Abstract

The invention discloses an automatic detection method and an automatic detection device for a connection wire of an electrical experimental facility. The automatic detection device for the connection wire of the electrical experimental facility comprises a (Micro Processing Unit) MCU, an 8155 chip, 24 relays, 24 free-wheeling diodes, 24 triodes, 48 connection terminals, 24 current-limiting resistors, 24 pull-up resistors, a communication module, an alarming module and a keyboard module. The automatic detection device for the connection wire of the electrical experimental facility adopts the triodes to drive the relays, so that the circuit is simple in structure, the elements are less, the cost is low, the connection status among the terminals of the experimental facility can be automatically detected, the elements are protected effectively, and the reliability is high; the intelligent detection device is adopted, so that the workload of experiment advisors can be effectively reduced; once the detection device emits alarm information, students can find problems by themselves, so that the problem-solving ability of the students is effectively improved, and the quality of teaching is ensured. The automatic detection method and the automatic detection device for the connection wire of the electrical experimental facility are applicable to all electrical experimental facilities for teaching.

Description

technical field [0001] The invention relates to an automatic detection method and device for connecting wires of electrical experimental equipment, in particular to an MCU-based, intelligent device for automatically judging whether the wiring is correct or not, and belongs to the field of electrical engineering. Background technique [0002] Experiments are an important method of studying natural sciences. Electrical experiments are especially important in undergraduate teaching. In addition to further consolidating theoretical knowledge, they can also train students to master experimental skills and lay a solid foundation for future engineering and technical work. The first step to complete electrical experiments is the wiring between circuits. During the experimental teaching process, it often occurs that circuits or components are burned due to students' wiring errors, resulting in property losses and even accidents. [0003] In the existing experimental teaching, the stu...
