In industrial scenarios such as mining, electric power, building materials, and chemical engineering, the accuracy and stability of bulk material conveying and metering directly determine the core benefits of enterprises in cost control, trade settlement, and production scheduling.
Traditional electronic belt scales have long been plagued by four major pain points: accuracy drift, cumbersome calibration, deviation-induced measurement errors, and frequent maintenance. Mechanical wear and tension fluctuations cause annual measurement errors to exceed 1%; manual shutdown calibration is time-consuming, labor-intensive and experience-reliant; belt deviation leads to eccentric load errors; and operation and maintenance costs remain high in environments with heavy dust and strong vibration.
Guonuo Technology Class 0.2 High-Precision Intelligent Control Belt Scale deeply integrates AI and hydraulic neural technology to realize full-process automation of calibration - deviation correction - protection, completely freeing manual labor.
The core advantage of Guonuo Technology’s intelligent control belt scale lies in its stable Class 0.2 high precision of ±0.2%, which is directly applicable to high-precision scenarios such as trade settlement. This precision is not an ideal laboratory value; under complex working conditions in large power plants, mines and other sites, it maintains an error fluctuation rate below 0.5% even amid interferences like high-flow impact, material eccentric load and temperature fluctuations.
Its high precision is supported by three core cutting-edge technologies:
1.Full Suspension Matrix Scale Frame DesignAbandoning the traditional lever fulcrum structure, it adopts a trunnion-free and frictionless transmission design, completely eliminating mechanical wear and fulcrum interference. The self-weight of the scale frame is reduced by 20%, and zero-point stability is increased threefold.
2.Distributed Multi-Point Sensing Matrix4 to 8 sets of high-precision digital weighing units are densely arranged along the longitudinal and transverse directions of the belt to form a full metering area perception network. Through multi-dimensional data fusion, it accurately captures subtle changes in material load and eliminates local stress errors caused by eccentric load, vibration and tension variation.
3.High-Precision Digital Sensing & Anti-Interference HardwareSensors adopt IP65 sealed protection, adapting to harsh environments with wide temperature ranges and heavy dust. Combined with strong anti-electromagnetic interference digital processing technology, it ensures stable signal transmission with a data refresh rate of over 50 times per second, capturing dynamic weighing signals at the millisecond level.
AI Online Self-Calibration: Eliminate Manual Operation, Realize Intelligent Closed-Loop Calibration
Traditional belt scales require regular shutdowns for manual calibration using hanging weights and chain weights. This not only consumes time and labor and disrupts production continuity, but calibration results are also easily affected by human operation, with severe accuracy drift occurring between calibration intervals.
Guonuo Technology’s AI online self-calibration technology completely subverts the traditional calibration mode, enabling non-stop, fully automatic and real-time calibration, and building an intelligent closed-loop system of online calibration - dynamic compensation - error correction.
A standard weight bar is integrated into the scale frame. During belt no-load or low-load periods, the system automatically triggers the calibration process: it simulates material gravity via the standard weight bar, compares real-time metering data with standard values through AI algorithms, and dynamically corrects zero point and range parameters to complete online calibration.
Meanwhile, the AI model features continuous self-learning capability, which can real-time identify abnormalities such as zero-point drift and sensor aging, and compensate errors dynamically at the millisecond level without manual intervention, ensuring stable operational precision of the equipment in the long run.
Hydraulic Neural Deviation Correction: Precise Deviation Control to Secure Stable Metering
Belt deviation is the core cause of metering inaccuracy and equipment wear. Traditional manual deviation correction suffers from delayed response and low precision, making it incompatible with high-speed and high-flow conveying scenarios.
Guonuo Technology’s hydraulic neural deviation correction system acts as the "intelligent nerve" of the equipment, enabling real-time perception of belt deviation, millisecond-level response and accurate dynamic deviation correction, eliminating metering errors caused by deviation at the source.
The system consists of displacement sensors, digital hydraulic execution units and an intelligent control module. Perception nodes are fully deployed at the front and rear of the scale body to accurately identify belt offset and material eccentric load.
When belt deviation is detected, the intelligent control module immediately generates the optimal deviation correction instruction to drive the digital hydraulic execution unit, which fine-tunes the angle of the deviation correction roller in real time to correct the belt running track with no manual operation required.
In addition, the system links with the AI weighing algorithm to dynamically compensate slight eccentric load errors that cannot be fully corrected, further improving metering accuracy. In high-load mining working conditions, this technology reduces eccentric load errors by more than 50%, effectively lessens belt edge wear and extends equipment service life.
Supported by the three core technologies of Class 0.2 high precision, AI online self-calibration and hydraulic neural deviation correction, Guonuo Technology’s intelligent control belt scale achieves long-term maintenance-free operation, greatly cutting enterprises’ operation and maintenance costs and management pressure.
The equipment is made of fully sealed, high-strength wear-resistant materials with redundant configuration of key components. Its trouble-free operation cycle exceeds 365 days, and it supports 6-month manual maintenance-free operation, completely breaking away from the traditional operation and maintenance mode of frequent calibration, manual deviation correction and regular overhaul.
