The people entering a theme park are provided with a small unit called as RF receiver which contains an emergency button. Whenever the person enters a ride or a game in the theme park, they will be intimated with their location in an LCD receiver, this is done by an RF transmitter kept in various location with fixed IR sensors, which senses the person and the signal is transmitted to the receiver. In the receiver, a programmed Arduino decides the location based on the received information and it is displayed in the LCD display. When there is an emergency they can push a button present on the receiver unit and the information goes to security as well as controller of the game in the form of an alert message along with the location of the person using GSM module. Here the location of the person is found using GPS tracker.
