Cold storage facilities play a crucial role in the cold chain logistics system, significantly impacting the quality and safety of products in industries such as food, pharmaceuticals, and chemicals.

As market demand continues to grow, the scale and number of cold storage facilities are rapidly expanding. However, traditional cold storage management methods suffer from issues such as low informatization levels, lack of real-time monitoring tools, and delayed responses to equipment failures, leading to compromised product quality and increased operational costs. Therefore, establishing an IoT-based monitoring and operation & maintenance management system for cold storage facilities has become particularly urgent.

System Architecture

This solution adopts an IoT hierarchical architecture consisting of the "perception layer, transport layer, platform layer, and application layer," with WideIOT industrial intelligent gateways at its core to enable real-time monitoring of cold storage environments, data transmission, intelligent analysis, and operation & maintenance management.

• Perception Layer: Deploy temperature and humidity sensors, equipment controllers (PLCs), etc., to monitor and control environmental parameters and equipment status within the cold storage.

• Transport Layer: Utilize wireless communication technologies such as 5G/4G, Wi-Fi, and Ethernet to transmit real-time data from the perception layer to the platform layer.

• Platform Layer: Build a data processing and analysis platform based on cloud computing and edge computing technologies to achieve data storage, processing, and visual display.

• Application Layer: Provide functions such as remote monitoring, abnormal alerts, operation & maintenance management, equipment management, and data analysis to meet diverse management needs of enterprises.

Core Equipment

The industrial intelligent gateway, as the key equipment connecting the perception layer and the platform layer, offers the following features:

• Multi-protocol Support: Supports various communication protocols such as Modbus, RS485, and Ethernet, enabling flexible connection to various sensors and devices.

• High Reliability: Adopts an industrial-grade design with an IP30 protection rating and a full-metal casing to adapt to the complex environment of cold storage.

• Low Power Consumption: Supports low-power mode to extend device battery life and reduce maintenance costs.

• Flexible Deployment: Supports multiple internet access methods such as 5G/4G/Wi-Fi/Ethernet, facilitating rapid setup of the IoT system.

• Edge Computing Capability: Incorporates an edge computing module for local data processing and filtering, reducing the load on the cloud.

  

System Functions

Remote Monitoring

By logging into the management platform via mobile phones or computers, managers can view in real-time the location distribution, operational status, working parameters (such as temperature, humidity, voltage, and current), and video surveillance footage of cold storage facilities. This enables managers to stay informed about cold storage dynamics anytime and anywhere, ensuring product safety.

Abnormal Alerts

Set intelligent alert rules. When abnormal conditions such as temperature and humidity exceeding standards or equipment failures are detected, the system automatically notifies relevant personnel via WeChat, SMS, email, etc. Alert information includes the faulty equipment, occurrence time, and fault type, facilitating quick location and response.

Operation & Maintenance Management

When equipment fails, the system automatically generates maintenance work orders and assigns them to responsible personnel. Managers can query and track work order progress, processing time, work logs, and other information, intervening and adjusting as necessary to ensure normal equipment operation. Additionally, the system supports remote programming debugging and program uploading/downloading, improving maintenance efficiency.

Equipment Management

Unified management of cold storage equipment connected to the platform, including information such as equipment quantity, type, purchase time, failure frequency, and maintenance records. When equipment information changes, it can be quickly edited and modified, achieving transparent management.

Video Surveillance

Deploy high-definition cameras to enable real-time video surveillance of the interior of cold storage facilities. Managers can remotely view work behaviors within the cold storage, standardize operational procedures, and provide an efficient and reliable means for online inspections.

Data Analysis and Optimization

Analyze cold storage operational data through multiple visual data charts to assess equipment performance and fault risks. Based on the analysis results, help enterprises optimize cold storage layout, improve ventilation conditions, adjust equipment operating parameters, and achieve efficient operation & maintenance and cost reduction.
