The invention discloses a sharp turn lane anti-collision early warning method and system. The method comprises the following steps: S1, collecting a vehicle infrared image to train a YOLOv5 vehicle detection model and deploying the vehicle detection model in a microcomputer; s2, detecting a vehicle target, if not, entering the step 3, and if yes, entering the step 4; s3, if the early warning command is not issued, the early warning device does not work; s4, judging whether vehicles pass through the two sides of the sharp turn lane or not, if only one side is provided with a vehicle, entering the step 5, and if both sides are provided with vehicles, entering the step 6; s5, a command is given to the early warning device on one side where the vehicle passes, the signal lamp flickers, and the voice broadcast device gives out early warning, so that the turning safety of the vehicle is improved; and S6, the microcomputer issues early warning commands to early warning devices on the two sides of the curve at the same time, signal lamps on the two sides flicker, voice broadcast devices on the two sides give out early warning, and collision accidents of the vehicles on the two sides are avoided. The system can detect a plurality of targets at the same time, has the advantages of being large in information amount and rapid in early warning, enables a driver to make a response as early as possible, and avoids collision accidents.

    本发明公开了一种急转弯道防碰撞预警方法和系统,其中方法包括以下步骤:S1,采集车辆红外图像训练YOLOv5车辆检测模型并部署于微型计算机;S2,检测车辆目标,若无进入步骤3,若有进入步骤4;S3,不下达预警命令,预警装置不工作;S4,判断急转弯道两侧是否均有车辆通行,若只一侧有车辆,进入步骤5,若两侧均有车辆,进入步骤6;S5,对车辆通行的一侧预警装置下达命令,信号灯闪烁,语音播报装置发出预警,提高车辆过弯安全性;S6,微型计算机对弯道两侧预警装置同时下达预警命令,两侧信号灯闪烁,两侧语音播报装置发出预警,避免两侧车辆发生碰撞事故。本发明可以同时检测多个目标,具有信息量大、预警迅速的特点,让驾驶员尽早做出反应,避免碰撞事故的发生。
