Description

Technical Field

[0001] The invention relates to a safety monitoring technology for public facilities. Background Art

[0002] Public facilities, especially outdoor high-rise public facilities, such as rooftop light box advertisements, are exposed to the wind and sun, and are attacked by wind and aging parts, which cause safety hazards in terms of structural strength, leakage, fire prevention, and power overload. As we all know, aging parts will weaken the structural strength. After long-term use, the parts and the structures they form will no longer have the designed strength. Strong winds will inevitably cause parts to break or deform. If the insulation layer of electrical equipment is aged, damaged or damp, it may cause current leakage. A small amount of leakage may only cause power waste, but serious leakage may cause electric shock to people who come into contact with the equipment, causing casualties. Overload operation, short circuit or leakage may generate electric sparks, which may cause fires. Many electrical fires are caused by long-term abnormal operation of lines or equipment. If electrical equipment is in an overloaded state for a long time, it will accelerate the aging of the equipment and shorten its service life. In addition, overload may also cause heating of the line, insulation damage, and even electrical fires. However, the prior art lacks technology for monitoring safety hazards of public facilities. Summary of the invention

[0005] This technical solution can detect leakage current in real time by monitoring electrical equipment. Once the leakage current exceeds the safety threshold, the system can issue an alarm in time and automatically cut off the power supply circuit, thereby protecting the normal operation of the equipment and extending the service life of the equipment. It also reduces various safety risks caused by overload, especially avoiding the risk of electric shock to personnel. By monitoring the temperature of the danger monitor itself, when it is detected that the temperature rises abnormally due to overload or fire, the system can issue an early warning to remind the staff to take measures. Potential dangers can also be judged by the acceleration generated by the danger monitor itself being hit and the tilt and rotation angle obtained by the change in spatial posture.

The positioning module 6 is used to provide the real-time position of the danger monitor. The photoelectric output module 7 is provided with a warning light 17 and a speaker 18. The photoelectric output module 7 is used to issue the warning content in a photoelectric manner. The acceleration sensor module 8 is used to measure the acceleration of the danger monitor.

The temperature sensor module 10 is used to measure the temperature of the surrounding environment of the danger monitor. The leakage sensing module 12 is used to monitor the leakage of the power supply line. The camera module 11 is provided with a camera 19, and the camera module 11 is used to shoot the real-time environment video around the danger monitor.

[0024] The power supply line on-off device includes a housing II, and a control unit II13, a power supply unit II14, a network communication module II15, and a switch module 16 located in the housing II. The power supply unit II14, the network communication module II15, and the switch module 16 are all connected to the control unit II13 and controlled by the control unit II13. The control unit II13, the network communication module II15, and the switch module 16 are all connected to the power supply unit II14 and are powered by the power supply unit II14. The power supply line on-off device is connected to the danger handling server through the network communication module II15. The switch module 16 is used to control the power supply line of the electrical equipment to be connected or disconnected. When in use, the power supply line on-off device is connected to the power supply line of the power supply equipment.

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

[0026] Before operation, the danger monitor is placed in the public facilities, that is, the area where the electrical equipment is located, the leakage sensing module 12 is connected to the power supply line of the electrical equipment, and the switch module 16 is connected to the power supply line of the electrical equipment, so as to monitor the electrical equipment. First, initialize the danger monitor, configure the danger monitor with information corresponding to the address, the recipient information of the danger, and the warning content, set the image trigger content ITC and the acceleration trigger threshold ASTC to 20m / s 2 , angle trigger threshold ATC is 3 degrees, temperature trigger threshold TTC is 90 degrees Celsius, leakage current intensity trigger threshold ETC is 0.1mA; set image trigger content ITD, acceleration trigger threshold ASTD to 50m / s 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 danger monitor. The values ​​of acceleration, angle, temperature, and current recorded here will be adjusted in a selective manner according to the actual working conditions, so the values ​​will be different in other embodiments.

[0027] When working, when there is one or more of the five triggering conditions, including open flames and / or thick smoke in the video that meets the image trigger content ITC, acceleration greater than the acceleration trigger threshold ASTC, angle greater than the angle trigger threshold ATC, temperature greater than the temperature trigger threshold TTC, and current greater than the leakage current intensity trigger threshold ETC, the danger monitor sends the real-time location, the recipient information of the danger, and the real-time environmental video corresponding to the triggering condition, one or more abnormal data among the detected acceleration, detected angle, detected temperature, and detected current to the danger processing server, and the danger monitor issues a warning content at the same time. Then, the danger processing server reports the danger warning information including at least the real-time location and the information corresponding to the address according to the recipient information of the danger; two or more recipient information of the danger can be set in the danger monitor, and the danger processing server reports the danger warning information according to all the recipient information of the danger.

[0028] The image trigger content ITD is also open flame or thick smoke, or both, but compared with the open flame or thick smoke, or both in the image trigger content ITC, the open flame or thick smoke, or both in the image trigger content ITD appear to be stronger.

[0029] After the above situation occurs, when the video contains stronger open flames and / or thick smoke that meets one or more of the five triggering conditions of image trigger content ITD, acceleration greater than acceleration trigger threshold ASTD, angle greater than angle trigger threshold ATD, temperature greater than temperature trigger threshold TTD, and current greater than leakage current intensity trigger threshold ETD, the danger monitor sends the real-time location, the recipient information of the danger, and the real-time environment video corresponding to the triggering condition, the acceleration obtained by detection, the angle obtained by detection, the temperature obtained by detection, and one or more abnormal data of the current obtained by detection to the danger processing server, and at the same time, the danger monitor issues a warning content, and the danger processing server issues an instruction to disconnect the power supply line to the power supply line disconnection device, prompting the power supply line disconnection device to form a disconnected state on the power supply line. Then, the danger processing server reports the danger warning information including at least the real-time location and the information corresponding to the address according to the recipient information of the danger; two or more recipient information of the danger can be set in the danger monitor, and the danger processing server reports the danger warning information according to all the recipient information of the danger.

[0030] It can be seen that the settings of image trigger content ITC, acceleration trigger threshold ASTC, angle trigger threshold ATC, temperature trigger threshold TTC, and leakage current intensity trigger threshold ETC are in line with the state at the beginning of the dangerous situation; while the settings of image trigger content ITD, acceleration trigger threshold ASTD, angle trigger threshold ATD, temperature trigger threshold TTD, and leakage current intensity trigger threshold ETD are in line with the state where the dangerous situation tends to be intense. These initialization contents are set according to the working conditions, and the values ​​of the former group of parameters are generally smaller than those of the latter group of parameters.

[0031] The danger monitor has at least two recipient information of the danger, and the danger processing server reports the danger warning information according to all the recipient information of the danger.

[0032] During the communication between the danger monitor and the danger handling server, the danger handling server can call the video data in any danger monitor; when the danger handling server sends an instruction to the power line switching device to connect the power line, it can prompt the power line switching device to form a connected state on the power line, so that the electrical equipment monitored by the danger monitor on the power line can be controlled.
