On the other hand, it adopts an explosion-proof cellular communication hotspot module as a data transmission hub to ensure the effectiveness of data transmission. Furthermore, by sending the harmful gas detection results to the mobile all-angle video monitoring module, the monitoring platform, and the mobile terminal respectively, a multi-device collaborative alarm mechanism is realized, which helps to reduce danger.

[0044] In some embodiments, both the multi-gas detection module and the mobile full-view video monitoring module use the MQTT protocol for data transmission.

[0053] The system provided in this embodiment enhances the reliability of interconnection between devices through dual-mode communication redundancy configuration, ensuring stable data transmission even in complex environments.

[0054] In some embodiments, the mobile multi-gas detection module includes multiple hazardous gas detection units, an alarm decision unit, a first speaker, and a position detection unit. The mobile multi-gas detection module performs real-time detection of hazardous gases within the monitored area and sends the hazardous gas detection results to the mobile full-view video monitoring module, the monitoring platform, and the mobile terminal, respectively, including the following steps:

[0055] For each of the aforementioned hazardous gas detection units, the hazardous gas detection unit detects the gas concentration of its corresponding hazardous gas in real time and sends the gas concentration to the alarm decision unit;

[0056] The alarm decision unit determines whether to activate the first speaker to trigger an alarm based on the gas concentrations sent by each of the harmful gas detection units. It then generates a harmful gas detection result based on the determination result, the gas concentrations corresponding to each of the harmful gas detection units, and the current location information detected by the location detection unit. The harmful gas detection result is then sent to the mobile full-view video monitoring module, the monitoring platform, and the mobile terminal, respectively. Specifically, when the gas concentration corresponding to any harmful gas detection unit is greater than its corresponding gas concentration threshold, it determines to activate the first speaker to trigger an alarm.

[0057] When it is necessary to activate the first speaker to sound an alarm, the alarm decision unit sends an alarm command to the first speaker so that the first speaker sounds an alarm based on the alarm command.

[0058] In this embodiment, when the hazardous gas detection result includes an alarm command, the mobile full-view video monitoring module, upon receiving the hazardous gas detection result, will issue an alarm by flashing the screen and activating the second speaker. When the monitoring platform receives the hazardous gas detection result, it will send alarm information to the terminal device of the monitoring workstation. When the mobile terminal receives the hazardous gas detection result, it will emit an alarm sound to the user of the mobile terminal.

[0059] The system provided in this embodiment, on the one hand, monitors the concentration of different gases in real time through multiple hazardous gas detection units and analyzes them in conjunction with the alarm decision unit, enabling comprehensive detection of hazardous gases and effectively avoiding missed detections. On the other hand, by synchronously sending the hazardous gas detection results to the mobile full-view video monitoring module, monitoring platform, and mobile terminal, a three-level linkage alarm mechanism is formed at the site, monitoring end, and mobile terminal, enhancing the coverage and reliability of hazard warnings. Furthermore, the mobile full-view video monitoring module, monitoring platform, and mobile terminal respectively activate screen flashing, speaker alarm, or information push according to alarm commands, realizing multi-modal alarm collaboration, ensuring that personnel in different scenarios can perceive risks in a timely manner, and comprehensively improving operational safety.

[0060] In some embodiments, the mobile full-view video monitoring module performs real-time panoramic shooting of the monitored area based on the harmful gas detection results, sends the captured images to the monitoring platform, and executes alarm decisions based on the harmful gas detection results, including:

[0061] If the hazardous gas detection result includes an alarm command, the mobile full-view video monitoring module will issue an alarm by flashing the screen and activating the second speaker; wherein, the second speaker is located in the mobile full-view video monitoring module;

[0062] If the harmful gas detection result does not contain an alarm command, the mobile full-view video monitoring module will not trigger an alarm.

[0063] If the harmful gas detection result includes an alarm command, the mobile full-view video monitoring module moves to the location corresponding to the location information, and during the movement, performs real-time panoramic shooting of the monitoring area and sends the captured images to the monitoring platform.

[0064] If the harmful gas detection result does not contain an alarm command, the mobile full-view video monitoring module will not move.

[0065] The system provided in this embodiment has two aspects. First, when the detection result of the harmful gas contains an alarm command, the mobile full-view video monitoring module will issue an alarm by flashing the screen and turning on the second speaker. This dual sound and light warning will quickly alert on-site personnel to the danger and enhance emergency response capabilities. Second, when the detection result of the harmful gas contains an alarm command, the mobile full-view video monitoring module will automatically move to the danger zone and continuously capture panoramic images, providing real-time visual data for the monitoring platform and assisting in remote decision-making.

[0066] In some embodiments, the monitoring platform performs an alarm decision based on the harmful gas detection results and the captured images, including the following steps:

[0067] If the hazardous gas detection result contains an alarm command, the monitoring platform sends an alarm message to the terminal device of the monitoring workstation;

[0068] If the hazardous gas detection result does not contain an alarm command, the monitoring platform determines whether to send an alarm message to the terminal device of the monitoring workstation based on the hazardous gas detection result and the captured image. Specifically, the hazardous gas detection result and the captured image are input into a preset hazardous gas hazard index prediction model to obtain a hazardous gas hazard index. When the hazardous gas hazard index is greater than the preset hazard index, it is determined to send an alarm message to the terminal device of the monitoring workstation. The hazardous gas hazard index prediction model is based on a deep learning multimodal fusion algorithm.

[0069] If so, the monitoring platform sends alarm information to the terminal device of the monitoring workstation.

[0070] The system provided in this embodiment, on the one hand, when the hazardous gas detection result includes an alarm command, the monitoring platform sends alarm information to the terminal device of the monitoring workstation, enabling a rapid response to high-risk situations and shortening the emergency response time; on the other hand, when the hazardous gas detection result does not include an alarm command, a multimodal fusion hazardous gas hazard index prediction model is used, which combines gas data and video images for deep learning analysis, helping to reduce the probability of missed detections and improve the security of the monitored area.

[0071] In some embodiments, the data transmission process of the harmful gas detection system combining video surveillance and odor detection is encrypted based on the TLS / SSL protocol.

[0072] The system provided in this embodiment encrypts transmitted data using the TLS / SSL protocol, effectively ensuring the security and privacy of various data during transmission and preventing data from being stolen or tampered with.
