The construction site intelligent safety protection air conditioning clothing that belongs to the category of human safety protection. By embedding the airbag, electronic control components, gas cylinders and conduction devices into the construction safety vest, Three protective suits, SHW12, SHW13 and SHW22, are designed and tested on the trigger sensitivity, thickness, weight, breaking strength, elongation at break, tearing strength and burning rate of the bag. At the same time, the refrigeration system is cleverly integrated into the protective suit, and the algorithm module parameters in the control unit are found out for optimization in the wearing test on the construction site, and the waveform of acceleration and angular velocity collected by the six axis is superimposed and synthesized for filter processing. Through a series of experiments, it is proved that the protective clothing has a good buffer and energy dissipation effect, and has a good protection effect on the workers when accidents happen.
