[0036] In order to further understand the structure, features and other purposes of the present invention, the following detailed description is given in conjunction with the attached preferred embodiments and the accompanying drawings. The embodiments described in the drawings are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.

[0037] As a first embodiment of the present invention, Figure 1 and Figure 2 As shown, the present invention provides a construction site safety supervision system based on a drone, comprising a drone 1, a drone ground control module 2, a supervision control module 3, and a supervision mobile terminal 4. The drone 1 is deployed at the construction site and is used to fly within the construction site according to a cruising route and to collect images of the construction site. The drone ground control module 2 is deployed at the ground end of the construction site, the supervision control module 3 is deployed at the remote end, and the supervision mobile terminal 4 is configured for supervisors. At the construction site, supervisors can detachably mount the drone ground control module 2 on a mobile device 5 for use. When the drone ground control module 2 is mounted on the mobile device 5, the mobile device 5 supplies power to the drone ground control module 2. In addition, supervisors can operate the drone ground control module 2 for a long time. When the drone ground control module 2 is separated from the mobile device 5, supervisors can operate the drone ground control module 2 to control the drone 1, and can also control the movement of the mobile device 5, thereby controlling the drone 1 to land on the mobile device 5.

[0038] The drone's ground control module 2 is wirelessly connected to the drone 1. It controls the drone 1 along its navigation route, capturing images of the construction site and receiving real-time transmissions of these images. By controlling the drone's flight over the construction site, the drone obtains a 360-degree view of the construction site, helping to identify potential safety hazards and improving supervisors' efficiency.

[0039] The supervisory control module 3 is wirelessly connected to the drone ground control module 2 and drone 1, respectively. The supervisory control module 3 generates a first panoramic map of the construction site and, based on the first panoramic map, generates a cruise route that is sent to the drone ground control module 2. The supervisory control module 3 also receives images of the construction site transmitted back from drone 1 in real time to generate a second panoramic map and a new cruise route. The supervisory control module 3 generates a cruise route based on the generated panoramic map of the construction site and can determine the drone's flight path based on the actual conditions at the construction site. Each time the drone transmits an image, a new panoramic map is generated to record the progress of construction. Based on the images transmitted back of the entire construction site, the generated cruise route changes with the progress of construction, allowing for patrols in areas requiring key supervision while minimizing areas without potential safety hazards. This improves the drone's flight efficiency and resolves the issue of low supervisory efficiency caused by ineffective drone flight.

[0040] The supervisory mobile terminal 4 is wirelessly connected to the drone 1 and the supervisory control module 3. The supervisory control module 3 is responsible for establishing a construction cycle table and a construction plan table, generating supervisory tasks based on these tables and transmitting them to the supervisory mobile terminal 4. The supervisory mobile terminal 4 receives drone 1 status information and supervisory tasks from the supervisory control module 3. The supervisory control module 3 establishes a construction cycle table and a construction plan table, and transmits supervisory tasks to the supervisory mobile terminal 4, facilitating supervisory personnel to complete supervisory tasks on schedule and in a comprehensive manner.

[0041] The supervision mobile terminal 4 is electrically and signal-connected to the UAV ground control module 2, so that the supervision tasks obtained by the supervision mobile terminal 4 are automatically transmitted to the UAV ground control module 2, and the completed supervision tasks are transmitted back to the supervision control module 3 through the UAV ground control module 2 to complete the comprehensive safety supervision tasks of the construction site on time and as planned.

[0042] In this embodiment, the drone 1 is controlled by the drone ground control module 2 to acquire images of the construction site, helping to promptly identify potential safety hazards and understand the construction site's status. The images of the construction site are then transmitted back to the supervision control module 3, which generates a panoramic map of the construction site for the current supervision work and a cruising route for the next drone flight at this construction site. These panoramic maps and cruising routes, which change with the construction progress, improve the drone's flight efficiency and address the issue of inefficient supervision caused by ineffective drone flights. The supervision control module 3 establishes a construction cycle table and construction plan table for each construction project, generates supervision tasks, and sends them to the supervisory mobile terminal 4 used by supervisors. This facilitates supervisors to complete supervision tasks comprehensively and on time, avoiding safety hazards caused by inadequate supervision and resolving the issue of inadequate supervision, thereby improving construction site safety and reducing accidents.

