AI Technical Summary

Technical Problem

The existing high-altitude working seat belt system has a single contact switch detection mechanism that lacks redundant design, resulting in high risk of virtual hooking or decoupling of hooks. Especially in complex tower structures, misjudgment occurs frequently and cannot adapt to dynamic scenarios of alternating double hooks.

Method used

The triple collaborative monitoring mechanism is adopted to verify the wearable status of the seat belt body through the metal conductive sheet in the hanging ring. The double hook integrates metal conduction and mechanical pressing dual switches, and combines the main control box to make multi-source signal fusion decisions to achieve graded alarms.

Benefits of technology

Accurately identify the effective mounting status of the hook, reduce the false alarm rate to nearly zero, improve accident response efficiency, and build a full-link protection system.

Abstract

The invention relates to the technical field of safety ropes, and particularly discloses a safety belt, a safety belt lock catch alarm device and an alarm method.The safety belt lock catch alarm device comprises a lock catch alarm device body, a safety belt body, a hanging ring, a tower climbing rope and a hook. The safety belt wearing state is verified through a metal conducting strip in a hanging ring, and the foundation anchor point is reliable; the double hooks integrate metal conduction and mechanical pressing double switches, effective mounting of a metal or nonmetal area of the iron tower is accurately recognized, and the misjudgment defect of a traditional single detection mode is eliminated; the main control box is fused with multi-source signals to establish a grading decision, and when it is detected that a hanging ring is not fixed, double hooks are not mounted or single hook communication fails, sound-light alarm and internet-of-things remote early warning are triggered. According to the alarm method, the false alarm rate can be compressed to be nearly zero, the accident response efficiency is remarkably improved, and a fixed end-dynamic end-equipment end full-link protection system is constructed.
