[0039] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0040] Please refer to Figs. 1-3 The application provides a technical solution:

[0041] An intelligent sensing communication control device, comprising

[0042] A plurality of sensor unit modules: for installation in corresponding positions and collecting corresponding information of the positions and establishing the collected data information as a database, the sensor unit modules including a series of sensors for devices, environments and different scenes and objects, such as motion sensors, temperature sensors, pressure sensors, etc., through different functional sensors, corresponding data can be obtained, the obtained data is used to reflect the actual situation, and the measured data is collected to form a database;

[0043] A preprocessing module: converting the data in the database into digital signals and preprocessing the collected digital signals, including denoising, filtering, and normalization, the denoising method is to take the average value of the local area of the signal to reduce random noise, replace the value of each point with the intermediate value, which is particularly effective for impulse noise and salt and pepper noise, use the mean filter with Gaussian function as the weight to smooth the signal, and decompose the signal into different frequencies through wavelet transform, then remove the high-frequency noise component in the wavelet domain, and the filtering method is to realize through the installation of low-pass filter, high-pass filter, band-pass filter, and band-stop filter, in addition, during normalization, the existing technologies such as minimum-maximum normalization, Z-score normalization and decimal scaling normalization can be referred to;

[0044] A signal sending module: outputting the processed digital signals, such as through an antenna, Bluetooth or using a network cable to realize signal output;

[0045] A receiving module: provided with two signal input ends, one of which is connected with the signal sending module for receiving the processed digital signals, and the other is connected with the control signal input module for receiving the control signals;

[0046] A sensor unit signal analysis module: analyzing the digital signals of the sensor unit module received in the receiving module, judging what measures should be taken according to the analysis results, selecting the input control signals according to the judged measures, in actual use, for example, when the pressure sensor monitors that the pressure in a certain gas tank is too high and has an explosion risk, the input control signal is used to drive the pressure relief valve connected with the gas tank to open or stop inflating the gas tank, so as to reduce the gas pressure in the gas tank;

[0047] A recovery module: for converting the input control signal from digital signal to text signal after processing, different control platforms have different input methods, if the input signal is in analog form, such as sound signal, the signal is voice, the signal is in coded form or non-voice signal, such as telegraph signal or Morse code, it needs to be simply converted into digital signal first, and then converted into text signal through digital signal, so as to facilitate personnel to extract the key words in the text signal;

[0048] The control signal analysis module analyzes the input control signal, analyzes the words of the input control signal, judges whether the words conform to the daily habits of the operator, and outputs to the corresponding device after recording the input time and the account information of the inputter if the words conform to the daily habits of the operator, and issues a warning if the words do not conform or the degree of conformity is not high. In actual use, for example, the control signal may be "open the power supply switch, the power supply module sends power to the motor, and drives the motor to run" when the actual operator edits the control signal and converts it into a text signal, while the normal and conventional text signal may be "send power to the motor and start the motor" when the motor needs to be controlled. Therefore, when the motor needs to be controlled, it is only necessary to judge whether the input text information conforms to the habits of the actual operator to determine whether the person inputting the control signal is the actual operator.

[0049] Further, the input end of the control signal input module is connected with the signal sending module, and the signal sending module is connected with the preprocessing module. The input control text signal is converted into a digital signal by the preprocessing module and then input into the control signal input module through the signal sending module.

[0050] Further, the recovery module comprises:

[0051] The signal decoding and analysis module decodes the processed input control signal and analyzes the signal to determine its type and structure. Before signal decoding, the signal is preprocessed, including smoothing and denoising, which can remove noise and outliers in the signal by using methods such as moving average filter, median filter, Hampel filter, etc. According to the different categories of input control signals, when the input control signal is an analog signal, the continuous analog signal is first converted into a discrete-time signal for sampling, and then the sampled value is converted into a digital form. When the input control signal is a digital signal, the receiver and the transmitter are first synchronized to correctly decode the signal, and then demodulation is performed according to the modulation method of the signal (such as AM, FM, PM or digital modulation technology). When the input control signal is a voice signal, the voice signal can be converted into text or commands. When the input control signal is an image and video signal, the original image or video stream is first compressed using JPEG, MPEG, etc., and then recovered using the corresponding decoding algorithm.

[0052] The signal processing module uses digital signal processing techniques such as filtering, Fourier transform, etc. to improve signal quality or extract useful information, converts the processed signal into a format suitable for text representation, uses Fourier transform to convert the signal from time domain to frequency domain, analyzes the frequency components of the signal, and then designs a filter to remove unwanted frequency components.

