[0002] Current remote control systems primarily transmit signals via push-button switches. For example, remote control handles mostly use touch buttons on the handle's casing or DIP switches. Due to space limitations, the number of buttons cannot be excessive, resulting in a limited number of controllable functions and impacting the user experience. Furthermore, users must hold the remote and press buttons to operate it, which restricts their hands and hinders usability in certain situations. Therefore, improvements are necessary. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a wireless remote control system based on a voice recognition module.

[0004] The technical solution is as follows: a wireless remote control system based on a voice recognition module, including a transmitting unit and a receiving unit.

The output terminal of the signal receiving module is connected to the input terminal of the decoding module, and the output terminal of the decoding module is connected to the control module. The signal transmitting module and the signal receiving module are connected via radio or infrared. The input terminal of the encoding module is connected to the output terminal of a first voice recognition module through a converter. The first voice recognition module is equipped with a first microphone and a first speaker. A second voice recognition module is connected in series between the output terminal of the decoding module and the input terminal of the control module. The second voice recognition module is equipped with a second microphone and a second speaker.

[0005] Furthermore, the converter is an electronic switching circuit comprising at least one optocoupler, at least one transistor, or at least one channel of an analog switching integrated circuit.

[0006] Furthermore, both the first speech recognition module and the second speech recognition module are offline speech recognition modules with wake-up words and command words embedded in them.

[0007] Furthermore, the control module is a relay module or a MOS switch module used to control the load.

[0008] Compared with existing technologies, this utility model has the following advantages: it is reasonably designed, has a simple structure, and is easy to manufacture. In use, it can be remotely operated using buttons, and can also be remotely controlled via voice commands, greatly facilitating operation.

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] Example 1: Refer to Appendix Figure 1 and Figure 2A wireless remote control system based on a voice recognition module includes a transmitting unit 1 and a receiving unit 2. The transmitting unit 1 is equipped with an encoding module 11, a control button 12, and a signal transmitting module 13. The control button 12 is connected to the input terminal of the encoding module 11, and the output terminal of the encoding module 11 is connected to the signal transmitting module 13. The receiving unit 2 is equipped with a signal receiving module 21, a decoding module 22, and a control module 23. The output terminal of the signal receiving module 21 is connected to the input terminal of the decoding module 22, and the output terminal of the decoding module 22 is connected to the control module 23. The signal transmitting module 13 and the signal receiving module 21 are connected via radio wave 6 or infrared wave. The input terminal of the encoding module 11 is connected to the output terminal of a first voice recognition module 4 via a converter 3. The first voice recognition module 4 is equipped with a first microphone 41 and a first speaker 42. A second voice recognition module 5 is connected in series between the output terminal of the decoding module 22 and the input terminal of the control module 23. The second voice recognition module 5 is equipped with a second microphone 51 and a second speaker 52. The entire transmitting unit 1 is installed in a housing, forming a whole, similar or the same as the style of existing ordinary wireless remote controls. The first microphone 41 and the first speaker 42 are set on the housing, which facilitates receiving voice commands and issuing response sounds. In addition, the first microphone 41 is preferably a lapel microphone, which is connected to the first voice recognition module 4 through a socket set on the housing. The remote control can be placed in a pocket or hung on the waist, and the lapel microphone can be clipped to the collar of the shirt. This way, the hands can be freed when using it, which is very convenient.

[0012] The transmitting unit 1 and the receiving unit 2 can be used independently. When the transmitting unit 1 is used alone, it can be used in conjunction with electrical appliances that already have remote control functions to replace the original remote control for controlling the operation of the electrical appliances. When the receiving unit 2 is used alone, the operation of the electrical appliances can be controlled directly by voice commands without the use of a remote control, making it flexible and convenient to use.

[0013] The converter 3 is an electronic switching circuit; the electronic switching circuit includes at least one resistor R and an optocoupler Q (attached). Figure 2 Taking one optocoupler as an example, the positive input terminal of the optocoupler Q is connected to one end of the resistor R, and the other end of the resistor R is the input terminal of the electronic switch circuit. The negative input terminal of the optocoupler Q is grounded and used to connect to the output terminal of the first voice recognition module 4. The two output terminals of the optocoupler Q are the output terminals of the electronic switch circuit and are used to connect to the input terminal of the encoding module 11. The electronic switch circuit is provided at least one to be suitable for various control applications.

[0014] Both the first speech recognition module 4 and the second speech recognition module 5 are offline speech recognition modules with pre-set wake words and command words. The wake words and command words are pre-set by the speech recognition module manufacturer and can be purchased directly.

[0015] The control module 23 is a relay module or MOS switch module used to control the load, which can be purchased directly.

[0016] Example 2: In this example, the signal transmitting module 13 in the transmitting unit 1 and the signal receiving module 21 in the receiving unit 2 are connected via infrared 6, and the rest is the same as in Example 1. This example can be applied to appliances with infrared remote control, such as televisions, electric fans, and air conditioners.

[0017] In use, the transmitting unit 1, like a wireless remote control in the prior art, can trigger the encoding module 11 and transmit wireless signals through the signal transmitting module 13 via the control button 12. The transmitting unit 1 can also receive multiple command words from the user. After the command words are recognized by the first voice recognition module 4, the encoding module 11 is triggered by the converter 3, and then the wireless signal is transmitted through the signal transmitting module 13. In the receiving unit 2, the signal receiving module 21 receives the wireless signal, decodes it through the decoding module 22, and then controls the appliance through the second voice recognition module 5 and the control module 23. The receiving unit 2 can control the appliance directly via voice commands without using a remote control.

[0018] This utility model is reasonably designed, simple in structure, and easy to manufacture. In use, it can be remotely operated using buttons, or remotely controlled via voice commands, greatly facilitating operation. The transmitting and receiving units of this utility model can be used independently. When used alone, the transmitting unit can work with existing remote-controlled appliances to replace the original remote control. When used alone, the receiving unit can control appliances directly via voice commands without a remote control, offering flexibility and convenience.

[0019] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
