SENSOR NODE, SAFETY SYSTEM OF CROSSROAD AND CONTROLLING METHOD THEREOF

摘要

The present invention relates to a sensor node, an intersection safety system, and a control method of the intersection safety system. According to the present invention, the intersection safety system detects a vehicle entering an intersection using a sensor node including a pair of geomagnetic sensors, and controls a road marker corresponding to the direction of the detected vehicle entering the intersection among road markers arranged in the intersection to emit a light emitting signal indicating a hazardous situation when the vehicle entering the intersection is detected.
