Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to an intelligent monitoring and early warning method for safety belts in a construction engineering area. Background Art

[0002] High-altitude operations at construction sites require safety belts to ensure the absolute safety of construction workers and avoid injuries caused by falling. In the real construction environment, construction workers often forget to wear safety belts or fail to use them correctly due to a lack of safety awareness or a fluke mentality. At the same time, construction workers move in complex spaces such as high-altitude building scaffolding, and different positions require more safety protection. Frequent reminders will be counterproductive. Therefore, it is necessary to provide reasonable and effective early warning reminders from a technical perspective to improve safety.

[0003] The industry currently has smart seat belts, such as CN104800988A, which discloses a seat belt that automatically warns when working at heights, and a method for using the same. The seat belt includes an embedded barometer module, an acceleration sensor, a MEMS gyroscope, and a data processing module to judge the movement status of construction workers, remind them to wear seat belts when working at heights, and eliminate work risks. Another example is CN117731976A, which discloses a smart seat belt supervision and early warning platform, which monitors and analyzes the safety status, physical physiological and environmental parameters of workers when working at heights in real time, so as to provide early warning of possible safety incidents. For example, CN201821205586.5 discloses a smart seat belt that can check whether people are wearing standard seat belts. Through the control components, flexible pressure sensors and smart buckles on the seat belt body, the control components include a main control module, a flexible pressure sensor data acquisition module, a smart buckle data acquisition module, a seat belt alarm module and a power module, the use of seat belts for high-altitude workers is checked in real time, reducing the risk factor for high-altitude workers.

[0004] However, the current seat belt warning methods can be summarized as basically only completing the detection of whether the seat belt is worn correctly or high-level warning, and have not yet performed detailed analysis and warning based on the relative spatial position of the construction workers. Unreasonable warnings in the safety area are likely to cause disgust among construction workers and reduce the feasibility of on-site implementation. Therefore, there is still a lack of practical guarantee for the safety and reliability of on-site construction workers. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent monitoring and early warning method for safety belts in construction engineering areas, so as to solve the problem that the prior art does not perform detailed analysis and early warning based on the relative spatial positions of construction personnel, and unreasonable early warnings in safety areas are likely to cause disgust among construction personnel, reducing the feasibility of on-site implementation, and there is still a real lack of safety and reliability assurance for on-site construction personnel.

[0006] To achieve the above object, the present invention provides the following technical solution: an intelligent monitoring and early warning method for safety belts in construction engineering areas, the method comprising:

[0007] S1. Arrange a GNSS satellite positioning device, an air pressure sensor and a data controller in the construction area. The device is divided into a main body end and a hook end. Both the main body end and the hook end are equipped with an air pressure sensor and a data controller, and data transmission is realized through a wireless communication module;

[0008] S2. Place the main body and the hook end at the same elevation before use, and measure and record the initial air pressure values ​​respectively;

[0009] S3. Use the GNSS satellite positioning device on the hook end to locate key points on the edge of the building to form an early warning area on the outer boundary of the building;

[0010] S4. The cloud platform determines the relative position of the construction workers and the height status of the safety belt hook based on the real-time collected satellite positioning data and air pressure data;

[0011] S5. When the construction workers are in the outer boundary area of ​​the building, the high-hanging and low-using judgment is activated, and the pressure difference is used to judge whether the hook is used normally. If the pressure difference exceeds the set range, an early warning signal is triggered;

[0012] S6. The warning signal is transmitted back to the data controller at the safety belt body 1 through the wireless network, triggering an audible and visual alarm to remind the construction personnel.

[0013] Preferably, the data controllers at the main body end and the hook end both include a mobile wireless transmission module and a short-range wireless transmission module based on WIFI.

[0014] Preferably, the outer boundary of the warning area is a set of line segments formed by satellite positioning data of multiple key points on the outer edge of the building scaffolding.

[0015] Preferably, when the construction workers enter the safe area inside the building, the satellite positioning sensor is in a floating point solution or a single point solution state, and automatically stops the high-hanging and low-use judgment and turns off the early warning system.

[0016] Preferably, the cloud platform calculates the height difference between the construction personnel and the hook based on the air pressure data collected in real time by the air pressure sensor, and determines whether to trigger a warning signal.