[0043] As a second embodiment of the present invention, Figure 3 and Figure 4 Figure 2 shows the main structure of mobile device 5. It houses a first power source 51 and a second power source 52. A first magnetic contact 53, a second magnetic contact 54, and a third magnetic contact 55 are located on top of the mobile device 5. A four-wheel drive chassis 56 is located at the bottom of the mobile device 5. The drone ground control module 2 is magnetically attached to the top of the mobile device 5 via the first magnetic contact 53. The supervisory mobile terminal 4 is magnetically attached to the top of the mobile device 5 via the second magnetic contact 54. The drone 1 is magnetically attached to the top of the mobile device 5 via the third magnetic contact 55.

[0044] Figure 3 Figure 5 shows an example of a first magnetic contact 53 disposed on a lifting platform, with a lifting device connected below the lifting platform. The lifting device is disposed within the mobile device 5. In this embodiment, when the drone ground control module 2 is magnetically attracted to the mobile device 5 via the first magnetic contact 53, the drone ground control module 2 can control the lifting device to adjust the height of the drone ground control module 2, making it convenient for supervisors to use the device for extended periods of time.

[0045] Figure 3 In the view of the mobile device 5 shown in FIG, a second magnetic contact 54 is provided to the right of the first magnetic contact 53. That is, a recess for placing the supervisory mobile terminal 4 is provided on one side of the lifting platform, and the second magnetic contact 54 is provided in the recess. When the supervisory mobile terminal 4 is placed in the recess, the supervisory mobile terminal 4 can be magnetically attracted to the top of the mobile device 5 via the second magnetic contact 54.

[0046] The shape of the groove and the position of the second magnetic contact 54 are set according to the use of the supervisory mobile terminal 4. For example, if it is only necessary to place the supervisory mobile terminal 4 and magnetically attract the second magnetic contact 54, the groove can be a vertical square groove that matches the shape of the supervisory mobile terminal 4, and the second magnetic contact 54 is set at the bottom of the groove. When the supervisory mobile terminal 4 is placed in the groove, its bottom is configured to form a magnetic attraction with the second magnetic contact 54; if the supervisory mobile terminal 4 is needed, the groove can be inclined, and the second magnetic contact 54 is not set at the bottom of the groove, but on the inclined surface of the groove. When the supervisory mobile terminal 4 is placed in the groove, its back forms a magnetic attraction with the second magnetic contact 54, and the supervisory mobile terminal 4 is tilted at the top of the mobile device 5 to facilitate the supervisor to operate the supervisory mobile terminal 4.

[0047] Figure 4 The viewing direction of the mobile device 5 shown in Figure 3The left view of the mobile device 5 is equivalent to setting a third magnetic contact 55 behind the first magnetic contact 53. That is, the position of the third magnetic contact 55 is set according to the actual situation of the drone 1. The drone 1 is magnetically attracted to the top of the mobile device 5 via the third magnetic contact 55, which facilitates the landing and transportation of the drone 1.

[0048] In this embodiment, a first magnetic contact 53 and a second magnetic contact 54 are connected to the first power source 51 via a power connection, and the first magnetic contact 53 is connected to the second magnetic contact 54 via a data connection. The drone ground control module 2 and the supervisory mobile terminal 4 can be magnetically attached to the mobile device 5 for charging. When both the drone ground control module 2 and the supervisory mobile terminal 4 are magnetically attached to the mobile device 5, the drone ground control module 2 can connect to the supervisory mobile terminal 4 for data transmission.

[0049] In this embodiment, a third magnetic contact 55 is provided, connected to the second power source 52 via a power supply connection. When the drone 1 lands and is magnetically attracted to the mobile device 5, it can be charged. The charging and discharging of the first power source 51 and the second power source 52 are controlled by a control device within the mobile device 5. The control device and the wiring between its components are not shown in the diagram. The specific structures of the control device and the four-wheel drive chassis 56 are implemented using existing technology and are not described as improvements to this embodiment.

[0051] The panoramic map generation submodule 31 is electrically and signal-connected to the cruise route generation submodule 32. The panoramic map generation submodule 31 is configured to generate a panoramic map of the construction site based on images of the construction site captured by the drone 1. Each generated panoramic map is numbered to sequentially generate a first panoramic map and a second panoramic map. The panoramic map generation submodule 31 utilizes existing technology to generate a panoramic map of the construction site, facilitating viewing of the construction site's conditions. The panoramic map generation submodule 31 numbers each generated panoramic map to facilitate recording and viewing of the panoramic map.

