million units nationwide by the end of 2025). Ensuring safe elevator operation and emergency response has become one of the core demands for public welfare. According to national standards such as the "Remote alarm system for lifts" (GB/T 24475-2023), elevators must be equipped with a five-party communication system as standard, and this system must include remote alarm functionality to ensure that passengers can directly contact rescue personnel in emergency situations such as entrapment.
Traditional solutions involve adding a SIM card-based telephone module to the analog five-party communication device to enable calls with rescue organizations. However, these traditional approaches face critical bottlenecks:
They rely on personal, real-name SIM cards, which cannot meet the batch deployment needs of elevator companies. This effectively prevents elevator companies or service organizations from continuing to provide remote alarm services to elevator users.

Scenarios involving new elevator installations or modernizations of existing ones often face difficulties with on-site cabling. Wired communication solutions suffer from high deployment costs and poor flexibility.
In this context, Shanghai TransEngines Technologies Co., Ltd. independently developed the "Elevator GlobalConnect Remote Alarm and Communication System." Based on digital communication + IoT SIM card + VoIP technology, this system overcomes the limitations of SIM card voice controls and the difficulties of on-site cabling, representing a technological direction for elevator emergency rescue communication system solutions.

The "Elevator GlobalConnect Remote Alarm and Communication System," independently developed by Shanghai TransEngines Technologies Co., Ltd, employs a proprietary digital communication device. It supports local wired intercom and enables wireless intercom and remote alarm calling functions through its proprietary VoIP alarm management platform. This VoIP platform also supports the statistics and traceability of alarm call records. The digital communication device features strong anti-interference capability, providing stable and clear voice quality even in the harsh, noisy operating environment of an elevator. By building a voice communication link using IoT card-based VoIP technology, the system eliminates the constraints of physical cables, fundamentally solving technical bottlenecks such as on-site wiring aging, signal interference, and limited communication range, ensuring clear, low-latency voice calls. The system is designed and developed in full compliance with the latest policies and standards, facilitating easy integration of digital functionalities.
