The invention discloses a shaping-circuit-based mode identification prompting system for an infrared positioning signal lamp. The system is composed of a power supply module, a prompting module connected with the power supply module, a central control module, and a camera. The prompting module and the camera are connected with the central control module; and the central control module includes a positioning module, a mode identification module connected with the positioning module, and a speed sensing module connected with the mode identification module. The system is characterized in that the positioning module consists of a constant-current infrared transmitting circuit, an infrared receiving circuit, a shaping circuit connected with the infrared receiving circuit, a single-chip microcomputer connected with the shaping circuit, and a distance threshold storage module and a trigger module, wherein the distance threshold storage module and the trigger module are connected with the single-chip microcomputer. According to the invention, the shaping circuit carries out processing on an infrared signal reflected by a vehicle, so that a distortion phenomenon of the infrared signal during the transmission process can be reduced. Therefore, precision of vehicle position determination can be enhanced.
