Remote Management: BLRAT remote access tool facilitates device maintenance, reducing on-site operational costs.
Rapid Development: Integrated Node-Red enables quick development of IoT applications, simplifying data visualization and logic control.
Typical Application Scenarios in Boiler Monitoring
The BL310 can implement the following core functions in boiler monitoring:
Temperature Monitoring: Uses Y51/Y53 (PT100/PT1000) or Y58 (thermocouple) boards to measure boiler water and flue gas temperatures.
Pressure Monitoring: Acquires pressure sensor data via Y31/Y33 (4-20mA or 0-10V).
Flow Monitoring: Monitors fuel or water flow using Y95/Y96 (pulse counting).
Status Control and Alarms: Implements switching control and alarm outputs via Y01/Y02 (DI/DO) or Y24 (relay) boards.
Remote Monitoring: Transmits data to cloud platforms via 4G/WiFi modules and MQTT protocol for real-time boiler status monitoring.
Data Analysis: Leverages cloud platforms for historical data storage, trend analysis, and energy optimization.
Recommended Configuration
To meet boiler monitoring requirements, the following BL310 configuration is recommended:
Model: BL310L-SOM314-X4-Y51-Y24
Host: BL310L (with 4G module for remote monitoring).
SOM Module: SOM314 (512MB DDR3L, 8GB eMMC, -40~85°C, suitable for high storage and wide temperature needs).
X Board: X4 (2x RS485 + 2x CAN, for connecting to PLCs or other devices).
Y Board 1: Y51 (2-channel 3-wire PT100 for precise temperature monitoring).
Y Board 2: Y24 (4-channel relay output for controlling alarms or valves).
Software Configuration:
Pre-installed BLIoTLink and BLRAT, supporting Modbus-to-MQTT conversion and integration with Thingsboard or AWS IoT Core.
Node-Red for developing data dashboards to display real-time temperature, pressure, and other parameters.
Implementation Suggestions
4.1 Hardware Installation
Install the BL310 in the boiler control cabinet using DIN35 rail mounting, ensuring proper grounding via the 1-pin GND terminal.
Use a 24VDC power supply (supports 9-36V wide voltage range) with reverse polarity and overcurrent protection for enhanced safety.
Configure WiFi/4G antennas as needed to ensure stable signal transmission.
4.2 Software Development
Use Node-Red to quickly develop data acquisition, alarm logic, and visualization dashboards.
Configure BLIoTLink to collect Modbus RTU/TCP data and transmit it to the cloud via MQTT.
Set up BLRAT for remote access, enabling maintenance personnel to monitor device status in real time.
4.3 Testing and Validation
Conduct high/low-temperature and electromagnetic compatibility tests before deployment to ensure reliability in boiler room environments.
Refer to technical support’s Node-Red and BLIoTLink development examples for rapid function validation.
Test 4G/WiFi connection stability to ensure uninterrupted data transmission.
Precautions
I/O Board Selection: Note that Y63 (4x RS485/RS232) occupies two Y slots, preventing the addition of a second Y board.
Storage Needs: For large historical data storage, choose SOM314 (8GB eMMC) over SOM310 (256MB Nand).
Network Security: Configure MQTT authentication and encryption to prevent data breaches.
Custom Development: For special requirements (e.g., vibration monitoring), contact Beilai Technology for customization (see Technical Support section).
