[0022] The user information collection module 106 is used to identify the identity information of the user of the LED display screen and collect the usage habit information of the user of the LED display screen. The user usage model establishment module 107 builds a personalized usage habit model based on the user's historical viewing records and behavior patterns to provide intelligent support for content recommendation and time management. The parameter adjustment module 108 is used to automatically adjust the parameters of the LED display screen according to user preferences and usage scenarios.

[0023] In this embodiment, the identity recognition module 103 ensures that only authorized users can access the control system to enhance security. The remote control module 104 authorizes users to remotely control the LED display screen through mobile devices. The remote control module 104 monitors the viewing content and duration of users of the LED display screen in real time, and sends a reminder message to the guardian of the remote control terminal 101 when the viewing content and duration reach a threshold. The user information collection module 106 identifies the identity information of the user of the LED display screen, and collects the usage habit information of the user of the LED display screen.

The parameter adjustment module 108 is used to automatically adjust the parameters of the LED display screen according to user preferences and usage scenarios. The present technical solution can effectively supervise the viewing content and time of specific user groups such as children and students to avoid exposure to bad information and excessive entertainment.

[0024] Furthermore, the identity recognition module 103 includes a data entry submodule 109, a data preprocessing submodule 110, a feature matching submodule 111, a decision submodule 112 and a database management submodule 113. The data entry submodule 109 is used to collect the user's biometric data or input identity authentication information, the data preprocessing submodule 110 is used to preprocess the collected raw data to improve the accuracy and efficiency of the subsequent recognition algorithm, the feature matching submodule 111 is used to match the preprocessed features with the features stored in the database to verify the user's identity, the decision submodule 112 is used to decide whether to allow the user to access the control system based on the result of feature matching, and the database management submodule 113 is used to store and manage the user's biometric data or identity authentication information, as well as related metadata.

[0025] In this embodiment, the identity recognition module 103 involves a fingerprint recognition algorithm, a face recognition algorithm and a password verification algorithm.

[0026] Among them, the specific steps of the fingerprint recognition algorithm are:

[0027] Collect fingerprint images;

[0028] Preprocess the fingerprint image, including denoising, contrast enhancement, binarization, etc.;

[0029] Extract fingerprint features, such as endpoints, bifurcation points, ridge directions, etc.;

[0030] Match the extracted features with those in the database.

[0031] Preferred: In the process of feature extraction and matching, image processing formulas are involved, such as grayscale stretching formula, binarization threshold formula, etc. In addition, distance calculation formulas may be used to evaluate the similarity between two fingerprint features during feature matching.

[0032] Among them, the specific steps of the facial recognition algorithm are:

[0033] Collecting facial images;

[0034] Preprocess facial images, including denoising, grayscale, histogram equalization, etc.;

[0035] Detect facial key points such as eyes, nose, mouth, etc.;

[0036] Extract facial features, such as facial texture, shape, etc.;

[0037] Match the extracted features with those in the database.

[0038] Preferred: In the process of feature extraction and matching, formulas in the fields of image processing, machine learning, etc. are involved. For example, in facial key point detection, algorithms such as Hough transform or active shape model may be used; in feature extraction, algorithms such as local binary pattern (LBP) or scale-invariant feature transform (SIFT) may be used; in feature matching, formulas such as cosine similarity or Euclidean distance may be used to evaluate the similarity between two facial features.

[0039] Among them, the specific steps of the password verification algorithm are:

[0040] User enters password;

[0041] Compare the entered password with the passwords in the database.

[0042] Preferably, in the password verification process, in order to ensure the security of the password, a hash algorithm may be used to encrypt, store and compare the password. The hash algorithm converts the password into a hash value of fixed length, so that even if the original password is leaked, the original password cannot be directly deduced from the hash value. The security of the hash algorithm depends on its anti-collision and unidirectional properties.

[0043] Furthermore, the remote monitoring module 105 includes a content monitoring submodule 114, a time management submodule 115 and an emergency intervention submodule 116. The content monitoring submodule 114 is used to monitor the content played on the LED display screen in real time, identify and mark content that is not suitable for children or students, and the time management submodule 115 is used to set and monitor the daily viewing time limit to ensure that users arrange their rest time reasonably and avoid excessive use. The emergency intervention submodule 116 is used to immediately send an emergency notification to the remote control terminal 101 when serious illegal content or user health risks are detected, allowing guardians to take quick measures.

[0044] Furthermore, the usage habit information of the user of the LED display screen collected by the user information collection module 106 includes the brightness, contrast and color temperature of the LED display screen.

[0045] Among them, the user usage model establishment module 107 includes a data cleaning submodule 117, a feature extraction submodule 118, a model training submodule 119 and a model optimization submodule 120. The data cleaning submodule 117 is used to clean, organize and normalize the usage habit information collected by the user information collection module 106. The feature extraction submodule 118 is used to extract features that are valuable for user behavior modeling from the preprocessed data. The model training submodule 119 is used to train the user behavior model using the extracted feature data.
