Abstract: Dynamic vulcanized thermoplastic olefin/ organoclay composites were prepared in this paper. The morphology of the composites is studied with WAXD, which suggest organoclay shows good dispersion in TPV. The prepared TPV/organoclay composites improved mechanical properties significantly, the thermal property were also changed when organoclay is added. Besides, the content of curing agent and the addition of oil on the influence of properties were discussed.

Abstract: This paper has briefly introduced the construction situation of centralized control station (CCS) of Xuchang Power Supply Company, the modes and components status of Information Centralized Control System (ICCS), and analyzed the its existing problems and shortage. This paper has mainly stated the equipment features and function properties of RC3000, and described construction components and superiorities of ICCS in detail. It is meaningful for the construction of power system fibre-optical communication engineering and CCS in reference.

Abstract: According to the application of intelligent system for police GIS ,it needs to query and locateassist police,command and dispatch,patrol management and so on, According to the characteristics of police spatial information, All the spatial data needs to be unified storage. This paper designs the spatial database based on Geodatabase, then the database management for police is constructed and to achieve a unified and efficient management, so it provide an effective solution for the spatial data organization and management.

Abstract: A remote AMR system based on a STC90C52AD microcontroller and wireless network technology is presented in this paper to solve the problems in existing AMR system. Based on Smart Home system with grid demand side energy management, the automatic meter reading system centralizes electric power, water, gas meters, provides remote real-time automatic meter reading services and give instruction suggestions which contribute to energy management. Through the Web application platform, the users can use the Internet, mobile phones and other means to achieve the remote monitoring of the household appliances, energy-saving and saving house electricity costs. This AMR system has been implemented successfully by the State Grid Corporation Shandong Electric Power Group Corporation and the department of Automation of Wuhan University in collaboration.

Abstract: A remote indoor environment monitoring system based on a STC90C52AD microcontroller and wireless network technology is presented in this paper to solve the problems in existing environment monitoring system. With a Web control platform, the environmental monitoring systems can remotely monitor the indoor environment, and scientifically guide users to improve the indoor environment. The environmental monitoring module is communicated with display terminal, so that users can use PC, mobile phone or Pad to achieve the remote monitoring for indoor environmental via the Internet, GPRS, 3G and other networks. To improve the quality of life while achieve intelligent management. This system has been implemented successfully by the State Grid Corporation Shandong Electric Power Group Corporation and the department of Automation of Wuhan University in collaboration.

Abstract: A new steering control strategy for active four-steering vehicle is studied based on the steering-by-wire and intelligent information technology in this paper. An ideal model-tracked of vehicle steering is established and an optimal active steering controller is designed on the basis of the 2 degree-of-freedom vehicle dynamic model. The simulation result shows that this optimal controller on front-rear wheel steering angle not only improve the transient and steady-state response characteristics of vehicle, but also follow the ideal steering model accurately. Therefore, the maneuverability and stability of vehicle are enhanced consequently.

Abstract: Truck scale can be on-line monitor cargo weight, so it is widely used in weighing. The requirements and the basic composition of the truck scale weighing monitoring system is introduced. The requirement analysis of the truck scale weighing monitoring system is carried through and the functions of the weighing monitoring system are detailed analyzed. The network monitoring system architecture and software architecture is designed. Truck scale weighing monitoring system is analyzed using UML and the Use Case diagram is given. The truck scale weighing monitoring system is designed. The experimental results show that truck scale weighing monitoring system has good openness and security and can improve the enterprise efficiency.

Abstract: Truck scale is one of the important weighing equipment. To on-line remote monitoring truck scale cheating devices, new truck scale on-line remote anti-cheating system is brought out and truck scale on-line remote anti-cheating system is designed. The remote anti-cheating system includes the anti-cheating monitoring terminal, CAN and GPRS transmission module and remote weighing anti-cheating system. Truck scale anti-cheating monitoring terminal collects the anti-cheating data and sent to the remote anti-cheating system through CAN and GPRS transmission module. The experimental system is built and the experiment is carried out. The experimental results show that the on-line remote anti-cheating system of the truck scale can on-line monitor truck scale cheating devices and improves the system security.

Abstract: Truck scale is widely used in weighing cargo weight. To monitoring truck scale, truck scale remote weighing method based on the GPRS and CAN bus is brought out and the on-line weighing monitoring system is designed. The weighing monitoring system includes truck scale weighing system, the control center monitoring system and the remote weighing monitoring system. The cargo weight is collected by the weighing system and sent to the control center monitoring system through CAN. The remote weighing monitoring system receives the cargo weight through GPRS. The experiment system is built. The experiment result indicates that truck scale remote weighing system can monitoring the cargo weight and improves the system security and accuracy and the communication efficiency.

Abstract: Worm infection is a critical problem for network application technology and security. In order to decrease the destruction of worm to network application technology, a worm containment method using benign worms was proposed, and an approach of high-fidelity modeling on packet-level of worm propagation and containment with benign worms was designed. The experiment results show that benign worms can contain the infection of malicious worms effectively, and the initial locality of worm, the delay time between the start time of benign worm and malicious worm, background traffic of the network will affect the propagation and containment of worms.
