IOT based Railway Crossing Gate Status detection and Security Code Generation System based on ESP8266

In rapidly developing nations like India, the railway system plays a pivotal role in facilitating transportation for the population. However, the safety of level crossing gates within this extensive railway network is of utmost importance and requires careful consideration. Unfortunately, due to human oversight, a significant number of accidents occur daily at these junctures, prompting a pressing need for technological interventions to address this issue. This study delves into two key approaches: firstly, the automation of railway gate operations at level crossings to streamline closure processes and reduce human involvement. A practical demonstration of this concept is showcased through a scaled-down model, which effectively tackles the challenge at hand. In this model, strategically positioned sensors near the level crossing gates detect approaching trains at a predetermined distance from the railway track. Subsequently, these proximity sensors relay signal pulses to a controller situated at the level crossing site, triggering motor activation for automated gate closure and opening. Secondly, the focus shifts towards monitoring the status of the crossing gates. Instances occur where gatekeepers unintentionally overlook gate closure and fail to communicate the security code to the station master, potentially leading to accidents. To address this issue, a system is proposed to generate the security code upon detecting the status of the railway gate, utilizing microcontrollers, LCD displays, and proximity sensors.