[0053] Furthermore, the control signal analysis module includes:

[0054] The password library module is divided into three areas: a general term library, a special term library, and a newly added term library. The general term library stores common control terms, the special term library stores user-defined control terms, and the newly added term library stores terms not found in the general or special term libraries in the text generated by the signal processing module. In actual use, the general term library might contain terms like "open," "close," "rotate XX degrees," "open valve," or "close valve," for example, a sluice gate valve rising 50cm and remaining open for 30 minutes. The special term library is for user-defined terms, such as "immediately," "quickly," or "maintain time," for example, immediately raising the sluice gate valve 50cm and maintaining its open position for 30 minutes. The newly added term library temporarily stores newly encountered terms, allowing users to choose whether to retain them. If retained, they are automatically moved to the special term library. For example, if the drive system starts and controls the sluice gate valve to rise vertically 50cm for 30 minutes, the newly added terms would be "raise," "set time."

[0055] Overlap Comparison Module: This module extracts words from the text generated by the signal processing module and compares the extracted words with words stored in the general vocabulary library and the special vocabulary library. If some of the words in the text generated by the signal processing module match words in the general vocabulary library and others match words stored in the special vocabulary library, it means that the input control signal was entered by the operator.

[0056] If some of the words in the text generated by the signal processing module match the words in the regular vocabulary library, and some of the words in another part match the words stored in the special vocabulary library, that is, the overlap is low, then the words in the other part of the text generated by the signal processing module that do not match the words in the special vocabulary library will be stored in the newly added vocabulary library.

[0057] For example, if the input control signal is: "At 9:50 AM tomorrow, sluice gate valve No. 1 will be raised 50cm quickly to drain water and relieve pressure, and the valve will be open for 30 minutes," then the actual input control signal fully mentions "quickly" and "for 30 minutes" from the special terminology library, indicating a high degree of overlap. This means the operator inputting the control signal is the actual operator. Conversely, if the text signal of the input control signal does not use words from the special terminology library, it means the input control signal is from someone else. In this case, the newly appearing words in the control signal will be temporarily collected in the newly added terminology library.

[0058] Early warning module: This module bypasses the login account and directly contacts the control system owner. It sends the login account for the input control signal and the wording from the extracted signal processing module's generated text directly to the owner via network communication (telephone or SMS). When an anomaly in the input control signal is detected, it directly contacts the operator, ensuring the operator can directly access the text command and account information of the input control signal. The operator can then determine the validity of the abnormal control signal—whether it was entered by an unauthorized person or with the operator's permission—thus ensuring safety.

[0059] Furthermore: The early warning module includes:

[0060] Signal source recording module: used to record account information, user's face, and fingerprint login information of the login control system. By installing a facial unlocking system, fingerprint system, and account login system, the three work together to allow others to log in to the control device after stealing someone else's account, and then send out incorrect control signals.

[0061] Signal source locking module: used to freeze the login user's account the moment the warning module issues a warning, and to upload the information recorded by the signal source recording module to the cloud and the control system owner.

[0062] Furthermore: also includes:

[0063] Connection port module: Used to connect several sensor unit modules to external devices, including gateway interface, charging interface, video interface, speaker and microphone interface, device interface, etc.;

[0064] Power supply module: There are two power supply modules. One power supply module is used to power several sensor unit modules, preprocessing module, signal transmission module, receiving module, and connection port module. The other power supply module is used to independently power the recovery module and control signal analysis module.

[0065] Switching module: Used to connect the recovery module and the receiving module when there is a control signal input, and to disconnect the recovery module and the receiving module when processing the input control signal.

[0066] Furthermore, the control signal analysis module employs NLP technology to analyze the extracted text, including word segmentation, part-of-speech tagging, named entity recognition, and dependency parsing, in order to understand the structure and meaning of the text.

[0067] The device's operation and working principle are as follows: When the sensor module detects an anomaly, the abnormal data is sent to the receiving module via the preprocessing module and signal transmission module. The sensor unit signal analysis module then analyzes the received sensor module signal to determine the appropriate processing and control signal input. The operator inputs the corresponding control command based on the analysis results. This input control command is processed into a digital signal by the preprocessing module and then sent to the receiving module via the signal transmission module. The recovery module performs secondary processing on the input control signal to obtain a text signal. After parsing and processing by the signal decoding and analysis module and the signal processing module, the keywords of the text signal are obtained. The overlap comparison module analyzes the overlap between the obtained keywords and words in the general and special word libraries to determine the source of the command. If the signal is extracted... If the text generated by the signal processing module contains words that partially match the terms in the general terminology library and partially match the terms in the special terminology library, it indicates that the input control signal was entered by the operator. In this case, the control signal received by the receiving module can be directly output to the corresponding device. If the text generated by the signal processing module contains words that partially match the terms in the general terminology library and partially match the terms in the special terminology library (i.e., the overlap is low), then the words in the other part of the text generated by the signal processing module that do not match the terms in the special terminology library are stored in the new terminology library. The warning module then directly notifies the operator, ensuring that the operator can directly obtain the text command and account information of the input control signal. The operator can then determine the correctness of the abnormal control signal, i.e., whether it was entered by an unrelated person or with the operator's permission, thus ensuring safety.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
