Multifunctional portable experiment device

Abstract

The invention discloses a multifunctional portable experiment device, which mainly solves the problem that laboratory equipment cannot be widely applied as the laboratory equipment is precious and has a large size. The multifunctional portable experiment device comprises a signal generation module, a signal collection module, a universal meter module, a power supply module, a microprocessor control circuit and a communication drive circuit, wherein the microprocessor control circuit is connected with the signal generation module for generating two output analog signals; the microprocessor control circuit is connected with the signal collection module for collecting two input analog signals; the microprocessor control circuit is connected with the universal meter module for storing and processing data collected by the universal meter; the communication drive circuit is connected with the microprocessor control circuit for uploading processed data which are stored in the microprocessor control circuit to an upper computer and carrying out bidirectional communication; and the power supply module is connected with other modules for outputting direct-current stabilized voltage. According to the multifunctional portable experiment device disclosed by the invention, basic functions of instruments such as a signal source, an oscilloscope, a direct-current stabilized power supply and a universal meter can be realized.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, in particular to a portable experimental device, which can be used for students' in-class experiments and extracurricular science and technology engineering innovation activity experiments.
