Abstract
With the development of data monitoring system for industrial equipment, the convenience of data monitoring is paid more and more attention. Traditional data monitoring mostly uses specialized software or visual interface on the device to achieve the purpose of monitoring data, the workflow will be more complex. Even if there is a unified device to receive the data, it is not realistic to monitor all the time. In addition, for the load problem of the micro device, mounting the OPC UA client by itself is heavy. Therefore, in order to improve the visibility of field device data, reduce the load of micro devices and simplify the complex workflow, this paper studies the cross-platform device monitoring system based on OPC UA. The local OPC UA server is used to collect data from industrial devices, and the collected data is processed and transferred to the cloud storage system. The stateless RESTful HTTP request style simplifies the complexity of implementing data transfer between a generic client (browser or other HTTP client) and a Web server, and truly enables users to monitor data anytime and anywhere without consuming too many resources.
