4. Based on the analysis of the principle and structure of the intelligent roadway control system, the control of corresponding hardware device is implemented by the use of RS-485 interface and serial commutation technology.
The main contributions of this research include:(1) On the basis of studying the kernel principle and structure ofμC/OS-II, the shortcoming of the kernel’s interrupt has been pointed out. The idiographic improving methods from interrupt process and clock interrupt, have been put forward.
he concept,principle and structure of Computer Integrated Manuhcturing System(CIMS)and CIMS orien ted network are discussed in this paper. Some key problems are analysed. Some viewpoints are presented for the readers to have a thorough understanding and discussion.
A theoretical model of CAD expert systems is advanced by sum-marisation of the design ways that experts carried on and by analysis of AI method to solveproblems,with which two expert systems──the designs of simple and compound blank diesare constructed,the function,principle and structure of which are briefly introduced.
According to t he characteristic of DK-1 locomotive brake's principle and structure, this paper introduces the overall design of hardware-in-the-loop simulation for SS4G loc omotive brake system. Several showing methods of its work principle are compared and one method is selected.
