Application Scenario Practice

We will take power consumption monitoring, air compressors and transformers commonly used in factories as examples, and transmit device information to the EMQ platform in real time through the gateway protocol, demonstrating how the joint solution of EMQ and Mingdao Cloud IIoT can realize industrial IoT device management.

In this case scenario, our storage database uses the MySQL database, which can be seamlessly connected with Mingdao Cloud Platform.

Industrial protocol analysis

Neuron was born for the "connection" of the Industrial Internet of Things. It supports one-stop access and MQTT protocol conversion for multiple devices with different communication protocols and dozens of industrial protocols at the same time. It only takes up ultra-low resources and can be native or containerized. Deployed in various edge hardware of X86, ARM and other architectures to help build industrial IoT applications. After the integration of Neuron and EMQX, various industrial equipment can be connected and distributed to other industrial information systems.

message rule engine

EMQX processes the Modbus protocol data collected by Neuron through the message engine. Based on this, EMQX realizes data cleaning and data routing on the near-edge side, so that Mingdao Cloud applications can directly obtain valuable data for business. This practice uses MySQL as the database required for customer data storage, correctly forwards alarm data and normal IoT message data to the pre-built database, and waits for the data form on the Mingdao Cloud side to pull data and call business applications .

data integration

The core capability of Mingdao Cloud data integration is to solve the problem of data dispersion in various business systems. It achieves real-time data synchronization by directly connecting to the database. Users only need to configure simple field mapping rules to realize the synchronization of databases and worksheets, and also support data synchronization between databases.

Configure database integration information through the data integration function of Mingdao Cloud Integration Center. Currently, the supported external database types include: MySQL, MariaDB, SQL Server, IBM db2, and PostgreSQL. Will continue to add other common databases, such as MongoDB, Oracle, etc.:

The equipment operation information is transmitted to Mingdao Cloud through the synchronization task of Mingdao Cloud Integration Center:

Equipment operation information data is transmitted to Mingdao Cloud in real time:

Equipment file management

Using the worksheet component of Mingdao Cloud, you can build a device information table, record the basic information of the device, supplier, operating data, etc. in custom field information, and manage the basic information and operating status of the device:

Device information gallery map:

Device information status dashboard:

equipment monitoring

Using smart IoT devices, device data can be collected, and the data can be uploaded to Mingdao Cloud through the EMQ IIoT data integration platform to realize remote monitoring of devices. In Mingdao Cloud, by building a visualized dashboard or report, the device data can be intuitively displayed, so as to monitor the device in real time.

The device runs the dashboard, and the alarm information is clear at a glance:

Device abnormality information:

equipment maintenance

The operation of equipment requires continuous maintenance and maintenance. In order to better manage and maintain factory equipment, Mingdao Cloud provides work order and task management functions. By submitting work orders and tasks, the maintenance and maintenance of equipment can be realized, and the problems that arise during the use of equipment can be checked and solved in a timely manner. It is possible to manually discover equipment failures and submit a work order, or to automatically trigger the generation of a maintenance work order by pushing the equipment operation information through the EMQ IIoT data integration platform.

Work order progress management:

Device alarm triggers a work order

If the equipment fails or is abnormal, it is necessary to send an alarm notification in time. Alarm rules can be set in Mingdao Cloud, and notifications can be made through WeChat, email, etc. to ensure that equipment problems are resolved in a timely manner.

The alarm message triggers the work order system composed of workflows at the same time, and a maintenance work order is generated at the same time as the alarm. Combining SMS, email and other alarm capabilities to ensure that maintenance work can be carried out to maintenance personnel, reducing business losses caused by failures.
