Problems solved by technology

[0003] The existing voice-controlled two-wheeled balance car usually uses a voice chip to understand and analyze the original voice, and then converts it into a control signal and sends it to the single-chip microcomputer. Control purpose; however, the above-mentioned control method based on speech recognition has many problems such as inconvenient use, inaccurate recognition, lack of humanization in system design, etc.
[0004] Aiming at the problem of low accuracy of existing voice control methods, no effective solution has been proposed

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...

Abstract

The invention provides a speech control method and a speech control device, a balance car control method and a balance car control device, and a balance car, wherein the speech control method is executed by a controller. The method comprises the following steps: receiving speech signals transmitted from a user by virtue of a speech acquisition device; in accordance with a preset rubbish word list, filtering the speech signals, wherein words, which are irrelevant to target identification key words, are saved in the rubbish word list; comparing the filtered speech signals with the target identification key words which are saved in a preset key word list, so that a speech recognition result is generated, wherein the speech recognition result contains control command; researching command codes, which correspond to the control commands, from a preset command code list; and transmitting the command codes to an executor, so that the executor can control the balance car to move in accordance with the speech recognition result. According to the invention, the speech recognition result can be rapidly and accurately acquired, so that the balance car can be controlled in accordance with the result; therefore, efficiency and precision of controlling the balance car can be improved.

Description

technical field [0001] The invention relates to the technical field of embedded control, in particular to a voice control method and device, a balance car control method and device, and a balance car. Background technique [0002] With the rapid development of speech recognition technology and the continuous improvement of practicability, more and more devices in life are endowed with "voice" functions. For example, in smart homes, users can control various furniture through voice; in children's toys, voice interaction is given the important task of education. The two-wheel balance car uses the gyroscope or acceleration sensor inside the car to detect the change of the body posture, and uses the controller to accurately drive the motor to adjust to maintain the balance of the system. [0003] The existing voice-controlled two-wheeled balance car usually uses a voice chip to understand and analyze the original voice, and then converts it into a control signal and sends it to...
