Modular Electric And Electronic Platform

As the basic hardware in the electric and electronic experiments, the equipment of the experiments is the key factor for the results. The traditional equipments can't meet with the current requirement, because of simple function and low integration. Therefore, the development of the facilities for the electric and electronic experiments becomes an imperative problem to be solved. Coupled with the modularization design, the thesis brings forward and finishes the design of the platform. The study provides solution for the electric and electronic experiment.Adopting the modularization design, the platform has a simple structure, convenient operation and easy expansion. And different modules can build up the various experiment circuits. Applying virtual instrument technology and making its software as corn, the platform achieves the digits and graphics for the measurement results. It reduces dependence on the traditional measurement instruments.First of all, according to the platform principles, the thesis confirms the important components and their relations. Then, thesis brings forward the whole schemes for the system and chooses the design tools.Secondly, in accordance with the scheme, the thesis discusses the development and design of the motherboard, function choice and control circuits and module circuits. Combined with the OrCAD PSpice Software, it also simulates the clock pulse circuits and relay circuits on the motherboard. The simulation results can satisfy the requirement of the circuit design. And the thesis takes an example to illustrate the design of the module circuits. Besides, it deals with the anti-interference and solutions for that in the process of the design.Eventually, the hardware is debugged in the thesis and platform is tested by experiments, the results of which are given in the thesis. The results can match with the simulation results, which shows the feasibility and rationality in the hardware design of the system. At the end of the thesis, the limitations and solutions of the platform are put forward and future works are expected.
