In industrial control fields, surveying and control systems compose huge numbers of sensors and data transmission systems, which have a great applications in marine and land seismic exploration. The system has characteristics of large coverage area, multi-channels device and remote data transmission, which bring problems in system synchronization, data transmission and storage, system management. To solve these problems, we design and realize a remote data acquisition and transmission system based on distributed architecture of serial concurrent bus. In this architecture, the system synchronous management of multi-channel devices, remote synchronous data transmission and a great number of real-time data processing are realized. The system with this architecture has the abilities such as simplicity to implement and upgrading, extensive application on distributed remote synchronous data transmission fields.

Aiming at the difficult problem of on-site real-time vibration responses monitoring and remote data transmission of the civil engineering structures, based on LabVIEW a remote data acquisition and transmission system is designed. In the system NI data acquisition card and DataSocket protocol of the LabVIEW software platform are used to realize data collection, remote transmission and control. That is, the civil engineering structural vibration responses can be monitored through internet at anytime and anywhere. The vibration parameters of a cantilever beam is detected and transmitted in real-time by using this system. The test parameter values are compared with the theoretical calculating value. The results show that relative to the traditional cable measurement and wireless short-range measurement, this system can effectively realize the remote real-time data acquisition, transmission, display, storage and control. Furthermore, the accuracy of data transmission is high. On the other hand, the system is easy to be built and maintained.

To shorten the time consumed for design computations in many engineering branches, the authors intend to use a new type computer system called array computer, which has hundreds of arithmetic units (AUs) connected in a multi-dimensional network. The most important, but difficult problem in design of this array computer is the development of an effective system of parallel data transmission between AUs. Hence this report deals with the development of this system, comparing the data transmission efficiencies of many conceivable systems. The results show that the effective arrangement of AUs is, (1) four- or five-dimensional array in the case of 1024 AUs, and (2) four- or six-dimensional array in the case of 4096 AUs. In both cases each AU is connected directly via data transmission lines with all AUs which lie on all coordinate axes passing through itself.

Seafloor observatories can provide long-term, real-time submarine monitoring data, which has great significance for the study of major scientific technology in marine science, especially in the seafloor earthquake observation. The chained submarine data sampling and transmission system is the prototype and foundation of cabled seafloor earthquake observatories. This paper designs and builds a chained data sampling and transmission system (SQSTS) based on Zynq-7000 Soc (System on chip) and clock synchronization. At the beginning, we realized high-precision submarine data (24 bit) sampling based on Zynq-7000 Soc and ADS 1256. Using the PPS (Pulse per second) signal provided by the P88 1588 PTP (Precise time protocol) clock synchronization board and the inner crystal oscillator of the Zynq-7000 Soc, the time stamp up to the microsecond level, for the seismic data sampled in each seismometer node can support subsequent inversion of seismic data. In addition, a high-speed data transmission link connecting nodes in SQSTS, which is based on the Gigabit transceiver and optical cable, has been investigated. The transmission link has been realized by using the Aurora IP core. The theoretical calculations indicate that the data transmission bus bandwidth can reach 4 Gbps, while in the meantime its reliability has been proved by experiments. The experimental results show that the system owns the characteristics of high data sampling accuracy, stable and reliable high-speed transmission, and has promising application prospects.

The construction of integrated data center provides data support services for energy smart city, which is inseparable from the aggregation of various data, such as electricity consumption information and power related data all over the city. Therefore, a stable and efficient data transmission system is needed to complete the data transmission work. But in reality, there are some problems such as the complexity of the public network environment, the diversity of data sources, and the security of source data. In order to solve the above problems, the data transmission system needs to have the following core functions: message forwarding, routing exploration, concurrent transmission, encrypted transmission, breakpoint continuation, error retransmission, etc. Based on socket communication, the system constructs a routing path from the source to the data center by exploring the routing nodes. By encapsulating the messages, the messages exchange and forward the information between the paths. For the source data with high security requirements, it encrypts the transmission. At the same time, it designs the transmission failure protection mechanism, which leads to connection problems in the transmission process, Connection recovery can continue transmission; at the same time, it can continue transmission for some unfinished tasks; it can automatically resend the failed data.
