Voice information push method, vehicle-mounted unit and electronic non-stop charging system

Abstract

The invention relates to a voice message pushing method, an on board unit, and an electronic toll collection system. The electronic toll collection system comprises the on board unit (OBU), a road side unit (RSU), and an information service platform server, the on board unit (OBU) comprises a micro-controller MCU module, a speech driving circuit module, and a loudspeaker electrically connected with the speech driving circuit module, and the micro-controller MCU module controls the speech driving circuit module to convert information received by a radio frequency transmission and reception module to audio signals so that the audio signals are recovered to voice for playing through the loudspeaker. According to the method, the on board unit, and the electronic toll collection system, through the road side unit (RSU), data communication is accomplished, the vehicle position and the driving direction are located, reliable guarantee is provided for information screening, useless information is effectively blocked, information is provided for each vehicle equipped with the on board unit (OBU) in a targeted manner, and vehicle drivers can drive in an attentive manner and select the fastest path to arrive at the destination.

Description

technical field [0001] The present invention relates to an information broadcasting method and a device and a system for realizing the method, in particular to a broadcasting method for selectively playing information according to specific needs and a device and a system for realizing the method. Background technique [0002] Most of the vehicle drivers understand the road traffic conditions in a driving area through the traffic broadcast channel received by prior art radios, so as to avoid congestion and arrive at the destination as soon as possible to select an appropriate path. But the prior art traffic broadcasting channel can only generally provide the road traffic situation in the whole driving area. The driver of the vehicle only cares about the traffic conditions of the roads that will pass through the path ahead, and does not care about the traffic conditions of the roads that will not pass through the paths or areas. The driver of the vehicle needs to filter the r...

AI Technical Summary

Problems solved by technology

This solution can solve the problem of providing road traffic conditions to vehicle drivers in a timely manner, but it still cannot screen the listening information, and there is still the problem of useless information dissemination

Moreover, configuring a radio dedicated to receiving the subcarrier signal increases the cost of use by the driver of the vehicle

[0004] The Digital Audio Broadcasting system using the DAB system for short, combined with the Global Positioning System, can provide broadcast information according to the vehicle's driving position, but this solution requires the full support of broadcast stations and vehicle terminal manufacturers, which is costly and popular. Difficult, less likely to be commercially available

[0005] There is also a solution that uses mobile communication terminals commonly called mobile phones to complete the push of road traffic information, but the mobile communication terminal supports functions that are too open. This solution inevitably uses personal location positioning information, which involves personal privacy, and is difficult to be used by mobile communication terminal users. accept

Moreover, the power of the mobile communication terminal is not enough to support long-term use with the vehicle, and it is difficult to popularize it by keeping it online for a long time

[0006] Therefore, there is no broadcast information push scheme that can shield useless information for the destination of the vehicle in the prior art
