In industrial Internet of Things (IoT) scenarios, companies send real-time data from on-site sensors to cloud-based business systems. This data is used for real-time monitoring of the operating environment and device status, and for predictive maintenance. Alibaba Cloud IoT Platform uses the Message Queuing Telemetry Transport (MQTT) protocol to transmit data. This method supports a growing number of devices, meets real-time and stability requirements, and reduces operation and maintenance costs.
Solution design
The following figure shows the data link for the sensor data collection solution.
The data link is as follows:
- A sensor converts physical signals into digital information and formats the information as structured data. The data is then sent to Alibaba Cloud IoT Platform over a wireless network using the MQTT protocol.
- The IoT Platform rules engine filters, enriches, and transforms the raw data. It then sends the data to the business server in real time.
- The business server stores the data in a database and displays it to end users.
Procedure
- In the IoT Platform console, configure products, devices, topics, and data forwarding rules. For more information, see Cloud-side development.
- Develop the device-side application. For more information, see Device-side development.
- Develop the server-side application to accept device data and send control instructions. For more information, see Server-side development.
- Start the server-side program, connect to IoT Platform, and perform joint commissioning. For more information, see Joint commissioning.
