[0002] Pole towers are one of the basic equipment in overhead distribution lines, used to support transmission lines at high altitudes. During the installation of pole towers and the operation and maintenance of high-altitude power equipment, it is inevitable that workers will need to climb the pole towers to perform high-altitude operations. Therefore, it is crucial to ensure the safety of workers working at high altitudes.

[0003] At present, when workers perform high-altitude operations on pole towers, they usually use a safety belt that is hung high and used low to protect themselves from falling. However, if the hook rope fails to be fastened to the hanging point, or if the safety belt rope breaks due to external force, the protective effect of the safety belt will be ineffective. Therefore, the current working safety of workers at high altitude is low. Summary of the Invention

[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] First of all, it should be understood that during the process of high-altitude operations, it is necessary to provide fall protection for high-altitude operators to ensure their personal safety. Taking pole tower operations as an example, when operators are climbing pole towers or performing high-altitude operations on pole towers, they generally use a high-hanging and low-use safety belt to prevent falls from heights. The hook of the safety belt needs to be fastened to a firm hanging point, so that when the operator suddenly falls, the rope does not pull the person for more than 2 meters; however, in actual application scenarios, if the hook rope is not fastened to a firm hanging point, or the operator suddenly falls and the distance to pull the person exceeds 2 meters, or the safety belt rope falls off and breaks due to external force damage, the safety belt will not be able to effectively prevent the high-altitude operator from falling from height. If the operator loses protection on the pole tower, he will fall at an extremely fast speed, which poses a great safety hazard. Therefore, there is an urgent need for a fall protection method for high-altitude operators that can improve the working safety of high-altitude operators.

[0046] In one embodiment, Figure 1As shown, a fall protection method for workers working at heights is provided. This embodiment takes the application of this method to a terminal as an example. The terminal includes but is not limited to a personal computer, a laptop computer, a smart phone, and a tablet computer. The terminal is deployed with a fall protection system for workers working at heights. The user tag processing system includes an acquisition module and a control module. The acquisition module is used to obtain the motion state information of the falling object monitored within the effective monitoring area of ​​the tower, wherein the motion state information represents the motion characteristics of the falling object falling from the high altitude position of the tower to the bottom position of the tower; the control module is used to control the airbag device to execute the corresponding airbag according to the motion state information when the falling object is identified as a worker working at height. Start the operation to protect the workers at heights from falling; by acquiring information interaction between the module and the control module, in the process of protecting the workers at heights from falling, the motion state information of the falling object in the effective monitoring area of ​​the tower is collected in real time, and when it is identified that the falling object is a worker at heights, based on the motion state information, the airbag device is controlled to perform the corresponding airbag start-up operation, and the fall of the workers at heights is protected by the cushioning of the airbag. This can achieve the purpose of protecting the workers at heights from falling by correctly starting the airbag device while avoiding the phenomenon of mis-starting the airbag device caused by the fall of non-workers at heights, so that the working safety of workers at heights can be improved. It can be understood that this method can also be applied to servers, and can also be applied to systems including terminals and servers, and implemented through the interaction between terminals and servers. In this embodiment, the method includes the following steps 202 to 204. Among them:

[0047] Step 202: obtaining motion state information of a falling object monitored within an effective monitoring area of ​​the tower, wherein the motion state information represents motion characteristics of the falling object falling from a high altitude position of the tower to a bottom position of the tower.

[0048] It should be noted that the fall protection system for high-altitude workers deployed at the terminal can be connected to the monitoring device for communication, so as to obtain the motion status information of the falling object; the effective monitoring area of ​​the tower represents the area covered by monitoring devices such as cameras, lidars or sensors, which can effectively capture the motion range of the falling object, which can be specifically defined by the actual height of the tower, the actual operating radius of the high-altitude workers and the detection capability of the monitoring equipment; specifically, if the height of the tower is 25 meters, the monitoring device is a lidar device, the horizontal detection radius of the lidar device is 6 meters, and the vertical coverage height is 0~30 meters, then the effective monitoring area of ​​the tower is a cylindrical space area with a radius of 6 meters and a height of 0~30 meters centered on the tower; the falling object represents the object that sends a falling motion within the effective monitoring area of ​​the tower, which can specifically be a high-altitude worker, a leaf, a film or Tools, etc.; the motion state information characterizes the motion characteristics of the falling object falling from a high altitude position of the tower to the bottom position of the tower, which can be specifically position, speed, acceleration or attitude angle, etc.; for example, in one feasible method, the monitoring device is an airbag device, and the airbag device is also deployed with a lidar detector, wherein the lidar detector has a horizontal field of view of 120°, a vertical field of view of 20°, a full-frame ultra-large detection field of view of 120°×20°, a point cloud density of 1.8 million, an effective monitoring distance of 250 meters, and an AI processor is installed inside the lidar detector, which can provide 200TOPS-400TOPS computing power, support multi-sensor fusion and real-time decision-making, and the lidar detector is installed at the root of the tower at a height range of 1 to 1.4 meters from the ground. Preferably, the lidar detector is installed at a height of 1.2 meters from the ground.

