WideIOT provides a remote operation and maintenance (O&M) solution for food processing machinery. Via industrial intelligent gateways, it connects to the control systems of food processing machinery to collect data such as equipment operation parameters (e.g., temperature, pressure) and hygiene indicators (e.g., cleanliness). The data is transmitted to a remote O&M platform through secure networks, where real-time analysis is conducted to monitor the equipment’s operation status and hygiene conditions. When equipment malfunctions or hygiene indicators turn abnormal, O&M personnel are promptly notified to address the issues. Additionally, the solution supports remote O&M operations to ensure the stable running of the machinery.
