简介：
Overview
This work proposes a flexible method for data communication between a film extrusion system and monitoring devices based on a message protocol called Message Queuing Telemetry Transport (MQTT). The protocol allows for the observation and recording of data from classical equipment through various devices over the internet.
Key Study Components
Area of Science
- Data communication
- Polymer processing
- Monitoring systems
Background
- MQTT is a publisher-subscriber protocol.
- It enables communication between multiple publishers and subscribers.
- Data can be published from legacy systems.
- Ambient temperature data can also be integrated into the system.
Purpose of Study
- To develop a flexible data communication structure.
- To facilitate real-time data monitoring.
- To enhance the capabilities of existing extrusion lines.
Methods Used
- Implementation of MQTT protocol.
- Data publishing from an existing extrusion line.
- Use of a broker device for data transmission.
- Integration of additional devices for temperature monitoring.
Main Results
- Successful data communication established between multiple devices.
- Real-time data from extrusion processes can be accessed remotely.
- Legacy equipment can be integrated into modern monitoring systems.
- Temperature data from different locations is effectively published.
Conclusions
- The MQTT protocol provides a robust solution for data communication.
- Flexibility in monitoring systems enhances operational efficiency.
- Integration of various data sources is achievable with this method.
What is MQTT?
MQTT is a lightweight messaging protocol for small sensors and mobile devices optimized for high-latency or unreliable networks.
How does the protocol enhance data communication?
It allows multiple devices to publish and subscribe to data streams, facilitating real-time monitoring and data collection.
Can legacy systems be integrated?
Yes, the protocol allows for data from legacy systems to be published and monitored alongside new devices.
What types of data can be monitored?
Both processing data from extrusion lines and ambient temperature data can be monitored using this system.
Is the system accessible remotely?
Yes, data can be accessed from anywhere on the internet, allowing for flexible monitoring.
What are the benefits of using a publisher-subscriber model?
It allows for efficient data distribution and reduces the need for direct connections between all devices.
