Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a structural safety intelligent monitoring device based on a flower basket type cantilever scaffold. Background Art

[0002] In the construction industry, flower basket-style cantilever scaffolding is a common auxiliary construction facility. Its structural safety is directly related to the safety of construction workers and the overall progress and quality of the project. However, traditional safety monitoring methods mainly rely on manual inspection and empirical judgment, which is inefficient and difficult to detect potential safety hazards in a timely manner. In recent years, with the development of sensing technology and intelligent monitoring systems, some construction sites have begun to experiment with the introduction of equipment such as displacement sensors, infrared sensors, and dynamometers to improve the accuracy and efficiency of monitoring. However, existing technical solutions still have many shortcomings and cannot fully meet the needs of intelligent monitoring of the structural safety of flower basket-style cantilever scaffolding.

[0003] After searching, it was found that an intelligent safety monitoring mining excavation equipment with the publication number CN104989395B was disclosed, and the publication date was April 5, 2017. This patent realizes real-time monitoring of the mining environment and personnel positions by integrating multiple sensors (such as positioning sensors, temperature sensors, current sensors, etc.) and wireless transmission modules, and can quickly locate the position of personnel for search and rescue when an accident occurs. However, this technical solution is mainly aimed at mining excavation equipment, and its application scenarios and monitoring targets are significantly different from those of the flower basket cantilever scaffolding. Specifically, the solution does not involve multi-parameter comprehensive monitoring of key parts of the flower basket cantilever scaffolding (such as cantilever beams and support points), and lacks the ability to evaluate the overall stability of the scaffolding. In addition, its complex wiring system and high installation difficulty limit its applicability in construction sites.

[0004] After searching, a slope safety intelligent monitoring and management system and equipment with publication number CN118816978B was disclosed, and the publication date is July 8, 2025. This patent realizes intelligent monitoring of the safety status of the slope by setting a rainfall monitoring module, a GNSS slope monitoring module and a data processing and control module, and can dynamically adjust the data transmission frequency according to the rainfall. However, this technical solution is mainly used for slope monitoring, and its monitoring parameters (such as rainfall, slope displacement, etc.) are not fully matched with the structural safety requirements of the flower basket cantilever scaffolding. In addition, the solution focuses on parameter monitoring in a single scenario, lacks the ability to comprehensively analyze multi-type sensor data, and it is difficult to comprehensively evaluate the safety of the scaffolding under complex working conditions. At the same time, the design of its early warning mechanism is relatively simple, which cannot meet the needs of the flower basket cantilever scaffolding for multi-level early warning and graded response.

[0005] The above issues indicate that existing intelligent monitoring technologies, when applied to cantilevered flower basket scaffolding, still have certain deficiencies in terms of comprehensive monitoring parameters, intelligent data processing, flexible early warning mechanisms, and convenient installation and deployment. Therefore, the present invention provides an intelligent structural safety monitoring device for cantilevered flower basket scaffolding, designed to achieve real-time multi-parameter monitoring of key scaffolding locations, wireless data transmission, and intelligent early warning capabilities, thereby improving monitoring efficiency, reducing safety hazards, and meeting the demands of modern construction for efficient management and precise control. Summary of the Invention

[0006] The present invention addresses the safety hazards associated with existing cantilever scaffolding, particularly the difficulty in real-time monitoring of load, displacement, and force during installation and use. To address this issue, the present invention employs the following technical solutions: It provides an intelligent structural safety monitoring device based on a cantilever scaffold, comprising a sensor module, an electronic control unit, and a wireless communication network. The sensor module is used to collect load, displacement, and force data from key scaffolding locations; the electronic control unit is used to receive, process, and analyze the data collected by the sensor module and trigger an alarm mechanism based on preset thresholds; and the wireless communication network is used to facilitate data transmission between the modules.

[0007] Furthermore, the sensor module includes a wireless displacement monitoring module and a wireless tension monitoring module. The wireless displacement monitoring module is installed on the scaffolding I-beam end plate and fixed by adsorption via a neodymium magnetic base. The wireless displacement monitoring module uses GIS positioning technology or infrared ranging technology to monitor the scaffolding's displacement in real time. When it detects that the instantaneous displacement exceeds a preset threshold, the wireless displacement monitoring module generates a warning signal and transmits the data back to the central control module via a wireless communication network. Furthermore, the module can monitor the scaffolding's long-term creep and issue an alarm if abnormal creep is detected.

