摘要
在电气控制类课程的教学中,教师对学生接线情况的检查和考评是一件很繁琐的事,稍有不慎就会造成电气事故。电气控制线路接线故障诊断系统能够自动检查并提示学生接线所存在的问题,自动评分,具有禁止带故障合闸通电、保证训练过程的人身安全和设备安全的功能。由此组成的智能化电气控制实训室对提高技能训练和考评的效能有实际意义。
The checking and appraisal is a cockamamie thing for teachers in the class teaching on electrical control. The electrical control circuit wiring fault diagnosis system can automatically checking and prompting the existed wiring problems, and marking automatically. It is composed of MCS-51 single chip microcomputer, node switching matrix, decoding circuit, question number identification circuit, power supply controllers and voltage regulator. The electrical control circuit wiring fault diagnosis system and intelligent electrical control training room with accurate, fast and efficient performance, who increases teaching efficiency.
