III. Core Working Principle
After a vehicle enters the weighing zone, the system automatically triggers the weighing process via ground loop detection, infrared light curtains, license plate recognition and RFID identification. It accurately verifies whether the vehicle is positioned correctly on the weighbridge and prevents irregularities such as wheel overlapping the edge, off-center parking and multiple vehicles on the scale simultaneously.
Weighing sensors collect weight signals in real time and transmit them to the weighing software. The system automatically conducts data parsing, filtering calibration and anti-interference processing, and displays precise weighing data on a real-time basis.
Once compliant weighing is completed, the system automatically records full-dimensional data including gross weight, tare weight, net weight, vehicle information, timestamp, material type and operator information, and performs synchronous data archiving and snapshot evidence preservation. It automatically decides on release according to preset rules, triggers coordinated actions of barrier gates, traffic lights and voice prompts, and prints weighing receipts on demand. The whole process requires no manual intervention and enables standardized unattended weighbridge operations.
IV. Core Product Functions
1. Multi-Dimensional Anti-Cheating via Hardware-Software Coordination for Zero Measurement Loopholes
The system adopts a complete intelligent anti-cheating framework with dual protection from hardware monitoring and software algorithms to fully block all types of weighing fraud.

It supports intelligent self-diagnosis, exception alerts, violation logging and full-process video traceability. Combined with multi-level account permissions, permanent retention of operation logs and encrypted data storage, it prevents manual tampering, repeated weighing, false weighing and license plate swapping. The whole weighing process becomes fully searchable, traceable and accountable.
2. Full-Process Unmanned Operation for Maximum Cost Reduction and Efficiency Improvement
The system integrates weighing, vehicle control, weighhouse supervision, data statistics and ledger management to complete all weighbridge operations in a standardized, streamlined and intelligent manner. It completely replaces dedicated weighmasters and eliminates on-site staffing requirements, enabling round-the-clock unmanned continuous operation and significantly cutting labor, management and shift scheduling costs. Meanwhile, it simplifies weighing workflows, shortens vehicle waiting time and boosts site traffic and measurement efficiency, suiting scenarios with large-volume, high-frequency material inbound and outbound movements.
3. Multi-Scale Linkage to Maximize Equipment Utilization
A single software instance can bind multiple truck scales. It supports split tare/gross weighing for the same vehicle at different sites, automatically matches historical tare records, updates weighing ledgers in real time and intelligently validates data rationality. Real-time synchronization and centralized aggregation of data across multiple scales enable multi-station collaborative operation, avoiding congestion and idling of individual weighbridges. This greatly raises equipment utilization and reduces redundant capital expenditure on weighing instruments.
4. Intelligent Reporting System for Visualized Data Management
Built-in standardized report templates support custom query and statistics by hour, day, week, month or year. It generates various reports such as weighing details, material summaries, vehicle statistics, revenue/expenditure ledgers and exception records. Reports can be previewed, printed and exported as Excel or PDF files; custom templates are also available to satisfy enterprise reconciliation, settlement and audit requirements.
New graphical data analysis automatically generates bar charts, line charts and other visualizations to clearly display material throughput, weighing frequency and equipment status, providing data support for production scheduling, inventory control and cost accounting. Data can be automatically pushed over internal or external networks to designated department terminals to realize paperless data circulation.
5. Intelligent Identification and Voice Prompts for Zero-Threshold Operation
Dual identification modes are integrated: high-definition automatic license plate recognition and RFID card recognition, delivering high accuracy and compatibility with all types of freight vehicles. Full-process voice prompts guide drivers to mount the scale, wait, weigh and exit, with automatic voice alerts for anomalies. Drivers do not need to alight, making the workflow simple and efficient for operators of all skill levels.
6. Full-Dimensional Data Traceability and Secure Evidence Preservation
All weighing data, vehicle information, captured images, operation records and exception logs are encrypted and retained permanently in non-tamperable form for instant retrieval and traceability. Fuzzy search supports quick data matching via keywords such as plate number, material name, customer entity and time range, resolving the inefficiency of manual ledger lookup and cumbersome reconciliation.
