Description

Technical Field

[0001] The present invention relates to the technical field of safety protection for high-altitude operations, and particularly to a safety protection method, system, device and medium for high-altitude operations. Background Art

[0002] As a key equipment to ensure the life safety of operators in industries such as construction, electricity, and communication, the safety belts for high-altitude operations have made certain progress in structural design and function optimization in recent years. The safety belts on the market mainly adopt a three-point structure design, which restricts the human body through three fixing belts on the shoulders, chest, and waist, and are widely used in fields such as high-altitude operations, automotive safety, aviation protection, and amusement equipment. The three-point safety belt, due to its simple structure and convenient wearing, meets the basic safety protection requirements to a certain extent.

[0003] However, there are still many deficiencies in the existing technologies, which seriously affect the safety protection effect on operators. On the one hand, the existing safety belts lack the function of monitoring the wearing state and giving warnings. When the operator wears them incorrectly or the hook accidentally disengages, warnings cannot be issued in time, increasing the safety hazards of high-altitude operations. On the other hand, the protection method of traditional safety belts is relatively passive. It only reduces the damage through stretching and buffering after a fall occurs, and cannot avoid collisions with surrounding objects during the fall process, resulting in a relatively high risk of secondary injuries. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings.

[0028] Figure 1 It is a flow structure diagram of the safety protection method for working at heights. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0030] Example 1, referring to Figure 1 , which is the first embodiment of the present invention. This embodiment provides a method for improving the short-term high-frequency energy storage efficiency, including:

[0031] S1. Real-time collect target data through sensors, where the target data includes human body posture data, safety belt tension data and environmental parameters.

[0032] Furthermore, the safety belt adopts a five-point structure design and is composed of a waist belt, two shoulder straps, a chest strap and two leg straps. Among them, the two shoulder straps are connected through the chest strap;

[0033] It should be noted that the waist belt wraps around the operator's waist to provide the main horizontal support force; the two shoulder straps pass over the shoulders, cross at the back and are connected to the waist belt. The chest strap passes horizontally across the chest to connect the two shoulder straps in front of the chest, enhancing the stability of the upper body; the two leg straps wrap around the root of the thighs respectively and are connected to the waist belt. This five-point layout can evenly disperse the external forces on the human body during high-altitude operations from multiple directions, avoiding the situation of excessive force on a single point. For example, when the operator falls, the impact force can act on the muscle groups of the shoulders, chest, waist and thighs through the five straps at the same time, effectively reducing the local stress intensity and reducing the risk of body injury caused by the concentration of the impact force.

[0034] It should be further noted that the wearing of the five-point seat belt includes the following steps:

[0035] First, wrap the waist belt around the operator's waist, adjust the position of the waist belt so that it fits comfortably around the waist, and then fasten it with the buckle on the waist belt. Ensure that the tightness of the waist belt is moderate, which can provide stable support and will not be too tight to affect breathing and movement.

[0036] Next, pass the two shoulder straps over the shoulders respectively, making the shoulder straps in the appropriate position on the shoulders to avoid strangling the shoulders. After the shoulder straps cross at the back, they are connected to the waist belt through an adjustable sliding sleeve mechanism. According to the height and body type of the operator, appropriately adjust the position of the sliding sleeve to ensure that the shoulder straps can evenly distribute the pressure on the shoulders.

[0037] Pass the chest strap horizontally across the chest to connect the two shoulder straps and fasten it with the buckle on the chest strap. The position of the chest strap should be in the middle of the chest and at a moderate height, which can effectively prevent the shoulders from slipping and will not cause excessive pressure on the chest.

[0038] Finally, wrap the two leg straps around the root of the thighs respectively, connect them to the waist belt and fasten the buckles. Adjust the tightness of the leg straps to ensure that the leg straps can firmly fix the thighs and will not affect the blood circulation and movement of the legs. During the wearing process, the operator should carefully check whether each buckle is fastened and whether the webbing is twisted, knotted, etc. After ensuring that the seat belt is correctly worn, high-altitude operations can be carried out.

[0039] The seat belt also includes a sliding sleeve mechanism provided at the connection between the upper end of the waist belt and the shoulder strap. Among them, setting the sliding sleeve mechanism at the key part of the seat belt main structure that connects the waist and the shoulders can directly affect the dynamic adaptability of the seat belt during use and the restraint effect on the human body.

[0040] It should be noted that the sliding sleeve mechanism, as a movable connecting component, allows the harness to slide dynamically within a certain range according to the movements of the human body. When the operator performs actions such as bending, turning, and stretching, the harness can freely slide within the sliding sleeve as the body posture changes, adjusting the tension distribution among the straps in real time, maintaining a stable restraint on the human body, preventing the safety belt from shifting, twisting, or being overly tightened locally due to limb movements, and ensuring that the safety belt can always fit the human body and provide uniform and effective protection during various complex working actions.

