Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to an intelligent monitoring method for a high-hanging, low-use safety belt. Background Art

[0002] High-altitude work at construction sites requires safety belts to ensure the absolute safety of construction workers and avoid injuries caused by falling. In actual use, due to the weak safety awareness or bad habits of construction workers, they often forget to fasten the safety belts and do not hang them correctly. In particular, there is no appropriate technical method to regulate and guarantee the very important "high hanging and low use" requirement. High hanging and low use means that when using high-altitude safety belts, the hanging point (i.e. the fixed point) of the safety belt should be set at a position higher than the top of the construction worker's head, and the construction worker is connected to the hanging point through the safety belt, so that the safety belt forms a "low" under the worker's body. A support. Generally speaking, "high hanging" means that the hanging point of the safety belt should be as high as possible, so as to ensure that when a fall occurs, the safety belt can be quickly tightened and the falling distance can be limited, reducing the damage to the worker's body caused by the impact of the fall. "Low use" means that workers should wear the safety belt correctly and ensure that the safety belt is located lower on the body, usually at the waist or chest, so that the impact force can be effectively dispersed when falling, protecting the worker's spine and internal organs from damage. Following the principle of "high hanging and low use" can minimize the risk of falling in high-altitude operations and protect the lives of workers.

[0003] In the prior art, Chinese patent publication number CN219225642U discloses a monitoring mechanism for an intelligent seat belt. The intelligent safety belt is provided with interconnected shoulder straps and leg straps, and the shoulder straps and leg straps are respectively connected with a chest locking belt and a waist locking belt, so that the monitoring mechanism can be conveniently loaded and unloaded, and the monitoring mechanism can be fastened to the chest locking belt to prevent the monitoring mechanism from being loosened due to the activities of the wearer, so as to prevent the monitoring mechanism from being lost, thereby improving the protectiveness of the monitoring mechanism; Chinese patent with publication number CN104800988A discloses a safety belt that automatically warns when working at heights and a method of using the same, and the safety belt includes an embedded barometer module, an acceleration sensor, a MEMS gyroscope, and a data processing module to judge the movement state of the construction personnel, remind them to wear the safety belt when working at heights, and eliminate the operation risk; Chinese patent with publication number CN117731976A discloses an intelligent safety belt supervision and early warning platform, which monitors and analyzes the safety status, physical physiology and environmental parameters of workers when working at heights in real time, so as to give early warning of possible safety incidents.

[0004] Therefore, the current safety belts do not have a good real-time detection method for high-hanging and low-use. Especially in unstable climatic conditions and complex on-site working environments, they cannot effectively remind construction workers to correctly wear and use high-altitude safety belts, and there is no targeted solution to the monitoring and early warning of "high-hanging and low-use" safety belts. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent monitoring method for high-hanging and low-use safety belts, so as to solve the problem that the safety belts in the prior art do not have a good real-time detection method for high-hanging and low-use, especially in unstable climatic conditions and complex on-site working environments, and cannot well remind construction personnel to achieve the correct wearing and use of high-altitude safety belts, and do not specifically solve the monitoring and early warning problems of the "high-hanging and low-use" of safety belts.

[0006] To achieve the above object, the present invention provides the following technical solution: a high-hanging, low-use safety belt intelligent monitoring method, the method specifically comprises the following steps:

[0007] S1: The air pressure values ​​measured by the ground-end air pressure sensor, the main body-end air pressure sensor and the hook-end air pressure sensor are transmitted to the cloud platform;

[0008] S2: Start the cloud platform system and calculate the initial state;

[0009] S3: When construction workers are climbing with safety belts, the values ​​of each air pressure sensor are monitored in real time. When the air pressure data calculation formula is greater than a preset threshold, the high hanging and low use analysis is started;

[0010] S4: When starting the high-hanging and low-use analysis, the cloud platform analyzes the received real-time air pressure data. If it is determined that the hook is in normal use, a safety signal is sent back. If it is determined that the hook is too low, a warning signal is sent back;

[0011] S5: The cloud platform wirelessly transmits the data back to the data controller at the seat belt body, which activates the alarm according to the warning status, and issues an audible and visual alarm to remind the construction personnel;

[0012] S6: When construction workers are wearing safety belts and exercising, if the difference in air pressure values ​​between the ground end and the main body end received by the cloud platform is lower than a preset threshold, it is determined that they have entered the safe area and the high-hanging and low-use analysis warning state ends.

[0013] Preferably, in step S1:

[0014] The air pressure value measured by the ground pressure sensor is recorded as P g0 ;

[0015] The air pressure value measured by the air pressure sensor at the main body is recorded as P m0 ;

[0016] The air pressure value P measured by the air pressure sensor at the hook end h0 .

[0017] Preferably, the air pressure value P measured by the air pressure sensor at the hook end is h0 The data is forwarded by the data controller to the network cloud platform via WIFI.

