[0073] The present embodiment provides a kind of embedded data acquisition method for SIMATIC TDC system GDM network, image 3 Shown is a schematic flowchart of the embedded data collection method for the GDM network of the TDC system in this embodiment. Such as image 3 As shown, the method includes the following steps:
[0074] Step S201, inserting a single-board computer into a SIMATIC TDC rack as a data collection server.
[0075] An operating system runs in the single-board computer. Preferably, the operating system is Windows or VxWorks. The performance of the current single-board computer can already run the Windows operating system very well, and there will be no problem of insufficient performance. In the single-board computer system, only the data acquisition software is run, and other tasks are no longer run, so as to ensure that the system is not interfered by other tasks. .
[0076] Step S202, loading the original data acquisition automatic control software ...
