SAFETY HELMET AND INTELLIGENT MODULE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/081873
Kind Code:
A1
Abstract:
An intelligent module (100) for a safety helmet (200). The intelligent module comprises a control unit (10), an inertial measurement unit (30), and a power source (40) supporting the operation of the intelligent module (100), wherein the inertial measurement unit (30) is configured to measure motion parameters of the safety helmet (200); the control unit (10) pre-sets a motion parameter range of a helmet wearing event; and the intelligent module (100) determines whether the motion parameters measured by the inertial measurement unit (30) satisfy the motion parameter range of the helmet wearing event pre-set by the control unit (10), so as to confirm a helmet wearing action of the safety helmet (200). By means of the inertial measurement unit (30) recognizing and determining a specific helmet wearing action, the precision and accuracy of determination are improved, and the low power consumption characteristic thereof also extends the battery life of a self-contained battery.
