Description

Technical Field

[0001] The present application relates to the technical field of construction supervision, and in particular to a safe and intelligent supervision system for construction sites. Background Art

[0002] With the acceleration of urbanization, the scale of construction sites continues to expand and the construction environment becomes increasingly complex. Traditional safety management models can no longer meet the modern construction site's requirements for efficiency, real-time performance, and intelligence.

[0003] Currently, construction site safety management faces the following major technical bottlenecks: 1. Inadequate electricity safety supervision: Traditional power distribution systems rely on manual inspections, unable to monitor circuit conditions (such as leakage, overload, and arc faults) in real time. Fault response is delayed, easily leading to fires or electric shock accidents. 2. Video surveillance blind spots: Fixed monitoring equipment requires stable power and network support, making it difficult to cover temporary construction areas, foundation pits, and other short-term work areas, leading to safety oversight gaps. Traditional solutions rely on rotating human staff, which is inefficient and unable to provide round-the-clock intelligent identification (such as illegal operations and personnel trespassing). 3. Limited protection measures for high-voltage power lines: Construction sites near high-voltage power lines often use physical fencing or warning signs, which provide poor nighttime visibility and prevent dynamic detection of mechanical intrusion risks. Furthermore, it is difficult to accurately locate the intrusion point and trigger a multi-level response. 4. Data silos and lack of coordination: Power, monitoring, and protection systems operate independently, preventing data from being integrated and analyzed, making it difficult to predict safety hazards in a timely manner.

[0004] To address the above issues, existing technologies have attempted to optimize through single function improvements (such as upgrading sensors or increasing the number of cameras), but have failed to build a multi-dimensional intelligent system covering power consumption, monitoring, and high-voltage protection, nor have they achieved intelligent collaboration between devices and data-driven active protection.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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 making creative efforts are within the scope of protection of the present invention.

[0020] The following description of some of the technologies involved in the embodiments of this application is provided to facilitate understanding and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for the sake of clarity and conciseness, some descriptions of well-known functions and structures are omitted from the following description.

[0021] Figure 1 This is a structural diagram of a construction site safety intelligent supervision system provided in an embodiment of the present application, including a communication-connected cloud platform, an intelligent power management module, a violation supervision module and a high-voltage line intelligent protection module.

[0022] In an embodiment of the present application, the smart electricity management module is configured to: dynamically monitor the electricity consumption data of the construction site and upload the electricity consumption data to the cloud platform in real time; perform anomaly detection and anomaly location based on the electricity consumption data, and send the results of the anomaly location to the violation supervision module; cut off the circuit of the affected area based on the results of the anomaly location; cut off the corresponding circuit based on the intrusion information of the high-voltage line intelligent protection module; and remotely control the electricity consumption of equipment at the construction site; wherein the electricity consumption data includes the voltage, current, power and operating temperature of the construction site.

[0023] like Figure 2As shown, in an embodiment of the present application, the smart power management module includes a data detection unit, an intelligent molded case circuit breaker arranged in a secondary distribution box, and an intelligent micro-breaker device arranged in a tertiary distribution box; the intelligent molded case circuit breaker is used to: collect power consumption data in the secondary circuit in real time, and send the power consumption data in the secondary circuit to the cloud platform and the data detection unit; cut off the power supply when the circuit is overloaded or short-circuited; cut off the corresponding circuit based on the result of abnormal positioning; cut off the power supply of the corresponding circuit in response to remote control; cut off the corresponding circuit according to the intrusion information of the high-voltage line intelligent protection module; the smart micro-breaker device is used to: collect power consumption data in the tertiary circuit in real time, and send the power consumption data in the tertiary circuit to the cloud platform and the data detection unit; cut off the power supply when the circuit is overloaded or short-circuited; cut off the corresponding circuit based on the result of abnormal positioning; cut off the power supply of the corresponding circuit in response to remote control; the data detection unit is used to perform abnormality detection and abnormality positioning based on the power consumption data of the secondary circuit and the power consumption data of the tertiary circuit, and send the result of abnormal positioning to the smart molded case circuit breaker and / or the smart micro-breaker device, and the violation supervision module.

