This article delves into the innovative application of industrial-grade mobile computing solutions in extremely low-temperature cold chain storage environments. Through a practical case study of JD Cold Chain, a leading comprehensive logistics service provider in China, this article demonstrates how the AUTOID Q7-(Cold Chain) mobile computer overcomes challenges in data collection and equipment reliability in ultra-low-temperature environments of -22°C. It provides key hardware support for ensuring traceability and operational efficiency throughout the cold chain logistics process.

User Background

JD Cold Chain focuses on fresh food and pharmaceutical logistics, integrating cold chain distribution, transportation, and warehousing capabilities to build a comprehensive cold chain service platform. To provide end-to-end, full-scenario F2B2C one-stop cold chain services, ensuring safe receipt of goods for retailers and consumers, JD Cold Chain, with products as the foundation and technology as the core, constructs a socialized cold chain collaboration network.

Challenges

To meet the market's demand for more precise and high-quality fresh product delivery, JD Logistics has established a modern cold chain warehousing network covering five temperature zones, including ultra-low-temperature cold storage as low as -22°C. In such extreme environments, conventional electronic equipment experiences performance degradation, abnormal screen displays, or even complete failure due to low temperatures. Therefore, finding professional data collection mobile computers that can operate stably and efficiently in -22°C environments to support daily inbound, outbound, inventory management, and sorting operations became a key challenge for JD Cold Chain in improving overall operational efficiency.

Before introducing professional cold chain equipment, JD Cold Chain faced the following specific bottlenecks in daily operations in ultra-low-temperature environments:

• Complete failure of conventional equipment: Ordinary commercial mobile computers could not function properly in the extreme low temperature of -22°C, making mobile and digital data collection operations in this temperature zone impossible and heavily reliant on error-prone manual records.
• Low operational efficiency and accuracy: The lack of reliable mobile data collection tools made key processes such as receiving, inventory counting, and picking cumbersome, slow, and highly prone to human error, affecting inventory accuracy.
• High equipment maintenance costs: Non-professional equipment had extremely high failure rates in harsh environments, and frequent repairs and replacements brought high maintenance costs and operational interruption risks.

By deploying the AUTOID Q7-(Cold Chain) mobile computer specifically designed for cold chain, JD Cold Chain achieved significant operational value:

• Achieved end-to-end electronic processes and precise operations: Utilizing the device's stable scanning functionality in low temperatures, employees could accurately scan batch codes and location codes, realizing fully electronic operations from receiving, putaway, picking to outbound, significantly improving operational speed and accuracy.
• Ensures the outstanding reliability of equipment in extreme environments: The design of specialized cold chain equipment fundamentally reduces the failure rate in low-temperature, high-humidity environments. Consequently, the AUTOID Q7-(Cold Chain) has become the only brand in China to consecutively win the JD Logistics Cold Chain Equipment Centralized Procurement bid for five years (2020-2024), a testament to its reliability being validated over the long term.
• Optimized inventory management and storage utilization: Through precise data collection, dynamic binding and management of goods and locations within the cold storage were achieved, providing a data foundation for optimizing inventory layout and improving storage space utilization.

The solution adopted by JD Cold Chain is the SEUIC AUTOID Q7-(Cold Chain) mobile computer specifically designed for ultra-low-temperature environments:

• Customized low-temperature adaptability design: The core of this device lies in its low-temperature-optimized scanning head and heating function. This design effectively prevents the scanning lens from fogging or frosting in low-temperature, high-humidity environments, ensuring stable and clear barcode reading, fundamentally eliminating recognition errors and failures caused by the environment.
• Deep integration into the entire cold chain operation process: In the -22°C cold storage, employees can smoothly perform scanning operations for all work links while holding the AUTOID Q7-(Cold Chain) mobile computer. The stable operation of the equipment ensures the integrity of the data collection chain, enabling precise execution of Warehouse Management System (WMS) instructions and achieving efficient, seamless cold chain warehousing operations.
