Software section comprises the parameter setting program, carries out test procedure and carries out browse operation program three parts composition.
The major parameter of parameter setting program setting is: sample composition, test duration, content measurement, sample pre-arcing characterisitics temperature, sample burn-off rate are measured, the picture storing mode, sample pre-arcing characterisitics temperature: comprise beginning temperature of fusion, hemisphere point temperature, the temperature of trickling, respective heights is provided with etc.;
Carrying out test procedure mainly finishes: sample fusion process image, the height of judgement sample, test sample pre-arcing characterisitics temperature and height, the image of storage test process and temperature etc.;
Carrying out the browse operation program mainly finishes: browse whole test processs, can artificially revise test result, the printout test result can be deleted the useless test result of storage etc.
Software section is finished above-mentioned functions on the WIN98 platform.
The difference of the utility model and classic method is: 1, adopted the video imaging technology to replace traditional optical imaging method; 2, adopt computer picture to gather automatically and image recognition technology, replace the artificial observation method, have the raising automaticity, save the working time, save remarkable advantages such as manpower.
The utility model also has following characteristics: 1, the present invention adopts the judgement of video imaging, the processing of computing machine automated graphics and sample temperature of fusion characteristic, can quote beginning temperature of fusion, hemisphere point temperature, trickling temperature, and temperature of fusion, eliminated the influence of human factor to test result.2, can carry out the playback of image and data and browse the whole test processs of sample.3, the image of test result and data are selected high-resolution video imaging and image processing techniques for use, make the fusion process picture more clear, can store all images of each sample fusion process, have significantly improved measuring accuracy.
