Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage power line aerial work, and in particular relates to a safety early warning system and method for high-altitude power construction. Background Art

[0002] The safe reconstruction of high-voltage power lines is particularly important in the safety management and control of power construction. In particular, when workers carry out high-altitude operations such as tightening bolts, they must strictly follow the operating specifications: that is, they must not lose the protection of the safety belt during high-altitude operations. Existing high-altitude workers are basically equipped with safety belts, but due to the lack of intelligent early warning and timely correction of the irregular use of safety protection devices, if the workers fail to wear safety protection devices (such as safety belts) in a standardized manner, it may cause the workers to fall from high altitudes due to the loss of safety belt protection. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects in the prior art that high-altitude workers cannot be reminded in real time or the reminders are not targeted, and to provide a safety early warning system for high-altitude power construction.

[0004] In a first aspect of the present invention, there is provided a safety warning system for high-altitude construction of electric power, comprising a safety belt and a safety helmet, wherein the safety belt is provided with a main protection safety ring and a backup protection safety ring; pressure sensing devices are provided on the inner sides of the tops of the main protection safety ring and the backup protection safety ring, and speech generating devices are provided on both sides of the safety helmet near the ears;

[0005] The safety warning system also includes a background monitoring platform, which is signal-connected to the pressure sensing device and the voice generating device respectively; the background monitoring platform responds to the pressure information value monitored by the pressure sensing device to determine whether the main protection safety ring or the backup protection safety ring is hung on the climbing nails of the power tower and sends a warning voice message to the voice generating device when it is not hung.

[0006] A further solution is that the safety warning system also includes an intelligent image recognition device and an image recognition receiver;

[0007] The image recognition receivers are provided with two, which are respectively provided at the two feet of the aerial workers;

[0008] The intelligent image recognition device includes a video analysis module and a video acquisition module;

[0009] The video acquisition module is respectively connected to the image recognition receiver and the video analysis module by signal, and is used to track and record the image recognition receiver, and send the recorded video information to the video analysis module in real time;

[0010] The video analysis module analyzes the video information based on the image recognition technology of the convolutional neural network to determine the height difference between the two feet of the high-altitude worker and whether there are climbing nails between the two feet;

[0011] The video analysis module is connected to the background monitoring platform signal. When the height difference between the two feet is greater than the threshold set by the video analysis module or there are climbing nails between the two feet, the video analysis module determines it as an illegal operation and sends the violation information to the background monitoring platform. The background monitoring platform sends a warning voice message to the voice generating device.

[0012] A further solution is that the safety warning system also includes a monitoring terminal, which is connected to the background monitoring platform by signal, and the background monitoring platform sends the warning voice information to the voice generating device and synchronizes the warning information to the monitoring terminal.

[0013] A further solution is that the monitoring terminal is a handheld monitoring device, which is worn by supervisors at the high-altitude work site and is used to receive information on workers' tower climbing violations sent by a background monitoring platform.

[0014] A second aspect of the present invention provides a safety early warning method for high-altitude electric power construction, using the above-mentioned safety early warning system, specifically comprising the following steps:

[0015] Wear a safety helmet and safety belt correctly, and hang the main protection safety ring and the backup protection safety ring on the climbing nails of the power tower respectively. Adjust the hanging position of the main protection safety ring and the backup protection safety ring every time you climb;

[0016] The pressure sensing device obtains the pressure information value in real time and sends the pressure information value to the background monitoring platform;

[0017] The background monitoring platform responds to the pressure information value monitored by the pressure sensing device to determine whether the main protection safety ring or the backup protection safety ring is hung with the climbing nails of the power tower and sends a warning voice message to the voice generating device when neither the main protection safety ring nor the backup protection safety ring is hung.

[0018] A further solution is that before climbing the ladder, two image recognition receivers are respectively fixed on the two shoes of the height workers, and an intelligent image recognition device is set on one side of the power tower. The video analysis module analyzes the video information based on the image recognition technology of the convolutional neural network to determine the height difference between the two feet of the height workers and whether there are climbing nails between the two feet; when the height difference between the two feet is greater than the threshold set by the video analysis module or there are climbing nails between the two feet, the video analysis module determines it as an illegal operation and sends the illegal information to the background monitoring platform, and the background monitoring platform sends a warning voice message to the voice generating device.

