An automatic scoring system and method applied to a chemical unit training device

Abstract

The invention discloses an automatic scoring system and method applied to a chemical engineering unit practical training device. The system comprises an operation step detection module, an operation quality monitoring module, an operation quality checking and evaluating module and a scoring module; the operation step detection module is configured to detect operation steps of which the sequentialorder is required; the operation quality monitoring module is configured to detect whether or not the operation quality of operation personnel meets the technological condition in the operation process and detect whether or not the operation process meeting the technological condition is reasonable; the operation quality checking and evaluating module is configured to judge the standard of steps,the quality of technological adjustment quality, the stability of parameter regulation of electrical instruments and the operation duration in the operation process of the operating personnel according to the detection result of the operation step detection module and the operation quality monitoring module; the scoring module is configured to sequentially score all steps in the operation processon the basis of the checking and evaluating criterion of each chemical engineering unit and in accordance with the judgement result of the operation quality checking and evaluating module, and the score gaining and deducting situation in the operation process is summarized and analyzed.

Description

technical field [0001] The disclosure relates to the field of chemical unit operation training, in particular to an automatic scoring system and method applied to a chemical unit training device, especially suitable for the operation evaluation and daily training of the chemical unit operation training device controlled by DCS. Background technique [0002] In addition to basic training on safety, fire protection, laws and regulations, new employees of chemical companies should have a basic understanding of the process flow of chemical operation positions before taking up their jobs, and master basic operating skills in order to adapt to and meet the needs of production and operation positions; on-the-job employees must regularly Only by upgrading skills can we meet the needs of enterprises with increasing automation and ensure the safe and stable operation of production. [0003] During the daily skills training, skills appraisal and competition of operators, five sets of c...

AI Technical Summary

Problems solved by technology

[0003] During the daily skill training, skill appraisal and competition of operators, five sets of chemical unit operations including rectification, evaporation, absorption and desorption, heat transfer, and fluid transportation are the main training and assessment items, and the assessors will evaluate the employees according to the assessment standards. On-site scoring has the following main problems at this stage: (1) During the daily training and learning process, the standardization of the operation steps and the rationality of the operation process cannot be reflected, and the real operation level of the employees cannot be intuitively reflected; (2) Skill appraisal and competition During the assessment, the examiners need to score items one by one according to the scoring standards, which is labor-intensive; (3) The examiners have different understandings of the assessment standards, the technical level of the assessment is not uniform, and there are some subjective factors that affect the scoring
