Description
Technical field
The present invention relates to defect in rope detection technique field, specifically a kind of defect in rope detecting system based on DSP.
Background technology
Steel wire rope has a wide range of applications in many industrial circles, and therefore its safety problem is always everybody problem of interest.The system being applied to defect in rope detection at present has that volume is big, high cost, precision are low, poor reliability the shortcomings of, therefore developing efficient, reliable, portable defect in rope detecting system is the task of top priority.
Content of the invention
In order to overcome the shortcoming of upper described prior art, the invention provides a kind of defect in rope detecting system based on DSP, can defect in rope signal being acquired and analyzes, thus being estimated to steel wire rope safety in utilization of convenience and high-efficiency.
The present invention is to be realized with following technical scheme：A kind of defect in rope detecting system based on DSP, including for carrying out magnetized magnetizing assembly, signal pickup assembly and the DSP signal processor for data processing for gathering magnetic leakage signal to steel wire rope；Described signal pickup assembly adopts multiple Hall elements, and multiple Hall elements are arranged according to matrix and constituted a circle detection circle, and steel wire rope passes through from circle detection circle；Described magnetizing assembly includes two excitation mechanisms, the symmetrical upper and lower being arranged on circle detection circle of two excitation mechanisms；The signal processing is delivered to PC by data collecting card by DSP signal processor.
The invention has the beneficial effects as follows：Structure is simple, convenient disassembly, can easily and effectively defect in rope signal be acquired processing, thus being estimated to steel wire rope safety in utilization；Equipment cost is relatively low, and detection limitation is little, is applicable to the working environment of complexity.
Brief description
Fig. 1 is present configuration schematic diagram；
Fig. 2 is principle of the invention block diagram.
In figure：1st, excitation mechanism, 11, permanent magnet, 12, soft magnetic bodies, 2, Hall element.
Specific embodiment
As shown in figure 1, a kind of have one for steel wire rope is carried out with magnetized magnetizing assembly, signal pickup assembly and the DSP signal processor for data processing for gathering magnetic leakage signal based on the defect in rope detecting system of DSP；Described signal pickup assembly adopts multiple Hall elements 2, and multiple Hall elements are arranged according to matrix and constituted a circle detection circle, and steel wire rope passes through from circle detection circle；Described magnetizing assembly includes two excitation mechanisms 1, the symmetrical upper and lower being arranged on circle detection circle of two excitation mechanisms 1；The signal processing is delivered to PC by data collecting card by DSP signal processor.
As shown in figure 1, described excitation mechanism 1 is by soft magnetic bodies 12, and it is arranged on the permanent magnet 11 at soft magnetic bodies two ends and constitutes, two permanent magnets correspond to N pole and the S pole of permanent magnet.Permanent magnet is used for steel wire rope is magnetized, and soft magnetic bodies are mainly used in changing the direction of the magnetic line of force, make the magnetic resistance of whole magnetic loop reach minimum.
Hall element adopts high-precision linear Hall element, and high-precision linear Hall element enters row matrix arrangement composition, establishes spatial triaxial Measurement Method for Magnetic Field it can be deduced that the stray field at steel rope fault is in axial direction, radial direction and circumferentially distributed vector correlation.
Operator only need to penetrate detecting system steel wire rope and can complete the collection to defect in rope signal and process, connecting computer can use software analysis to go out steel rope fault situation, operation principle is as shown in Fig. 2 whole detection and analysis process includes being that the signal that the magnetization of steel wire rope, the signals collecting of Hall element, DSP signal processor collect to Hall element carries out processing, data collecting card gathers the signal that DSP signal processor processes cross and sends into the analysis collecting signal to measurement object.
Work process：Steel wire rope position shown in Fig. 1 passes through, and when steel wire rope occurs fracture of wire, the magnetic signal at fracture of wire occurs clear signal；Hall element exports the magnetic leakage signal at this to DSP signal processor processes, and the signal after processing is delivered to PC by data collecting card by DSP signal processor, and PC is analyzed to data processing, thus being estimated to steel wire rope safety in utilization.
