Can I connect the demodulator data directly to my large screen monitoring system?
Yes. Integrating data from Fiber Bragg Grating (FBG) interrogators into large-screen monitoring systems (such as SCADA, DCS, Industrial IoT dashboards, or Web front-end visualization platforms) is a standard integration application in modern engineering monitoring.
The key to achieving seamless integration between the interrogator and the large-screen monitoring system lies in the standardized data interfaces and communication protocols supported by the interrogator.
I. Common Data Integration and Connection Paths
-
Industrial and Network Communication Protocol Integration (TCP / UDP / Modbus)
- TCP/IP / UDP Sockets: The interrogator, acting as a server or client, pushes wavelength or physical quantity data (temperature, strain, etc.) to the data acquisition service of the large-screen system at regular intervals, using a predefined data frame format (e.g., hexadecimal or JSON data packets).
- Modbus TCP: In industrial control dashboards, the interrogator can function as a Modbus slave device, mapping real-time values from each measurement point to register addresses (Holding Registers) for the host system or large-screen system to poll and read.
-
Software Architecture and Web Visualization Integration (B/S Architecture)
- WebSocket / RESTful API: For modern web monitoring dashboards built with front-end technologies (such as Vue, React, ECharts, Three.js, etc.), the interrogator’s backend software can directly provide HTTP APIs for querying or utilize WebSocket for full-duplex, millisecond-level low-latency data streaming.
- Database Synchronization: The interrogator’s accompanying software continuously stores the parsed physical quantities from each channel into a local or remote relational/time-series database (e.g., MySQL, SQL Server, InfluxDB, etc.). The monitoring dashboard system then directly connects to the database for data retrieval and chart rendering.
-
Secondary Development Interfaces (API / SDK)
- System integrators can embed the interrogator’s API or dynamic link libraries into their own host software. This allows for direct control over channel activation/deactivation and high-frequency raw wavelength data acquisition. After filtering through business algorithms, the data can be pushed to the large-screen display.
II. OFSCN® Fiber Bragg Grating Interrogator Technical Support
Beijing Dacheng Yongsheng Technology Co., Ltd.'s official product, the OFSCN® Fiber Bragg Grating Interrogator, natively supports the aforementioned system-level standardized interface integration:
- Software Architecture: Defaults to B/S architecture software, also supporting C/S architecture software, facilitating cross-platform access and embedding within the network.
- Communication Protocols: Supports seamless integration with third-party monitoring systems, industrial control software, or large-screen systems via standardized protocols such as TCP, UDP, and Modbus.
- Data Sampling Characteristics: Data sampling frequencies of 10 Hz, 50 Hz, and 100 Hz are available (users can configure within the interrogator software between 1 Hz and the rated sampling rate as needed). This facilitates matching the refresh rate requirements of the large-screen system and prevents high-frequency data from blocking network buses.
- Physical Channel Specifications: Available in 4, 8, 16, or 32 channels; the default wavelength range is 1525 nm to 1565 nm (or 1528 nm to 1568 nm, customizable).