[0052] The cruise route generation submodule 32 is used to determine the cruise points based on the panoramic map generated by the panoramic map generation submodule 31 each time, connect all the cruise points in a set order to generate a cruise route, and number each generated cruise route. The cruise route generation submodule 32 is used to combine the image information of the panoramic map to generate a corresponding cruise route according to the situation of the construction site. The cruise routes generated by the cruise route generation submodule 32 include not only cruise routes that can obtain images of the entire construction site, but also cruise routes in key supervision areas as the construction progress changes, but do not include cruise routes in non-key supervision areas without safety hazards. If necessary, cruise routes in non-key supervision areas can be included. By weakening the cruise routes in areas without safety hazards, the flight efficiency of the drone is improved, and the problem of low supervision efficiency caused by ineffective drone flight is solved. For example, if the panoramic map image information shows locations under construction and locations not under construction, the generated patrol route must include not only images of the entire construction site, but also patrol routes for the areas under construction. If the areas under construction have no long-term safety hazards, patrols in the areas under construction may not be conducted, or patrol routes may be formed based on key points in the areas under construction to ensure comprehensive safety supervision and maximize the flight efficiency of the drone. Based on the patrol route and the acquired image information, supervisors can control the drone to fly along routes other than the patrol route for areas that require further inspection, ensuring the comprehensiveness and accuracy of supervision.

[0053] The panoramic map generation submodule 31 and the cruise route generation submodule 32 are each electrically and signal-connected to the first storage submodule 33. The first storage submodule 33 is used to store each numbered panoramic map and its corresponding cruise route by number and capture time, thereby recording construction progress. By storing each numbered panoramic map generated by the panoramic map generation submodule 31 and the corresponding cruise route generated by the cruise route generation submodule 32 in the first storage submodule 33, subsequent review is facilitated. Storing each numbered panoramic map and capture time in the first storage submodule 33 accurately records every action taken by supervisors, facilitating subsequent retrieval.

[0054] First storage submodule 33 is electrically and signal-connected to first control submodule 34. First control submodule 34 is wirelessly connected to drone ground control module 2 via first wireless transmission submodule 35, enabling supervisory control module 3 to transmit the most recently numbered panoramic map and its corresponding cruise route stored in first storage submodule 33 to drone ground control module 2. The most recently numbered panoramic map and its corresponding cruise route stored in first storage submodule 33 represent the most recent information transmitted back by supervisors, providing data support for their next work, effectively improving their work efficiency and increasing the convenience of safety oversight at the construction site.

[0055] The panoramic map generation submodule 31 is electrically and signal-connected to the first control submodule 34. The first control submodule 34 is wirelessly connected to the drone 1 via the first image transmission receiving module 36. Images of the construction site transmitted from the drone 1 and received by the first image transmission receiving module 36 are then transmitted by the first control submodule 34 to the panoramic map generation submodule 31. The first image transmission receiving module 36 enables the supervisory control module 3 to receive images of the construction site captured by the drone 1.

[0056] In this embodiment, the panoramic map generation submodule 31 generates a panoramic map of the construction site with a number based on the image transmitted back by the drone 1. Then, the cruise route generation submodule 32 can determine the construction status of the construction site based on the panoramic map of the construction site, and generate the drone cruise route with the corresponding number according to the primary and secondary layout. The panoramic map and the drone cruise route with the same number are saved together in the first storage submodule 33 and sent to the drone ground control module 2, providing data support for the supervisor's next work, effectively improving the supervisor's work efficiency, and increasing the convenience of safety supervision at the construction site.

[0057] As a fourth embodiment of the present invention, Figure 6 As shown, the supervision control module 3 includes a task supervision module 37, a first storage submodule 33, a first control submodule 34, and a first wireless transmission submodule 35. The task supervision module 37 includes a construction period establishment submodule 371, a construction plan establishment submodule 372, and a supervision task generation submodule 373.

[0058] The construction cycle establishment submodule 371 and the construction plan establishment submodule 372 are respectively electrically and signally connected to the supervision task generation submodule 373. The construction cycle establishment submodule 371 is used to establish a construction cycle table based on input, determine a safety supervision schedule, and transmit the safety supervision schedule to the supervision task generation submodule 373. The construction plan establishment submodule 372 is used to establish a construction plan table based on input, determine a supervision task table, and transmit the supervision task table to the supervision task generation submodule 373.

