Embodiment 1
[0031] see figure 1 A flow chart of a voice control method is shown, the method is executed by a controller, and the controller is wirelessly connected with the actuator, and the method includes the following steps:
[0032] Step S102, receiving the voice signal sent by the user through the voice collection device; wherein, the audio collection device may be a microphone;
[0033] Step S104, according to the pre-set garbage vocabulary, the voice signal is filtered; wherein, the garbage vocabulary is stored in words that have nothing to do with the target recognition keywords;
[0034] For example, when the above-mentioned target recognition keyword is a control command, the voice signal sent by the user contains control commands, such as "forward", "backward", etc.; but the user may not only issue control commands, but also some modal particles, or Other words that are not related to control commands, such as "forward", "ah" and "immediately" in "immediately back" are not con...
Embodiment 2
[0046] see figure 2 A flow chart of a balance car control method is shown, the method is executed by an actuator, and the actuator is wirelessly connected to the controller, and the method includes the following steps:
[0047] Step S202, receiving the command code sent by the controller;
[0048] Step S204, acquiring motion state data of the balance car through a gyroscope; wherein, the gyroscope can be a six-axis gyroscope;
[0049] Step S206, generating a pulse control signal corresponding to the command code according to the motion state data;
[0050] Step S208, sending the pulse control signal to the motor driver, so that the motor driver controls the movement of the balance car according to the pulse control signal.
[0051] A balance car control method provided by an embodiment of the present invention is executed by an actuator, and generates a pulse control signal corresponding to the command code sent by the controller according to the motion state data obtained ...
Embodiment 3
[0054] In order to understand the above-mentioned voice control method and balance car control method in more detail, the embodiment of the present invention provides a wireless control method for a two-wheel balance car based on voice recognition; this method can be executed by the hardware system of a two-wheel balance car, in order to facilitate To understand the above-mentioned wireless control method of the two-wheeled self-balancing vehicle based on speech recognition, the embodiment of the present invention first describes the hardware system of the above-mentioned two-wheeled self-balancing vehicle.
[0055] see image 3 The structural diagram of the hardware system of a kind of two-wheel balancing vehicle shown; Six-axis gyroscope 308, Arduino Leonardo controller 310, A4988 stepper motor driver 312 and 42-type stepper motor 314; wherein, LD3320 chip 302, Arduino atmega2560 controller 304, HC-05 Bluetooth host module 306 are set on the double-wheel balance In the remo...
