Description

Technical Field

[0001] The present invention relates to the technical field of safe construction, and more particularly, to a method, a system and an electronic device for monitoring the position of a guardian for working at heights. Background Art

[0002] In the production site of an enterprise, the safety management of working at heights is of vital importance. The guardian needs to monitor the whole process of the operation to prevent accidents. However, the existing technical solutions do not accurately restrict the behavior of the guardian, and the situations of inadequate monitoring or false monitoring often occur. Therefore, it is urgent to standardize the behavior of the guardian to improve the safety of working at heights.

[0003] Currently, many enterprises adopt a personnel positioning system to set up an electronic fence for the area where the guardian for working at heights is located to restrict the activity range of the guardian for working at heights. However, the traditional electronic fence is usually set as a fixed area, and this method fails to adjust the electronic fence according to the dynamic changes of the operators, resulting in insufficient monitoring effect. Summary of the Invention

[0004] The problem solved by the present invention is how to realize the dynamic adjustment of the electronic fence and accurately monitor the position of the guardian for working at heights.

[0005] To solve the above problems, the present invention provides a method, a system and an electronic device for monitoring the position of a guardian for working at heights.

[0016]

[0017] where r1 represents the radius of the first circular area, θ max represents the guardianship perspective threshold, h1 represents the height value of the high-altitude worker from the reference horizontal line, and h2 represents the height of the high-altitude work guardian from the reference horizontal line;

[0018] The expression for the first circular area is:

[0019] r1 2 =(x - x1) 2 +(y - y1) 2

[0020] where, in the three-dimensional space coordinate system, x1 represents the x-axis coordinate of the horizontal plane of the high-altitude worker, and y1 represents the y-axis coordinate of the horizontal plane of the high-altitude worker;

[0021] The expression for the radius of the second circular area is:

[0022]

[0023] where r2 represents the radius of the second circular area, L max represents the guardianship distance threshold, and θ represents the guardianship perspective of the high-altitude work guardian;

[0024] The expression for the second circular area is:

[0025] r2 2 =(x - x1) 2 +(y - y1) 2 .

[0026] Optionally, the expression for the guardianship perspective of the high-altitude work guardian is:

[0027]

[0028] Wherein, in a three-dimensional space coordinate system, x2 represents the horizontal plane x-axis coordinate of the high-altitude operation guardian, and y2 represents the horizontal plane y-axis coordinate of the high-altitude operation guardian.

[0029] Optionally, the first spatial coordinate is obtained by a first detection device worn on the high-altitude operator, and the second spatial coordinate is obtained by a second detection device worn on the high-altitude operation guardian.

[0040] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by configuring the guardianship view threshold and the guardianship distance threshold, strict spatial constraint conditions can be set for the behavior of the high-altitude operation guardian. The guardianship view threshold defines the angular range within which the high-altitude operation guardian can observe the high-altitude operator, while the guardianship distance threshold ensures that a reasonable distance is always maintained between the high-altitude operation guardian and the high-altitude operator, thereby preventing the high-altitude operation guardian from being unable to effectively monitor the high-altitude operator due to view or distance problems. Secondly, based on the guardianship view threshold, the guardianship distance threshold, and the spatial coordinates of the high-altitude operator and the high-altitude operation guardian, a dynamic electronic fence area that changes with the position of the high-altitude operator is generated. This dynamic electronic fence is not only adjusted in real time based on the position of the high-altitude operator but also ensures that the high-altitude operation guardian is always within the visible range of the high-altitude operator and maintains an appropriate monitoring distance through the constraints of the guardianship view and the guardianship distance, thus improving the accuracy of the guardianship effect. Moreover, by obtaining and judging the spatial coordinates of the guardian in real time, when the high-altitude operation guardian exceeds the set dynamic electronic fence area, an absence or departure warning signal is output, which can ensure that when the positioning of the high-altitude operation guardian is abnormal, the management personnel are timely reminded to take necessary safety measures, enhancing the safety of high-altitude operations. Finally, in a complex high-altitude operation environment, the relative positions of the high-altitude operator and the high-altitude operation guardian may change continuously. The combination of the dynamic electronic fence area and the guardianship threshold enables the dynamic electronic fence area to respond to this change, ensuring the efficient monitoring of high-altitude operations. The present invention can achieve the dynamic adjustment of the electronic fence and accurately monitor the position of the high-altitude operation guardian. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] An electronic fence is a virtual fence system based on a fixed area, usually used to monitor and restrict the activities of people or objects within a specific area. The electronic fence does not have an actual boundary like a physical fence, but defines a virtual boundary area through technologies such as sensors, positioning systems, or radio frequency identification (RFID). Once entering or leaving this area, the relevant supporting equipment will issue an alarm or trigger corresponding safety measures.

