Detailed Description
the invention provides a vehicle-mounted wireless interaction method based on DTMF and a system thereof, which utilize the prior DTMF (Dual Tone Multi Frequency) technology, directly utilize a loudspeaker of a control device to send signals, and a microphone of a vehicle-mounted device to receive the signals, thereby realizing wireless instruction interaction. And other wireless communication hardware equipment does not need to be carried, so that the product cost is saved, and the interaction reliability is high. In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 in conjunction with the block diagram shown in fig. 2, the DTMF-based vehicle-mounted wireless interaction method includes the following steps:
S100, the control equipment acquires a control instruction, performs DTMF coding, and converts the control instruction into a corresponding audio signal to be transmitted;
s200, the vehicle-mounted equipment receives the audio signal, performs DTMF analysis and restores the audio signal into a corresponding control instruction;
And S300, analyzing and processing the control instruction by the vehicle-mounted equipment, and executing corresponding control.
In this embodiment, the control device may be a portable mobile terminal provided with a speaker, such as a mobile phone and a tablet computer. The control device downloads and installs the DTMF interactive application from the network, and correspondingly loads DTMF coding software (correspondingly, a DTMF coding module). When the DTMF interactive application is opened, namely a DTMF interactive mode is started, an input module of the control equipment pops up a control input window so that a user can input control information. The control information may be text control information or voice control information. The control information includes direct command information and event reservation information. The command format of the direct command information is typically: actions + objects, such as "navigate to location a" and "increase volume by two bins". The command format of the event reservation information then increases the reservation time: reserved time + action + item, such as "turn on air conditioner after 5 minutes". The user can input the control information in a text or voice mode. In the implementation, the command format of the control information may also have other ways, and the DTMF coding module can extract the main content (i.e. the command format) to facilitate the user input.
before the step S100, the control device generates a control command (digital signal) that can be recognized by the corresponding mobile terminal according to the control information (text or voice) input through the control input window. In step S100, the DTMF coding module performs DTMF coding on the control instruction by using the existing DTMF technology to obtain an audio signal, so as to implement a process of converting the control instruction into a corresponding high-low frequency audio signal, and finally, the audio signal is played (i.e., transmitted) through a speaker of the vehicle-mounted device.
In step S200, the audio signal is received by a microphone of the in-vehicle device. Since the audio signals of high and low frequencies have no directional limitation, they can be received by the microphone as long as they are in the vehicle. The main machine of the vehicle-mounted equipment is correspondingly provided with a DTMF analysis module, the microphone transmits the audio signals to the DTMF analysis module for DTMF analysis, and the audio signals are restored into corresponding control instructions and transmitted to the main control chip on the main machine.
It should be understood that the control information is information that can be identified by the user, and the control command is data that can be identified by the system converted according to the control information, and the format of the control command is different from that of the control information, but the control command is carried by the control command in the same format. Therefore, in step S300, the main control chip on the host of the vehicle-mounted device analyzes the control command, and can recognize the control operation carried by the control command, that is, what control needs to be performed. The main control chip controls the corresponding module component on the vehicle-mounted equipment to execute the control instruction, so that corresponding control is realized.
For example, if the control instruction is "navigate to a location a", the main control chip starts the navigation module according to the "navigation" instruction, transmits the location a to the navigation module as a destination, and the navigation module plans a navigation line according to the location a and the current position of the user and transmits the navigation line and a map to the display screen for display.
if the control instruction is that the air conditioner is turned on after 5 minutes, the main control chip starts the timer according to the time after 5 minutes, and after the time reaches 5 minutes, the main control chip outputs a turn-on signal to the control module of the air conditioner according to the time when the air conditioner is turned on, so that the air conditioner is automatically turned on.
based on the above embodiment, the present invention further provides a vehicle-mounted wireless interactive system based on DTMF, as shown in fig. 2, including a control device 10 and a vehicle-mounted device 20. The control device 10 obtains the control command and performs DTMF coding, and converts the control command into a corresponding audio signal for transmission. The vehicle-mounted equipment 20 receives the audio signal, performs DTMF analysis and restores the audio signal into a corresponding control instruction; and the vehicle-mounted equipment analyzes and processes the control command and executes corresponding control.
wherein, the control device 10 may be a mobile terminal such as a mobile phone, a tablet computer, etc., and includes:
an input module 110, configured to pop up a control input window when a DTMF interaction mode is started; generating a corresponding control instruction according to the control information input by the control input window;
The DTMF coding module 120 is configured to convert the control instruction into a corresponding high-low frequency audio signal, and transmit the audio signal to a speaker of the vehicle-mounted device;
a speaker 130 for playing the audio signal.
The in-vehicle apparatus 20 includes:
A microphone 210 for receiving the audio signal;
A DTMF parsing module 220, configured to perform DTMF parsing on the audio signal, and restore the audio signal to a corresponding control instruction;
The main control chip 230 is configured to analyze the control instruction and identify a control operation carried by the control instruction; and controlling the corresponding module component to execute the control instruction.
In summary, the vehicle-mounted wireless interaction method and the system thereof based on DTMF provided by the present invention generate the corresponding control instruction according to the control information input by the user, convert the control instruction into the corresponding high-low audio signal by using DTMF coding, and send the signal through the speaker to be received by the microphone of the vehicle-mounted device; and the vehicle-mounted equipment performs DTMF analysis on the audio signal, restores the audio signal into a corresponding control instruction and gives the control instruction to other module parts in the vehicle-mounted equipment to execute the instruction. On the basis of no need of a hardware communication module, the existing microphone and loudspeaker are used as an equipment communication transceiver, and the DTMF software coding and decoding technology is used for realizing wireless transmission of control instructions, so that interaction between an owner and vehicle-mounted equipment is realized, and hardware cost is saved. Meanwhile, in the vehicle-mounted equipment without the communication module, a DTMF analysis module (namely a DTMF audio analysis software component) can be added by software upgrading without replacing a hardware platform.
