PLC Data Acquisition Gateway Solution for the Food Industry

The food processing industry is closely related to consumers' physical health and life safety, imposing strict requirements on the standardization, safety, and traceability of production processes. Currently, most food processing enterprises have achieved automated control over their production processes, with a large number of PLC devices being applied in various stages, including raw material sorting, cleaning, steaming, sterilization, and packaging.

However, many enterprises still face challenges in data acquisition and quality traceability: key parameters during the production process, such as temperature, time, pressure, and ingredient ratios, cannot be comprehensively and real-time acquired; data is stored locally on individual devices in a dispersed manner, lacking unified management and making it difficult to conduct end-to-end traceability; when quality issues arise in products, it is impossible to quickly locate the problematic stage, posing hidden dangers to food safety.

To meet food safety regulatory requirements, enhance enterprise quality management levels, and achieve full traceability of the production process, WideIOT offers an IoT solution based on PLC data acquisition gateways. By connecting to the PLCs of production line equipment, the gateway can acquire real-time operational status and industrial parameters of the equipment. It enables internet connectivity through 5G/4G/WIFI/Ethernet, allowing data to be interfaced with upper-level computers or cloud platforms. This facilitates functions such as remote monitoring, fault alerts, remote control, and data analysis, aiding in the realization of refined and intelligent production management.

Managers can use the platform to monitor the operational status of the entire production process in real-time, view real-time data and trends of various process parameters, and promptly identify anomalies during production. For example, when the sterilization temperature fails to reach the set standard or the sterilization time is insufficient, the platform immediately issues alert notifications (via WeChat, SMS, email, etc.), enabling managers to take timely adjustment measures and prevent the production of non-conforming products.

Furthermore, to assist enterprises in meeting food safety regulatory requirements, various important production data can be automatically generated into reports and exported for storage at any time, providing complete and authentic evidence for regulatory inspections and helping enterprises smoothly pass compliance audits. Meanwhile, enterprises can optimize their production processes by analyzing production data from different batches of products, identifying key factors affecting product quality, adjusting process parameters, and enhancing the stability and consistency of product quality.