[0052] In high-altitude operations, the absence or departure of the high-altitude operation supervisor is one of the main causes of high-altitude operation accidents. Thus, to ensure the safety of high-altitude operations, the behavior of the high-altitude operation supervisor also needs to be regulated. In the prior art, the movement of the high-altitude operation monitor is generally regulated and warned through an electronic fence. However, the limitation of the traditional electronic fence is that it only monitors within a set fixed area and cannot be dynamically adjusted according to the actual changes during the operation. For example, in high-altitude operations, the height and position of the operator may change, and the traditional electronic fence cannot effectively adapt to this change, resulting in low monitoring accuracy. Therefore, it may not be able to accurately restrict the position of the high-altitude operation supervisor, and thus the effectiveness of monitoring the operation process is weak.

[0053] To solve the above problems, the present invention provides the following solutions.

[0054] Referring to Figure 1 , the present invention provides a method for monitoring the position of a high-altitude operation supervisor, including:

[0055] S11. Configure the monitoring view angle threshold and the monitoring distance threshold for high-altitude operations.

[0056] It should be noted that the monitoring view angle refers to the line-of-sight angle between the high-altitude operation supervisor and the high-altitude operator. Specifically, it is the angle between the line of sight of the supervisor's eyes and the horizon. To ensure the effective field of view of the supervisor; the monitoring distance refers to the spatial distance between the high-altitude operation supervisor and the high-altitude operator, ensuring that the high-altitude operation supervisor is always near the high-altitude operator and can promptly discover and handle sudden safety problems. The monitoring distance threshold is set as the farthest effective monitoring distance between the high-altitude operation supervisor and the high-altitude operator.

[0057] During implementation, the monitoring view angle threshold and the monitoring distance threshold can be configured according to the requirements and specific conditions of the operation environment. For example, during implementation, the monitoring view angle threshold can be set according to factors such as the working height and the structure of the operation platform; the monitoring distance threshold can be flexibly set according to the operation scenario (the visible situation on-site).

[0058] S12. Real-time obtain the first spatial coordinate of the high-altitude operator and the second spatial coordinate of the high-altitude operation supervisor.

[0059] Specifically, the high-altitude operator refers to the person who is performing high-altitude operations, and its first spatial coordinate can be obtained through the detection device worn on his body. The high-altitude operation supervisor refers to the person responsible for supervising and protecting the safety of the operator, and its second spatial coordinate can also be obtained through the detection device worn on his body.

[0060] S13. Generate a dynamic electronic guardrail area that changes with the first spatial coordinate based on the guardianship perspective threshold, the guardianship distance threshold, the first spatial coordinate, and the second spatial coordinate. The dynamic electronic guardrail area is used to limit the movement range of the high-altitude operation guardian.

[0061] The dynamic electronic guardrail area is a virtual monitoring range, and its shape and size change in real time according to the position of the high-altitude operator (the first spatial coordinate) and the position of the high-altitude operation guardian (the second spatial coordinate). The role of the dynamic electronic guardrail area is to limit the activity range of the high-altitude operation guardian to ensure that the high-altitude operation guardian can always effectively monitor the high-altitude operator.