[0024] Specifically, the smart electricity management module is connected to the violation supervision module and the cloud platform through the first communication unit. The smart molded case circuit breaker is installed in the secondary distribution box and has functions such as overload, short circuit, phase loss, overvoltage, undervoltage, and residual current action protection, which can protect the circuit and electrical equipment from damage. The smart molded case circuit breaker can collect power consumption data such as voltage, current, leakage current, active power, reactive power, power factor, operating temperature, and power in real time. The smart micro-breaker device is smaller than the traditional circuit breaker and can be installed in the three-level distribution box, saving space and installation costs. It can monitor the current, voltage, power, operating temperature and other power consumption data in the circuit in real time.

[0025] It's important to note that the operating temperature here refers to the temperature of the tertiary or secondary circuits during operation. In this application, the secondary distribution box is located in the middle of the power distribution at the construction site (the main line within a building or area), and the tertiary distribution box is located at the end of the power distribution at the construction site (i.e., at the specific electrical equipment).

[0026] In an embodiment of the present application, the data detection unit determines the data with abnormal fluctuations based on the received power consumption data of the secondary circuit and the power consumption data of the tertiary circuit, combined with historical data, to determine the anomaly. The data detection unit can also perform consistency analysis. If the sum of the currents of the branches is not equal to the total current, it indicates that there is leakage or power theft in the circuit. The data detection unit then locates the anomaly based on the determined anomaly. If the current of the secondary circuit is abnormal, the main line is checked first. If the current of the branch circuit is abnormal, it is located in a specific tertiary circuit. In addition, the present application can also combine with a device fingerprint library (such as the harmonic characteristics when the motor starts) to identify the specific faulty device.

[0027] Furthermore, after locating the anomaly, the data detection unit sends a trip command to the intelligent molded case circuit breaker (controlling the secondary circuit) or the smart micro-breaker (controlling the tertiary circuit), disconnecting the corresponding circuit. For example, this application prioritizes disconnecting the tertiary circuit to avoid expanding the power outage and affecting construction progress.

[0028] It should be noted that if the abnormality here is a minor abnormality (such as overload, overvoltage, undervoltage, etc.), the smart molded case circuit breaker and the smart micro-breaker device can adjust themselves without the need to cut off the power through the data detection unit.

[0029] In an embodiment of the present application, the high-voltage line intelligent protection module is configured to: communicate with multiple groups of laser warning devices set along the high-voltage line, issue an audible and visual alarm when an object is detected intruding into the warning area, and send the intrusion information to the cloud platform and the violation supervision module; detect the status of the grounding resistance in real time to prevent step voltage accidents.

[0030] In the embodiments of this application, Figure 5 As shown, the high-voltage line intelligent protection module includes a sensing unit and a monitoring unit; the sensing unit is communicatively connected to multiple groups of laser warning devices arranged along the high-voltage line; wherein, the multiple groups of laser warning devices form a partitioned and linked laser warning network in the warning area of ​​the high-voltage line, and trigger an audible and visual alarm when an object is detected intruding into the warning area, and send the intrusion information containing positioning information to the sensing unit; after receiving the intrusion information, the sensing unit synchronously performs an audible and visual alarm, and sends the intrusion information to the cloud platform; when the duration of the audible and visual alarm of the sensing unit reaches a preset duration, the intrusion information containing positioning information is communicated and sent to the violation supervision module, so that the violation supervision module can track the intrusion target at the coordinate location; the monitoring unit is communicatively connected to multiple ground resistance testers deployed at the test points of the high-voltage line, for obtaining the resistance values ​​of multiple test points, and performing an audible and visual alarm when the resistance value of the test point is abnormal.

[0031] Among them, the laser warning device includes a green laser transmitter and a photosensitive receiver; the green laser transmitter is used to emit a green laser beam; the photosensitive receiver is used to receive the green laser beam from the green laser transmitter, convert the received green laser beam into an electrical signal, and send the electrical signal to the sensing unit.

[0032] The zone-linked laser warning network consists of multiple independent detection sections. Each detection section is equipped with an independent alarm host. The positioning information of each detection section is pre-determined and stored in the corresponding alarm host. The alarm hosts of each detection section are connected through the LoRa wireless network. When the sound and light alarm is triggered, the alarm host will simultaneously push intrusion information containing positioning information to the sensing unit.

