The data extracted by piezoelectric acceleration sensor is more intuitive, more convenient.
But this method can not realize long distance real time monitoring, there are some shortcomings such as the piezoelectric sensor is still the traditional connection mode, when the number of measuring point is more, the test operation time will be in short [10]; and like that only one sensor can be arranged in a cross section, which can only measure the parameters of a specific section of real-time monitoring, but the long distance real-time changes of the parameters along the line is in need; moreover the data processing must be carried on after the end of the test, which can not monitor in real time.
The development of science and technology provides the possibility for solving the above defects, the distributed optical fiber sensing technology with its unique advantage is particularly worthy of esteem[11]: it can realize remote measurement and monitoring; it can carry on the long distance test, it has high performance ratio; the optical fiber can all become sensitive element, which can acquire the distribution information of measured the sensing area in real time; it can process data in real time, and it can achieve truly real-time monitoring, timely finding and solving the potential problems and harm.
The experimental method obtains data through tests, analyzes vibration propagation and environmental impact through the data.
During the choice of building materials, it is necessary to choose some greater rigidity material, such as while selecting the materials of the ground, the hard materials can be chosen, such as cement floor and terrazzo floor, which have good vibration reduction effect.

In this system,the literacy controller of SD card by SPI interface is designed based on FPGA.The overall design is realized in Nios II soft processor with C/C++ language,and the technology of First In First Out is used to solve timing problems,and then ultimately the overall design features are realized.This design takes advantages of the features of FPGA,which has reduction in development time,an efficient data processing,and other characteristics.The successful application in data storage collected by the audio chips shows that the design is feasible and valid.
In this system the SPI bus interface is used for data communication and FIFO technology is used to realize data clock synchronization, finally the SD card initialization and functions such as reading and writing operations are completed .
SPI interface controller Four lines is used by SPI interface:the serial clock line(SCK),the host input/slave output line(MISO),the host output/slave input line(MOSI) and the enable signal line(CS).FPGA is the host of the system.When the enable signal (CS) is low,data is sended in falling edge of the serial clock signal (SCK) and is read in rising edge.SPI is a ring bus structure as shown in Fig.2.When the CS signal is valid,the parallel data from the host is stored in the shift register and is converted into the serial data.Then the serial data is stored in SD card.At the same time the serial data in SD card is read and is converted into parallel data by the shift register when the CS signal is valid，then the parallel data is returned to the host.
Literacy controller The literacy controller has two components,the command controller and the data controller.Fig.3 is the block diagram of literacy controller.After the initialization,a written instruction or a read instruction is sended from the command controller to the SD card in the CS effective signal ( low level ) and waiting for the SD command response.When the SD command response is 0x00h,the status skips to the data controller.A data starting token (0xFE) was sended by the writing data controller after received the right writing command from the SD card and SD card is written into the corresponding data.Here the default data length is 512 byte,at the same time there are two bytes of CRC check bit.After finished these 512 bytes data,SD card come into the busy status and data write operation is completed.Read-write operation are inverse process, here no longer give necessary details.
The difference between the gathering rate of data and the reading and writing rate of SD card data maybe lead to discontinuous data or missing data.Increasing the reading and writing data cache can effectively solve this problem.When data is written or read,in order to avoid overflow or read in the empty state,it must be ensure that the FIFO can not be written in full state and can not be read in the empty state.The capacity of the buffer can be selected according to the rate of the data collected.The 16-bit width FIFO is used in this design.

Data available on the mechanical properties of maraging steel at elevated temperature are very scarce.
Specialized applications of the steel, such as the motor case of a solid propellant rocket, occasionally demand short-time exposures at high temperatures and it is desirable to have data on the hot tensile behavior of the material during such service conditions [5-8].
Software Blue Hill 2.6 was used for data acquisition.
This reduction in ductility can be also shown by fractography analysis.
However, the plasma nitriding treatment decreased the ductility (reduction in area) by 36% as a result of premature cracking of the compound layer.

For identification purposes of crystalline phase composition, diffraction pattern obtained were matched with standard diffraction data (JCPDS) files.
