The working principle of the technical scheme is as follows: the operation process of the control module comprises the following steps:
Firstly, identifying and extracting action words and controlled instruction nouns contained in the voice information by utilizing an identification and extraction module; wherein the action words comprise opening, closing and stopping; the controlled instruction nouns comprise object nouns and distance words, and the distance words comprise: n meters; wherein n is a constant number, n is 0 < n.ltoreq.m is small, and m represents the maximum distance that the electric door can be opened; the object nouns are used to refer to the electrically powered door bodies, e.g., "door", "gate", "electrically powered door", or "electrically powered door", etc.;
then, combining the action words and the distance words through a combination module to form a voice instruction;
then, after a voice instruction is acquired by adopting a signal transmitting module, controlling a remote control device of the electric door to transmit an RF signal to the electric door;
and finally, controlling the electric door to move according to the content of the voice instruction through a movement control module after the electric door receives the RF signal sent by the remote control device.
The operation process of the identification extraction module comprises the following steps:
firstly, adopting a recognition module to recognize whether verbs exist in the voice information, and if the verbs exist, determining whether the verbs are preset verb words for commanding the electric door to operate, for example, words such as open, close, stop or pause;
Then, after recognizing that the preset verb word for commanding the electric door to operate exists in the voice information, using the preset verb word for commanding the electric door to operate as a locking word by a locking word acquisition module, and marking the position of the locking word in the voice information;
then, extracting the words connected after the locking word by adopting an extraction judging module, and judging whether the words connected after the locking word are needed to be the preset controlled instruction nouns or not; wherein the controlled instruction nouns comprise object nouns and distance words;
and finally, extracting the preset controlled instruction noun by an extraction module if the word connected after the locking word is the preset controlled instruction noun.
The operation process of the extraction module comprises the following steps:
firstly, judging whether a spacing word exists between a preset controlled instruction noun and a locking word or not by a spacing judging module when the word connected after judging the locking word is the preset controlled instruction noun;
then, judging whether the spacing word is a locking word or a word or words contained in the preset controlled instruction noun by utilizing an instruction extraction judging module if the spacing word exists between the preset controlled instruction noun and the locking word; if the word is a locking word or a word or word contained in the preset controlled instruction noun, extracting the preset controlled instruction noun; if the word is not a locking word or a word or word contained in the preset controlled instruction noun, the preset controlled instruction noun is not extracted, and the remote control device is controlled to perform voice broadcasting of failure in issuing a control instruction;
Then, judging whether a time interval exists between the preset controlled instruction noun and the locking word or not when no interval word exists between the preset controlled instruction noun and the locking word through an interval judging module II; extracting the preset controlled instruction noun by using a noun extraction module if no time interval exists (the locked word and the controlled instruction noun are represented as coherent voices); when a second time interval exists, judging whether the time interval exceeds a preset time interval threshold, and if the time interval does not exceed the preset time interval threshold, extracting the preset controlled instruction noun; and if the time interval between the preset controlled instruction noun and the locking word exceeds a preset time interval threshold value, the noun extraction module III does not extract the preset controlled instruction noun and controls the remote control device to carry out voice broadcasting of failure in issuing a control instruction. Wherein the time interval threshold is set to 4.0s-6.0s, preferably 4.5s.
The technical scheme has the effects that: through the mode, the voice command recognition can be effectively improved, meanwhile, when the voice command is in a discontinuous condition, the voice command recognition can be effectively improved, and the problem that the electric door cannot be operated due to the fact that the voice command cannot be extracted due to the fact that the voice command is discontinuous is solved. Meanwhile, the method and the device can effectively identify incomplete voice instructions or voice instructions with longer break time, and prevent misoperation of the electric door. On the other hand, through the voice command recognition mode, a plurality of management personnel can exist near the electric machine to control the voice command, and when the voice command multiple sound parts are overlapped and overlapped to cause the repetition of the voice sound parts, the voice command can be effectively recognized, the voice command can be effectively extracted, and the recognition accuracy of the voice command is improved. The problem that voice command recognition cannot be effectively performed due to staggered and overlapped voice parts caused by overlapping of multiple identical voice control commands is prevented.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
