Description

Technical Field

[0001] The present invention relates to the technical field of smart clothing, and in particular to a Bluetooth control method and device for heating clothing. Background Art

[0002] Heating clothing is a kind of clothing or accessories composed of ordinary or special clothing and heating devices. Common heating clothing in the market include: heating jackets, heating pants, heating gloves, heating socks, etc. Generally speaking, there should be no wired connection between clothing in different parts. On the one hand, it is difficult to take off the clothes, and on the other hand, it is not aesthetically pleasing. Therefore, in the conventional control logic, each product in the whole set of heating clothing will be equipped with a separate control button to control the on and off of the power supply. The above-mentioned separate control is not only cumbersome, but also for socks on the feet, you even need to bend down to turn on the button. Or, when the clothes worn by the user's upper body are relatively thick, even the buttons on the pants cannot be operated in an upright state, causing inconvenience in use.

[0003] CN111493388A discloses a smart clothing based on microservice management, which can communicate with people through voice recognition VUI technology, and control the automatic heating and heat preservation of clothing through the conversation. However, the smart clothing can only perform voice control on the top with a microphone, and cannot control the heating device in the relatively long-distance pants and socks due to the limitation of environmental noise and distance. Summary of the invention

[0004] In view of the inconvenience of controlling multiple heating products on the whole body, the present invention proposes a Bluetooth control method and device for heating clothing, aiming to control multiple heating devices through a single voice input.

[0005] In order to solve the above technical problems, the first aspect of the present invention provides a Bluetooth control method for heating clothing, comprising the following steps:

[0006] The voice module acquires a voice signal and triggers the generation of a control instruction according to a characteristic signal contained in the voice signal;

[0007] The host determines the type of the control instruction. If the control instruction belongs to Class I control instruction, the host sends the Class I control instruction to the upper garment heating device via wired transmission. The Class I control instruction triggers the upper garment heating device to perform opening and closing operations. If the control instruction belongs to Class II control instruction, the Class II control instruction is sent to the Bluetooth broadcast channel. Each slave receives the Class II control instruction from the Bluetooth broadcast channel, and parses and identifies the address code contained in the Class II control instruction. The address code only triggers one of the slaves to control the corresponding non-upper garment heating device to perform opening and closing operations.

[0008] In some implementations, the control instruction includes an identification code, the host determines the type of the control instruction according to the identification code, and matches a corresponding transmission channel for the control instruction according to the type.

[0009] In some implementations, before the control instruction is triggered to be generated, it is continuously determined whether the ambient sound contains a wake-up statement, and if so, the voice module is woken up, and if not, the voice module continues to sleep.

[0010] In some implementations, when the voice module is in the awake state, if no control instruction is triggered to be generated within a specified time period, the voice module enters sleep mode.

[0011] In some implementations, the prescribed time duration is set to 10-60 seconds.

[0012] In some embodiments, the address code triggers at least two of the slave machines to control the corresponding non-upper-body heating devices to perform opening and closing operations. After the non-upper-body heating devices perform the opening and closing operations, the corresponding slave machines all send feedback signals to the host. If the host does not receive all of the feedback signals within a preset time, the second type of control instructions are resent to the Bluetooth broadcast channel.

[0013] In some embodiments, the voice module includes a writable voice comparison library, extracts the feature signal from the voice signal, and converts it into text. If the text matches a keyword in the voice comparison library, it triggers the generation of a corresponding control instruction.

[0014] A second aspect of the present invention provides a Bluetooth control device for heating clothing, comprising:

[0015] A voice module, used to obtain a voice signal and trigger the generation of a control instruction according to a target signal contained in the voice signal;

[0016] The host is used to determine the type of the control instruction. If the control instruction belongs to a type of control instruction, the type of control instruction is sent to the upper garment heating device via wired transmission. The type of control instruction triggers the upper garment heating device to perform opening and closing operations. If the control instruction belongs to a type of control instruction, the type of control instruction is sent to a Bluetooth broadcast channel. Each slave receives the type of control instruction from the Bluetooth broadcast channel, and parses and identifies the address code contained in the type of control instruction. The address code only triggers one of the slaves to control the corresponding non-upper garment heating device to perform opening and closing operations.

