Description

Technical Field

[0001] This utility model relates to security monitoring technology for public facilities. Background Technology

[0002] Public facilities, especially those located at high altitudes, such as rooftop light box advertisements, are exposed to wind and sun, resulting in wind damage and component aging, which can lead to safety hazards related to structural strength, electrical leakage, fire prevention, and electrical overload. It is well known that component aging weakens structural strength; after prolonged use, the components and the structures they form no longer possess the designed strength, inevitably leading to breakage or deformation under strong winds. If the insulation of electrical equipment ages, is damaged, or becomes damp, it can cause current leakage. While minor leakage may only result in wasted electricity, severe leakage can cause electric shock to personnel handling the equipment, leading to injury or death. Overload operation, short circuits, or leakage can all generate electrical sparks, potentially causing fires. Many electrical fires are caused by prolonged abnormal operation of circuits or equipment. If electrical equipment is under overload for extended periods, it accelerates aging, shortens its lifespan, and can also cause overheating, insulation damage, and even electrical fires. However, current technology lacks the means to monitor these safety hazards in public facilities. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to monitor public facilities through a communication network, thereby obtaining a public facility safety monitoring system.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: The public facility safety monitoring system includes a hazard monitor, a power supply line switching device, and a hazard processing server. The hazard monitor includes a housing I, and within the housing I are a control unit I, a power supply unit I, a network communication module I, a storage module, a positioning module, a photoelectric output module, an acceleration sensor module, an angle sensor module, a temperature sensor module, and a camera module, as well as a leakage current sensing module located outside the housing I. The power supply unit I, network communication module I, storage module, positioning module, photoelectric output module, acceleration sensor module, angle sensor module, temperature sensor module, leakage current sensing module, and camera module are all connected to and controlled by the control unit I. The control unit I, network communication module I, storage module, positioning module, photoelectric output module, acceleration sensor module, angle sensor module, temperature sensor module, leakage current sensing module, and camera module are all connected to the power supply unit I and powered by the power supply unit I. The hazard monitor communicates with the hazard processing server through the network communication module I. The storage module has a corresponding ground... The system includes information such as address, recipient information for receiving emergencies, warning content, and detection data. The positioning module provides the real-time location of the emergency monitor. The photoelectric output module emits warning content photoelectrically. The acceleration sensor module measures the acceleration of the emergency monitor. The angle sensor module measures the tilt angle of the emergency monitor. The temperature sensor module measures the temperature of the environment surrounding the emergency monitor. The leakage current sensor module monitors leakage in the power supply line. The camera module captures real-time video of the environment around the emergency monitor. The power supply line switching device includes a housing II, and within the housing II are a control unit II, a power supply unit II, a network communication module II, and a switch module. The power supply unit II, network communication module II, and switch module are all connected to and controlled by the control unit II. The control unit II, network communication module II, and switch module are all connected to and powered by the power supply unit II. The power supply line switching device communicates with the emergency handling server through the network communication module II. The switch module controls the connection or disconnection of the power supply line for the electrical equipment.

[0005] This technical solution monitors electrical equipment to detect leakage current in real time. Once the leakage current exceeds a safe threshold, the system can issue an alarm promptly and automatically cut off the power supply circuit, thereby protecting the normal operation of the equipment, extending its service life, and reducing various safety risks caused by overload, especially preventing electric shock. By monitoring the temperature of the hazard monitor itself, the system can issue an early warning when an abnormal temperature increase is detected due to overload or fire, reminding personnel to take action. Potential hazards can also be identified by the acceleration caused by impact and the tilting and rotation angle obtained from changes in the monitor's spatial posture.

[0006] To obtain a larger on-site warning area, the photoelectric output module is equipped with a warning light and a speaker, the camera module is equipped with a camera, the detection parts of the camera and the temperature sensing module are located on the same side of the housing, and the speaker and warning light are distributed on the edge of the housing.

[0007] To facilitate the installation of the hazard monitoring device and enable it to shut down during the storage phase and remain in standby mode during the usage phase, the power supply unit I is equipped with a switch button located at the bottom of the housing I. The bottom of the housing I is also equipped with an interface for connecting to the leakage current sensing module.

[0008] To improve the efficiency and performance of public facility security monitoring systems, this utility model also provides a method for reporting hazards based on such systems. The method is detailed below.

[0009] The first step is to initialize the hazard monitor, configuring it with information corresponding to the address, recipient information for receiving hazard alerts, and warning content. This includes setting the image trigger threshold (ITC), acceleration trigger threshold (ASTC), angle trigger threshold (ATC), temperature trigger threshold (TTC), and leakage current intensity trigger threshold (ETC).

[0010] Set the image trigger threshold (ITD), acceleration trigger threshold (ASTD), angle trigger threshold (ATD), temperature trigger threshold (TTD), and leakage current intensity trigger threshold (ETD).

