[0038] like Figure 1 As shown, the present invention provides a campus restroom bullying warning method, comprising:

[0039] S101, collect real-time audio data in the restroom and send it to the first device. The audio data is used by the first device to perform data analysis based on a large model, generate alarm information and send it to the second device. The alarm information is used by the second device to perform synchronous early warning of multiple devices.

[0040] S102: Perform synchronous warning based on the received alarm information of the second device. It is worth emphasizing that the first device and the second device can be two independent devices or the same device.

[0041] In some embodiments, in order to achieve automatic judgment and intervention of bullying behavior, data analysis is performed based on a large model to generate alarm information, including: converting the audio data into text information based on speech recognition technology, and performing semantic analysis and understanding based on generative artificial intelligence of a large language model to generate alarm information.

[0042] In some specific embodiments, in order to improve the accuracy of audio-to-text conversion, the speech recognition technology is based on the iFlytek conversion model.

[0043] In other specific embodiments, in order to identify emotions to assist in judging possible bullying behaviors, further reduce false alarms, and improve the accuracy of early warnings, the large language model is based on a transformer model, and / or is assisted by a speech emotion recognition module (such as emotion2vec).

[0044] In some embodiments, in order to protect student privacy while ensuring correct alarm, when the audio data is determined to be risk-free by the first device, it will be overwritten by subsequent audio data, the current audio data will not be archived, and the corresponding text will be stored in a buffer that is cleared regularly.

[0045] In some embodiments, in order to facilitate the on-duty teacher of the security center to respond immediately and arrive at the scene in time to handle the problem, the synchronous warning of multiple devices includes: synchronous warning of the first device, the second device and the third device, and the third device is the teacher terminal.

[0046] Figure 2As shown, based on the above-mentioned campus restroom bullying warning method, the present invention provides a campus restroom bullying warning system 200, including a terminal device 201, a first device 202 and a second device 203; the terminal device 201 is connected to the first device 202, and the second device 203 is connected to the first device 202 and the second device 203 respectively; the terminal device is used to collect audio data in the restroom and send it to the first device 202; the first device 202 is used to perform data analysis on the audio data based on a large model, generate alarm information and send it to the second device 203; the second device 203 is used to perform synchronous warning of multiple devices based on the alarm information. Among them, the terminal device 201 and the first device 202, and the first device 202 and the second device 203 can be connected by wire or by wireless.

[0047] In some embodiments, in order to stop bullying behavior promptly and quickly, the terminal device 201 includes an electrically connected controller, a microphone, an alarm button, an alarm light and a buzzer. When the alarm is triggered, the warning light in the restroom will immediately light up and a buzzer alarm will sound to deter the bully.

[0048] In some embodiments, in order to alleviate the problem of false alarms, the system also includes an alarm button installed on the outside of the restroom, which is connected to the first device and is located within the coverage of the video surveillance. This not only allows other students to intervene in time and safely report bullying behavior when they discover it, but also effectively prevents the occurrence of false alarms or random reports.

[0049] In some embodiments, in order to save resources, the system also includes a smart sensor, which is used to detect whether there is someone in the restroom. If no one is in the restroom, the system enters a standby state to save computing power and electricity consumption.

[0050] For ease of understanding, this embodiment further describes the specific implementation process of the above system in conjunction with a specific application scenario system. Figure 4 and Figure 5 As shown, in this embodiment, the terminal device 201 is a frontier terminal, the first device 202 is a processing terminal, and the second device 203 is a cloud server. Its functional characteristics and working principles are as follows:

[0051] 1. Frontier Terminal: Installed in the campus restroom, it is based on the ESP32 controller and includes an alarm button, LED alarm light, buzzer and microphone. It is responsible for collecting audio and sending it to the processing end for analysis, while controlling the alarm button and alarm device.

[0052] 2. Processing end: Installed in the campus security center, it connects the speech-to-text model and the generative artificial intelligence for semantic understanding, and is responsible for data processing and analysis. The speech-to-text conversion here uses the interface of iFlytek, and the semantic understanding is connected to Baidu's Wenxin intelligent body and simulated using a laptop computer.

[0053] 3. Cloud server: responsible for the exchange of alarm information.

[0054] 1. Speech recognition and semantic analysis: The system uses speech recognition technology to convert the conversation content in the restroom into text information, and uses generative artificial intelligence to perform semantic analysis and understanding, to achieve rapid identification and intelligent judgment of bullying behavior, thereby improving the level of campus safety management.

[0055] 2. Alarm prompts and timely intervention: When the system detects possible bullying behavior, it will automatically issue an alarm prompt and notify the responsible teacher of the alarm information as soon as possible so that they can quickly arrive at the scene to deal with it and stop school bullying in time.

[0056] 3. Emergency alarm mechanism: When students encounter bullying, they or others can press the emergency alarm button inside or outside the restroom to quickly start the alarm process. When someone presses the button, the LED in the restroom will immediately light up and the alarm will sound. At the same time, the teacher in charge will be notified, which will deter the bully in the first place and reduce the harm to the bullied.

[0057] The key points of the embodiments of the present invention are as follows:

[0058] 1. Considering that it is impossible to set up video surveillance in the restroom, the system uses voice recognition and large language models to confirm the internal situation of the restroom through real-time monitoring, and processes audio information instantly without archiving it to protect privacy.

[0059] 2. In order to improve the accuracy of the system in identifying bullying behaviors, the project uses generative artificial intelligence based on a large language model for identification. Unlike traditional keyword recognition technology solutions, it can perform semantic analysis on the content of the conversation, understand the content of the conversation and judge the possible risk of bullying, just like a human listener. At the same time, as an artificial intelligence, it does not have the privacy issues that human listeners usually have. In terms of specific implementation, the Wenxin intelligent agent based on Baidu Wenxin Big Model 4.0 is used for interpretation. The basic model is trained and open to use by Baidu, and is called through the relevant interfaces provided by Baidu. At the same time, the comprehensive performance of the model is optimized through the accumulated training records during the knowledge base mounting test. Through the core technology of generative artificial intelligence, the recognition of most bullying behaviors involving violent language is realized, and the comprehensive performance is significantly better than the keyword recognition technology solution.

[0060] At the same time, in order to ensure direct and effective assistance in emergency situations, in addition to the fully automated monitoring system, the system also has a manual alarm system that can be manually operated. Emergency alarm buttons are installed inside and outside the toilet, and the alarm process can be quickly activated with one button.

[0061] 3. In order to stop bullying in a timely and rapid manner, when the alarm is triggered, the warning light in the restroom will immediately light up and the buzzer alarm will sound to deter the bully. At the same time, the campus security center and all terminal devices equipped with the system will also receive the alarm information synchronously, so that the teacher on duty at the security center can respond immediately and arrive at the scene to handle it in time.

[0062] 4. To alleviate the problem of false alarms, when an alarm is sounded, teachers on duty at the campus security center can use the broadcasting system to listen to the sound directly to confirm the situation, and can use the system terminal to communicate with people in the restroom to confirm the situation inside the restroom and manually determine whether there is bullying. At the same time, the alarm button outside the restroom is within the coverage of video surveillance, which not only allows other students to intervene in time and safely report bullying when they find bullying, but also effectively suppresses the occurrence of false alarms or random reports.

[0063] 5. To save resources, the system is also equipped with intelligent sensors to determine whether there is someone in the bathroom. If no one is in the bathroom, the system will enter standby mode, saving computing power and electricity consumption.