[0041] Furthermore, it should be noted that a control chip is provided inside the safety belt for analyzing and processing the acquired target data.

[0042] Preferably, the webbing of the safety belt is made of a composite material of aramid fiber and ultra-high molecular weight polyethylene fiber, with a tensile strength 30% higher than that of traditional polyester fiber webbing, and it is wear-resistant and corrosion-resistant. The metal fittings are made of high-strength and lightweight aviation aluminum alloy material and are subjected to surface anodizing treatment. They not only have light weight, high strength, and strong corrosion resistance, but also enhance the surface hardness and wear resistance, ensuring reliability and service life in harsh working environments.

[0043] Furthermore, the sensors include an attitude sensor, a tension sensor, a pressure sensor, a temperature sensor, a humidity sensor, and a wind speed sensor. Among them, the attitude sensor is used to sense the body posture of the operator, including information such as the tilt angle, rotation direction, and speed.

[0044] It should be noted that the tension sensors are distributed at the key stress-bearing parts of the waist belt, shoulder strap, and leg straps for real-time monitoring of the tensile force changes of the corresponding straps. The attitude sensor is installed at the connection between the back and the hook for real-time monitoring of the back posture changes of the operator during high-altitude work. Further installing the attitude sensor near the waist belt, shoulder strap, chest strap, and leg strap parts can also synchronously obtain the attitude information of the corresponding parts. Through the coordinated action of the tension sensor and the attitude sensor, not only can the tensile force changes of each part be monitored, but also the state of the safety belt and the human body can be comprehensively sensed. For example, when the operator makes a large stretching movement, the attitude sensor at the key stress point can monitor the attitude changes caused by limb movements, and cooperate with the tension sensor to obtain more accurate real-time target data.

[0045] Furthermore, it should be noted that the pressure sensors are distributed and installed at the buckles of the chest strap, waist belt, and leg straps, and the temperature sensor, humidity sensor, and wind speed sensor are installed on the surface of the safety belt to monitor the environmental parameters of the working site.

[0046] Furthermore, the environmental parameters include at least one of temperature, humidity, and wind speed.

[0047] S2. Determine whether the acquired target data meets the fall risk condition according to a preset rule, where the preset rule is built into the control chip.

[0048] Further, the fall risk condition includes at least one of the following:

[0049] The body tilt angle exceeds the safety threshold. Here, the safety threshold includes a body tilt angle threshold and a duration threshold, and both can be set according to the actual situation. This technical solution does not limit the safety threshold. In an optional implementation, the safety threshold is 30°, and the duration threshold is 0.2 s.

[0050] The sudden change amplitude of the seat belt tension exceeds the preset range. Here, the preset range can be set according to the actual situation. This technical solution does not limit the preset range. In an optional implementation, the preset range is that the sudden change amplitude exceeds 200 N within 0.2 s.

[0051] The environmental parameters exceed the safety threshold. Here, the safety threshold of the environmental parameters includes at least one of a temperature safety threshold, a humidity safety threshold, and a wind speed safety threshold. Further, the safety threshold can be set according to the actual situation. This technical solution does not limit the preset range. In an optional implementation, the temperature safety threshold is below -10°C or above 40°C, the humidity safety threshold is a relative humidity of 90%, and the wind speed safety threshold is 10 m / s.

[0052] It should be noted that the environmental parameters are acquired by temperature sensors, humidity sensors, and wind speed sensors arranged on the seat belt.

[0053] S3. When it is determined that there is a fall risk, trigger the drive structure to tighten the seat belt webbing within a preset time to restrict the displacement of the human body. Here, the drive structure is arranged on the seat belt (waist belt, shoulder belt, chest belt, and leg belt) and adjusts the seat belt by receiving an instruction sent by the control chip. Further, when the drive structure receives the adjustment instruction sent by the control chip, it restricts the displacement of the human body by contracting the webbing of the seat belt. The preset time can be set according to the actual situation. This technical solution does not limit the preset time. In an optional implementation, the preset time is 0.5 s.

[0054] In an alternative embodiment, the drive structure includes a micro servo motor, a transmission component driven by the micro servo motor (where the transmission component uses gear transmission), and a winding wheel driven by the transmission component to rotate. One end of the webbing of the seat belt is fixedly wound around the winding wheel.

[0055] It should be noted that when the control chip determines that the current situation meets the fall risk conditions according to the preset rules, an adjustment instruction is sent to the drive structure, and further, the seat belt is retracted through the drive structure to restrict the displacement of the human body, and the impact displacement during a fall is minimized as much as possible.

