Problems solved by technology

[0003] The hydraulic controllers imported in the early 1990s were expensive and had limited functions, making it difficult to perform secondary processing on the analysis results and not universal
Moreover, in the experiment, the motion control part of the system is usually separated from the data acquisition part, which brings great inconvenience to the experiment.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with drawings and embodiments.

[0015] Such as figure 1 , the control system uses NI's modular hardware PCI-6259 as the system's input and output cards. The analog input part is composed of PCI-6259 board, cable and terminal board. The board has 32 channels of 16-bit inputs with a total speed of 1.25MS / s sampling rate. It can fully meet the requirements of the system's 8-channel 12-bit precision and sampling rate of 4096S / s. The card has 4-channel 2.8MS / s sampling rate synchronous output, 16-bit precision, and can also meet the requirements of the system 4-channel 12-bit precision and sampling rate 4096S / s. Using this board can be completed with one board. Input and output functions. And all operations can be carried out through DMA, reducing CPU usage while ensuring smooth analog input and output without losing points, and fulfilling the system's real-time requirements. The input ranges are plus...

Abstract

The invention relates to a hydraulic controller auxiliary control system. An industrial control computer outputs four paths of simulated seismic wave signals and at most 12 paths of synchronous digital signals through an input-output card PCI-6259, and a hydraulic controller drives a hydraulic vibration rod to vibrate in dependence on the four paths of seismic waveforms. The hardware configuration of the hydraulic controller auxiliary control system is selected, a software system of the hydraulic controller auxiliary control system is compiled by means of a Labview platform, exploitation of the source program is greatly simplified, synchronic output of a plurality of digital and simulation channels and a multi-sensor synchronous acquisition function are achieved, multichannel digital and simulation outputs and multi-sensor information are displayed on the same interface, the man-machine interaction interface is visual and friendly, and during a practical test, a satisfied test effect can be achieved.

Description

[0001] Technical field [0002] The invention relates to an auxiliary control system of a hydraulic controller, which is suitable for the mechanical field. Background technique [0003] The imported hydraulic controllers in the early 1990s were expensive and had limited functions, which made it difficult to perform secondary processing on the analysis results and were not universal. And in the experiment, the motion control part of the system is usually separated from the data acquisition part, which brings great inconvenience to the experiment. But its mechanical part works well, we only need to modify its auxiliary control system to improve these deficiencies, prolong its service life and save test costs. Contents of the invention [0004] The present invention proposes a hydraulic controller auxiliary control system. The system selects the hardware configuration of the hydraulic controller auxiliary control system, and uses the Labview platform to write the software syst...
