基于GNSS+蓝牙的智能安全帽系统

With the acceleration of the digital transformation of China\'s construction industry, the construction of intelligent construction sites has become an inevitable trend in the industry. In this process, intelligent helmet, as an important data acquisition equipment, has been widely studied and applied. At present, intelligent helmets on the market are often limited to a single scene in terms of positioning functions, and mainly outdoor positioning, which is difficult to meet the indoor and outdoor positioning needs of complex construction site environments; at the same time, most intelligent construction site management systems are multi-functional and comprehensive, ignoring the depth optimization of specific functions and the actual needs of specific construction sites. In view of the above problems, this paper proposes an innovative multi-scene personnel fusion positioning scheme for intelligent construction sites, which combines Bluetooth and GNSS positioning technology to achieve indoor and outdoor fusion positioning, and designs an effective positioning switching scheme to solve the ping pong effect, overcoming the limitations of other existing intelligent helmets in positioning scenes. In addition, the intelligent helmet system has functions such as real-time positioning, historical track playback, information management and aerial upgrade. All functions of the system can operate stably and basically meet the requirements of intelligent site management.