[0049] It should be noted that the high-altitude position of the tower represents the working position at a certain height from the ground, which can be the 10-meter working platform of the tower, the 15-meter maintenance ladder position or the current working position of the high-altitude workers; the bottom position of the tower represents the ground foundation area of ​​the tower, which can be the final landing point of the falling object under the action of gravity; by obtaining the motion state information of the falling object, the motion characteristics of the falling object during the falling process can be effectively analyzed.

[0050] As an example, step 202 includes: monitoring in real time whether there is a falling object in the effective monitoring area of ​​the tower, and when a falling object is detected, receiving motion status information of the falling object sent by the monitoring device.

[0051] Step 204 : When it is identified that the falling object is a person working at height, the airbag device is controlled to execute a corresponding airbag activation operation according to the motion state information to prevent the person working at height from falling.

[0052] It should be noted that the monitoring device may also have a built-in AI (Artificial Intelligence) algorithm, which can accurately distinguish different types of falling objects such as non-high-altitude workers and high-altitude workers through manual training and autonomous learning. The airbag activation operation is performed only when the falling object is identified as a high-altitude worker, thereby avoiding the false triggering of the alarm signal and the failure of the airbag to deploy. For example, in one feasible method, it is possible to determine whether the falling object is a high-altitude worker by identifying whether there is identification information in the image corresponding to the falling object. The airbag device is a safety protection device deployed at the bottom of the tower, which can form a cushion by rapid inflation, thereby reducing the impact force of a person falling to the ground. It is understandable that the airbag device can be built into the monitoring device or set independently. After the airbag activation operation is triggered, the airbag device can be activated to a preset height. Specifically, in some feasible embodiments, after receiving the activation signal, the airbag device autonomously inflates 90% within 0.3 seconds and inflates 10% within the subsequent 0.1 seconds to maintain rigidity.

[0053] As an example, step 204 includes: when it is detected that the falling object carries specific identification information, identifying the falling object as a person working at height, and when the motion state information is greater than a preset information threshold, controlling the airbag device to perform a corresponding airbag activation operation to protect the person working at height.

[0054] The above-mentioned fall protection method for workers working at heights first performs safety monitoring in the effective monitoring area of ​​the pole tower, and when a falling object is detected in the effective monitoring area of ​​the pole tower, the motion state information of the falling object is immediately obtained, wherein the motion state information represents the motion characteristics of the falling object falling from the high altitude position of the pole tower to the bottom position of the pole tower; finally, when the falling object is identified as a worker working at heights, the airbag device is controlled to execute the corresponding airbag activation operation according to the motion state information to protect the worker working at heights from falling; since the motion state information of the falling object can be monitored in the effective monitoring area of ​​the pole tower, the pole tower can be found in time. By effectively monitoring falling phenomena in the area, and then controlling the airbag device to execute the airbag activation operation only when it is identified that the falling object is a high-altitude worker, the purpose of protecting high-altitude workers from falling can be achieved by correctly activating the airbag device while avoiding the phenomenon of incorrect activation of the airbag device caused by the fall of non-high-altitude workers, rather than relying solely on safety belts to protect high-altitude workers from falling. Therefore, the technical defect that the protective effect of the safety belt will be ineffective when the hook rope fails to be fastened to the hanging point or the safety belt rope is broken due to external force is overcome, thereby improving the working safety of high-altitude workers.

[0055] In one embodiment, Figure 2As shown, according to the motion state information, the airbag device is controlled to perform the corresponding airbag activation operation, including:

[0056] Step 302: Generate an airbag control activation signal according to the motion state information.

