With data quantity increasing dramatically and signal transmission period becoming more and more fast the media access control delay has proved to be one of the main influence factors of CAN network real-time. Firstly an equivalent numerical simulation model of CAN bus network is built to derivate the mathematical expression of media access control delay. Secondly optimization measures are further proposed to improve the data communication real-time. At last the optimization measures tested by experiments are proved to be correct and effective.

In order to realize the real-time state data monitor of the electromechanical actuator(EMA) the EMA and other subsystem establish a ground half physical experiment simulation platform based on the CAN bus. The CANoe software decodes the received EMA CAN data and showes the result in the image window. The decoding data contains the EMA current motor operation state EMA angle and etc. Through these real-time display data the EMA operation state could be monitored and the EMA failure could be located fastly. 2011 IEEE.

Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device it can be used for small aircraft flying field experiment. 2010 IEEE. as the main chip with DSP2812 SJA1000 as CAN controller CTM1050 as the CAN transceiver CF card as storage media. Gives the diagram of its hardware and software design process. Combined with the background of a small aircraft testing the instrument for data acquisition when the ground experiments and flight progress. Experimental data show that the design of high reliability and CAN signals can effectively complete the record

In order to increase the transmission distance and reduce noise effectively a communication system with the optical fiber interface is developed in this paper. In the system the PCI bus is adopted as the connection bus between the underlying optical fiber transceiver module circuitry and host computer using the WDM driver. The FPGA is the core logic of the whole system responsible for data transmission and timing logic control. The module structure and the design method of the PCI bus the principle and the design of optical interface module and the bottom-driven development are described in this paper. The experiment results show that the system has basically meet requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. With long transmission distance strong antiinterference and high scalability this system has stable and reliable performance. 2010 IEEE.

A new frequency characteristic test method is proposed based on the digitization characteristics of optoelectronic platform servo system. First a digital processing controller is used to automatically test the entire process and tested data are uploaded to a PC through CAN-bus and then the tested data are transferred into accurate transfer function with the Levy method. Here we discuss the testing steps the data processing the extraction the Bode diagram plotting and the model identification in detail. The corresponding experiments are carried out and the results show that the method is simple with the features of high efficiency high precision and engineering feasibility. 2010 IEEE.
