The invention discloses a voice reminding device for green light switching of a signal lamp, which is arranged in a vehicle. The voice reminding device comprises a GPS (Global Positioning System) signal receiving module and an STM32 single-chip microcomputer wherein the GPS signal receiving module obtains the vehicle positioning information in real time and sends the vehicle positioning information to a database storage module for storage, the STM32 single-chip microcomputer is connected with a road traffic network through a communication module, obtains road network data and signal timing data, and stores the road network data and the signal timing data in the database storage module, the STM32 single-chip microcomputer analyzes and obtains a lane where the vehicle is located at the current moment according to the positioning information and the road network data, and analyzes and obtains the green light switching remaining time of the lane where the vehicle is located according to the signal timing data; when the vehicle encounters the red light and is parked, the STM32 single-chip microcomputer controls the voice reminding module to conduct voice reminding when the green light switching remaining time of the lane where the STM32 single-chip microcomputer is located reaches a preset value. The system can remind a vehicle owner that the red light in the driving direction is about to turn into the green light in advance according to the road traffic light condition, can reduce the delay loss time, and improves vehicle passing efficiency.

    本发明公开的一种信号灯绿灯切换的语音提醒装置,安装在车辆内,包括:GPS信号接收模块实时获取车辆的定位信息,并发送给数据库存储模块进行存储;STM32单片机通过通讯模块连接道路交通网络,获取道路网络数据和信号配时数据,并存储至数据库存储模块;STM32单片机根据定位信息和道路网络数据,分析得到车辆当前时刻所在车道,在结合信号配时数据分析得到所在车道的绿灯切换剩余时间;当车辆遭遇红灯而停车时,STM32单片机控制语音提醒模块在所在车道的绿灯切换剩余时间达到预设值时进行语音提醒。本发明可以根据道路红绿灯情况提前提醒车主所驾驶方向的红灯即将变成绿灯,可以减少延误损失的时间,提高汽车通行效率。
