Abstract: Based on the remote monitoring and data processing technology, communication technology, control technology, designed a personal computer interface for the wave power generation remote monitoring and controlling system, through the GPRS and CDMA communication, designed the programmer under the Visual Basic 6.0 development environment. This communication interface can realize the communication and data processing, and achieved good effect, and save the investment.

Abstract: Sea or land rig requires a lot of roots in the drilling process. The catwalk-machine generally transports drill pipe to the second floor units. The rooted is established by dynamic rat holes, stored in boxes and taken from the rooted box during the drilling process. Automatic control systems for the rig on the stand of emissions complete automatic access of rooted. Previous control systems adopt the method of fixed access in order to complete the order for reducing control, although such control program is simple but the production efficiency is not high. In this paper, to access the walking path [1] in the process of the minimum as the optimization goal, not to block the internal root deposit box for qualification, designed a control algorithm to optimize the access path, which greatly improves access efficiency, reducing the distance of sports equipment, with high practical value.

Through the experiment, the system is stable and reliable, has the features of functional diversity, humanization design, can promote household CO₂ heat pump.

Abstract: The authors consider the problem of configuring regulators. This paper describes the selection of instrumental tools to create a mobile device, based on the real interpolation method, enabling to configure regulators without the use of mathematical software packages like Matlab or Mathcad. Also described are advantages and disadvantages of selecting hardware and software part for the mobile devise:

Abstract: We always regard aircraft power supply system as the "blood system" of aircraft. It plays a very important role in aircraft work. In view of its fault diagnosis present situation and in order to improve fault diagnosis efficiency, we put forward to use expert system development tool CLIPS to build up fault diagnosis expert system. In this paper, we choose the power-supply system of Cirrus SR20 as diagnosis object, and choose CLIPS as development tool to build up knowledge base and inference engine. By using Eclips development platform to write interface programs and using CLIPS JNI to call CLIPS programs we successfully complete the expert system total performance including knowledge base, inference engine and interface.

Abstract: The reliable hardware system is the guarantee of intelligent control to greenhouse environment. This paper made a simple description of greenhouse environment factors and their control equipments which directly affected system control, and summarized the hardware structure, characteristics, and application scope of some typical control systems in the greenhouse environment control. Prospect was also proposed for a further development of the hardware system according to the characteristics of the remote monitoring of greenhouse environment control system: it put forward a kind of system structure that achieved comprehensive remote monitoring of greenhouse environment using 3G network technology.

Abstract: This paper setup the hybrid automata control model of variable-frequency air conditioning by adopting Stateflow simulation toolbox of Matlab. The regulated quickness of the hybrid automata control model was simulated and validated by comparing PID control in Simulink. The hybrid automata control strategy was proposed in this paper for exploring hybrid features of the frequency conversion air conditioning control system. Comparing the traditional PID model, the result indicated the convergence speed of hybrid automata control strategy was faster to control the compressor operating frequency, better to simulate indoor energy balance, and to control the operation frequency state of the compressor. The paper showed the control strategy of hybrid automata control could achieve temperature control better, and the studied model has the better effects.

Abstract: This paper aims to design an intelligent street lighting controller based on solar energy and LED. The controller can work in daytime mode, dusk mode based on detection of light intensity and photovoltaic voltage, and head into night mode after a certain period of time when in dusk mode. While in night mode, a dimming scheme is applied by introducing motion detection with passive infrared (PIR) sensors. The controller also integrates a ZigBee based WSN to report street lights status periodically and get instructions from the remote control center. Moreover, it can enable more efficient management and lower maintenance costs.

Abstract: The production of facilities vegetable affected significantly by environmental factors, therefore it require real-time monitoring information of light, air temperature and humidity, soil temperature and humidity, and timely early warning and controlling, to prevent irreparable damage. This study achieved real-time monitoring and timely warning of environmental factors, and optimal control of pumps and roller blinds in the Facility vegetable. We have adopted Internet of Things technology and WCF communication interface, the system through C # language and the SQL Server database to prepare. The application in Jilin Province Jinta Industrial (Group) Co.Ltd. has showed that the system is better, achieved the purpose of high yield income.

Abstract: It has great significance for the capacitor reactive power compensation device to improve the quality of the power system voltage and reduce the line loss. This paper proposes a reactive power compensation measurement and control device scheme that integrates reactive power compensation with microcomputer protection function, it also can cover the shortage of the microcomputer relay protection of parallel capacitor reactive power compensation system, the whole system is linked by the RS485 bus. The paper mainly introduces the hardware design around the STM32 series micro controller. And then introduce the design of the software on main programming algorithm of parameter measurement, communication protocol and capacitor protection configuration and the criterion of the major programming algorithm.
