[0046] Example 1

[0047] Figure 1 This is a schematic diagram of a fall protection device provided in an embodiment of the present invention, with reference to... Figure 1 The fall protection device 100 in this embodiment of the invention includes: a high-altitude work safety belt and a protection module 110 and a control module 120 installed on the high-altitude work safety belt.

[0048] Specifically, the protection module 110 includes an acceleration sensor 111 and an airbag 112. The acceleration sensor 111 is electrically connected to the control module 120 and is used to sense the real-time acceleration of the worker at height and transmit the real-time acceleration to the control module 120. The control module 120 is also electrically connected to the airbag 112 and is used to control the deployment state of the airbag 112 based on the received real-time acceleration.

[0049] For example, to ensure the safety of workers at height, they must wear safety harnesses when performing work. In this embodiment of the invention, the safety harness is equipped with a protection module 110 and a control module 120. The protection module 110 includes an acceleration sensor 111 and an airbag 112. Both the acceleration sensor 111 and the airbag 112 are electrically connected to the control module 120. The acceleration sensor 111 can transmit the real-time acceleration of the worker at height to the control module 120. The control module 120 can determine whether the worker at height has fallen based on the received real-time acceleration and then output a corresponding control signal to the control terminal of the airbag to control the opening state of the airbag 112. For example, when the real-time acceleration values ​​received by the control module 120 within a preset time are all greater than or equal to a first preset threshold, it is determined that the worker at height has fallen. At this time, the control module 120 will control the airbag 112 to open to protect the falling worker at height. It should be noted that the embodiments of the present invention do not limit the specific values ​​of the above-mentioned preset time and the first preset threshold. Different high-altitude operation scenarios correspond to different preset times and the first preset threshold. Those skilled in the art can set them according to the actual high-altitude operation scenarios.

[0050] The technical solution of this invention, through the above-mentioned fall protection device 100, can determine whether a worker has fallen based on the real-time acceleration of the worker, and control the airbag 112 to open when the worker falls, so as to protect the falling worker. This solves the problem that existing safety belts lack effective protection when workers fall, and has the beneficial effect of improving the safety of high-altitude operations.

[0051] Based on the above embodiments, continue to refer to Figure 1 The fall protection device 100 also includes an alarm module 130 installed on the safety belt for working at height.

[0052] Specifically, the alarm module 130 includes a lidar 131 and an indicator unit 132. The indicator unit 132 includes at least one of an indicator light 1321, a speaker 1322, and a vibrator 1323. The lidar 131 is electrically connected to the control module 120 and is used to detect the surrounding environment information of the high-altitude workers and transmit the surrounding environment information to the control module 120. The control module 120 is also electrically connected to the indicator unit 132 and is used to control the working state of the indicator unit 132 based on the received real-time acceleration and surrounding environment information.

[0053] For example, in this embodiment of the invention, the safety belt worn by the high-altitude worker is also equipped with an alarm module 130. The alarm module 130 includes a lidar 131 and an indicator unit 132. Both the lidar 131 and the indicator unit 132 are electrically connected to the control module 120. The lidar 131 can transmit the detected environmental information of the high-altitude worker to the control module 120. The control module 120 can determine the working status of the high-altitude worker based on the received real-time acceleration of the high-altitude worker and the environmental information, and then output a corresponding control signal to the indicator unit 132 to control the working status of the indicator unit 132.

