Physical electricity experiment operation circuit connection automatic evaluation method

Abstract

The invention relates to the field of automatic evaluation of experimental operation, in particular to an automatic evaluation method for connection of a physical electricity experimental operation circuit, which comprises the following steps of: determining a physical electricity experiment to be automatically evaluated and all related experimental apparatuses and experimental apparatus connecting wires thereof, and establishing a standardized experimental apparatus connecting circuit diagram; the method comprises the following steps: representing experimental apparatuses of a physical electricity experiment to be automatically evaluated as branches, representing connecting wires of the experimental apparatuses as nodes, and mapping a circuit diagram of the physical electricity experiment to be automatically evaluated as a circuit geometric diagram formed by the branches and the nodes; whether the experimental apparatus of the experimenter is connected to the circuit or not is judged according to the spatial positions of the experimental apparatus binding post and the experimental apparatus connecting wire clamping head of the experimenter.

Description

technical field [0001] The invention relates to the field of automatic evaluation of experimental operation, in particular to an automatic evaluation method of circuit connection of physical and electrical experimental operation. Background technique [0002] Carrying out students' experimental operation examination and strengthening students' practical operation are the requirements of students' quality education in the process of education and teaching reform. The test of students' experimental operation skills requires quantitative measurement and evaluation of students' experimental behavior. The premise of quantitative measurement and evaluation is to be able to correctly judge whether the students' experimental operation is correct. [0003] Judging based on operation steps can reflect students' experimental skills, but due to the large number of students, the implementation of traditional manual judgment methods is relatively expensive. The automatic evaluation metho...

Problems solved by technology

The important operation that embodies students' experimental skills in the physical electricity experiment operation is to connect the circuit correctly. In the automatic evaluation, judging whether the circuit is connected can judge whether the circuit is connected correctly by judging the connection status of the wire and the experimental equipment. However, in the actual circuit connection process, the wire connection is due to Crossover, irregular placement, no order, etc., it is difficult to accurately identify the connection status of each wire by using deep learning methods, so it is difficult to automatically judge whether the experimental circuit is connected correctly through the connection status of the wires and experimental equipment
