Fixed-Point Stop System for Belt Surface Monitoring of Bulk Material Conveyors — Intelligent Manufacturing by Hezhong Machinery: Guarding the "Main Artery" of Bulk Material Transportation with New Safety Breakthroughs

Foreword

In continuous production of belt conveyors, conveyor belts act as the main artery for bulk material transportation. Their operational safety directly determines production efficiency, personnel safety and corporate benefits. Under traditional operation and maintenance modes, hidden hazards such as belt surface damage, belt deviation and longitudinal tearing can hardly be detected in a timely manner. Besides, the machine stops at random positions once faults occur, which greatly increases troubleshooting difficulty and maintenance duration. Worse still, it may trigger safety accidents and cause multi-layer losses of labor, materials and production capacity.

To tackle prominent industry pain points, the R&D team of Huaibei Hezhong Machinery has focused on tackling core technical challenges and broken through the technical bottleneck of "front-end intelligent computing + precise fixed-point control". We proudly launch the Fixed-Point Stop System with Front-End Computing & Belt Surface Monitoring for Bulk Material Conveyors. Replacing cloud computing with local front-end computing, the system realizes full-dimensional real-time monitoring, millisecond-level early warning response and automatic fixed-point shutdown, building an efficient, reliable and robust intelligent safety defense line for bulk material transportation.

1. Solving Core Pain Points & Restructuring the Safety System for Bulk Material Transportation

Bulk material transportation features dusty environments and harsh working conditions. Conveyor belts operate under heavy loads for a long time, leading to hidden risks that develop rapidly and remain hard to identify. Traditional maintenance modes face multiple safety dilemmas:

1. Delayed Fault Detection Inspection relies on manual patrols, making it difficult to capture early signs including belt surface abrasion, tearing, fastener damage and deviation. Minor hidden dangers often escalate into belt breakage, material accumulation and even serious safety incidents.
2. Vague Fault Positioning The conveyor halts randomly after faults emerge. Maintenance crews spend excessive time locating fault points, leading to passive response and inefficient disposal, which severely disrupt continuous production.
3. High Operation & Maintenance Costs Manual patrols require heavy labor and leave many blind monitoring zones. Troubleshooting and repairs consume plenty of manpower and time. Coupled with equipment wear and production losses from downtime, overall maintenance costs remain high.
4. Severe Safety Risks Belt surface failures including material leakage, scraping, longitudinal tearing and belt breakage directly damage equipment and threaten worker safety, failing to meet standardized safety production requirements.

2. Groundbreaking Safety Upgrades: Three Enhanced Core Capabilities

Centered on front-end intelligent computing, Hezhong Machinery integrates high-precision sensors, AI visual recognition, accurate positioning and automatic control technologies. The whole process of data collection, analysis and decision-making is processed locally on equipment, eliminating reliance on cloud networks and forming a closed loop of perception, judgment and control. This brings systematic breakthroughs in safety protection performance.

2.1 Full-Dimensional Real-Time Monitoring for Early Detection & Rapid Disposal

Equipped with industrial line-scan cameras, white light sources, high-definition industrial cameras, laser sensors, temperature sensors and an active belt deviation correction system, the system performs all-round, blind-spot-free scanning of belt operating status. Our core independent innovation lies in the self-developed front-end computing module: monitoring data is processed locally with high-speed AI identification without cloud upload. It captures abnormal features such as abrasion, tearing, holes, loose belt fasteners and deviation within milliseconds, and supports multi-cycle comparative analysis to identify early hidden hazards in advance.

The monitoring and analysis functions run stably even under extreme underground conditions with weak or completely disconnected network signals, with zero response delay. Monitoring data is synchronized to the surface central control room in real time, forming dual safeguards of local front-end computing and cloud visual management. Acoustic and light alarms are triggered simultaneously to inform maintenance staff of fault types and locations instantly, preventing risks from expanding at the source.

2.2 Precise Fixed-Point Shutdown for Zero-Delay, Full-Coverage Safety Disposal

This represents another key technological breakthrough by Hezhong’s R&D team. The system embeds a high-precision positioning module with positioning accuracy within 5 meters, tracking belt movement and fault locations in real time while seamlessly linking with the front-end computing module. Once abnormalities are confirmed, automatic accurate shutdown commands are issued within 1 second to stop the belt at preset maintenance areas without manual intervention.

Compared with traditional cloud computing solutions, the system improves response efficiency by over 80%, fundamentally solving the long-standing industry problem of random fault shutdown and slow disposal. Maintenance crews can directly head to designated positions for repairs, drastically cutting troubleshooting and maintenance time and minimizing production losses from downtime. In addition, users can manually adjust shutdown positions to fit various maintenance scenarios, enabling more accurate and efficient safety disposal.

2.3 Intelligent Linked Control to Build Multi-Layer Safety Defenses

The system seamlessly connects with existing central control systems of belt conveyors to realize data sharing and coordinated control. For critical faults such as longitudinal tearing and belt breakage, emergency shutdown is activated immediately to cut power and stop accidents from worsening. For minor abnormalities including slight abrasion or deviation, early warning prompts are sent first; if no handling action is taken, the system will gradually reduce operating speed and shut down the machine, balancing safety and continuous production.

Built on front-end and edge computing architectures with 5G wireless communication, the system completes on-site AI analysis and instant local decision-making without cloud network restrictions. Monitoring, early warning and control commands remain fully functional even with underground network outages, eliminating safety blind spots caused by network lag or disconnection. The front-end computing module supports local data storage; all records are automatically synchronized to the cloud once network service resumes, ensuring complete and traceable safety data.

3. Labor Reduction, Efficiency Improvement & Cost Cutting: Intelligent Safety Power for Digital Transformation

The system automates full-process belt monitoring and control, largely replacing traditional manual patrols. A single conveyor belt can save around RMB 180,000 in labor costs annually. Early hazard identification and precise fixed-point maintenance greatly reduce maintenance frequency and expenses, extend the service life of belts and spare parts, and effectively cut production losses caused by downtime.

The system supports local storage and cloud synchronization of historical data, recording total belt runtime, fault categories, fault locations and maintenance logs to provide solid data support for maintenance management and production scheduling optimization. Supported by high-efficiency front-end computing, real-time data statistics and intelligent analysis are available, advancing belt conveyors toward intelligent, unattended operation and providing robust technical support for industry-wide smart upgrading.

Robust Adaptability for Stable Performance Under Extreme Working Conditions

Designed with industrial-grade protection to adapt to underground environments featuring heavy dust, high humidity, strong vibration and drastic temperature fluctuations, all system hardware is dustproof, waterproof, shock-resistant and high-temperature resistant. The front-end computing module adopts military-grade protection technology with over 99.9% stable operation rate and low maintenance demand. The system flexibly fits main transport belts, auxiliary transport belts, long-distance conveyors and steep-angle transportation scenarios. The front-end computing module can be flexibly calibrated according to belt length and speed to satisfy diverse working condition requirements.
