With RFID, ZigBee technology and NFC near field communication technology, as a representative of the content networking applications, are among the many enterprises, universities and the direction of research and development innovation. This paper ZigBee location technology application in coal mine, this paper introduces the principle and method of ZigBee positioning.

Abstract: With the continuous development of control technology, various areas of human activity, such as aviation, aerospace, exploration, production and other control techniques are demanding for increasingly higher requirements, one of which is on the remote control technology needs, especially remote control robot or facilities produced in accordance with the requirements to make certain human activities, productions and make them ordered to complete various tasks. We believe that with further improvement of automation technology and the advancement of human exploration, there will be more and more areas introduced to the remote control, and there will be new requirements for quality and performance of remote monitoring.

Abstract: In the previous studies of heart sounds, the calculation model of small waveform is often used, and new waveform graph is formed through the decomposition and restructuring of small waveform so as to remove the noise from the new waveform. There are a lot of shortcomings in the use of such a method. The features of new waveform are difficult to be controlled, and thus the noise generated by the wave and the interference of wave will be disturbed by the filter to certain degree. In this paper, the integrated filtering algorithm is introduced, and a wave can be used in the studied use of small waveform, and also the high-order algorithm in mathematics is used, so that the frequency is controlled in a certain range, the frequency of heart sounds to be interfered is effectively reduced, and also the harmonic harm generated by the waveform is considered. After the signal sources are protected with some technologies, the effect of filtering and denoising is eventually achieved.

Abstract: Aiming to meet the demand for real-time monitoring and adjustment in modern tailings management process, and solving the problems the development of technological innovations bring about ,this paper comes up with the establishment of this system for tailings based on LabVIEW. Utilizing the LabVIEW software platform, the ACCESS database and SQL language development technology, the paper is able to design various functional modules to optimize monitoring accuracy, data processing efficiency, and costs. The system can play a pivotal role in acquiring real-time change of the indicators, updating and sharing of the relevant data, which can finally assure the operation of tailings.

Abstract: Deep soil horizontal displacement monitoring can measure the retaining wall board, row piles deformed shape, reflect the foundation on the vertical profile of horizontal displacement with depth changes in the law, predict foundation stability and security risks. Combined with Wuhan WANGJiaDun Pit Engineering, this article introduce CX-3C inclinometer work principle, put forward the calculated optimization measures of inclinometer, and analysis the main factors which should be considered to arrange the measuring points.

Abstract: Competitive Aerobics in jumping ability is a special jumping ability, it not only requires jumping height, also called take-off speed and air attitude. Article put 28 students divided into experimental and control groups for a period of eight weeks of Spring Training. The experimental group used mainly jump and practice, the control group mainly continuous Straddle jump exercises. Before and after the experiment in the experimental group and the control group Calisthenics Bounce indicators and biomechanical testing, in order to reflect the effect of two kinds of training methods. Through experiments show that the use of single-chip technology, using jump and exercise, can improve the level of sports aerobics.

Abstract: with the development of science and technology, smart home systems require better, faster to meet the needs of human. In order to achieve this goal, the human-machine-items all need to interact each other with understand,efficient and speedy. Cps could unify combination with the human-machine-items; realize the interaction between the physical information and the cyber world. However,information interaction and the control task needs to be completed in a valid time. Therefore, the transform delay control strategy becomes more and more important. This paper analysis Markov delay control strategy for smart home systems, which might help the system decrease the transmission delay.

Abstract: In recent years, the digital watermarking technology has been widely used for the copyright protection of the digital images, and a lot of the digital watermarking schemes are proposed. This paper studies the application of shuffling techniques in the digital watermarking and proposes a standard measure of the scrambling degree. The criterion measure can help us judge to what extent an image should be scrambled in order to obtain the best robustness. Finally, this paper puts forward two kinds of scrambling technologies applied in the watermarking system, and the experimental results show that the scrambling technology is very effective in keeping resilience to cropping attack.