[0018] Preferably, in step S3, during the climbing process of the construction workers wearing safety belts, the values ​​of each air pressure sensor monitored in real time are P g and P m , the preset threshold is P T ;

[0019] When (P m -P m0 )-(P g -P g0 )>P T When high hanging and low use analysis is started, P m is the real-time data of air pressure at the main body, P g is the real-time data of ground pressure, P T Define thresholds for work at height as required by building regulations.

[0020] Preferably, in step S4, the cloud platform performs analysis based on the received real-time air pressure data:

[0021] When (P h -P h0 )-(P m -P m0 )>P dif When the hook is used normally, a safety signal is sent back;

[0022] When (P h -P h0 )-(P m -P m0 ) <P dif When the hook is judged to be too low, a warning signal is sent back.

[0023] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0024] The intelligent monitoring method for high-hanging and low-use safety belts monitors the values ​​of various air pressure sensors in real time during the climbing process of construction workers wearing safety belts. When the air pressure data calculation formula is greater than a preset threshold, the high-hanging and low-use analysis is started. When the high-hanging and low-use analysis is started, the cloud platform analyzes the received real-time air pressure data. If it is determined that the hook is used normally, a safety signal is sent back. If it is determined that the hook is too low, a warning signal is sent back. The cloud platform sends out sound and light alarms to remind the construction workers. When the construction workers are wearing safety belts and exercising, the cloud platform will determine that they have entered a safe area during this process and end the high-hanging and low-use analysis warning state. The method Taking into account the impact of weather changes on air pressure at the construction site, the use status of the safety belt hooks of construction workers in complex high-altitude working environments can be judged more accurately and in real time. It can not only quickly grasp the working status of on-site personnel to provide a basis for management departments, but also provide early warning signals in real time to more fully ensure the safety of personnel working at high altitudes. It solves the problem that the safety belts in the existing technology do not have a good real-time detection method for high-hanging and low-use, especially in unstable climatic conditions and complex on-site working environments. It cannot remind construction workers well to achieve the correct wearing and use of high-altitude safety belts, and does not specifically solve the monitoring and early warning problems of "high-hanging and low-use" of safety belts.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 3 As shown, a high-hanging, low-use safety belt intelligent monitoring method, the method specifically comprises the following steps:

[0031] S1: The air pressure values ​​measured by the ground-end air pressure sensor, the main body-end air pressure sensor and the hook-end air pressure sensor are transmitted to the cloud platform;

[0032] S2: Start the cloud platform system and calculate the initial state;

[0033] S3: When construction workers are climbing with safety belts, the values ​​of each air pressure sensor are monitored in real time. When the air pressure data calculation formula is greater than a preset threshold, the high hanging and low use analysis is started;

[0034] S4: When starting the high-hanging and low-use analysis, the cloud platform analyzes the received real-time air pressure data. If it is determined that the hook is in normal use, a safety signal is sent back. If it is determined that the hook is too low, a warning signal is sent back;

[0035] S5: The cloud platform wirelessly transmits the data back to the data controller at the seat belt body, which activates the alarm according to the warning status, and issues an audible and visual alarm to remind the construction personnel;

[0036] S6: When construction workers are wearing safety belts and exercising, if the difference in air pressure values ​​between the ground end and the main body end received by the cloud platform is lower than a preset threshold, it is determined that they have entered the safe area and the high-hanging and low-use analysis warning state ends.

[0037] The hardware in this patent includes a ground end 4, a main body end and a hook end, which are equipped with three air pressure sensors and corresponding data controllers, a ground end air pressure sensor 5 and a ground end data controller 6, a seat belt main body end air pressure sensor 3 and a data controller 2, and a hook end air pressure sensor 8 and a hook end data controller 7. The ground end 4 is provided with a mobile wireless data transmission unit, the main body end data controller 2 is provided with a mobile wireless transmission and a short-range wireless transmission unit based on WIFI, and the hook end data controller is provided with a WIFI data transmission unit that is wirelessly connected to the main body end.

[0038] The specific steps of the above method are as follows:

[0039] Before using it on site in the construction work area, place the ground end 4, the main body end and the hook end on the same elevation of the ground in the construction area. The air pressure value measured by the ground end air pressure sensor 5 is recorded as P g0 The air pressure value measured by the air pressure sensor 3 at the main body end is recorded as P m0 ; The air pressure value P measured by the air pressure sensor 8 at the hook end h0 , transmitted to the network cloud platform 10 by wireless, where P h0 The value is forwarded by the main body data controller 2 via WIFI.

[0040] Start the software on the cloud platform 10, calculate the initial state, and start real-time monitoring and analysis process;

[0041] When construction workers are wearing safety belts and climbing, they monitor the value P of each air pressure sensor in real time. g and P m ,When the air pressure data calculation formula is greater than a pre-set threshold, the high hanging and low use analysis is started.

[0042] (P m -P m0 )-(P g -P g0 )>P T

[0043] Where P m is the real-time data of air pressure at the main body, P g Real-time data of air pressure on the ground side;

[0044] P T Define thresholds for height work as required by building regulations (e.g. pressure difference from the 2m standard value).