[0059] The supervision task generation submodule 373 is electrically and signal-connected to the first storage submodule 33. The supervision task generation submodule 373 is configured to number each supervision event and the corresponding supervision task table in the safety supervision schedule. The first storage submodule 33 is configured to store each numbered supervision event and its corresponding supervision task table by number, thereby identifying the time points and tasks that supervisors need to supervise.

[0060] The first storage submodule 33 and the first control submodule 34 are electrically and signal-connected, and the first control submodule 34 is wirelessly connected to the supervision mobile terminal 4 through the first wireless transmission submodule 35, so that the supervision control module 3 sends the latest numbered supervision time and its corresponding supervision task table stored in the first storage submodule 33 to the supervision mobile terminal 4 to remind the supervisor.

[0061] This embodiment obtains a safety supervision timetable through the construction cycle establishment submodule 371, and obtains a supervision task list through the construction plan establishment submodule 372, determines the time and matters of safety supervision according to each construction project, and numbers the time of each supervision work and the corresponding supervision task list through the supervision task generation submodule 373. By saving the time of each supervision work and the corresponding supervision task list in the first storage submodule 33 according to the number, it is convenient for recording and subsequent viewing, and sending the latest numbered information to the supervision mobile terminal 4, it can remind the supervisor of the time of each supervision work and avoid the supervisor from missing safety supervision matters, thereby improving the safety of the construction site and improving the work efficiency of the supervisor.

[0062] As a fifth embodiment of the present invention, Figure 7 As shown, the supervision control module 3 also includes a construction equipment supervision module 38, which is used to establish a construction equipment database through input, save the image information, usage information and corresponding supervision task table of each construction equipment, and create a supervision list for each construction equipment.

[0063] The construction equipment supervision module 38 is electrically and signal-connected to the panoramic map generation submodule 31 and the first control submodule 34, respectively. The first control submodule 34 is wirelessly connected to the supervision mobile terminal 4 via the first wireless transmission submodule 35. The panoramic map generation submodule 31 is also used to obtain the position of each construction equipment in the panoramic map of the construction site generated each time and to intercept the image of each construction equipment. The construction equipment supervision module 38 stores the image and position of each construction equipment intercepted by the panoramic map generation submodule 31 each time into the supervision list of the corresponding construction equipment, and generates and records the storage time. Then, the construction equipment supervision module 38 sends the supervision list of each construction equipment intercepted by the panoramic map generation submodule 31 to the supervision mobile terminal 4, so that the supervisor can conduct comprehensive safety supervision of all construction equipment at the construction site through the supervision list.

[0064] In this embodiment, the construction equipment monitoring module 38 uses existing image recognition technology to compare the features of each piece of construction equipment captured by the panoramic map generation submodule 31 with the stored image information of each piece of construction equipment, thereby accurately storing the construction equipment information. The panoramic map generation submodule 31 obtains information about the actual construction equipment present at the construction site during each supervision operation. The construction equipment monitoring module 38 then sends a pre-stored supervision list of the corresponding construction equipment to the supervisory mobile terminal 4, providing supervisors with a corresponding supervision task list for each piece of construction equipment at the construction site, ensuring comprehensive safety supervision of all construction equipment at the construction site.

[0065] As a sixth embodiment of the present invention, Figure 8 As shown, the supervision control module 3 includes a construction worker supervision module 39, which is used to establish a construction worker database through input and save the face and identity information of each construction worker.

[0066] The construction worker monitoring module 39 is electrically and signal-connected to the panoramic map generation submodule 31 and the first control submodule 34, respectively. The first control submodule 34 is wirelessly connected to the monitoring mobile terminal 4 via the first wireless transmission submodule 35. The panoramic map generation submodule 31 is also used to obtain the locations of all construction workers in each generated panoramic map and to extract an image of each construction worker. This allows the construction worker monitoring module 39 to match the construction worker's face and identity information with the image of each construction worker obtained by the panoramic map generation submodule 31, and to transmit the matched construction worker's face and identity information, as well as their location, to the monitoring mobile terminal 4, thereby facilitating comprehensive safety supervision of all construction workers at the construction site by supervisors.

[0067] This embodiment obtains the information of the actual construction workers at each supervision work site through the panoramic map generation submodule 31, and the construction worker supervision module 39 sends the pre-saved information of the corresponding construction workers to the supervision mobile terminal 4, providing the supervisor with the information of each construction worker at the construction site, ensuring that the supervisor conducts comprehensive safety supervision of all construction workers at the construction site.

