Abstract: The design of software system for unmanned surface vehicle using PCI8602 is introduced. The software system includes the drive program of PCI8602, wireless transmission program and master controller program. Visual Basic is used to write programs, which doesn’t write complicated communication protocols between each layers and integrating subsystem is easy. At last, the experiment results demonstrate that the control system for USV has a way to real-time acquisition data, sending data and accomplishing remote control.

Abstract: Nowadays, the mobile display devices have become the most significant section of the mobile terminal. During nearly a decade development, lots of display technologies have been maturely applied in the mobile terminal instrument. This paper analysis the integrated application of several display technology utilized in mobile devices according to their characteristics, and predict the tendency of their development in the rapidly development stage of 3D display. Mobile terminal has become the mainstream of IT equipment, including intelligent mobile phone, pad computer and so on which is at a rapidly developing stage. On the other hand, currently technology on human machine interaction is concentrated in display devices, touch screen for instance.

Abstract: Design a things related technology based on remote monitoring system of temperature and humidity, sampling using SHT10 digital temperature and humidity sensors, temperature and humidity variables, and data transmission through the RS485 serial bus interface, using AVR kernel 8 bit chip for processing, resulting in a host computer display temperature and humidity changes, the indoor multi node the environment through the test, system has stable function, good display data change, relatively low cost advantages.

Abstract: Through the market investigation was designed based on the environmental monitoring system, intelligent control system and simulation system of security system, intelligent Home Furnishing system, this system uses CC2530 and sensors to build a ZigBee network, and realizes the remote monitoring through GPRS module, configuration of the PC software for the system, realized the function of intelligent furniture system through the actual test, that, the system is stable and reliable, practical.

Abstract: In view of the current situation of the development of smart substation, this paper analyses the standing domain information sharing, information network transmission delay effects on substation protection system. Based on above, advances the information transmission time delay of the solution. This paper uses the accurate computing information packet switches reside within the delay ΔT and into the sampling value (SV) message, giving to protection device. Protection device dependent on local time benchmark, the use of MU inherent latency and link to reside the total delay ΔT reduction received multiple interval sampling data of the moment, on the basis of implementing protection control function.

Abstract: detailed analysis of mathematical model, expounded maximum power point tracking (MPPT) control principle, then a improved constant voltage tracking of maximum power point tracking control based on GRNN neural network is proposed, this control strategy uses predicted voltage of GRNN neural network to instead of constant voltage, has be simulated in Matlab /Simulink, and result is this MPPT method can be more accurate compared to traditional control strategy.

Abstract: In order to overcome the disadvantages of ccomplexity of monitoring systems, inconvenience of installation for equipment and wiring, high error rate of data transmission, the technology of wireless sensor network is adopted. Through analysis of pond water testing results on the space distribution of water environmental factors, and the number and location of the sensor nodes is determined based on the distribution law of key factors. Experiments show that the system has higher accuracy and stability.

Abstract: As a most grievous meteorological disaster in the world, lighting calamity is destructive and could be inducement of fire explosion accidents. Lightning protection business mainly consists of lightning protection devices (LPD) inspection, lightning disasters authentication and lightning risk evaluation, for which on-site data gathering is indispensible, and the status in quo has common defects. Based on tablet-PC and mobile information technology, we developed a platform including such seven modules as system configuration, LPD inspection of existing buildings, LPD inspection of under-construction buildings, identification of lightning disasters, lightning risk assessment, location of inspected clients and location of inspectors. Mobil GIS technology and fast-developing method of forms were taken into use as key technologies. With its help, an promotion of facilitation, standardization and intellectualization of lightning protection business is achieved.

Abstract: According to the grey theory, in order to predict and prevent accident effectively, the paper built a grey model and forecast the mine accidents in china in 2013 based on the statistics of mine accidents happened in China during period from 2007 to 2012. MATLAB was used to write procedure code of GM (1, 1) and empirical verification follows. The prediction results show that if high accuracy goes with the precision of the calculable model, which could be used to provide the basis for decision making to the safety production management practices in China. This case study indicates that GM (1, 1) plays an important role in mine safety management.

Abstract: Many factories usually can’t use the production scheduling plan generated by some software directly, such as ERP and MES. Two main reasons are founded, one is the fixed parameter and data used in the planning and scheduling process; the other one is lack of Ability to respond to the dynamic production environment. This paper tries to improve the plan by using the dynamic information feedback and experience from workers, and a test states it is helpful in the daily work.
