Industrial network information acquisition device, method, monitoring system and storage medium

Abstract

The embodiment of the invention discloses an industrial network information acquisition device, a monitoring system and a method. The industrial network includes: the layer to be tested and the control layer; the control layer includes a plurality of software PLCs. The industrial network information acquisition device includes: a data transparent transmission and acquisition module, which is used to establish a one-to-one corresponding transmission channel between a plurality of software PLCs and a plurality of equipment groups of the layer to be tested, and through the transmission channel, the device from the layer to be tested The data message of the group is directly transparently transmitted to the corresponding software PLC, and the data message from the software PLC is directly transparently transmitted to the corresponding device group of the layer under test; and while transparently transmitting the data message, according to the preset The data acquisition and processing rule is to obtain the corresponding data from the data message, and output the obtained data after corresponding processing; and the information gateway module is used to receive the data from the data transparent transmission and acquisition module. It can be seen that the technical solution of the present invention can realize the data collection of the equipment group of the layer to be measured.

Description

technical field [0001] The invention relates to the field of industrial networks, in particular to an industrial network information acquisition device, method, monitoring system and storage medium. Background technique [0002] Industrial communication networks used in industrial automation and process automation are usually designed in a layered structure. figure 1 An industrial network architecture in application is shown in . Such as figure 1 As shown, the industrial network includes four levels: field level 1, control level 2, operation level 3 and management level 4. Of course, some industrial networks can also have other layering methods, for example, including the field layer and the control layer; for example, including the field layer, control layer and network layer; or, including the field layer, control layer and monitoring layer, etc. . [0003] Among them, the field layer mainly refers to the device group layer under the network layer of equipment that per...

AI Technical Summary

Problems solved by technology

PLC does not bridge and route between the control layer network and the field layer network, which is very good for the security and robustness of data control, but at the same time it is difficult to monitor and diagnose the field layer device group in real time
