Description

Technical Field

[0001] The utility model relates to the technical field of model aircraft remote controllers, in particular to a voice interaction circuit. Background Art

[0002] With the development of model aircraft, model aircraft have been loved by more and more people. An important point for the normal operation of model aircraft is how to convert different voltages and batteries into stable voltage and current for use in model aircraft. For example, when installing batteries into model aircraft, it is necessary to measure the battery power. If the battery power is insufficient when connected to the model aircraft, it will cause damage to the battery. However, this detection method is more troublesome.

[0003] Among them, the flight operation instructions of the model aircraft are input through the model aircraft remote control. Specifically, the input of the model aircraft remote control is generally operated through joysticks, rocker arms, etc. In the actual operation of the model aircraft flight, it is often not necessary to operate one of the structures alone. For example, to control the model aircraft to dive to the right front, both hands are required to control the three control structures of forward, right turn, and descent at the same time. In this difficult flight process, it is also necessary to control the specific right turn angle, the descent speed, etc., and these actions require the cooperation of both hands to complete. If it is necessary to take quick photos during this continuous high-speed flight, it is necessary to free up fingers to operate and press the shutter to take photos. This leads to certain hidden dangers in the operation of high-speed flying models.

[0004] Therefore, it is necessary to propose a voice interaction circuit to improve the above-mentioned defects. Utility Model Content

[0029] The present invention is further described below in conjunction with the accompanying drawings and implementation modes:

[0030] like Figure 1 and Figure 2 As shown, a voice interaction circuit includes a main processing chip 10, a voice recognition chip 20, a voice input circuit 30 and a voice output circuit 40, wherein the main processing chip 10 is used to receive voice data and process output instructions, and the voice recognition chip 20 is used to realize voice interaction. In addition, the voice input circuit 30 is connected to the voice recognition chip 20, and the voice input circuit 30 is used to obtain voice signals. The voice output circuit 40 is respectively connected to the voice recognition chip 20 and the main processing chip 10, and the voice output circuit 40 is used to output voice signals.

[0031] In this embodiment, the user obtains the user's voice signal through the voice input circuit 30, and transmits the voice signal to the voice recognition chip 20 for recognition and processing. Then, the main processing chip 10 receives the voice signal processed by the voice recognition chip 20, processes and recognizes these signals, and generates corresponding operation instructions. The corresponding structure is controlled to perform corresponding operations through the operation instructions, thereby realizing the control of the flight of the model aircraft through voice input instructions. Compared with manually operating the peripheral structure to achieve the purpose of outputting instructions to the model aircraft, the convenience of inputting instructions to the model aircraft is higher through the use of the utility model, thereby solving the problem that it is difficult for the user to manually adjust the camera angle when operating the model aircraft for a difficult flight.

[0032] It should be explained that, first, the main processing chip 10 is responsible for receiving and processing voice data and outputting corresponding instructions. Specifically, it recognizes, analyzes and judges the voice data through specific algorithms and programs, thereby generating corresponding control instructions. In other embodiments, these instructions may be operation commands for other circuits or devices, or data for further processing; second, the voice recognition chip 20 is a key part of realizing voice interaction. Specifically, it is connected to the voice input circuit 30 and receives the original voice signals from the voice input circuit 30. After preprocessing, these signals are converted into digital signals suitable for recognition. Then, the voice recognition chip 20 uses its built-in algorithms and models to process these signals. The voice input circuit 30 performs in-depth analysis and recognition on some digital signals and converts them into text or instructions; third, the main function of the voice input circuit 30 is to obtain and preliminarily process the voice signal. Specifically, when there is a voice signal input, the circuit will perform noise reduction, amplification and other processing on it, and then transmit it to the voice recognition chip 20; fourth, the voice output circuit 40 is responsible for outputting the processed voice signal to the user. Specifically, the voice output circuit 40 is connected to the voice recognition chip 20 and the main processing chip 10 respectively, and receives data and instructions from both. After receiving the data or instructions, the voice output circuit 40 will perform necessary processing (such as synthesis, encoding, etc.) on it, and then play the signal through a speaker or other sound output device.

[0033] It should be added that the utility model solves the problem that other instructions cannot be inputted under the premise of ensuring safe flight during the operation of the model aircraft. Specifically, in the traditional model aircraft flight, the operator needs to send instructions through a remote control or other manual device to control the flight of the model aircraft. However, in some cases, the operator may need to input other instructions or perform other operations, such as adjusting the camera angle of the model aircraft, obtaining the real-time status information of the model aircraft, etc. These operations may distract the operator's attention and increase the flight risk. Therefore, by introducing the voice interaction circuit of the utility model, the operator can use voice instructions to control the additional functions of the model aircraft while ensuring safe flight, which means that the operator can easily adjust the camera angle of the model aircraft, view the real-time status information of the model aircraft or perform other related operations during the operation of the model aircraft without using traditional manual devices, thereby improving the safety of flight through the utility model, and providing the operator with a more convenient and intelligent control experience. In addition, the utility model not only realizes an efficient voice interaction function, but also provides a practical solution for solving specific problems in the operation of the model aircraft flight, so that the operator can focus more on the flight mission and easily perform other related operations when needed, thereby improving the safety and convenience of flight.

