Abstract

The invention discloses a frequency-stabilized oscillatory type infrared positioning-based pattern recognizing and reminding system for signal lamps. The system comprises a power supply module, a reminding module, a central control module and a camera, wherein the reminding module, the central control module and the camera are connected with the power supply module. The reminding module and the camera are connected with the central control module. The central control module comprises a positioning module, a pattern recognizing module connected with the positioning module, and a speed sensing module connected with the pattern recognizing module. The system is characterized in that the positioning module is composed of a frequency-stabilized oscillation module, an infrared receiving circuit, a constant-current infrared transmitting circuit connected with the frequency-stabilized oscillation module, a single-chip microcomputer connected with the infrared receiving circuit, a distance threshold storage module and a triggering module, wherein the distance threshold storage module and the triggering module are connected with the single-chip microcomputer. The constant-current infrared transmitting circuit is controlled by the frequency-stabilized oscillation module. Therefore, infrared signals can be stably radiated by the constant-current infrared transmitting circuit, so that the stability of the system is improved.

Description

technical field [0001] The invention relates to a pattern recognition system, in particular to a pattern recognition and reminder system for signal lamps based on frequency-stabilized oscillation infrared positioning. 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...
