treated as fractional order, for the same parameter values and initial conditions and when the fractional order is varied from 0.96 to 0.99, multiscroll property is obtained. Symmetric property is obtained for the order of 0.99. The fractional system holds only single scroll until 0.965 order and when the order increases to more than 0.99, it is having two-scroll attractor. This property opens a variety of applications for the systems, especially in secure communication. Adaptive synchronization of the system using sliding mode control scheme is presented. For implementing the fractional-order system in field-programmable gate array, Adomian decomposition method is used, and the register-transfer level schematic of the system is presented.

Fractional-order chaotic system with hyperbolic function

In this paper, we propose a family of circulant systems with conservative property. Various dynamical properties of the circulant systems are derived and investigated. Bifurcation plots are derived and presented for a system and the Lyapunov exponents are derived to show the existence of chaotic oscillations, and their sum being zero confirms the conservativeness for certain values of parameters. One of the proposed systems is then implemented in field programmable gate array (FPGA) to show the hardware reliability. We used the hardware–software co-simulation to see the phase portraits of the FPGA implemented system. The discrete integrators required for solving the initial value problem are implemented using the Euler’s method. The register transfer level schematics of the FPGA implemented system and the resources used for the implementations are presented. © 2019, Indian Academy of Sciences.

A family of conservative chaotic systems with cyclic symmetry

With the advent of Internet of Things (IoT), security breaches increases day by day which remain the major threat for an effective data communication. Nearly 14.4 million devices will be interconnected with each other by 2022, cyber-security threats will be the real challenge among the developers and researchers. In this paper, an effective framework for chaotic encryption based on 3D multi scroll hyperbolic functions are presented together with the dynamic quad tier architecture and electroencephalogram (EEG) signals. The dynamic characteristics of EEG signals and MAC parameters make the proposed system more suitable for the transmission of an effective data transmission. The test bed has been developed using Raspberry Pi 3-Cortex A-7 Quad Core architectures and the performance of the proposed architecture has been evaluated on the above test bed. Furthermore, experimental implementation and result analysis shows that the proposed architecture can provide more secure and high confidential data transmission. © BEIESP.

Chaotic encryption scheme using 3D multi scroll hyperbolic functions for IoT applications

This paper presents an assistance system for differentially abled people. It consists of Fuzzy logic control system and GpaD hand gesture technique to provide smooth and automatic control of the wheelchair in the presence of obstacles. The ultrasonic sensor is used for detecting obstacles. Actions in forward, reverse, right and left directions are taken care by GpaD which is based on IR sensor. Fuzzy logic controls the breaking power. The breaking power is based on the speed of the wheelchair and the distance between the wheelchair and an obstacle. The main purpose of this paper is to improve the safety of the differentially abled people and can be supervised from long distances without anybody’s help.

Gpad and Fuzzy Logic based Assistance System for Disabled People

Objective: The train collision avoidance system (TCAS) is a synergic approach for intervention of train in danger zone using Internet of things. Methods: The proposed system surveillance the signal condition and observe the disobedience of the track signal. A sensor is placed beneath the track, which senses the pressure, temperature, altitude of the track. The presence of train is observed by heavy pressure, change in temperature, and altitude on the track. Eventually, the system notifies the intervention of train being in danger zone using Internet of things by ThingSpeak IoT platform. An alarm is given to the train side that blow through Beaglebone black using Wi-fi module and if locomotive pilot does not respond, then the train stops by controlling braking system. Findings: Track signal plays a paramount role in cognizance of train’s direction. The disobedience of signal results in collision, derailment, and conflict. It is mainly occurred due to human error or rigid climate conditions like fog, rain and affects thousands of lives. TCAS-IoT prevails the problem of overshooting the track signal and acknowledging the locomotive pilot about intervention of train in danger zone. Conclusion/Improvement: The proposed TCAS-IoT can avoid train collision and capable of taking action before collision or derailment of trains. It is a unique way to synthesize the intervention of train in danger zone and can save lot of precious lives. © Springer Nature Singapore Pte Ltd. 2018.

Train Collision Avoidance System for Automatic Train Protection Using Internet of Things

Advancement in technologies to have a great vehicular experience safety system is very essential in automobiles. Accident can occur anywhere anytime hence there is a need to save human lives from an accident by detecting a mishap before it happens. As traffic hazards and road accidents are increasing day by day it causes huge loss of life and property because of the poor emergency facilities. The paper is aimed in advancements in cars for making it more interactive and intelligent for avoiding accidents on roads. As an improvement to safety systems a multi-sensor, control Area Network (CAN) based system is interfaced with Engine Control Unit (ECU) using ARM-7 microcontroller. In order to prevent from accidents different sensors are used to observe fatigue levels of driver, pulse rate, alcohol level, obstacle detection and also sudden collisions. Global positioning system, GSM and CAN technologies for faster communications make the system completely reliable, safe, and stable and it attains the expected result of real-time analysis of data very effectively to provide a safer drive.

Accident Avoidance System using CAN

Modbus is a common industrial field control bus protocol which is not only used in a wide variety of industrial applications like SCADA systems but also commonly used in building management systems(BMS) across the globe.Buildings generally use BTU,Water,Energy meters that operate on M-bus standard.M-bus devices cannot communicate directly with a Modbus based Building Management System(BMS).The network level incompatibility of a M-bus device to communicate with a Modbus master can be overcome by using a protocol conversion device having low conversion delay time and suitable voltage adjustment circuits.My project will focus on building a protocol conversion gateway for the M-bus slaves to communicate with a Modbus based master with minimum time delay using RS232 based serial medium for communication.
