Safety helmet, wearing state detection method and device, and computer-readable storage medium

Abstract

The invention discloses a safety helmet, a wearing state detection method and device, and a computer-readable storage medium, belonging to the field of construction site equipment. The safety helmet includes: a cap body, a first capacitive proximity sensor and a processor disposed on the cap body; the first capacitive proximity sensor is electrically connected to the processor; the processor is configured to collect the first capacitive proximity sensor the first capacitive signal; calculate the first capacitive variable corresponding to the first capacitive signal collected at present and the first capacitive signal collected last time; obtain the last wearing state of the helmet and the preset threshold value of the first capacitive value; according to the first A capacitance variable, the last wearing state of the helmet, and a preset threshold value of the first capacitance determine the current wearing state of the helmet. The safety helmet can reduce the misjudgment frequency of the wearing state of the safety helmet caused by holding the safety helmet, touching the connection line between the capacitive proximity sensor and other components, entering the conductor superposition environment, etc., and improving the detection accuracy.

Description

technical field [0001] The invention relates to the field of construction site equipment, in particular to a safety helmet, a wearing state detection method and device, and a computer-readable storage medium. Background technique [0002] At the construction site, the correct wearing of safety helmets is very important for the construction workers' safe construction. However, for some construction workers with weak safety awareness, they often do not wear safety helmets. Therefore, it is very necessary to monitor the wearing status of construction personnel's safety helmets. Wherein, the wearing state of the safety helmet includes: a state of wearing the helmet and a state of taking off the helmet. [0003] In related technologies, 2 to 3 capacitive proximity sensors, capacitive sensing controllers, and processors of the same specification are arranged on the cap body of the helmet to detect the wearing state of the helmet. The capacitive sensing controller collects and pro...

Problems solved by technology

[0005] In the superimposed environment of conductors such as holding a safety helmet and touching the connecting wires between the capacitive proximity sensor and other components, the capacitive signal of the capacitive proximity sensor will also change, and the changed capacitive signal is collected by the capacitive sensing controller, and Make the processor process the changing capacitive signal, resulting in misjudgment of the wearing state of the helmet and poor detection accuracy