[0033] Specifically, this application uses a green laser transmitter and a photosensitive receiver to form a laser warning device. Multiple sets of laser warning devices are installed along high-voltage lines to form a zoned, coordinated laser warning network. This zoned, coordinated laser warning network consists of multiple independent detection segments. The alarm host in each detection segment is wirelessly connected via LoRa (a low-power wide area network communication technology that enables low-power data transmission over long distances). When the alarm host triggers an audible and visual alarm, it simultaneously pushes intrusion information containing positioning information to the sensing unit. Upon receiving the intrusion information, the sensing unit simultaneously issues an audible and visual alarm to attract the attention of management personnel.

[0034] In an embodiment of the present application, the smart electricity management module also includes an abnormal alarm unit; the abnormal alarm unit issues an audible and visual alarm based on the result of the secondary confirmation of the violation supervision module, and sends the result of the secondary confirmation to the cloud platform.

[0035] In an embodiment of the present application, the violation supervision module is configured to: obtain environmental information and personnel data within the construction site; detect whether the construction site meets the construction regulations based on the obtained environmental information to obtain environmental monitoring results; perform face detection, safety equipment detection and dangerous behavior detection through the obtained personnel data to obtain personnel detection results; issue sound and light alarms for unqualified information in the environmental monitoring results and personnel detection results; perform target tracking on the abnormal positioning results of the smart power management module and the intrusion information of the high-voltage line intelligent protection module to obtain tracking information.

[0036] In the embodiments of this application, Figure 4 As shown, the violation supervision module includes an AI electronic sentry unit; the AI ​​electronic sentry unit is configured to: communicate with multiple AI electronic mobile sentries; use multiple AI electronic mobile sentries to inspect the construction site and obtain environmental information and personnel data in the construction site; issue sound and light alarms based on the received unqualified information; send environmental information, personnel data and tracking information to the cloud platform; among which, environmental information includes smoke, ambient temperature, humidity, noise and vibration; personnel data includes facial information, clothing information and body information of personnel in the construction site.

[0037] In addition, when the AI ​​electronic sentry unit issues an audible and visual alarm, it flashes lights of different colors according to the severity of the unqualified information and announces the unqualified behavior by voice.

[0038] In addition, the AI ​​electronic sentry unit is communicated with the smart power management module and receives the results of the abnormal positioning of the smart power management module; controls the AI ​​electronic mobile sentry to track the abnormality at the location according to the results of the abnormal positioning, and sends the tracking information collected by the tracking to the abnormality analysis unit; receives the intrusion information of the high-voltage line intelligent protection module; controls the AI ​​electronic mobile sentry to track the location of the positioning information according to the positioning information in the intrusion information, and sends the tracking information collected by the tracking to the abnormality analysis unit.

[0039] Specifically, after the data detection unit in the smart power management module detects and locates anomalies, it sends the results of the anomaly location to the violation monitoring module. The AI ​​electronic sentry unit in the violation monitoring module then controls an AI electronic mobile sentry near the location of the anomaly location to track the anomaly and collect tracking information. This tracking information is then sent to the anomaly analysis unit for analysis and secondary confirmation, which is then sent to the smart power management module or the high-voltage line intelligent protection module. The AI ​​electronic mobile sentry is equipped with an infrared camera and a normal camera, capable of identifying serious anomalies in the circuit, such as circuit overheating, equipment overheating, and fire.

[0040] In an embodiment of the present application, the violation supervision module also includes an analysis and processing unit, a detection unit, and an anomaly analysis unit that are communicatively connected to the AI ​​electronic sentinel unit.

[0041] The analysis and processing unit is used to: conduct construction inspections on smoke, vibration, and noise at the construction site based on the received environmental information to determine whether government construction regulations are met, and conduct environmental inspections on the construction site based on the ambient temperature and humidity to determine whether it is suitable for construction; obtain environmental monitoring results based on the results of construction inspections and environmental inspections, and send unqualified information in the environmental monitoring results to the AI ​​electronic sentry unit.

[0042] The detection unit is used to: compare the received facial information with the pre-entered employee information to screen out unknown personnel, perform dress code detection based on the received clothing information to screen out employees with irregular clothing, and perform dangerous behavior analysis based on body information to screen out dangerous behaviors; obtain personnel monitoring results based on the results of facial information comparison, dress code detection and dangerous behavior analysis, and send unqualified information in the personnel monitoring results to the AI ​​electronic sentry unit.

[0043] The abnormality analysis unit is configured to analyze and reconfirm the tracking information collected by the AI ​​electronic mobile sentinel unit, and send the results of the reconfirmation to the smart power management module or the high-voltage line intelligent protection module.

