Project Background
A cold chain logistics company needed continuous monitoring for food, fresh goods, and medicine shipments. The previous process relied on manual driver records and offline device exports, making it difficult to connect temperature exceptions, door-opening records, vehicle locations, and shipment batches.
Applicable Scenarios
This case is suitable for Logistics and Cold Chain projects that need to unify offline processes, device data, user operations, and management reports. If an enterprise already has partial systems, the project can start from high-frequency workflows or critical devices and then expand gradually.
Client Requirements
- Manage transportation tasks by vehicle, container, shipment batch, and customer.
- Collect temperature, humidity, door sensor, and location data throughout transportation.
- Trigger alerts for temperature excursions, humidity anomalies, long offline periods, or abnormal door opening.
- Provide traceability reports for customer inquiry, internal review, and compliance preparation.
Technical Solution
The project combined IoT acquisition, transportation task management, and traceability reporting. Instead of displaying isolated sensor values, the platform linked devices, vehicles, batches, and goods to help teams locate affected shipments quickly.
- Designed data models for vehicles, containers, sensors, and shipment batches.
- Connected temperature, humidity, door sensor, and location data through gateways or mobile networks.
- Configured threshold rules, alert levels, and notification recipients.
- Provided route records, temperature curves, exception logs, and batch report exports.
System Functions
- Vehicle and container profiles, sensor binding, shipment batch creation, and status tracking.
- Real-time temperature curves, historical query, exception alerts, and handling records.
- Traceability reports by customer, batch, goods, and time period.
- Expandable APIs for order, warehouse, or customer service systems.
Data and Security Design
- Define permissions for administrators, business users, maintenance staff, and external collaborators.
- Keep operation logs for important business actions to support tracing, audit, and review.
- Use authentication, parameter validation, and clear error responses for external APIs.
- Support backup, export, and conditional query for important data to simplify long-term maintenance.
Implementation Process
Implementation started with shipment batch rules, vehicle binding, and device binding. The team validated data caching in weak networks, threshold accuracy, report completeness, and access permissions before launch.
Acceptance Focus
- Core workflows can run through creation, processing, query, and archive.
- Key data fields match the client's business definitions and report results can be reviewed.
- Mobile, backend, and API data remain consistent with clear exception messages.
- Deployment, account permissions, operation instructions, and maintenance methods are delivered clearly.
Delivery Results
- Cold chain transportation records moved from offline files to online monitoring.
- Exceptions can be reviewed by time, vehicle, batch, and device.
- Customer traceability requests no longer depend on manual consolidation.
- The platform reserved interfaces for warehouse, order, and customer service integration.
Project Boundary
This is an anonymized industry case focused on project type, technical route, and delivery method. Real implementation should be evaluated against the client's existing systems, devices, workflows, permissions, and maintenance conditions.
Reusable Experience
Cold chain projects must link sensor data with real shipment batches. Key early decisions include thresholds, alert owners, installation positions, offline upload rules, and traceability report fields.

FAQ
Which cold chain scenarios fit this case?
Food, fresh goods, medicine, lab samples, refrigerated distribution, and cross-region transportation that require continuous temperature records.
Must existing sensors be replaced?
Not usually. Existing devices can be reused if their protocols, export methods, and connectivity support integration.
Can traceability reports be customized?
Yes. Reports can combine batch data, customer data, goods, route, temperature curves, and exception records.