[0017] Preferably, when the safety belt hook is not used normally or is positioned too low, a warning signal is sent through an audible and visual alarm to alert construction workers and a remote alarm is sent to a management platform.

[0018] Preferably, before using it on site in the construction work area, the main body end and the hook end are placed at the same elevation, and the air pressure value measured by the air pressure sensor at the main body end is recorded as P m0 ; The air pressure value P measured by the air pressure sensor at the hook end h0 , transmitted wirelessly to the network cloud platform, the P h0 The values ​​are forwarded by the data controller via WIFI.

[0019] Preferably, the hook-end satellite positioning sensor is used to locate key points in the outer edge area of ​​the construction work, and the data P0, P1, ..., Pn are recorded to form a line segment set as the outer boundary of the warning area.

[0020] Preferably, when the cloud platform system is started, the initial state is calculated and recorded. The satellite analysis state and position data Pt obtained by the satellite positioning sensor are recorded in real time. When the construction personnel wear safety belts during work, the satellite positioning sensor is in a fixed state, and the judgment sequence is used to determine whether the position of Pt is within a 2-meter range around the line segment composed of P0, P1, ..., Pn, etc. If it is within this range, the high hanging and low use judgment is started;

[0021] If the satellite positioning sensor 4 is in a floating point solution or single point solution state, it is judged as entering the safe area inside the building, and the high-hanging and low-using judgment is disabled.

[0022] Preferably, when the high hanging and low use judgment is started, the cloud platform analyzes the received real-time air pressure data:

[0023] When (P h -P h0 )-(P m -P m0 )>P dif When the hook is used normally, a safety signal is sent back.

[0024] 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;

[0025] The cloud platform wirelessly transmits data back to the data controller at the seat belt body, which activates the alarm according to the warning status and provides a portable sound and light alarm reminder.

[0026] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0027] The intelligent monitoring and early warning method for safety belts in construction engineering areas places the main body end and the hook end at the same elevation before use, measures and records the initial air pressure value respectively, and the cloud platform judges the relative position of the construction personnel and the height state of the safety belt hook according to the satellite positioning data and air pressure data collected in real time. When the construction personnel are in the outer boundary area of ​​the building, the high hanging and low use judgment is started, and the air pressure difference is used to judge whether the hook is used normally. If the air pressure difference exceeds the set range, the early warning signal is triggered, and the early warning signal is transmitted back to the data controller at the safety belt main body 1 end through the wireless network, and the sound and light alarm is triggered to remind the construction personnel. The influence of weather changes on the air pressure at the construction site is taken into account, and the use state of the safety belt hook of the construction personnel in the high-altitude complex working environment is judged more accurately and in real time. The working state of the on-site personnel can be quickly grasped to provide a basis for the management department, and the early warning signal can be provided in real time, so as to more fully ensure the safety of the personnel working at high altitude. The problem that the existing technology does not perform fine analysis and early warning based on the relative spatial position of the construction personnel, and the unreasonable early warning in the safety area is easy to cause the disgust of the construction personnel, reduces the feasibility of on-site implementation, and still has the problem of lack of reality in terms of the safety and reliability guarantee of the on-site construction personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[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] As shown in the figure, a method for intelligent monitoring and early warning of safety belts in construction engineering areas includes the following steps:

[0031] S1. GNSS satellite positioning devices, air pressure sensors and data controllers are arranged in the construction area. The equipment is divided into the main body and the hook end. Both the main body and the hook end are equipped with air pressure sensors and data controllers, and data transmission is achieved through wireless communication modules.

[0032] S2. Before use, place the main body and the hook end at the same elevation, and measure and record the initial air pressure respectively.

[0033] S3. Use the GNSS satellite positioning device on the hook end to locate the key points on the edge of the building and generate an early warning area on the outer boundary of the building.

[0034] S4. Through the cloud platform, based on the real-time collected satellite positioning data and air pressure data, the location of the construction workers and the height status of the safety belt hook are determined.

[0035] S5. When construction workers are located in the outer boundary area of ​​the building, the "high hanging and low use" judgment is activated, and the air pressure difference is used to determine whether the hook is used normally; if the air pressure difference exceeds the set range, an early warning signal is triggered.

