Components and functions of each module of the portable experimental circuit board are discrete, the stability is high, circuits of each module can be used independently, the circuit setting of each module only needs to be known according to an experiment instruction during use, the understanding of the circuits is increased, and components in all the models can be freely combined and repeatedly used according to needs, so as to carry out secondary development.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, in particular to a portable experimental circuit board. Background technique [0002] The circuit experiment course is an important practical course in the training program of electrical majors. At present, the circuit experiment course is mainly realized in three forms based on discrete devices, based on general experimental benches or based on virtual instruments. [0003] The experimental form based on discrete devices is conducive to helping students establish an intuitive understanding of various components and measuring equipment, but it is large in size and low in integration, making it difficult to open new experiments. Based on the experimental form of the general experimental platform, its components and measuring equipment are highly integrated, but most of the components are located on the back of the panel or in the experiment box, which is not easy to observe, which weak...

[0003] The experimental form based on discrete devices is beneficial to help students establish an intuitive understanding of various components and measurement equipment, but it is large in size and low in integration, and it is not easy to open new experiments

Based on the experimental form of the general experimental platform, its components and measuring equipment are highly integrated, but most of the components are located on the back of the panel or in the experiment box, which is not easy to observe, which weakens students' intuitive understanding of various components and measuring equipment

Moreover, the experimental forms based on discrete devices and general-purpose test benches need to be completed in the laboratory, and the teaching flexibility is relatively poor, which is not conducive to portability, and is inconvenient for teachers to demonstrate in the classroom.

The experimental form based on virtual instruments has greatly improved in terms of integration and experimental flexibility, is not limited by experimental occasions, and is easy to develop new experiments, but the existing experiments based on virtual instruments are mainly through breadboards and virtual systems. To achieve, the components need to be installed on the breadboard one by one when using it, resulting in more components to be configured, and the components are scattered, making it difficult to carry and store