[0019] A further solution is that the background monitoring platform sends the warning voice information to the voice generating device and synchronizes the warning information to the monitoring terminal at the same time.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention arranges voice generating devices on both sides of the safety helmet near the ears, and respectively arranges pressure sensing devices on the inner sides of the tops of the main protection safety ring and the backup protection safety ring. When the main protection safety ring and the backup protection safety ring are hung on the climbing nails of the power tower, at least based on the dead weight of the main protection safety ring and the backup protection safety ring, the pressure sensors will monitor the pressure information values. If the pressure information values ​​of the two pressure sensors are both 0, it means that the operator has not hung the safety ring according to the regulations. At this time, the background monitoring platform will send targeted voice (such as please hang the safety ring immediately before working) to the voice generating device for reminder, which can ensure that the high-altitude operators are protected by the safety ring at every step of climbing, thereby reducing the occurrence of safety accidents.

[0022] The present invention arranges an image recognition receiver on the shoes of the workers and arranges an image recognition device on one side of the power tower, tracks and records the image recognition receiver through the image recognition device, and a video analysis module analyzes the video information based on the image recognition technology of the convolutional neural network to judge the height difference between the two feet of the high-altitude workers and whether there are climbing nails between the two feet. A threshold is set in the video analysis module, and the peak value of the threshold is the vertical height of two adjacent climbing nails. When the height difference between the two feet is greater than the vertical height of the two adjacent climbing nails or there are climbing nails between the two feet, the video analysis module determines that it is an illegal operation. At this time, the background monitoring platform sends targeted voice (such as please climb step by step according to the specifications immediately, and offside climbing is prohibited) to the voice generating device for reminder, which can ensure that the high-altitude workers climb one step at a time, thereby further reducing the occurrence of safety accidents.

[0023] By equipping the supervisors at the construction site with monitoring terminals, the present invention can timely receive the violation information and targeted voice messages of the workers' tower climbing behaviors sent from the background monitoring platform (e.g., if Zhang San who is climbing the tower does not climb the tower in a standardized manner, please remind him to stop immediately). When multiple people are climbing the tower at the same time, early warning reminders can be carried out in a timely and targeted manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solution, design method and advantages of the present invention more clear, the present invention is further described in detail by specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a safety warning system for high-altitude construction of electric power, including a safety belt, a safety helmet, a pressure sensing device 1, a background monitoring platform 2, a voice generating device 3, a monitoring terminal 4, an intelligent image recognition device 5, and an image recognition receiver 6, wherein the safety belt is provided with a main protection safety ring 7 and a backup protection safety ring 8, and two pressure sensing devices 1 are provided, which are respectively arranged on the inner side of the top of the main protection safety ring 7 and the backup protection safety ring 8, to ensure that when the safety ring is hung on the climbing nail of the power tower, the pressure sensing device 1 at least bears the dead weight of the safety ring itself.

[0031] The background monitoring platform 2 is signal-connected to the pressure sensing device 1 and the voice generating device 3 respectively; the background monitoring platform 2 responds to the pressure information value monitored by the pressure sensing device 1 to determine whether the main protection safety ring 7 or the backup protection safety ring 8 is hung with the climbing nails of the power tower and sends a warning voice message to the voice generating device 3 when both the main protection safety ring 7 and the backup protection safety ring 8 are not hung.

[0032] There are two image recognition receivers 6, which are respectively arranged at the two feet of the aerial workers;

[0033] The intelligent image recognition device 5 includes a video analysis module and a video acquisition module; the video acquisition module is respectively connected to the image recognition receiver 6 and the video analysis module for tracking and recording the image recognition receiver 6, and sending the recorded video information to the video analysis module in real time; the video analysis module analyzes the video information based on the image recognition technology of the convolutional neural network to determine the height difference between the two feet of the high-altitude worker and whether there are climbing nails between the two feet;

[0034] The video analysis module is connected to the background monitoring platform 2 by signal. When the height difference between the two feet is greater than the threshold set by the video analysis module or there are climbing nails between the two feet, the video analysis module determines it as an illegal operation and sends the violation information to the background monitoring platform 2. The background monitoring platform 2 sends a warning voice message to the voice generating device 3.

[0035] The monitoring terminal 4 is connected to the background monitoring platform 2 by signals. The background monitoring platform 2 sends the warning voice information to the voice generating device 3 and synchronizes the warning information to the monitoring terminal 4 at the same time.

