- Firstly , the current testing localization in the detection of electric bow is analyzed and the new system ' s whole construction developed in this thesis is introduced ; in the 2rd chapter , the embedded 110v dc power supply is analyzed and constructed , and with experiments , some dissonant results such as the fluctuation of output pwm ( pulse width modulation ) pulses , the power noise added to output voltage , and the drop of output voltage have been analyzed and the problems have been broken down one by one ; in chapter 3 , stepping motor ' s drive has been systematically dissertated , and combing stepping motor ' s subdivided drive technology , the author develops an intelligent mini - step driving circuit using a main - sub microprocessor structure , which is validated in the hybrid stepper based system ; in the 4th chapter , liquid crystal driving and displaying technology is specified in detail , with one sort of lcd modules ( tlm12864h ) , the author develops an feasible circuit for the new testing system , designs a menu mode based program struc ture and brings here some programming codes using franklin c51 programming language ; in chapter 5 , the above built system is used in the electric bow ' s practical detection , and the differentiating rate of this system is analyzed
论文首先分析了目前机车受电弓检修方式存在的局限并概述了本论文研制的受电弓测试系统的体系架构；第二章对系统内置110v直流控制电源进行了分析和设计，结合试验对输出pwm振荡、输出电源噪声大、输出电压下跌等现象进行了分析并提出解决措施；第三章论述了步进电机的驱动，结合步进电机微步驱动技术研制了基于上下位单片机组的混合式步进电机智能驱动电路，并在试验中得以验证；第四章详述了液晶驱动及显示技术，利用一款液晶显示模块tlm12864h研制出本系统用液晶显示电路，设计了菜单式的程序结构并以franklinc51编程方式给出部分子程序代码；第五章则将以上构建的整个系统应用在机车受电弓的实测中，并对测试分辨率进行了分析。