[0062] The guardianship perspective threshold determines the maximum range of the high-altitude operation guardian's field of vision, that is, the maximum viewing angle at which the high-altitude operation guardian can observe the high-altitude operator; the distance guardianship threshold refers to the maximum effective monitoring distance between the high-altitude operation guardian and the high-altitude operator. During the actual high-altitude production process, the radius and position of the dynamic electronic guardrail area can be adjusted in real time according to the relative positions of the high-altitude operator (the first spatial coordinate) and the high-altitude operation guardian (the second spatial coordinate). For example, when the high-altitude operator moves to a higher operation platform or changes the operation position, the guardian's viewing angle and guardianship distance will be affected, and the system will adjust the dynamic electronic guardrail area in real time to ensure that the guardian is always within the effective monitoring range.

[0063] S14. In response to the high-altitude operation start signal, judge the second spatial coordinate. If the second spatial coordinate of the high-altitude operation guardian is outside the dynamic electronic guardrail area, output a guardian absence warning signal;

[0064] S15. During the high-altitude operation process, continuously judge the second spatial coordinate in real time. If the second spatial coordinate of the high-altitude operation guardian is outside the dynamic electronic guardrail area, output a guardian departure warning signal.

[0065] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by configuring the monitoring view angle threshold and the monitoring distance threshold, strict spatial constraint conditions can be set for the behavior of the high-altitude operation guardian. The monitoring view angle threshold limits the angle range within which the high-altitude operation guardian can observe the high-altitude operator, while the monitoring distance threshold ensures that a reasonable distance is always maintained between the high-altitude operation guardian and the high-altitude operator, thereby preventing the high-altitude operation guardian from being unable to effectively monitor the high-altitude operator due to view angle or distance issues. Secondly, based on the monitoring view angle threshold, the monitoring distance threshold, and the spatial coordinates of the high-altitude operator and the high-altitude operation guardian, a dynamic electronic fence area that changes with the position of the high-altitude operator is generated. This dynamic electronic fence is not only adjusted in real time based on the position of the high-altitude operator but also, through the constraints of the monitoring view angle and the monitoring distance, ensures that the high-altitude operation guardian is always within the visible range of the high-altitude operator and maintains an appropriate monitoring distance, thus improving the accuracy of the monitoring effect. Moreover, by obtaining and judging the spatial coordinates of the guardian in real time, when the high-altitude operation guardian exceeds the set dynamic electronic fence area, an absence or departure warning signal is output, which can ensure that when the positioning of the high-altitude operation guardian is abnormal, the management personnel are timely reminded to take necessary safety measures, enhancing the safety of high-altitude operations. Finally, in a complex high-altitude operation environment, the relative positions of the high-altitude operator and the high-altitude operation guardian may constantly change. The combination of the dynamic electronic fence area and the monitoring threshold enables the dynamic electronic fence area to respond to this change, ensuring the efficient monitoring of high-altitude operations. The present invention can achieve the dynamic adjustment of the electronic fence and accurately monitor the position of the high-altitude operation guardian.

[0066] In one embodiment, the monitoring view angle threshold is the maximum allowable angle between the line of sight of the high-altitude operation guardian and the horizontal line.

[0067] It should be noted that the monitoring view angle threshold is a maximum value set according to the requirements of the operation environment and the monitoring needs. For example, the monitoring view angle threshold is set between 10 degrees and 45 degrees. The monitoring view angle threshold represents the maximum allowable angle between the line of sight of the guardian and the horizontal line. The configuration of the monitoring view angle threshold can be adjusted based on factors such as the operation environment, the working position of the high-altitude operation guardian, and the height of the high-altitude operator. For example, in the case of high-altitude operations, in order to ensure that the high-altitude operation guardian can clearly see the high-altitude operator, the monitoring view angle threshold can be appropriately increased; while in a lower operation environment, the view angle threshold may be correspondingly reduced.

[0068] Furthermore, during the high-altitude operation process, the monitoring view angle threshold can be dynamically adjusted. For example, when the high-altitude operator moves to different heights, the monitoring view angle threshold can be adjusted according to the new height and operation position to meet the monitoring requirements under different operation conditions.

[0069] In one embodiment, the guardianship distance threshold is the maximum allowable distance between the high-altitude operation guardian and the high-altitude operator.

