Infrared obstacle-avoiding early-warning device

The utility model discloses an infrared obstacle-avoiding early-warning device which comprises a box cover and a base, wherein a steering engine, a sensor expansion board, a controller, a power supply and a buzzer are arranged on the base, the steering engine is connected with a pan-tilt, the pan-tilt is connected with infrared obstacle-avoiding sensors, and the controller is respectively connected with the steering engine, the infrared obstacle-avoiding sensors, the buzzer and the power supply through the sensor expansion board. According to the device, the infrared obstacle-avoiding sensors are used for detecting obstacles and sending detected information to the controller, distance obstacle warning is achieved by utilizing the controller to control working of the buzzer, and in order to expand the detection range, a structure in which the infrared obstacle-avoiding sensors are connected to the steering engine by the pan-tilt is adopted to enable the steering engine to drive an ultrasonic sensor to rotate,
