Analysed the advantages of 3D configuration software and the issues which need to be resolved. Proposed the design method of semantic-based intelligent component library. Using ontology to describe the graphics components of the 3D configuration software. Analysed the feasibility of using Ontology in the 3D configuration software. Proposed the architecture of the 3D intelligent components. And described the method of describing the 3D components using ontology. Depending on the support of the ontology library, it can reduce the complexity and difficulty to create the 3D monitor scene by the 3D configuration software using the intelligent components. This makes the automation engineers create 3D monitoring scene so easily who has no 3D experience in the 3D development.

Most existing methods of Web data extraction realize goals based on DOM tree analysis or wrapper building. However,applicability and efficiency of these methods need to be further improved. According to the amount of information,Web pages will be divided into two structure types which are 1:1 and 1:N type respectively. As same type of Web pages has similar structure features,the paper proposes an approach of two-phase Web data extraction base on structure feature. In the phase of samples learning,structure feature and depository rules of Web pages are obtained according to the text feature of sample pages. In the phase of information extraction,Web data extraction is implemented by matching the page to be extracted with depository rules in knowledge base. Experimental results show that the approach proposed in the paper has well applicability and high efficiency.

An engine condition monitoring system was established with the Freescale MC9S12DG128 chip which self-equipped with the CAN bus controller. This system collects such key parameters as oil pressure and rotation speed,as well as trouble code information and so on through designed CAN nodes,and transmits these parameters to the remote monitoring center through GPRS modules. It is proven by tests that this system is able to well accomplish each function.