[0070] Specifically, the guardianship distance refers to the spatial distance between the high-altitude operation guardian and the operator, and is usually calculated using the Euclidean distance in a three-dimensional coordinate system. The guardianship distance threshold defines the maximum allowable distance between the high-altitude operation guardian and the high-altitude operator. If the distance between the high-altitude operation guardian and the high-altitude operator exceeds this threshold, it means that the high-altitude operation guardian is no longer within the effective monitoring range and cannot provide effective guardianship, which may lead to safety problems.

[0071] It should be noted that the guardianship distance threshold can be dynamically adjusted according to the actual situation during the operation. For example, if the high-altitude operator moves to a higher operation platform or makes a large movement within the operation area, the system can update the guardianship distance threshold in real time according to the new position of the high-altitude operator.

[0072] In one embodiment, the dynamic electronic guardrail area is the non-overlapping area between the first circular area and the second circular area, and the first circular area and the second circular area are concentric circles.

[0073] Specifically, both the first circular area and the second circular area are centered on the current position of the high-altitude operator. The radii of these two circular areas respectively define the minimum and maximum allowable monitoring distances of the high-altitude operation guardian, thus forming an annular monitoring area. The radius of the first circular area (inner circle) is set to the minimum monitoring distance (such as 5 meters), while the radius of the second circular area (outer circle) is set to the maximum monitoring distance (such as 20 meters). The high-altitude operation guardian should be located within the annular area (i.e., the dynamic electronic guardrail area) between these two circular areas to maintain effective monitoring of the high-altitude operator.

[0074] Referring to Figure 2 and Figure 3 , the first spatial coordinate is (x1, y1, h1), the second spatial coordinate is (x2, y2, h2), and the expression for the radius of the first circular area is:

[0075]

[0076] where r1 represents the radius of the first circular area, θ max represents the guardianship viewing angle threshold, h1 represents the height value of the high-altitude operator from the reference horizontal line, and h2 represents the height of the high-altitude operation guardian from the reference horizontal line;

[0077] The expression for the first circular area is:

[0078] r1 2 = (x - x1)2 +(y - y1) 2

[0079] Wherein, in the three - dimensional space coordinate system, x1 represents the x - axis coordinate of the horizontal plane of the person working at height, and y1 represents the y - axis coordinate of the horizontal plane of the person working at height;

[0080] The expression for the radius of the second circular area is:

[0081]

[0082] Wherein, r2 represents the radius of the second circular area, L max represents the threshold value of the guardianship distance, and θ represents the guardianship angle of view of the guardian for the person working at height;

[0083] The expression for the second circular area is:

[0084] r2 2 =(x - x1) 2 +(y - y1) 2 .

[0085] Optionally, the expression for the guardianship angle of view of the guardian for the person working at height is:

[0086]

[0087] Wherein, in the three - dimensional space coordinate system, x2 represents the x - axis coordinate of the horizontal plane of the guardian for the person working at height, and y2 represents the y - axis coordinate of the horizontal plane of the guardian for the person working at height.

[0088] In this embodiment, by accurately defining the first circular area and the second circular area, the dynamic electronic fence area is dynamically adjusted according to the position of the person working at height, increasing the energy efficiency of safety management during the high - altitude operation.

[0089] Furthermore, the first spatial coordinate is obtained by the first detection device worn on the person working at height, and the second spatial coordinate is obtained by the second detection device worn on the guardian for the person working at height.

[0090] Specifically, the first detection device and the second monitoring device can be wearable devices with positioning functions, such as smart watches, GPS trackers or other portable positioning devices. These devices should be equipped with high-precision positioning technologies, such as GPS, GLONASS, Galileo or BeiDou satellite systems, as well as ground augmentation systems, such as RTK (Real-Time Kinematic). At the same time, the first detection device and the second detection device also include wireless communication components that can transmit the acquired position data (the first spatial coordinate and the second spatial coordinate) to the central processing system in real time, such as Wi-Fi, Bluetooth, LoRa or 4G / 5G networks.

[0091] In one embodiment, both the guardian absence warning signal and the guardian departure warning signal are output through a buzzer or an indicator light on the first detection device and / or the second detection device, and an alarm event is generated in the remote terminal at the same time.

