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 comprises a helmet body, a first capacitive proximity sensor and a processor, wherein the first capacitive proximity sensor and the processor are arranged on the helmet body; the first capacitive proximity sensor is electrically connected with the processor; and the processor is configured to acquire a first capacitance signal of the first capacitive proximity sensor, calculate a first capacitance variable corresponding to the currently acquired first capacitance signal and the first capacitance signal acquired last time, obtain the last wearing state of the safety helmet and a first capacitance preset threshold value, and determine the current wearing state of the safety helmet according to the first capacitance variable, the last wearing state of the safety helmet and the first capacitance preset threshold. According to the invention, the misjudgment frequency of the wearing state of the safety helmet caused by the fact that a user holds the safety helmet by hand, touches connecting wires between the capacitive proximity sensor and other components, enters a conductor superposition environment and the like can be reduced, and the detection precision is improved.

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