[0008] Specifically, a wireless tension monitoring module is installed at the scaffolding tie rod adjustment device to monitor the stress on multiple tie rods. The wireless tension monitoring module is a modified traditional electronic dynamometer with wireless communication capabilities to enable real-time data transmission. When the wireless tension monitoring module detects that the force on the tie rod exceeds a preset threshold, it generates a warning signal and transmits the data back to the central control module via the wireless communication network. The design of the wireless tension monitoring module enables stable operation in complex construction environments and accurate measurement of tie rod stress.

[0009] Furthermore, the electronic control unit consists of a central control module, a wireless warning module, and other expandable sensors. The central control module serves as the system's data processing center, receiving data from each sensor module and analyzing it according to a preset algorithm. If the central control module determines that a particular monitoring datum exceeds a preset threshold, it sends an alarm command to the wireless warning module via the wireless communication network. Upon receiving the alarm command, the wireless warning module prompts on-site management personnel to take action through an audible and visual alarm device. The audible and visual alarm device includes a speaker and red and blue flashing lights, providing audible and visual warnings, respectively.

[0010] Specifically, the wireless communication network utilizes the ZigBee protocol or 5G mobile networks for both short- and long-distance signal transmission. The ZigBee protocol is suitable for short-distance communication scenarios, offering low power consumption and low cost, making it suitable for flexible deployment on construction sites. The 5G mobile network is ideal for scenarios requiring long-distance communication, ensuring stable and real-time data transmission. Furthermore, all modules support battery or solar panel power supply to accommodate diverse construction scenarios. The solar panel design enables the device to operate outdoors for extended periods, reducing the need for frequent battery replacements.

[0011] Furthermore, the sensor module adopts a modular design and can be configured individually or used in combination according to actual needs. When configured individually, the wireless displacement monitoring module can be used for local monitoring; when two wireless displacement monitoring modules are combined, linear displacement monitoring can be achieved; when four wireless displacement monitoring modules are combined, surface settlement, distortion or local deformation can be monitored. In particular, the bases of all sensor modules are embedded with neodymium magnets for adsorption on the surface of scaffolding materials. The strong magnetic force of the neodymium magnet ensures that the module will not shift during the construction process, thereby ensuring measurement accuracy. In addition, the wireless displacement monitoring module can achieve mutual verification of test results by simultaneously installing GIS positioning sensors and infrared ranging sensors, thereby improving data reliability.

[0012] In particular, the system also includes a data processing and alarm mechanism. S1: Each sensor module collects the load, displacement and force data of the key parts of the scaffolding in real time, and transmits the data back to the central control module through the wireless communication network. S2: The central control module analyzes the received data to determine whether it exceeds the preset threshold. If a certain data exceeds the preset threshold, S3 is executed. S3: The central control module sends an alarm instruction to the wireless warning module through the wireless communication network, triggering the sound and light alarm device to prompt on-site management personnel to take timely measures. The design of the alarm mechanism enables the system to respond quickly when an abnormal situation is detected to avoid accidents.

[0013] The beneficial effects of the present invention are as follows: by installing a variety of sensor modules at key locations of the basket-type cantilever scaffolding and combining it with wireless communication technology, safe and intelligent monitoring of the scaffolding is achieved. First, the load, displacement and stress conditions of the scaffolding are monitored in real time to promptly identify potential safety hazards. Secondly, the early warning system automatically issues an alarm to remind management personnel to take measures to avoid accidents. Furthermore, management personnel can check the status of the scaffolding at any time through the remote monitoring system, reduce the number of on-site inspections, and improve management efficiency. By analyzing the monitoring data, the scaffolding design and construction plan are optimized to improve construction efficiency. In addition, potential problems can be discovered in advance through monitoring data, and preventive maintenance can be carried out to reduce maintenance costs and downtime. Finally, through reasonable use and maintenance, the service life of the scaffolding can be extended and the replacement frequency can be reduced.

[0014] In particular, the present invention improves the flexibility and applicability of the equipment through a modular design. Each sensor module can be configured individually or used in combination according to actual needs to meet the requirements of different construction scenarios. At the same time, the adsorption and fixation method of the neodymium magnetic base simplifies the installation process of the equipment and ensures that the measurement accuracy is not affected by external interference. The choice of wireless communication network takes into account the needs of short-distance and long-distance communication, ensuring the stability and real-time performance of data transmission. In addition, the introduction of solar panels reduces the equipment's dependence on traditional power sources, making it more adaptable in complex construction environments.

