RF BASED RAILWAY BRIDGE DAMAGE NOTIFICATION WITH ALERT
Abstract:
The Safety Risk Model (SRM) is RF Based representation of risk on Rail track controlled infrastructure (RCI). It provides a structured representation of the causes and consequences of potential accidents arising from railway operations and maintenance the over bridge for river.
In railway bridges, any time the bridge its striking due to weather condition, floods, earthquake, cyclone, etc. Now days system have some limitations, if the bridge or track damaged, that information goes to railway authority people, they notifies and informs to the corresponding trains it will takes more time informing those information. So to avoid delays, our proposed system will immediately notifies and informs the current train comes on the track through wireless medium.
Bridge damage status is monitored by the sensor and wireless modules, when the sensor not getting signal, immediately nearby wireless system notifies and alert or informs to the current train on the track. The above task can achieve through microcontrollers, RF modules, sensors.
Microcontroller
In our project we are using the AT89S51 micro-controller. The AT89S51 provides the following standard features: 4K bytes of Flash memory, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, five vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the AT89S51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.
