AI Technical Summary
Existing gas alarms are all-in-one structures, with sensors, communication units, and power supplies fixed inside. They cannot be flexibly added or removed. If the sensor fails, the entire unit must be disassembled, resulting in long maintenance downtime and making them difficult to adapt to complex industrial environments.
It adopts a modular design, and the shell and functional modules are hot-swappable through a foolproof structure and magnetic identification, supporting plug and play. The dual wireless communication units support remote control. The functional modules include gas detection, audible and visual alarm, relay routing and power backup modules.
It achieves modular expansion without downtime maintenance, is suitable for complex industrial environments, supports plug-and-play, has flexible networking capabilities, and is applicable to various gas detection scenarios in both industrial and civilian applications.
