汽车行业汽车制动试验台数据采 集处理系统研制 摘 要 本文主要研究内容是汽车检测线制动工位测控系统的研制。GB7258—2007 《机动车运行安全技术条件》中对汽车制动系统提出了主要技术条件,规定了台 式检验制动性能的检测项目及相关标准。根据要求设计了总体方案，根据检测实 际环境和技术要求具体设计了系统硬件和软件。 首先，在确立了对汽车制动性能参量检测及控制的总体方案后，根据各个参 量的特点设计了硬件检测电路。第二部分对软、硬件的可靠性设计、抗干扰措施 等方面进行了研究。第三部分研究了本系统所采用的数据处理方法。包括 FIR 数 字滤波算法。最后一部分对制动力测控系统进行了系统调试和性能试验，用前面 提到的数据处理方法处理实验数据结果达到预期要求。 关键词： 汽车制动性 测控检测系统抗干扰 数字滤波 FIR ABSTRACT This thesis designs automobile braking performance inspecting and control system. Some primary technical qualification of automobile braking has been brought forward in automobile safety technical condition.inspecting item and correlate criterion of table inspection braking performance has been prescripted in it. The hardware and software are designed according to practical need. In order to restrain the noise, the design of hardware anti-interference and digital filter is necessary. Firstly, establishing the blue print of auto braking performance inspecting and control system the hardware has been designed according to the characteristic of the parameter. The second part is the software and hardware reliability and anti-jamming has been researched. The third part is about data processing method including digital filtering arithmetic and data synthesizing technical, such as FIR digital filtering. In the last part, we did some system debug and performance test to braking inspecting system. According to the data gained by using the technical we said just now .
