Embodiment
Purpose, technical scheme and technique effect for a better understanding of the present invention, below in conjunction with drawings and examples
Further explaining illustration is carried out to the present invention.State simultaneously, embodiments described below is only used for explaining the present invention, not
For limiting the present invention.
In one embodiment, as shown in figure 1, the control method flow chart of the toy car for an embodiment, including step：
S101, when receiving rhythm control mode instruction, obtain the sound instruction of the sound transducer collection of toy car
Tempo characteristic information.
When the dolly control chip of toy car receives rhythm control mode instruction, user, which can audible instruction, to come
Control the action of toy car.
Wherein, tut instruction is the sound with tempo characteristic information, and user can pass through the mode such as clap one's hands, beat a drum
The sound with tempo characteristic information is produced to control toy car.The tempo characteristic information of sound instruction can be between beat
Time interval and/or beat number.
In one embodiment, user can be by being arranged on toy car vehicle body or being arranged on pattern on a remote control
The control model of switching switch selection toy car.The toy car is to reduce to form with certain proportion by vehicle configuration outward appearance
The toy for amusement of children, can be the type of drive such as mechanical, electrodynamic type.After user selects rhythm control pattern, mould
Formula switching switch sends rhythm control mode instruction to the dolly control chip of toy car, and dolly control chip receives beat
Sound instruction, which is connected, after control model instruction obtains circuit.Sound instruction obtains circuit and gathers user by the first sound transducer
Sound instruction the sound instruction collected is converted into the first analog signal, simultaneously, at above-mentioned first analog signal
Reason, and the first analog signal is sent to dolly control chip.
S102, according to the time interval between each two beat in the tempo characteristic information, generate binary coding.
It is above-mentioned to select time interval to generate binary-coded mode, it is that tempo characteristic information is converted into binary system to compile
The preferred embodiment of code.A time threshold t is preset, by the time interval between above-mentioned each two beat and default time
Threshold value t is compared, and the size at different time interval is converted into binary coding.It is equally possible that the number by beat
It is converted into binary coding.
In one implements, tut instruction obtains the I/O mouths that the first analog signal is passed through dolly control chip by circuit
Transmit to the ad modular converters of chip, dolly control chip and the first analog signal received is converted into data signal, and it is right
Data signal is handled to obtain the digital signal waveform figure of sound instruction.As shown in Fig. 2 illustrate for binary-coded generation
Figure, abscissa represent the time, and ordinate represents digitized electric signal amplitude.A time threshold t is preset, by setting reset
" 1 " threshold line limits electric signal amplitude, obtains the coxcomb plot of the data signal of sound instruction, the time difference between each two sawtooth
Value is exactly the time interval between each two beat, and different time interval is compared with default time threshold t, if time interval
More than default time threshold t, binary coding " 0 " is obtained, if time interval is less than or equal to default time threshold t, is obtained
Binary coding " 1 ", if or, time interval be more than default time threshold t, binary coding " 1 " is obtained, if time interval is small
In equal to default time threshold t, binary coding " 0 " is obtained.
