Abstract

The invention belongs to the technical field of safety helmet quality detection and provides a safety helmet quality detection and construction safety evaluation system. The system comprises a safety helmet quality detection device, a multi-channel analog switch, a signal conditioner, an A/D converter, a lower computer and an upper computer, wherein the safety helmet quality detection device is connected with the multi-channel analog switch, the multi-channel analog switch is connected with the signal conditioner, the signal conditioner is connected with the A/D converter, the A/D converter is connected with the lower computer, and the lower computer is connected with the upper computer, so problems that stress data acquired during safety helmet quality detection is single and incomplete, and stress conditions of the head in all directions of a person wearing a safety helmet in real life cannot be comprehensively simulated and evaluated when the person is hit, and a specific detection device is in a lacking state are solved. The system is advantaged in that data collection is comprehensive, safety helmet quality detection is more rigorous, and safety helmet quality qualification evaluation is more accurate.

Description

technical field [0001] The invention relates to the technical field of helmet quality detection, in particular to a safety helmet quality detection and construction safety evaluation system. Background technique [0002] Safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. It has multiple important protective functions such as cushioning, shock absorption, and stress dispersion. Therefore, the quality of helmets needs to be strictly supervised. Most of the existing quality inspection methods for helmets are to use hard objects to knock or drop heavy objects to simulate the process of helmets being hit and collect the maximum impact. The force value is used to detect the quality of the helmet. This method can only analyze the situation of the vertical downward impact force on the head of the person, but cannot analyze the torsional force and lateral force received by the human head, and cannot fully sim...
