Magnetic memory fixed-point sound and light alarm control method capable of customizing errors

Abstract

The invention discloses a magnetic memory fixed-point sound and light alarm control method capable of customizing errors, and belongs to the technical field of fixed-point flaw detection and monitoring of metal materials. The novel magnetic memory fixed-point sound and light alarm control method can facilitate real-time monitoring of metal materials. The method comprises a system calling and dataprocessing main program, a data collection subroutine, an error value customizable filter processing subroutine and a threshold value acquisition subroutine for stopping the service program. The system calling and data processing main program utilizes an assembly pseudo instruction to set LINEADR1 as a threshold value storage address, ADTURN1 as an acquired data storage zone first address, ADTURN2as a temporary computed data storage area first address, LINEADR0 as a filtering data storage address and LINEADR2 as an error value storage address.

Description

technical field [0001] The invention belongs to the technical field of fixed-point flaw detection monitoring and detection of metal materials, and in particular relates to a magnetic memory fixed-point acousto-optic alarm control method with self-defined errors. Background technique [0002] With the development of modern productivity, metals have been applied to various fields of our lives, but the economic losses caused by metal damage are also increasing year by year. However, the general non-destructive testing technology can only detect the cracks or defects that have been formed, but cannot detect the fatigue damage caused by stress concentration in an early stage. The principle of metal magnetic memory is that ferromagnetic materials form magnetic and elastic interaction energy under the action of stress, which reorients the magnetization, which leads to changes in the magnetic field strength to achieve the purpose of measurement, so early detection of metal materials...

Problems solved by technology

However, traditional metal magnetic memory detectors are all mobile scanning devices, which cannot monitor fixed-point metals in real time for a long time

Moreover, the filter system of the traditional metal magnetic memory detector has the characteristics of relatively large equipment volume or because of the large amount of programs, due to the complex algorithm, it is not conducive to the implementation of hardware or software.