[0015] In summary, the present invention significantly improves the safety and management efficiency of the basket-type cantilever scaffolding through intelligent monitoring means, while reducing maintenance costs and extending the service life of the equipment, and has broad application prospects.

[0026] The present invention relates to a structural safety intelligent monitoring device based on a basket-type cantilever scaffold. Figure 1 To the attached Figure 6 Through this embodiment, you can clearly understand the installation, operation principle and operation process of the equipment in actual construction scenes.

[0027] like Figure 1 As shown, the overall structure of the basket-style cantilever scaffolding includes embedded devices 1, I-beams 2, tie rod adjustment devices 3, upper tie rods 4, lower tie rods 5, tie rod-I-beam connection lugs 8, I-beam end plates 9, a main structure 10, and pull rings and latches 11. These components form the basic framework of the scaffolding, and the intelligent monitoring device of the present invention is installed at key locations on this framework to monitor the safety of the scaffolding. Figure 2 The layout of the intelligent monitoring equipment on the scaffolding is shown, where the wireless displacement monitoring module B is installed at the I-beam end plate 9, the wireless tension monitoring module C is installed near the pull rod adjustment device 3, and the central control module MC is set in a position convenient for management personnel to operate.

[0028] The specific installation location and structure of wireless displacement monitoring module B are as follows: Figure 2As shown. The module is fixed to the surface of the I-beam end plate 9 by adsorption through a neodymium magnetic base. The neodymium magnetic base is embedded with a strong magnetic neodymium magnet. Its design ensures that the module will not be offset due to external vibration or impact during the construction process, thereby ensuring measurement accuracy. The wireless displacement monitoring module B uses GIS positioning technology or infrared ranging technology to monitor the displacement of the scaffolding in real time. When the module detects that the instantaneous displacement exceeds the preset threshold, for example, the displacement of the I-beam end plate 9 exceeds 5 mm, the module generates a warning signal and transmits the data back to the central control module MC through the zigbee protocol. In addition, the module can also monitor long-term creep. If it is detected that the cumulative displacement of the I-beam end plate 9 exceeds 10 mm within one month, the alarm mechanism is also triggered. In order to improve data reliability, the module is installed with a GIS positioning sensor and an infrared ranging sensor at the same time. The test results of the two sensors verify each other and the final displacement value is obtained through algorithm calculation.

[0029] The installation position and structure of wireless tension monitoring module C are as follows: Figure 3 As shown. This module is installed at the tie rod adjustment device 3 and is used to monitor the stress conditions of multiple tie rods. The wireless tension monitoring module C is a modified traditional electronic dynamometer with the addition of ZigBee communication function to achieve real-time data transmission. The design of the module enables it to operate stably in complex construction environments and accurately measure the stress conditions of the tie rods. For example, when the stress on the upper tie rod 4 or the lower tie rod 5 exceeds 80% of its designed load-bearing capacity, the module generates a warning signal and transmits the data back to the central control module MC via the wireless communication network. This design ensures real-time monitoring of the stress conditions of the tie rods and avoids structural instability due to uneven stress.

[0030] The module composition and connection relationship of the electronic control part are as follows Figure 4 As shown. The central control module MC serves as the data processing center of the system, receiving data from each sensor module and analyzing the data according to a preset algorithm. When the central control module MC determines that a certain monitoring data exceeds the preset threshold, it sends an alarm instruction to the wireless warning module A through the wireless communication network. After receiving the alarm instruction, the wireless warning module A triggers the sound and light alarm device to prompt the on-site management personnel to take timely measures. The sound and light alarm device includes a speaker and red and blue flashing lights, which are used for sound prompts and visual warnings respectively. For example, when the wireless displacement monitoring module B detects that the displacement of the I-beam end plate 9 exceeds 5 mm, the central control module MC sends an alarm instruction to the wireless warning module A through the zigbee protocol, and the wireless warning module A immediately activates the speaker to sound an alarm and lights up the red and blue flashing lights. This multi-sensory warning method can effectively attract the attention of on-site management personnel and avoid accidents.

