The invention provides an intelligent electronic safety rail used in places such as transformer stations, various engineering construction places and the like. An intelligent entrance guard control system and alarming rail control systems form an electronic safety rail and an electronic safety door. When the intelligent electronic safety rail is in use, working personnel record finger-prints or card numbers into the intelligent entrance guard control system first; no alarm signal is given out when the working personnel get in/out of the electronic safety door through the finger-prints or the card numbers; once that a person gets in the electronic safety door by force is detected, the intelligent entrance guard control system can give out a loud voice alarm to alert an operation superintendent that the person gets into the working area by mistake; and when that the person gets into a working area by mistake through the electronic safety rail is detected, a forbidden line built of raster is triggered, and a voice alarm is given out promptly. Through the adoption of the invention, a circle of invisible retaining wall is formed at the boundary of a guard area by utilizing the intelligent electronic safety rail, so that under normal conditions, when the working personnel get in/out of the guard area through the finger-prints or the card numbers, no alarm signal is given out; and once that the person gets into the guard area by force is detected, the loud voice alarm is given out. Therefore, the purpose of safety management is achieved; false alarms can be distinguished effectively; and the guard function is obvious.