[0057] It should be noted that, for the scenario where the airbag device is not built into the monitoring device, the airbag device can determine whether to perform the airbag activation operation based on whether the airbag control activation signal is received; specifically, the airbag device and the monitoring device are deployed separately, then the fall protection system of the height-working personnel first receives the motion status information sent by the monitoring device, and then determines whether to generate an airbag control activation signal by judging the size relationship between the motion status information and the preset information threshold, and finally sends the airbag control activation signal to the airbag control to control the airbag device to perform the corresponding airbag activation operation.

[0058] As an example, step 302 includes: generating an airbag control start signal when it is detected that the motion state information is greater than a preset information threshold.

[0059] Step 304 : Control the airbag device to execute a corresponding airbag activation operation according to the airbag control activation signal.

[0060] It should be noted that after receiving the airbag control start signal, the airbag device performs the corresponding airbag start operation; specifically, after receiving the airbag control start signal sent by the laser radar detector, the airbag device immediately triggers the opening of the airbag to put it in an inflated state; it is understandable that one or more airbag devices may be deployed at the bottom of the tower. Based on the different protection levels of fall protection, the airbag control start signal can be used to control all the airbag devices at the bottom of the tower to open the airbags and put them in an inflated state. The airbag control start signal can also be used to control the airbag device at the bottom of the tower where the high-altitude worker falls to open the airbags and put them in an inflated state.

[0061] As an example, step 304 includes: according to the airbag control activation signal, controlling the airbag device located at the place where the high-altitude worker falls to perform a corresponding airbag activation operation.

[0062] In one feasible method, the terminal can be a mobile phone, which can receive signals from a gravity sensor, a mobile lidar or an airbag device, and then view the lidar monitoring point cloud data and monitoring images through the software on the mobile phone, and can also manually control the opening of the airbag device through the mobile phone.

[0063] In this embodiment, during the execution of the airbag activation operation, a corresponding airbag control activation signal is first generated based on the motion state information, and then the airbag control activation signal is used to control the airbag device to execute the corresponding airbag activation operation, thereby achieving the purpose of the airbag device executing the corresponding airbag activation operation under passive control. Therefore, while laying the foundation for improving the work safety of high-altitude workers, the flexibility of protection for fall protection of high-altitude workers is improved.

[0064] In one embodiment, the motion state information includes motion change characteristic information sent by a first monitoring device worn by a high-altitude worker and motion change trend information sent by a second monitoring device deployed at the bottom of a tower. An airbag control activation signal is generated based on the motion state information, including one of the following:

[0065] When it is detected that the motion change characteristic information is greater than the first preset characteristic information threshold, an airbag control start signal is generated; when it is detected that the motion change trend information is greater than the first preset trend information threshold, an airbag control start signal is generated; when it is detected that the motion change characteristic information is greater than the second preset characteristic information threshold, and the motion change trend information is greater than the second preset trend information threshold, an airbag control start signal is generated.

[0066] It should be noted that in order to improve the accuracy of generating the airbag control activation signal, different types of monitoring devices can be set to monitor different types of motion change information, so as to generate the airbag control activation signal; the first monitoring device represents the monitoring device that can be carried by high-altitude workers, which can be a gravity sensor; the second monitoring device represents the monitoring device deployed at the bottom of the tower, which can be a lidar; the motion change characteristic information represents the instantaneous motion parameters collected by the first monitoring device, which can be a gravitational acceleration value; the motion change trend information represents the continuous motion parameters collected by the second monitoring device, which can be a falling velocity value.

[0067] As an example, when the motion change characteristic information is detected to be greater than the first preset characteristic information threshold, an airbag control start signal is generated. Specifically, assuming that the first preset characteristic information threshold is , then when the real-time gravity acceleration value of the high-altitude worker is detected to be greater than In the case of detecting that the motion change trend information is greater than the first preset trend information threshold, an airbag control start signal is generated. Specifically, assuming that the first preset trend information threshold is , then when the real-time falling speed of the high-altitude worker is detected to be greater than In the case of detecting that the motion change characteristic information is greater than the second preset characteristic information threshold, and the motion change trend information is greater than the second preset trend information threshold, an airbag control activation signal is generated. Specifically, assuming that the second preset characteristic information threshold is , the second preset status information threshold is , then when the real-time gravity acceleration value of the high-altitude worker is detected to be greater than , and the falling speed is greater than Under the present invention, an airbag control start signal is generated; it can be understood that the first preset characteristic information threshold and the second preset characteristic information threshold may be the same or different, and the first preset state information threshold and the second preset state information threshold may be the same or different.

