In recent years,with the advancement of MEMS technology,the equipment needed in production is developing towards miniaturization and miniaturization.In some occasions,MEMS micro-energy supply is needed,which gives a good development of MEMS micro-energy system.However,the current micro-energy testing methods still lie in the stage of manual detection using an oscilloscope,a digital voltmeter,etc.,and there are disadvantages such as cumbersome testing process,low test accuracy,frequent manual operation and calculation.Besides,at present,due to the lack of a unified testing system,different testing scenarios and testing platforms need to be built for different types of micro-energy test targets which are cumbersome.Therefore,research on micro-energy testing systems is of great significance for the development of micro-energy technologies and the entire MEMS industry.In this paper,the design of micro-energy testing system is carried out for the development of MEMS micro-energy related test systems.A scheme designed based on ARM9 embedded micro-energy testing system is proposed,and the design about Linux embedded system structure is completed.The ARM9 embedded core board is used as the main controller and processor and the peripheral hardware circuit such as reset module,power supply module,communication module,as well as multi-channel micro-energy input interface circuit and relay array control circuit are designed independently,performing human-computer interaction by display terminal as well;on software,the graphical interface and testing program of the micro-energy testing system are designed and written,which has the advantages of simple operation,friendly interface,accurate measurement and rapidity.The module debugging,hardware machine debugging,and the output test of the micro-energy testing system are carried out.The micro-energy testing system was tested experimentally where the micro-energy collectors and micro-energy systems were used as test objects and used to simulate the working mode of the intelligent fuse system.The experimental results show that testing system works reliably and can quickly and accurately test micro-energy output parameters,which meets the need of actual measurement method.The main work done by the thesis is:(1)Based on the review of relevant literature,the research results as well as shortcomings of micro-energy testing methods by universities and research institutes at home and abroad were analyzed.An automatic test scheme was proposed to solve the shortcomings like low automation and low measurement accuracy in the existing testing methods.(2)According to the micro-energy testing proposal,the design of each functional module and hardware circuit of the micro-energy testing system was completed,and the system integration and the design of the printed circuit board were carried out.(3)Based on the Linux architecture,this paper builds an embedded software system platform,writes related character drivers and upper-level applications,and completes the modular design of relay control,data acquisition and graphical interface.The design of the main interface,test interface,result interface and setting interface is completed.(4)The welding and debugging work of each module of the micro energy testing system was completed,and relevant test experiments were carried out for the micro-energy collectors and micro-energy systems such as wind energy and solar energy,and the relevant parameter indexes were calculated and the experimental results were analyzed.The results showed that the testing system meet the application requirements.