The second control submodule 21 is used to transmit the cruise route received by the second wireless transmission submodule 24 to the second wireless communication submodule 22. The second wireless communication submodule 22 is used to wirelessly transmit the cruise route to the drone 1, enabling the drone 1 to fly according to the cruise route.

[0070] The flight control submodule 23 is electrically and signal-connected to the second wireless communication submodule 22. The flight control submodule 23 is used to control the drone 1 to hover at any cruising point along the cruising route, and to control the drone 1 to fly along the controlled route, thereby enabling the drone ground control module 2 to control the drone 1.

[0071] The second control submodule 21 is wirelessly connected to the drone 1 via the second image transmission and receiving module 25. The second control submodule 21 is also electrically and signal-connected to the display submodule 26. The second image transmission and receiving module 25 is configured to receive images of the construction site captured by the drone 1. The second control submodule 21 is also configured to transmit the images of the construction site captured by the drone 1 to the display submodule 26. The second control submodule 21 is also configured to transmit the panoramic map received by the second wireless transmission submodule 24 from the supervisory control module 3 to the display submodule 26, enabling supervisors to view images of the construction site in real time.

[0072] The second control submodule 21 is electrically and signal-connected to the supervisory mobile terminal 4 through the interface module 28 , so that the supervisory mobile terminal 4 is wiredly connected to the UAV ground control module 2 and the supervisory task is automatically transmitted.

[0073] In this embodiment, the second control submodule 21 is used to control the flight of the drone 1 and collect images of the construction site. The collected images of the construction site will be displayed in real time and transmitted back to the supervision and control module 3 for storage. Supervisors can view the images of the construction site in real time at the construction site and understand the safety status of the construction site. The supervision and control module 3 can also conduct a comprehensive analysis of the safety hazards at the construction site through the transmitted images, and assist on-site supervisors in conducting comprehensive safety supervision work.

[0074] As an eighth embodiment of the present invention, Figure 10 As shown, the drone 1 includes a third control submodule 11 , a first wireless communication submodule 12 , a flight control module 13 , a navigation module 14 , an aerial photography module 15 and an image transmission module 16 .

[0075] The third control submodule 11 is wirelessly connected to the UAV ground control module 2 via the first wireless communication submodule 12. The third control submodule 11 is electrically and signal-connected to the navigation module 14, which in turn is electrically and signal-connected to the flight control module 13. The first wireless communication submodule 12 is used to receive the cruise route and flight control signals from the UAV ground control module 2. The navigation module 14 is used to control the flight control module 13 to fly according to the cruise route and flight control signals.

[0076] The third control submodule 11 is electrically and signal-connected to the aerial photography module 15 and the image transmission module 16. The aerial photography module 15 is electrically and signal-connected to the image transmission module 16, which is wirelessly connected to the UAV ground control module 2 and the supervisory control module 3. The aerial photography module 15 is used to capture images of the construction site under the control of the third control submodule 11. The image transmission module 16 is used to transmit the captured images of the construction site to the UAV ground control module 2 and the supervisory control module 3 in real time.

[0077] As a ninth embodiment of the present invention, Figure 11 As shown, the drone 1 also includes a power monitoring module 17, which is electrically and signal-connected to the third control submodule 11. The third control submodule 11 is wirelessly connected to the drone ground control module 2 and the supervisory mobile terminal 4 through the first wireless communication submodule 12.

[0078] The power monitoring module 17 is used to obtain the power information of the drone 1, and the first wireless communication sub-module 12 is used to transmit the power information of the drone 1 to the drone ground control module 2 and the supervision mobile terminal 4, so that the drone ground control module 2 can display the power information of the drone 1 in real time when the drone 1 is working, and the supervisor can obtain the power information of the drone 1 through the supervision mobile terminal 4.

[0079] In this embodiment, the power monitoring module 17 obtains the drone's power information and transmits it to the drone ground control module 2. When the supervisor is performing supervision work, the drone's power information will be displayed in real time, making it convenient for the supervisor to understand the drone's real-time power level. When the drone is not operating, the power monitoring module 17 will transmit the drone's power information to the supervisory mobile terminal 4. The supervisor using the supervisory mobile terminal 4 can obtain the drone's power information before performing supervision work, ensuring that the drone can be used normally during each supervision work.

