In this application, BL192 modules are installed in electrical cabinets within subway control rooms and utility spaces. They are connected to lighting circuits and ventilation fans through digital I/O channels. In some cases, analog input modules are also used to collect environmental sensor data such as temperature, humidity, and CO₂ levels.
All collected data including device status, voltage, current, and execution feedback is transmitted in real time to the centralized smart city management platform via the MQTT protocol. The platform supports full visualization, remote control, and alarm notifications.
Quick Deployment: DIN rail mounting and web-based configuration ensure fast setup;
Stable Communication: Dual Ethernet ports with MQTT, DHCP, and DNS support ensure reliable data transmission;
Edge Intelligence: Built-in logic control enables local automation such as “auto-start fan when temperature is high” or “dim lights in energy-saving mode at night”;
Remote Maintenance: Supports BLRAT (Beilai Remote Access Tool) for firmware upgrades and remote diagnostics;
Industrial Durability: Operating temperature range from -40°C to 85°C with full EMC/EMI protection, ideal for complex subway environments.
Full Visibility: Real-time equipment status displayed on the platform;
Intelligent Maintenance: Data-driven maintenance planning and energy optimization;
Faster Fault Response: Immediate alarm notifications enable quick action;
Cloud Integration: MQTT integration with the city platform enables unified monitoring across the subway and other infrastructures.
With the deployment of the BL192 Edge I/O Module, subway stations achieve a smart O&M system that connects scattered field devices to the cloud, enabling transparent status monitoring, automated control, and centralized management. Beilai Technology will continue to empower urban infrastructure with edge computing and IoT innovation, accelerating the realization of smart city goals.