[0056] Furthermore, it should be noted that the adjustment of the seat belt by the drive structure is carried out in real time in the following manner:

[0057] When the body tilt angle of the operator fluctuates slightly near the safety threshold (the up and down fluctuation does not exceed 5%), or the rotation speed is slightly faster but not at a dangerous level, the system determines it as a mild posture change. At this time, the drive structure only slightly adjusts the tension of the seat belt webbing, and the fine-tuning range may be between 5% - 10% (the fine-tuning range of 5% - 10% refers to the ratio of the tightened length of the webbing to its initial length), ensuring that the seat belt can follow the human body movements, maintain a comfortable fit, and at the same time provide a certain degree of restraint to prevent the posture from deteriorating further;

[0058] When the body tilt angle approaches the safety threshold and lasts for a long time, or the rotation speed significantly increases, the system determines it as a moderate posture change. The adjustment range of the drive structure is approximately 10% - 30%, strengthening the restraint on the operator's body and reducing the fall risk. During the tightening process, the posture change is continuously monitored. If the posture returns to normal, the motor relaxes the webbing appropriately;

[0059] When the body tilt angle exceeds the safety threshold, or the rotation speed is extremely fast and there are obvious signs of falling, the system determines it as a severe posture change. The drive structure fully and quickly tightens the webbing, causing the webbing tension to increase rapidly by more than 30%, tightly restraining the operator's body within the safe range, and minimizing the fall impact displacement to the greatest extent.

[0060] Furthermore, the target data also includes pressure data, where the pressure data is obtained through a pressure sensor set on the seat belt;

[0061] It should be noted that when the operator buckles the buckle, the pressure sensor at the buckle position receives a certain pressure, generates a corresponding electrical signal, and transmits this signal to the control chip.

[0062] The method also includes judging whether an abnormal wearing state is met according to the obtained pressure data through a preset rule;

[0063] When it is determined that there is an abnormal wearing state, an alarm is given through an alarm device.

[0064] It should be noted that when the preset rule determines that there is an abnormal wearing state, an instruction is sent to the alarm device through the control chip to achieve the alarm function.

[0065] It should be further noted that the alarm through the alarm device includes alarming through the sound and light alarm installed on the safety belt, sending instructions to the intelligent safety helmet by the control chip to trigger the vibration and voice prompt of the intelligent safety helmet, and receiving the alarm information sent by the control chip by the remote supervision platform and marking the location of the dangerous state, etc.

[0066] Furthermore, the abnormal wearing state includes that the buckle is not fully closed or accidentally loosened;

[0067] It should be noted that once the buckle is not fully fastened or accidentally loosened during the operation, the pressure sensor detects the pressure change and immediately sends an alarm instruction through the control chip to the alarm device to achieve the alarm. That is, the sound and light alarm emits a flash and a high-decibel alarm sound to remind the operator to check and fasten the buckle again in time. At the same time, the alarm signal will also be transmitted to the handheld terminal of the on-site supervisor through the wireless communication module so that the supervisor can grasp the on-site situation in real time and take measures to correct unsafe behaviors in time.

[0068] The suspension point of the safety belt is lower than the working position.

[0069] It should be noted that the inclination sensor set at the connection between the back of the safety belt and the hook obtains the inclination angle data of three axes (pitch angle θ, roll angle yaw angle ψ), and combines the spatial form analysis algorithm set in the control chip to judge the suspension state of the safety belt in real time. Furthermore, the inclination sensor transmits the measured inclination angle data to the control chip, and the control chip uses the spatial form analysis algorithm for determination.

[0070] It should be further noted that the spatial form analysis algorithm takes the connection point of the back hook of the safety belt as the original element to construct a local three-dimensional coordinate system (X-axis: horizontal direction, Y-axis: vertically upward, Z-axis: depth direction), combines the height of the operator and the positions of the fixed points of the safety belt (such as the coordinates of the waistband and backband connection points), establishes a mathematical model of the spatial position relationship between the suspension point and the center of gravity of the human body, and further determines whether there is an abnormal suspension of the safety belt through the height difference and inclination angle quantization of the suspension point.

[0071] Specifically, the suspension height difference: by calculating the vertical difference between the height H 挂钩 of the hook suspension point and the working height H 作业 of the operator, when H 挂钩 <H 作业 and exceeds the safety threshold, the determination of "hanging low and using high" is triggered. Among them, the safety threshold can be set according to the actual situation, and the safety threshold is not limited in this technical solution. In an optional implementation mode, the safety threshold is 0.5m;

[0072] Inclination angle quantization: Calculate the angle between the safety belt and the vertical direction through trigonometric functions When α > 15° and the duration exceeds 0.3 seconds, it is judged as an abnormal inclination state, and an alarm is given through the alarm device.

[0073] In summary, the beneficial effects of the high-altitude operation safety protection method of the present invention are as follows: Through the innovative five-point structure design and optimized materials and processes, the safety, comfort and reliability of the high-altitude operation safety belt are significantly improved. Further, the five-point structure can evenly disperse the impact force, reduce the local stress, and reduce the risk of body injury; the setting of the control chip can tighten the safety belt in advance before the risk of falling occurs, reducing the impact displacement; the alarm mechanism can avoid accidents caused by improper wearing or incorrect suspension according to the real-time monitored wearing state, suspension state and environmental parameters.