[0080] As a tenth embodiment of the present invention, Figure 11As shown, the drone 1 also includes an auxiliary sensor module 18, which is electrically and signal-connected to the third control submodule 11. The third control submodule 11 is wirelessly connected to the drone ground control module 2 and the supervisory control module 3 through the first wireless communication submodule 12.

[0081] The auxiliary sensor module 18 is used to obtain environmental data of the construction site, and the first wireless communication sub-module 12 is used to transmit the environmental data of the construction site to the UAV ground control module 2 and the supervision control module 3, so that the UAV ground control module 2 can display the environmental data monitored by the auxiliary sensor in real time when the UAV 1 is working, and the supervision control module 3 can obtain the environmental data monitored by the auxiliary sensor for potential risk analysis.

[0082] In this embodiment, auxiliary sensors equipped on drone 1 monitor environmental data at the construction site, displaying it in real time on drone ground control module 2 and transmitting it back to supervisory control module 3 for potential risk analysis and storage. This allows supervisors to understand the safety status of the construction site, and supervisory control module 3 assists on-site supervisors in comprehensive safety oversight. Auxiliary sensors include, but are not limited to, thermal imaging cameras for detecting safety hazards at the construction site that are difficult to detect with the naked eye, air quality sensors for monitoring air quality at the construction site, and noise sensors for monitoring noise pollution levels at the construction site.

[0083] When this system is in use, during the deployment phase, the remote supervision and control module 3 first imports the project plan through the construction cycle establishment submodule 371 to generate a construction cycle table, and the construction plan establishment submodule 372 enters the construction plan table; the construction equipment supervision module 38 builds the equipment database, and the construction personnel supervision module 39 enters the personnel's facial and identity information.

[0084] During the panoramic map construction phase, supervisors at the construction site use the drone's ground control module 2 to activate the drone 1 via the flight control submodule 23. The navigation module 14 controls the drone to scan the entire site along a pre-set path. The aerial photography module 15 captures images of the construction site from multiple angles, and the image transmission module 16 transmits these images back to the supervisory control module 3 in real time, completing the collection of the initial patrol data. The panoramic map generation submodule 31 then performs a three-dimensional reconstruction of the images, generating a numbered first panoramic map. The patrol route generation submodule 32 generates an initial patrol route based on the map's feature points and stores it in the first storage submodule 33, completing the map generation and storage.

[0085] During the drone patrol phase of safety monitoring at the construction site, the monitoring control module 3 transmits the patrol route to the drone ground control module 2 via the first wireless transmission submodule 35. Its second control submodule 21 analyzes the route data and directs the drone 1 to fly along the planned path via the flight control submodule 23. During the patrol, the drone 1 collects environmental data (such as temperature, humidity, and dust concentration) through the auxiliary sensor module 18 and transmits it back synchronously with the aerial imagery. The display submodule 26 of the ground control module 2 displays the drone's perspective and sensor data in real time. The first image transmission receiving module 36 receives the newly captured image, and the panoramic map generation submodule 31 generates a second panoramic map by comparing it with the first panoramic map. The construction equipment monitoring module 38 automatically identifies changes in equipment position in the map and updates the equipment monitoring list. The patrol route generation submodule 32 adjusts the patrol points based on the new map to avoid newly added obstacle areas. The updated route is pushed to the site via the first wireless transmission submodule 35. At the same time, the supervision task generation submodule 373 combines the construction cycle table with the real-time progress to generate a supervision task table containing time, area, and inspection items. The task data is synchronized to the supervision mobile terminal 4 through the interface module 28. The supervisor views the task details through the mobile terminal 4 and switches the drone to manual mode through the flight control submodule 23 when necessary. The drone 1 performs fixed-point hovering and shooting of high-risk areas according to the task requirements, and the power monitoring module 17 provides real-time feedback on the remaining battery life. When the power monitoring module 17 detects that the drone's power is less than 20%, it triggers an automatic return command. The mobile device 5 moves to the nearest charging point via the four-wheel drive chassis 56, and the drone is adsorbed and charged through the third magnetic contact 55.

[0086] This system dynamically matches construction cycle tables with real-time maps, enabling comprehensive monitoring of the entire project process from planning to completion. This system provides comprehensive, intelligent oversight of construction site equipment, personnel, and the environment, significantly improving safety management efficiency. The coordinated operation of these modules forms a complete closed-loop system of "data collection - analysis and decision-making - task execution - feedback and optimization," meeting the dynamic monitoring needs of complex construction scenarios.
