Abstract

The invention discloses an onboard navigation method based on digital speech transmission, which realizes information transmission between a Bluetooth module and a mobile phone having a Bluetooth function and a main control unit. The onboard navigation method is characterized in that the information transmission between the Bluetooth module and the mobile phone having the Bluetooth function and the main control unit is realized by the steps of transmitting a data carrier via a speech channel and then carrying out modulation and demodulation in background. The invention further discloses a terminal system of the onboard navigation method based on digital speech transmission, which comprises navigation equipment, a main control unit (MCU), the Bluetooth module, the mobile phone having the Bluetooth function and a processing background under communication with the mobile phone, wherein the MCU is in bidirectional connection with the navigation equipment via serial ports, the Bluetooth module is communicated with an audio channel of an A/D (Analog/Digital) converter of the MCU, and the processing background and the navigation equipment are further provided with audio modems. Accordingto the invention, a communication module is not needed on the basis of original functions of mobile phone, the cost is low and the unified standard can be easily implemented.

Description

A kind of vehicle mounted guidance method and terminal system based on the digital speech transmission
Technical field
The present invention relates to the vehicle mounted guidance technical field, more particularly relate to voice transmission method and system in the vehicle mounted guidance process.
Background technology
Generally having the Bluetooth function transfer of data in the onboard navigation system of prior art generally is to adopt data channel to carry out the transmission of relevant information, and different manufacturers all needs to be provided with the wireless module of oneself, adopt like this in transmission means, its poor compatibility each other of the product that different manufacturer releases, cause market comparatively chaotic like this, cost is higher simultaneously.How to address this problem, realize that the unification of product standard between the different vendor becomes present pressing for.
Summary of the invention
Purpose of the present invention be exactly provide for the deficiency that solves prior art a kind of can effectively realize unification, the cost of standard low based on voice transmission method and system in the vehicle mounted guidance process of digital speech transmission.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of vehicle mounted guidance method based on the digital speech transmission, it is to carry out message transmission between employing bluetooth module and the mobile phone of being with Bluetooth function and the master controller, it is characterized in that, the message transmission of carrying out between the mobile phone of described bluetooth module and band Bluetooth function and the master controller is by voice channel transmission data carrier, carries out modulation then on the backstage and gets final product.
The present invention also provides a kind of terminal system that realizes said method, comprise navigator, master controller MCU, bluetooth module, the band Bluetooth function mobile phone and with mobile phone carry out communication contact the processing backstage, described master controller MCU is connected by serial ports and navigator are two-way, it is characterized in that, described bluetooth module is communicated with the voice-grade channel of the A/D of master controller MCU, handle backstage and navigator and also be provided with the voice modulation decoder, digital information in the speech channel of bluetooth module transmission is separated, the digital signal decoding that maybe will handle backstage and navigator is an audio signal, is transferred to the mobile phone of band Bluetooth function.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: the present invention has adopted the audio speech passage to come transmitting data information, has utilized former client's cell-phone function, need not to increase in addition wireless module, and cost is low, simultaneously the unification of easier realization standard.
Description of drawings
Fig. 1 is a square frame principle schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the terminal system of the vehicle mounted guidance method based on digital speech transmission of the present invention, comprise navigator, master controller MCU and the band bluetooth module mobile phone and with mobile phone carry out communication contact the processing backstage, described master controller MCU is connected by serial ports and navigator are two-way, described bluetooth module is communicated with the voice-grade channel of the A/D of master controller MCU, handle backstage and navigator and also be provided with the voice modulation decoder, digital information in the speech channel of bluetooth module transmission is separated, the digital signal decoding that maybe will handle backstage and navigator is an audio signal, is transferred to the mobile phone of band bluetooth module.
The course of work of the present invention is such: the PTT button is set on navigator, behind the button, promptly connect and be connected to master controller MCU, be connected to the mobile phone of band band bluetooth module by the bluetooth module voice call, dial the backstage phone by mobile phone, demand information and processing backstage are linked up, handle the backstage and can carry out artificial treatment, the backstage is transferred to bluetooth module with needed data by mobile phone after putting information in order, be transferred to master controller MCU again by bluetooth module, by the voice modulation decoder, on navigator, demonstrate the needed information that can show.
