System Architecture: The OMC system adopts a multi-layer architecture: Sensors: The bottom layer consists of various sensor devices used to collect environmental data; Upper Computer: Used to obtain sensor data and perform preliminary processing, then report it to the backend; Server: Used to receive data uploaded from the upper computer, providing real-time status information of terminal devices to customers and maintenance personnel; Mobile Terminal: Allows management personnel to query/control device status via mobile devices;
Sensor Data Acquisition: The device terminal collects sensor data through the control board. Sensor data includes: temperature sensor, humidity sensor, smoke sensor, water immersion sensor, collision sensor, tilt sensor, door switch sensor, screen front wind speed sensor, etc.;
Upper Computer: Sensor data communicates with the upper computer motherboard via UART serial port. The upper computer sends a data request to the control board every 10 seconds, and the control board sends the current sensor data to the upper computer;
Service Backend: The service backend receives terminal data for data processing and statistics, providing equipment inspection and monitoring functions, as well as remote control, remote settings, and device management operations for backend management personnel. It also includes user and permission registration and management, as well as statistical processing of device alarms.
Mobile Terminal: Mobile devices access backend data through backend interfaces to perform data querying, remote control, remote settings, user management, and device management operations on terminal devices.