[0068] In this embodiment, by integrating the motion change characteristic information of the first monitoring device worn by the high-altitude workers and the motion change trend information sent by the second monitoring device, during the fall of the high-altitude workers, it is possible to use a single exceeding threshold value to generate a warning airbag control activation signal, and to use a double exceeding threshold value to generate a clear airbag control activation signal. Therefore, it not only ensures a rapid response to emergency situations, but also greatly reduces the false triggering rate in daily operations. Therefore, while laying the foundation for improving the work safety of high-altitude workers, it also improves the protection effect of fall protection for high-altitude workers.

[0069] In one embodiment, the method further comprises:

[0070] Acquiring initial motion change characteristic information monitored by the first monitoring device at the current monitoring position;

[0071] According to the position difference between the current monitoring position and the center of gravity position of the aerial worker, the initial motion change characteristic information is adjusted to obtain the motion state information.

[0072] It should be noted that in the motion monitoring of high-altitude workers, the installation position of the first monitoring device often does not coincide with the center of gravity position of the high-altitude workers. In order to eliminate the information deviation caused by the position difference when the high-altitude workers wear the first monitoring device, the initial motion change characteristic information can be corrected based on the position difference; the initial motion change characteristic information is the motion change characteristic information monitored by the first monitoring device based on the current position, which can be specifically the initial acceleration value or the initial displacement value, etc.; it can be understood that, assuming that the first monitoring device is a gravity sensor, the gravity sensor can be used to monitor whether the worker falls, and a monitoring gravity acceleration threshold can be set. The gravity sensor can be worn on the wrist, ankle, belt, etc. of the high-altitude worker. Different positions will result in different initial motion change characteristic information monitored.

[0073] As an example, the initial acceleration detected by the first monitoring device at the current monitoring position is obtained; based on the position difference between the current monitoring position of the first monitoring device and the center of gravity of the high-altitude worker, the rotation radius of the high-altitude worker is calculated, and the initial acceleration is corrected in combination with the acceleration deviation of the angular acceleration correction line to obtain the gravity acceleration value of the high-altitude worker. In this way, during the fall protection process for high-altitude workers, no matter how the high-altitude workers wear the first monitoring device, accurate motion status information can be obtained through the first monitoring device, thus laying the foundation for improving the accuracy of fall protection for high-altitude workers.

[0074] In one embodiment, controlling the airbag device to perform a corresponding airbag activation operation according to the airbag control activation signal includes:

[0075] Obtain the current location information of the height worker; determine the target activation height of the airbag device based on the current location information and the preset buffer distance, where the preset buffer distance represents the falling distance of the height worker during the time required for the airbag device to be fully inflated; and control the airbag device to activate to the target activation height based on the airbag control activation signal.

[0076] It should be noted that in the process of fall protection for height-up workers, the activation height of the airbag device is crucial. If the deployment height of the airbag device is too low, it may not be fully inflated. If the deployment height of the airbag device is too high, the protection effect may be reduced due to the long fall time. Therefore, when controlling the airbag device to perform the corresponding airbag activation operation, the target activation height can be calculated based on the current position of the height-up worker. The target activation height can be specifically the current height of the height-up worker minus the preset buffer distance and then minus the airbag deployment height to obtain the height value. The preset buffer distance represents the falling distance of the height-up worker within the time required for the airbag device to be fully inflated. By setting the preset buffer distance, it can be ensured that the airbag has enough time to deploy and catch during the fall.

[0077] As an example, the current position information of the person working at height is obtained; the height value of the person working at height is determined based on the current position information, and the target activation height of the airbag device is calculated based on the height value and the preset buffer distance; according to the airbag control activation signal, the airbag device is controlled to activate to the target activation height.

[0078] In this embodiment, by dynamically sensing the position of the personnel working at heights and performing precise inflation control, the airbag device is controlled to start to the target starting height based on the airbag control start signal, so that the airbag start height can be bound to the real-time position of the personnel, avoiding the limitations of traditional fixed-height airbags, and thus further improving the protection effect of fall protection for personnel working at heights.

