The graphical interface is one of the basic components of the monitoring configuration software, which has a great impact on the software. However, a variety of configuration software currently used different graphic styles to form the monitor screen, so that different systems interact difficultly. To overcome this shortcoming and improve the reusing rate of code writing monitor screen and enhance applications efficiency of dealing with a lot of graphics information, this paper sets up a monitoring graphics elements library of configuration software, which uses SVG recommended by the international image formats of monitoring interface, and elaborates the way to define equipment element property. Integrating Batik project of ASF (Apache software foundation) and adopting Object Orient Design Thought, the paper analyses and designs the monitoring graphics elements library module of configuration software. Configuring graph's properties as the corresponding with relational SQL datebase which facilitate the programmer inputs data, can improve the total level of the configuration software.

Multidimension 01 knapsack problem is a typical NonDeterministic Polynomial problem. In view that ant colony algorithm solving often have local optimum and slow convergence speed problems, this article propose an improved ant colony algorithm. Based on the introduction of leap frog algorithm clustering thought, the ants have been developed into two groups with different culture, which improves the global search ability. The greedy strategy modified formula is applied in order to improve the accuracy of calculation. The formula is further simplified by roulette algorithm. Simulation results indicated that the modified algorithm improves the accuracy and global search ability.

The traditional envelope spectrum method does not accurately extracting characteristic problems in rolling bearing fault diagnosis, so a new energy and envelope spectrum based on a combination of timewavelet energy envelope spectrum analysis was developed. The various parts of rolling collected data the two methods were analyzed and compared, and show that the proposed method was better than the traditional envelope spectrum and could accurately extract the rolling bearing fault characteristic frequency.