[0044] Specifically, the analysis and processing unit compares received construction site environmental information with government regulations on smoke, vibration, and noise at construction sites to determine whether the construction site complies with government construction regulations. If regulations are exceeded, the unit sends the infraction information (i.e., non-compliance information) to the violation monitoring module. The AI ​​electronic sentinel unit in the violation monitoring module issues an audible and visual alarm, allowing on-site personnel to make timely adjustments to ensure that construction operations at the construction site comply with government regulations. The analysis and processing unit can also determine the suitability of the construction site based on ambient temperature and humidity. For example, high temperatures can cause workers to become dehydrated or suffer from heatstroke. High temperatures can also accelerate the setting of concrete, affecting its strength. Low temperatures can cause frostbite, hindering operator flexibility and posing a safety hazard. Furthermore, low temperatures prevent construction materials such as concrete and paint from setting or drying properly. High humidity can cause metal to rust, wood to expand, and concrete to cure slowly. Low humidity can cause wood to crack, concrete to lose water too quickly, affecting its strength, and may also increase the risk of static electricity. To ensure personnel safety and construction quality during the construction process, it is necessary to monitor the ambient temperature and humidity. When the ambient temperature and humidity exceed the set range (the ambient temperature setting range is 3 degrees to 38 degrees, and the humidity setting range is 15% to 85%), it is considered unqualified and sent to the violation supervision module. The AI ​​electronic sentry unit in the violation supervision module will issue an audible and visual alarm.

[0045] Furthermore, the detection unit is used to identify the features of each face in the facial information collected by the AI ​​electronic sentry unit, and compare it with the pre-entered employee information to screen out unknown personnel in the construction site, and send the information of the unknown personnel (i.e., unqualified information) to the violation supervision module, and perform sound and light alarms through the AI ​​electronic sentry unit in the violation supervision module. In addition, the monitoring unit and the AI ​​electronic sentry unit can also be used in combination to perform personnel sign-in accounting in this application. The detection unit can also perform dress code detection (whether wearing a safety helmet, whether wearing work clothes) based on the received dress information to screen out employees who are not dressed properly, and send relevant information of employees who are not dressed properly to the violation supervision module, and perform sound and light alarms through the AI ​​electronic sentry unit in the violation supervision module. The detection unit can also perform dangerous behavior analysis based on body information, and send the analyzed dangerous behavior information to the violation supervision module, and perform sound and light alarms through the AI ​​electronic sentry unit in the violation supervision module.

[0046] like Figure 3As shown, in an embodiment of the present application, the AI ​​electronic sentry unit includes a pan-tilt control unit, a communication unit and a violation alarm unit; the pan-tilt control unit is used to control the direction and angle of the camera installed on the AI ​​electronic mobile sentry to achieve tracking of specific targets; the communication unit is connected to multiple AI electronic mobile sentries to obtain environmental information and personnel data within the construction site; wherein, the AI ​​electronic mobile sentry is equipped with a variety of sensors, infrared cameras and normal light cameras; the violation alarm unit is used to issue sound and light alarms based on the received unqualified information.

[0047] Specifically, the gimbal control unit first identifies the target to be tracked in the first frame or specified frame of the video captured by the AI ​​electronic mobile sentry, identifies and learns the features in the target, and uses the target tracking algorithm (Kernelized Correlation Filters, or, Multiple Object Tracking, multi-target tracking algorithm) to predict the target's position in the next frame. Based on the predicted target position, the control signal is sent to the gimbal. The gimbal then drives the camera installed on the AI ​​electronic mobile sentry to adjust the direction and angle of the camera to keep the target in the center of the field of view to achieve target tracking.

[0048] Those skilled in the art should realize that the above-mentioned method of target recognition, target position prediction and control of the gimbal to track the target implemented in the gimbal control unit is only an embodiment of the present application and does not limit the scope of protection of the present application. Those skilled in the art may also adopt other methods as long as they can achieve tracking of specific targets by controlling the direction and angle of the camera.

[0049] In the embodiments of the present application, the AI ​​electronic mobile sentry is an intelligent monitoring device that is easy to move. It is equipped with rollers on the bottom to facilitate manual pushing to the appropriate position, but it cannot move autonomously. The AI ​​electronic mobile sentry is equipped with solar panels and batteries and does not need to be plugged in. Multiple AI electronic mobile sentries are set up in the construction site. The parking position of each AI electronic mobile sentry can be manually determined according to the importance of the area, or it can be evenly arranged according to the monitoring range of the AI ​​electronic mobile sentry so that it can cover the entire construction site. In addition, the AI ​​electronic mobile sentry is equipped with multiple sensors (for example: temperature sensor, humidity sensor, noise sensor, vibration sensor, position sensor, etc.), infrared camera and normal light camera. Ambient temperature, humidity, noise and vibration are obtained through various sensors.

