NB-IoT (Narrow Band Internet of Things)-based intelligent helmet for accurately positioning ultrahigh river-crossing iron tower construction workers and application

Abstract

A worker accurate height positioning intelligent helmet for ultrahigh river-crossing iron tower construction based on NB-IoT relates to the technical field of wireless communication positioning, and is characterized by comprising a visor, a helmet shell, a head band, a head support, a sweatband, a head band and an NB-IoT chip; the cap peak and the cap shell are integrally connected, the head band is installed in the cap shell, the head band is supported by the head support, the head band is arranged at the tail end of the head support, and the sweatband is installed at the position where the head band is located on the inner side of the position of the cap peak; the NB-IoT chip is arranged in the head band; the intelligent safety helmet is in communication connection with a background cloud service platform through the NB-IoT chip. According to the worker accurate height positioning intelligent helmet based on ultrahigh river-crossing iron tower construction, a new generation of communication technology NB-IoT communication technology is adopted, real-time positioning of a wearer and help information sending can be achieved, and monitoring and management of project field personnel are achieved.

Description

technical field [0001] The invention relates to the field of electric power substation engineering construction, in particular to a smart helmet for precise height positioning of workers based on the construction of an ultra-high cross-river iron tower. Background technique [0002] Infrastructure work is related to the development of the country's society and economy, and safe production and quality assurance are important goals of infrastructure operations. The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Exchange and communication, that is, things are closely related. The Internet of Things is widely used in the integration of networks through communication perception technologies ...

Problems solved by technology

In addition, in terms of supporting big data, the data collected by NB-IoT connections can be directly uploaded to the cloud, while technologies such as Bluetooth and Wi-Fi do not have such convenience

[0009] Due to the high height of the spanning tower, complex structure, many nodes, and many working conditions, finite element analysis and calculation of multi-scale models are required. The overall engineering volume is large, and the professional span is high, and the construction period is long; The wide construction scope, complex personnel structure and objective existence of particularity, dispersion and mobility make the safety management of the project construction less controllable. Compared with general construction projects, the cross-river super high-speed iron tower project has higher risks sex
