In the environmental protection and water treatment industry, the accuracy and real-time performance of water quality monitoring directly affect pollution control efficiency and water safety. Traditional water quality monitoring systems face core challenges such as low detection precision, delayed data transmission, difficult on-site calibration, and poor multi-parameter integration. This solution, based on the ARMxy BL310 industrial-grade embedded computer (NXP i.MX6ULL + flexible IO configuration), builds an intelligent online water quality monitoring system integrating multi-parameter synchronous collection, edge real-time analysis, intelligent early warning, and remote operation and maintenance. By adopting a sensor data fusion and temperature compensation algorithm, it achieves ±2% full-scale measurement accuracy and <300ms data update frequency. Combined with BLIoTLink, BLRAT, and Node-Red core tools, the solution ultimately reduces manual sampling and calibration costs by 70%+, shortens pollution early warning time by 50%+, and realizes full-process intelligent monitoring of water quality.
- Low Detection Precision: Single sensor measurement lacks compensation, leading to large errors in complex water environments.
- Delayed Data Transmission: Offline sampling and manual reporting result in failure to timely grasp water quality changes.
- Difficult On-Site Calibration: Dispersed monitoring points require frequent on-site calibration, with high labor costs.
- Poor Multi-Parameter Integration: Separate monitoring of pH, dissolved oxygen, turbidity and other parameters, failing to realize comprehensive water quality evaluation.
The ARMxy BL310 + Multi-Sensor Fusion combination delivers four core values for water quality monitoring:
- Flexible IO Expansion: Optional X/Y series IO boards support access to pH, dissolved oxygen, turbidity, conductivity and other sensors.
- Industrial-Grade Stability: -40~85℃ wide temperature range, anti-electromagnetic interference and anti-corrosion design, adapting to harsh water environment monitoring.
- Edge Real-Time Analysis: Local data processing and abnormal judgment avoid network delay impacts on early warning.
- Remote Operation and Maintenance: Support remote calibration, parameter adjustment and fault diagnosis, reducing on-site workload.
Adopting a "cloud-edge-device" three-tier collaborative architecture:
- Device Layer: Multi-parameter water quality sensors (pH, dissolved oxygen, turbidity, COD), temperature compensation modules, collecting water quality raw data.
- Edge Layer: ARMxy BL310 as the core controller, undertaking data acquisition, fusion analysis, and early warning signal issuance.
- Cloud Layer: Realizing centralized data storage, trend analysis, report generation, and remote management.
- Multi-Sensor Data Fusion: Fusing data from multiple sensors and applying temperature/pressure compensation to improve measurement accuracy.
- Edge Abnormal Detection: Pre-set water quality threshold models to realize real-time early warning of abnormal indicators.
- Low-Power Transmission: Optimizing data transmission frequency based on water quality stability to reduce energy consumption.
- Remote Calibration: Through BLRAT tool, realizing remote calibration of sensors and parameter modification.
- Main Controller: ARMxy BL310B (2×10/100M Ethernet ports, 2 Y-board slots)
- Core Board: SOM314 (NXP i.MX6ULL, Cortex-A7, 512MB DDR3L, 8GB eMMC)
- Peripheral Configuration: Multi-parameter water quality sensor suite, temperature compensation module, waterproof data acquisition terminal
- Expansion Module: Y31 AI module (analog data collection), Y63 RS485 module (connecting sensors), Y51 RTD module (temperature monitoring)
- High-Precision Measurement: ±2% full-scale accuracy, meeting national environmental monitoring standards.
- Real-Time Early Warning: <300ms data update, timely capturing abnormal water quality changes.
- Low-Cost Operation: Remote calibration reduces 70%+ on-site workload, lowering operation and maintenance costs.
- Flexible Expansion: Supports access to 8+ water quality parameters, adapting to different monitoring scenarios.
This solution is suitable for:
- Industrial wastewater discharge monitoring (chemical, printing and dyeing, electroplating industries)
- Drinking water source protection monitoring
- Sewage treatment plant process monitoring
- Aquaculture water quality monitoring
- Surface water (rivers, lakes) environmental monitoring