[0050] Infrared cameras capture infrared images of the construction site, while normal light cameras capture normal light images. Infrared images can monitor temperature changes at the construction site, promptly identifying potential fire hazards or other safety issues caused by temperature fluctuations. They can also identify the distribution and movement of smoke within the construction site, locating fire sources and verifying construction compliance (e.g., ensuring smoke generated during construction is below government standards).

[0051] In an embodiment of the present application, the cloud platform is configured to: receive on-site information consisting of electricity consumption data, environmental information, personnel data, tracking information and intrusion information, and store the on-site information in the cloud; predict high-frequency violation areas and analyze electricity consumption based on the on-site information; and establish a linkage model based on the on-site information to support data decision-making.

[0052] In the embodiments of this application, Figure 6 As shown, the cloud platform includes a data integration unit, a spatiotemporal modeling unit and an intelligent analysis unit; the data integration unit is used to integrate on-site information and establish a time series database for storage; the spatiotemporal modeling unit is used to establish a three-dimensional coordinate system and multiple three-dimensional models of the construction site, bind the on-site information received by the cloud platform with the corresponding three-dimensional model, and map it to the three-dimensional coordinate system of the construction site to form a linkage model; the intelligent analysis unit is used to perform intelligent analysis of the on-site information according to the linkage model, determine the high-frequency violation areas therein, and predict new high-frequency violation areas based on the analyzed high-frequency violation areas; and the electricity consumption of the construction site is analyzed according to the linkage model to optimize construction electricity consumption.

[0053] Specifically, the data integration unit unifies the timestamps of the field information received by the cloud platform. Data cleansing is then performed to remove invalid and duplicate data. The timestamps and units of structured data (such as temperature, voltage, and current) in the field information are standardized and converted to a text format (e.g., InfluxDB Line Protocol format). The data is then stored in a folder in the time series database, indexed by its timestamp. Unstructured data (such as images and videos) is compressed into an image format (e.g., JPEG / H.264), a unique file name is generated, and the data is uploaded to object storage, where the corresponding address is returned. Specifically, the unstructured data is first stored in object storage, where objects are constructed, including file content, metadata (file type, timestamp, or file name; this application uses the file name), and a unique identifier (file address). The unstructured data is then stored in a folder in the time series database, indexed by its timestamp, as an object. In practical applications, administrators can search and traverse the time series database based on the alarm time to trace the source of an incident. It is also possible to find all data at a specific point in time and then perform a location search to obtain relevant information about a specific location at that specific point in time.

[0054] Furthermore, a fixed, iconic point within the construction site is selected as the origin of the 3D coordinate system, such as a corner of a building or a key measurement benchmark. This 3D coordinate system is then constructed for the construction site. Based on the site's design drawings and topographic data, an accurate 3D model is constructed. This model should include 3D models of all relevant elements, including buildings, structures, construction equipment, and temporary facilities. Mobile equipment or personnel can be represented using suggested spheres, cuboids, or other shapes to depict their movement routes or location distribution. Coordinate transformation is performed on the site information, binding it to the 3D model. This information is then mapped to the 3D coordinate system to create a linked model. This linked model presents the complex construction site environment, including buildings, equipment, and more, in an intuitive manner. Compared to traditional 2D drawings or text descriptions, it provides managers and construction workers with a clearer and more comprehensive understanding of the overall site layout and detailed information. It also allows relevant personnel to view the location and status of personnel and equipment, as well as changes in environmental information, in real time, facilitating data analysis and mining, providing a scientific basis for decision-making.

[0055] Based on intrusion information from the linkage model, high-frequency violation areas are analyzed. Based on these high-frequency violation areas, high-frequency violation areas within the construction site are predicted, allowing layout adjustments to reduce violations by personnel or equipment. Furthermore, electricity usage data from the linkage model can be used to analyze power usage trends to optimize construction schedules. For example, high-power consumption processes (such as welding and lifting) can be scheduled during periods of low electricity prices to optimize resource utilization.
