Chapter 3 gives two examples of measurement and control system : testing platform of pc - based electric - bicycle and measurement system of high - pressure cleaner used for cars . it shows how they work . + also it includes the arichitecture of software and hardware . two important techniques : stucturued analysis and design technique ( sdat ) and prototyping requirements techniques are introduced in the two above systems 第三章从整体上介绍了电动自行车整车性能计算机检测系统的硬件构成和软件构成，同时也介绍了车用清洗机检测系统的原理与构成，研究了结构化的分析方法和快速原型开发方法在上述两个检测系统开发中的应用，并且讨论了数据库技术在检测系统中的应用。
( 3 ) by research the conformation and design rule of principle scheme design catalogues , clamp function design catalogue is researched by designing the clamp device of the electric bicycle automatic testing system . the design process of clamp function design catalogue is introduced from collectivity programming to each composed catalogue ( 4 )通过对原理方案设计目录构造和开发规律的研究，结合电动自行车自动检测系统夹紧机构的方案设计，对夹紧功能设计目录进行了研究，阐述了从目录总体规划到各个组成目录的详细构造的过程。
Finally , it is proved feasible to simulate the road - driving condition of electric bicycle on the testing platform . the collectivity programming of electric bicycle automatic testing system is maken out , including the simulated application strategy and method of road - resistance and wheeling inertia , design principle and evaluation system ( 2 )对电动自行车自动检测系统设计做出了总体规划，确定了行驶阻力与转动惯量的模拟策略和方法，明确了系统设计原则，建立了系统评价体系，运用多级模糊综合评价模型对各设计方案进行了评价选优。
