More specifically, temperature and humidity sensors are installed in the corners around the working platform 5, and gas detection sensors are installed in locations with good air circulation to ensure timely detection of changes in environmental parameters.

[0053] Specifically, in this embodiment, the human body status monitoring module 305 is installed on the worker's body via a wearable device (such as a sensor built into a safety helmet or a belt-type monitoring device). This module can be wirelessly connected to the monitoring system of the insulated bucket truck to collect and transmit the worker's physiological data (such as heart rate and body temperature) and their position and posture on the work platform 5.

[0057] During operation, the automatic monitoring system 3 monitors the environmental parameters of the work area, the operating status of the insulated bucket truck, and the physical condition of the workers in real time. When the automatic monitoring system 3 detects an abnormality, the control module 4 controls the automatic opening and closing mechanism 2 of the insulating cover to open quickly, causing the insulating cover 1 to unfold rapidly and cover the upper part and surrounding area of ​​the working platform 5 of the insulated bucket truck, forming a closed protective space.
