Jinyun Unattended Weighing System and Laser Weighbridge Equipment Deployed at a Construction Site in Sichuan

Intelligent Weighing Management Upgrade Boosts Efficiency and Reduces Costs for Construction Sites

Recently, Jinyun Technology’s unattended anti-cheating weighing system, paired with laser weighbridge equipment, has completed installation and commissioning and officially entered operation at an earthwork construction site in Sichuan. Addressing pain points such as complex open-air working conditions, low weighing efficiency, high labor costs for metering, and vulnerabilities to weighing fraud, this integrated intelligent weighing solution leverages a fully proprietary technology system and industrial-grade hardware configuration to realize fully unmanned, high-precision, and highly stable operation of the vehicle weighing process, delivering significant efficiency improvements to on-site project management.

Tailored Intelligent Solution Addresses On-Site Pain Points

Traditional construction site weighbridges mostly rely on manual on-site operation, which not only suffers from low efficiency and causes vehicle queuing and congestion, but also experiences frequent equipment failures due to open-air dust and temperature fluctuations. Meanwhile, manual operation brings management loopholes such as metering errors, falsified weigh records, and difficult data traceability, becoming a major challenge for project cost control.

Targeting the actual operating scenarios of this Sichuan construction site, Jinyun Technology customized and deployed a combined solution of "unattended weighing system + laser weighbridge", with all-round optimization from system 底层 architecture and hardware configuration to environmental adaptability, realizing the intelligent upgrade of the entire weighing and metering process.

Fully Proprietary Industrial-Grade System Ensures Stable Operation

The Jinyun unattended weighing system adopted in this project features a fully self-developed industrial-grade embedded Linux system architecture, which is free from crashes, freezes and data loss, and achieves 100% stable operation, completely eliminating risks such as system downtime and data abnormalities common in ordinary systems.

For power supply, the system adopts a DC 12V/10A DC power supply scheme with a total power consumption of only 80W. This low-power design ensures both safety and energy efficiency, making it highly adaptable to field scenarios without stable mains power. Combined with a power-off data protection mechanism, it guarantees the integrity of metering data throughout the process.

Full-Scene Environmental Adaptation for All-Weather Outdoor Operation

The equipment is specially designed for fully outdoor open-air scenarios with high protection performance, and withstands harsh working conditions including dust, rain, snow, strong sunlight and extreme temperatures. It covers an operating temperature range of -30℃ to 60℃, adapting to the climate changes of hot summers and cold winters in Sichuan. Customized adaptation is also available for extreme high/low temperature environments to ensure stable operation all year round.

Patented LiDAR for High-Precision Metering and Anti-Cheating Protection

The supporting laser weighbridge is equipped with patented LiDAR with a scanning distance of up to 60 meters, outputting 500,000 point cloud data per second and supporting high-precision 3D modeling. It can accurately measure the loading volume of vehicles and perform linkage verification with weighing data. The system provides optional measurement accuracy of <1%, <2% and <3% to meet high-standard metering acceptance requirements; adopting a high-precision static measurement mode, it delivers stable data output with minimal error, effectively guaranteeing metering accuracy.

Meanwhile, the system is matched with 1600×1200 high-definition full-color cameras, supporting 24-hour color HD capture and recording with clear, noise-free night images. Each weigh-in record is synchronously bound with vehicle image, timestamp, weight/volume data, leaving full traceable records and technically eliminating weighing fraud loopholes.

Efficient Traffic and User-Friendly Interaction Significantly Improve Weighing Efficiency

The solution supports continuous vehicle passage and 24/7 uninterrupted weighing operations, running reliably all year round. It greatly shortens vehicle waiting time and solves the problem of vehicle queuing during peak hours at the construction site. The site is equipped with outdoor high-brightness LED displays, which keep data clearly visible even under direct sunlight. Drivers can view real-time weigh-in data without getting off the vehicle, enabling convenient and efficient interaction.

The successful deployment of Jinyun’s unattended weighing system and laser weighbridge equipment at the Sichuan construction site marks another practice of Jinyun Technology in the field of intelligent metering for infrastructure construction. Going forward, Jinyun Technology will continue to deepen its expertise in industrial weighing and volume metering technology, and empower more mines, construction sites and sand & gravel yards to achieve digital upgrading of metering management with more stable, accurate and harsh-environment-adapted intelligent solutions.