[0036] S6. The warning signal is transmitted back to the data controller at the safety belt body 1 through the wireless network, triggering an audible and visual alarm to remind the construction personnel.

[0037] This method uses GNSS satellite positioning and air pressure sensing technology, combined with wireless communication modules, to intelligently monitor construction workers and the safety belts they use. The system determines whether the hook position of the safety belt is correct by measuring the air pressure difference, and determines whether the construction workers have entered the danger zone based on satellite positioning data. When an abnormal state is detected, the system will automatically trigger an audible and visual alarm to remind construction workers to adjust the use of the safety belt in time to ensure safety.

[0038] The present invention can effectively prevent construction workers from falling due to improper use of the safety belt hook. Through the combination of air pressure sensing and satellite positioning technology, the system can accurately determine the area where the construction workers are located and the use of the safety belt, greatly improving the safety of the construction site. At the same time, the system's automated early warning mechanism can respond quickly, improve construction efficiency, and reduce labor costs.

[0039] In other embodiments, the air pressure sensor and the satellite positioning device can be selected in different models according to different construction environments, and the accuracy of the data can be improved by expanding the number of sensors. At the same time, the wireless communication module can adopt different wireless transmission protocols, such as 5G or LoRa, to adapt to different network environments.

[0040] In a possible implementation, the data controllers at the main body end and the hook end both include a mobile wireless transmission module and a short-range wireless transmission module based on WI FI. The mobile wireless transmission module is used for long-distance communication, while the WI FI module is used for short-range rapid data exchange. The data controller communicates with the cloud platform through the mobile wireless transmission module to ensure that the status of the construction personnel and the safety belts can be uploaded to the cloud platform in real time for processing. At the same time, the WI FI module is used for short-range data transmission between the main body end and the hook end, so that the air pressure sensor and the satellite positioning device can quickly synchronize data to ensure the system is responsive. The design of this dual transmission module can not only ensure the stability of long-distance data transmission, but also realize the rapid exchange of local data, ensuring the response speed and accuracy of the entire monitoring system. Especially in the construction of high-rise buildings, the mobile wireless transmission module can ensure wide signal coverage, while the WI FI module improves the efficiency of data transmission between devices.

[0041] In other embodiments, the transmission module of the data controller can select different communication protocols according to the construction environment, such as short-distance transmission via Bluetooth, or long-distance data transmission via satellite communication, to adapt to special terrain or network environment.

[0042] In a possible implementation, the outer boundary of the warning area is a set of line segments formed by satellite positioning data of multiple key points on the outer edge of the building scaffolding. These key points are acquired and recorded by a GNSS satellite positioning device to form a complete warning area. By performing GNSS positioning at key positions on the outer edge of the building scaffolding, the external boundary information of the building can be obtained. The positioning data of each key point constitutes a set of line segments to form a complete warning area, which is used to determine whether the construction personnel have entered the danger zone. The definition of the warning area ensures that when the construction personnel approach the edge of the building, the system can issue an alarm in time. This method can accurately define the outer boundary area of ​​the building, ensuring that when the construction personnel approach the danger zone, the system can trigger an alarm in time to prevent accidental falls. By using GNSS technology to obtain key point data of the outer boundary of the building, the warning area can be dynamically adjusted to adapt to the construction environment of different building structures.

[0043] In other embodiments, the key point data of the building outer boundary can be obtained by other means, such as measuring and drawing the boundary by laser ranging equipment. At the same time, the shape of the warning area can be adjusted according to the actual form of the building, and is not limited to the form of a line segment set.

[0044] In one possible implementation, when construction workers enter the internal safety area of ​​the building, the satellite positioning sensor is in a floating point solution or single point solution state, and the system automatically stops the high-hanging and low-use judgment and turns off the early warning system. When construction workers enter the internal safety area from outside the building, the satellite positioning sensor can no longer obtain high-precision positioning data due to signal blocking, and enters a floating point solution or single point solution state. At this time, the system will automatically determine that the construction workers are in a safe area, stop monitoring the hook, turn off the early warning system, and avoid the occurrence of false alarms. This method can intelligently identify the working area of ​​the construction workers and dynamically adjust the working state of the monitoring system according to the different areas, avoiding unnecessary triggering of early warning signals and reducing interference with construction workers. At the same time, the system can intelligently judge the safety status when entering the interior of the building, further improving the safety and comfort of construction.

