[0026] As Figure 1 and Figure 2 shown, the ground wind speed sensor A1 is arranged on the mounting rod at the tail of the crane vehicle body for detecting the wind speed of the ground environment in real time. The inclination sensor A2 is arranged in the vertical direction at the center of gravity of the crane vehicle body for detecting the inclination attitude of the vehicle body in real time.

[0028] The safety monitoring system for the overall hoisting construction process of a wind turbine provided in this specification detects the wind speed of the ground and altitude environments through the ground wind speed sensor and the altitude wind speed sensor respectively, detects the inclination attitude of the vehicle body through the inclination sensor, and detects the magnitude of the force borne by the rod member of the crane arm through the crane arm stress sensor, and sends the detection data of each sensor to the human-machine interaction interface, enabling the user to timely understand the hoisting process according to the acquisition values of each sensor and assisting the operator to improve the safety of the overall hoisting construction of the wind turbine.

[0029] In some embodiments, the on-site detection end further includes a swing detection sensor A5. The swing detection sensor A5 is arranged at the end of the crane arm for measuring the swing magnitude of the wind turbine during the hoisting process.

[0030] Specifically, as Figure 2 shown, the swing detection sensor A5 may include an image displacement sensor host A51 and an image displacement sensor scale target A52.

[0031] The image displacement sensor host A51 is installed at the end of the crane boom; the image displacement sensor host emits a detection beam vertically downward.

[0032] The image displacement sensor scale target A52 is installed on the hub of the wind turbine and is within the detection range of the image displacement sensor host. An adsorption type image displacement sensor scale target is arranged on the upper side of the hoisted wind turbine hub and leveled, facing directly towards the image displacement sensor host.

[0033] In some embodiments, such as Figure 2 and Figure 3 shown, the on-site detection end further includes a video camera A6. The video camera A6 is arranged at the end of the crane boom and is used to obtain images of the connection area between the wind turbine hub and the hoisting rope in real time.

[0034] In some embodiments, the safety monitoring system further includes a drone carrying a camera and a first wireless communication module.

[0035] The drone is used to fly in the construction area during the hoisting process and obtain real-time images during the construction process.

[0045] Then, the auxiliary safety monitoring device starts to work, measures data such as the ground wind speed, the high-altitude wind speed, the vehicle body tilt angle, and the crane arm stress in real time, and displays them on the human-machine interaction interface in the cockpit. The image displacement sensor host measures in real time the scale target horizontally installed on the wind turbine hub, and measures in real time the swing amplitude magnitude of the wind turbine in the 360° direction relative to the image displacement sensor host fixedly installed horizontally at the top of the crane arm, and graphically displays it in real time on the human-machine interaction interface in the cockpit. The video camera arranged in the top area of the crane arm monitors the contact area between the lifting rope and the flywheel hub in real time, and displays it in real time on the human-machine interaction interface in the cockpit. The measured data information in real time is compared and judged with the set warning and alarm thresholds. When the warning and alarm thresholds are reached, the cockpit operator and the relevant on-site staff are prompted by sound and light, and corresponding measures are taken.
