Abstract: The field of glass deep processing has good prospect. However, the key technology of numerical-controlled glass cutter is primarily commanded by overseas large-scale companies. To meet the needs of the users and to develop the international competitiveness of the company, this paper makes the optimization design for numerical-controlled glass cutter. On the basis of analyzing the effects and the structures of main parts of the glass-cutter, the cutter machine is optimized in three aspects. The torsional vibration of transmission system is optimized by establishing the lumped mass-elasticity-damp discrete torsional vibration dynamic model with the multi-DOF. Applying the genetic algorithm and the finite element analysis software, this paper optimizes the beam weight under the condition of the approving rigidity of static and dynamic state. Finally design the basic structure of CNC glass cutter’s control system. This paper prefers the method of CNC glass cutter’s optimization and proves that the optimization suggestions are feasible and effective through tests.

Abstract: In this paper, a control system based on the prediction of processing flow in Abrasive flow machining is designed. In this system,flow is predicted by an improved GM(1,1) model in conformation of background value. Combined with fuzzy control system, it can adapt the pressure to meet the processing requirement automatically. Experiments proved that the improved GM(1,1) model can predict the processing flow accuratly, and the fuzzy control system based on grey prediction can improve the machining accuracy of micro-hole AFM effectively.

Abstract: This paper introduces the components of central air-conditioning system and compares the advantages and disadvantages of the PID control and fuzzy control.Fuzzy control theory and inverter technology are combined to design the Energy-Saving Monitoring System based on the fuzzy control box of STM32F103C8T6,Siemens S7-200 PLC, ABB inverter as the hardware system and interfaces configuration of KingView as the software. Experimental results show that the water system can be variable flow controlled based on the dynamic load, central air-conditioning energy efficiency the COP has greatly improved under the premise of ensuring the comfort of central air-conditioning.

Abstract: Wind power is emerging as a particularly attractive form of renewable energy. The predomination of Dielectric Electric Active Polymer (DEAP) has been shown to operate in transforming mechanical strain energy to electrical energy as generator mode. Their characteristics make them potentially well suited for wind power takeoff systems. In this article, a novel DEAP micro generator is successfully developed about mechanical-electro energy conversion model. The proposed energy harvesting is based on capacity change induced by the mechanical strain. With the Mooney-Rivlin model, the theoretical modeling of energy harvesting cycle are analyzed. To verify the theoretical analysis, the prototype has been set up on the DEAP wind power micro-generator in this work. Many experiments were performed to verify the usability of the proposed DEAP generator method. These experimental investigations coincide with the energy conversion theory analytical model. The DEAPs have been proved to provide electrical energy with density as high as 1.5J.g-1.This value is much higher compared with the density of piezoelectric polymer (0.3J.g-1). The work will push forward the practical use of wave power for supplying general electrical needs, and supply theoretical foundation for potential applications such as ocean wave power.

Abstract: With the progress of science and technology, the application of industrial Control System (ICS) is becoming more and more widely, meanwhile various security problems can not be ignored. This article introduces the security risks of ICS in the level of system design, safety management, natural disaster and personnel malicious attacks. It also gives some coping strategies to solve these given problems based on the security requirements stipulated in the related standards.

Abstract: Nowadays, with the in-depth development of networking, informatization and integration the access control system has become more and more popular and important in campus. Most access control systems were developed based on MCU with the characteristics of fixed functions and hardly to extend. A kind of campus intelligent access control system based on ARM is introduced in this paper. The overall structure of the system is as follow: the communication way between host computer and the access controller is TCP/IP protocol; using CAN-BUS for communication between access controller and RFID reader. In the design process, top-down design ideas has been adopted. From the overall structure to the local design, from the host computer to access controller and RFID reader, by means of functional analysis, process planning, hardware design and software programming, finally developed a campus intelligent access control system with excellent exhibitions on powerful, stability and scalability.

Abstract: In aviation industry, it’s urgent to build a scientific and effective knowledge system with high scalability to change the fact that the data is rich while the knowledge is deficient. We constructed the knowledge ontology of aircraft assembly with cyclic acquisition and seven step methods based on ontology thought. Then, we obtained the potential relationship related to process and abstract process ontology through logic reasoning. Finally, OWL is applied for ontology formal description to realize knowledge standardization and normalization. It’s meaningful to reuse, share the assembly process knowledge and further reasoning in the aviation field.

Abstract: This thesis introduces integrated house assembly simulation platform technology. It is divided into three categories: assembly simulation for the center with product design, assembly simulation for the center with assembly planning and assembly simulation for the center with virtual prototype. According to the characteristics of the integrated house assembly and modeling, it puts forward level assembly analysis method and studies the assembly system planning, assembly sequence planning and assembly path planning simulation technology. The results show that through the production system and assembly operation simulation technology research, it improves the rationality of the integrated house assembly process planning.