[0054] This embodiment uses the indicator unit 132, which includes an indicator light 1321, a speaker 1322, and a vibrator 1323, as an example for explanation. When the distance detected by the laser radar received by the control module 120 is greater than or equal to the second preset threshold, it indicates that there are no protective facilities around the high-altitude worker and that the worker may be on the edge of the work platform, which is quite dangerous. At this time, the control module 120 will control the indicator light 1321 to flash, control the vibrator 1323 to vibrate, and control the speaker 1322 to emit a voice prompt saying "Pay attention to safety, fasten the safety buckle." This is to improve the high-altitude worker's awareness of danger and avoid situations where a fall from a height occurs due to negligence. When the real-time acceleration value of the worker at height received by the control module 120 within a preset time is less than the first preset threshold, but the direction of the real-time acceleration is continuously moving in the vertical direction, it indicates that the worker at height is in a climbing state, which is relatively dangerous. At this time, the control module 120 will also control the indicator light 1321 to flash, control the vibrator 1323 to vibrate, and control the speaker 1322 to emit a voice prompt of "Pay attention to safety, fasten the safety buckle." to improve the worker's awareness of danger and avoid falls due to negligence. When the real-time acceleration value of the worker at height received by the control module 120 within a preset time is greater than or equal to the first preset threshold, it indicates that the worker at height has fallen. At this time, the control module 120 will not only control the airbag 112 to deploy, but also control the indicator light 1321 to flash and control the speaker 1322 to emit an alarm sound to help rescuers quickly locate the fallen person and increase the probability of survival. It should be noted that the embodiments of the present invention do not limit the specific value of the second preset threshold. Different high-altitude operation scenarios correspond to different second preset thresholds, and those skilled in the art can set them according to the actual high-altitude operation scenarios.

[0055] Based on the above embodiments, continue to refer to Figure 1 The fall protection device 100 also includes a monitoring module 140 installed on the safety belt for high-altitude operations.

[0056] Specifically, the monitoring module 140 includes a camera 141 and a 5G communication chip 142. The camera 141 is electrically connected to the control module 120 and is used to record the work footage of the personnel working at height and transmit the work footage to the control module 120. The control module 120 is also electrically connected to the 5G communication chip 142 and is used to transmit the received work footage to the background monitoring device via the 5G communication chip 142.

[0057] For example, in this embodiment of the invention, the safety belt worn by the worker at height is also equipped with a monitoring module 140. The monitoring module 140 includes a camera 141 and a 5G communication chip 142. Both the camera 141 and the 5G communication chip 142 are electrically connected to the control module 120. The 5G communication chip 142 is also communicatively connected to the background monitoring device. The camera 141 can transmit the captured images of the worker at height to the control module 120. The control module 120 can transmit the received images to the background monitoring device through the 5G communication chip 142, so that the background management personnel can track the worker's work status in real time. At the same time, it can also provide more data support and traceability for safety management after a fall occurs, thereby helping to avoid similar situations and improve the safety of working at height.

[0058] Based on the above embodiments, continue to refer to Figure 1 The fall protection device 100 also includes a storage module 150 installed on the safety belt for working at height.

[0059] Specifically, the storage module 150 is electrically connected to the control module 120. The control module 120 is used to determine the direction and height of the fall based on received real-time acceleration data when a worker falls from height. The storage module 150 stores the direction and height of the fall, as well as the worker's personal information, including name, age, height, weight, and blood type. The control module 120 also controls the 5G communication chip 142 to dial emergency services based on the received real-time acceleration data and informs rescue personnel of the direction and height of the fall, as well as the worker's personal information stored in the storage module 150.

[0060] For example, in this embodiment of the invention, the safety belt worn by the worker at height is also equipped with a storage module 150. The storage module 150 is electrically connected to the control module 120. The control module 120 can determine the direction and height of the worker's fall based on the received real-time acceleration. For example, if the received real-time acceleration is negative, it indicates that the worker fell headfirst; if the received real-time acceleration is positive, it indicates that the worker fell feetfirst. The height of the fall can be calculated from the received real-time acceleration. The storage module 150 can be a high-capacity SD memory card, which can store the direction and height of the fall determined by the control module based on the received real-time acceleration, the video images captured by the camera 141, and the worker's personal information. When a worker falls from a height, i.e., when the real-time acceleration values ​​of the worker received by the control module 120 within a preset time are all greater than or equal to the first preset threshold, the control module 120 will control the communication chip 142 to call an emergency call and inform the rescuers of the direction and height of the fall and the worker's personal information stored in the storage module 150, so as to help the rescuers adopt more appropriate first aid methods and improve the survival rate of the fallen person.

[0061] Based on the above embodiments, continue to refer to Figure 1 The fall protection device 100 also includes a power module 160.

[0062] Specifically, the power module 160 is electrically connected to the control module 120. The power module 160 is used to supply power to the control module 120.

