Sub- musical instrument 91 and above-mentioned intelligent terminal 92.
It should be noted that intelligent terminal involved in the present invention include being not limited to smart mobile phone, tablet computer,
PDA and other terminal devices with data processing function.In general, intelligent terminal refers to there is independent operating system, it can
Voluntarily to install the program of the third party service providers such as software, game offer by user, constantly set by this class method to hand-held
Standby function is expanded, and such terminal equipment 1 of wireless network access can be realized by mobile communication network.
Carry out the application process of wireless data communication system that the present invention is further explained below by specific embodiment.Such as figure
Shown in 10, electronic musical instrument uses smart mobile phone using drum machine, intelligent terminal.Drum machine coordinates smart mobile phone to complete to play.The trip
Play is a typical non real-time high-volume data transmission and the cooperation of real-time small lot data transmission to complete correlation function
A process.When being played, need to rouse machine and the smart mobile phone audio file that be played simultaneously one identical, simultaneously
The information such as the percussion of drum generator terminal drum are required to be transferred to smart mobile phone in real time.It is broadcast since drum is confidential with smart mobile phone needs
Same audio file is put, so smart mobile phone is needed first to give audio file transmissions to drum machine before being played.Transmit audio
File is the high-volume data not high to requirement of real-time, and the need can be met by being transmitted using the TCP connection set up
It asks.Game process can be proceeded by after this, and the process is higher to requirement of real-time, while the broadcasting control of audio
The information such as system, the drum percussion of drum machine are all a small amount of data, can meet the demand using the bluetooth connection of foundation.Therefore,
By using two kinds of wireless data transmission modes of bluetooth and WiFi, while the demand of real-time and volume of transmitted data is taken into account.
How low prolong is taken into account come the radio data transmission method that the present invention is further explained by specific embodiment again below
When high-speed and low-power consumption high-speed.
Embodiment one
In this embodiment, radio data transmission method of the invention is applied between electronic musical instrument and intelligent terminal, root
Suitable data transfer mode is selected according to the data volume transmitted and to the requirement of real-time of transmission.Specifically, such as Figure 11 institutes
Show, include the following steps：
111) when carrying out data transmission between electronic musical instrument and intelligent terminal, first determine whether that the real-time of data transmission will
It asks, i.e., data average delay whether is required to be not more than the first predetermined threshold value；If desired certain real-time, then it is wireless using first
Communication mode；
If 112) do not need to certain real-time, then judge the data volume size to be transmitted；If data volume size is little
In the 4th predetermined threshold value, such as 80 bytes；Then using the first communication, otherwise big data quantity transmission needs the logical of high-speed
Letter mode, i.e., using the second communication.
Embodiment two
In this embodiment, radio data transmission method of the invention is applied between electronic musical instrument and intelligent terminal, solution
The problem of low-power consumption/high-speed of having determined.This is because the first communication is typically low-power consumption, i.e. power consumption is less than or equal to
90mW, therefore, in the higher occasion of power consumption requirements, using the first communication.When wireless data transmission has high-speed
Requirement when, using high-power carry out high-speed transfer, i.e., using the second communication.Specifically, as shown in figure 12, including
Following steps：
121) when carrying out data transmission between electronic musical instrument and intelligent terminal, the power consumption for judging whether there is data transmission will
It asks, i.e., power consumption whether is required to be not more than a certain predetermined threshold value；
It is otherwise wireless using second using the first communication if 112) power consumption requirements with data transmission
Communication mode.
In conclusion the radio data transmission method and system of the present invention, electronic musical instrument and intelligent terminal are according to different
Wireless transmission demand carries out the wireless data transmission between electronic musical instrument and intelligent terminal using different communications,
So as to take into account the requirement of real-time and transmission rate, the requirement of power consumption or transmission rate is taken into account；Greatly improve user experience.
