Abstract:

The main objective of the project is to detect rising water level in a river before the railway track at a reasonable distance from the rail track and intimate that to the nearest station master through GSM, to detain train movement. A programmable Microcontroller of 8051 family is interfaced with a water level sensor. Sensor will send an interrupt to the microcontroller indicating that it has crossed the danger point. So whenever there is an occurrence of such flood the  sensor sends a logic signal to the microcontroller that  is programmed in such a way that it will send an alert stored SMS through RS232 protocol to the SIM mounted GSM modem to the station master’s mobile number to detain train movement and to avoid accidents. The desired number is auto saved on the microcontroller over a missed  call. An LCD display is also made to indicate the status.

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier and it is then regulated to +5V using a voltage regulator 7805/7812 which is required for the operation of the microcontroller, GSM modem and other components
