IOT News

In traditional cold chain logistics, transportation companies have long faced the "black box" problem: since vehicles are constantly moving, managers cannot obtain real-time temperature and humidity data inside the cargo compartment. They have no way of knowing whether the refrigeration unit is operating properly or whether unusual temperature fluctuations are occurring. Often, these issues are only discovered after the goods have been delivered. This delay means that if equipment fails or temperature control is lost during transit, an entire shipment may spoil or become damaged, resulting in significant financial losses.

Therefore, the core requirement for cold chain transportation companies is to build an intelligent in-transit monitoring system that can: continuously track vehicle status 24/7, automatically alert for abnormal conditions, support remote emergency intervention, and generate compliance audit reports. To address this, WideIOT provides a highly reliable and efficient IoT solution.

WideIOT's industrial intelligent gateway connects the refrigeration unit's PLC controller, temperature and humidity sensors, and motor monitoring modules via RS232/RS485 serial ports and Ethernet ports. It collects critical data in real time, including multi-point temperature and humidity inside the cargo compartment, compressor operating frequency, voltage and current, and vehicle location. This data is then securely encrypted and uploaded via 5G/4G wireless networks to the company's private cloud monitoring center. This enables remote monitoring, alerting, management, statistical analysis, and reporting, helping cold chain logistics transition from experience-based management to digital control.

Key Features

1. Real-Time Monitoring

Monitor in-cargo temperature and humidity, real-time cargo location (position and route), and vehicle speed/mileage. This provides comprehensive, real-time data support for cold chain logistics management.

2. Centralized Visibility

View real-time status for single or multiple vehicles through a platform interface, clearly showing temperature compliance, location distribution, driving routes, and more. Accessible for remote monitoring via both mobile and PC.

3. Automated Alerts

Set custom alert rules. Alerts are automatically sent via SMS, WeChat, or email, clearly indicating which vehicle is affected and the abnormal values. This helps managers quickly identify issues and take immediate action.

4. Reporting and Analytics

Query vehicle trip records, temperature/humidity trends, and alert handling details. Generate single-vehicle transport reports or multi-zone logistics efficiency comparison charts to help optimize delivery routes and refrigeration strategies, ultimately reducing operating costs.
