Abstract: In the wind turbine gear fault detection, using conventional vibration monitoring exists installation and maintenance inconvenience and numerous other shortcomings, this often leads to the wind turbine vibration detection techniques are not widely promoted. Based on sensorless wind turbine gear fault diagnosis experiment research in this paper, the use of general-purpose inverter and induction motor, built a double-fed asynchronous induction generator simulation test bed, and had a broken tooth gear fault simulation experiments. Through the generator stator current signal and the gear vibration signal contrast and analysis, preliminary validation of the proposed method is effective and feasible.

Abstract: Organic light-emitting diode (OLED) has many advantages such as ultra light, ultra thin, high brightness, high definition, self-luminous, wide angle, quick response.It quickly attracts peoples attention to make one of today's hottest panel display subject. Based on the characteristics and working principle of OLED, the OLED display controlling circuit using the decoding module of DSP and controlling module of FPGA is designed.According to it,the use of each module in the circuit and the working process of the whole circuit are analysed.The simulations and tests are done.Verilog HDL is used to design the controlling circuit in the whole system and a top-down design method is used which is penetrated into each layer from top to bottom and devided carefully.The simulation results show that the gray scale display of OLED can be achieved and better display performance is obtained.

Abstract: There exists some problems of flux ripple and the switching frequency uncertainty in the traditional Direct Torque Control (DTC) .In order to improve the low-speed performance of the Machine direct torque control system, fuzzy direct torque control system is set up through fuzzy controller to replace Smith flip-flop ,we use fuzzy PI controller take place of traditional PI controller, also we establish the simulation model in the Matlab/Simulink environment, simulation results show that torque ripple and current distortion is decreased by use improved programs, can prove the effectiveness of this strategy.

Abstract: The management of saving energy is a weak link of Chinese industrial energy conservation at present. Modern industrial enterprise energy system shows characteristics as followed: the multielement of energy mediathe complication of Energy equipmentEnergy demand more targetingthe networking of Energy supply. The new change of system put forward the new requirements to the energy management. Due to early of energy management system (EMS) is focus on energy data acquisition and centralized monitoring, and the deep analysis of the energy system is not enough, so it can't use the useful information from energy data mining effectively, especially the optimization of energy use, and can not meet the requirements of it. The paper create the architecture energy conservation of Industry entirety, based on the pan under the environment of network, under the background of informationization and industrialization depth fusion iron and steel enterprises , Promoting the change of energy production and utilization means, making progress in comprehensive utilization of resources Energy conservation and emissions reduction, etc..

Abstract: The setup structure for the power grid faults diagnose system is analysed, the Multi-Agent System technique is used to the system. The functional modular of the system is transformed into Multi-Agent System, which has the same function as the entity system. The modular of the system can be in reconfiguration state when trouble appears by using Agent technique. The system running mechanism is also given.

Abstract: Agile manufacture execution system is the centre of whole system. The structure and function of the execution system are analyzed, the characteristics of Agent is also given. The Agent modeling method is used in the system, the function or unit can be transformed into Agent, so the setup structure for execution system of the agile manufacture system is build, and the resources, requirements are all brought into the networks. The systems operation relies on the interaction among the functional Agents.

Abstract: The six-component force measurement and real-time force feedback is not only the basis of multi-equipment coordination of operational control and the force comply with the control, but also to develop the technical basis of the overloaded operators, equipment and other heavy equipment. This article designed a fastening device based on the swelling principle of surface friction, for the six-component force sensor with parallel axis rigid connection. Analysis the six-component force sensor measurement principle, study the blessing device dynamometer performance of six-component force sensor. Use the finite element software for modeling and simulation analysis of the structure. Design of the loading experiments, the experiments show that the fastening technology based on the principle of swelling of the surface friction, to solve the six-component force sensor axis fixed and force transmission, interference of swelling structure to the sensor calibration is relatively small, both achieve effective clamping, but also improves the transfer efficiency of the power flow. With good positioning, highly repetitive assembly and disassembly, convenient adjusting device, etc.

Abstract: The detonating control method of Void-identify is one of the main methods in penetration ammunition detonating control. But during the process of penetration, the accelerometer in penetration ammunition will receives many interference signal so that affects the accurate burst control. Aiming to the problems of void-identify and anti-jamming in penetration process, the paper proposes a method to identify void and eliminates double-void interference by using the high-g accelerometer and Timer, and through comparing the range and duration of G. The system can controls the burst point accurately by Matlab simulating.

Abstract: Control the penetration ammunition burst point through layer-identify, As the target bunkers layer texture is complex ,it may leds to the burst point of ammunition can not in the expected. Such as a soft layer may be ignored by system , or a disturb layer by may be error identificated by system, etc. For those problems, the comparator and the timer is proposed with the combination of hardware system, this system can effectively prevents the layer-identify error, thus burst point can be precise controled. Through the simulation, the system can accurately apply.

Abstract: Based on the relation between the wavelength shift of sensing FBG and the strain, a flow measuring device of the circular target binding Fiber Bragg Grating with the cantilever is designed and the mathematical model based on a circular target flow measurement system is established. Through the flow experiment, we can get the flow test result. The experimental data error analysis can be concluded to verify the feasibility and precision of the design.