[0011] The second step involves the hazard monitor sending one or more of the following trigger conditions to the hazard handling server: ITC (Information Technology Control), ASTC (Acceleration Trigger Threshold), ATC (Angle Trigger Threshold), TTC (Temperature Trigger Threshold), and ETC (Leakage Current Intensity Trigger Threshold). These conditions include the presence of open flames and / or dense smoke in the video, triggering an acceleration greater than the ASTC threshold, triggering an acceleration greater than the ASTC threshold, triggering an angle greater than the ATC threshold, triggering an angle greater than the ATC threshold, triggering a temperature greater than the ETC threshold, and triggering a leakage current greater than the ETC threshold. Simultaneously, the hazard monitor issues a warning message.

[0012] The third step involves the hazard handling server reporting hazard warning information, including at least the real-time location and corresponding address, based on the recipient's information.

[0013] Fourth, when the video contains open flames and / or dense smoke, matching one or more of the following five trigger conditions: ITD (Information Technology Determination), ASTD (Acceleration Trigger Threshold), ATD (Angle Trigger Threshold), TTD (Temperature Trigger Threshold), and ETD (Current Intensity Trigger Threshold), the hazard monitor sends its real-time location, recipient information of the hazard, and one or more abnormal data points corresponding to the trigger condition (real-time environmental video, detected acceleration, detected angle, detected temperature, and detected current) to the hazard processing server. Simultaneously, the hazard monitor issues a warning, and the hazard processing server sends a command to the power supply line switching device to disconnect the power supply line, causing the device to disconnect the power supply line.

[0014] The fifth step involves the hazard handling server reporting hazard warning information, including at least the real-time location and the corresponding address, based on the recipient's information.

[0015] The hazard monitor has at least two recipients' information for receiving hazard information, and the hazard processing server reports hazard warning information based on all recipients' information. The hazard processing server can access video data from any hazard monitor. The hazard processing server issues a command to the power line switching device to connect the power line, causing the power line switching device to establish a connection on the power line.

[0016] This utility model adopts the above-mentioned technical solution: the public facility safety monitoring system obtains a variety of parameters through monitoring, judges whether a danger has occurred based on the parameters, can issue early warnings to personnel in the early stage of a danger, and provide a location indication of the danger, so as to take accurate and effective measures to deal with the danger in a timely manner.

[0022] like Figure 1 ,2 As shown in Figures 3 and 4, the public facility safety monitoring system includes a hazard monitor, a power line switching device, and a hazard handling server. The public facility safety monitoring system adopts a centralized control mode, with the hazard handling server as the control center, the hazard monitor as the input, and the power line switching device as the output.

[0023] The hazard monitoring device includes a housing I1, and within the housing I1 are a control unit I2, a power supply unit I3, a network communication module I4, a storage module 5, a positioning module 6, a photoelectric output module 7, an acceleration sensor module 8, an angle sensor module 9, a temperature sensor module 10, and a camera module 11, as well as a leakage current sensing module 12 located outside the housing I1. The power supply unit I3, network communication module I4, storage module 5, positioning module 6, photoelectric output module 7, acceleration sensor module 8, angle sensor module 9, temperature sensor module 10, leakage current sensing module 12, and camera module 11 are all connected to and controlled by the control unit I2. Control unit I2, network communication module I4, storage module 5, positioning module 6, photoelectric output module 7, acceleration sensor module 8, angle sensor module 9, temperature sensor module 10, leakage current sensing module 12, and camera module 11 are all connected to power supply unit I3 and are powered by power supply unit I3. Power supply unit I3 is equipped with a switch button 20, which can be used to put the hazard monitor into a power-on or power-off state. The hazard monitor communicates with the hazard processing server through network communication module I4. Storage module 5 contains information corresponding to the address, recipient information of the hazard, warning content, and detected data. Positioning module 6 is used to provide the real-time location of the hazard monitor. Photoelectric output module 7 is equipped with a warning light 17 and a speaker 18, and is used to emit warning content photoelectrically. Acceleration sensor module 8 is used to measure the acceleration of the hazard monitor. Angle sensor module 9 is used to measure the tilt and rotation angle of the hazard monitor. Temperature sensor module 10 is used to measure the temperature of the environment around the hazard monitor. The leakage current sensing module 12 is used to monitor leakage current in the power supply line. The camera module 11 is equipped with a camera 19, which is used to capture real-time environmental video around the hazard monitoring device.

[0024] The power supply line switching device includes a housing II, and within the housing II are a control unit II 13, a power supply unit II 14, a network communication module II 15, and a switch module 16. All three units are connected to and controlled by the control unit II 13. The control unit II 13, network communication module II 15, and switch module 16 are all connected to and powered by the power supply unit II 14. The power supply line switching device communicates with the emergency response server via the network communication module II 15. The switch module 16 controls the connection or disconnection of the power supply line to the electrical equipment. In use, the power supply line switching device is connected to the power supply line of the electrical equipment.