[0045] In other embodiments, the system can identify the internal area of ​​the building by other means, such as by installing internal sensors or combining architectural drawing data to divide the area. In addition, the system can add a manual mode, when the construction workers enter the safe area, they can manually turn off the early warning system to further optimize the user experience.

[0046] In one possible implementation, the cloud platform calculates the height difference between the construction workers and the hook based on the air pressure data collected in real time by the air pressure sensor, and determines whether to trigger an early warning signal. The system collects air pressure data from the main body and the hook end, and analyzes the height difference between the two in real time. The air pressure sensor detects the air pressure data from the main body (the part of the safety belt worn by the construction workers) and the hook end, and uses the relationship between air pressure and height to calculate the height difference between the two. If the height difference exceeds the safe range, the system believes that the hook position is too low or not used correctly, and triggers an early warning signal. If the air pressure difference is within the set range, the system believes that the hook is used normally and maintains a safe state. Through real-time collection and analysis of air pressure data, the system can accurately determine the height difference between the construction workers and the hook, and ensure that the hook is in the correct height position. This method improves the standardization of the use of safety belt hooks, reduces safety hazards in high-altitude operations, and reduces human errors through automated monitoring.

[0047] In other embodiments, the system may add multiple air pressure sensors to improve the accuracy of the data. At the same time, the system may also combine other sensors (such as acceleration sensors) to assist in determining whether the hook is in a suitable working position and trigger different levels of alarms when the hook is not in use.

[0048] In a possible implementation, when the safety belt hook is not used normally or is too low, the warning signal reminds the construction personnel through the sound and light alarm, and sends a remote alarm to the management platform. The management platform can monitor the safety status of multiple construction sites in real time, and receive the warning signals of each construction site through the network. When the air pressure sensor detects that the hook is too low or not used normally, the system automatically triggers the sound and light alarm, and reminds the construction personnel to adjust the hook in time through sound and light. At the same time, the system will send a remote alarm to the management platform through the wireless communication module to remind the site supervisor or the person in charge of safety to take further action. The management platform can centrally monitor the status of all construction personnel and record all alarm information. Through the real-time reminder of the sound and light alarm, the construction personnel can quickly learn about the improper use of the hook and make adjustments in time to avoid safety accidents. At the same time, the remote alarm function enables managers to remotely grasp the safety status of the construction site, improve the efficiency and timeliness of construction safety management, and further ensure the safety of construction personnel.

[0049] In other embodiments, the alarm form can be diversified, such as adding vibration reminders or voice warnings. In addition, the system can integrate video monitoring functions, and the management platform can view the on-site status of construction workers in real time to more intuitively judge the safety status.

[0050] In a possible implementation, before using it on site in a construction work area, the body end and the hook end are placed at the same elevation to measure the initial value of the air pressure sensor. The air pressure value measured by the air pressure sensor at the body end is recorded as P m0 , the air pressure value measured by the air pressure sensor at the hook end is recorded as P h0 All data are transmitted to the cloud platform wirelessly, and the air pressure value P m0 and P h0 The WIFI module forwards the data to the system platform through the data controller. Before construction, the air pressure sensors on the main body and the hook are placed at the same elevation to measure and record the initial air pressure value. This can provide a reference value for the subsequent height difference calculation. The system uploads the initial air pressure data to the cloud platform via the wireless network so that real-time air pressure difference calculation and hook height monitoring can be performed during the construction process. Through the calibration of the initial air pressure value, the system can more accurately calculate the height difference between the main body and the hook during the construction process, ensuring more accurate monitoring of the hook position. The use of the WIFI module improves the efficiency of data transmission, ensures that the system can quickly collect and upload data in the field environment, and reduces errors in the initialization process.

[0051] In other embodiments, the calibration process of the initial air pressure value can be combined with a laser ranging device for double calibration to further improve the accuracy of the air pressure data. At the same time, the initial air pressure value can also be dynamically adjusted according to the climate change of the construction environment, such as by real-time correction through an environmental sensor.

