Smart Reefer Telematics and Truck Temperature Tracking

Reefer Truck Telematics and Temperature Tracking

Yuwei’s “Trailer Temperature Monitoring” solutionprovides real-time temperature tracking and alert services. It supports monitoring up to three temperature zones inside the trailer, ensuring each zone remains within the preset range. In case of any anomaly, users are instantly notified via desktop or mobile. The system complies with FSMA (Food Safety Modernization Act)transportation standards, helping fleets prevent perishable goods loss and enhance delivery safety and compliance.

Basic Hardware Configuration List

Yuwei’s fleet monitoring system is built on four core hardware components, forming the foundation for temperature monitoring:

1. 4G Smart Camera (ADAS + DSM)

①　Captures real-time footage of the driver’s cabin to detect fatigue, distraction, or smoking.

②　Temperature Monitoring Compatibility:Supports external temperature display for real-time cargo temperature feedback.

2. Blind Spot Camera (BSD)

①　Monitors the right-side blind area for pedestrians or obstacles and triggers audible and visual alarms.

②　Temperature Monitoring Compatibility:Can be equipped with a waterproof temperature probe to monitor loading/unloading area temperature.

3. HUD Head-Up Display

①　Projects vehicle speed and alerts onto the windshield.

②　Temperature Monitoring Compatibility:Displays temperature warning messages.

4. Vehicle DVR Main Unit

①　Records 1080P HD video with event-triggered recording capability.

②　Temperature Monitoring Compatibility:Built-in temperature data interface for synchronized temperature curve storage.

Temperature Monitoring Hardware Extension Plan

By adding the following modules to the base configuration, full temperature monitoring capability is achieved:

1. Cold Chain Temperature Sensor

①　Probe Type: NTC thermistor

②　Technical Advantages: -20°C to +60°C wide range, ±0.3°C high accuracy

2. LoRaWAN Wireless Transmission Node

①　Low-power, long-range communication with strong signal penetration

②　Application: Full coverage within refrigerated trailers; supports multi-node networking

3. Redundant Power Module

①　Dual power supply (main + backup battery)

②　Core Value: Continuous monitoring for over 12 hours after engine shutdown

4. Anti-Vibration Data Concentrator

①　IP67-rated protection, supports CAN bus / RS485 protocol

②　Designed for high-vibration cold chain vehicle environments

Intelligent Cold Chain Management Closed-Loop Process

1. Pre-Alert Phase

①　The onboard DVR continuously compares sensor data with preset temperature thresholds.

②　If exceeded, it triggers three levels of alarms (local buzzer → app notification → SMS alert).

2. Incident Handling Phase

①　The management platform automatically retrieves event-time video footage.

②　ADAS image recognition assists in diagnosing root causes (e.g., door not closed causing temperature fluctuation).

3. Post-Event Traceability

 Automatically generates time-stamped temperature compliance reports, exportable in PDF/Excel formats, meeting regulatory audit requirements.

Typical Application Scenarios

1: Fresh Food Delivery

①　Loading at Dawn:Driver scans batch QR code; system logs initial temperature.

②　In-Transit Monitoring:Temperature and humidity data uploaded every 5 minutes; deviations trigger recording for evidence.

③　Delivery Verification:Receiver scans to confirm temperature curve; disputed data traceable to original footage.

2: Vaccine Transportation

①　Multi-Zone Control:Simultaneously monitors dry-ice containers (-20°C) and constant-temperature boxes (2–8°C).

②　Emergency Response:Automatically contacts the nearest backup cold storage if extreme temperature persists for over 5 minutes.

Advantages of Yuwei Cold Chain Monitoring System

1. Modular Design:Supports hardware customization; legacy devices can connect quickly via OBD interface.

2. Edge Computing Capability:Onboard DVR performs local data preprocessing, reducing bandwidth usage by 70%.

3. Ecosystem Compatibility:Seamless integration with mainstream ERP systems; API development supported.
