摘　　要：嵌入式技术ETC系统开发在社会智能化的发展中起着重要作用。ETC系统分别由传感器系统、投影数据采集系统和图像重建单元系统组成,3个系统相互关联,可以进行系统内的数据传输和指令控制。根据ETC的工作原理进行影像构建算法,计算结果表明,电容板内侧结构图像误差分析可以判断影像构建的清晰度,结构两端极板的电容值和管道结构的介电常数为线性关系,管道内侧电容值的增加量由分布在管道壁的介电常数决定。研究结果对嵌入式ETC系统开发提供了技术支撑。Embedded technology ETC system development plays an important role in the development of social intelligence.The ETC system consists of a sensor system,a projection data acquisition system,and an image reconstruction unit system.The three systems are related to each other and can perform data transmission and command control within the system.According to the working principle of ETC,the image construction algorithm is carried out.The calculation results show that the image error analysis of the inner structure of the capacitor plate can judge the sharpness of image construction.The capacitance value of the plate at both ends of the structure is linear with the dielectric constant of the pipe structure.The amount of increase in capacitance is determined by the dielectric constant distributed across the wall of the pipe.The research results provide technical support for the development of embedded ETC systems.
