High-definition cameras continuously collect video footage, capturing real-time data on personnel activity trajectories, traffic flow changes, and abnormal behaviors. Smoke sensors monitor the concentration of smoke particles in the environment, outputting a fire warning signal when the concentration reaches a preset threshold. Temperature and humidity sensors collect ambient temperature and humidity data. Gas concentration sensors detect and alert for various toxic and harmful gases in real time. Vibration sensors trigger an alarm mechanism when they detect abnormal vibrations caused by violent damage or illegal climbing. Liquid level sensors monitor the water level of the city's drainage system, providing data support for urban flood control and drainage. These sensors are also used in urban intelligent access control systems, fire alarm systems, elevator operation monitoring systems, and traffic signal control. IoT devices such as systems connect their own operational status data to the perception layer to achieve comprehensive perception of the operational status of various urban facilities. Drones, as mobile sensor carriers, are equipped with different types of sensors. After receiving mission instructions from the take-off and landing platform, they take off automatically and travel to the designated monitoring area according to the preset flight route. Upon reaching the target area, the high-definition camera on the drone dynamically collects video of the monitoring area, the gas sensor detects the concentration of harmful gases in the atmosphere in real time, the thermal imager detects the surface temperature distribution of objects to find potential heat source anomalies, and the noise sensor monitors the environmental noise. The data collected by each sensor is stored in the drone's local storage device in real time. When the flight mission ends or the data transmission conditions are met, the data is sent back to the platform layer.

[0053] Step 2: When an emergency occurs or a new safety hazard area is discovered, staff quickly deploy emergency sensors based on the actual situation on site. Staff place the required type of sensor inside the two fourth electric telescopic masts 59 on the left and right sides, and control the transport drone 51 to activate the fourth electric telescopic masts 59 on both sides. The fourth electric telescopic masts 59 on both sides drive the second clamping frames 510 at the corresponding positions to move inward, so that the second clamping frames 510 on both sides clamp and fix the sensor externally. The transport drone 51 moves to the outside of the mounting column 1 at the designated position according to the predetermined route, and hovers above the circular groove shell 31 at the designated position according to the predetermined program. The pre-set program inside the transport drone 51 controls the third electric telescopic mast 58 and the fifth electric telescopic mast 513. The fourth motor 515 and the two third electric telescopic rods 58 on the left and right extend to drive the rotating frame 56 to rotate downward to a vertical position in the inner cavity of the straight groove shell 55. The fifth electric telescopic rods 513 on the left and right extend to drive one end of the support frame 512 at the corresponding position to move inward. Then, with the cooperation of the support frames 512 on the left and right, the mounting shaft 511 is driven to rotate, so that the mounting shaft 511 on the left and right drives the mounting arm 514 at the corresponding position to drive the rotating roller 516 to move inward and contact the left and right sides of the sensor. The fourth electric telescopic rods 59 on the left and right shorten to drive the second clamping frame 510 at the corresponding position to move outward to release the fixation of the sensor. The fourth motors 515 on the left and right drive the rotating roller 516 at the corresponding position to rotate, so that the sensor moves downward to the inner cavity of the slot plate 312 under the drive of the rotating roller 516.

[0054] Step 3: The pre-programmed control system inside the mounting column 1 starts the first electric telescopic rod 313, the third motor 49, the electronic clutch 47, the second motor 44, the drive motor group 34, and the first motor 38. The upper and lower sets of the first electric telescopic rods 313 drive the first clamping frame 314 at the corresponding positions to move inward. The first clamping frames 314 on both the front and rear sides clamp and fix the sensor inside the slot plate 312. The third motor 49 drives the second worm gear 410 to rotate clockwise or counterclockwise. The second worm wheel 48 rotates synchronously under the action of the rotational force of the second worm gear 410. The rotation of the left and right electrically controlled clutches 47 controls the transmission connection between the second worm gear 48 and the left and right rotating seats 46, so that, with the cooperation of the rotating seats 46, the corresponding circular groove shell 31 is driven to rotate clockwise or counterclockwise to a specified direction. The second motor 44 drives the first worm 45 to rotate clockwise or counterclockwise, and the first worm gear 43 rotates synchronously under the rotational force of the first worm 45, driving the base shell 41 to rotate clockwise or counterclockwise to a specified position, thereby adjusting the directional position of the two circular groove shells 31. The drive motor 34 inside the circular groove shell 31 drives the rollers inside the roller seat 33 to rotate, causing the roller seat 33 to move clockwise or counterclockwise along the outer circumference of the annular track 32. This, in conjunction with the upper mounting plate 35, the limiting guide rail 36, the limiting slider 37, and the connecting seat 311, drives the sensor inside the slotted plate 312 to rotate axially, thereby adjusting the axial angle of the sensor inside the slotted plate 312. The four first motors 38 on each side drive the lead screw in the lead screw assembly 39 at the corresponding position to rotate, causing the lead screw nut in the lead screw assembly 39 to rotate... Under the action of rotational force, the upper limit slider 37 at the corresponding position is driven to move up or down. The upper limit slider 37 drives one end of the connecting frame 310 to move up or down, so that with the cooperation of the connecting seat 311, the sensor inside the slotted plate 312 is driven to tilt to the specified direction position, thereby adjusting the angle of the sensor inside the slotted plate 312 to align with the specified working position. The sensor inside the slotted plate 312 starts working, collects various key data on site, and transmits the data to the platform layer in real time through the network layer, providing timely and accurate data support for emergency command and rescue decision-making.

[0055] Step 4: After receiving the data transmitted from the perception layer, the platform layer uses big data processing technology to preprocess the data, improving data quality. It also employs distributed storage technology to disperse massive amounts of data across multiple storage nodes, ensuring data security and scalability, and facilitating subsequent data querying and analysis. Based on artificial intelligence and machine learning algorithms, the platform layer constructs various urban safety analysis models. The video analysis model processes the collected video data, using image recognition, behavior analysis, and other technologies to identify abnormal behaviors. The prediction model combines historical data and real-time monitoring data, using time series analysis and machine learning prediction algorithms to predict safety events such as fires, floods, and equipment failures. When monitoring data exceeds a preset threshold or the analysis model detects an anomaly, the system automatically triggers an early warning program. Depending on the severity and type of the warning, the platform layer adopts automated and manual responses to ensure that safety events are handled in a timely manner. The platform layer also uses data visualization technology to visualize the processed and analyzed urban safety-related data.

[0056] Step 5: The application layer provides public safety departments with real-time monitoring images and personnel behavior analysis results. Relevant departments can access real-time video from high-definition cameras through the system platform to monitor key areas and take timely preventive measures to maintain urban public safety and order. When a fire signal is detected, the application layer notifies the fire department and provides them with detailed information such as the specific location of the fire, surrounding road conditions, and building structure to help firefighters develop a scientific and reasonable rescue plan. The system links fire-fighting facilities, automatically activates the automatic sprinkler system, and closes fireproof roller shutters to respond to and extinguish the initial fire, minimizing fire losses as much as possible. The application layer monitors traffic flow in real time and analyzes video data collected by traffic cameras to obtain information such as the number of vehicles and their speed on each road segment. Based on changes in traffic flow, the system analyzes the causes of traffic congestion, automatically adjusts traffic light durations, optimizes traffic efficiency, and quickly locates the accident site when a traffic accident is detected, notifying traffic police and rescue agencies for timely handling. The application layer monitors urban infrastructure in real time, analyzes equipment operation data transmitted from the perception layer, combines historical equipment operation data with industry standards, predicts the likelihood of equipment failure, and notifies relevant departments and personnel to arrange maintenance and repair plans in advance.