[0025] The detection points of the camera 19 and the temperature sensing module 9 are both located on the same side of the housing, while the speaker 18 and the warning light 17 are distributed along the edge of the housing. The switch button 20 is located at the bottom of the housing I1. The bottom of the housing I1 also has an interface for connecting to the leakage current sensing module 12, and the leakage current sensing module 12 is connected to the control unit I2 via a plug-in connection.

[0026] Before operation, the hazard monitor is placed in the area where the public facilities (i.e., the electrical equipment) are located. The leakage current sensing module 12 and the switch module 16 are connected to the power supply line of the electrical equipment to monitor it. First, the hazard monitor is initialized by configuring the address information, the recipient information for receiving hazard alerts, and the warning content. The image trigger content (ITC) and the acceleration trigger threshold (ASTC) are set to 20 m / s². 2 The angle trigger threshold (ATC) is set to 3 degrees, the temperature trigger threshold (TTC) to 90 degrees Celsius, and the leakage current intensity trigger threshold (ETC) to 0.1 mA; the image trigger content (ITD) and acceleration trigger threshold (ASTD) are set to 50 m / s². 2 The angle trigger threshold (ATD) is 6 degrees, the temperature trigger threshold (TTD) is 150 degrees Celsius, and the leakage current intensity trigger threshold (ETD) is 1mA. The address information refers to the location of the hazard monitor. The values ​​of acceleration, angle, temperature, and current recorded here will be adjusted according to the actual operating conditions, and therefore the values ​​will differ in other embodiments.

[0027] During operation, when one or more of the following five trigger conditions occur: video containing open flames and / or dense smoke (ITC), acceleration exceeding the acceleration trigger threshold (ASTC), angle exceeding the angle trigger threshold (ATC), temperature exceeding the temperature trigger threshold (TTC), and current exceeding the leakage current intensity trigger threshold (ETC), the hazard monitor sends its real-time location, recipient information for the hazard, and one or more abnormal data points corresponding to the trigger condition, including real-time environmental video, detected acceleration, detected angle, detected temperature, and detected current, to the hazard processing server. Simultaneously, the hazard monitor issues a warning. The hazard processing server then reports a hazard warning message, including at least the real-time location and corresponding address information, based on the recipient information. The hazard monitor can be configured with two or more recipient information points; the hazard processing server reports the hazard warning message based on all recipient information points.

[0028] Image-triggered content (ITD) also includes open flame or smoke, or both, but compared to open flame or smoke in image-triggered content (ITC), open flame or smoke in image-triggered content (ITD) appears to be more intense.

[0029] After the above situation occurs, if the video contains a stronger open flame and / or dense smoke that meets one or more of the following five trigger conditions: ITD (Information Technology Determination), ASTD (Acceleration Trigger Threshold), ATD (Angle Trigger Threshold), TTD (Temperature Trigger Threshold), and ETD (Current Intensity Trigger Threshold), the hazard monitor sends its real-time location, recipient information of the hazard, and one or more abnormal data points corresponding to the trigger condition, such as real-time environmental video, detected acceleration, detected angle, detected temperature, and detected current, to the hazard processing server. Simultaneously, the hazard monitor issues a warning, and the hazard processing server sends a command to the power line switching device to disconnect the power line, causing the device to disconnect from the power line. Then, the hazard processing server reports a hazard warning message, including at least the real-time location and corresponding address information, based on the recipient information. The hazard monitor can be configured with two or more recipients for receiving hazard information, and the hazard processing server reports the hazard warning message based on all recipient information.

[0030] Therefore, the settings for image trigger content ITC, acceleration trigger threshold ASTC, angle trigger threshold ATC, temperature trigger threshold TTC, and leakage current intensity trigger threshold ETC are consistent with the initial state of a hazard; while the settings for image trigger content ITD, acceleration trigger threshold ASTD, angle trigger threshold ATD, temperature trigger threshold TTD, and leakage current intensity trigger threshold ETD are consistent with the trend of a hazard developing into a more severe state. These initialization settings are based on operating conditions, and generally, the values ​​of the first group of parameters are smaller than the values ​​of the second group of parameters.

[0031] The hazard monitor contains information on at least two recipients of the hazard notification. The hazard processing server sends hazard warning information based on all the recipient information.

[0032] During communication between the hazard monitor and the hazard handling server, the hazard handling server can access video data from any hazard monitor. When the hazard handling server issues a command to the power line switching device to connect the power line, it can cause the power line switching device to form a connection on the power line, so that the electrical equipment monitored by the hazard monitor on the power line can be controlled.