[0017] The third aspect of the present invention proposes a Bluetooth control device for heating clothing, which includes a memory, a processor and a communication module, wherein the memory is used to store executable program code; the processor is coupled to the memory; the processor calls the executable program code stored in the memory to execute the above-mentioned Bluetooth control method for heating clothing.

[0018] A fourth aspect of the present invention provides a computer storable medium, wherein the computer storage medium stores computer instructions, and when the computer instructions are called, they are used to execute the above-mentioned heating clothing Bluetooth control method.

[0019] The beneficial effects of the present invention are: the host controls the non-upper-body heating device to perform opening and closing operations through Bluetooth broadcasting, thereby reducing the impact of environmental noise, increasing the distance of voice control, and effectively avoiding bending over and scenes where it is inconvenient to operate with hands.

[0029] Embodiment 1

[0030] This embodiment proposes a Bluetooth control method for heated clothing, in which the host controls the non-upper-body heating device to perform on-off operations through Bluetooth broadcasting, thereby reducing the impact of environmental noise, increasing the distance of voice control, and effectively avoiding bending over and scenes where it is inconvenient to operate with hands.

[0031] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for controlling heating clothing with Bluetooth according to an embodiment of the present invention. Figure 1 As shown, the following steps are included:

[0032] The voice module obtains the voice signal and triggers the generation of control instructions according to the characteristic signals contained in the voice signal;

[0033] The host determines the type of control instruction. If the control instruction belongs to Class I control instruction, the Class I control instruction is sent to the upper garment heating device via wired transmission. The Class I control instruction triggers the upper garment heating device to perform opening and closing operations. If the control instruction belongs to Class II control instruction, the Class II control instruction is sent to the Bluetooth broadcast channel. Each slave receives the Class II control instruction from the Bluetooth broadcast channel, and parses and identifies the address code contained in the Class II control instruction. The address code only triggers one slave to control the corresponding non-upper garment heating device to perform opening and closing operations.

[0034] There are two main ways to implement speech recognition: one is to call the speech development kit directly in the embedded processor; the other is to expand the speech chip around the embedded processor. The first method has a large amount of program, complex calculations, requires a large amount of processor resources, and a long development cycle; the second method is relatively simple, only needs to pay attention to the interface part of the voice chip connected to the microprocessor, the structure is simple, easy to build, the calculation burden of the microprocessor is greatly reduced, the reliability is enhanced, and the development cycle is shortened. Therefore, this embodiment uses the solution of the speech module. The above-mentioned speech module is non-specific person recognition. Non-specific person recognition refers to the recognition object for most users. In this embodiment, it is mainly used to extract feature signals from speech signals and generate corresponding control instructions. For example, if the user outputs the speech "heating the top", the speech module recognizes the keywords "top" and "heating" in the sentence, and then outputs the corresponding control instructions according to the matching. Similarly, if the user outputs the speech "heating the pants", the speech module recognizes the keywords "pants" and "heating" in the sentence, and then outputs the corresponding control instructions according to the matching.

[0035] The above host mainly includes computing functions and Bluetooth transmission functions. In this embodiment, the host receives control instructions from the voice module, first judges the attributes of the control instructions, and classifies them as Class I control instructions or Class II control instructions, and then selects line control or Bluetooth broadcasting according to its attributes. According to the tasks that the host needs to undertake, it can be equipped with a microprocessor chip as a computing module and a Bluetooth SOC as a signal sending module for transmitting control instructions.

[0036] The above-mentioned slave only includes a one-way Bluetooth transmission function and can only passively receive control instructions sent intermittently in the broadcast channel.

[0037] In this embodiment, the upper garment heating device is embedded in the voice module and the host, and has the functions of voice recognition and Bluetooth communication. Other non-upper garment heating devices (including but not limited to pants, gloves or socks) are embedded in the slave machine, and only have the Bluetooth communication function. Through the recognition handshake between the host and each slave machine, when the user puts on the upper garment, the control instruction should first be generated through the recognition function of the voice module, and then the host machine transmits the control instruction to different channels according to the situation. For the control instruction for the upper garment heating device, the host machine directly controls the upper garment heating device by line. For the control instruction for the non-upper garment heating device, the host machine broadcasts the control instruction to each slave machine through Bluetooth communication. Only one slave machine finally executes the corresponding operation, so that the slave machine can be indirectly and quickly controlled, thereby avoiding the problems of environmental noise and control distance, while reducing the hardware modules used by the slave machine and reducing the production cost.