[0063] For example, the power module 160 can be a lithium battery. Compared with other types of batteries, lithium batteries have a longer battery life, which helps to improve the stability of the control module 120.

[0064] Based on the above embodiments, continue to refer to Figure 1 The airbag 112 includes a first airbag 1121 and a second airbag 1122. The high-altitude work safety belt includes a first section and a second section.

[0065] Specifically, the first airbag 1121 is installed in the first section, corresponding to the chest of the worker working at height. The second airbag 1122 is installed in the second section, corresponding to the back of the worker working at height.

[0066] It is understandable that workers at heights are more likely to suffer severe back and chest injuries when they fall. Therefore, when installing airbags, priority is given to placing them on the first and second sections of the safety belt for workers at heights, corresponding to the chest and back of the worker, in order to provide maximum protection for the faller.

[0067] Based on the above embodiments, continue to refer to Figure 1 The indicator unit 132 includes an indicator light 1321; the indicator light 1321 includes a first indicator light 13211 and a second indicator light 13212. The high-altitude work safety belt includes a first section and a second section.

[0068] Specifically, the first indicator light 13211 is located in the first section, corresponding to the chest of the worker at height. The second indicator light 13212 is located in the second section, corresponding to the back of the worker at height.

[0069] It is understandable that after a fall from a height, a worker may land on their back or chest. To avoid the indicator light 1321 being blocked, two indicator lights can be installed. One can be placed on the first section of the safety belt corresponding to the worker's chest, and the other can be placed on the second section of the safety belt corresponding to the worker's back. This will prevent the indicator light 1321 from being blocked, thus helping rescuers quickly determine the location of the fallen person and increasing the chances of survival.

[0070] As one possible implementation, the accelerometer 111 can be a triaxial accelerometer. A triaxial accelerometer can sense acceleration in three dimensions, enabling precise sensing.

[0071] As a feasible implementation method, the lidar 131 can be a millimeter-wave radar. Millimeter-wave radar has the advantages of small size, light weight, and high spatial resolution.

[0072] Example 2

[0073] Figure 2 This is a schematic diagram of a fall protection system provided in an embodiment of the present invention, with reference to... Figure 2 The fall protection system in this embodiment of the invention includes a background monitoring device 200, a power grid management platform 300, and a fall protection device 100 as described in any embodiment of the invention.

[0074] Specifically, the background monitoring device 200 is communicatively connected to the fall protection device 100 and the power grid management platform 300. The background monitoring device 200 transmits the personal information of workers performing high-altitude operations, which is linked to the fall protection device 100, to the fall protection device 100. The fall protection device 100 transmits its data to the background monitoring device 200. The background monitoring device 200 then transmits the received data from the fall protection device 100 to the power grid management platform 300.

[0075] For example, continue to refer to Figure 1 and Figure 2 The fall protection device 100 includes a protection module 110, a control module 120, an alarm module 130, a monitoring module 140, and a storage module 150. The protection module includes an acceleration sensor 111 and an airbag 112. The alarm module 130 includes a lidar 131 and an indicator unit 132. The monitoring module 140 includes a camera 141 and a 5G communication chip 142. The background monitoring device 200 is communicatively connected to the fall protection device 100. Before the worker begins work at height, the supervisor binds the worker to the fall protection device 100 through the background monitoring device 200 and transmits the worker's personal information to the device, which is then stored in the storage module 150. The device transmits the detected data to the background monitoring device 200. The data includes the real-time acceleration of the worker detected by the accelerometer 111, the surrounding environment information detected by the lidar 131, and the work footage recorded by the camera 141. In this way, the supervisor can see the worker's work footage and status in real time through the background monitoring device 200, allowing them to understand the worker's safety status and react and adjust accordingly. The background monitoring device 200 is also connected to the power grid management platform 300, and can transmit the data received from the fall protection device 100 to the power grid management platform 300. The power grid management platform 300 receives the data, stores it, and analyzes it to provide more information and decision support for safety management. It should be noted that the background monitoring device 200 can connect to multiple devices simultaneously and record the personal information of multiple workers at height. The person in charge can bind them according to actual work needs.

[0076] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
