Example

[0053] First embodiment

[0054] This embodiment provides an embedded data acquisition system for the GDM network of the SIMATIC TDC system.

[0055] The SIMATIC TDC (hereinafter referred to as "TDC") system described in this embodiment is mainly applied to the 800-1000mm medium and wide hot rolling production line, for example, in the automatic control system of the 850 hot tandem rolling finishing mill. Take control.

[0056] The embedded data acquisition system used in the GDM network of the TDC system in this embodiment includes: raw data acquisition automatic control software FB_ACQ, storage module MEM_ACQ, single board computer, external memory, and data acquisition software TACQ; among them,

[0057] The raw data collection automatic control software FB_ACQ runs on the controller of the TDC system and is used to automatically complete the data collection operation according to the set period, and store the collected data in the storage module MEM_ACQ.

[0058] Preferably, the au...

[0072] Second embodiment

[0073] This embodiment provides an embedded data acquisition method for the GDM network of the SIMATIC TDC system, image 3 Shown here is a schematic flow chart 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] In step S201, a single board computer is inserted into the SIMATIC TDC rack as a data acquisition server.

[0075] An operating system runs in the single board computer. Preferably, the operating system is Windows or VxWorks. The performance of current single-board computers can already run the Windows operating system very well, and there is no problem of insufficient performance. Only the data acquisition software is run in the single-board computer system, and no other tasks are run to ensure that the system is not interfered by other tasks. .

[0076] Step S202: Load the original data collection automatic control softwa...

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...