[0031] The structure and alarm function of wireless warning device A are as follows Figure 5As shown. The device includes a speaker and red and blue flashing lights, which are installed in easily observable locations on the construction site. Upon receiving an alarm command from the central control module MC, the device immediately activates the alarm function. For example, during a construction process, the wireless tension monitoring module C detects that the force on the lower pull rod 5 exceeds 80% of its designed load-bearing capacity. The central control module MC generates an alarm command and sends it to the wireless warning module A via the ZigBee protocol. The wireless warning module A then activates the speaker to emit a continuous alarm sound and illuminates the red and blue flashing lights. The design of this alarm mechanism enables the system to respond quickly when an abnormal situation is detected, providing on-site managers with ample time to take action.

[0032] Details of the neodymium magnetic base adsorption and fixation are as follows Figure 6 As shown. The bases of all sensor modules are embedded with neodymium magnets for adsorption to the surface of the scaffolding material. The strong magnetic force of the neodymium magnets ensures that the modules will not shift during the construction process, thereby ensuring measurement accuracy. For example, the wireless displacement monitoring module B is fixed to the surface of the I-beam end plate 9 by adsorption through the neodymium magnetic base. Its adsorption force is sufficient to resist the vibration and impact generated during the construction process, ensuring that the module remains stable during long-term use. In addition, the design of the neodymium magnetic base simplifies the installation process of the equipment. The module can be fixed without additional tools, which significantly improves the installation efficiency of the equipment.

[0033] The operating principle and process of the present invention are as follows: S1 Each sensor module collects the load, displacement and force data of the key parts of the scaffolding in real time, and transmits the data back to the central control module MC through the wireless communication network. For example, during the construction process, the wireless displacement monitoring module B uses GIS positioning technology and infrared ranging technology to monitor the displacement of the I-beam end plate 9 in real time, and the wireless tension monitoring module C uses an electronic tension meter to monitor the force of the upper pull rod 4 and the lower pull rod 5 in real time. S2 The central control module MC analyzes the received data to determine whether it exceeds the preset threshold. For example, when the wireless displacement monitoring module B detects that the displacement of the I-beam end plate 9 exceeds 5 mm, or when the wireless tension monitoring module C detects that the force of the lower pull rod 5 exceeds 80% of its designed load-bearing capacity, the central control module MC determines that the data exceeds the preset threshold and executes the next step. S3 The central control module MC sends an alarm instruction to the wireless warning module A through the wireless communication network, triggering the sound and light alarm device to prompt the on-site management personnel to take timely measures. For example, if the central control module MC detects an abnormal force on the lower link 5, it sends an alarm command via the ZigBee protocol to the wireless alarm module A. The wireless alarm module A then activates the horn to sound an alarm and illuminates the red and blue flashing lights. This alarm mechanism enables the system to respond quickly to abnormal conditions and prevent accidents.

[0034] The modular design of the present invention improves the flexibility and applicability of the equipment. For example, the wireless displacement monitoring module B can be configured separately to monitor local displacement according to actual needs, or two modules can be combined to realize linear displacement monitoring, and four modules can be combined to monitor surface settlement, distortion or local deformation. This design enables the equipment to adapt to the needs of different construction scenarios, significantly improving the practicality of the equipment. In addition, the choice of wireless communication network takes into account the needs of short-distance and long-distance communication. For example, within the construction site, the ZigBee protocol is suitable for short-distance communication scenarios, with the characteristics of low power consumption and low cost, and is suitable for flexible deployment; in scenarios requiring long-distance communication, the 5G mobile network ensures the stability and real-time nature of data transmission. The introduction of solar panels further reduces the equipment's dependence on traditional power sources, making it more adaptable in complex construction environments.

[0035] In summary, the present invention significantly improves the safety and management efficiency of the basket-type cantilever scaffolding through intelligent monitoring means. The application of the equipment in actual construction scenarios shows that it can monitor the load, displacement and stress of the scaffolding in real time, promptly detect potential safety hazards and automatically issue an alarm, reminding management personnel to take measures to avoid accidents. In addition, the modular design of the equipment and the choice of wireless communication network enable it to adapt to the needs of different construction scenarios, significantly improving the flexibility and applicability of the equipment. By optimizing the scaffolding design and construction plan through the analysis of monitoring data, not only the construction efficiency is improved, but also the maintenance cost and downtime are reduced through preventive maintenance, and the service life of the equipment is extended, which has broad application prospects.
