dacs data acquisition and control system
Examples
- The second part is a detector which is used to detect the distribution of voltage on the patient ' s brain surface from all different directions . the third is a mixed signal processor ( c8051f020 ) which is used to control the other parts of the system and display some necessary information and convert the voltage signals into digital signals , as well as transmit the acquired data to the computer . the fourth is computer with eit software which is used to analyze and process the received data and construct a picture for the brain edema and haematoma on screen
32通道电阻抗断层成像系统由4个部分组成：第一部分是正弦波恒流源，用来产生注入大脑的激励电流；第二部分是电位信号的提取与转换，用来提取当激励电流注入时，在大脑表面形成的电位分布信号；第三部分是数据采集与控制系统，用来控制激励电流的频率，注入方向，注入强度，控制采集大脑表面的电位分布信号，并且将这些采集的电位分布数据传到pc机；第四部分是计算机eit成像软件，用来接收下位机的电位分布数据，并且对这些数据进行分析计算，重建电阻抗图像。 - In this thesis , can bus is used as the system bus , concentrating the research on the feasibility of using redundancy can bus technology in large - scale motor vehicle safety performance detecting & control system . this thesis first gives an overall design of the data collection and control system applied to the front end of a large - scale motor vehicle safety performance detecting & control system . regarding that the bus controller , bus driver and bus transfer medium would fail to function easily , the dual mode cold - redundancy structure is adopted in system to ensure the reliability
本文采用can总线作为系统总线,重点研究冗余can总线技术应用于大型机动车安全性能测控系统的可行性并进行验证:首先对基于冗余can总线的机动车安全性能测控系统的前端数据采集与控制系统进行了总体设计,考虑到总线控制器、总线驱动器和总线介质都是容易出故障的部件,系统采用了二模冷冗余结构来保障can总线通讯的可靠进行;其次,根据系统需要,设计了基于c8051f021的带冗余can总线通道的数据采集与控制模块,用于采集与处理检测现场的模拟信号和数字信号,并自行开发了can总线应用层协议以及应用软件,通过冗余can总线实现与上位机的可靠通讯;然后,为了验证冗余can总线设计方案的可行性,搭建试验平台并进行can总线故障切换的试验;最后对课题的研究工作进行了总结与展望。 - In recent years , the embedded web has s served as one of most important approaches in measurement and control system . the paper has given an application framework of remote data acquisition and control system based on embedded web , utilizing mc9s12ne64 mcu integrated ethernet module brought out by freescale semiconductor
