Introduction to Cloud Monitoring
Cloud computing platforms provide computing, network, and storage capabilities, overcoming traditional data center limitations through virtualization, distributed computing, and grid computing. This advancement supports the rapid development of the Internet and IoT, similar to big data and AI, by offering balanced resources, rapid deployment, and high flexibility.
Core Functional Requirements
The system requires sending PLC gateway data to a cloud platform, establishing communication, binding the gateway to the platform, creating projects and devices, and mapping collection points for temperature and humidity. A key function is using an algorithm to judge equipment operational status based on these metrics, classifying conditions into normal (1), normal temp/abnormal humidity (2), abnormal temp/normal humidity (3), and abnormal temp/humidity (4). MQTT protocol is used for data push due to its lightweight and reliable nature.
System Design & Implementation
The system design follows four main steps: model creation, code writing, instance design, and system testing. This involves establishing an MQTT connection for data transfer, binding the cloud platform to the gateway (including project, device, and gateway settings), and configuring collection points for real-time monitoring of temperature and humidity. Device portraits are used to associate current PLC gateways with created projects and equipment, ensuring seamless data flow and analysis.
Algorithm for Status Detection
The core algorithm main(machineCode, wd, sd) processes temperature (x) and humidity (y) data. It categorizes temperature as normal (20-40°C) or abnormal, and humidity as normal (35-70%) or abnormal. Based on these categories, it assigns an output status (zp): 1 for normal operation, 2 for normal temperature with abnormal humidity, 3 for abnormal temperature with normal humidity, and 4 for both abnormal temperature and humidity. This provides a clear, real-time operational status for predictive maintenance.
