I. Introduction to the Online Inspection System for Disc Brakes
The disc brake online monitoring system is an intelligent safety monitoring solution specifically developed for critical equipment such as mine hoists, port machinery, and rail transit systems. Utilizing multi-sensor fusion combined with AI analysis technology, the system continuously monitors key parameters like brake friction coefficient, brake shoe wear, and hydraulic pressure in real time, enabling early fault detection, performance evaluation, and lifespan prediction. This proactive approach effectively prevents brake failure incidents, ensuring reliable equipment operation.
II. System Components
1. Core Detection Unit
Detection Module
Friction Coefficient Monitoring: Real-time measurement of the friction coefficient between brake disc and brake pad, enabling identification of performance degradation.
Brake shoe wear detection: Laser ranging + thickness sensor for precise measurement of remaining wear.
Hydraulic Pressure Monitoring: High-precision pressure sensors monitor fluctuations in brake oil pressure.
Temperature Monitoring: Infrared Temperature Measurement + Contact Sensors to Prevent Brake Overheating
Vibration Analysis: Acceleration sensors detect abnormal vibrations, providing early warnings of mechanical failures.
2. Intelligent Analysis Platform
Edge Computing Terminal: Real-time data processing on-site, with response time under 50ms
AI Diagnostic Algorithm: Building a Brake Performance Degradation Model Based on Machine Learning
Cloud Platform: Supports data storage, remote access, and multi-device management
3. Human-Machine Interaction Interface
Local HMI touchscreen: Displays braking status and alarm information in real time
Remote Monitoring Center: View data via Web/APP, with support for exporting PC-side reports.
III. Core Features
1. Real-time Status Monitoring
24/7 continuous monitoring of 12 key parameters
The sampling frequency can reach up to 1000 Hz (dedicated for vibration analysis).
2. Intelligent Early Warning System
Alarm Type | Trigger Condition | Response Measures
Emergency braking: Friction coefficient <0.35 or abnormal oil pressure—automatic activation of backup brake + shutdown
Level 1 Alert: Brake shoe wear reaches 80% or temperature exceeds the limit—indicating a planned replacement is recommended.
Level 2 Warning: Performance Decline of 20% or Abnormal Vibration—Maintenance and Inspection Recommended
3. Diagnostic Function
Remaining Useful Life Prediction: Calculating Brake Shoe Replacement Cycles Based on Wear Rate
Brake Performance Evaluation: Generating Brake Distance-Speed Characteristic Curves
Fault Tree Analysis: Automatically Identifies the Root Cause of Failures (Hydraulic/Mechanical/Electrical)
4. Data Management
10-Year Data Storage (Scalable)
Supports automatic generation of ISO 12100 safety standard compliance reports
IV. Technological Advantages
Traditional detection methods, this online detection system
Manual periodic measurements with long intervals—real-time continuous monitoring, eliminating any detection blind spots.
Relying on experiential judgment leads to significant errors, whereas AI-powered quantitative analysis achieves an accuracy of ±1%.
Unexpected failures cannot be predicted—provide early warnings of potential risks 3 to 7 days in advance.
Decisions unsupported by historical data, full lifecycle data traceability
Shutdown detection impacts production—online detection ensures zero production disruption.
V. Typical Applications
Monitoring of Braking System for the Main Shaft Hoisting in a Metal Mine
Question: Previously experienced an overwinding accident due to brake shoe failure.
Solution: Install an 8-channel online inspection system
Effect: Achieved 3 early warnings, preventing major accidents and extending the brake shoe replacement cycle by 30%.
