AbstractThe dissertation discusses the principle of automatic instrument for measuring standing long jump, and its development and realization in detail. Having four schemes in the beginning, comparing and analyzing their feasibility and economy, at last we have chosen the scheme based on the single-chip microprocessor. The dissertation mainly includes: the discussion of the principle based on single-chip microprocessor, the extension of ROM, RAM and input/output interface, designing the circuit diagram with the help of software Protel99; Based on the hardware circuit diagram, we have edited the assemble language program , and have debugged and simulated it by the use of software Proview32.We have optimized the structure of the program. The dissertation curtly describes optimized the design of the instrument structure and considers the effects of the interference.