[0045] The definition and regulations of high-altitude work in China's construction industry are mainly based on relevant laws and standards such as the "Construction Safety Inspection Standard" (JGJ59-2011) and the "Technical Specification for Safety of High-altitude Work in Construction" (JGJ 80-2016). According to these regulations, high-altitude work usually refers to work above 2 meters (including 2 meters) from the falling height reference plane.

[0046] When construction workers wear the safety belt and move in the air (i.e., when the high-hanging and low-use analysis is started), the cloud platform 10 performs analysis based on the received real-time air pressure data:

[0047] When (P h -P h0 )-(P m -P m0 )>P dif When the hook is used normally, a safety signal is sent back;

[0048] When (P h -P h0 )-(P m -P m0 ) <P dif When the hook is judged to be too low, a warning signal is sent back;

[0049] The cloud platform 10 wirelessly transmits the data to the main body controller 2 of the safety belt main body, activates the alarm according to the warning status, and issues an audible and visual alarm to remind the construction personnel;

[0050] In a possible implementation, when construction workers wear the safety belt and move in the air, the system starts the "high hanging and low use" analysis, and the cloud platform 10 makes a judgment based on the air pressure data received in real time. Specifically:

[0051] Analyze based on the pressure difference. When the pressure difference (P h -P h0 ) and the pressure difference between the main body end (P m -P m0 ) is greater than the preset threshold value Pdif, indicating that the hook is in a higher position, which meets the safety specification of "high hanging and low use", and the system determines that the hook is in normal use. At this time, the cloud platform 10 sends a safety signal back to the body-end data controller 2 of the seat belt body, and the system remains in a normal state without triggering an alarm;

[0052] If the cloud platform 10 detects the pressure difference at the hook end (P h -P h0 ) and the pressure difference between the main body end (P m -P m0 ) is less than the preset threshold value P dif , indicating that the hook position is too low, which does not meet the "high hanging and low use" requirement. At this time, the system determines that the hook is not used correctly or the hook position is too low, and there may be a risk of falling. The system will trigger the early warning mechanism and send a warning signal back to the main body data controller 2;

[0053] When the main body end data controller 2 receives the early warning signal, it immediately starts the sound and light alarm to remind the construction personnel to pay attention to the hook state of the safety belt. Through the sound and light prompt of the alarm, the construction personnel can adjust the use state of the safety belt in time to avoid the occurrence of safety accidents.

[0054] By analyzing the data from the air pressure sensor, the system can accurately determine the height position of the hook when the construction workers wear the safety belt. The comparison of the air pressure difference with the preset threshold value Pdif enables the system to dynamically determine whether the hook is in the correct use state in different construction environments, ensuring the safety of construction workers in high-altitude operations, and can monitor the use of construction workers' safety belts in real time and issue warnings in time to prevent falling accidents caused by the hook position being too low. At the same time, the system ensures that construction workers can quickly detect problems and reduce safety hazards through wireless feedback and timely response of the alarm.

[0055] In other embodiments, the sampling frequency of the air pressure sensor and the sensitivity of the alarm trigger can be adjusted according to different construction heights and environmental conditions. In addition, the alarm prompt method can also be diversified, such as through vibration reminder or combined with portable devices such as smart watches to further enhance the safety protection effect.

[0056] When the construction workers are wearing safety belts and exercising, the difference between the air pressure values ​​received by the cloud platform 10 at the ground end and the main body end is lower than a preset threshold value P T When the alarm is raised, it is judged as entering a safe area, ending the high-hanging and low-use analysis warning state.

[0057] In the above implementation steps, the safety belt body 1 is carried on the operator's back, and products that meet the specifications can be used. The body-side data controller 2 is fixedly installed on the safety belt body 1. The battery contained therein can generally be a polymer lithium battery, the computing unit contained therein can be an STM32 control board, the wireless communication module contained therein is a universal 4G and WIFI module, the alarm contained therein can be a universal ST011 micro sound and light alarm module, the body-side air pressure sensor 3 can be a Bosch BMP280 pressure sensor, which is also installed on the safety belt body 1, and the body data controller 2 reads data and supplies power.

The included wireless communication module is a universal 4G module such as Quectel's EG25-G module; the main body end air pressure sensor 5 is located on the ground end 4, powered by the ground end 4, and controlled by the data controller 6 to read and wirelessly transmit data, wherein the ground end data controller 6 is similar in design to 2, and can read the data from the air pressure sensor 3 at regular intervals, and transmit it to the cloud platform 10 via the mobile Internet; the hook end data controller 7 is similar to 6, and realizes power supply and data reading of the hook end air pressure sensor 8, and wirelessly transmits it to the cloud platform 10; the seat belt hook 9 can be made of products that comply with universal building engineering specifications; the cloud platform 10, based on a universal network platform such as Alibaba Cloud or Tencent Cloud, deploys analysis software based on mobile communication data reception and transmission.
