| description | The invention discloses a wind tunnel group data acquisition method and device based on isolation coupling. The method and the device aim at solving the problems that at present, existing monitoring systems are mainly used for local monitoring of single wind tunnel equipment, there are no public reports about cross-level data transmission and remote centralized monitoring schemes for wind tunnel groups, the existing monitoring systems are directly linked to wind tunnel measurement and control networks through a TCP/IP network, and there are corresponding technical risks. According to the acquisition method, on the basis of a three-layer framework including a coupling layer, a data layer and a monitoring layer, an independent data server is arranged for each wind tunnel and is in communication with a main PLC of the wind tunnel through a Profibus network, and wind tunnel state data is obtained from the main PLC of each wind tunnel; at the same time, a remote monitoring station is in communication with the data |
