Grain Depot Security Application

Background

Grain depots are widely used for grain collection, storage, and transfer. Traditional mechanical padlocks suffer from scattered key management, loss or duplication risks, and no traceable door access records. Manual inspections consume about 35% of total warehouse management hours. Weighbridge operations face cheating such as incomplete weighing, plate swapping, and bypassing the scale — causing inventory discrepancies and economic losses.

HHDlink‘s grain depot security application provides electronic, visualized management for sealing, weighing anti-cheat, and traceability in grain depot operations.

Solution Overview

This application fits grain depot warehouse doors and weighbridge scenarios. It uses smart lock technology to replace traditional mechanical padlocks for electronic door control and weighing-linked management.

• When vehicles enter or exit for weighing, the system automatically verifies vehicle and lock status. Weighing data and sealing records are bound in real time, eliminating plate swapping and scale bypassing
• Supports remote authorized unlocking, with full logs of operator, time, and location
• If the lock is pried or the cable is cut, a tamper alarm is triggered instantly and pushed to the platform
• Supported by the HHDlink Cloud Platform for centralized multi-warehouse lock management, door access logs, weighing data, and vehicle routes — enabling full traceability from inbound to outbound

Ideal For

• Grain collection warehouse door control
• Grain depot weighbridge anti-cheat
• Cross-depot grain transfer
• Inspection door access management
