and finally, controlling the electrically operated gate to move according to the content of the voice instruction after the electrically operated gate receives the RF signal sent by the remote control device through a motion control module.
The operation process of the identification and extraction module comprises the following steps:
firstly, a recognition module is adopted to recognize whether verbs exist in the voice information or not, and if the verbs exist, whether the verbs are verb words preset for commanding the electric door to operate or not is determined, wherein the verb words comprise 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, the locking word acquisition module takes the preset verb word for commanding the electric door to operate as a locking word and marks 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 need to be preset controlled instruction nouns or not; the controlled instruction nouns comprise object nouns and distance words;
and finally, extracting the preset controlled instruction nouns by an extraction module if the words connected after the locked words are the preset controlled instruction nouns.
Wherein, the operation process of the extraction module comprises the following steps:
firstly, judging whether a space word exists between a preset controlled instruction noun and a locking word or not by a space judging module I when the word connected after the locking word is judged to be the preset controlled instruction noun;
then, judging whether the interval words are locking words or words contained in the preset controlled instruction nouns by using an instruction extraction judging module if the interval words exist between the preset controlled instruction nouns and the locking words; if the word is a locked word or a word contained in the preset controlled instruction noun, extracting the preset controlled instruction noun; if the word is not the locked word or the word contained in the preset controlled instruction noun, the preset controlled instruction noun is not extracted, and the remote control device is controlled to carry out voice broadcasting of failure in issuing the control instruction;
then, when no interval word exists between the preset controlled instruction noun and the locking word, judging whether a time interval exists between the preset controlled instruction noun and the locking word through an interval judgment module II; if a time interval does not exist (the locking word and the controlled instruction noun are represented as coherent voice), extracting the preset controlled instruction noun by using a noun extraction module I; when a time interval exists, judging whether the time interval exceeds a preset time interval threshold value or not by using a noun extraction module II, and if the time interval does not exceed the preset time interval threshold value, extracting the preset controlled instruction nouns; and if the time interval existing 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 perform voice broadcast of control instruction assignment failure. Wherein the time interval threshold is set to 4.0s-6.0s, preferably 4.5 s.
The effect of the above technical scheme is as follows: the recognition of the voice command is carried out in the mode, the accuracy of the recognition of the voice command can be effectively improved, meanwhile, when the voice command is interrupted, the recognition of the voice command can be effectively improved, and the problem that the electric door cannot be operated because the voice command cannot be extracted due to the interruption of the voice command is prevented. Meanwhile, effective recognition is carried out on incomplete voice commands or voice commands with long break time, and misoperation of the electric door is prevented. On the other hand, through a voice instruction recognition mode, a plurality of managers can perform voice instruction control near the electric motor, and when voice instruction polyphonic parts are overlapped and superposed to cause the repetition of the voice phonic parts, the voice instruction can be effectively recognized, the voice instruction can be effectively extracted, and the recognition accuracy of the voice instruction is improved. The problem that voice command recognition cannot be effectively carried out due to staggered overlapping of voice parts caused by overlapping of multiple same voice control commands is solved.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
