The Hezhong Cloud Smart Tool Cabinet upgrades traditional safety tool cabinets with intelligent access control, tool management and test-cycle management. It supports face recognition and fingerprint unlocking, infrared or RFID positioning of tools, test-date reminders and heating/dehumidification. Collected data is uploaded to a big-data cloud platform for real-time visibility of tool inventory, borrowing/return records, environmental conditions and overdue test reports, improving safety-tool management and reducing O&M cost.
