Description
Technical Field
The invention relates to a system and a method for intelligently controlling a skylight by voice.
Background
The existing method for controlling the automobile skylight by voice only can realize specific adjusting instructions, such as tilting, full opening and full closing, and the operations of opening half and opening one third of a small part of automobile types can be realized. The skylight control unit is limited in execution action only under a specific signal instruction, and is not flexible enough, if other instructions are added, the skylight control unit needs to be modified according to the current instruction, not only is frequent change required on software, but also has certain limitation in use of users.
Compared with the method described in CN108749540A, CN108749540A also uses voice to control skylights, but it emphasizes the physical topology and physical operation implementation, and although the use of signals is also referred to in the middle, no specific signal design is involved. The method focuses on a signal design level, allows a user to control the skylight by using a language based on a relative position or an absolute position by optimizing the design of the signal level, and realizes a more flexible control mode. This is not shown in CN 108749540A.
In contrast to the method described in CN107444317A, CN107444317A emphasizes the part of semantic analysis and safety in use, which is not the focus of the method emphasizing the design and use of position command signals for driving the movement of the position of the skylight. This is not reflected by CN 107444317A.
Compared with the method described in CN203472744U, CN203472744U can only realize opening the skylight, closing the skylight and tilting the skylight, and although the end of the article emphasizes that "without departing from the technical principles of the present invention, a plurality of improvements and decorations can be made, essentially, only limited control is realized, and control of any opening degree of the skylight cannot be realized. The method realizes the voice control of any opening degree of the skylight through the design on the signal level.
Compared with the method described in CN110060671A, CN110060671A can also implement only limited control schemes, and also needs voice self-learning, which increases the use cost. The method realizes flexible voice control through signal design.

Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
as shown in figure 1, the intelligent voice control skylight system comprises a voice acquisition module 1-1, a voice instruction conversion module 1-2, a skylight control unit 1-3, a voice instruction control module 1-3-1, a motor driver 1-4 and a Hall sensor 1-5, wherein the output of the voice acquisition module 1-1 is connected with the input of the voice instruction conversion module 1-2, the output of the voice instruction conversion module 1-2 is connected with the input of the voice instruction control module 1-3-1 in the skylight control unit 1-3, the output of the skylight control unit 1-3 is connected with the input of the electric driver 1-4, and the output of the Hall sensor 1-5 is connected with the input of the skylight control unit 1-3.
The voice acquisition module 1-1 is used for reducing noise and collecting analog signals of user voice. The voice instruction conversion module 1-2 is used for converting the user voice analog signals collected by the voice acquisition module 1-1 into digital signals and structuring the digital signals. The skylight control unit 1-3 is an actual skylight controller for controlling the skylight to perform various opening and closing actions, and comprises a voice instruction control module 1-3-1 inside. The voice instruction control module 1-3-1 is used for receiving the structural instruction information transmitted by the voice instruction conversion module 1-2 and comparing the structural instruction information with skylight position information stored in the voice instruction control module to feed back an actual actuator driving instruction to the upper skylight control unit 1-3. The motor driver 1-4 is used for executing the actual action of the skylight, and can realize the opening and closing of the skylight through forward and reverse rotation. The Hall sensor 1-5 is used for feeding back the skylight position in the current state in real time to realize the control of the skylight control unit 1-3 on the skylight, and the position information is stored in the voice instruction control module 1-3-1.
The invention provides an intelligent control method based on voice, a skylight control unit can flexibly respond to voice commands, including fine adjustment of raising, fully opening, fully closing, any opening degree or on the basis of any opening degree, and closed-loop control is formed from output to execution, so that the flexibility and the variability of voice control of a skylight are improved, and meanwhile, the skylight control unit does not need to change the original software part due to the increase of the voice commands.
The specific implementation method is as follows: as shown in fig. 2, the voice acquisition module receives a voice analog signal, performs noise reduction on the voice analog signal, and sends the voice analog signal to the voice instruction conversion module, the voice instruction conversion module converts the voice signal into a digital signal for controlling a position command of the skylight, and a signed integer percentage signal is used to represent a position where the skylight is currently required to be executed, wherein 0% is fully closed, 100% is fully opened, 1% is raised, and 2% -99% is the position of other skylights;
boolean signals are used to characterize whether the position signals are relative or absolute, with 0 representing a relative position and 1 representing an absolute position.
In absolute position, the position signal is always positive, while in relative position, the position signal can be positive or negative. The voice instruction conversion module sends the converted skylight position command signal to a voice instruction control module in the skylight control unit, and the voice instruction control module is responsible for storing the position information of the current skylight, receiving the voice instruction signal and feeding back an absolute position signal to an application layer of the skylight control unit.
The voice instruction control module receives a signal sent by the voice instruction conversion module and then judges whether the signal is a relative position signal or an absolute position signal, if the signal is the relative position signal, the voice instruction control module takes out skylight position information stored in the voice instruction control module and adds the skylight position information and the relative position signal to obtain the absolute position signal, whether the absolute position signal is 0% -100% over the range is judged, and if the value is greater than 100%, the absolute position signal is 100%; if the value is less than 0%, the absolute position signal is 0%, and finally the result is fed back to the application layer of the skylight control unit.
If the position signal sent by the voice instruction conversion module is an absolute signal, the voice instruction control module directly feeds back the absolute position signal to the skylight control unit application layer without summing.
Then, the Hall sensor acquires the current actual position information of the skylight, the acquired actual position of the skylight is sent to the skylight control unit, the skylight control unit compares the difference value between the current actual position of the skylight and the position signal fed back by the voice instruction conversion module, whether the difference value is 0 or not is judged, if the difference value is not zero and the difference value is positive, the skylight control unit drives a motor driver, and the skylight is driven to reduce the opening degree; and if the difference value is negative, the skylight control unit drives the motor driver to drive the skylight to be opened to a large opening degree.
Until the skylight is moved to the designated position.
After the task is completed, the skylight control unit feeds back a signal of completing the task to the voice instruction conversion module, and updates the skylight position stored in the voice instruction control module.
The method is characterized in that the signal design of the digital signal converted after the voice input is carried out, the flexibility of skylight control is ensured just due to the design, and meanwhile, the coupling degree with the voice command conversion module is reduced. The voice instruction conversion module can improve the semantic analysis capability of the mobile terminal, can change the arrangement position (in a vehicle and in a cloud), and does not influence the control of the skylight.
Under the precondition of voice input, due to the diversity of voice input, a more compatible signal design is needed to cover a wide variety of possible voice input signals. If the skylight controls a non-voice input, but a key type, the signal design is redundant, because the user can adjust the opening of the skylight by the time length of pressing the key. Speech input is also an important precondition.
Example 1

