[0002] The construction industry is a high-risk sector for safety accidents, posing significant risks of personal injury and property damage. Current construction safety monitoring primarily relies on manual inspections or the use of fixed-point surveillance cameras and scattered sensors, which suffers from problems such as blind spots, insufficient real-time performance, subjective recording, difficulties in data integration, and delayed early warnings.

[0003] Especially in complex construction scenarios, such as high-rise building scaffolding, areas with dense large equipment, or deep foundation pit working environments, traditional monitoring methods struggle to capture dynamic changes and are prone to missed detections or misjudgments due to information silos. Even with monitoring equipment installed, long-term manual monitoring or review of recordings is still required, resulting in delayed information acquisition and slow response times.

[0028] Figure 1 This is a structural block diagram of a building construction safety monitoring device based on BIM and IoT, according to an embodiment of this application. Figure 1 As shown, the device includes: a data acquisition unit 11, a processing unit 12, a standardized physical interface 13, and an early warning unit 14.

[0029] The acquisition unit 11 includes at least two different types of sensors 111 for acquiring site environmental data.

[0030] Deploy multiple types of sensors at key monitoring points (such as formwork, scaffolding, large equipment, etc.) to collect environmental data such as displacement, tilt, and vibration in real time.

[0031] The sensors 111 in the acquisition unit 11 include, but are not limited to, infrared sensors, vibration sensors, tilt sensors, strain sensors, displacement sensors, and settlement sensors.

[0032] Vibration sensors can be installed near the location where blasting / piling is required to monitor blasting / piling vibrations, assess the impact of construction vibrations on surrounding buildings and precision instruments, and ensure that they are within safe thresholds. Vibration sensors can also be installed on large structures (such as bridges and tall buildings) to monitor the vibration characteristics of large structures during construction or operation.

[0033] Tilt sensors can be installed on tower cranes, construction elevators, scaffolding, formwork support systems, or deep foundation pit support structures (such as piles and walls) to monitor changes in tilt angle, provide real-time warnings of tilt exceeding limits, and prevent overturning accidents.

[0034] Strain sensors can be installed on critical structural components (such as long-span beams, steel structure nodes, support columns, and temporary supports) to monitor stress and strain states and assess their stress conditions and potential fatigue.

[0035] Displacement / settlement sensors can be installed on the ground surface for settlement / uplift monitoring; they can also be installed on supporting structures (such as diaphragm walls and piles) for structural displacement monitoring (monitoring horizontal displacement and the opening / closing of building cracks); and they can also be installed inside tunnels, large foundation pits, etc., for convergence monitoring (monitoring relative displacement inside tunnels and large foundation pits).

[0036] Infrared sensors can be used for unauthorized entry monitoring, equipment temperature monitoring, and more.

[0037] Before monitoring begins, the placement of each sensor is planned according to the construction drawings and BIM model, and the equipment is installed and calibrated.

[0038] The processing unit 12 is connected to the acquisition unit 11 via a standardized physical interface 13. It is used to receive the site environment data sent by the acquisition unit 11 and obtain the risk analysis results based on the site environment data.

[0039] The standardized physical interface supports flexible access to sensors and devices, adapting to different construction site scenarios.

[0040] In some embodiments, the standardized physical interface 13 employs a housing-sealed design, and / or the surface of the standardized physical interface is coated with a self-drying coating.

[0041] The standardized physical interface features a sealed housing design to meet IP67 protection and is coated with a self-drying coating to prevent poor contact caused by construction site dust / moisture.

[0042] In some embodiments, physical interface standardization 13 includes a multi-protocol compatible socket.

[0043] This embodiment designs a multi-protocol compatible socket (such as an industrial-grade M12 interface), which supports analog signals, digital signals, and wireless pass-through. Preferably, the multi-protocol compatible socket supports analog signals with a transmission standard of 4-20mA / 0-10V, digital signals with a transmission standard of RS-485 / CAN, and wireless pass-through with a reserved slot for LoRa / NB-IoT modules.

[0044] In some embodiments, the processing unit 12 is also connected to a cloud server to send preprocessed data of the construction site environment data and / or the construction site environment data to the cloud server, and to receive risk analysis results returned by the cloud server based on the construction site environment data.

