Problems solved by technology
[0003] Due to its characteristics, DCS is generally closed and less open to the outside world. However, with the development of industrial Internet of Things technology, people need to collect more industrial production data to improve the production efficiency and production supervision of the process industry.
In the existing technology, DCS real-time data is mainly provided externally through OPC (OLE for Process Control) software, but because the operating system environment that OPC software relies on may have potential security holes, there is a risk of leakage during data transmission

The present invention provides a monitoring data transmission method and device for a distributed control system. The method includes: when receiving a device operation data packet, determining the data protocol information of the device operation data packet; judging according to the data protocol information Whether the equipment operation data packet satisfies the preset transmission condition; if the equipment operation data packet meets the transmission condition, each original data in the data area of the equipment operation data packet is mapped according to the preset mapping rule , to obtain monitoring data corresponding to each of the original data; generate a monitoring data message according to each of the monitoring data; and send the monitoring data message to a preset cloud server. Compared with the traditional way of providing externally through OPC software, it can effectively avoid the risk of data leakage caused by potential security holes in the operating system environment on which OPC software depends and the opening of high-risk ports, thereby ensuring data security.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a monitoring data transmission method and device for a distributed control system. Background technique [0002] With the development of automation control technology, many large enterprises usually adopt a control system integrating management and control. Among them, the most widely used is the distributed control system (Distributed Control System, DCS). The distributed control system is based on the microprocessor Based on this, it is a new generation of instrument control system that adopts the design principles of decentralized control functions, centralized display operations, taking into account the design principles of division and autonomy and comprehensive coordination. [0003] Due to its characteristics, DCS is generally closed and less open to the outside world. However, with the development of industrial Internet of Things technology, people need to collect...