The voice instruction conversion module sends the converted skylight position command signal to a voice instruction control module in the skylight control unit, the voice instruction control module judges the skylight position command signal as an absolute position signal after receiving the signal sent by the voice instruction conversion module, and the voice instruction control module directly feeds back the absolute position signal to an application layer of the skylight control unit without summing. And then the Hall sensor acquires the current actual position information of the skylight, the acquired actual position of the skylight is sent to the skylight control unit, and the skylight control unit compares the difference value between the current actual position of the skylight and the position signal fed back by the voice instruction conversion module, calculates the difference value to be 99% and is not zero. The skylight control unit drives the motor driver to drive the skylight to reduce the opening degree until the skylight moves to the specified position. After the task is completed, the skylight control unit feeds back a signal of completing the task to the voice instruction conversion module, and updates the skylight position stored in the voice instruction control module 1-3-1 to 1%.
Example 2

The voice instruction conversion module sends the converted skylight position command signal to a voice instruction control module in the skylight control unit, the voice instruction control module judges the skylight position command signal as a relative position signal after receiving the signal sent by the voice instruction conversion module, the voice instruction control module needs to sum skylight current position information stored in the voice instruction control module with the relative position information from the voice instruction conversion module to obtain a value of 102 percent and more than 100 percent, the absolute position signal is updated to be 100 percent, and then the absolute position signal is fed back to an application layer of the skylight control unit. And then the Hall sensor acquires the current actual position information of the skylight, the acquired actual position of the skylight is sent to the skylight control unit, and the skylight control unit compares the difference value between the current actual position of the skylight and the position signal fed back by the voice instruction conversion module, calculates the difference value to be-3% and is not zero. The skylight control unit drives the motor driver to drive the skylight to be opened to a large opening degree until the skylight moves to a specified position. After the task is completed, the skylight control unit feeds back a signal of completing the task to the voice instruction conversion module, and updates the skylight position stored in the voice instruction control module 1-3-1 to 100%.
Example 3
Assuming that the current skylight state is a 3% open state, after receiving a voice command of '20% smaller skylight', the voice acquisition module performs noise reduction on the voice analog signal and sends the voice analog signal to the voice command conversion module, and the voice command conversion module converts the voice signal into a digital signal for controlling the position command of the skylight, wherein the digital signal is a relative position signal with a value of-20%. The voice instruction conversion module sends the converted skylight position command signal to a voice instruction control module in the skylight control unit, the voice instruction control module judges the skylight position command signal as a relative position signal after receiving the signal sent by the voice instruction conversion module, the voice instruction control module needs to sum skylight current position information stored in the voice instruction control module with the relative position information from the voice instruction conversion module to obtain a value of-17%, the absolute position signal is updated to 0%, and the absolute position signal is fed back to an application layer of the skylight control unit. And then the Hall sensor acquires the current actual position information of the skylight, the acquired actual position of the skylight is sent to the skylight control unit, and the skylight control unit compares the difference value between the current actual position of the skylight and the position signal fed back by the voice instruction conversion module, calculates the difference value to be 3% and is not zero. The skylight control unit drives the motor driver to drive the skylight to reduce the opening degree until the skylight moves to the specified position. After the task is completed, the skylight control unit feeds back a signal of completing the task to the voice instruction conversion module, and updates the skylight position stored in the 1-3-1 voice instruction control module to be 0%.
