The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC  which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1  and is used as the core part of the system. As a new try  the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.   Miniature field bus data recorder (EI CONFERENCE) 会议论文 2010 WASE International Conference on Information Engineering, ICIE 2010, August 14, 2010 - August 15, 2010, Beidaihe, Hebei, China Chen C.-Q.; Ji Y. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 The common bus on bus control is RS232. With the development of field bus technology  field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000  a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage  which should have abroad application prospect for data record experiment. 2010 IEEE.   Implementation and stability analysis of the fuzzy controller based on electric-driven simulation turntable (EI CONFERENCE) 会议论文 ISECS International Colloquium on Computing, Communication, Control, and Management, CCCM 2008, August 3, 2008 - August 4, 2008, Guangzhou, China Xie M.-J.; Wang L.-M.; Wang Z.-Q. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 Fuzzy controller was used to resolve the problem of fast tracking and overshoot in electric-driven simulation turntable  for its essence belongs to PD control In this system  the control rules of fuzzy controller were established according to the step dynamic response process  for the speed loop of this system was predigested to be second-orders system. The describing function method was adopted to analyze the stability of the fuzzy control system. It gave the information of stability of system intuitively. The fuzzy controller had been applied in this system successfully. The simulation turntable had no overshooting nearly when its step input signal was close to 90. Experimental results show the implementation method of fuzzy controller is not only simple but also effectual in engineering practice. It also provides an approach of design of fuzzy controller for motion control system. 2008 IEEE.
