Multifunctional teaching aid for physical laboratory

Abstract

The invention discloses a multifunctional teaching aid for a physical laboratory. The multifunctional teaching aid for the physical laboratory comprises a current meter, a universal circuit board, a main computer, a power supply module, a protective circuit and a simulator, wherein the voltage meter and the ohmmeter are mounted at the right side of the current meter; an indicating lamp is mounted at the right side of the ohmmeter; a switch and an emergency stop button are arranged on the left side of the current meter; gear-shifting knobs are arranged below the current meter; an output power interface is fixed to the left side of the universal circuit board; the output end of the power supply module is electrically connected with the input end of a self-checking device; the output end of a filter is electrically connected with the input ends of the universal circuit board and the output power interface respectively; the output end of the output power interface is electrically connected with the input end of peripheral equipment; the output end of the peripheral equipment is electrically connected with the input end of the simulator. The multifunctional teaching aid for the physical laboratory modularizes various circuits in the form of an integrated circuit, so that the multifunctional teaching aid for the physical laboratory meets functional requirements of a variety of physical experiments, is complete in function and simplifies the experimental complexity.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a multifunctional teaching tool for a physics laboratory. Background technique [0002] At present, there is a lack of multi-functional teaching tools in junior high school physics laboratories. When teachers conduct electronic teaching in experimental classes, due to the complexity of the circuit, wiring on traditional lines is relatively cumbersome, and there is no simple circuit board. Instead, it is difficult for students to understand when they are studying. Teachers often need to change equipment constantly when teaching circuits with different functions, which is time-consuming and laborious. There is no unified storage place for wires, which is easy to cause loss of wires. Contents of the invention [0003] The purpose of the present invention is to provide a multi-functional teaching tool for physics laboratory to solve the problems raised in the above-menti...
