Abstract:

This paper systematically analyzes the core requirements of the elevator trapped person alarm system and the major challenges faced by signal transmission, and elaborates in detail on the architecture and signal transmission principle of the elevator trapped person alarm system based on LoRa. It focuses on studying the key factors affecting the transmission reliability of LoRa signals in the special environment of elevators , and puts forward targeted reliability assurance strategies. Combined with practical application scenarios and inspection experience, the key points of the system in installation, debugging, and daily inspection and maintenance are discussed. The research shows that a rationally designed and deployed LoRa-based elevator trapped person alarm system can significantly improve the reliability of signal transmission, provide a more timely and effective alarm and rescue channel for trapped passengers, and has important engineering application value and promotion prospects.