[0052] In a possible implementation, the satellite positioning sensor at the hook end is used to locate key points in the outer edge area of ​​the construction work, record multiple data points P0, P1,..., Pn, and form a line segment set as the outer boundary of the warning area. The GNSS satellite positioning device at the hook end is used to locate the key points on the outer edge of the construction work area, and record the satellite positioning data of these key points to form a line segment set. The line segment set is used as the outer boundary of the warning area. During the construction process, the system continuously monitors the position of the construction personnel to determine whether they are close to the dangerous area. Through the satellite positioning data, the system can accurately record multiple key points on the outer edge of the construction work to form a dynamic warning area boundary. When the construction personnel approach the warning area, the system can issue a warning in time to prevent the construction personnel from mistakenly entering the dangerous area. This method improves the accuracy of monitoring and makes the early warning system more sensitive and accurate.

[0053] In other embodiments, the boundary of the warning area can be demarcated by other technical means, such as laser scanning or drone survey. In addition, the recording of key point data can be combined with multiple sensors so that the outer boundary data can still be accurately obtained under different weather or signal conditions.

[0054] In a possible implementation, when the cloud platform system is started, the initial state is recorded, and the satellite analysis state and position data obtained by the satellite positioning sensor are recorded in real time. When the construction workers wear safety belts, the satellite positioning sensor is in a fixed solution state, and the system determines whether its position is within a 2-meter range around the line segment set; if it is within this range, the system starts the "high hanging and low use" judgment. If the satellite positioning sensor is in a floating point solution or a single point solution state, it is determined that the construction workers have entered the internal safety area of ​​the building, and the high hanging and low use judgment is stopped.

[0055] When the system starts, the initial state of the satellite positioning sensor is first recorded. During the construction process, if the satellite positioning sensor is in a fixed solution state, the system will determine whether the construction personnel are close to the warning area based on the positioning data. If the construction personnel are within 2 meters of the outer boundary, the system will start the high hanging and low use judgment to monitor the hook position. If the positioning sensor enters the floating point solution or single point solution state, the system determines that the construction personnel are in a safe area inside the building and automatically stops the hook monitoring. This implementation method uses precise satellite positioning technology to ensure that the hook position monitoring is started in time when the construction personnel approach the dangerous area to avoid accidents. The system can automatically identify the safe area where the construction personnel are located, and adjust the monitoring method according to the status of different areas, reduce unnecessary alarm triggering, and improve the safety and management efficiency of the construction site.

[0056] In other embodiments, the monitoring accuracy of the early warning area can be optimized by adding multiple satellite positioning sensors or using differential GPS technology. In addition, the system can be combined with the building structure diagram to achieve a more detailed internal and external area division, further improving the intelligent level of security monitoring.

[0057] When the high-hang-low-use judgment is activated, the cloud platform analyzes the received real-time air pressure data:

[0058] When (P h -P h0 )-(P m -P m0 )>P dif When the hook is used normally, a safety signal is sent back.

[0059] 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;

[0060] The cloud platform wirelessly transmits data back to the data controller at the seat belt body 1, activates the alarm according to the warning status, and issues a portable sound and light alarm reminder.

[0061] The system determines whether the hook is in the proper position by analyzing the air pressure difference between the main body and the hook in real time. When the difference between the air pressure value Ph at the hook end and the initial value Ph0, and the air pressure value Pm at the main body and the initial value Pm0 exceeds the preset threshold value Pdif, the system determines that the hook is in normal use and returns a safety signal. If the difference does not reach the threshold, the system considers that the hook is too low, issues a warning signal, and wirelessly transmits the alarm signal back to the main body of the safety belt, activating an audible and visual alarm reminder. Through automated air pressure difference analysis, the system can accurately determine the use status of the hook to ensure the safety of construction workers. Real-time warning signals can promptly remind construction workers to adjust the hook position to avoid falling accidents. In addition, the system can respond quickly and provide accurate feedback on the hook status, reducing the need for manual intervention.

[0062] In other embodiments, the threshold of Pd if can be adjusted according to different construction heights or working conditions to adapt to a wider range of application scenarios. The system can also integrate more sensors to further optimize the accuracy of data analysis and improve the flexibility of safety monitoring.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
