Case Details
Gear boxes are the core power transmission components in industrial equipment such as motors, conveyors, and wind turbines. Their stable operation directly determines production efficiency and equipment safety. However, traditional gear box maintenance relies on regular inspections and manual monitoring, which often fail to detect early faults (such as wear, lubrication degradation, and bearing damage) in a timely manner, leading to unexpected shutdowns, high maintenance costs, and even safety accidents.
With the deepening of industrial digital transformation, intelligent monitoring has become the key to solving gear box operation and maintenance pain points. The
BLIIOT Gear Box Intelligent Monitoring Solution, built around the BL116 high-performance edge gateway and
BL118 Node-RED edge gateway, integrates multi-dimensional data acquisition, real-time analysis, and remote early warning capabilities. It realizes full-life-cycle management of gear boxes from "passive maintenance" to "predictive maintenance", effectively reducing failure rates and optimizing operation and maintenance efficiency.
Core Architecture: Hardware Foundation + Intelligent Algorithm
The solution relies on BLIIOT's industrial-grade edge gateways as the core, matching with professional sensors and cloud platforms to form a three-tier architecture of "perception layer - edge layer - cloud layer", ensuring comprehensive, real-time, and reliable gear box monitoring.
1. Perception Layer: Multi-Dimensional Data Acquisition
Targeting the key failure factors of gear boxes, the perception layer deploys a full set of professional sensors to capture critical operating data:
- Vibration Sensors: Connected via RS485/CAN interfaces, monitoring vibration acceleration, velocity, and displacement of gear boxes (supporting IEPE signal acquisition), which can identify early faults such as gear wear, bearing pitting, and shaft misalignment.
- Temperature Sensors: Adopting PT100/PT1000 RTD and K/J-type thermocouples, real-time monitoring of gear box oil temperature, bearing temperature, and casing temperature to prevent overheating caused by poor lubrication or overload.
- Oil Quality Sensors: Detecting oil viscosity, moisture content, and impurity concentration in gear boxes via analog signals (4-20mA/0-10V), reflecting lubrication status and avoiding wear failures caused by oil degradation.
- Speed & Load Sensors: Collecting rotational speed and load data of gear boxes through pulse signals, analyzing operating conditions and identifying abnormal load impacts.
All sensors support Modbus RTU/TCP, CAN, and other industrial protocols, enabling seamless connection with BLIIOT edge gateways.
2. Edge Layer: Real-Time Processing with Dual Gateway Collaboration
The edge layer adopts the combination of
BL116 and BL118 edge gateways, realizing distributed data processing and intelligent analysis, and solving the pain points of high latency and poor real-time performance of traditional cloud-based monitoring:
