PURPOSE: A vehicle pass blocking system is provided to prevent the damage to a vehicle and a blocking bar even if a driver passes the blocking bar, since the blocking bar is installed to be rotatable by an axis bolt. CONSTITUTION: A vehicle pass blocking system comprises a sensor(11), a control unit, a motor(12), a frame(13), a blocking bar(14), a detector(16), a wired opening/closing unit and an interface unit(20). The control unit drives the motor with the sensor. The frame is coupled to the control unit and the rotating shaft of the motor to be coupled to the blocking bar. The frame and the blocking bar are rotatably coupled by the axis bolt. The frame is coupled to the detector. The detector detects the separation of the blocking bar. The control unit is connected to the detector, a buzzer(17), an LED and a wired opening/closing unit(30) forming an opening/closing switch. The interface unit is connected to a camera(21), a DVR(22) and a monitor(23).