[0038] Embodiment 2

[0039] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of another method for controlling heating clothing with Bluetooth according to an embodiment of the present invention. Figure 2 As shown, the following steps are included:

[0040] Before the control instruction is triggered, it is continuously determined whether the ambient sound contains a wake-up sentence. If so, the voice module is awakened. If not, the voice module continues to sleep.

[0041] When the voice module is in the wake-up state, if no control command is triggered within the specified time, the voice module goes to sleep, and the specified time is set to 10-60 seconds. In this embodiment, the generation of control instructions is used as the trigger condition for the voice module to enter the sleep state, rather than simply using the wake-up statement as the trigger condition for the voice module to extend the wake-up state, which can prevent the voice module from going to sleep while the user continues to issue voice control. Assuming that the specified time is set to 10 seconds, during which the user needs to send multiple voice signals, according to the general control logic, if the user does not issue a wake-up statement within 10 seconds, the voice module will sleep by itself. Therefore, in this embodiment, within the timing range of the specified time, if the user is detected to send a voice signal, the specified time is reset, that is, the countdown is restarted. Obviously, the sleep trigger logic proposed in this scheme will prevent the voice module from going to sleep during the actual operation of the user, which greatly improves the user experience.

[0042] The voice module obtains the voice signal and triggers the generation of control instructions based on the characteristic signals contained in the voice signal; the control instruction contains an identification code, and the host determines the type of control instruction based on the identification code and matches the corresponding transmission channel for the control instruction based on the type. The voice module contains a writable voice comparison library, which extracts the characteristic signal from the voice signal and converts it into text. If the text matches the keywords in the voice comparison library, the corresponding control instruction is triggered.

[0043] The host determines the type of control instruction. If the control instruction belongs to Class I control instruction, the Class I control instruction is sent to the upper garment heating device via wired transmission. The Class I control instruction triggers the upper garment heating device to perform opening and closing operations. If the control instruction belongs to Class II control instruction, the Class II control instruction is sent to the Bluetooth broadcast channel. Each slave receives the Class II control instruction from the Bluetooth broadcast channel, and parses and identifies the address code contained in the Class II control instruction. The address code only triggers one slave to control the corresponding non-upper garment heating device to perform opening and closing operations.

[0044] In another optional example, a one-to-many control scheme of the host is also provided. The address code triggers at least two slaves to control the corresponding non-upper heating device to perform the opening and closing operation. After the non-upper heating device performs the opening and closing operation, the corresponding slaves all send feedback signals to the host. If the host does not receive all the feedback signals within the preset time, the second-class control instruction is resent to the Bluetooth broadcast channel. In this scheme, since a second-class control instruction needs to trigger the control of two slaves, the data packet of the second-class control instruction will become larger, and the risk of transmission failure will increase. Therefore, the corresponding slave needs to send a feedback signal to the host. The host is responsible for verifying the feedback signal and triggering the operation of resending the second-class control instruction according to the situation. In addition, the preset time should be set to 1 second or shorter.

[0045] The host of this embodiment mainly includes computing functions and Bluetooth transmission functions. In this embodiment, the host receives control instructions from the voice module, first determines the attributes of the control instructions, classifies them into Class I control instructions or Class II control instructions, and then selects line control or Bluetooth broadcasting according to their attributes. Secondly, the host also needs to determine the collected feedback signal.

[0046] The slave device of this embodiment includes a two-way Bluetooth transmission function, and can passively receive control instructions sent intermittently in the broadcast channel, and can also return a feedback signal to the host device after receiving the control instructions.

[0049] The voice module 301 is used to obtain a voice signal and trigger the generation of a control instruction according to a target signal contained in the voice signal;

[0050] The host 302 is used to determine the type of control instruction. If the control instruction belongs to a type of control instruction, the type of control instruction is sent to the upper garment heating device 303 via wired transmission. The type of control instruction triggers the upper garment heating device 303 to perform opening and closing operations. If the control instruction belongs to a type of control instruction, the type of control instruction is sent to the Bluetooth broadcast channel. Each slave 304 receives the type of control instruction from the Bluetooth broadcast channel, and parses and identifies the address code contained in the type of control instruction. The address code only triggers one slave 304 to control the corresponding non-upper garment heating device 305 to perform opening and closing operations.