[0036] In the above, the pressure sensing device 1 is a miniature pressure sensor, which is a cube with a size of 5x5x5mm. It is mainly installed on the inner side of the safety ring of the seat belt by magnetic attraction, and has the function of calculating pressure information with extremely high sensitivity and transmitting it to the system background.

[0037] The backend monitoring platform 2 mainly has two functions. First, it can synchronously collect the pressure information of the two micro pressure sensors and make a judgment. When the received pressure information is 0, it sends the warning information to the portable voice generator and the portable monitoring terminal to trigger them to perform a voice warning action; second, it receives the warning signal of the intelligent image recognition device and synchronously sends it to the portable voice generator and the portable monitoring terminal to trigger them to perform a voice warning action.

[0038] The voice generator is installed on the worker's helmet by magnetic stickers, close to the ear. It has a built-in signal receiver and voice player. When it receives warning information (pressure warning, action warning), it can trigger the corresponding voice warning. The volume, voice type, and voice content can all be set manually.

[0039] The monitoring terminal 4 is worn by the supervisor at the aerial work site, and can promptly receive the violation information of the workers' tower climbing behavior transmitted from the monitoring system, and can also promptly remind the supervisor to carry out targeted early warning reminders when supervising multiple people climbing the tower.

[0040] The intelligent image recognition device 5 is mainly composed of an intelligent camera and a support rod. Among them, the intelligent camera includes a video analysis module and a video acquisition module, which are mainly used to take photos and record videos of the operator's tower climbing behavior. At the same time, the image recognition technology based on the convolutional neural network is calculated and analyzed on site. When the distance between the operator's two feet is greater than the vertical height of two adjacent climbing nails (generally 950mm or 1050mm, which can be set manually) and there is no climbing nail in the middle, an early warning message is sent to the background monitoring system.

[0041] Example 2

[0042] This embodiment provides a safety early warning method for high-altitude electric power construction, using the safety early warning system described in Example 1, including the following steps:

[0043] Step 1: Wear a safety helmet and safety belt correctly, and hang the main protection safety ring 7 and the backup protection safety ring 8 on the climbing nails of the power tower respectively. Adjust the hanging position of the main protection safety ring 7 and the backup protection safety ring 8 every time you climb;

[0044] Step 2: The pressure sensing device 1 obtains the pressure information value in real time and sends the pressure information value to the background monitoring platform 2;

[0045] Step 3: The background monitoring platform 2 responds to the pressure information value monitored by the pressure sensing device 1 to determine whether the main protection safety ring 7 or the backup protection safety ring 8 is hung with the climbing nails of the power tower and sends a warning voice message to the voice generating device 3 if it is not hung.

[0046] In step 3, if the pressure information values ​​of the two pressure sensors are both 0, it means that the operator has not hung the safety ring as required. At this time, the background monitoring platform will send targeted voice (such as please hang the safety ring immediately before working) to the voice generating device for reminder, which can ensure that the high-altitude workers are protected by the safety ring at every step of the climb, thereby reducing the occurrence of safety accidents.

[0047] In order to further improve the safety warning effect, before climbing the ladder, two image recognition receivers 6 are respectively fixed on the two shoes of the high-altitude workers, and the intelligent image recognition device 5 is set on one side of the power tower. The video analysis module analyzes the video information based on the image recognition technology of the convolutional neural network to determine the height difference between the two feet of the high-altitude workers and whether there are climbing nails between the two feet; a threshold is set in the video analysis module, and the peak value of the threshold is the vertical height of two adjacent climbing nails. When the height difference between the two feet is greater than the vertical height of the two adjacent climbing nails or there are climbing nails between the two feet, the video analysis module determines it as an illegal operation. At this time, the background monitoring platform sends targeted voice (such as please climb step by step according to the specifications immediately, and offside climbing is prohibited) to the voice generating device for reminder, which can ensure that the high-altitude workers climb one step at a time when climbing, thereby reducing the occurrence of safety accidents. In this embodiment, the supervisory personnel at the construction site are equipped with a monitoring terminal 4, which can promptly receive the violation information and targeted voice messages of the workers' tower climbing behavior sent from the background monitoring platform (such as Zhang San who is climbing the tower is not climbing the tower in accordance with the regulations, please remind him to stop immediately). When multiple people are climbing the tower at the same time, early warning reminders can be carried out in a timely and targeted manner.

[0048] In the above, the background monitoring platform 2 sends the warning voice information to the voice generating device 3 and synchronizes the warning information to the monitoring terminal 4 at the same time.

[0049] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
