Safety helmet timer scheduling method and system based on abnormal helmet removal record

Abstract

The invention belongs to the technical field of Internet of Things and communication, and particularly relates to a safety helmet timer scheduling method and system based on an abnormal helmet removal record, and the method comprises the steps: setting an abnormal helmet removal safety frequency Ms and an abnormal helmet removal danger frequency Md, determining a first timing period adjustment factor according to the abnormal cap-off frequency N, the abnormal cap-off safety frequency Ms and the abnormal cap-off danger frequency Md recorded by the cloud platform, and obtaining the safety helmet reputation; obtaining the use condition of the safety helmet terminal in the current period and a safety helmet reputation factor to obtain a second timing period adjustment factor; adjusting the timing period according to the first timing period adjustment factor and the second timing period adjustment factor; the next period is carried out according to the adjusted timing period; according to the invention, the accuracy of abnormal cap-off identification is improved, the power consumption of the terminal is reduced, the working period of the timer of the terminal is adjusted by using the historical abnormal cap-off information, and the probability of safety accidents caused by non-standard wearing of safety helmets or overlong use period of the safety helmets is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the field of Internet of Things and communication technologies, and in particular relates to a method and system for scheduling a helmet timer based on an abnormal hat-off record. Background technique [0002] The safety helmet is a shallow dome hat made of steel or similar materials to protect the top of the head, which is widely used in construction and electrical engineering. With the rapid development of IoT perception detection, network transmission, and intelligent processing technologies, the functions of safety helmets have been improved, and they have gradually become intelligent, resulting in intelligent safety helmets and hat-off monitoring devices. [0003] The invention patent CN2017109315984 uses a laser ranging sensor to measure the distance between the helmet and the head of the wearing user, and transmits the data measured by the laser sensor to the central controller, and the central controller determines whet...

AI Technical Summary

Problems solved by technology

The invention can realize the detection of the wearing state of the helmet, but it does not detect various wearing states of the helmet, and the monitoring accuracy is not high. In addition, the invention does not set a timer to dynamically monitor the helmet, and cannot target various wearing of the helmet The status dynamically adjusts the monitoring cycle of the helmet, which does not meet the needs of intelligence

In the existing technology, methods such as video monitoring and image recognition are also used to monitor the wearing of helmets by users, but the technology used is complicated, the number of equipment is large, and the data obtained is large, and the accuracy of judging whether the helmet is worn correctly is not high.
