Problems solved by technology

Therefore, even if the prices of solutions from foreign manufacturers are high, domestic factories and control system integrators in demand have to adopt solutions from foreign manufacturers
[0006] At the same time, since Siemens' GDM network data cannot be collected directly, it must be programmed and configured in the TDC controller, and then the data is collected through Ethernet. and system performance tuning requirements

[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 ...

Abstract

The invention provides an embedded data acquisition system and method for GDM networks of SIMATIC TDC systems, and aims at solving the problem that the data acquisition of TDC systems in the prior artmust be realized through GDM network cards. The system comprises automatic control software FB-ACQ, a memory module MEM-ACQ, a single board computer and data acquisition software TACQ. The FB-ACQ isoperated on a TDC system controller, completes data acquisition for the TDC system controller according a period configured for the acquisition and stores the acquired data in a specific area MEM-ACQof a GDM; and the single board computer is inserted into a TDC system rack in an embedded manner, and completes the acquisition of real-time data and historical data through operating the TACQ. The embedded data acquisition system and method are capable of realizing the high-speed acquisition of GDM data of the TDC systems, ensuring the time precision of data acquisition, and ensuring that the cumulative time error of every 10000 sample values does not exceed 1 ms; and the fastest sampling period can reach 1 ms, up to 50 pieces TDC controller data can be acquired at the same time, and up to 2048 channels can be acquired at the same time.

Description

technical field [0001] The invention belongs to the technical field of computer and automatic control, and in particular relates to an embedded data acquisition system and method for the SIMATIC TDC system GDM network. Background technique [0002] SIMATIC TDC (Technology and Drive Control) (hereinafter referred to as "TDC") is a product used for process and drive control in Siemens' automation series products. It is a modular multi-processor system. The products developed after D are also the controller products with the most advanced technology and the most powerful functions launched by German Siemens. A SIMATIC TDC consists of one or more racks. The rack is equipped with CPU, I / O modules and communication modules, and various required modules can be inserted into the rack as required. SIMATIC TDC is especially used in process control, fast response and multi-drive synchronization in large equipment, solving complex drive, control and technical tasks on a single platfor...