[0079] In one practicable manner, referring to Figure 3 , Figure 3 A schematic diagram of hardware interaction for fall protection of workers working at heights, wherein the hardware includes a mobile terminal, a gravity sensor, a movable lidar monitoring device and an airbag device, and the airbag device includes an airbag, a processor and a lidar.

[0080] In one embodiment, before controlling the airbag device to perform a corresponding airbag activation operation based on the motion state information, the method further includes:

[0081] Obtain the posture information of the height-up workers; determine the motion trajectory information of the height-up workers based on the posture information and the time interval for receiving the posture information; and predict the fall risk of the height-up workers based on the motion trajectory information and motion state information.

[0082] It should be noted that in order to prevent the fall risk of high-altitude workers in advance, the fall risk prediction can be carried out through the corresponding information, so as to provide early warning when the movement state of the high-altitude workers has not yet reached the danger threshold, and gain more response time for the airbag to be activated; the posture information represents the real-time data such as the position and posture of the high-altitude workers, which can be collected by the sensors worn by the high-altitude workers; the time interval refers to the time difference between the two collections of posture information, which is used to calculate the time dimension change of the motion trajectory. For example, the first collection time of the sensor is 0s, and the second collection time of the sensor is 0.1s, then the time interval is 0.1s; the motion trajectory information represents the motion path of the high-altitude workers in space generated based on continuous posture information and time intervals; the fall risk prediction of high-altitude workers can be completed through a neural network model; specifically, the motion trajectory information and motion state information can be spliced ​​into motion feature information, and then the motion feature information can be input into the neural network model to output a label to identify whether the high-altitude worker has a fall risk prediction.

[0083] As an example, the posture information of the person working at height is obtained; based on the posture information and the time information of receiving the posture information, the motion trajectory information of the person working at height is fitted; the motion trajectory information and the motion state information are spliced ​​into motion feature information, and by inputting the motion feature information into a neural network model, the fall risk of the person working at height is predicted based on the neural network model.

[0084] In this embodiment, the posture information of the high-altitude workers is first collected, and then the motion trajectory information of the high-altitude workers is generated based on the posture information and the time interval for receiving the posture information. Finally, the fall risk prediction of the high-altitude workers is completed through the motion trajectory information and the motion state information. Therefore, the motion feature information of the high-altitude workers is integrated through the motion trajectory information and the motion state information, and the purpose of protecting the high-altitude workers from falling in advance can be achieved. Therefore, the foundation for improving the working safety of high-altitude workers is further laid.

[0085] In one practicable manner, referring to Figure 4 , Figure 4 This is a schematic diagram of a fall protection scenario for workers working at heights, in which the workers working at heights wear a gravity sensor 11 on their bodies, and a movable laser radar monitoring device 12 is installed at the bottom of a pole tower. After the workers working at heights climb up the pole tower, an airbag device 13 is installed on the pole tower. The airbag device 13 and the gravity sensor 11, the mobile terminal 14 and the gravity sensor 11, the airbag device 13 and the movable laser radar monitoring device 12, the airbag device 13 and the mobile terminal 14, and the movable laser radar monitoring device 12 and the mobile terminal 14 can all be communicatively connected, and motion change feature information can be collected through the gravity sensor 11, and motion change trend information can be collected through the movable laser radar monitoring device 12. When it is detected that the motion change feature information is greater than a second preset feature information threshold and the motion change trend information is greater than the second preset trend information threshold, an airbag control start signal is generated, and finally, according to the airbag control start signal, the airbag device is controlled to perform a corresponding airbag start operation.

[0086] Since the movement status information of the falling object can be monitored within the effective monitoring area of ​​the tower, the falling phenomenon within the effective monitoring area of ​​the tower can be discovered in time, and the airbag device is controlled to perform the airbag activation operation only when the falling object is identified as a high-altitude worker. This can achieve the purpose of protecting high-altitude workers from falling by correctly activating the airbag device while avoiding the phenomenon of incorrect activation of the airbag device caused by the fall of non-high-altitude workers, rather than relying on safety belts to protect high-altitude workers from falling. Therefore, it overcomes the technical defect that the protective function of the safety belt will be ineffective when the hook rope fails to be fastened to the hanging point or the safety belt rope is broken due to external force damage, thereby improving the working safety of high-altitude workers.