[0045] Based on IoT communication technologies (such as LoRa, NB-IoT, and 5G), a low-power, high-reliability transmission network is built to ensure that data is uploaded to the cloud or local server in real time.

[0046] Optionally, preliminary data filtering and anomaly detection can be performed on terminal devices to reduce cloud load; the cloud can analyze data trends and identify potential risks through AI algorithms (such as machine learning and pattern recognition).

[0047] The processing unit 12 is also connected to the BIM interaction interface 15 for updating the BIM model based on risk analysis results and site environment data through the BIM interaction interface.

[0048] The BIM dynamic interaction interface binds real-time data to the BIM model, enabling automatic updates of BIM model parameters, such as color marking of hazardous areas and 3D dynamic simulation of structural changes.

[0049] In some embodiments, all sensors in the acquisition unit 11 have a built-in unique ID chip, and the device also includes a storage module storing a sensor-component mapping table.

[0050] Each sensor has a built-in unique ID chip with a unique identifier, enabling the sensor to be bound to the ID of the component it monitors. A sensor-component mapping table represents the correspondence between sensors and components, where the constructed ID is its ID in the BIM model. This sensor-component mapping table system automatically maps sensor data streams to the corresponding locations in the BIM model. Sensor data is dynamically bound to BIM component IDs, generating a digital twin of the equipment.

[0051] Continue to refer to Figure 1 The construction safety monitoring device in this application embodiment also includes an early warning unit 14.

[0052] The early warning unit 14 is communicatively connected to the processing unit 12 and is used to provide risk warnings based on the risk analysis results.

[0053] In some embodiments, the warning unit includes an audible and visual alarm for on-site audible and visual warning.

[0054] Optionally, the audible and visual alarm includes a buzzer cavity resonant structure and an LED light guide column layout. When the alarm is triggered, an on-site audible and visual warning is issued via the audible and visual alarm.

[0055] In some embodiments, the early warning unit includes a wireless transmission module for remotely sending early warnings.

[0056] Optionally, when an alert is triggered, the alarm information is automatically pushed to the management personnel via a wireless transmission module (by phone, SMS, or APP notification), and emergency handling suggestions are generated.

[0057] In some embodiments, the device further includes a display screen for showing site environmental data and risk analysis results.

[0058] The display screen shows real-time monitoring data and model status, supporting multi-dimensional views (such as heat maps and trend curves). This display screen includes, but is not limited to, PC screens, mobile screens, or BIM system displays.

[0059] In some embodiments, the device further includes a power supply unit, which is connected to the acquisition unit, the processing unit and the early warning unit respectively. The power supply unit includes a DC-DC power supply module, an Ethernet power supply module and a mode switching component.

[0060] Preferably, the DC-DC power supply module is a wide-voltage input DC-DC module, which has a wide input voltage range, high output voltage regulation accuracy, and supports high current output. The Power over Ethernet (PoE) power supply module transmits power via network cable, eliminating the need for an additional power cord. Intelligent switching between dual modes is achieved through a mode switching component.

[0061] The power supply unit in this embodiment integrates a wide voltage input DC-DC module and Power over Ethernet (PoE) dual modes, automatically identifies the power consumption requirements of sensors, and solves the power supply problem of mixed deployment of multiple types of sensors in complex construction site environments.

[0062] With the aforementioned device, the data acquisition unit, processing unit, and early warning unit automatically monitor construction site safety without human intervention. This upgrades the response time from "hourly" to "second-level" early warning, solving the problems of low efficiency and reliability in construction site safety monitoring and reducing the risk of accidents.

[0063] The standardized physical interface supports flexible access to sensors and devices, adapting to different construction site scenarios.

[0064] Automated early warning and visualization reduce human intervention and improve safety management efficiency.

[0065] By combining the collected IoT dynamic data with the BIM model through BIM interaction interface and ID mapping, the BIM model can be updated in real time, a "digital twin" construction site can be built, and a holographic mapping of the construction status can be achieved.

[0066] It should be noted that for modules / units implemented in hardware, the aforementioned modules / units can reside in the same processor; or the aforementioned modules / units can also reside in different processors in any combination.

[0067] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
