Microcontroller based Railway Bridge Monitoring

Abstract

Railway Bridge monitoring in developing countries like India there is strong focus on national infrastructure. The maintenance of these bridges is many times overlooked. Furthermore, the present frameworks utilize muddled and surprising expense wired system and high upkeep optical fiber framework. Observing and investigating strength of scaffolds overwhelming hardware is critical for wellbeing, efficient, operational, making earlier defensive measures, and fix and support perspective. As of late there is developing interest for such bigger structures which thusly make individuals center more around security. By utilizing Microelectromechanical Systems (MEMS) Accelerometer we can perform Structural Health Monitoring by concentrate the dynamic reaction through proportion of surrounding vibrations and solid movement of such structures. Real-time location is tracked if the fault occurred.The Global Positioning System (GPS) is a satellite based route framework comprises of a system of 24 satellites situated into space. The framework gives basic data to military, common and business clients around the globe and which is unreservedly available to anybody with a GPS collector. GPS works in any climate conditions at anyplace on the planet. Ordinarily no membership expenses or framework charges to use GPS. A GPS beneficiary must be bolted on to the flag of in any event three satellites to evaluate 2D position (scope and longitude) and track development. With at least four satellites in sight, the recipient can decide the client's 3D position (scope, longitude and elevation). Once the vehicle position has been resolved, the GPS unit can decide other data like, speed, separation to goal, time and other. GPS collector is utilized for this examination work to identify the vehicle area and give data to mindful individual through GSM innovation. D. Temperature SensorThe DS18B20 Digital measuring device provides nine to 12-bit (configurable) temperature readings that indicate the temperature of the device. The DS18B20 communicates over a 1-Wire bus that by definition needs only 1 information line (and ground) for communication with a central microchip. In addition, the DS18B20 will derive power directly from the data line ("parasite power"), eliminating the need for an external power supply. This sensor has been included in many applications such as Thermostatic Controls, Industrial Systems, consumer Products, Thermometers, Thermally Sensitive Systems.Power provide vary is three.0V to 5.5V Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F±0.5°C accuracy from -10°C to +85°C Converts 12-bit temperature to digital word in 750 ms (max.)Can be steam-powered from knowledge line Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition) V. CONCLUSIONThe Railway Bridge monitoring system using microcontroller and its sensor module which makes the system easy to monitor the fault. The system easily detects the position of a fault. ...
