Intelligent Safety Navigation System

Abstract

An intelligent safety navigation system includes a plurality of transmitting devices respectively installed on a plurality of traffic signs, and a satellite navigation device installed on a vehicle. Each transmitting device includes a transmitting unit that is electrically connected to the corresponding traffic sign and transmits its travel information. The satellite navigation device includes a receiving unit that receives satellite signals and the driving information, and a navigation unit that integrates the aforementioned signals and information to generate a navigation message, the navigation message including the first traffic sign to pass on the driving path. driving information. Because the sending unit is electrically connected to the traffic signal and transmits its driving information, the driver can know the state of the traffic signal in advance, so that the driver can respond in advance to improve driving safety, and also reduce unnecessary acceleration actions to achieve energy saving. carbon reduction effect.

Description

technical field [0001] The invention relates to a navigation system, in particular to an intelligent safety navigation system. Background technique [0002] With the technology of satellite navigation becoming more and more mature and the manufacturing cost getting lower and lower, the satellite navigation device has become one of the necessary electronic devices for car drivers. The satellite navigation device estimates the latitude and longitude information of the car by receiving at least four satellite signals, and compares the latitude and longitude information with the built-in electronic map to obtain the location information of the device. Then, the satellite navigation device executes the route planning function and the navigation function to assist the driver to drive to the desired destination. [0003] However, although the existing satellite navigation device can see that there is a crossing in front of the driving path, it cannot know what the state of the tra...

AI Technical Summary

Problems solved by technology

[0003] However, although the existing satellite navigation device can see that there is a crossing ahead from the driving path, it cannot know the state of the traffic signal at the crossing in advance and the driver cannot make preparations in advance.

In addition, the position of the traffic signal on the driving route is displayed through the built-in electronic map, but if the position of the traffic signal changes due to road redesignation, or the satellite navigation device does not provide new electronic maps regularly, will affect the correctness of the navigation route