One end of the third resistor 51 is connected to the power supply, and the other end of the third resistor 51 is respectively connected to the third capacitor 52, the fourth capacitor 53 and pin 2 of the voice recognition chip 20. The other end of the third capacitor 52, the other end of the fourth capacitor 53, and one end of the fifth capacitor 54 are all grounded, and the other end of the fifth capacitor 54 is connected to pin 1 of the voice recognition chip 20.

[0036] In this embodiment, the power input circuit 50 is connected to the voice recognition chip 20 to provide a stable power supply for the voice recognition chip 20, wherein the power input circuit 50 includes a third resistor 51, a third capacitor 52, a fourth capacitor 53 and a fifth capacitor 54, and these components work together to ensure a stable power supply; specifically, one end of the third resistor 51 is connected to the power supply, and the other end is respectively connected to the third capacitor 52, the fourth capacitor 53 and the 2nd pin of the voice recognition chip 20. The other end of the third capacitor 52, the other end of the fourth capacitor 53, and one end of the fifth capacitor 54 are all grounded. The other end of the fifth capacitor 54 is connected to the 1st pin of the voice recognition chip 20.

[0037] For further reference, Figure 1 The voice input circuit 30 includes a microphone module 31, a first capacitor 32, a second capacitor 33, a first resistor 34 and a second resistor 35. One end of the first capacitor 32 is connected to the pin 21 of the voice recognition chip 20, and the other end is respectively connected to the first resistor 34 and the positive pin of the microphone module 31, and the other end of the first resistor 34 is connected to the pin 22 of the voice recognition chip 20; one end of the second capacitor 33 is connected to the pin 20 of the voice recognition chip 20, and the other end is respectively connected to the second resistor 35 and the negative pin of the microphone module 31, and the other end of the second resistor 35 is grounded.

[0038] In this embodiment, the design of the voice input circuit 30 enables the user to more conveniently input other instructions during the operation of the model aircraft while ensuring safe flight. Through this circuit design, the user can use voice commands to control the additional functions of the model aircraft without distracting attention to operate traditional remote controls or manual devices. Specifically, the microphone module 31 is used to collect the user's voice signal, the first capacitor 32 and the second capacitor 33 play a filtering role, remove noise and clutter in the signal, and improve the accuracy of voice recognition. The first resistor 34 and the second resistor 35 are used to adjust the signal level so that the signal adapts to the input range of the voice recognition chip 20. It should be added that the voice input circuit 30 has a stable power supply function. Through the connection of the first capacitor 32, the second capacitor 33 and the first resistor 34 and the second resistor 35, the circuit can provide a stable power supply for the microphone module 31 to ensure that the collection of voice signals is not affected by power supply fluctuations.

[0039] It should be explained that the utility model, through the design of the voice input circuit 30, allows the operator to output operating instructions through voice when it is unable to frequently use a traditional remote control or manual device to input other instructions, thereby controlling additional functions of the model aircraft, such as adjusting the camera angle, viewing real-time status information, etc., thereby improving the convenience and safety of flight.

[0041] In this embodiment, through the connection between the voice output circuit 40 and the voice recognition chip 20, the main processing chip 10 can convert the received instructions or data into voice signals. The fourth resistor 41 and the fifth resistor 42 are respectively connected to the 63rd pin and the 64th pin of the main processing chip 10 to play the role of signal transmission. When the main processing chip 10 needs to output a voice signal, it will send the signal to these resistors, and then pass it to other parts of the voice output circuit 40 through the resistors.

[0043] In this embodiment, the addition of the sixth capacitor 55 and the seventh capacitor 56 further enhances the stability and reliability of the voice interaction circuit, thereby more effectively solving the problem of being unable to input other instructions while ensuring safe flight during the operation of the model aircraft. Specifically, one end of the sixth capacitor is grounded, and the other end is connected to pin 3 of the voice recognition chip 20. This connection method helps to stabilize the operating voltage of the voice recognition chip 20 and reduce the impact of power supply fluctuations on its performance. In addition, one end of the seventh capacitor 56 is connected to pin 4 of the voice recognition chip 20, and the other end is connected to pins 5 and 8 of the voice recognition chip 20.
