Abstract

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.

Description

technical field [0001] The invention relates to a pattern recognition system, in particular to a pattern recognition and reminding system for an infrared positioning signal lamp based on a shaping circuit. Background technique [0002] At present, with the continuous development of the economy, the number of cars has increased sharply, and urban roads are becoming increasingly congested. In order to ensure traffic order and pedestrian safety, there are generally a group of red, yellow, and green traffic lights on each road. Through the state conversion of the signal lights, command All kinds of vehicles and pedestrians pass safely and realize the automation of traffic management. [0003] In order to prevent running a red light by mistake, at present, a vehicle-mounted signal light prompt system is used or a signal transmitting device is installed in a signal light control system, and a signal receiving device is installed in the car, so as to achieve the purpose of identify...