[0092] Specifically, the guardian absence warning signal and the guardian departure warning signal are output through a buzzer or an indicator light on the first detection device and the second detection device. The first detection device and the second detection device are usually wearable devices, such as smart watches, sensors equipped on safety helmets or other types of portable devices. The buzzer is used to emit a sound alarm, while the indicator light provides a visual warning by flashing or changing color, so that even in a noisy working environment, the high-altitude operation guardian and the high-altitude operator can quickly realize the safety alarm, thereby improving the safety management efficiency of high-altitude operations; and when the guardian absence warning signal and the guardian departure warning signal are output, an alarm event is generated in the remote terminal at the same time, so as to facilitate the management of high-altitude operation guardians.

[0093] Referring to Figure 4 , the present invention provides a high-altitude operation guardian position monitoring system 20 for implementing any one of the above-mentioned high-altitude operation guardian position monitoring methods, including:

[0094] A parameter setting module 21 for configuring a monitoring perspective threshold and a monitoring distance threshold for high-altitude operations;

[0095] A coordinate acquisition module 22 for acquiring the first spatial coordinate of the high-altitude operator and the second spatial coordinate of the high-altitude operation guardian in real time;

[0096] A dynamic electronic fence area generation module 23 for generating a dynamic electronic fence area that changes with the first spatial coordinate based on the monitoring perspective threshold, the monitoring distance threshold, the first spatial coordinate and the second spatial coordinate, and the dynamic electronic fence area is used to limit the moving range of the high-altitude operation guardian;

[0097] The operation start judgment module 24 is configured to judge the second spatial coordinate in response to a high-altitude operation start signal. If the second spatial coordinate of the high-altitude operation guardian is outside the dynamic electronic guardrail area, an absent guardian warning signal is output.

[0098] The operation process judgment module 25 is configured to judge the second spatial coordinate in real time during the high-altitude operation. If the second spatial coordinate of the high-altitude operation guardian is outside the dynamic electronic guardrail area, a leaving guardian warning signal is output.

[0099] Compared with the prior art, the beneficial effects of this embodiment are as follows: First, the parameter setting module 21 can set strict spatial constraint conditions for the behavior of the high-altitude operation guardian by configuring the monitoring perspective threshold and the monitoring distance threshold. The monitoring perspective threshold defines the angular range within which the high-altitude operation guardian can observe the high-altitude operator, and the monitoring distance threshold ensures that a reasonable distance is always maintained between the high-altitude operation guardian and the high-altitude operator, thereby preventing the high-altitude operation guardian from being unable to effectively monitor the high-altitude operator due to perspective or distance issues. Secondly, after the coordinate acquisition module 22 obtains the first spatial coordinate of the high-altitude operator and the second spatial coordinate of the high-altitude operation guardian, the dynamic electronic guardrail area generation module 23 generates a dynamic electronic guardrail area that changes with the position of the high-altitude operation personnel based on the monitoring perspective threshold, the monitoring distance threshold, and the spatial coordinates of the high-altitude operator and the high-altitude operation guardian. This dynamic electronic guardrail is not only adjusted in real time based on the position of the high-altitude operator but also ensures that the high-altitude operation guardian is always within the visible range of the high-altitude operator and maintains an appropriate monitoring distance through the constraints of the monitoring perspective and the monitoring distance, thereby improving the accuracy of the monitoring effect. Moreover, the operation start judgment module 24 and the operation process judgment module 25 output an absent or leaving warning signal by judging the spatial coordinate of the guardian in real time when the high-altitude operation guardian exceeds the set dynamic electronic guardrail area, which can ensure that when the positioning of the high-altitude operation guardian is abnormal, the management personnel are timely reminded to take necessary safety measures, enhancing the safety of high-altitude operations. Finally, in a complex high-altitude operation environment, the relative positions of the high-altitude operator and the high-altitude operation guardian may change continuously. The combination of the dynamic electronic guardrail area and the monitoring threshold enables the dynamic electronic guardrail area to respond to this change, ensuring the efficient monitoring of high-altitude operations. The present invention can achieve the dynamic adjustment of the electronic guardrail and accurately monitor the position of the high-altitude operation guardian.
