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. (2013) Trans Tech Publications

When CCD camera photographs massive images in the air
it is very important to compress and save CCD image timely and validly. This paper designs the CCD image compression and mass storage system. The one part is image compression: this paper introduces a reduced memory still image compression algorithm based on Listless Zerotree Coding (LZC). Compared with SPIHT
the approach significantly reduced memory requirement and no reducing the quality of the reconstructed image. The other part is image mass storage: this system uses a kind of special hard disk storage devices that can realize faster data transmission to SCSI (Small Computer System Interface) devices even if it separates oneself from PCs. In the faster data acquisition and storage system
data storage is a key technology. Normal approach is saving the data to mass memories
and then processing and saving the data after complete acquisition. The continuous acquisition time is restricted with the storage capacity in the normal method so that it can't receive the requirement of CCD image storage on many occasions. While its price will be geminate increasing
when we increase the storage capacity. So the approach in this paper is better one to use fast disks on data direct mass storage considering the storage capacity
read/write speed and unit cost. The result of the experiment shows that the system has compressed and saved CCD image validly
so it reached the anticipative purpose.
