Embodiment

[0023] Such as figure 1 As shown, the signal lamp pattern recognition reminder system based on infrared ranging and positioning of the present invention is composed of a power supply module, a reminder module connected to the power supply module, a central control module and a camera; the reminder module and the camera are all connected to the central control module connected.

[0024] Wherein, the power module is used to provide working power for the reminder module, the central control module and the camera. The camera is used to collect video images in front of the car, and transmit the video images to the central control module. The reminding module is used for sending out corresponding prompting sounds according to the received reminding instructions or messages. The central control module is the control center of the whole system, which is composed of a positioning module, a pattern recognition module connected with the positioning module, and a speed perception module...

Abstract

The invention discloses an infrared distance measurement and positioning based mode identification reminding system for a signal lamp. The system comprises a power supply module, a reminding module connected with the power supply module, a central control module and a camera, wherein the reminding module and the camera are both connected with the central control module; the central control module consists of a positioning module, a mode identification module connected with the positioning module and a speed sensing module connected with the mode identification module; and the system is characterized in that the positioning module consists of a constant-current infrared transmission circuit, an infrared receiving module, a single-chip microcomputer connected with the infrared receiving circuit as well as a distance threshold storage module and a trigger module which are connected with the single-chip microcomputer. According to the system, the position of a vehicle is measured by adopting an infrared distance measurement technology, the measurement precision is high, the response is quick, and the phenomenon of false measurement or missing measurement does not occur.

Description

technical field [0001] The invention relates to a pattern recognition system, in particular to a pattern recognition reminder system for signal lamps based on infrared distance measurement and 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 of identify...
